Description

Method and device for paging

Technical field

This application relates to the communication field, and more specifically, to a method and device for paging in the communication field.

Background technique

With the development of communication technology, many terminal devices (such as mobile phones) have the function of supporting multiple subscriber identification module (SIM) cards. Taking the terminal device supporting two SIM cards as an example, there are many possible implementation methods, such as dual SIM single standby (DSSS) mode, dual SIM dual standby (DSDS) mode, or dual Card dual active (dual SIM dual active, DSDA) mode.

In the DSDS mode, the two SIM cards in the terminal device share a set of transceivers. For an idle terminal device, it is necessary to monitor the paging messages of the two SIMs. As an example, time division multiplexing (TDM) may be used to monitor paging messages. Specifically, a terminal device in an idle or inactive state needs to wake up at a certain time position in a certain period to monitor whether there is a paging on the network. This time position can be called the terminal equipment's Paging occasion (paging occasion, PO).

For the DSDS mode terminal device, it is possible that the time domain positions of the PO corresponding to the two SIM cards are the same or overlap, that is, there is a paging conflict. Since the terminal device can only monitor the paging message corresponding to one SIM on one PO, it may happen that the other SIM does not receive the paging message.

Therefore, there is an urgent need for a paging solution to solve the problem of how the terminal device in the DSDS mode performs paging when a paging conflict occurs.

Summary of the invention

The present application provides a paging method and device, which can help avoid page loss in DSDS mode terminal equipment.

In the first aspect, a paging method is provided, which is applicable to a terminal device, and the terminal device supports a first user identity. The method is executed by the terminal device or the chip in the terminal device. In the following, the method is executed by a terminal device as an example for description.

In this method, the terminal device determines that the first user identity includes a first paging occasion PO and a second PO within a paging cycle of the first user identity, and the first PO and the second PO are used to access the network The device pages the terminal device. Then, the terminal device listens to the paging message of the first user identity on the first PO or on the second PO as the first user identity.

Therefore, in the embodiment of the present application, the first PO and the second PO are set in a paging cycle of the first user identity of the terminal device, and the access network device sends a paging message on both the first PO and the second PO. , So that when the terminal device monitors the paging message as the first user, it can choose to monitor the paging message on the first PO or monitor the paging message on the second PO, thereby helping to avoid page loss, and further Yes, it helps to avoid missed call problems caused by page loss.

With reference to the first aspect, in some implementation manners of the first aspect, the terminal device further supports a second user identity, and the terminal device includes a third PO in a paging cycle of the second user identity.

When the time domain position of the first PO overlaps with the time domain position of the third PO, the terminal device uses the second user identity to monitor the search of the second user identity on the third PO. Paging message, the terminal device monitors the paging message of the first user identity on the second PO as the first user. or

When the time domain position of the second PO overlaps with the time domain position of the third PO, the terminal device uses the second user identity to monitor the search of the second user identity on the third PO. Paging message, the terminal device monitors the paging message of the first user identity on the first PO as the first user.

That is, when a conflict occurs, since the first user identity has two POs in a paging cycle, the paging of the second user identity can be monitored first, and the first user identity can be monitored on another PO that does not conflict with the first user identity. User identity paging, which can ensure that the paging messages of the two user identities will not be lost.

Or, when the time domain position of the first PO and the time domain position of the second PO do not overlap with the time domain position of the third PO, the terminal device is in the position of the first user as the first user. The first PO or the second PO monitors the paging message of the first user identity, and the terminal device uses the second user identity to monitor the second user identity on the third PO. Paging message.

For example, the terminal device listens to the paging message of the first user identity on the first PO and the second PO in the first PO as the first user identity, or the terminal device listens to the paging message of the first user identity as the first user identity according to the UE ID calculation. The paging message of the first user identity is monitored on that PO.

Therefore, in the embodiment of the present application, when the terminal device supports the first user identity and the second user identity, the first PO and the second PO are set in a paging cycle for the first user identity of the terminal device, so that In the case of possible paging conflicts between the identity of the first user and the identity of the second user, when the terminal device monitors the paging message with the identity of the first user, it can select the time of the PO in the paging cycle that does not have the identity of the second user. Monitoring on the PO conflicting on the domain resources can avoid the loss of paging messages in the user identity of the terminal device.

With reference to the first aspect, in some implementation manners of the first aspect, the time domain location of the first PO is determined according to the first user equipment identifier of the first user identity.

The time domain location of the second PO is determined according to the second user equipment identification of the first user identity, where the second user equipment identification is different from the first user equipment identification.

As an example, the first user equipment identification may be a user equipment identification assigned by the network to the terminal device when the terminal device is registered in the network as the first user. As an example, the second user equipment identity may be a user equipment identity that is different from the first user equipment identity of the first user identity that is additionally allocated by the core network device to the terminal device (that is, the first user identity is allocated by the core network device to two User equipment identification).

Alternatively, the time domain position of the second PO is determined according to the first user equipment identifier and the first offset value. The first offset value may be used to indicate the offset of the third user equipment identifier corresponding to the second PO relative to the first user equipment identifier. In other words, the first user equipment identification may be offset by the first offset value to obtain the third user equipment identification, and then the second PO may be determined according to the third user equipment identification. or

The time domain position of the second PO is determined according to the time domain position of the first PO and a second offset value, where the second offset value is used to indicate the time domain position of the second PO The offset relative to the time domain position of the first PO.

With reference to the first aspect, in some implementations of the first aspect, the second offset value includes at least one of a radio frame offset value, a subframe offset value, and a paging frame offset value.

With reference to the first aspect, in some implementations of the first aspect, the first user equipment identifier of the first user identity includes the temporary mobile user identification code S-TMSI of the first user identity. At the same time, the second user equipment identifier may also include S-TMSI.

With reference to the first aspect, in some implementations of the first aspect, the terminal device may also receive the second user equipment identifier from the core network device as the first user identity, or the first offset Value, or the second offset value.

In some possible implementations, the first offset value or the second offset value may be predefined. Exemplarily, the first offset value or the second offset value may be stored in the terminal device or the access network device in advance, or the first offset value or the second offset value may be defined by the protocol. This is not limited.

Therefore, in this embodiment of the present application, the terminal device may determine the second PO according to the foregoing second user equipment identifier, or the first offset value, or the second offset value.

In some possible implementations, the terminal device may send auxiliary information to the core network device as a user identity (such as the first user identity), and the auxiliary information is used to indicate the identity of the first user of the terminal device for determining paging The parameter of the timing, and/or the parameter of the second user identity of the terminal device used to determine the paging timing. After receiving the auxiliary information, the core network device may determine the above-mentioned second user equipment identifier, or the first offset value, or the second offset value according to the auxiliary information.

