The methods provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

As shown in Figure 2, this embodiment of the present application provides a communication method, which includes the following steps:

Step 201: The terminal obtains the target duration.

There are two ways for the terminal to obtain the target duration in this application. One is that the terminal calculates and obtains the target duration. For example, the terminal calculates and obtains the target duration based on the network coverage information (also called coverage information) of the target network. , the other is to obtain the target duration from the first network side device, that is, the terminal receives the target duration sent by the first network side device.

The terminal can calculate the target duration when entering the idle state (5G Mobility Management (5GMM)-IDLE mode).

The first network side device may be an AMF. The target duration is the running duration of the first timer.

Step 202: The terminal runs a first timer according to the target duration, wherein the target The network covers the terminal.

The first timer is the timer that runs on the terminal. The first timer may be an existing timer on the terminal, or may be a newly added dedicated timer, which is not limited here. The first timer runs during the target network coverage of the terminal. The target network may be a satellite network.

Step 203: The terminal communicates with the first network side device based on the first timer. During the running of the first timer, the target network covers the terminal, and the terminal can receive information sent by the first network side device, such as paging messages; when the first timer runs, the target network no longer covers the terminal, and the terminal does not receive information from the first network side device. The information sent by the device can save resources.

In this embodiment, the terminal obtains the target duration; the terminal runs a first timer according to the target duration, wherein the target network covers the terminal during the running of the first timer; the terminal communicates with the first network side based on the first timer. devices communicate. In the above, the terminal can communicate with the first network side device during the running of the first timer, which can avoid resource waste caused by the terminal being unable to receive information sent by the first network side device when the target network does not cover the terminal.

In an embodiment of the present application, the terminal calculates and obtains the target duration based on the network coverage information of the target network, including:

The terminal obtains a first duration for which the target network continues to cover the terminal according to the network coverage information of the target network;

The terminal calculates and obtains the target duration based on the first duration and a preset duration, where the preset duration is a value preset by the first network side device for a timer or time window of the terminal.

The terminal can determine the coverage information of the target network based on ephemeris information or analysis using Network Data Analytics Function (NWDAF). The first period of time that the target network continues to cover the terminal can be understood as the period of time that the target network currently covers the terminal and will continue to cover the terminal in the future.

The first duration may be used as the target duration, or the target duration may be determined based on the first duration and a preset duration. The preset duration is a timer set by the first network side device for the terminal in advance. Or the value of the time window setting. For example, the preset duration may be a duration set by the first network side device for the terminal when the terminal sends a registration request to the first network side device. The preset duration is one of the following:

(1) The running time of the activation timer of the terminal, the activation timer can be T3324;

(2) The running time of the periodic registration timer of the terminal, the periodic registration timer can be T3412;

(3) The length of the time window for the first network side device to page the terminal;

(4) The cycle length of the first network side device paging the terminal.

The target duration is the smaller of the first duration and the preset duration.

In an embodiment of the present application, the terminal communicates with the first network side device based on the first timer, including:

When the first timer is running, the terminal receives the paging message sent by the first network side device.

The terminal may also obtain the target duration from the first network side device. Before that, the terminal sends a registration request to the second network side device. That is, before the terminal receives the target duration sent by the first network side device, the terminal Method also includes include:

The terminal sends a registration request to the second network side device under preset conditions, so that the second network side device sends a first message for initializing the terminal to the first network side device, and the first network side device The side device determines the target duration according to the first message, and sends a registration success message to the terminal, where the registration success message carries the target duration. The second network side device may be a radio access network (Radio Access Network, RAN) to which the terminal accesses.

The preset conditions include one of the following:

The network coverage information of the cell where the terminal is located changes, and the target network is the network of the cell after the change;

The terminal moves from the first cell to the second cell, the target network is the network of the second cell, and the network coverage information of the first cell is different from the network coverage information of the second cell.

Specifically, if the network coverage information of the cell where the terminal is located changes, for example, from the first network to the target network, the terminal sends a first message to the second network side device to update the first timer or time window; Or, if the terminal moves from the first cell to the second cell and the network coverage information of the first cell and the second cell is different, for example, the terminal changes from the second network to the target network, the terminal sends the first message to the second network side device. , to update the time of the first timer or time window.

