Description

The present invention claims to be submitted to the Chinese Patent Office on April 25, 2012, the application number is 201210123596. 5, the priority of the Chinese patent application entitled "Alarm Information Transmission Method and Apparatus", the entire contents thereof This is incorporated herein by reference. Technical field

The present invention relates to the field of wireless communications, and in particular, to a method and device for transmitting alarm information. Background technique

Machine-type communication (MTC) communication is a new communication concept. Its purpose is to combine many different types of communication technologies, such as: machine-to-machine communication, machine control communication, human-computer interaction communication, mobile Connected communications to promote social production and lifestyle development. It is expected that the business of human-to-human communication in the future may only account for 1/3 of the entire terminal market, and a larger amount of communication is the MTC communication service. Sometimes, MTC communication is also known as machine-to-machine (M2M) communication or the Internet of Things.

Current mobile communication networks are designed for communication between people, such as the determination of network capacity. If it is desired to utilize the mobile communication network to support MTC communication, it is necessary to optimize the mechanism of the mobile communication system according to the characteristics of the MTC communication, so that it can be better in the case where the traditional human-to-human communication is not affected or less affected. Implement MTC communication.

Some of the features that are currently recognized for MTC communication are:

- MTC terminals have low mobility;

- The time for data transmission between the MTC terminal and the network side is controllable; - The data transmission performed by the MTC terminal and the network side does not require high real-time data transmission, that is: time tolerance;

- MTC terminals are energy limited and require very low power consumption;

- only small amount of information transmission between the MTC terminal and the network side;

- MTC terminals can be managed in groups;

- The MTC terminal can report in real time in case of theft or man-made damage

An actual MTC terminal can have one or more of the features described above.

There is currently no known solution for transmitting MTC device alarm information. If the normal service transmission mode is used, that is, the alarm information is reported in the uplink user plane service, the alarm information will be delayed, and the network side cannot monitor the alarm information of the device in real time. At the same time, according to the current data transmission mode, After the DRB (Data Radio Bearer)/RB (Radio Bearer, Radio Bearer) and Sl/Iu bearer are established through the signaling process of the connection/bearer setup process, the data can be carried over the DRB/RB and Sl/Iu bearers. Send to the network side (for UMTS, you need to establish the corresponding SRB/RB, Iu/Iub and other bearers).

The amount of information of the alarm information is very small. Usually, there is only one indication information, and the signaling overhead required to transmit the alarm information is relatively large, thereby seriously reducing system efficiency. If it is transmitted on the user plane, it will consume more unnecessary signaling overhead. Summary of the invention

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of an MTC terminal reporting an alarm message in an Idle (idle) state in an LTE (Long Term Evolution) system according to an embodiment of the present invention. The network architecture of the LTE system usually includes an eNB (Evolved Base Station), an MME (Mobility Management Entity), an S-GW (Serving Network Gateway), and a P-GW (Packet Data Network Gateway). Data Gateway), HSS (Home Subscriber Server). The interface between the MTC terminal and the eNB is a Uu interface, and the interface between the eNB and the MME is an S1 interface.

In the Idle state, the MTC device may carry an alarm information indication in the RRC (Radio Resource Control) connection establishment complete message. After receiving the message, the eNB notifies the corresponding MME of the alarm information through the S1 interface protocol according to the obtained terminal information (for example, the registered PLMN or the MME). The S1 interface protocol can use existing messages plus alarm information or adopt newly defined S1 interface signaling. After receiving the alarm indication, the MME parses out the NAS PDU (non-access stratum packet data unit). The terminal identifier (terminal ID), and can locate the alarm that the terminal has occurred.

As shown in Figure 1, after the AS layer (that is, the application layer) of the MTC terminal receives the triggered alarm information, it first initiates a random access procedure and passes the random access process.

