The method provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 2, an embodiment of the present application provides a communication method, including the following steps:

step 201, the terminal obtains a target duration.

The terminal in the application obtains the target time length in two ways, one is that the terminal calculates and obtains the target time length, for example, the terminal calculates and obtains the target time length according to the network coverage information (also called as coverage information) of the target network, and the other is that the terminal obtains the target time length from the first network side equipment, namely, the terminal receives the target time length sent by the first network side equipment.

The terminal may calculate the target duration upon entering the IDLE state (5 GMM-IDLE mode).

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

Step 202, the terminal operates a first timer according to the target duration, wherein the target network covers the terminal during the operation of the first timer.

The first timer is a timer running on the terminal. The first timer may be an existing timer on the terminal or a newly added dedicated timer, which is not limited herein. The target network covers the terminal during the operation of the first timer. The target network may be a satellite network.

And 203, the terminal communicates with the first network side equipment based on the first timer. During the operation of the first timer, the target network covers the terminal, and the terminal can receive information, such as paging messages, sent by the first network side device; and when the first timer is finished, the target network does not cover the terminal any more, and the terminal does not receive the information sent by the first network side equipment, so that resources can be saved.

In this embodiment, the terminal acquires a target duration; the terminal runs a first timer according to the target duration, wherein a target network covers the terminal during the running of the first timer; and the terminal communicates with the first network side equipment based on the first timer. In the above, the terminal may communicate with the first network side device during the operation period of the first timer, so that resource waste caused by the fact that the terminal cannot receive the information sent by the first network side device when the target network does not cover the terminal can be avoided.

In one embodiment of the present application, the calculating, by the terminal, the target duration according to the network coverage information of the target network includes:

the terminal obtains a first duration of the target network continuing to cover the terminal according to the network coverage information of the target network;

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

The terminal may determine coverage information of the target network based on ephemeris information or analysis using a network data analysis function (Network Data Analytics Function, NWDAF). The first duration of the target network to continue to cover the terminal can be understood as the duration of the target network to continue to cover the terminal in the future.

The first time length may be used as a target time length, or the target time length may be determined according to the first time length and a preset time length, where the preset time length is a value preset by the first network side device for a timer or a time window of the terminal in advance. 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 time length is one of the following:

(1) The operation duration of the activation timer of the terminal can be T3324;

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

(3) The first network side equipment pages the time window length of the terminal;

(4) The first network side equipment pages the cycle length of the terminal.

The target time length is the smaller of the first time length and the preset time length.

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

and under the condition that the first timer runs, the terminal receives the paging message sent by the first network side equipment.

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 method further includes:

the terminal sends a registration request to second network side equipment under a preset condition, so that the second network side equipment sends a first message for initializing the terminal to the first network side equipment, the first network side equipment determines a target duration according to the first message and sends a registration success message to the terminal, and 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 has access.

The preset condition comprises one of the following:

the network coverage information of the cell in which the terminal is located is changed, and the target network is the network of the changed cell;

the terminal moves from a first cell to a second cell, the target network is a 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 in which the terminal is located changes, for example, the network coverage information is changed from the first network to the target network, the terminal sends a first message to the second network side device to update the time of the first timer or the 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 a first message to the second network side device so as to update the time of the first timer or the time window.

As shown in fig. 3, an embodiment of the present application provides a communication method, including the following steps:

step 301, the terminal acquires a target duration.

The terminal in the application obtains the target time length in two ways, one is that the terminal calculates and obtains the target time length, for example, the terminal calculates and obtains the target time length according to the network coverage information of the target network, and the other is that the terminal obtains the target time length from the first network side equipment, namely, the terminal receives the target time length sent by the first network side equipment.