Therefore, the core network device can ensure based on the auxiliary information that the second PO derived based on the second user equipment identifier, or the first offset value, or the second offset value no longer conflicts with the PO of the second user identity, thereby Avoid the problem of paging message loss for the first user identity and the second user identity.

In a possible situation, when the terminal device supports at least two user identities, regardless of whether the two user identities may have a paging conflict, the terminal device sends the first indication information to indicate the terminal to the core network device The device supports at least two user identities.

Therefore, by sending the first indication information as the first user identity to the core network device under the condition that the terminal device supports at least two user identities, regardless of whether the paging of the at least two user identities conflict The network equipment is often notified whether it needs to send paging messages on at least two POs, so as to reduce the signaling overhead of the system and is easier to implement.

In a possible situation, when the terminal device determines that the time domain position of the PO of the first user identity overlaps with the time domain position of the PO of the second user identity of the terminal device, the terminal device is Sending the first indication information to the core network device by the first user identity.

Optionally, when at least two user identities of the terminal device no longer have a paging conflict, for example, after the terminal device changes a serving cell (for example, after performing a cell reselection), the terminal device may notify the core network device of its at least two users No more paging conflicts with identities. At this time, the access network device can restore the existing mechanism, that is, send a paging message on a PO in a paging cycle to reduce the consumption of paging resources.

Therefore, when the terminal device determines that the time domain position of the PO of the first user identity conflicts with the time domain position of the PO of the second user identity, the terminal device sends the first indication information as the first user identity to the core network device, so that the access network The device sends paging messages on at least two POs in a paging cycle, which can reduce the consumption of system paging resources.

Fig. 1 shows a schematic diagram of an application scenario of an embodiment of the present application. Figure 1 includes an access network device, a core network device, and a terminal device. Among them, the access network equipment, for example, works in an evolved universal mobile communication system terrestrial radio access (evolved UMTS terrestrial radio access, E-UTRA) system, or works in an NR system, or works in a next-generation communication system or other In the communication system. The core network equipment, for example, works in the E-UTRA system, or works in the NR system, or works in the next-generation communication system or other communication systems. In Figure 1, taking the core network equipment working in the 5G core network (5GC) as an example, the core network equipment and the access network equipment can communicate through the NG interface, and the access network equipment and the terminal equipment can communicate through the Uu interface. In the embodiments of this application, one access network device can serve multiple terminal devices. Figure 1 only takes one terminal device as an example. One core network device can also serve multiple access network devices. Take one of the access network equipment as an example.

Fig. 2 shows a schematic diagram of another application scenario of an embodiment of the present application. In FIG. 2, it includes an access network device 1, an access network device 2, a core network device 1, a core network device 2, and a terminal device. Figure 2 takes the radio access network (RAN) as an example. Core network equipment and access network equipment can communicate through NG interfaces, and access network equipment and access network equipment can communicate through NG interfaces. Xn interface communication. In addition, the Uu interface can be used to communicate between the access network device and the terminal device. Among them, these two access network devices, for example, work in the evolved UMTS terrestrial radio access (E-UTRA) system, or work in the NR system, or work in the next-generation communication system Or in other communication systems. These two core network devices, for example, work in the E-UTRA system, or in the NR system, or in the next-generation communication system or other communication systems.

The access network device in FIG. 1 or FIG. 2 is, for example, a base station. Among them, the access network equipment corresponds to different equipment in different systems. For example, in a 4G system, it can correspond to an eNB, and in a 5G system, it corresponds to an access network device in 5G, such as gNB. In the same way, core network equipment corresponds to different equipment in different systems. For example, in a 4G system, it can correspond to a mobility management entity (MME), and in a 5G system, it corresponds to a core network equipment in 5G, such as AMF. Of course, the technical solutions provided by the embodiments of this application can also be applied to future mobile communication systems. Therefore, the access network equipment in FIG. 1 or FIG. 2 can also correspond to the access network equipment and core network equipment in the future mobile communication system. The equipment can also correspond to the core network equipment in the future mobile communication system. Figure 1 or Figure 2 takes the access network device as a base station as an example. In fact, referring to the previous introduction, the access network device may also be a device such as an RSU.

In the embodiment of the present application, the terminal device supports at least one user identity, such as a first user identity and/or a second user identity. Here, "user identity" (for example, the first user identity or the second user identity, etc.) is a logical concept. For example, "user identity" can correspond to SIM card or subscriber information or virtual SIM card or user identity (such as international mobile subscriber identity (IMSI) or temporary mobile subscriber identity (TMSI), etc.) . From the perspective of the network side, different "user identities" logically correspond to different communication entities served by the network side, such as terminal devices in 4G and 5G systems. For example, a terminal device that supports two user identities can be regarded as two communication entities to the network side. For another example, when the "user identity" corresponds to the SIM card or subscriber information, the network side will recognize two terminal devices that support different SIM cards or different subscriber information as two different communication entities, and will also support multiple different communication entities. The same terminal device with SIM card or multiple subscriber information is identified as multiple different communication entities, even in reality, the terminal device supporting multiple different SIM cards or multiple subscriber information is just one physical entity.

Exemplarily, the SIM card can be understood as the key for the terminal device to access the mobile network. For ease of description, the SIM card and its evolution are collectively referred to as the SIM card in the embodiments of the present application. For example, the SIM card may be an identification card of a global system for mobile communications (GSM) digital mobile phone user, which is used to store the user's identification code and key, and support the authentication of the user by the GSM system. For another example, the SIM card may also be a universal subscriber identity module (USIM), which may also be referred to as an upgraded SIM card. In the embodiments of the present application, description will be made mainly by taking the "user identity" corresponding to the SIM card as an example.

In the embodiment of the present application, a SIM card is installed in the terminal device, and it is considered that the terminal device supports a user identity. For example, a terminal device with two SIM cards installed supports two user identities. In other words, there is a one-to-one correspondence between the SIM card and the user identity.

As an example, more and more smart phones currently support the insertion of two SIM cards at the same time. For example, one SIM card is used for private business and the other SIM card is used for work; or, one SIM card is used for data business. Another SIM card is used for voice services. Among them, the two SIM cards in a mobile phone can belong to the same mobile operator or different mobile operators; they can belong to the same standard (standards include NR, LTE, wideband code division multiple access, WCDMA ), time division multiple access (TDMA 2000, or GSM, etc.) can also belong to different standards.

According to the different transceiver capabilities of the terminal device, the terminal device with dual SIM cards can have one of the following three modes:

1. Passive mode, or also known as DSSS mode: Although two SIM cards can be inserted, only one can be used at a time.

Refer to Figure 3A, which is a schematic diagram of the passive mode. In Figure 3A, two SIM cards are respectively USIM1 and USIM2 as an example. At time 1, USIM1 is working (or in RRC connected state (connected)), that is, USIM1 can send and receive data, but USIM2 cannot be used at this time; or, at time 2, USIM2 is working (or in RRC connected state), also That is, USIM2 can send and receive data, but USIM1 cannot be used at this time.

