Description
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a service transmission method and device.
Background
Internet television (IPTV) is a typical Internet Protocol (IP) multicast service, and a terminal device (e.g., a set top box (set top box) or a Customer Premise Equipment (CPE)) may request to join/leave a multicast group through an Internet Group Management Protocol (IGMP) or a multicast listener discovery protocol (MLD) to receive/terminate an IP multicast service provided by a corresponding multicast group. For IPTV service, the delay experience when a user changes channels is very important, generally, the acceptable channel switching delay of people should be within 1 second, and if the channel switching delay exceeds 2 seconds, there will be obvious delay and pause, and the user is easy to feel bored.
In order to reduce the time delay of channel switching, a fast channel switching (FCC) mechanism is introduced in the existing optimization design for IPTV experience, and the principle of the mechanism is shown in fig. 1, and includes: 1) the FCC server caches the video information of certain channels of the terminal equipment; 2) when a user sends a channel switching instruction through a remote controller, terminal equipment requests a target channel program stream from an FCC server; 3) the FCC server updates the multicast data in a manner higher than the multicast rate (e.g.: 1, N times multicast rate) unicast pushing a target channel program stream starting with a key information frame (i.e., I frame) to a terminal device, and sending a multicast unicast synchronous notification message to the terminal device; 4) in the process of executing 3), the terminal device sends an IGMP/MLD message to the network side device to exit the multicast group where the current channel is located, and sends an IGMP/MLD message to apply for joining the multicast group corresponding to the target channel after receiving a multicast and unicast synchronization notification message sent by the FCC server; 5) after the FCC server sends out the multicast unicast synchronous notification message, the unicast push rate can be properly reduced, and the target channel program stream is sent; 6) the terminal equipment joins the multicast group corresponding to the target channel, receives the multicast packet of the program stream of the target channel, and informs the FCC server of the sequence number of the received first multicast data packet. 7) When the data packet sequence number sent by the FCC server in a unicast mode is connected with the first multicast data packet sequence number, the FCC server stops the unicast sending, and the terminal equipment continues the normal multicast receiving service flow.
As shown in fig. 1, the existing FCC mechanism mainly reduces the channel switching delay through signaling interaction between the terminal device and the FCC server and unicast data push with a higher rate, so in order to better support IPTV services in a mobile network and improve user experience, signaling interaction between the terminal device and the FCC server and unicast push rate of the FCC server need to be guaranteed, and the problem of high channel switching delay caused by that signaling interaction between the terminal device and the FCC server and downlink unicast push rate are not satisfied is avoided.

Fig. 12 is a flowchart of a service transmission method provided in this embodiment, where the method may be applied to the 5G network shown in fig. 2a, and is used to implement differentiated air interface transmission guarantees for different types of services.
Step 1201: the first management device acquires the PCC rule, and determines the corresponding relation between the SDF and the QoS flow and the corresponding relation between the QoS flow and the QoS parameter according to the acquired PCC rule.
The corresponding relationship may be replaced by a mapping relationship, a corresponding relationship or an association relationship, without limitation.
The PCC rule may be obtained by the first management device interacting with the second management device, or may be preconfigured in the first management device. The first management device may be the SMF in fig. 2a, and the second management device may be the PCF in fig. 2 a.
Each set of QoS parameters includes a Guaranteed Flow Bit Rate (GFBR), and optionally, a Maximum Flow Bit Rate (MFBR), a session aggregation Maximum Bit Rate (session-AMBR), a UE aggregation Maximum Bit Rate (UE-AMBR), an Aggregation Guaranteed Flow Bit Rate (AGFBR), an Aggregation Maximum Flow Bit Rate (AMFBR), and the like. The GFBR is a bit rate provided for a Guaranteed Bit Rate (GBR) QoS flow guarantee, and the MFBR is a maximum bit rate that the GBR QoS flow can provide, which can be used to limit a data transmission rate of a service, and in general, a value of the MFBR is generally greater than or equal to a value of the GFBR. It should be noted that each set of QoS parameters includes, but is not limited to, the above, and may also include other parameters, such as a 5G QoS Identifier (5G QoS Identifier, 5QI) and corresponding 5G QoS characteristics (5G QoS characteristics, including, for example, resource type, delay budget, allowed error rate, scheduling Priority, etc.), Allocation and Retention Priority (ARP), etc., without limitation.
Optionally, in the correspondence between the QoS flow and the QoS parameter determined by the first management device, the first QoS flow corresponds to a set of QoS parameters, that is, a set of QoS parameters is set for one QoS flow. For example, as shown in fig. 12a, QoS flow1 corresponds to QoS parameter 1, QoS flow2 corresponds to QoS parameter 2, GFBR included in QoS parameter 1 is G1, GFBR included in QoS parameter 2 is G2, QoS flow2 is expected to be transmitted at a guaranteed transmission rate of G2 during time t1, and QoS flow1 is expected to be transmitted at a guaranteed transmission rate of G1 during time t 2. For ease of description, in the embodiments of the present application, the QoS flow is transmitted, meaning that packets mapped to QoS flow are transmitted, for example, the QoS flow1 is transmitted, meaning that packets mapped to QoS flow1 are transmitted, and so on.
The set of QoS parameters may correspond to at least two QoS flows, where the at least two QoS flows may include a first QoS flow, that is, a set of QoS parameters is set corresponding to the at least two QoS flows, and when the at least two QoS flows are transmitted, transmission needs to be performed according to the QoS parameter requirements, and the sum of the QoS requirements of the at least two QoS flows must not exceed the specified range of the QoS parameter. For example, as shown in fig. 12b, QoS flow1, QoS flow2 correspond to QoS parameter 1, GFBR included in QoS parameter 1 is G1, MFBR is M1, and transmission rate 1 when QoS flow1 is transmitted alone in time period t1 should satisfy: g1 ≦ Transmission Rate 1 ≦ M1, and Transmission Rate 2 when QoS flow2 alone was transmitted during t2 should satisfy: g1 is not less than 2 and not more than M1, and the transmission rate 3 when the QoSflow1 and the QoS flow2 are jointly transmitted in a t3 time period should satisfy the following conditions: g1 is less than or equal to transmission rate 3 is less than or equal to M1, namely the sum of the two transmission rates is not lower than G1 and not higher than M1.
The first QoS flow may correspond to at least two sets of QoS parameters, that is, one QoS flow is provided with at least two sets of QoS parameters, at least two sets of QoS parameters may correspond to time periods, and the QoS flow is transmitted according to different parameter requirements at different time periods. For example, as shown in fig. 12c, QoS flow1 corresponds to QoS parameter 1 and QoS parameter 2, the GFBR included in QoS parameter 1 is G1, the GFBR included in QoS parameter 2 is G2, QoS flow1 is expected to be transmitted at the guaranteed transmission rate of G1 during time t1, and QoS flow1 is expected to be transmitted at the guaranteed transmission rate of G2 during time t 2.
At least two QoS flows may correspond to at least two sets of QoS parameters, where the at least two QoS flows may include a first QoS flow, such as: in an alternative manner, at least two QoS flows correspond to GFBRs in at least two sets of QoS parameters one to one, and at least two QoS flows correspond to MFBRs in one set of QoS parameters, that is, at least two QoS flows correspond to aggregated MFBRs (aggregated MFBRs, AMFBRs). For example, the GFBR corresponding to QoS flow1 is G1, the GFBR corresponding to QoS flow2 is G2, and the AMFBR parameter corresponding to QoS flow1 and QoS flow2 is M3, which means that when QoS flow1 and QoS flow2 coexist in a certain period of time, the sum of the transmission rates provided by the network to the two flows does not exceed M3.
Or, in another optional manner, when at least two QoS flows are transmitted separately, the at least two QoS flows correspond to GFBRs in at least two sets of QoS parameters one to one, and when at least two QoS flows are transmitted together, the at least two QoS flows correspond to Aggregated GFBRs (AGFBRs) in one set of QoS parameters, that is, the at least two QoS flows correspond to AGFBRs. For example, as shown in fig. 12d, the GFBR corresponding to QoS flow1 is G1, the GFBR corresponding to QoS flow2 is G2, and the AGFBR parameter corresponding to QoS flow1 and QoS flow2 is G3, that is, when QoS flow1 and QoS flow2 coexist in a certain period of time (e.g., t3 in fig. 12 d), the sum of guaranteed transmission rates provided by the network to the two flows is G3.
It should be noted that, in each embodiment of the present application, for two different sets of QoS parameters, some or all of the parameters may be different, and at least one set of QoS parameters corresponding to the first QoS flow is a burst QoS parameter corresponding to a burst service flow.
In embodiments of the present application, the QoS flow may be uniquely characterized by a service identifier, which may be an identifier for identifying the QoS flow, such as: QFI, may also be an identification of QoS requirements for identifying this type of QoS flow, such as: 5QI, it should be noted that QoS is a specific embodiment of the requirement, and alternatively, the QoS requirement may be equal to QoS, that is, the QoS requirement may be replaced by QoS in the embodiment of the present application, which is not limited.
The QFI and 5QI may be numbers, letters, or other identifiers, which are not limited in this embodiment of the application. For example, QFI1 may be used to identify QoS flow1, and 5QI1 may be used to identify QoS requirements of QoS flow 1.
When the QoS flow is characterized by a service identifier, the correspondence between the at least one set of QoS parameters and the at least one QoS flow may be replaced by a correspondence between the at least one set of QoS parameters and the at least one service identifier (QFI or 5QI), such as: one service identifier corresponds to one set of QoS parameters, or one service identifier corresponds to at least two sets of QoS parameters, or at least two service identifiers correspond to one set of QoS parameters, or at least two service identifiers correspond to at least two sets of QoS parameters.
Optionally, before step 1201, the second management device (e.g., PCF) may interact with a network device, for example, a service server or a service platform, to negotiate a service requirement (e.g., a service rate guarantee requirement), and the second management device generates a PCC rule according to the negotiated service requirement, and provides the PCC rule to the first management device, so as to execute step 1201.