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

The first timer is a timer running on the terminal. The first timer may be an existing timer on the terminal or a newly added dedicated timer, which is not limited herein. The target network intermittently covers the terminal during the operation of the first timer, for example, the target network covers the terminal during the operation of the first timer in the starting time period of the target duration, and the target network starts to cover the terminal at the ending time of the target duration or covers the terminal in the ending time period. That is, during the first timer run, the target network goes from covered to uncovered terminals, and after a target period of time the target network will again cover the terminals; alternatively, during operation of the first timer, the target network goes from the covered terminal to the uncovered terminal, and then to the covered terminal. The time period between the start time period and the end time period is a time period in which 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, the ending time point of the ending time period is the ending time point of the target duration, and the ending time point can be called as the ending time.

The target network may be a satellite network.

And step 303, the terminal communicates with the first network side equipment based on the first timer. The terminal may determine, according to the first timer, to communicate with the first network-side device during a period of time in which the target network covers the terminal, e.g., receive a paging message sent by the first network-side device during a start period of time. During the operation of the first timer, the time target network except the initial time period does not cover the terminal, the terminal cannot receive the paging message sent by the first network side device, and the terminal can not receive the paging message in the time period, so that resource waste is avoided.

In this embodiment, the terminal acquires a target duration; the method comprises the steps that a terminal runs a first timer according to a target duration, wherein a target network covers the terminal in a starting time period of the target duration during the running of the first timer, and the target network starts to cover the terminal at an ending time of the target duration or covers the terminal in an ending time period; and the terminal communicates with the first network side equipment based on the first timer. In the above, the terminal may communicate with the first network side device during a period when the target network covers the terminal during the operation of the first timer, so as to avoid resource waste caused by the fact that the terminal cannot receive the information sent by the first network side device when the target network does not cover the terminal.

the terminal obtains a first time length according to network coverage information of the target network, and the first time length is determined according to the time length from the continuous coverage of the terminal to the non-coverage of the terminal to the re-coverage of the terminal by the target network;

the terminal calculates and obtains the target duration according to the first duration and a preset duration, wherein the preset duration is a value of a timer of the terminal, which is preset by the first network side device. The target time length is the smaller of the first time length and the preset time length. The preset time length is a set value of a periodic registration timer.

In the above, the first time length satisfies the following relationship:

T1+T2≤T≤T1+T2+T3；

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

And under the condition that the first timer runs, the terminal receives the paging message sent by the first network side device in the time period of covering the terminal by the target network.

In one embodiment of the present application, before the terminal receives the target duration sent by the first network side device, the method further includes:

The preset condition comprises one of the following:

And the first network side equipment calculates and obtains the target duration according to the network coverage information of the target network. The first network side device may determine network coverage information of the target network based on the ephemeris information or an analysis using a network data analysis function (Network Data Analytics Function, NWDAF).

And step 402, the first network side equipment operates a second timer according to the target duration, wherein the target network covers the terminal during the operation of the second timer.

The first duration of the target network to continue to cover the terminal can be understood as the duration of the target network to continue to cover the terminal in the future. The second timer is a timer running on the first network side device.

And step 403, the first network side device communicates with the terminal based on the second timer. During the operation of the second timer, the target network covers the terminal, and the terminal can receive information, such as paging messages, sent by the first network side device; and when the second timer is finished, the target network does not cover the terminal any more, and the first network side equipment does not send information to the terminal, so that resources can be saved.

In this embodiment, the first network side device determines a target duration; the first network side device operates a second timer according to the target duration, wherein the target network covers the terminal during the operation of the second timer; the first network side equipment communicates with the terminal based on the second timer. In the above, the network side device can communicate with the terminal during the operation period of the second timer, so that resource waste caused by the fact that the first network side device still transmits information under the condition that the target network does not cover the terminal can be avoided.

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 time length is one of the following:

and the first network side equipment sends the target duration to the terminal.

In the above, the terminal sends a registration request to the second network side device under a preset condition, so that the second network side device sends a first message (i.e. INITIAL UE MESSAGE) for initializing the terminal to the first network side device, and the first network side device determines a target duration according to the first message and sends the target duration to the terminal.

The preset condition comprises one of the following:

The first message received by the first network side device may carry network coverage information, such as ephemeris information, of the target network, and the first network side device determines the target duration according to the network coverage information.