The RRC connection setup signaling sends an alert message to the eNB, and is sent by the eNB to the core network device through the S1 interface between the eNB and the core network device. The random access procedure may include: Step 101: When the MTC terminal needs to send the alarm information, firstly, according to the random access resource information configured by the system, wait for a random access channel (RACH) scheduling period, and select a preamble code to send to the eNB. (Msgl).

Step 102: After receiving the preamble (Msgl) sent by the MTC terminal, the eNB sends a random access response (Msg2) to the MTC terminal in the random access response window. A random access response message (Msg2) can respond to a random access request (preamble) of multiple terminals. The Msg2 is scheduled by the RA-RNTI (Radio Access-Radio Network Temporary Identity) DCI (Downlink Control Information), and the RA-RNTI is determined by the time-frequency resource location of the Msgl. The content in Msg2 includes: backoff parameter, preamble identifier corresponding to Msgl, uplink transmission timing advance (TA), Msg3 allocated uplink resource (Msg3 scheduling information), temporary C-RNTI (cell wireless network temporary identifier) ). The backoff parameter is used to indicate the average delay of the next random access initiated by the terminal if the random access fails. The terminal determines the random access response sent to itself by using the preamble identifier in the RA-RNTI and the Msg2. If the preamble corresponding to the preamble identifier in the Msg2 includes the preamble when the random access is initiated by itself, the terminal considers that it successfully receives the random access. In the response message, Msg3 will be sent to the network side. If the terminal does not correctly receive the Msg2, the delay of the next random access is determined according to the delay limit of the backoff parameter, and the random access resource is selected to initiate the next random access. After the maximum number of random accesses is reached, the terminal MAC (Media Access Control) layer reports to the RRC layer. Random access problem, triggering the wireless link failure process.

Step 103: After receiving the Msg2, the MTC terminal sends the Msg3 on the uplink resource allocated by the Msg2. In the initial access, the RRC connection re-establishment request message generated by the RRC layer is carried in the Msg3.

In step 104, the eNB and the MTC terminal complete the final contention resolution through the Msg4. The Msg4 content corresponds to the content of Msg3. During initial access, the carrying terminal in Msg4 competes to resolve the Contention Resolution Identity MAC CE, which contains the CCCH SDU (Common Control Channel Service Data Unit) transmitted by the terminal in Msg3, and the terminal receives After the MAC CE, it is compared with its own RRC layer information to complete the competition resolution. In addition, the Msg4 may include an RRC connection setup message for establishing a signaling radio bearer 1 (SRB1) of the terminal.

Step 105: After receiving the RRC connection setup message, the terminal adds an alarm indication to the RRC connection establishment complete message, and carries the initial NAS PDU, where the NAS PDU carries the ID information of the terminal.

Step 106: After receiving the alarm indication information reported by the terminal, the eNB transmits the alarm information of the terminal to the core network MME through the S1 interface signaling (NAS service request), and requests the MME to establish an eNB corresponding to the terminal. Related connections between core network elements (connected to the control plane of the MME and E-RAB with the radio access of the S-GW). After receiving the alarm information transmitted by the eNB, the MME parses the NAS PDU to obtain the terminal ID, and can locate the alarm information of the terminal.

Step 107: The MME notifies the eNB of the information about the connection of the terminal.

Step 108: The eNB sends a security mode command (SMC) and an RRC connection reconfiguration message to the terminal, which is used to activate the security of the terminal and establish a data radio bearer (DRB) and other signaling radio bearers (SBR2) for the terminal. It should be noted that the security mode command (SMC) and RRC connection reconfiguration can be sent in one RRC message, or separately. Send.

Step 109: After the security activation and the DRB and SRB2 configurations are completed, the terminal sends a security mode complete message and an RRC connection reconfiguration complete message to the network side.

Step 110: After the foregoing process, the user plane data of the terminal is carried by the DRB and the SI, and is sent to the core network by using the eNB and the S-GW. The control signaling of the terminal and the core network is between the SRB and the eNB and the MME. The control plane connection is sent to the MME.