2. DSDS mode: Two SIM cards share a set of transceivers. For the idle state, the transceiver needs to monitor the paging messages of the two cards. For example, the transceiver may use time division multiple (TDM) mode to monitor.

Refer to FIG. 3B, which is a schematic diagram of the DSDS mode. In Figure 3B, two SIM cards are respectively USIM1 and USIM2 as an example. At time 1, USIM1 is working (or in RRC connected state), that is, USIM1 can send and receive data. At this time, USIM2 can be in an idle state or inactive state (inactive); or, USIM2 is working (or in RRC connected state), That is, the USIM2 can send and receive data, and at this time, the USIM1 can be in an idle state or an inactive state. In this article, the inactive state can also be called the deactivated state, or the deactivated state, etc.

3. DSDA mode: Two SIM cards use their own transceivers. The two SIM cards can be in the RRC connection state at the same time, that is, the terminal device can receive and send data from the two SIM cards at the same time.

Refer to Figure 3C, which is a schematic diagram of the DSDA mode. In Figure 3C, two SIM cards are respectively USIM1 and USIM2 as an example. When USIM1 is working (or when it enters the RRC connected state), that is, when USIM1 is sending and receiving data, USIM2 can also work, that is, USIM2 and USIM1 can be in the RRC connected state at the same time.

The following introduces the above three radio resource control (radio resource control, RRC) states of the terminal device. As mentioned above, the three RRC states are: RRC connected state (connected state), RRC idle state (idle state) and inactive state (inactive state). Among them, the inactive state can also be referred to as an inactive state or a deactivated state.

RRC connected state (or, can also be referred to as connected state for short. In this article, "connected state" and "RRC connected state" are the same concept, and the two terms can be interchanged): the terminal device establishes an RRC connection with the network, and it can Perform data transfer.

RRC idle state (or, can also be referred to as idle state for short. In this article, "idle state" and "RRC idle state" are the same concept, and the two terms can be interchanged): the terminal device does not establish an RRC connection with the network, and the base station The context of the terminal device is not stored. If the terminal device needs to enter the RRC connected state from the idle state, it needs to initiate an RRC connection establishment process.

Inactive state: The terminal device entered the RRC connected state before, and then the base station releases the RRC connection, but the base station saves the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the inactive state, it needs to initiate the RRC connection recovery process (or called the RRC connection re-establishment process). Compared with the RRC establishment process, the RRC recovery process has shorter time delay and lower signaling overhead. However, the base station needs to save the context of the terminal device, which will occupy the storage overhead of the base station.

When the terminal device has no data transmission, in order to save power, the terminal device enters an idle state or an inactive state. In this state, the terminal device needs to wake up at a certain position in a certain period to monitor whether the network is paging the terminal device. The location where the terminal device wakes up is the paging occasion (PO). Refer to Figure 4, which is a schematic flowchart of a network device initiating paging to a terminal device.

S11. The downlink data of the terminal equipment arrives at the core network equipment.

S12. The core network device sends a paging message to the base station, and the base station receives the paging message from the core network device.

For a terminal device in an idle state, when downlink data arrives at the core network device (that is, the network wants to send data to the terminal device), the core network sends a paging message to multiple access network devices under the terminal device registration area to trigger multiple access network devices. Each base station sends a paging message on the air interface. Figure 4 only takes one of the access network devices as an example.

Wherein, the paging message may include a user equipment identification (UE ID). As an example, the UE ID may be an S-temporary mobile subscriber identity (S-TMSI) allocated by the core network device to the terminal device. Optionally, the paging message may also include a paging cycle (which may be recorded as T1) allocated by the core network to the terminal device. As an example, the paging cycle may be a discontinuous reception (DRX) cycle, but the embodiment of the present application is not limited to this.

S13. The access network device determines the paging opportunity of the terminal device.

For inactive terminal devices, there are no steps S11 and S12. When downlink data arrives at the access network device, the access network device can determine to initiate a paging to the terminal device and determine the paging timing.

In some implementations, a cell-level paging cycle (which can be denoted as T2) can be broadcast in the system message of the cell broadcast by the base station. In addition, for a terminal device in the inactive state, the access network device will allocate a paging cycle (which can be recorded as T3) to the terminal device.

As an example, the access network device may determine the paging occasion PO of the terminal device based on the UE ID, paging cycle, and paging configuration parameters of the cell. Among them, for the terminal device in the idle state, the paging cycle used to determine the PO is the period with the smaller value of T1 and T2 (can be marked as T), and for the terminal device in the inactive state, it is used to determine the PO paging cycle It is the period with the smallest value among T1, T2, and T3 (can be denoted as T).

For a specific example, the cell paging configuration parameters broadcast in the system information of the cell may be as follows:

Among them, defaultPagingCycle is T2. Based on nAndPagingFrameOffset, the paging frame (PF) offset (which can be recorded as PF_offset) can be obtained, and N, where N is used to identify the number of PFs in a paging cycle, and Ns indicates a paging frame. The number of POs in the call frame.

The following takes the NR system as an example to describe the process of determining the paging occasion PO of the terminal device.

First, the paging frame PF in which the PO of the terminal device is located can be determined. As an example, the PF where the PO is located can be determined by the following formula (1).

(SFN+PF_offset) mod T = (T div N)*(UE_ID mod N) (1)

Among them, SFN represents the system frame number (system frame number), which is used to represent the frame number of the frame where the PF is located, PF_offset represents the offset of the PF, T represents the paging cycle of the terminal device, the unit is a frame, and N represents a paging cycle The number of inner PFs, T div N means that there is one PF every (T div N) consecutive frames, and the UE_ID is S-TMSI mode 1024.

Among them, the values of PF_offset, T, and N can all come from the broadcast of the current cell or are related to the parameters broadcast by the current cell.

After determining the PF, the time domain position of the PO of the terminal device in the PF can be determined. In the embodiments of the present application, the time domain position of the PO may also be referred to as the position of the PO. Exemplarily, the process of determining the position of the PO in the PF can be divided into the following steps a and b.

Step a: Obtain the PO number i_s through the following formula (2):

i_s=floor(UE_ID/N)mod Ns (2)

Step b: Obtain the time domain position of the PO according to the number of the PO. After obtaining the number of the PO, the time domain position of the PO of the terminal device can be obtained according to the configuration of the search space of the paging of the current cell.

In the LTE system, the paging frame PF where the paging occasion PO of the terminal device is located can be determined according to the following formula (3):

SFN mod T=(T div N)*(UE_ID mod N) (3)

After determining the PF, the process of determining the position of the PO of the terminal device in the PF is similar to the NR system, and will not be repeated here.