Optionally, in step 1201, the first management device determines, according to the obtained PCC rule, a corresponding relationship between the SDF and the QoS flow, and a corresponding relationship between the QoS flow and the QoS parameter, which may refer to a relevant description in the protocol (TS 23.501). For example, assuming that the first management device is an SMF, the second management device is a PCF, and the PCC rule negotiated and obtained by the SMF and the PCF includes an SDF template (template), where the SDF template includes a set of packet filtering rules for mapping a packet to the SDF, and the packet filtering rules may be set according to part or all of IP quintuple information (including source IP address/IPv 6 network prefix, destination IP address/IPv 6 network prefix, source port number, destination port number, and transport layer protocol type) of the packet, for example, that satisfies a preset condition (for example, the destination IP address is a specified address, the port number is within a specified range, the protocol type is Transmission Control Protocol (TCP), and after mapping the packet onto the SDF according to the packet filtering rules, the SMF may further bind the SDF to a QoS flow that can satisfy the QoS requirement of the SDF (for example, 5 flow and priority reservation (priority and priority) in a set of QoS parameters of the QoS parameters, ARP), the QoS flow is bound with the SDF as the 5QI and ARP for SDFQoS requirements). Alternatively, multiple SDFs may be bound to the same QoS flow.
Step 1202: the first management device sends the QoS configuration information to the access network device.
The first management device may send QoS configuration information to the access network device through a third management device (e.g., AMF), where the QoS configuration information includes: the first management device (SMF) may send a message including QoS configuration information to the third management device (AMF) through an N11 interface, where the QoS configuration information may include a correspondence between at least one service identifier and at least one set of QoS parameters, and the AMF sends the message including the QoS configuration information to the access network device through an N2 interface after receiving the message. Optionally, the SMF sends the message containing the QoS configuration information to the access network device through the AMF, and further includes an authorized QoS rule sent to the terminal device, where the authorized QoS rule may be used by the terminal device to map a data packet of the uplink service onto a QoS flow and send the data packet to the access network device.
The QoS configuration information may comprise a correspondence of at least one set of QoS parameters to at least one service identity (QFI or 5 QI). The correspondence between the at least one service identifier and the at least one set of QoS parameters may be described with reference to step 1201, and is not described herein again.
Or, the QoS configuration information may include a corresponding relationship between a service identifier and QoS parameters and first indication information, where the corresponding relationship between the service identifier and the QoS parameters is used to indicate a corresponding relationship between QoS flow and QoS parameters, one service identifier is used to represent one QoS flow, the corresponding relationship between the service identifier and the QoS parameters at least includes a corresponding relationship between a first service identifier and at least one set of QoS parameters, the first service identifier is used to represent the first QoS flow, and the first indication information is used to indicate a burst QoS parameter corresponding to a burst traffic flow in the QoS parameters corresponding to the first service identifier.
Step 1203: the access network device receives the QoS configuration information.
The access network device may receive QoS configuration information sent by the first management device through the third management device, where the QoS configuration information includes: the access network equipment receives the message containing the QoS configuration information sent by the third management equipment (AMF), and obtains the QoS configuration information from the message, wherein the QoS configuration information is received by the third management equipment (AMF) from the first management equipment (SMF).
Optionally, if the message received by the access network device from the AMF includes the authorized QoS rule sent to the terminal device, the access network device sends the message including the authorized QoS rule to the terminal device.
Step 1204: the first management device sends configuration information related to the service flow to the gateway device, and the gateway device receives the configuration information related to the service flow.
In a possible scenario, the gateway device may be a UPF shown in fig. 2a, and optionally, the gateway device and the terminal device establish a data transmission channel, such as: protocol data unit session (pdu).
The gateway device may receive a message containing traffic flow related configuration information via its interface with the first management device, e.g. the N4 interface, and obtain the traffic flow related configuration information from the message.
The configuration information related to the service flow includes, but is not limited to, one or more of the following information: SDF template (SDF template), SDF priority, identification information of QoS flow corresponding to SDF (such as QFI), QoS parameter information (e.g., including GBR, MBR, session-AMBR), etc., the SDF template may include: the packet filtering rule set may include at least one packet filtering rule, where the packet filtering rule is used by the gateway device to map the data packet to the SDF, and further to map the data packet to a QoS flow corresponding to the SDF, and the QoS parameter information is used by the gateway device for QoS control when the data packet is sent.
Step 1205: and the gateway equipment receives the data packet, maps the received data packet to the first QoS flow according to the configuration information related to the service flow, and sends the mapped data packet to the access network equipment.
In a possible example, the data packet received by the gateway device may be a data packet sent by a network device (e.g., an FCC server, a router, etc.) in a data network to a terminal device, such as: data packets of a certain IPTV live program 1. Optionally, the data packet includes IP quintuple information, such as: the protocol type, the source IP address, the destination IP address, the source port number, and the destination port number, where the source IP address may be a network address of the network device, the destination IP address may be a network address of the terminal device, the source port number may be any transport layer port number of the network device, and the destination port number may be any transport layer port number of the terminal device. Optionally, a gateway device, such as a UPF, receives data packets originating from network devices in the data network via the N6 interface.
The mapped data packet corresponds to a qos flow, and the mapped data packet may carry a service identifier (e.g., QFI or 5QI) that characterizes the qos flow.
Optionally, mapping, by the gateway device, the received data packet onto the first QoSflow according to the configuration information related to the service flow, where the mapping includes: the gateway device classifies the data packet into a data packet of a first SDF (service data flow) based on the SDF priority in the configuration information related to the service flow and a packet filtering rule contained in the SDF template if the data packet is matched with the first SDF filtering rule, for example, when all or part of IP quintuple information of the data packet meets preset conditions (such as a destination IP address is a designated address, a port number is in a designated range, and a protocol type is TCP), the data packet can be classified into the first SDF data packet; further, the gateway device remaps the received packet onto the first QoS flow according to the identification information (for example, QFI1) of the first QoS flow corresponding to the first SDF. It should be noted that, in the embodiment of the present application, the data packets that do not satisfy the packet filtering rule included in the SDF template may be mapped to a default QoS flow for sending, or discarded or cleared (clear).
For example, in the embodiment of the present application, a data packet corresponding to a certain IPTV live program 1 belongs to the SDF1, where at the UPF, the data packet of the program 1 is classified into a data packet of the SDF1 according to a packet filtering rule in the SDF template, and in configuration information related to a service flow received by the UPF, an identifier of the QoS flow1 corresponding to the SDF1 is QFI, so that the UPF maps the data packet of the program 1 to the QoS flow1 and sends the QoS flow to the access network device, and then the access network device sends the QoS flow to the terminal device, so that QoS requirements of the data packet of the program 1 in a transmission process are guaranteed.
The QoS parameter according to which the gateway device sends the data packet to the access network device may include: the GBR, optionally, further includes a Maximum Bit Rate (MBR), where the GBR indicates a bit rate that is expected to be provided for the QoS flow guarantee corresponding to the data packet, and the MBR indicates a maximum bit rate that can be provided for the QoS flow guarantee corresponding to the data packet, and may be used to limit the data transmission rate of the data packet, and in general, a value of the MBR is generally greater than or equal to a value of the GBR, and the QoS parameter may be obtained from the configuration information related to the traffic flow received by the gateway device in step 1204. Such as: the configuration information related to the service flow in step 1204 may further include a QoS parameter corresponding to the SDF or the QoS flow, and the gateway device sends a data packet to the terminal device according to the QoS parameter; the QoS parameter may be activated when some preset conditions are met, and deactivated when other preset conditions are met. Specifically, the process of activating or deactivating the QoS parameter by the gateway device under the preset condition may refer to the following related description, which is not described herein again.
It should be noted that, in the embodiments of the present application, activation may refer to: validating certain configurations (e.g. a certain bearer/QoSflow, or some or all of the QoS parameters corresponding to a certain bearer/QoS flow), such as: turning on/enabling/running certain configurations, deactivation may refer to: disabling certain configurations (e.g., a certain bearer/QoS flow, or some or all of the QoS parameters corresponding to a certain bearer/QoS flow), such as: certain configurations are turned off/disabled/deleted. Optionally, when some configurations are deactivated, context information related to those configurations may be retained.
Step 1206: and the access network equipment receives the data packet from the gateway equipment, and sends the data packet to the terminal equipment through the second bearer according to the QoS parameters required by the service corresponding to the data packet according to the corresponding relation between the QoS flow and the QoS parameters.
The service corresponding to the data packet is a burst service or a non-burst service, and the QoS parameter required by the service corresponding to the data packet is a set of QoS parameters in the QoS parameters corresponding to the first QoS flow.
The second bearer may be a Radio Bearer (RB), and the radio bearer may include time domain resources, frequency domain resources, space domain resources, code domain resources, and the like.
The data packet received by the access network device may include information indicating the first QoS flow, or the data packet received by the access network device includes information indicating the first QoS flow and information used for indicating a QoS parameter required by a service corresponding to the data packet; or the access network equipment also receives information indicating the first QoS flow and information used for indicating the QoS parameters required by the service corresponding to the data packet; the information indicating the first QoS flow may be a first service identifier, the first service identifier is used for characterizing the first QoS flow, and the information indicating the QoS parameters required by the service corresponding to the data packet may be: the QoS parameter may be a burst QoS parameter or a set of non-burst QoS parameters, or information indicating whether a service corresponding to the data packet is a burst service, or information indicating a certain set of parameters corresponding to the data packet, such as a QoS parameter identifier.
Optionally, the sending, by the access network device, the data packet to the terminal device through the second bearer according to the QoS parameter required by the service corresponding to the data packet according to the correspondence between the QoS flow and the QoS parameter includes: the access network equipment determines that the data packet corresponds to a first QoS flow according to information indicating the first QoS flow, such as QFI or 5QI, maps the data packet to an RB according to the mapping relation between the first QoS flow and the RB, provides an air interface bearer for the data packet, determines a QoS parameter required by a service corresponding to the data packet according to the information indicating the QoS parameter required by the service corresponding to the data packet, and transmits the QoS parameter to the terminal equipment through the RB according to the QoS parameter.
