Method for processing paging cause and apparatus, communication device, and storage medium

1 . A method for processing a paging cause, performed by a base station, and comprising:

receiving a request message requesting the paging cause sent by a specific terminal; and

sending the paging cause to the specific terminal,

wherein the request message requesting the paging cause is sent by the specific terminal to the base station based on a second user identity module of the specific terminal in response to the specific terminal establishing a connection with another base station based on a first user identity module.

2 . The method according to claim 1 , wherein the specific terminal at least comprises:

a terminal having at least two subscriber identity modules (SIMs).

3 . The method according to claim 2 ,

wherein the sending of the paging cause to the specific terminal comprises:

sending the paging cause to the specific terminal based on the request message.

4 . The method according to claim 2 , wherein the sending of the paging cause to the specific terminal comprises:

sending the paging cause to the specific terminal based on a protocol provision; or

sending the paging cause to the specific terminal based on a pre-negotiation between the base station and the specific terminal; or

sending the paging cause to the specific terminal based on a paging message received from a core network.

5 . The method according to claim 2 , wherein the sending of the paging cause to the specific terminal comprises:

in response to the base station supporting the sending of the paging cause, sending the paging cause to the specific terminal.

6 . The method according to claim 1 ,

wherein the sending of the paging cause to the specific terminal comprises:

sending the paging cause to the specific terminal based on the request message.

7 . The method according to claim 1 , wherein the sending of the paging cause to the specific terminal comprises at least one of the following:

sending the paging cause to the specific terminal based on a protocol provision;

sending the paging cause to the specific terminal based on a pre-negotiation between the base station and the specific terminal; or

sending the paging cause to the specific terminal based on a paging message received from a core network.

8 . The method according to claim 1 , wherein the sending of the paging cause to the specific terminal comprises:

in response to the base station supporting the sending of the paging cause, sending the paging cause to the specific terminal.

9 . The method according to claim 8 , wherein the method further comprises:

sending capability information about whether the base station supports the sending of the paging cause.

10 . The method according to claim 9 , wherein

the capability information is carried by a system message; or

the capability information is carried by Radio Resource Control RRC signaling.

11 . The method according to claim 10 , wherein the system message comprises:

a minimum system message; or

a system message block other than the minimum system message.

12 . A method for processing a paging cause, performed by a specific terminal, and comprising:

sending a request message requesting the paging cause; and

receiving the paging cause sent by a base station,

wherein the sending of the request message requesting the paging cause comprises:

in response to the specific terminal establishing a connection with another base station based on a first user identity module, sending the request message requesting the paging cause to the base station based on a second user identity module of the specific terminal.

13 . The method according to claim 12 , wherein the method further comprises:

receiving capability information indicating whether the base station supports the sending of the paging cause, wherein the request message is sent after the base station is determined based on the capability information to support the sending of the paging cause.

14 . The method according to claim 12 , wherein, the sending of the request message requesting the paging cause to the base station based on the second user identity module of the specific terminal, in response to the specific terminal establishing the connection with the other base station based on the first user identity module, comprises:

in response to the specific terminal establishing the connection with the other base station based on the first user identity module and transmitting on the connection, sending the request message requesting the paging cause to the base station based on the second user identity module of the specific terminal.

15 . The method according to claim 14 , wherein the method further comprises:

in response to the specific terminal establishing the connection with the other base station based on the first user identity module, determining whether to respond to the paging message of the base station based on the paging cause sent by the base station.

16 . The method according to claim 12 , wherein the method further comprises:

in response to the specific terminal establishing the connection with the other base station based on the first user identity module, determining whether to respond to the paging message of the base station based on the paging cause sent by the base station.

17 . A communication device, comprising: a processor, a transceiver, a memory, and an executable program stored on the memory and configured to be executed by the processor, wherein

the processor is configured, when executing the executable program, to perform the method for processing a paging cause according to claim 12 .

18 . A communication device, comprising: a processor, a transceiver, a memory, and an executable program stored on the memory and configured to be executed by the processor, wherein

the processor is configured, when executing the executable program, to perform a method for processing a paging cause, comprising:

receiving a request message requesting the paging cause sent by a specific terminal; and

sending the paging cause to the specific terminal, wherein the request message requesting the paging cause is sent by the specific terminal to the communication device based on a second user identity module of the specific terminal in response to the specific terminal establishing a connection with another communication device based on a first user identity module.
