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

The first network side device can determine the target duration and send the target duration to the terminal when it discovers that the terminal context (UE CONTEXT) information needs to be released, for example, before releasing the UE CONTEXT or during the process of releasing the UE CONTEXT. The first network side device may be an AMF. The target duration is the running duration of the first timer.

Step 202: The first network side device runs a first timer according to the target duration, wherein the target network covers the terminal during the running of the first timer.

The first timer is a timer running on the first network side device. The first timer may be an existing timer on the first network side device, 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 first network side device communicates with the terminal based on the first timer. During the running of the first timer, the target network covers the terminal, and the first network side device can send information to the terminal, or receive information sent by the terminal. When the first timer runs, the target network does not cover the terminal, and the first network side device can not Send information to the terminal or not receive information from the terminal to save resources.

In this embodiment, the first network side device sends a target duration to the terminal; the first network side device runs a first timer according to the target duration, wherein the target network covers the terminal during the running of the first timer. ; The first network side device communicates with the terminal based on the first timer. In the above, the first network side device can communicate with the terminal during the running of the first timer to avoid waste of resources 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, before the first network side device sends the target duration to the terminal, the method further includes:

The first network side device determines the target network based on the coverage information of the target network Continue to cover the terminal for the first period of time;

The target duration is determined based on the first duration.

Specifically, the first network side device can determine the network coverage information based on ephemeris information or analysis using a 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.

When determining the target duration based on the first duration, the first duration can be used as the target duration, or the following method can be used: Determining the target duration based on the first duration includes:

The target duration is determined 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. 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. When the first network side device sends the target duration to the terminal, the target duration can be carried in a non-access stratum (None Access Stratem, NAS) message or a radio resource control (Radio Resource Control, RRC) message. For example, the first network side device sends a NAS message carrying the target duration to the terminal, or the first network side device sends a terminal context release command to the second network side device, and the terminal context release command carries the The second network side device then sends the RRC message carrying the target duration to the terminal. The second network side device may be a Radio Access Network (RAN).

In an embodiment of the present application, the coverage information is carried in a message received from the second network side device by the first network side device. For example, the coverage information is carried in a message sent by the second network side device to the first network side device. In the terminal context release request (UE CONTEXT RELEASE REQUEST) of the network side device.

In an embodiment of the present application, the first network side device may also actively query the second network side device for information to obtain coverage information of the target network. That is, before the first network side device sends the target duration to the terminal, the method further includes:

The first network side device sends query information to the second network side device, where the query information is used to query the coverage information of the target network;

The first network side device receives the coverage information sent by the second network side device.

The first network side device may determine the target duration according to the coverage information.

In an embodiment of the present application, the first network side device runs a first timer according to the target duration, including:

When the first timer is running, the first network side device stops the first timer, sets the value of the first timer to the target duration, and starts the first timer;

or,

When the first timer is not running, the first network side device sets the value of the first timer to a target duration and starts the first timer.

When the first timer is running, the first network side device sends a paging message, which can avoid resource waste.

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

Step 301: The terminal receives the target duration sent by the first network side device.

The target duration is determined by the first network side device. The first network side device can determine the target duration when it discovers that the terminal context (UE CONTEXT) information needs to be released, for example, before releasing the UE CONTEXT, or during the process of releasing the UE CONTEXT, And send the target duration to the terminal. The first network side device may be an AMF.

Step 302: The terminal runs a second timer according to the target duration, wherein the target network covers the terminal during the running of the second timer.

The second timer may be a timer running on the terminal. The second timer may be an existing timer on the terminal, or may be a newly added dedicated timer, which is not limited here. The second timer runs while the target network covers the terminal. The target network may be a satellite network.

Step 303: The terminal communicates with the first network side device based on the second timer.

During the running of the second timer, the target network covers the terminal, and the terminal can receive information sent by the first network side device. For example, the terminal can receive a paging message sent by the first network side device when it is in an idle state, or send a message to the third network side device. A network-side device sends information. When the first timer ends and the target network does not cover the terminal, the first network side device does not send the paging message to save resources.

In this embodiment, the terminal receives the target duration sent by the first network side device; the terminal runs a second timer according to the target duration, wherein the target network covers the terminal during the running of the second timer; The terminal communicates with the first network side device based on the second timer.

The target duration is carried in the NAS message or RRC message. For example, the first network side device sends a NAS message carrying the target duration to the terminal, or the first network side device sends a terminal context release command to the second network side device, and the terminal context release command carries the The target duration is determined by the second network side device, and the second network side device sends the RRC message carrying the target duration to the terminal. The second network side device may be the RAN.