As shown in Figure 3, this embodiment of the present application provides a communication method, which includes the following steps:

Step 301: The terminal obtains the target duration.

There are two ways for the terminal to obtain the target duration in this application. One is for the terminal to calculate and obtain the target duration. For example, the terminal calculates and obtains the target duration based on the network coverage information of the target network. The other is to obtain the target duration from the first The network side device obtains the target duration, that is, the terminal receives the target duration sent by the first network side device.

The terminal can calculate the target duration when entering the idle state (5GMM-IDLE mode).

Step 302: The terminal runs a first timer according to the target duration, wherein during the running of the first timer, the target network covers the terminal in the starting time period of the target duration, and the target network covers the terminal in the starting time period of the target duration. The end time of the duration starts to cover the terminal or the end time period covers the terminal.

The first timer is the timer that runs on the terminal. The first timer may be an existing timer on the terminal, or may be a newly added dedicated timer, which is not limited here. During the running of the first timer, the target network covers the terminal intermittently. For example, during the running of the first timer, the target network covers the terminal at the beginning of the target duration, and the target network starts to cover the terminal at the end of the target duration or The end period covers the terminal. That is to say, during the running of the first timer, the target network moves from the covered terminal to the non-covered terminal, and after the target time period, the target network will cover the terminal again; or, during the running of the first timer, the target network moves from the covered terminal to the uncovered terminal. Uncovered terminal, then covered terminal. The time period between the start time period and the end time period is the time period when the target network does not cover the terminal. The starting time point of the starting time period is the starting time point of the target duration, and the ending time point of the ending time period is the ending time point of the target duration. The ending time point can also be called the ending moment.

The target network may be a satellite network.

Step 303: The terminal communicates with the first network side device based on the first timer. The terminal can be The first timer determines to communicate with the first network side device within a time period when the target network covers the terminal, for example, receives a paging message sent by the first network side device within the starting time period. During the running of the first timer, the target network does not cover the terminal at times other than the starting time period, and the terminal cannot receive the paging message sent by the first network side device. The terminal may not receive paging messages during this time period. processing to avoid wasting resources.

In this embodiment, the terminal obtains the target duration; the terminal runs a first timer according to the target duration, wherein during the running of the first timer, the target network covers the terminal in the starting time period of the target duration, and the target The network starts covering the terminal at the end of the target duration or covers the terminal at the end of the time period; the terminal communicates with the first network side device based on the first timer. In the above, the terminal can communicate with the first network side device during the time period when the target network covers the terminal during the running of the first timer, which can avoid the terminal being unable to receive the message sent by the first network side device when the target network does not cover the terminal. Waste of resources caused by information.

The terminal obtains a first duration based on the network coverage information of the target network, and the first duration is determined based on the duration from the target network continuing to cover the terminal to not covering the terminal to covering the terminal again. ;

The terminal calculates and obtains the target duration based on the first duration and a preset duration, where the preset duration is a value of a timer set by the first network side device for the terminal in advance. The target duration is the smaller of the first duration and the preset duration. The preset duration is the setting value of the periodic registration timer.

In the above, the first duration satisfies the following relationship:

T1+T2≤T≤T1+T2+T3;

Wherein, T is the first duration, T1 is the duration that the target network continues to cover the terminal, T2 is the duration that the target network does not cover the terminal, and T3 is the duration that the target network covers the terminal again.

During the operation of the second timer, the target network starts to cover the terminal at the end of the target duration or covers the terminal at the end of the time period; the first network side device is based on the second timing. The server communicates with the terminal. In the above, the network side device can communicate with the terminal during the running of the second timer, which can avoid resource waste caused by the first network side device still sending information when the target network does not cover the terminal.