Steps 101~104 and 107-110 in the above process are consistent with the existing random access procedure. If the terminal initiates the service information and initiates the service access request at the same time, the terminal suspends the service request and first sends the alarm information.

In the above process, the RRC connection setup complete message of the Uu interface in step 105, and the initial UE message of the S1 interface in step 106 may be added with the following IE (information unit) indication information:

The RRCConnectionSetupComplete-vxyO-IEs is a new IE that carries the alarm indication information of the MTC terminal.

Specifically, the S1 interface signaling may carry the alarm information in the Initial UE Message (initial user message) information unit, as shown in Table 1: Table 1. Initial UE Message information element format

The Priorityalarmindication is used to indicate the alarm information of the terminal.

The MTC terminal does not send an RRC connection setup complete message to the eNB in the connected state. Therefore, in the embodiment of the present invention, the terminal in the connected state newly defines a RRC alarm signaling (for example, PriorityAlarmlndication) on the Uu interface, where the terminal carries the alarm. Information, that is, the terminal reports its alarm information through the signaling. After receiving the alarm signaling, the eNB suspends the ongoing service communication of the terminal. First, the alarm information is notified to the MME through the S1 interface protocol (new signaling can be defined or existing signaling is used), because in the connection state, both the eNB and the MME can Identify the terminal ID. The alarm information reporting process may be as shown in FIG. 2, wherein the MTC terminal is in an RRC connection state. When the MTC terminal detects an alarm, the process may include:

Step 201: The RRC layer of the MTC terminal initiates RRC alarm signaling, and reports it to the eNB. Step 202: After receiving the alarm indication information reported by the terminal, the eNB transmits the alarm information of the terminal to the core network MME by using the S1 interface signaling on the S1 interface.

After receiving the alarm information, the MME may continue to submit the alarm information upward. This part is not within the scope of the embodiment of the present invention.

In the above process, the RRC alarm signaling in the step 201 is the signaling that is newly defined in the embodiment of the present invention, and the PriorityAlarmlndication in the signaling is used to carry the alarm indication information of the terminal, which is specifically:

Table 2. UE SPECIFIC PRIORITY ALARM INDICATION

The Priority alarm indication is used to indicate the alarm information of the terminal.

FIG. 3 is a schematic flowchart of reporting alarm information in an IDSL state of an MTC terminal in an Idle state in a Universal Mobile Telecommunications System (UMTS) provided by an embodiment of the present invention. The network architecture of the UMTS system usually includes NB (base station), RNC (Radio Network Controller, Wireless Network Controller), CN (Core Network, Core Network). The CN may include devices such as an MSC (Mobile Switching Center), an SGSN (Serving GPRS Support Node), and an HLR (Home Location Register). The interface between the MTC terminal and the NB is a Uu interface, and the interface between the RNC and the CN is an Iu interface.

In the Idle state, the MTC terminal may carry an alarm information indication in the RRC connection setup complete message. After receiving the message, the RNC passes the alarm information to the Iu based on the registered PLMN (Public Land Mobile Network) ID and CN domain carried in the Initial Direct Transfer message initiated by the terminal. The interface RANAP (Radio Access Network Application Part) protocol is delivered to the core network. The Iu interface protocol can use existing message plus alarm information or adopt newly defined Iu interface signaling. After receiving the alarm indication, the MSC/SGSN can resolve the NAS PDU to obtain the terminal ID, and can locate the alarm that the terminal has generated.

As shown in FIG. 3, after receiving the triggered alarm information, the AS layer of the MTC terminal first initiates a random access procedure, and sends an alarm message to the RNC through the RRC connection setup signaling in the random access procedure, and The RNC sends the core network device through its Iu interface with the core network device. The random access procedure can include:

Step 301: The MTC terminal sends an RRC Connection Request message on the uplink CCCH, requesting to establish an RRC connection. The main parameters carried in the message include: Initial UE Identity, Establishment cause, Protocol Error Indicator, and so on.