The mapping relationship between the first QoS flow and the RB may be determined by the access network device, for example, the access network device determines according to a QoS parameter corresponding to the QoS flow and a QoS parameter of the RB, such as: the access network device may determine, according to a corresponding relationship between the service identifier and the QoS parameter in the QoS configuration information or according to a corresponding relationship between the service identifier and the QoS parameter of a preset standard, a QoS parameter corresponding to the service identifier carried by the data packet, that is, a QoS parameter corresponding to the QoS flow represented by the service identifier, select or establish an RB that can meet the QoS parameter requirement of the QoS flow according to the QoS parameter corresponding to QFI/QoS flow and the QoS parameter of the RB, and form a mapping relationship between the selected or established RB and the QoS flow.
Illustratively, QoS flow1 and QoS flow2 map to RB1, QFI1 identifies QoS flow1, QFI2 identifies QoSflow 2; QoS flow3 is mapped to RB3, QFI3 identifies QoS flow3, when data packets received by the access network equipment contain QFI1, QoS flow1 is determined to be mapped to RB1 according to the mapping relation between QoS flow and RB, and the data packets are mapped to RB1 and sent to the terminal equipment.
It should be noted that, the above steps 1201-1204 may be executed before the gateway device receives the data packet as shown in fig. 12, or may be executed after the gateway device receives the data packet or the related service request information and the gateway device does not find a proper QFI or QoS parameter corresponding to the data packet, which is not limited herein. For example, after the gateway device receives a data packet from the network device, or after the gateway device receives a specific service (or service flow) request message from the terminal device, the QFI and/or QoS parameter corresponding to the data packet is not found, and a request message for requesting QoS configuration information, such as a PDU session modification request, or a QoS flow establishment or revision request, is sent to the first management device, so as to trigger the execution of step 1201 and 1204.
Optionally, in order to reduce signaling interaction between devices, in the scheme shown in fig. 12, a terminal device may further provide a QoS parameter requirement of a service, and an access network device temporarily adjusts an air interface bearer for a burst service according to the QoS parameter requirement of the terminal. For example, the terminal initiates a QoS parameter adjustment request to the access network device for a QoS flow corresponding to a certain burst service, where the QoS parameter adjustment request may include QFI and a QoS parameter suggested to be adjusted, and the access network device sends a data packet to the terminal device through a second bearer according to the QoS parameter required by the service corresponding to the data packet according to the QoS parameter adjustment request, so as to provide an air interface bearer for the corresponding QoS flow.
Optionally, in order to avoid that data packets with different QoS requirements are handled as packets with the same QoS requirements by the network, in step 1205 shown in fig. 12, the data packet received by the gateway device may include additional information, where the additional information is used to identify the QoS requirements corresponding to the data packet, so that the gateway device may parse the additional information, map the data packet to an appropriate QoS flow (e.g., a first QoS flow) with reference to a packet filtering rule configured by the first management device (e.g., an SMF), and select an appropriate QoS parameter (e.g., a QoS parameter that satisfies the QoS requirements of the data packet) for the data packet; or, the gateway device sends parameter indication information to the access network device according to the additional information, where the parameter indication information is used to indicate the access network device to select a QoS parameter that meets a QoS requirement corresponding to a data packet for sending a QoS flow (e.g., a first QoS flow) of the data packet.
In a possible implementation manner, the additional information is a tag, for example, a video quality tag, which is used to indicate requirements of definition, rate, and the like of a video stream corresponding to the data packet, where the video quality tag may be determined by the network device, or may be determined by negotiation between the network device and the first management device, or the second management device, or the gateway device, where the first management device may be, for example, SMF/AMF, etc., the second management device may be, for example, PCF/PCRF, etc., and the gateway device may be, for example, UPF, etc.
For example, in an IPTV service, the definitions (e.g., standard definition, high definition, 4K, etc.) of data packets corresponding to different target channels requested by a terminal device are different, and the rates of the data packets of different target channel programs may have a large difference in a channel change process of a user. In an optional manner, a packet filtering rule in the SDF template configured for the gateway device considers a video quality tag attached to the FCC server, and the gateway device may analyze the tag and map different data packets to different qos streams according to the packet filtering rule in combination with information carried by the tag, so as to realize that different definition programs select different qos streams for transmission, and avoid that different program streams are mapped to the same qos stream due to the consistency of IP quintuple information. In another optional manner, a packet filtering rule in the SDF template configured for the gateway device does not consider a video quality label attached to the FCC server, where data packets from different target channels of the FCC server are mapped by the gateway onto the same QoS flow and sent to the access network device, and then sent to the terminal device by the access network device, where the QoS flow may correspond to multiple sets of QoS parameters, and the gateway device may parse the video quality label carried in the data packet and carry parameter indication information (e.g., QoS parameter indication information or the video quality label) in the data packet sent to the access network device, so as to instruct the access network device to select a set of appropriate QoS parameters for the QoS flow.
Thus, in the scheme shown in fig. 12, when a data packet is sent, scheduling is performed according to the qos requirement of the data packet, an air interface bearer is allocated, and the data packet is sent to the terminal device through the air interface bearer, thereby ensuring transmission of the data packet.
As a reverse process of data packet transmission, another embodiment of the present application further provides a service transmission method, which is specifically shown in fig. 13.
Step 1301: the access network device stores the QoS configuration information.
The QoS configuration information may be obtained by the access network device from the management device, and the QoS configuration information may include a correspondence between the QoS flow and the QoS parameter. Specifically, the QoS configuration information may refer to the description in the scheme shown in fig. 12, and is not described herein again.
Step 1302: and the terminal equipment sends the data packet to the access network equipment.
Wherein, the data packet sent by the terminal device carries the identification (such as QFI) of QoS flow.
Step 1303: and the access network equipment receives the data packet and sends the data packet to the gateway equipment through the first QoS flow according to the QoS configuration information and the QoS parameters required by the service corresponding to the data packet.
The service corresponding to the data packet is a burst service or a non-burst service, and the QoS parameter required by the service corresponding to the data packet is one set of QoS parameter in the QoS parameters corresponding to the first QoS flow.
Optionally, the sending, by the access network device, the data packet to the gateway device through the first QoS flow according to the QoS parameter required by the service corresponding to the data packet according to the QoS configuration information includes: the access network equipment determines that the data packet received by the access network equipment corresponds to a first QoS flow according to the identifier carried by the data packet, determines a QoS parameter corresponding to the first QoS flow according to the corresponding relation between the QoS flow and the QoS parameter, and sends the QoS parameter to the gateway equipment through the first QoS flow.
Step 1304: and the gateway equipment receives the data packet sent by the access network equipment through the first QoS flow and sends the data packet to the network equipment.
The network device may be a server, a router, or the like.
Thus, in the scheme shown in fig. 13, when the terminal device sends a data packet to the network device, that is, when the data packet is sent uplink, the data packet is mapped onto the QoS flow according to the QoS requirement of the data packet, and the data packet is sent to the network device through the QoS flow, which ensures the transmission of the data packet.
Optionally, in order to reduce the delay impact on service transmission caused by temporarily establishing the QoS flow for the burst service flow and reduce the impact on the admission capacity of the mobile network caused by the burst service flow, at the access network device, all or part of the QoS parameters (such as the QoS parameters corresponding to the burst service flow) corresponding to the service identifier in the received QoS configuration description are in an inactive (inactive) state, and at this time, the QoS parameters corresponding to the burst service flow may be activated according to an actual requirement (such as that the burst service flow comes). For convenience of description, in the embodiments of the present application, some or all of the QoS parameters are referred to as burst QoS parameters. For example, the burst traffic flow may include a target channel program flow that is fast-pushed by the FCC server through unicast, and when the target channel program flow that is fast-pushed by the FCC server through unicast passes, the access network device activates a burst QoS parameter corresponding to fast channel switching.
Optionally, the correspondence between the service identifier and the QoS parameter in the QoS configuration description received by the access network device may further include: the first indication information is corresponding to a first service identifier and a burst QoS parameter corresponding to the first service identifier, and is used for indicating that a first QoS flow represented by the first service identifier can be used for carrying a certain type of burst service flow, and the burst QoS parameter configured for the first QoS flow is enabled only when corresponding burst service needs exist. For example, the service identifier 1 corresponds to QoS parameter 1 and QoS parameter 2, and the first indication information may indicate that the QoS parameter 1 is the burst QoS parameter corresponding to the service identifier 1.
Optionally, the access network device may activate the first QoS flow, or the burst QoS parameter corresponding to the first service identifier, or the burst QoS parameter corresponding to the first QoS flow and the first service identifier under a first preset condition, where the first preset condition is: a data packet received by the access network equipment carries a first service identifier; or, the data packet received by the access network device carries information for indicating the burst service flow corresponding to the data packet; or, the access network equipment receives information for indicating to activate the burst QoS parameter corresponding to the first QoS flow.
For example, the access network device activates the corresponding QoS flow and/or burst QoS parameter when at least one of the following conditions exists, the access network device determines the mapping relationship between the QoS flow and the RB according to the QoS parameter corresponding to the QoS flow and the QoS parameter of the RB, and maps the data packet to the RB according to the RB mapped by the QoS flow and transmits the data packet to the terminal device.
Case 1: the access network equipment receives a data packet of a certain burst service flow, and activates a burst QoS parameter corresponding to a first service identifier according to the first service identifier carried in the data packet.
In an optional manner, a first service identifier (e.g., QFI1) is used to characterize a first QoS flow, where the first QoS flow is only used to send a burst traffic flow, and if an access network device receives a data packet sent by a gateway device or a terminal device and carries the first service identifier, the access network device activates a burst QoS parameter corresponding to the first service identifier. For example, in the QoS configuration description received by the access network device, QFI1 corresponds to QoS parameter 1, and there is first indication information (such as burst indication) indicating that QoF flow1 identified by QFI1 corresponds to a certain burst traffic flow (e.g., FCC unicast traffic flow), and QoS parameter 1 is a burst QoS parameter, so for the access network device, QoS parameter 1 is generally in an inactive state, and when the access network device receives a data packet carrying QFI1, the QoS parameter corresponding to QFI1 is activated: QoS parameter 1.
Case 2: the access network equipment receives a data packet of a certain burst service flow, and activates a first burst QoS parameter corresponding to a first service identifier according to the first service identifier and second indication information carried in the data packet.