Similarly, the terminal device can also determine the time domain position of the PO based on the UE ID, paging cycle, and cell paging configuration parameters applicable to all terminal devices in the current cell.

S14. The access network device sends a paging message through the air interface, and the terminal device receives the paging message from the access network device.

The access network device sends a paging message on the air interface. Among them, if the access network device is configured with a radio access network-based notification area (RNA), the access network device will send paging at the paging occasion of the terminal device in the cell indicated by the RNA. If there is a cell belonging to another access network device in the cell indicated by RNA, the access network device can send a paging message to other access network devices, and the other access network devices can use the air interface at the paging occasion of the terminal device. Send a paging message.

Wherein, the paging message may carry the user equipment paging identity (UE paging identity), so that the terminal device receiving the paging message can identify whether the paging message is sent to itself.

The terminal device can monitor the physical downlink control channel (PDCCH) on the determined PO to receive the paging message. After receiving the paging message and determining that the terminal device is paged, the terminal device will initiate a new RRC connection establishment process on the cell where it currently resides, or initiate an RRC connection recovery process to enter the RRC connection state.

It can be seen from the above description that the parameters used to determine the time domain position of the PO of the terminal device include the UE ID, the paging cycle, and the cell paging configuration parameters of the current cell. When two SIM cards are inserted into a terminal device, the two SIM cards may reside in different cells, and the terminal device can register in different networks with the two user identities corresponding to the two SIM cards. For example, the terminal device registers on the first network with the identity of the first user corresponding to the first SIM card, and the terminal device registers on the second network with the identity of the second user corresponding to the second SIM card. After the registration is completed, the first network will allocate the user equipment identification of the first user identity to the terminal device of the first user identity, and the second network will allocate the user equipment identification of the second user identity to the terminal device of the second user identity. The terminal device determines the time domain position of the PO of the first user identity in the paging cycle of the first user identity, and determines the time domain position of the PO of the second user equipment in the paging cycle of the second user identity.

For terminal devices that support the first user identity and the second user identity, the time domain position of the PO of the first user identity may overlap with the time domain position of the PO of the second user identity (including full overlap and partial overlap) Case. At this time, for the terminal device in DSDS mode, since the terminal device can only listen to the paging message of one user identity at the PO location, if both the PO locations of the user identity have paging messages sent at this time, it will cause the terminal The device cannot receive the paging message of another user identity, that is, a paging conflict will occur between the first user identity and the second user identity, resulting in paging loss of one of the user identities, which will cause problems such as missed calls.

Or, it may happen that although the time domain position of the PO of the first user identity does not overlap with the time domain position of the PO of the second user identity, the gap between the two is small. In this case, since the interval between the two POs is very small, after receiving the paging message of the user identity on the PO of one user identity, the terminal device is too late to adjust the radio frequency, which may result in the failure to receive the other user. The paging message on the PO of the identity, at this time, the first user identity and the second user identity will also have a paging conflict, resulting in page loss of one of the user identities, thereby causing a missed call problem.

In view of this, the technical solutions of the embodiments of the present application are provided. In the embodiment of the present application, the terminal device supports the first user identity, and includes the first PO and the second PO in a paging cycle of the first user identity, that is, in the prior art, a user identity is in a paging cycle. There is only one PO for the user identity in a cycle, but in this embodiment of the present application, the first user identity includes two POs for the first user identity in one paging cycle. Among them, the first user identity can be understood as the user identity that the terminal device has after the SIM card 1 is installed. The access network device may send a paging message of the first user identity of the terminal device on both the first PO and the second PO. As the first user, the terminal device can choose to monitor the paging message of the first user on the first PO or the second PO. Therefore, in the embodiment of the present application, the first PO and the second PO are set in a paging cycle of the first user identity of the terminal device, and the access network device sends a paging message on both the first PO and the second PO. , So that when the terminal device monitors the paging message as the first user, it can choose to monitor the paging message on the first PO or monitor the paging message on the second PO, thereby helping to avoid page loss, and further Helps to avoid missed call problems caused by paging loss.

In some optional embodiments, the terminal device also supports the second user identity, and includes the third PO in one paging cycle of the second user identity. Among them, the second user identity can be understood as the user identity that the terminal device has after the SIM card 2 is installed. When a paging conflict occurs between the identity of the first user and the identity of the second user, the terminal device monitors the paging message of the second user identity on the third PO as the second user identity, and the terminal device does not communicate with the third user identity as the first user. The PO conflicting with the PO monitors the paging message of the first user identity.

In some implementation manners, even if there are two POs in one paging cycle for the first user identity, the terminal device may only need to monitor one of the POs. In this way, although the first user identity of the terminal device includes two POs in one paging cycle, the terminal device always only needs to wake up and listen to the paging message in one PO of the paging cycle, that is, each user of the terminal device The identities only monitor the paging message once in their corresponding paging cycle, which helps the terminal device to save energy.

For example, when the time domain position of the first PO in the paging cycle of the first user identity overlaps with the time domain position of the third PO in the paging cycle of the second user identity or the interval is very small (that is, the first PO and the first PO Three PO conflicts), the terminal device monitors the paging message of the second user identity on the third PO as the second user, and the terminal device monitors the paging message of the first user identity on the second PO as the first user Message, and the terminal device does not monitor the paging message of the first user on the first PO as the first user. That is, when a conflict occurs, since the first user identity has two POs in a paging cycle, the paging of the second user identity can be monitored first, and the first user identity can be monitored on another PO that does not conflict with the first user identity. User identity paging, which can ensure that the paging messages of the two user identities will not be lost.

For another example, when the time domain position of the second PO in the paging cycle of the first user identity overlaps with the time domain position of the third PO in the paging cycle of the second user identity or the interval is very small (that is, the first PO and The third PO conflicts), the terminal device monitors the paging message of the second user identity on the third PO as the second user, and the terminal device monitors the paging message of the first user identity on the first PO as the first user. Paging message, and the terminal device does not monitor the paging message of the first user identity on the second PO as the first user identity.

Fig. 5 shows an example of a paging cycle of a terminal device provided in an embodiment of the present application. As an example, the terminal device may install the SIM card 1 and the SIM card 2, wherein the terminal device has the first user identity after the SIM card 1 is installed, and has the second user identity after the SIM card 2 is installed. As shown in Figure 5, the first user identity corresponding to SIM card 1 includes two POs (ie, the first PO and the second PO) in a paging cycle, where the first PO can be marked as "1" and the second PO It can be marked as "2", and the second user identity corresponding to SIM card 2 includes a PO (that is, the third PO) in a paging cycle, which is marked as "1". Wherein, the time domain position of the first PO in the paging cycle of the first user identity overlaps with the time domain position of the third PO in the paging cycle of the second user identity. At this time, the terminal device can monitor the paging message on the PO marked "2" as the first user (due to the overlap, the terminal device may not monitor the paging message on the PO marked "1" as the first user) to The second user identity monitors the paging message on the PO marked "1".