The first network side device obtains a first duration according to the network coverage information of the target network. The first duration is based on the target network from continuing to cover the terminal to not covering the terminal to covering the terminal again. The duration of the terminal is determined;

The first network side device calculates and obtains the target duration based on the first duration and a preset duration. The preset duration is a value that the first network side device presets for the timer of the terminal. The target duration is the smaller of the first duration and the preset duration. The preset duration is the setting value of the periodic registration timer.

In the above, the first duration satisfies the following relationship:

T1+T2≤T≤T1+T2+T3;

In an implementation of the present application, the first network side device communicates with the terminal based on the second timer, including:

When the second timer is running, the first network side device sends a paging message within a time period when the target network covers the terminal.

The first network side device may also send the obtained target duration to the terminal. In one implementation of the present application, the first network side device determines the target duration, including:

The first network side device sends the target duration to the terminal.

In the paging strategy in the terrestrial network, the first paging is performed on the last tracking area TA. The satellite network currently uses the same paging measurement as the terrestrial network. However, in the terrestrial network, network coverage is usually fixed. , and satellite network coverage may vary with satellites. The network side device currently does not consider whether the TA has coverage when paging. When paging in a satellite network, a certain Public Land Mobile Network (PLMN) broadcast by the RAN may correspond to multiple tracking areas (Tracking Area, TA). When satellite is connected, it is currently unclear how to determine the last known TA, and the coverage of TA is not considered, resulting in the inability to paging efficiently in a multi-TAI scenario. In order to solve the above problems, this application provides a communication method, as shown in Figure 6, including the following steps:

Step 601: The first network side device obtains the location information of the terminal.

The first network side device may obtain the location information of the terminal through a location reporting process or a location services (Location Services, LCS) process. The location information may include a Tracking Area Identity (TAI) of the terminal's geographical location, or may not include a Tracking Area Identity (TAI) of the terminal's geographical location.

The first network side device may obtain the location information of the terminal before releasing the terminal context (UE CONTEXT) information.

Step 602: The first network side device determines the first target TA based on the location information. For example, when the location information includes a tracking area identifier TAI of the terminal's geographical location, the first network side device determines that the tracking area identified by the TAI is the first target TA. In the case where the location information does not include the TAI of the terminal's geographical location, the first network side device obtains at least one tracking area code TAC, and determines the first target TA based on the at least one TAC.

Step 603: The first network side device performs paging when the first target TA is covered by the network.

The first network side device may determine whether the first target TA is covered by the network based on network coverage information, such as ephemeris information, and perform paging if the first target TA is covered by the network. The network may be a satellite network. Place The paging includes first paging or non-first paging.

In this embodiment, the first network side device obtains the location information of the terminal; the first network side device determines the first target tracking area TA based on the location information; the first network side device determines the first target tracking area TA when the first target TA is covered by the network. perform paging. Through the above method, the first network side device can determine the first target TA by obtaining the location information of the terminal, and perform paging when the first target TA is covered by the network, which can effectively ensure that the terminal can receive the paging message. Improve paging success rate.

In an embodiment of the present application, if the location information includes the TAI of the geographical location of the terminal, the first network side device performs searching when the first target TA is covered by the network. After calling, the method also includes:

In the case where the first network side device fails to paging on the first target TA, the first network side device determines a second target TA based on the at least one TAC;

When the second target TA is covered by the network, the first network side device performs paging on the second target TA.

In the above, if the first network side device fails to paging on the first target TA, the first network side device determines the second target TA, and then executes on the second target TA when the second target TA is covered by the network. paging. The at least one TAC includes:

At least one tracking area code TAC in the registered public land mobile network RPLMN indicated by the terminal's serving cell; or at least one TAC of the public land mobile network PLMN equivalent to the RPLMN; wherein, the at least one TAC In the registration area RA of the terminal.

In the above, the TA covered by the network in the at least one TAC is determined as the second target TA, and the second network side device performs paging on the second target TA.

In an embodiment of the present application, the first network side device determines the first target tracking area TA based on the location information, including:

In the case where the location information does not include the TAI of the terminal's geographical location, the first network side device obtains at least one tracking area code TAC;

The first network side device determines the first target TA based on the at least one TAC, for example, determines a TA covered by the network in the at least one TAC as the first target TA. The at least one TAC includes:

At least one tracking area code TAC in the registered public land mobile network (Registered Public Land Mobile Network, RPLMN) indicated by the serving cell of the terminal; or at least one TAC of the public land mobile network PLMN equivalent to the RPLMN ; Wherein, the at least one TAC is in the registration area RA of the terminal.