In an optional manner, the gateway device carries a first service identifier (e.g., QFI1) and second indication information in a data packet of a burst service flow sent to the access network device, where the second indication information is used to indicate that the data packet corresponds to the burst service flow and a burst QoS parameter corresponding to the first service identifier needs to be activated, and optionally, the second indication information may also be used to indicate that a specific set of burst QoS parameters needs to be activated, such as the first burst QoS parameter, and when the access network device receives the data packet carrying the first service identifier and the second indication information, the first burst QoS parameter corresponding to the first service identifier is activated.
Case 3: and the access network equipment receives a data packet of a certain burst service flow, and activates a second burst QoS parameter corresponding to the first service identifier according to the first service identifier and the third indication information carried in the data packet.
In an optional manner, the gateway device carries a first service identifier (e.g., QFI1) and third indication information in a data packet (e.g., a first data packet corresponding to a burst service flow) sent to the access network device, where the third indication information is used to indicate that a QoS flow corresponding to the first service identifier will carry a certain burst service flow within a preset time (e.g., within a future period of time), optionally, the third indication information may also be used to indicate that a certain set of burst QoS parameters, such as a second burst QoS parameter, is specifically activated, and after receiving the data packet carrying the first service identifier and the third indication information, the access network device activates the second burst QoS parameter corresponding to the first service identifier;
correspondingly, in another optional manner, the gateway device carries a first service identifier and an end instruction for instructing to end the transmission of the burst service flow in a data packet (for example, a last data packet corresponding to the burst service flow) sent to the access network device, and the access network device deactivates the burst QoS parameter corresponding to the first service identifier after receiving the data packet carrying the first service identifier and the end instruction information. For the specific description, reference may be made to the following description of the access network device deactivating the burst QoS parameter, which is not described herein again.
For example, in the QoS configuration description received by the access network device, the service identifier QFI1 corresponds to QoS parameter 1 and QoS parameter 2, the GFBR included in QoS parameter 1 is G1, the GFBR included in QoS parameter 2 is G2, and there is first indication information (such as burst indication) indicating that QoF flow1 identified by QFI1 corresponds to a certain burst traffic flow (e.g., FCC unicast traffic flow), and QoS parameter 1 is a burst QoS parameter corresponding to QFI 1; thus, at the access network device, QoS parameter 1 is typically in an inactive state, QFI1 and QoS parameter 2 correspond; after receiving a data packet carrying QFI1 and a burst start tag (burst start marker), the access network equipment activates and enables a burst QoS parameter-QoS parameter 1 corresponding to QFI1, wherein QFI1 corresponds to QoS parameter 1; when the access network equipment receives a data packet carrying QFI1 and a burst end tag (burst end marker), the QoS parameter 1, which is a burst QoS parameter corresponding to QFI1, is removed, so that QFI1 corresponds to QoS parameter 2.
Case 4: and the access network equipment receives the fourth indication information and activates the burst QoS parameter corresponding to the first QoS flow according to the fourth indication information.
Wherein, the first QoS flow may be used for carrying a burst traffic flow. The fourth indication information is used for indicating the access network equipment to determine that the burst QoS parameter corresponding to the first QoS flow needs to be activated. The fourth indication information is sent by the terminal device to the access network device, or sent by the management device to the access network device (e.g., the SMF is sent to the RAN device via the AMF).
In a possible manner, the access network device receives fourth indication information from the terminal device, where the fourth indication information includes a service identifier (such as QFI1) of the first QoS flow and/or a burst service request, where the burst service request is used to indicate that the terminal device has a burst service requirement, and the access network device activates a burst QoS parameter corresponding to the first QoS flow according to the fourth indication information. For example, QFI1 corresponds to QoS parameter 1 and QoS parameter 2, the GFBR included in QoS parameter 1 is G1, the GFBR included in QoS parameter 2 is G2, QoS parameter 1 is a burst QoS parameter and is in an inactive state, after the access network device receives fourth indication information (including QFI1 and a burst request, for example) sent by a Radio Resource Control (RRC) message by the terminal device, the access network device activates the burst QoS parameter corresponding to QFI1 according to the fourth indication information: QoS parameter 1.
In another possible mode, the access network device receives fourth indication information from the terminal device, where the fourth indication information includes a burst service request and/or QoS requirement information of the burst service, and the QoS requirement information of the burst service is a QoS parameter requirement corresponding to a burst service flow requested by the terminal device; and the access network equipment selects the QoS flow and the corresponding QoS parameter which can meet the burst service requirement of the terminal equipment according to the fourth indication information, and activates the QoS parameter if the QoS parameter is in an inactivated state.
In another possible manner, the access network device receives fourth indication information from the management device (e.g., from the SMF to the RAN device via the AMF), where the fourth indication information includes a service identifier (e.g., QFI1) of the first QoS flow, and optionally, a burst QoS parameter (e.g., QoS parameter 1) to be activated corresponding to the first QoS flow; and the access network equipment activates the burst QoS parameter of the first QoS flow according to the fourth indication information.
Correspondingly, the access network device deactivates the first QoS flow, or the burst QoS parameter corresponding to the first service identifier, or the first QoS flow and the burst QoS parameter corresponding to the first service identifier under a second preset condition, where the second preset condition is: the access network equipment receives an end instruction for indicating the end of the burst service flow; or, the access network device determines that a timer corresponding to the bursty service flow is overtime.
For example, the access network device may deactivate the first QoS flow and/or its corresponding bursty QoS parameters (e.g., some or all of the QoS parameters corresponding to the bursty traffic flows) in the presence of at least one of the following conditions to avoid degrading the overall admission capacity of the communication network.
Case 1: and the access network equipment receives an end instruction for indicating the end of the burst service flow, and deactivates the first QoSflow and/or the corresponding burst QoS parameter.
In a possible manner, a network device, such as an FCC server, carries an end indication in a data packet (e.g., the last data packet of a burst traffic flow) sent to a gateway device, so as to indicate that the burst traffic flow ends; the gateway device sends an end instruction to the access network device, where the end instruction is used to indicate that the burst service flow ends, optionally, the end instruction may also be used to indicate that a certain set of burst QoS parameters are specifically deactivated, and after receiving the end instruction, the access network device deactivates the burst QoS parameters corresponding to the burst service flow. Optionally, after receiving an end indication that indicates that the burst service flow ends, the gateway device deactivates the burst QoS parameter corresponding to the burst service flow.
The gateway device sends the end indication to the access network device, which has many possible implementation manners, for example, the gateway device (e.g. UPF) carries a service identifier and an end indication in a data packet (e.g. the last data packet of a burst service flow) sent to the access network device, and the access network device deactivates a burst QoS parameter of a corresponding QoS flow according to the service identifier and the end indication; or, the gateway device (e.g. UPF) sends information indicating the end of the burst traffic flow to the first management device (e.g. SMF), and then the first management device (e.g. SMF) sends a message including an end indication to the access network device via the third management device (e.g. AMF), optionally, the message including the end indication further includes a service identifier, and after receiving the message including the end indication, the access network device deactivates the burst QoS parameter of the corresponding QoS flow.
In another possible mode, a network device, such as an FCC server, sends a message (e.g., a unicast and multicast synchronization notification message sent by the FCC server to the terminal device) for indicating the end of a burst service stream to the terminal device, and then the terminal device sends an end indication to an access network device for indicating the end of the burst service, and after receiving the end indication, the access network device deactivates a burst QoS parameter corresponding to the burst service.
Case 2: and the access network equipment sets a timer corresponding to the burst service flow, and if the timer is overtime, the first QoS flow and/or the corresponding burst QoS parameter are/is deactivated.
In a possible manner, a timer is set in the access network device, and is used to limit an effective time of a burst service flow received by the access network device, and the time duration of the timer may be set according to needs.
Similarly, in order to reduce the delay impact on service transmission caused by temporarily establishing the QoS flow for the burst service flow and reduce the impact on the admission capacity of the mobile network caused by the burst service flow, for the gateway device, optionally, the QoS parameter configured for the burst service flow may also be enabled when needed, that is, generally in a deactivated state, and when there is a burst service demand, the QoS parameter corresponding to the burst service is selected to be activated.
In an optional manner, the receiving, by the gateway device, the configuration information related to the service flow further includes: the gateway device may activate, according to the indication information, after the gateway device receives the information indicating that the burst service flow is about to be performed, some or all QoS parameters corresponding to the SDF or the QoS flow, that is, select some QoS parameters corresponding to the burst service flow for activation, and for convenience of expression, the some or all QoS parameters may be referred to as burst QoS parameters.
For example, the gateway device may activate the first QoS flow, or the burst QoS parameter corresponding to the first QoS flow, or the first QoS flow and the burst QoS parameter corresponding to the first QoS flow under a third preset condition, where the third preset condition is: the gateway equipment receives information used for indicating the burst service flow to be sent; or, the gateway device receives information including a burst service requirement corresponding to the burst service stream.
For example, the gateway device activates the first QoS flow and/or its corresponding burst QoS parameter in case 1 or case 2 described below.
Case 1: the gateway device receives information indicating the burst traffic flow to be sent (e.g., sending the burst traffic flow to the terminal device) from the network device, and activates the first QoS flow and/or its corresponding burst QoS parameter.
The information indicating the upcoming bursty traffic flow includes, but is not limited to: burst traffic flow packets sent by the network device, such as unicast streams of user request target channels sent by the FCC server to the terminal device; or a notification message sent by the network device to the terminal device for confirming the burst traffic flow, for example, a zapping response message sent by the FCC server to the terminal device.
Case 2: and the gateway equipment receives the information which is from the terminal equipment and contains the burst service requirement corresponding to the burst service flow, and activates the first QoS flow and/or the corresponding burst QoS parameter.
In a possible manner, the information indicating the burst traffic demand includes but is not limited to: burst service request information sent by a terminal device to a network device, for example, a fast zapping request message sent by the terminal device to an FCC server, and/or a burst service resource request sent by the terminal device to a core network device, for example, a QoS flow resource request sent by the terminal device to a UPF/SMF, and/or QoS requirement information of a burst service, where the QoS requirement information of the burst service is a QoS parameter requirement corresponding to a burst service flow requested by the terminal device; the gateway equipment can select QoS flow adaptive to the burst service requirement of the terminal equipment and corresponding QoS parameters according to the information indicating the burst service requirement, and activate the QoS parameters if the QoS parameters are in an inactivated state.