The second timer is a timer running on the first network side device. The second timer may be an existing timer on the terminal or a newly added dedicated timer, which is not limited herein. The target network intermittently covers the terminal during the second timer running, for example, the target network covers the terminal during the starting time period of the target duration, and the target network starts to cover the terminal at the ending time of the target duration or covers the terminal during the ending time period. That is, during the second timer run, the target network goes from covered to uncovered terminals, and after a target period of time the target network will again cover the terminals; alternatively, during operation of the second timer, the target network goes from the covered terminal to the uncovered terminal, and then to the covered terminal.

The first network side equipment obtains a first time length according to the network coverage information of the target network, and the first time length is determined according to the time length from the continuous coverage of the terminal to the non-coverage of the terminal to the re-coverage of the terminal of the target network;

the first network side device calculates and obtains the target duration according to the first duration and a preset duration, wherein the preset duration is a value preset by the first network side device for a timer of the terminal. The target time length is the smaller of the first time length and the preset time length. The preset time length is a set value of a periodic registration timer.

In the above, the first time length satisfies the following relationship:

and under the condition that the second timer runs, the first network side equipment sends a paging message in a time period of covering the terminal by the target network.

and the first network side equipment sends the target duration to the terminal.

The preset condition comprises one of the following:

In the paging strategy in a terrestrial network, a first paging is performed on the last tracking area TA, and the satellite network currently uses the same paging measurements as the terrestrial network, but since in a terrestrial network the network coverage is usually fixed, the coverage of the satellite network may change with satellite variations. The network side equipment does not consider whether the TA has coverage at present during paging. At paging in a satellite network, a public land mobile network (Public Land Mobile Network, PLMN) broadcast by the RAN may correspond to multiple Tracking Areas (TAs). At the time of satellite access, how to determine the last TA (last known TA) is not clear at present, and coverage of the TA is not considered, so that efficient paging in a multi-TAI scenario is not possible. In order to solve the above problems, the present application provides a communication method, as shown in fig. 6, comprising the steps of:

In step 601, the first network side device acquires location information of a terminal.

The first network side device may acquire location information of the terminal through a location reporting procedure or a location services (Location Services, LCS) procedure. The location information may or may not include a tracking area identity (Tracking Area Identity, TAI) of the geographic location of the terminal.

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

Step 602, the first network side device determines a first target TA according to the location information. For example, in the case that the location information includes a tracking area identifier TAI of the geographic location of the terminal, the first network side device determines that the tracking area identified by the TAI is the first target TA. And under the condition that the position information does not comprise the TAI of the geographic position of the terminal, the first network side equipment acquires at least one tracking area code TAC, and determines the first target TA according to 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 according to coverage information of the network, for example, ephemeris information, and perform paging if the first target TA is covered by the network. The network may be a satellite network. The page includes a first page, or a non-first page.

In this embodiment, a first network side device obtains location information of a terminal; the first network side equipment determines a first target tracking area TA according to the position information; the first network side device performs paging in the case that the first target TA is covered by the network. By the mode, the first network side equipment can determine the first target TA by acquiring the position information of the terminal, and execute paging under the condition that the first target TA is covered by the network, so that the terminal can be effectively ensured to receive the paging message, and the paging success rate is improved.

In one embodiment of the present application, if the location information includes a TAI of a geographic location of the terminal, after the first network side device performs paging if the first target TA is covered by a network, the method further includes:

under the condition that the first network side equipment fails to page on the first target TA, the first network side equipment determines a second target TA according to the at least one TAC;

And the first network side equipment executes paging on the second target TA under the condition that the second target TA is covered by the network.

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

at least one tracking area code TAC in a registered public land mobile network RPLMN indicated by a serving cell of the terminal; or at least one TAC of a public land mobile network PLMN equivalent to said RPLMN; wherein the at least one TAC is in a registration area RA of the terminal.