Step 302: The RNC sends an RRC Connection Setup message to the terminal on the downlink CCCH, for establishing an uplink transport channel, a downlink transport channel, a physical channel, a UL (uplink) radio resource, and a DL (downlink). ) Wireless resources, etc. Step 303: After receiving the RRC connection setup message, the MTC terminal adds an alarm indication (alarm indication) to the RRC Connection Setup Complete message, and sends the RRC Connection Setup Complete message to the RNC through the uplink DCCH. .

Step 304: The MTC terminal initiates an initial direct transmission message (carrying a NAS PDU), where the selected PLMN ID, the CN domain, and the like are carried.

Step 305: After receiving the initial direct transmission message, the RNC selects the Iu interface route according to the information such as the PLMN ID and the CN domain, and simultaneously transmits the alarm information reported by the terminal in the Initial UE Message. After receiving the alarm information transmitted by the RNC, the MSC/SGSN parses the NAS PDU to obtain the UE ID, and can locate the alarm information of the terminal.

Steps 301 to 302 and 304 in the above process are consistent with the existing random access procedure. If the terminal initiates the service information and initiates the service access request, the terminal suspends the service request and first sends the alarm information.

In the above process, the RRC connection setup complete message in step 303 carries the alarm information, and the specific signaling may be as shown in Table 3:

In the foregoing process, the Initial UE message in the Iu interface carries the alarm information in the step 305, and the content of the Initial UE message may be as shown in Table 4:

><

Table 4, Initial UE message:

The MTC terminal does not send a connection establishment complete message to the RRC in the connected state. Therefore, the embodiment of the present invention newly defines a dedicated RRC alarm signaling (for example, Priority Alarmlndication) on the Uu interface for the terminal in the connected state, where the terminal carries the terminal. Report Police information. After receiving the alarm signaling, the RNC suspends the ongoing service communication of the terminal. First, the alarm information is notified to the MSC/SGSN through the Iu interface protocol (you can define new signaling or use existing signaling), because it is in the connection state, RNC and The SGSN is able to identify the UEID. The alarm information reporting process is as shown in FIG. 4, where the MTC terminal is in an RRC connection state. When the MTC terminal detects an alarm, the process may include:

Step 401: The RRC layer of the MTC terminal initiates RRC alarm signaling, and reports the RRC alarm signaling to the RNC. Step 402: After receiving the alarm indication information reported by the terminal, the RNC transmits the alarm information of the terminal to the core network MSC/SGSN through the RANAP protocol signaling on the Iu interface.

After receiving the alarm information, the MSC/SGSN may continue to submit the alarm information, which is not within the scope of the embodiment of the present invention.

In the above process, the newly defined signaling PRIORITY ALARM INDICATION on the Uu interface in step 401 can be as shown in Table 5:

Table 5. PRIORITY ALARM INDICATION Signaling for Uu Interface

In the above process, the newly defined signaling UE SPECIFIC PRIORITY ALARM INDICATION on the Uu interface in step 402 can be as shown in Table 6:

Table 6. Newly defined signaling for the Iu interface UE SPECIFIC PRIORITY ALARM INDICATION

Through the above process, it can be seen that if the alarm information of the terminal is reported in the existing service transmission mode, that is, the alarm information is reported in the uplink user plane, the alarm information will be delayed, and the network side cannot monitor the alarm of the device in real time. At the same time, according to the current data transmission mode, the DRB/RB and S 1/Iu bearers need to be established through the signaling process before the data can be sent to the network side through the DRB/RB and Sl/Iu bearers. In the embodiment of the present invention, the alarm information reported by the terminal is completed through the RRC connection in the bearer establishment process, and the alarm information can be reported in time, and the signaling overhead and the air interface resource are also reduced.

The foregoing embodiment of the present invention is described by using an MTC terminal as an example. For other mobile communication terminals that have an alarm reporting requirement, the alarm information reporting mechanism provided by the embodiment of the present invention may also be used.