For another example, when there is no conflict between the identity of the first user and the identity of the second user, the terminal device monitors the paging message of the first user identity on any PO in the paging cycle as the first user identity, and the terminal device uses the first user identity to monitor the paging message of the first user identity. Second, the user identity monitors the paging message of the second user identity on the third PO in the paging cycle. For example, when the time domain position of the first PO in the paging cycle of the first user identity and the time domain position of the third PO in the paging cycle of the second user identity do not overlap, and the interval is large, and the first user The time domain position of the second PO in the paging cycle of the identity and the time domain position of the third PO in the paging cycle of the second user identity do not overlap, and when the interval is large, the terminal device is in the first user identity as the first user. One PO and the second PO appear on the earlier PO to monitor the paging message of the first user identity, or the terminal device monitors the paging message of the first user identity on the PO calculated according to the UE ID as the first user Message, the terminal device listens to the paging message of the second user on the third PO as the second user.

It should be noted that in a paging cycle of the first user identity, in addition to the first PO and the second PO, other POs, such as the fourth PO, may also be included, which is not limited in the embodiment of the present application. The embodiments of this application will mainly be described based on the inclusion of two POs in the paging cycle. When more than two POs are included in the paging cycle, the specific implementation can refer to the related description of including two POs in the paging cycle. Some simple adaptations are made, but they are also within the protection scope of the embodiments of this application.

It is understandable that, based on the communication standard, it is possible to determine which SIM card of the terminal device includes at least two POs in the paging cycle. For example, considering backward compatibility, it is easier to introduce this mechanism into the NR communication system. Therefore, the user identity corresponding to the SIM card residing in the NR cell can be preferentially selected to include at least two POs in the paging cycle. Or in some optional embodiments, it may be implemented by a terminal device, which is not limited in the embodiment of the present application.

In some possible implementation manners, one of the two POs in the paging cycle of the first user identity, for example, the first PO may be determined according to the first user equipment identity of the first user identity. As an example, the first user equipment identification may be a user equipment identification assigned by the network to the terminal device when the terminal device is registered in the network as the first user. Exemplarily, the first PO may be determined according to the process of determining the PO described above and the first user equipment identifier.

In some optional embodiments, the first user equipment identifier is the temporary mobile user identification code S-TMSI of the first user identity.

In a possible implementation manner, the other of the two POs, for example, the second PO may be determined based on the second user equipment identification of the first user identity, where the second user equipment identification is different from the above-mentioned first user equipment identification. A user equipment identification. As an example, the second user equipment identity may be a user equipment identity that is different from the first user equipment identity of the first user identity that is additionally allocated by the core network device to the terminal device (that is, the first user identity is allocated by the core network device to two User equipment identification). Exemplarily, the second PO may be determined according to the procedure for determining the PO described above and the second user equipment identifier.

In some optional embodiments, the second user equipment is identified as another temporary mobile user identification code S-TMSI of the first user identity.

In another possible implementation manner, the other PO of the two POs, such as the second PO, may be determined according to the first user equipment identifier and the first offset value. The first offset value may be used to indicate the offset of the third user equipment identifier corresponding to the second PO relative to the first user equipment identifier. In other words, the first user equipment identification may be offset by the first offset value to obtain the third user equipment identification, and then the second PO may be determined according to the third user equipment identification. In some specific examples, the first offset value may be "1", or "2", or others. Exemplarily, the second PO may be determined according to the procedure for determining the PO described above and the third user equipment identifier.

It should be noted that the third user equipment identity here is not the user equipment identity of the first user identity, but the user equipment identity obtained by offsetting the user equipment identity of the first user identity.

In another possible implementation manner, the other of the two POs, such as the second PO, may be determined according to the time domain position of the first PO and the second offset value, where the second offset value is used for Indicates the offset of the time domain position of the second PO relative to the time domain position of the first PO.

As an example, the second offset value may be at least one of a radio frame offset value, a subframe offset value, and a paging frame offset value. For example, when the second offset value is 1 radio frame, the second PO is in the next radio frame after the time domain position of the first PO, and the position of the second PO in the next radio frame is the same as that of the first PO. The position in the radio frame is the same. For another example, when the second offset value is 1 paging frame, the second PO is in the next paging frame after the time domain position of the first PO, and the position of the second PO in the next paging frame is the same as that of the second PO in the next paging frame. The position of the first PO in the paging frame is the same. For another example, when the second offset value is 1 subframe, the second PO is in the next subframe after the time domain position of the first PO, and the position of the second PO in the next subframe is the same as that of the first PO. The positions in the subframes are the same.

For another example, when the second offset value is 1 radio frame and 1 subframe, the second PO is in the next radio frame after the time domain position where the first PO is located, and the second PO is in the next radio frame The time domain position of the first PO is offset by 1 subframe from the time domain position of the first PO in the radio frame in which it is located.

It should also be noted that in this embodiment of the application, it should be avoided that the time domain positions of the two POs in the paging cycle of the first user identity conflict with the time domain positions of the PO in the paging cycle of the second user identity.

For example, in the case where the paging cycle of the first user identity is an integer multiple of the paging cycle of the second user identity, for example, the paging cycle of the first user identity is 64 radio frames, and the paging of the second user identity The cycle is 32 radio frames. At this time, even if two POs are included in the paging cycle of the first user identity, it may happen that the time domain position of the two POs is exactly the same as that of the second user identity in two consecutive paging cycles. The time domain position of the PO overlaps.

At this time, in a possible way, the terminal device can send auxiliary information to the core network device as a user identity (such as the first user identity), and the auxiliary information is used to indicate the identity of the first user of the terminal device for determining The parameter of the paging occasion, and/or the parameter of the second user identity of the terminal device for determining the paging occasion. After receiving the auxiliary information, the core network device may determine the above-mentioned second user equipment identifier, or the first offset value, or the second offset value according to the auxiliary information. Therefore, the core network device can ensure based on the auxiliary information that the second PO derived based on the second user equipment identifier, or the first offset value, or the second offset value no longer conflicts with the PO of the second user identity, thereby Avoid the problem of paging message loss for the first user identity and the second user identity.

As an example, when the terminal device sends auxiliary information to the core network device as the first user, the auxiliary information may be one or a combination of the following information:

The paging cycle of the first user identity;

The paging resource configuration of the cell where the first user equipment is located, such as one or more of PF_offset, T, and N;

The paging cycle of the second user identity;

The paging resource configuration of the cell where the second user equipment is located, such as one or more of PF_offset, T, and N;

The S-TMSI of the second user identity.