Correspondingly, the gateway device deactivates the first QoS flow, or the burst QoS parameter corresponding to the first QoS flow, or the first QoS flow and the burst QoS parameter corresponding to the first QoS flow under a fourth preset condition, where the fourth preset condition is: the gateway equipment receives an end instruction for indicating the end of the burst service flow; or, the gateway device determines that a timer corresponding to the bursty traffic flow is overtime.
For example, the gateway device may deactivate the first QoS flow and/or its corresponding bursty QoS parameters (e.g., some or all of the QoS parameters corresponding to the bursty traffic flows) in the presence of at least one of the following conditions to avoid degrading the overall admission capacity of the communication network.
Case 1: and the gateway equipment receives an end indication for indicating the end of the burst service flow and deactivates the first QoS flow and/or the corresponding burst QoS parameter.
In a possible manner, a network device, such as an FCC server, carries an end indication in a data packet (e.g., the last data packet of a burst traffic flow) sent to a gateway device, so as to indicate that the burst traffic flow ends; the gateway device sends an end instruction to the access network device, where the end instruction is used to indicate that the burst service flow ends, optionally, the end instruction may also be used to indicate that a certain set of burst QoS parameters are specifically deactivated, and after receiving the end instruction, the access network device deactivates the burst QoS parameters corresponding to the burst service flow. Optionally, after receiving an end indication that indicates that the burst service flow ends, the gateway device deactivates the burst QoS parameter corresponding to the burst service flow.
The gateway device sends the end indication to the access network device, which has many possible implementation manners, for example, the gateway device (e.g. UPF) carries a service identifier and an end indication in a data packet (e.g. the last data packet of a burst service flow) sent to the access network device, and the access network device deactivates a burst QoS parameter of a corresponding QoS flow according to the service identifier and the end indication; or, the gateway device (e.g. UPF) sends information indicating the end of the burst traffic flow to the first management device (e.g. SMF), and then the first management device (e.g. SMF) sends a message including an end indication to the access network device via the third management device (e.g. AMF), optionally, the message including the end indication further includes a service identifier, and after receiving the message including the end indication, the access network device deactivates the burst QoS parameter of the corresponding QoS flow.
In another possible mode, a network device, such as an FCC server, sends a message (e.g., a unicast and multicast synchronization notification message sent by the FCC server to the terminal device) for indicating an end of a burst service stream to the terminal device, and then the terminal device sends an end indication to an access network device and/or a gateway device for indicating an end of the burst service, and after receiving the end indication, the access network device and/or the gateway device deactivates a burst QoS parameter corresponding to the burst service.
Case 2: and the gateway equipment sets a timer corresponding to the burst service flow, and if the timer is overtime, the first QoSflow and/or the corresponding burst QoS parameter are/is deactivated.
In yet another possible manner, a timer is provided in the gateway device, and the timer in the gateway device is used to limit the effective time for the gateway device to receive the burst traffic flow. After the timer in the gateway device is overtime, the gateway device deactivates the burst QoS parameter corresponding to the burst service flow, optionally, the gateway device sends an end indication to the access network device, where the end indication is used to indicate the access network device to deactivate the burst QoS parameter corresponding to the burst service flow. For the embodiment that the gateway device sends the end instruction to the access network device, reference may be made to the above description about sending the end instruction to the access network device by the gateway device, which is not described herein again.
Optionally, in order to reduce power consumption of the access network device, after the access network device receives a scheduling request message sent by the terminal device or after the access network device receives a scheduling instruction sent by the gateway device, the access network device starts an air interface scheduling function, so as to implement a process of sending a data packet through an air interface resource and activating/deactivating a corresponding burst QoS parameter when sending the data packet.
The scheduling request message is used for requesting the access network device to provide scheduling guarantee for a data packet of the burst service flow, and the scheduling request message is a message sent by the terminal device after the terminal device receives a fast channel switching instruction, or the terminal device receives a response message from the network device, or the terminal device receives the burst service flow from the network device.
The scheduling indication is used for indicating the access network device to provide scheduling guarantee for the received data packet of the burst service flow, and the scheduling indication is an indication sent after the gateway device receives a response message from the network device or receives the burst service flow from the network device for the first time.
The first management device is an SMF, the second management device is a PCF, the gateway device is a UPF, the network device is an FCC server, the terminal device includes a set-top box and a premise equipment CPE, and there are two IPTV live channels watched by the user: the schemes shown in fig. 12 and 13 are described by taking as an example that the rate and definition of the program stream for each channel are different for channel 1 and channel 2.
The SMF interacts with the PCF to obtain PCC rules (rules), determines the corresponding relation between the SDF and the QoS flow according to the PCC rules, allocates QFI for the QoS flow and determines the corresponding QoS parameter, wherein the QoS parameter comprises GFBR, the SMF sends a message containing QoS configuration information to the access network equipment through AMF, and the QoS configuration information comprises QFI and the corresponding QoS parameter: for example, QFI1 corresponds to QoS parameter 1, QFI2 corresponds to QoS parameter 2, QFI3 corresponds to QoS parameter 3, QFI1 identifies QoSflow1, QFI2 identifies QoS flow2, and QFI3 identifies QoS flow3, where QoS flow1 and QoS flow2 serve a burst traffic flow, and QoS parameter 1 and QoS parameter 2 corresponding to both are in an inactive state.
At a certain moment, a user sends a channel change command to the set top box through the remote controller to request to switch to the channel 1. After receiving the channel switching command, if the requested channel 1 supports fast channel switching, the set top box sends a message requesting for a target channel program stream to the CPE, the CPE sends a data packet containing the message requesting for the target channel program stream to the access network equipment through an air interface bearer, after receiving the data packet, the access network equipment determines that the data packet corresponds to QoS flow1 according to the corresponding relationship between the air interface bearer and the QoS flow, the corresponding QoS parameter 1 is in an inactivated state, then the access network equipment activates the QoS parameter 1, maps the data packet carrying the QFI1 tag to QoS flow1 according to the activated QoS parameter 1, sends the data packet to the gateway equipment, and then the gateway equipment sends the data packet to the FCC server.
After receiving the message requesting the program stream of the target channel, the FCC server sends the program stream corresponding to channel 1 to the UPF in a unicast manner, optionally, a data packet corresponding to the program stream carries a quality label (for example, a label indicating video quality, channels 1 to 3 are respectively corresponding to 720P, 1080P, and 4K), and the UPF analyzes the quality label, and maps the program stream to the QoS flow1 to send to the access network device in combination with a packet filtering rule in the sdfsemplate sent to the UPF by the SMF. After receiving the data packet, the access network equipment determines that QoS flow1 corresponding to the data packet serves as burst service flow according to QFI1 carried in the data packet, wherein corresponding QoS parameter 1 is in an inactivated state, then the access network equipment activates QoS parameter 1, maps the data packet carrying the QFI1 label to an air interface bearing RB1 according to the activated QoS parameter 1, and sends the data packet to the CPE, and then the CPE sends the data packet to the set-top box. When the FCC server finishes sending the program stream of the channel 1, the FCC server sends an end instruction for instructing to end unicast sending of the channel 1 to the access network device, and the access network device deactivates the QoS parameter 1 according to the end instruction.

The service transmission method will be described in detail below with reference to the service transmission apparatus.
Fig. 20 is a flowchart of another service transmission method according to another embodiment of the present application, where the method may be applied to the 4G network shown in fig. 2b, and is used to implement differentiated air interface transmission guarantees for different types of services.
Step 2001: the gateway device stores configuration information related to the traffic flow.
Wherein the gateway device may be a PGW.
The configuration information related to the service flow may be obtained according to a PCC rule, where the PCC rule is obtained by a gateway device from a management device (e.g., PCRF), or statically configured in the gateway device.
The configuration information related to the service flow may include a service flow template (TFT), a correspondence between bearers and QoS parameters, and indication information, where the TFT includes at least one packet filtering rule, the packet filtering rule is used to map a data packet onto a bearer, the correspondence between the bearers and QoS parameters includes a correspondence between a first bearer and burst QoS parameters, the indication information includes information used to indicate the first bearer and information used to indicate the burst QoS parameters corresponding to the first bearer, the first bearer corresponds to a burst service flow, and the burst QoS parameters correspond to a burst service flow.
Step 2002: and the gateway equipment establishes a bearer with the terminal equipment according to the configuration information related to the service flow.
The bearer in the embodiment of the present application may be an Evolved Packet System (EPS) bearer, where the bearer includes a first bearer, and the QoS parameter may correspond to the EPS bearer and be used to indicate a QoS requirement of a service mapped to the bearer, and therefore, the QoS parameter may be referred to as a service-related QoS parameter.
Optionally, each set of QoS parameters includes a bearer rate parameter, and the bearer rate parameter may include: GBR, optionally, also contains MBR. The GBR is a bit rate guaranteed and provided by an expected bearer, and the MBR is a maximum bit rate that the bearer can provide, and may be used to limit a data transmission rate of a packet.
In the embodiment of the present application, in the correspondence relationship between bearers and QoS parameters, a first bearer corresponds to a set of QoS parameters, that is, a bearer corresponds to a set of QoS parameters. For example, bearer 1 corresponds to QoS parameter 1, bearer 2 corresponds to QoS parameter 2, GBR contained in QoS parameter 1 is G1, GBR contained in QoS parameter 2 is G2, bearer 2 is expected to be transmitted at a guaranteed transmission rate of G2 during t1, and bearer 1 is expected to be transmitted at a guaranteed transmission rate of G1 during t 2. For ease of description, in the embodiments of the present application, transport bearer means transport of a packet mapped to a bearer, for example transport bearer 1 means transport of a packet mapped to bearer 1, and so on.