And determining the TA covered by the network in the at least one TAC as the second target TA, and executing paging on the second target TA by the second network side equipment.

In one embodiment of the present application, the determining, by the first network side device, the first target tracking area TA according to the location information includes:

under the condition that the position information does not comprise the TAI of the geographic position of the terminal, the first network side equipment acquires at least one tracking area code TAC;

The first network side device determines the first target TA according to 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 a registered public land mobile network (Registered Public Land Mobile Network, RPLMN) indicated by a serving cell of the terminal; or at least one TAC of a public land mobile network PLMN equivalent to said RPLMN; wherein the at least one TAC is in a registration area RA of the terminal.

The communication method provided by the present application is exemplified below.

Fig. 7b is a schematic diagram illustrating interaction between a terminal and a network device. In this embodiment, the coverage information of the cell in which the terminal is located changes, and the terminal moves from the first cell to the second cell, where 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 is different from that of the second cell, the terminal triggers a registration request, sends the registration request to the RAN2, and the RAN2 sends initialization terminal information to the AMF; if the initialization terminal information does not carry the coverage information of the target network, the AMF sends query information to the RAN2, wherein the query information is used for querying the coverage information of the target network, and the RAN2 feeds back the coverage information to the AMF. After obtaining the target duration, the AMF sends a registration success message to the terminal, and the registration success message carries the target duration, namely the value of T3324.

Fig. 7c is a schematic diagram illustrating interaction between a terminal and a network side device. In this embodiment, the coverage information of the cell in which the terminal is located changes, but the network information of the network of the coverage cell changes, and the changed network is the target network. After determining that the coverage information of the cells is different, the terminal triggers a registration request, sends the registration request to the RAN1, and the RAN1 sends initialization terminal information to the AMF, if the initialization terminal information carries the coverage information of the target network, the AMF determines the target duration according to the coverage information; if the initialization terminal information does not carry the coverage information of the target network, the AMF sends query information to the RAN2, wherein the query information is used for querying the coverage information of the target network, and the RAN2 feeds back the coverage information to the AMF. After obtaining the target duration, the AMF sends a registration success message to the terminal, and the registration success message carries the target duration, namely the value of T3324.

Fig. 7d is a schematic diagram illustrating interaction between a terminal and a network device. And before the AMF releases the UE CONTEXT, acquiring a TA-position report corresponding to the actual geographic position of the UE.

Before sending the terminal context release order message to RAN1, the AMF will initiate a location reporting procedure to request the last known location of the terminal. In the case of satellite access, RAN1 provides all broadcasted TAIs of the selected PLMN to the AMF as part of the user location information (User Location Information, ULI). If the RAN1 can determine the TAI of the geographical location where the UE is located, the RAN1 also informs the AMF via a location report.

After acquiring the TAI where the geographic location of the terminal is located, the AMF sends a terminal context release command message (N2 UE Context Release Command) to the RAN1, and the RAN1 triggers connection release and sends a terminal context release complete (N2 UE Context Release Complete) message to the AMF.

If the AMF knows the TAI of the terminal's geographical location, then that TAI is taken as the last known TAI. The AMF determines that the TAI is in the coverage area when PAGING according to the ephemeris information, and then Pages (PAGING) firstly in the TA identified by the TAI;

if the AMF does not know the TAI of the geographic location of the terminal, the TAI satisfying the following conditions is taken as the latest known TAI:

one or more TACs of the RPLMN indicated by the serving cell of the UE, or one or more TACs of the PLMN equivalent to the RPLMN, which are in the registration area (Registration Area, RA) of the UE. The AMF determines from the ephemeris information that the TACs are in the coverage area of the network when paging, and pages first among the TAs that the TACs include.

Fig. 7e is a schematic diagram illustrating interaction between a terminal and a network device. The AMF initiates an LCS procedure to request the location of the terminal before sending a terminal context release order message to the RAN 1. Through the LCS procedure, the AMF obtains the TA of the geographic location of the UE, and other procedures may be described with reference to fig. 7d, which is not described herein.