In another example, when the terminal device sends auxiliary information to the core network device as the second user, the auxiliary information may be one or a combination of the following information:

The paging cycle of the first user identity;

The paging cycle of the second user identity;

The S-TMSI of the first user's identity.

In some optional embodiments, the paging cycle of the second user identity may also include two POs, such as a third PO and a fourth PO. In this case, in order to avoid the time domain positions of the two POs in the paging cycle of the first user identity and the time domain positions of the two POs in the paging cycle of the second user identity both overlapping or having a small interval In the case that the first PO in the paging cycle of the first user identity is determined according to the user equipment identity #1 of the first user identity, the second PO may be determined according to the "user equipment identity #1 + first bias In the case where the third PO in the paging cycle of the second user identity is determined according to the user equipment identity #2 of the second user identity, the fourth PO may be determined according to the “user equipment identity #2- The first offset value" is determined. In this way, the first PO and the second PO of the first user identity can be staggered with the third PO and the fourth PO of the second user identity as much as possible, so as to avoid paging conflicts between the first user identity and the second user identity.

Exemplarily, the first PO, the second PO, the third PO, and the fourth PO may be determined according to the process of determining the PO described above.

It should be understood that, in this embodiment of the present application, the second user identity of the terminal device may include one, two, or more than two POs in one paging cycle. When the second user identity includes two or more POs in a paging cycle, the access network device can send paging messages on both of the two or more POs, and the terminal device can use the first 2. User identity, choose to monitor the paging message on one of the POs. Therefore, the embodiments of the present application can help reduce the probability of paging conflicts among multiple user identities of the terminal device.

It should also be understood that in the embodiment of the present application, the terminal device can also install more than two SIM cards, and the corresponding terminal device also supports more than two user identities. For example, the terminal device supports three user identities and four user identities. Or more user identities, and can be registered in more than two networks, and each user identity can be registered in one network.

It should be understood that, in the embodiments shown herein, the first, second, and various numerical numbers are only for easy distinction for description, and are not used to limit the scope of the embodiments of the present application. For example, distinguish different user identities, different POs, and different access network devices.

It should also be understood that in the embodiments shown herein, "pre-defined" can be implemented by pre-saving corresponding codes, tables, or other methods that can be used to indicate related information in devices (for example, including terminal devices and network devices). , This application does not limit its specific implementation.

Hereinafter, without loss of generality, first, a paging process of a terminal device is taken as an example to describe the embodiments of the present application in detail. It can be understood that any terminal device in the wireless communication system or the chip configured in the terminal device can be paging based on the same method, and any access network device in the wireless communication system or configured in the access network device All the chips in the wireless communication system can perform paging based on the same method, and any core network device in the wireless communication system or the chip configured in the core network device can perform paging based on the same method. This application does not limit this.

Refer to FIG. 6, which is a schematic flowchart of a paging method according to an embodiment of this application. The paging method shown in FIG. 6 includes steps 610 to 660. In the embodiment of the present application, the terminal device supports at least two user identities, such as a first user identity and a second user identity.

It should be noted that, in this embodiment of the application, the terminal device interacts with the core network device and the access network device as the first user identity, and the paging cycle of the first user identity includes at least two POs as an example to describe the application The paging technical solution of the embodiment. The core network device that interacts with the terminal device of the first user identity is a core network device in the network where the terminal device is registered as the first user. However, the embodiment of the present application is not limited to this. For example, the terminal device may also interact with the core network device and the access network device as the second user identity, and the paging cycle of the second user identity includes at least two POs. The core network device that interacts with the terminal device of the second user identity is a core network device in the network where the terminal device is registered with the second user identity. Specifically, the process of the terminal device interacting with the network device as the second user can refer to the related description of the process of the terminal device interacting with the network device as the first user. Some simple adaptations may be required, but it is also implemented in this application. Within the scope of protection of the case.

Optionally, in step 610, the terminal device sends the first indication information to the core network device as the first user. Correspondingly, the core network device receives and saves the first instruction information. The first indication information is used to indicate that the terminal device supports at least two user identities, or is used to indicate that the first user identity of the terminal device includes at least two POs in a paging cycle, or is used to request the first user identity of the terminal device. The user identity includes at least two POs in a paging cycle.

When the first indication information is used to indicate that the terminal device supports at least two user identities, after receiving the first indication information, the core network device learns that the terminal device supports at least two user identities. At this time, in order to avoid paging conflicts among multiple user identities of the terminal device, the core network device may determine that the first user identity of the terminal device includes at least two POs in a paging cycle. Because the core network device is the core network device in the network where the terminal device is registered as the first user, from the perspective of the network side, the terminal device can be understood as a user, so "the core network device can determine the terminal device's The first user identity includes at least two POs in a paging cycle", which can also be described as: "The core network device can determine that the terminal device includes at least two POs in a paging cycle". The content indicated by the two description methods is the same and can be replaced with each other.

In a possible situation, when the terminal device determines that the time domain position of the PO of its first user identity and the time domain position of the PO of the second user identity completely or partially overlap, or the interval is small (real-time domain position conflict), Send the first indication information to the core network device as the first user. At this time, the first indication information may also be used to indicate that at least two user identities of the terminal device have a paging conflict. In this case, if the terminal device is in the idle state, the terminal device needs to enter the RRC connected state to send the first indication information.

In another possible situation, when the terminal device supports at least two user identities, regardless of whether the two user identities may have a paging conflict, the terminal device sends the first indication information to indicate the core network device. The terminal device supports at least two user identities. For example, after the terminal device is turned on, if it is found that two SIM cards are installed in the terminal device, the terminal device can send a registration request message to the core network device under the first user identity corresponding to SIM card 1. The registration request message may Carry the first indication information, which is used to indicate that the terminal device supports at least two user identities.

Optionally, the terminal device sends a registration request message to the core network device in the second user identity corresponding to the SIM card 2, and the registration request message may not carry indication information for indicating that the terminal device supports at least two user identities. In other words, at this time, the paging cycle of the second user identity of the terminal device may include only one PO.

Therefore, by sending the first indication information as the first user identity to the core network device under the condition that the terminal device supports at least two user identities regardless of whether the paging of the at least two user identities conflicts, it is possible to realize that there is no need to frequently Notify the network device whether it is necessary to send paging messages on at least two POs, thereby reducing the signaling overhead of the system, and is easier to implement.

In other possible situations, the first indication information may be used to request the core network device to allocate an additional user equipment identifier for the first user identity of the terminal device. Wherein, the additional user equipment identifier is used to determine the second PO in the paging cycle of the first user identity.