A set of QoS parameters may also correspond to at least two bearers, where the at least two bearers include the first bearer, that is, a set of QoS parameters is set corresponding to the at least two bearers, and the at least two bearers need to transmit according to the QoS parameter requirements during transmission, and the sum of the QoS requirements of the at least two bearers must not exceed the specified range of the QoS parameters. For example, bearer 1 and bearer 2 correspond to QoS parameter 1, GBR contained in QoS parameter 1 is G1, MBR is M1, and transmission rate 1 when bearer 1 is transmitted alone in t1 period should satisfy: g1 ≦ Transmission Rate 1 ≦ M1, and Transmission Rate 2 when bearer 2 alone is transmitted during t2 should satisfy: g1 is less than or equal to transmission rate 2 is less than or equal to M1, and transmission rate 3 when bearer 1 and bearer 2 are jointly transmitted in t3 period should satisfy: g1 is less than or equal to transmission rate 3 is less than or equal to M1, namely the sum of the two transmission rates is not lower than G1 and not higher than M1.
The first bearer may also correspond to at least two sets of QoS parameters, that is, one bearer corresponds to at least two sets of QoS parameters, at least two sets of QoS parameters may correspond to time periods, and the bearer may transmit according to different parameter requirements at different time periods. For example, bearer 1 corresponds to QoS parameters 1 and 2, where the GBR included in QoS parameter 1 is G1, the GBR included in QoS parameter 2 is G2, bearer 1 is expected to be transmitted at the guaranteed transmission rate of G1 during t1, and bearer 1 is expected to be transmitted at the guaranteed transmission rate of G2 during t 2.
At least two bearers may correspond to at least two sets of QoS parameters, where the at least two bearers may include a first bearer, such as: in an optional manner, at least two bearers correspond to GBRs in at least two sets of QoS parameters one to one, and at least two bearers correspond to MBRs in one set of QoS parameters, that is, at least two bearers correspond to aggregated MBRs (aggregated MBRs, AMBRs). For example, the GBR corresponding to bearer 1 is G1, the GBR corresponding to bearer 2 is G2, and the AMBR parameter corresponding to bearer 1 and bearer 2 is M3, which means that when bearer 1 and bearer 2 coexist in a certain period of time, the sum of the transmission rates provided by the network to the two bearers does not exceed M3.
In another optional manner, when the at least two bearers are separately transmitted, the GBRs in the at least two sets of QoS parameters are in one-to-one correspondence, and when the at least two bearers are jointly transmitted, the Aggregated GBR (AGBR) in the set of QoS parameters is in correspondence, that is, the at least two bearers correspond to the AGBR. For example, the GBR for bearer 1 is G1, the GBR for bearer 2 is G2, and the AGBR parameter for bearer 1 and bearer 2 is G3, which means that when bearer 1 and bearer 2 coexist in a certain period of time (e.g. t3 in fig. 12 d), the sum of guaranteed transmission rates provided by the network to the two bearers is G3.
In embodiments of the present application, a bearer may be uniquely characterized by a bearer identifier, where the bearer identifier may be used to identify a bearer, and when the bearer is characterized by the bearer identifier, the correspondence between the at least one set of QoS parameters and the at least one bearer may be replaced by a correspondence between the at least one set of QoS parameters and the at least one bearer identifier, such as: one bearer identifier corresponds to one set of QoS parameters, or one bearer identifier corresponds to at least two sets of QoS parameters, or at least two bearer identifiers correspond to one set of QoS parameters, or at least two bearer identifiers correspond to at least two sets of QoS parameters.
The bearer not only corresponds to a bearer rate parameter, but also corresponds to other parameters or configurations, such as: the bearer may also be configured to correspond to a Traffic Flow Template (TFT), which is used to map the data packet to the bearer, and in a possible manner, a downlink traffic flow template configured at the gateway device and corresponding to the bearer includes part or all of the following information: the source IP is an IP address of network equipment (such as an FCC server), the destination IP is an IP address of terminal equipment, or the destination IP is a multicast IP address; the uplink service flow template configured at the terminal equipment and corresponding to the bearer contains part or all of the following information: the source IP is the IP address of the terminal device and the destination IP is the IP address of the network device (e.g., FCC server).
Step 2003: and the gateway equipment receives a data packet and maps the data packet to the first bearer according to the TFT.
The gateway device may receive data packets from a network device such as a server, router, or the like.
The gateway device that the TFT maps the data packet to the first bearer may include: the gateway device maps the received data packet which meets the packet filtering rule to the first bearer according to the packet filtering rule contained by the TFT (for example, when all or part of the IP quintuple information of the data packet meets a preset condition (for example, the destination IP address is a designated address, the port number is in a designated range, and the protocol type is TCP). It should be noted that, in the embodiment of the present application, a data packet that does not satisfy the packet filtering rule may be mapped onto a default bearer, or the data packet may be discarded or cleared.
Step 2004: and the gateway equipment sends the data packet to access network equipment through the first bearer by using the burst QoS parameter according to the indication information and the corresponding relation between the bearer and the QoS parameter.
And the gateway equipment determines the QoS parameters corresponding to the first bearer according to the corresponding relation between the bearers and the QoS parameters, determines the burst QoS parameters in the QoS parameters corresponding to the first bearer according to the indication information, and sends the data packets to the access network equipment through the first bearer by using the burst QoS parameters.
For example, in the embodiment of the present application, a data packet corresponding to a certain live program 1 of an IPTV belongs to a certain service data stream, and at a UPF, the data packet of the program 1 is mapped onto a certain bearer (for example, bearer 1) according to a packet filtering rule in a TFT, and is sent to an access network device, and then is sent to a terminal device by the access network device, so that a QoS requirement of the data packet of the program 1 in a transmission process is ensured.
Step 2005: and the access network equipment receives the data packet and sends the data packet to the terminal equipment through a second bearer according to the QoS parameters required by the service corresponding to the data packet according to the corresponding relation between the bearer and the QoS parameters.
The service corresponding to the data packet is a burst service or a non-burst service, and the QoS parameter required by the service corresponding to the data packet is one set of QoS parameter in the QoS parameters corresponding to the first bearer.
The correspondence between the bearer and the QoS parameter is obtained by the access network device from a management device (e.g., MME) and stored locally, and the correspondence between the bearer and the QoS parameter may refer to the above description, which is not described herein again.
Optionally, the data packet received by the access network device includes information indicating the first bearer and information used for indicating a QoS parameter required by a service corresponding to the data packet; or, the access network device is further configured to receive information indicating the first bearer and information indicating a QoS parameter required by a service corresponding to the data packet; the information indicating the first bearer may be a first bearer identifier for identifying the first bearer, and the information indicating the QoS parameter required by the service corresponding to the data packet may be: the QoS parameter may be a burst QoS parameter or a set of non-burst QoS parameters, or information indicating whether a service corresponding to the data packet is a burst service, or information indicating a certain set of parameters corresponding to the data packet, such as a QoS parameter identifier.
Optionally, the sending, by the access network device, the data packet to the terminal device through the second bearer according to the QoS parameter required by the service corresponding to the data packet according to the correspondence between the bearer and the QoS parameter includes: the access network device determines, according to information indicating a first bearer, for example, a first bearer identifier, that the data packet corresponds to the first bearer, maps the data packet to a second bearer according to a mapping relationship between the first bearer and the second bearer, where the second bearer is an air interface bearer RB, determines, according to information indicating a QoS parameter required by a service corresponding to the data packet, a QoS parameter required by the service corresponding to the data packet, and sends the QoS parameter to the terminal device through the RB according to the QoS parameter.
The mapping relationship between the first bearer and the second bearer may be determined by the access network device and stored locally, for example, the access network device determines according to the QoS parameter corresponding to the first bearer and the QoS parameter of the second bearer, such as: the access network device may determine, according to a corresponding relationship between a first bearer identifier and a QoS parameter in the QoS configuration information, or according to a corresponding relationship between a first bearer identifier and a QoS parameter of a preset standard, a QoS parameter corresponding to the first bearer identifier carried by the data packet, that is, a QoS parameter corresponding to the first bearer represented by the first bearer identifier, select or establish, according to the QoS parameter corresponding to the first bearer, a second bearer that can meet a QoS parameter requirement of the first bearer, and form a mapping relationship between the selected or established second bearer and the first bearer.
Thus, in the scheme shown in fig. 20, a suitable bearer can be determined according to the QoS requirement of the data packet, and the data packet is sent to the terminal device through the bearer, thereby ensuring the transmission of the data packet.
As an inverse process of sending the data packet, the embodiment of the present application further provides a technical scheme for uplink sending of the data packet, which is specifically shown in fig. 21.
Step 2101: the access network device stores the QoS configuration information.
The QoS configuration information may include a corresponding relationship between a bearer and a QoS parameter, and specifically, the QoS configuration information may refer to the description in the scheme shown in fig. 20, and is not described herein again.
Step 2102: and the terminal equipment sends the data packet to the access network equipment through the second bearer.
The second bearer may be an air interface bearer.
Step 2103: and the access network equipment receives the data packet and sends the data packet to the gateway equipment through the first bearer according to the QoS parameters required by the service corresponding to the data packet according to the corresponding relation between the bearer and the QoS parameters.
The service corresponding to the data packet is a burst service or a non-burst service, and the QoS parameter required by the service corresponding to the data packet is one set of QoS parameter in the QoS parameters corresponding to the first bearer.
The corresponding relationship between the first bearer and the QoS parameter may be obtained by the access network device from the management device.
The corresponding relationship between the first bearer and the QoS parameter can refer to the related description in the scheme shown in fig. 20, and is not described herein again.
Optionally, the sending, by the access network device, the data packet to the gateway device through the first bearer according to the QoS parameter required by the service corresponding to the data packet according to the correspondence between the first bearer and the QoS parameter includes: the access network equipment determines that a data packet received by the access network equipment corresponds to a first bearer according to the mapping relation between the first bearer and a second bearer, determines a QoS parameter corresponding to the first bearer according to the corresponding relation between the first bearer and the QoS parameter, and sends the QoS parameter to the gateway equipment through the first bearer.
Specifically, the mapping relationship between the first bearer and the second bearer may refer to the related description in fig. 20, and is not described herein again.
Step 2104: and the gateway equipment receives the data packet sent by the access network equipment through the first bearer and sends the data packet to the network equipment.
The network device may be a server, a router, a gateway, etc.