The following is an example of the communication method provided by this application.

Figure 7a shows the terminal and the network side device each locally calculating the target duration. As shown in Figure 7a, the terminal can calculate the target duration when the terminal enters the idle state, and the AMF can receive the terminal context release completion message (UE CONTEXT RELEASE COMPLETE), the target duration is set for T3324 duration.

Figure 7b shows a schematic diagram of the interaction between the terminal and the network side device. In this embodiment, the coverage information of the cell where the terminal is located changes, the terminal moves from the first cell to the second cell, the coverage information of the two cells is different, and the second cell is a cell covered by the target network. After determining that the coverage information of the first cell and the second cell is different, the terminal triggers a registration request and sends a registration request to RAN2. RAN2 sends initialization terminal information to AMF. If the initialization terminal information carries the coverage information of the target network, AMF will The coverage information determines the target duration; if the initialized terminal information does not carry the coverage information of the target network, AMF sends query information to RAN2. The query information is used to query the coverage information of the target network, and RAN2 feeds back the coverage information to AMF. After obtaining the target duration, AMF sends a registration success message to the terminal, and carries the target duration in the registration success message. The target duration is the value of T3324.

Figure 7c shows a schematic diagram of the interaction between the terminal and the network side device. In this embodiment, the coverage information of the cell where the terminal is located changes. The cell where the terminal is located does not change, but the network information of the network covering the cell changes. The changed network is the target network. After determining that the coverage information of the cells is different, the terminal triggers a registration request and sends a registration request to RAN1. RAN1 sends initialization terminal information to AMF. If the initialization terminal information carries the coverage information of the target network, AMF determines the target duration based on the coverage information; If the initialized terminal information does not carry the coverage information of the target network, the AMF sends query information to RAN2. The query information is used to query the coverage information of the target network, and RAN2 feeds back the coverage information to the AMF. After obtaining the target duration, AMF sends a registration success message to the terminal, and carries the target duration in the registration success message. The target duration is the value of T3324.

Figure 7d shows a schematic diagram of the interaction between the terminal and the network side device. AMF obtains the TA-location report corresponding to the UE's actual geographical location before releasing the UE CONTEXT.

Before sending the terminal context release command message to RAN1, the AMF will initiate the location reporting process to request the last known location of the terminal. In the case of satellite access, RAN1 provides the TAI of all broadcasts of the selected PLMN to the AMF as part of the User Location Information (ULI). If RAN1 can determine the TAI of the geographical location of the UE, RAN1 also informs the AMF through the location report.

After AMF obtains the TAI of the terminal's geographical location, it sends a terminal context release command message (N2UE Context Release Command) to RAN1. RAN1 triggers the connection release and sends a terminal context release completion (N2UE Context Release Complete) message to AMF.

If the AMF knows the TAI of the terminal's geographical location, then this TAI is used as the last known TAI. The AMF determines that the TAI is within the coverage area during paging based on the ephemeris information, and then paging (PAGING) is performed first among the TAs identified by the TAI;

If AMF does not know the TAI of the terminal's geographical location, the TAI that meets the following conditions will be used as the latest known TAI:

One or more TACs of the RPLMN indicated by the UE's serving cell, or one or more TACs of the PLMN equivalent to the RPLMN, and these one or more TACs are in the UE's Registration Area (RA). The AMF determines based on the ephemeris information that these TACs are in the coverage area of the network during paging, and then paging is performed first among the TAs included in these TACs.

Figure 7e shows a schematic diagram of the interaction between the terminal and the network side device. Before AMF sends the terminal context release command message to RAN1, AMF starts the LCS process to request the location of the terminal. Through this LCS process, AMF gained The TA knows the geographical location of the UE. Other processes can be seen in Figure 7d and will not be described in detail here.