As an example, when determining that at least two user identities of the terminal device will have a paging conflict, or the terminal device supports at least two user identities, the terminal device may send the first indication information to the core network device to request the core network device Assign an additional user equipment identity to the first user identity of the terminal device. Or, it can also be described as requesting the core network device to allocate an additional user equipment identifier to the terminal device. After the core network receives the first indication information, it can learn that the terminal device needs at least two POs in a paging cycle, that is, it can be inferred that the terminal device supports at least two user identities, or that the terminal device supports at least two user identities. Paging conflicts may occur for user identity. At this time, in order to avoid paging conflicts among multiple user identities of the terminal device, the core network device may assign an additional user equipment identifier to the terminal device. As an example, the additional user equipment identification may be the second user equipment identification shown above.

In some possible implementation manners, the terminal device may send the first indication information to the core network device through a non-access stratum (Non-access stratum, NAS) message. In other words, the NAS message may carry the first indication information. As an example, the NAS message may be a NAS registration request message. Exemplarily, the parameters constituting the NAS message may include at least one of terminal identification, terminal capability, registration type, protocol data unit (PDU) session identification, data network name DNN, or other parameters. The registration type may include the registration type of paging conflict. That is to say, the registration type of the paging conflict at this time may be an example of the first indication information.

In some possible implementation manners, the terminal device may send the first indication information to the access network device through an RRC message (such as an RRC establishment complete message). Then, the access network device may send the first indication information to the core network device through a communication interface (such as an N2 interface) between the access network device and the core network device. As an example, the access network device may send an initial UE message to the core network through the N2 interface, and the initial UE message carries the first indication information.

Optionally, in step 615, the core network device may also send the second user equipment identifier, or the first offset value, or the second offset value to the terminal device. Correspondingly, the terminal device may receive the second user equipment identifier, the first offset value, or the second offset value from the core network as the first user identity.

As an example, the core network device may send a NAS registration response message to the terminal device, which includes the second user equipment identifier, or the first offset value, or the second offset value.

Specifically, the second user equipment identifier, the first offset value, and the second offset value can be referred to the above description, and for brevity, the details are not repeated here.

620. The core network device sends second indication information to the access network device, where the second indication information is used to instruct the access network device to send a paging message to the terminal device on the at least two POs.

Exemplarily, the at least two POs include a first PO and a second PO. Specifically, the first PO and the second PO can refer to the above description.

In a possible situation, the second indication information may include the first user equipment identification and the second user equipment identification of the first user identity of the terminal device, where the first user equipment identification is used to determine the first PO, The second user equipment identifier is used to determine the second PO.

Exemplarily, the first user equipment identification can be brought into the above formula (1) to formula (3) to determine the first PO, and the second user equipment identification can be brought into the above formula (1) to formula ( 3) to determine the second PO, but the embodiment of the application is not limited to this.

Or, in another possible situation, the second indication information includes the first user equipment identifier of the first user identity of the terminal device and the first offset value, where the first user equipment identifier is used to determine the first PO, the first offset value is used to determine the second PO. As an example, the second PO may be determined based on the first user equipment identification and the first offset value.

Exemplarily, the third user equipment identifier (for example, the sum or difference between the first user equipment identifier and the first offset value) may be obtained according to the first user equipment identifier and the first offset value. Then, the third user equipment identifier is brought into the above formula (1) to formula (3) to determine the second PO, but the embodiment of the present application is not limited to this.

Or, in another possible situation, the second indication information includes the first user equipment identifier and the second offset value of the first user identity of the terminal equipment, where the first user equipment identifier is used to determine the first PO, The second offset value is used to determine the second PO, and the second offset value is used to indicate the offset of the time domain position of the second PO relative to the time domain position of the first PO.

In some possible implementation manners, the second indication information may be used to indicate that the terminal device supports at least two user identities, or used to indicate that the first user identity of the terminal device includes at least two POs in one paging cycle. In this way, the access network device can determine to send a paging message to the terminal device on at least two POs in the paging cycle of the first user identity according to the second indication information.

In this way, when the access network device receives the second indication information, it can determine, according to the content in the second indication information, that the terminal device sends a paging message on the above at least two POs. Further, the access network device may also determine the first PO and the second PO of the at least two POs according to the content in the second indication information.

It should be noted that the second indication information may be explicit indication information or implicit indication information. For example, if the core network device sends the second user equipment identifier, or the first offset value, or the second offset value to the access network device, it means that the core network device sends the second indication information to the access network device. According to this, the access network device can determine that the first user identity of the terminal device includes at least two POs in a paging cycle.

It should be noted that the access network device is not necessarily the access network device in step 610. For example, as the terminal device moves, the terminal device has been handed over from the cell of the access network device in step 610 to the cell of the access network device in step 620.

As an example, the core network device may send the second indication information to the access network device through a paging message or an initial context establishment request message. Specifically, it will be described in detail below.

630: The access network device determines the first PO and the second PO.

As an example, the access network device may determine the time domain location of the first PO and the second PO according to the second indication information.

In another example, the access network device may determine the first PO in the paging cycle of the first user according to the first user equipment identifier assigned by the core network device to the first user identity of the terminal device. Further, the access network device may determine the second PO according to a preset pre-defined (for example, pre-stored by the access network device), or a first offset value or a second offset value pre-defined by a protocol.

Specifically, the process of determining the first PO and the second PO can be referred to the above description, and for the sake of brevity, it will not be repeated here.

640. The terminal device determines the first PO and the second PO.

As an example, the terminal device may determine the first PO in the paging cycle of the first user according to the first user equipment identifier assigned by the core network device to the first user identity of the terminal device.

Further, the access network device may be pre-defined according to presets (such as pre-stored by the terminal device), or the first offset value or the second offset value may be pre-defined by the protocol, or received from the core network device as the first user The second user equipment identifier, or the first offset value, or the second offset value that comes, determines the second PO.

650. The terminal device monitors the paging message on the first PO or the second PO.

As an example, the terminal device monitors the paging message on which PO of the first PO or the second PO of the first user identity, depending on which PO is not in the time domain with the third PO in the paging cycle of the second user identity. Conflict in location. For details, please refer to the above description. For brevity, details are not repeated here.

660: The access network device sends a paging message on the first PO.

670. The access network device sends a paging message on the second PO.

Therefore, in the embodiment of the present application, when the terminal device supports the first user identity and the second user identity, by setting the first PO and the second PO in a paging cycle of the first user identity of the terminal device, When the terminal device monitors the paging message as the first user, it can select the PO in the paging cycle that does not have the second user identity to monitor on the PO that conflicts with the time domain resource, thereby avoiding multiple users of the terminal device The identity has the problem of paging message loss.

FIG. 7 shows a schematic flowchart of another paging method provided by an embodiment of the present application. In the method shown in FIG. 7, when the first user identity of the terminal device is in the idle state, the paging message is monitored on the first PO or the second PO.