Thus, in the scheme shown in fig. 21, when the terminal device sends a data packet to the network device, that is, when the data packet is sent uplink, the data packet is sent to the network device through the first bearer according to the quality of service requirement of the data packet, which ensures the transmission of the data packet.
Optionally, in any of the schemes shown in fig. 20 and fig. 21, the access network device further receives bearer configuration information from the management device, where the bearer configuration information includes a corresponding relationship between a bearer identifier and a QoS parameter and second indication information, where the corresponding relationship between the bearer identifier and the QoS parameter is used to indicate the corresponding relationship between the bearer and the QoS parameter, one bearer identifier is used to characterize one bearer, the corresponding relationship between the bearer identifier and the QoS parameter at least includes a corresponding relationship between a first bearer identifier and at least one set of QoS parameters, the first bearer identifier is used to characterize the first bearer, and the second indication information is used to indicate a burst QoS parameter corresponding to the burst traffic flow in the QoS parameter corresponding to the first bearer identifier; or, the bearer configuration information includes a corresponding relationship between the first bearer identifier and at least one set of QoS parameters, or the corresponding relationship between the first bearer identifier and at least one set of QoS parameters and information indicating that the first bearer is used for sending the burst service flow, or the corresponding relationship between the first bearer identifier and at least one set of QoS parameters and information indicating that the first bearer corresponds to the burst QoS parameters, or the bearer configuration information includes a corresponding relationship between the first bearer identifier and at least one set of QoS parameters, information indicating that the first bearer is used for sending the burst service flow, and information indicating that the first bearer corresponds to the burst QoS parameters, where the first bearer identifier is used for representing the first bearer.
Optionally, in order to improve the admission capability of the system, in consideration of the necessity of bearer establishment, in any scheme illustrated in fig. 20 and 21, the gateway device activates the bearer, or the burst QoS parameter corresponding to the bearer and the bearer under a fifth preset condition. The fifth preset condition is as follows: the gateway equipment receives a request message which is sent by the terminal equipment and used for requesting the burst service flow; or, the gateway device receives a bearer resource modification request message from the terminal device; or, the gateway device receives the data packet of the burst service flow.
For example, the gateway device activates the bearer and/or its corresponding burst QoS parameters when either of the following conditions exists.
Case 1: when the gateway device receives a request message for requesting the network device to send the burst service stream from the terminal device, the bearer and/or the corresponding burst QoS parameter thereof are/is activated.
In one possible scenario, the network device may be an FCC server, the request message may be a zapping request message sent by the terminal device, the gateway device may parse the message sent by the terminal device, or determining that the message sent by the terminal device is a fast zapping request message according to part or all of the IP quintuple information contained in the message (for example, the gateway device is pre-configured with IP address information of an FCC server, and if the gateway device receives a data packet with a source address of the IP address of the terminal device, such as a CPE, and a destination address of the IP address of the FCC server for the first time within a period of time, it is determined that the data packet is a fast channel switching request sent by the CPE to the FCC server), fast channel switching is to be performed between the terminal device and the FCC server, and a unicast service stream rapidly pushed to the terminal device by the FCC server in the fast channel switching process is a burst service stream.
Case 2: when the gateway device receives the bearer resource modification request message from the terminal device, the bearer and/or the corresponding burst QoS parameter thereof are/is activated.
In one possible scenario, when a terminal device (e.g., a CPE) receives a fast zapping request sent by a set-top box, or the terminal device receives a response packet from a network device, or the terminal device receives a burst traffic stream from the network device, a bearer resource modification request message is sent to a gateway device, and after receiving the bearer resource modification request message, the gateway device activates a bearer and/or a corresponding burst QoS parameter.
Wherein, the sending, by the terminal device, the bearer resource modification request message to the gateway device may include: the terminal device sends a bearer resource modification request message to an MME through a non-access stratum (NAS) signaling message, and the MME sends a bearer resource modification request message to the gateway device, for example, the MME sends a bearer resource modification request message to an SGW, and the SGW sends a bearer resource modification request message to a PGW.
Case 3: when the gateway device receives a data packet of a burst traffic flow from the network device, the bearer and/or its corresponding burst QoS parameter are activated.
In an alternative mode, the network device is an FCC server, the data packet from the FCC server includes a response message of the zapping request to the terminal device, such as real-time transport control protocol (RTCP) messages, the gateway device determines the amount of data to be transmitted by the FCC server by parsing packets sent by the FCC server, or determining that the data packet carries a fast zapping response message sent by the FCC server to the terminal device according to IP quintuple information in the data packet (for example, the gateway device is pre-configured with IP address information of the FCC server, the gateway device receives the data packet 2, the source address of the data packet is the IP address of the FCC server, the destination address is the IP address of the terminal device such as the CPE, and if the data packet 1 sent by the CPE to the FCC server passes before, it can be determined that the data packet 2 contains the fast zapping response message sent by the FCC server to the CPE).
In another alternative, the network device is an FCC server, and the data packet from the FCC server includes a unicast data packet sent by the FCC server to the terminal device. For example, if the gateway device receives a unicast data packet sent to the terminal device by the FCC server for the first time within a period of time, and at this time, a bearer for a data packet related to fast zapping is not established with the terminal device, the gateway device establishes a bearer with the terminal device, and a unicast service stream for fast zapping is carried through the bearer; or, the gateway device receives a unicast data packet sent by the FCC server to the terminal device for the first time within a period of time, may select a QoS parameter meeting the requirement of the fast channel switching service for the existing bearer, and notifies the access network device of the change condition of the QoS parameter of the existing bearer through the MME.
Optionally, in order to ensure transmission of a burst service stream (e.g., interactive signaling and unicast data stream between an FCC server and a terminal device), the QoS parameter corresponding to the bearer may include: the first QoS parameter corresponding to the burst service flow is set according to the QoS requirement corresponding to the burst service flow, and the burst service flow may be a unicast data flow issued by an FCC server.
The first QoS parameter may include: the first GBR, optionally, further comprises a first MBR.
For example, in an alternative mode, the first GBR is x times the multicast rate (x is a real number equal to or greater than 1 and equal to or less than 2), and the first MBR is 2 times the multicast rate; alternatively, the first GBR is the FCC unicast up-rate transmission rate, the first MBR is min { FCC unicast up-rate transmission rate, FCC unicast down-rate transmission rate + multicast transmission rate }, where "min { }" represents the minimum value in the set.
The multicast rate may be measured by a terminal device, an access network device, or a gateway device, and the rate x of speeding up and/or the FCC unicast speeding up and sending rate and/or the FCC unicast slowing down and sending rate may be obtained by interaction between a management device (e.g., PCRF) and a network device (e.g., an FCC server), or obtained by interaction between a terminal device and a network device, or obtained by interaction between a network device and a gateway device.
In this way, in a possible manner, when the gateway device receives a burst traffic flow from the network device, the gateway device maps a data packet of the burst traffic flow to an existing bearer, selects a first QoS parameter for the bearer, and sends the burst traffic flow to the terminal device.
The selecting, by the gateway device, the first QoS parameter, and sending the burst service stream to the terminal device may include: the gateway equipment sends burst service flow to the access network equipment according to the first QoS parameter, the access network equipment receives the burst service flow, the QoS parameter is adjusted to bear the corresponding first QoS parameter, and the burst service flow is sent to the terminal equipment according to the first QoS parameter.
The adjusting, by the access network device, the parameter corresponding to the bearer to the first QoS parameter corresponding to the bearer may include: when the gateway device receives a burst traffic flow from the network device, the gateway device sends indication information (e.g., a bearer parameter switching indication) to the access network device, so as to notify the access network device to select a QoS parameter (e.g., a first QoS parameter) meeting the demand of the burst traffic flow for a certain bearer (e.g., bearer 1); after receiving the indication information, the access network device activates bearer 1, or adjusts a parameter corresponding to bearer 1 to a first QoS parameter, or activates bearer 1 and selects the first QoS parameter for bearer 1.
The indication information (taking the bearer parameter switching indication as an example) sent by the gateway device to the access network device may include: the gateway equipment sends information containing bearing parameter switching instructions to the MME, and then the MME sends the information containing the bearing parameter switching instructions to the access network equipment through an S1 interface; or the gateway device carries the bearer parameter switching instruction in a data packet of the user plane, for example, in a header corresponding to a general packet radio service tunneling protocol (GTP) layer or a User Datagram Protocol (UDP) layer or an IP layer, and sends the bearer parameter switching instruction to the access network device. Optionally, the bearer parameter switching indication includes a bearer identifier, and the specific QoS parameter after switching or the indication information of which set of QoS parameter corresponding to the bearer identifier is switched to, where the bearer identifier is used to identify the bearer corresponding to the data packet.
In order to avoid reducing the admission capacity of the network, in any of the schemes shown in fig. 20 and fig. 21, when there is no need to send a burst traffic flow for a long period of time, a bearer or a burst QoS parameter corresponding to the bearer is deactivated, that is, a bearer established for the burst traffic flow or a burst QoS parameter corresponding to the demand of the burst traffic flow in a given bearer is removed/deleted/deactivated.
Optionally, the gateway device deactivates the bearer, or the bursty QoS parameter corresponding to the bearer, or the bearer and the bursty QoS parameter corresponding to the bearer under a sixth preset condition. The sixth preset condition is that: the gateway equipment receives an end instruction for indicating the end of the burst service flow; or, the gateway device determines that a timer corresponding to the burst service flow is overtime; or, the gateway device receives a message for indicating to deactivate the bearer for sending the burst traffic flow.
For example, if the burst QoS parameter corresponding to the bearer is the first QoS parameter, when the gateway device receives a burst service end instruction sent by the network device, the bearer is deactivated or the first QoS parameter of the bearer is deactivated according to the burst service end instruction. The burst service ending indication is used for indicating that the network equipment is about to end the burst service flow or reducing the requirement of the burst service flow.
In a possible scenario, the network device is an FCC server, the gateway device is a PGW, and the burst service end indication may be, for example, a unicast multicast synchronization notification message sent by the FCC server, or, for example, a unicast stream end indication sent by the FCC server after sending out the last unicast packet. The gateway device may deactivate the bearer according to the burst service end indication or the first QoS parameter of the bearer may refer to: the gateway device receives the burst service end indication as a trigger condition for the gateway device to deactivate the bearer or the first QoS parameter of the bearer, that is, when the gateway device receives the burst service end indication sent by the network device, the gateway device deactivates the bearer or the first QoS parameter of the bearer.