In an embodiment of the present application, the terminal runs a second timer according to the target duration, including:

When the second timer is running, the terminal stops the second timer, sets the value of the second timer to the target duration, and starts the second timer;

or,

When the second timer is not running, the terminal sets the value of the second timer to the target duration and starts the second timer.

When the second timer is running, the terminal receives the paging message, that is, the terminal receives the paging message when the target network is covered, which can avoid resource waste.

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

Figure 4a shows a schematic diagram of the interaction between the terminal and the network side device. The AMF sends the target duration to the terminal before the satellite cell releases the connection. The following description takes the target duration as the duration set for T3324 as an example.

Step 401, RAN sends a terminal context release request (UE CONTEXT RELEASE REQUEST) message. Optionally, the request can carry the coverage information of the target network, such as the start time and stop time of the coverage.

Step 402: Before AMF releases the UE context, AMF has not obtained the coverage of the target network. In the case of coverage information, for example, if the terminal context release request does not carry coverage information, the AMF can send query information to the RAN to request coverage information of the target network.

Step 402': After receiving the query information, the RAN returns coverage information to the AMF.

Step 403, before AMF releases the UE context, AMF calculates the coverage loss time T1 (that is, the continued coverage time) based on the coverage information, and compares the value of T1 with T3324. The value of T3324 is the value sent by AMF to the terminal in the registration success message. Select The smaller of the two is used as the target duration.

Step 404, AMF sends a NAS message to the terminal, carrying the value of T3324; the NAS message can be NAS TRANSPORT, configuration update command (CONFIGURATION UPDATE COMMAND), etc.;

Or, in step 405, the AMF sends a context release command (UE CONTEXT RELEASE COMMAND) to the RAN, carrying the value of T3324; for example, carrying the value of T3324 in a container (container), carrying the container in the RRC message, and sending it to the UE; RRC The message can be RRCReconfiguration message, RRCRelease message, etc.;

Step 406: RAN releases the RRC connection and carries the value of T3324 in the RRC release connection message.

During the operation of T3324, the UE can receive paging messages (PAGING), the first timer (ie, activation timer) times out, and the AMF no longer sends paging messages.

Figure 4b shows a schematic diagram of the interaction between the terminal and the network side device. In this embodiment, the terminal and the network side device each add a new timer. The new timer is based on the length of time the target network continues to cover the terminal, and monitors other power-saving function related timers, such as the operation of T3324.

AMF determines T1, which is the remaining coverage duration (also called continued coverage duration); AMF sends T1 to the UE through a NAS message;

AMF sets the first timer with the value of T1, including: if the first timer is running, stopping the first timer, setting the first timer with the value of T1, and restarting the first timer; if the first timer is running, If the timer is not running, set the first timer with the value of T1 and start the first timer.

When the first timer times out, AMF considers that the UE coverage is lost, stops the activation timer (active time), no longer sends paging messages, and considers that the UE is unreachable, stops the reachable timer, and stops implicit de-registration ( implicit de-registration) timer;

When the UE receives T1, the UE sets the second timer with the value of T1, including: if the second timer is If the second timer is running, stop the second timer, set the second timer with the value of T1, and restart the second timer; if the second timer is not running, set the second timer with the value of T1, and start the second timer. device.

After starting, the second timer continues to run regardless of the UE connection state or IDLE state; since T1 is the predicted remaining coverage duration, the second timer does not time out during the coverage period;

The second timer times out, indicating coverage loss, triggering the UE to stop T3324, active time, stop receiving paging, stop periodic registration timer, and stop high-priority network search timer;

The newly added timer on the AMF side is the first timer, and the new timer on the UE is the second timer. Both the first timer and the second timer are timers used to determine the coverage duration of the target network coverage terminal. During the running of the first timer and the second timer, the target network covers the terminal. The existing timer on the terminal can run with the second timer as a reference. For example, T3324 can run during the running of the second timer and stop running when the second timer times out.

In the communication method in this application, the terminal uses a second timer to record how long the target network continues to cover the terminal, and the network side device uses a first timer to record how long the target network continues to cover the terminal. When the first timer or the second timer times out, , it is considered that the terminal has lost the coverage of the target network, and the network side device can no longer try to initiate the NAS signaling process to avoid failed NAS processes and reduce resource waste.