It should be understood that FIG. 7 shows the steps or operations of the paging method, but these steps or operations are only examples, and the embodiment of the present application may also perform other operations or variations of each operation in FIG. 7. In addition, the various steps in Fig. 7 may be performed in a different order from that presented in Fig. 7, and it is possible that not all the operations in Fig. 7 are to be performed.

701: A terminal device sends first indication information to a core network device. Correspondingly, the core network device receives the first indication information.

Specifically, step 701 can be referred to the description of step 601 in FIG.

702. The core network device saves the foregoing first indication information.

Optionally, the core network device may additionally allocate a new user equipment identity to the terminal device according to the first indication information, that is, the first user identity of the terminal device has two user equipment identities. As an example, the user equipment identifier may be S-TMSI.

Optionally, 703, the core network device sends the second user equipment identifier, or the first offset value, or the second offset value to the terminal device.

In some possible implementation manners, the terminal device and the access network device may determine the second PO according to the first offset value and the second offset value. At this time, the core network device may not send the above-mentioned second user equipment identifier to the terminal device. Optionally, the first offset value or the second offset value may also be defined in advance, which is not limited in the embodiment of the present application.

Specifically, in step 703, and the second user equipment identifier, or the first offset value, or the second offset value, please refer to the relevant description above. For brevity, details are not repeated here.

It should be noted that, in this embodiment of the application, the terminal device sends the above-mentioned first indication information to the core network device in the RRC connected state. After sending the first indication information, the terminal device enters the idle state from the RRC connected state.

704: The core network device determines that the terminal device needs to be paged.

As an example, the core network may determine that the terminal device needs to be paged when the downlink data of the terminal device arrives.

It should be noted that for the terminal device in the idle state, the paging to the terminal device is triggered by the core network device. After the core network device determines that the terminal device needs to be paged, it sends a paging message to the access network device, that is, step 705 is executed.

705. The core network device sends a paging message to the access network device, where the paging message carries second indication information. Correspondingly, the access network device receives the second indication information. Since the paging message is sent through the NG interface between the core network device and the access network device, the paging message may also be called an NG paging message.

In some possible implementations, when the core network device additionally allocates the second user equipment identifier to the terminal device, the paging message may carry the first user equipment identifier and the second user equipment identifier of the first user identity of the terminal device. Logo. That is, the first user equipment identifier and the second user equipment identifier may be a specific example of the second indication information.

Specifically, for the second indication information, refer to the description of step 620 in FIG. 6, and for brevity, details are not described herein again.

706: The access network device determines the first PO and the second PO.

707. The terminal device determines the first PO and the second PO, and monitors the paging message on the first PO or the second PO.

708. The access network device sends a paging message on the first PO.

709: The access network device sends a paging message on the second PO.

In step 708 and step 709, since the paging message is transmitted on the air interface between the access network device and the terminal device, the paging message may also be referred to as an air interface paging message.

Specifically, steps 706 to 709 can refer to the descriptions of 630 to 670 in FIG.

FIG. 8 shows a schematic flowchart of another paging method provided by an embodiment of the present application. In the method shown in FIG. 8, when the first user identity of the terminal device is in the inactive state, the paging message is monitored on the first PO or the second PO.

It should be understood that FIG. 8 shows the steps or operations of the paging method, but these steps or operations are only examples, and the embodiment of the present application may also perform other operations or variations of each operation in FIG. 8. In addition, the various steps in FIG. 8 may be performed in a different order from that presented in FIG. 8, and it is possible that not all the operations in FIG. 8 are to be performed.

801: A terminal device sends first indication information to a core network device. Correspondingly, the core network device receives the first indication information.

Specifically, for step 801, refer to the description of step 601 in FIG. 6, and for brevity, details are not repeated here.

802. The core network device saves the foregoing first indication information.

Optionally, 803, the core network device sends the second user equipment identifier, or the first offset value, or the second offset value to the terminal device.

Specifically, step 803 can be referred to the description of 703 in FIG.

804. The core network device sends an initial context establishment request message to the first access network device, where the initial context establishment request message carries second indication information.

It should be noted that the first access network device in step 804 is the current serving access network device of the first user identity of the terminal device. In some possible embodiments, steps 801 to 803 and step 804 are relatively independent processes, that is, the first access network device and the terminal device in step 804 perform steps 801 to 803 corresponding to the first access The network access devices can be the same access network device or different access network devices.

For example, the first user identity of the terminal device enters the idle state after going through the above steps 801 to 803. Then, the terminal device will send data to the connected state with the first user device. At this time, the core network device sends an initial context establishment request message to the current serving access network device of the first user identity of the terminal device, and the initial context establishment request message carries the second indication information.

It can be seen that, for the terminal device in the inactive state, the core network device does not send the second indication information to the access network device through a paging message, but, for example, through the initial context establishment request message when the terminal device enters the connected state.

After sending the first indication information, the terminal device enters an inactive (inactive) state from the RRC connected state.

806: The first access network device determines that the terminal device needs to be paged.

As an example, the first access network device may determine that the terminal device needs to be paged when the downlink data of the terminal device arrives.

It should be noted that, for a terminal device in the inactive state, the first access network device needs to page the terminal device to enter the connected state. That is, for the terminal device in the inactive state, the air interface paging message is triggered by the access network device itself.

Optionally, 807, the first access network device sends a paging message to the second access network device, which carries second indication information. The paging message is used to instruct the second access network device to page the first user identity of the terminal device.

At this time, the first access network device is an access network device that saves the context of the first user identity of the terminal device, and may also be referred to as an anchor point access network device. Correspondingly, the second access network device may also be referred to as an adjacent access network device of the anchor point access network device. As an example, if the RAN notification area (RAN-based notification area, RNA) configured by the anchor access network device for the terminal device of the first user identity in the inactive state includes the adjacent access network device, the anchor access The network device sends a paging message to the neighboring access network device. The paging message contains second indication information for instructing the neighboring access network device to report to the terminal of the first user identity on at least two POs of the first user identity.

The PO or the second PO monitors the paging message of the second access network device, determines the first PO and the second PO with the first access network device, and the first access network device sends the paging message on the first PO or The process of sending a paging message on the second PO and that the terminal device monitors the paging message of the first access network device on the first PO or the second PO is similar.

According to the reassigned user equipment identification, a new PO can be determined in the paging cycle of the first user identity, the time domain position of the new PO and the time domain position of the PO in the paging cycle of the second user identity Does not overlap. At this time, the terminal device can monitor the paging message on the PO marked as new as the first user, and monitor the paging message on the PO marked as the paging cycle as the second user, thereby avoiding the identity of the first user and A paging conflict occurs in the identity of the second user.