In another embodiment of the present application, a timer set in the gateway device corresponding to the bursty traffic flows expires, and the gateway device deactivates the bearer or the first QoS parameter of the bearer, where the timer in the gateway device is used to define an effective time for the gateway device to receive the bursty traffic flows from the network device (e.g., an FCC server).
In another embodiment of the present application, the gateway device receives a deactivation request message from the terminal device or the access network device, deactivates the bearer or the first QoS parameter of the bearer according to the deactivation request message, wherein the deactivation request message is used for requesting the gateway device to deactivate the bearer established for the burst traffic flow or to deactivate a first QoS parameter corresponding to the burst traffic flow requirement of a given bearer, the given bearer is a bearer mapped by a burst service flow, the deactivation request message is a message sent after a timer in the terminal equipment or the access network equipment is overtime, or the terminal device receives a message sent by the network device after the burst service end indication is received, the timer in the terminal device is used for limiting the effective time of the terminal device for receiving the burst service flow sent by the network device, and the timer in the access network device is used for limiting the effective time of the access network device for receiving the burst service flow sent by the network device.
In a feasible manner, the deactivating of the bearer or the first QoS parameter of the bearer by the gateway device includes sending a message to a management device (e.g., MME) and an access network device, notifying the management device and the access network device to deactivate the bearer or deactivate the first QoS parameter of the bearer, after the access network device completes the deactivation of the bearer or the first QoS parameter of the bearer, sending a response message to the management device, the management device deleting the context of the bearer or deactivating the first QoS parameter in the context of the bearer, and then sending a response message to the gateway device by the management device, after receiving the response message, the gateway device may delete the context of the bearer or deactivate the first QoS parameter in the context of the bearer. The first QoS parameter for deactivating the bearer may refer to a procedure of deactivating the bearer by the gateway device, where the notification message sent to the management device and the notification message sent to the access network device carry the identifier of the bearer and the indication of the QoS parameter to be deactivated. It should be noted that, when the bearer only corresponds to the first QoS parameter, deactivating the first QoS parameter means deactivating the bearer.
The bearer may correspond to a second QoS parameter and other QoS parameters in addition to the first QoS parameter, that is, the bearer may correspond to multiple sets of QoS parameters at different time intervals. For example, the first QoS parameter may correspond to a fast channel switching service unicast fast push requirement, the second QoS parameter may correspond to a requirement for multicast transmission of a live program, and any of the schemes described in fig. 20 and 21 may further include the following.
The gateway device receives a burst service end indication sent by the network device, or receives a deactivation request message corresponding to a burst service stream from the terminal device or the access network device, or a timer corresponding to the burst service stream in the gateway device is overtime, and the gateway device deactivates a bearer for sending the burst service, or switches a QoS parameter corresponding to the bearer for sending the burst service from a first QoS parameter to a second QoS parameter. For example, optionally, the gateway device sends a bearer parameter switching indication to the management device and/or the access network device, where the bearer parameter switching indication corresponds to the first bearer, and the bearer parameter switching indication is used to notify the management device and/or the access network device to deactivate the first bearer; or, notifying the management device and/or the access network device to deactivate the first bearer and the first QoS parameter corresponding to the first bearer; or, the management device and/or the access network device are notified to deactivate a first QoS parameter corresponding to the first bearer and activate a second QoS parameter corresponding to the first bearer. So that the management device and/or the access network device will deactivate the first bearer according to the bearer parameter switching indication; or deactivating the first bearer and a first QoS parameter corresponding to the first bearer; or, the burst QoS parameter corresponding to the first bearer (i.e., the first QoS parameter) is deactivated and the second QoS parameter corresponding to the first bearer is activated.
The management device is a PCRF, the gateway device is a PGW, the network device is an FCC server, the terminal device includes a set-top box and a CPE, and there are two IPTV live channels watched by the user: the scheme shown in fig. 20 is described with respect to channels 1 and 2, where the QoS requirements of the multicast streams for the two channels are the same.
The PGW acquires a PCC rule containing QoS parameters related to services from the PCRF, wherein the QoS parameters contain GBR, the PGW establishes a bearer with terminal equipment (CPE) according to the acquired QoS parameters, and the corresponding relation between the bearer and the QoS parameters is as follows: bearer 1 corresponds to QoS parameter 1 and QoS parameter 2, GBR included in QoS parameter 1 is G1, and GBR included in QoS parameter 2 is G2, G2> G1. The data packets of the multicast transmission channel 1 and the channel 2 are both mapped to the bearer 1, and the corresponding QoS parameter is the QoS parameter 1, and the QoS parameter 2 is the burst QoS parameter, which is suitable for the unicast transmission mode of fast channel switching.
At a certain moment, a user sends a channel switching command to the set top box through a remote controller to request to switch from a channel 2 to a channel 1, and if the requested channel 1 supports fast channel switching, the set top box sends a message of requesting a target channel 1 program stream to the FCC server through the CPE. After receiving a message requesting a program stream of a target channel 1, an FCC server quickly sends the program stream corresponding to the channel 1 to a PGW in a unicast manner, when the PGW receives a unicast data packet corresponding to fast channel switching, the PGW determines that the program stream is a burst service, and needs to map the burst service to a bearer 1, and adjusts a parameter corresponding to the bearer 1 to a QoS parameter 2, and the PGW sends a bearer parameter switching instruction to an access network device through an MME, so as to instruct the access network device to adjust the parameter of the bearer 1 to the QoS parameter 2. After receiving the bearer parameter switching instruction, the access network equipment adjusts the parameter of the bearer 1 to the QoS parameter 2, sends the data packet of the channel 1 from the FCC server to the CPE at a higher guaranteed rate, and then the CPE sends the data packet to the set-top box, so that the user can see the program of the channel 1 more quickly.
In another feasible scheme, the terminal device may negotiate a packet forwarding rate with a network device (e.g., an FCC server) according to the capability of the access network device, so as to avoid a problem of buffer overflow or packet loss caused by the fact that the packet forwarding rate of the network device exceeds the sending capability of the access network device, so as to guarantee transmission of the service flow. The specific scheme is as follows.

Fig. 31 is a flowchart of another service transmission method provided in this embodiment, where the method may be applied to the 5G network shown in fig. 2a or the 4G network shown in fig. 2b to implement data packet transmission through rate negotiation.
Step 3101: the terminal device sends an inquiry message to the access network device.
The query message may be used to query the scheduling capabilities of the access network device (e.g., the guaranteed rate that the access network device may provide).
Step 3102: the access network equipment receives the inquiry information from the terminal equipment and sends a response message to the terminal equipment according to the inquiry information.
The response message may include information (e.g., guaranteed rate information) for indicating scheduling capability of the access network device, and the sending, by the access network device, the response message to the terminal device according to the inquiry message may refer to: the access network equipment receives the inquiry message as a trigger condition for the access network equipment to send a response message to the terminal equipment, and when the access network equipment receives the message for inquiring the scheduling capability, the access network equipment sends the response message to the terminal equipment.
The guaranteed rate information may include: the transmission rate supportable by the access network device. The guaranteed rate can be obtained by the access network equipment according to the cache state of the access network equipment, system bandwidth resources, the number of users in the cell and/or service priority and other information.
Step 3103: and the terminal equipment receives the response message from the access network equipment and sends the reference sending rate to the network equipment.
The reference sending rate is determined according to the guaranteed rate information in the response message, and provides a reference basis for the rate when the network device sends the data packet, such as: the guaranteed rate information may include a maximum transmission rate supported by the access network device, and the reference transmission rate may not exceed the maximum transmission rate when determined.
In a possible scenario, the network device is an FCC server, and the reference sending rate may be carried by the terminal device in a request message and sent to the network device, or the reference sending rate may be carried in a message different from the request message and sent to the network device, which is not limited in this application embodiment, where the request message may be a message for requesting the network device to issue a data packet, and the request message may be an RTCP message, for example: the fast zapping request message may include a target channel identifier, and is used to request the network device to send a program stream of the target channel.
Optionally, the terminal device sends the reference sending rate to the network device through network elements such as the access network device and the gateway device.
Step 3104: the network equipment receives the reference sending rate and sends the data packet to the terminal equipment at the first rate according to the reference sending rate.
The first rate is determined according to a reference transmission rate, and if the first rate is determined not to exceed the reference transmission rate, the first rate may be equal to or less than the reference transmission rate.
It should be noted that, when the data packet requested to be sent by the terminal device is not cached in the network device, the step 3104 is not executed, but the network device sends a response message to the terminal device to notify that the request processing of the terminal device fails; otherwise, step 3104 above is performed.
Thus, in the scheme shown in fig. 31, the terminal device may negotiate the rate of transmitting the data packet according to the capability of the access network device and the network device, transmit the data packet according to the negotiated rate, and ensure the transmission of the data packet under the condition of adapting to the transmission capability of the access network device.
Further optionally, in the process of executing the scheme shown in fig. 31, if the air interface capability between the access network device and the terminal device changes, the access network device sends updated guaranteed rate information to the terminal device; the terminal device receives the updated guaranteed rate information from the access network device, and sends an updated reference sending rate to the network device according to the updated guaranteed rate information, wherein the updated reference sending rate is determined according to the updated guaranteed rate information, and the steps are as follows: the updated guaranteed rate information may include an updated maximum transmission rate supported by the access network device, and the updated maximum transmission rate may not be exceeded when the reference transmission rate is updated.
And the network equipment receives the updated reference sending rate from the terminal equipment and issues a data packet to the terminal equipment at a second rate according to the updated reference sending rate.
Wherein the second rate is determined according to the updated reference sending rate, such as: the second rate, when determined, cannot exceed the updated reference sending rate, i.e., the second rate may be less than or equal to the updated reference sending rate.
In another feasible scheme, the data packet sent by the network device may also be cached to the local device, and the local device sends the data packet requested by the terminal device to the terminal device, so as to improve the efficiency of the terminal device in obtaining the data packet. The specific scheme is as follows.
