sending, to the first terminal, a paging message at the paging position, wherein the paging message carries the terminal identifier of the second terminal; wherein
the paging position comprises at least one of: a paging frame; a paging occasion; or a frequency-domain position.
2. The paging method according to claim 1 , wherein
the first terminal resides in a cellular network, or communicates with a cellular network device, or is in an inactive state in a cellular network; and
the first terminal and the second terminal communicate with each other through a non-cellular network.
3. The paging method according to claim 1 , wherein there is a binding relationship between the first terminal and the second terminal, and the method further comprises:
obtaining the binding relationship between the first terminal and the second terminal from a core network entity.
4. The paging method according to claim 1 , further comprising:
assigning a same terminal identifier or similar terminal identifiers to the first terminal and the second terminal.
5. The paging method according to claim 1 , wherein before the sending a paging message, the method further comprises: obtaining at least one of:
paging information of the first terminal; or
paging information of the second terminal.
6. The paging method according to claim 5 , wherein the paging information of the first terminal or the paging information of the second terminal comprises at least one of:
the terminal identifier of the first terminal;
application layer configuration information of the first terminal;
access stratum configuration information of the first terminal;
the terminal identifier of the second terminal;
application layer configuration information of the second terminal; or
access stratum configuration information of the second terminal; wherein
the application layer configuration information comprises an internet protocol (IP) layer identifier; and
the access stratum configuration information comprises an access network side identifier.
7. The paging method according to claim 5 , wherein the paging information is obtained through at least one of:
receiving the paging information of the first terminal and/or the paging information of the second terminal reported by the first terminal;
receiving the paging information of the first terminal and/or the paging information of the second terminal reported by the second terminal; or
obtaining the paging information of the first terminal and/or the paging information of the second terminal from a core network entity.
8. A paging method, performed by a first terminal, wherein in a case where the first terminal resides in a cellular network, communicates with a cellular network device, or is in an inactive state in a cellular network, the method comprises:
receiving, by the first terminal, a first paging message sent by a network side device, wherein the first paging message carries a terminal identifier of a second terminal, a paging position of the first paging message is determined based on a paging terminal identifier, and the paging terminal identifier is the terminal identifier of the second terminal; wherein the paging position comprises at least one of: a paging frame; a paging occasion; or a frequency-domain position;
wherein in a case where the first terminal and the second terminal communicate with each other through a non-cellular network, the method further includes:
sending, by the first terminal, the first paging message to the second terminal through the non-cellular network.
9. The paging method according to claim 8 , wherein there is a binding relationship between the first terminal and the second terminal.
10. The paging method according to claim 9 , wherein a paging terminal identifier used by the first terminal to determine the paging position is same as a paging terminal identifier used by the second terminal to determine the paging position.
11. The paging method according to claim 8 , wherein before the receiving, by the first terminal, a paging message sent by a network side device, the method further comprises:
sending, by the first terminal, paging information of the first terminal and/or paging information of the second terminal to the network side device.
12. The paging method according to claim 11 , further comprising:
sending, by the second terminal, the paging information of the first terminal and/or the paging information of the second terminal to the network side device.
13. The paging method according to claim 12 , wherein before the sending, by the first terminal, the paging information of the second terminal to the network side device, the method further comprises:
obtaining, by the first terminal, the paging information of the second terminal.
14. A network side device, used to page a first terminal, wherein the network side device comprises a processor, a memory, and a computer program stored in the memory and executable on the processor, and the computer program, when executed by the processor, causes the network side device to perform:
determining a paging position of the first terminal and a second terminal based on a paging terminal identifier, wherein the paging terminal identifier is a terminal identifier of the second terminal; and
sending, to the first terminal, a paging message at the paging position, wherein the paging message carries the terminal identifier of the second terminal; wherein
the paging position comprises at least one of: a paging frame; a paging occasion; or a frequency-domain position.
15. The paging method according to claim 1 , wherein the terminal identifier comprises some or all bits of at least one of following:
an international mobile equipment identity (IMEI);
an international mobile subscriber identity (IMSI);
a temporary mobile subscriber identity (S-TMSI); or
a radio network temporary identifier (RNTI).
16. The paging method according to claim 11 , wherein the paging information of the first terminal or the paging information of the second terminal comprises at least one of:
the terminal identifier of the first terminal;
application layer configuration information of the first terminal;
access stratum configuration information of the first terminal;
the terminal identifier of the second terminal;
application layer configuration information of the second terminal; or
access stratum configuration information of the second terminal; wherein
the application layer configuration information comprises an internet protocol (IP) layer identifier; and
the access stratum configuration information comprises an access network side identifier.
17. The paging method according to claim 8 , wherein the terminal identifier comprises some or all bits of at least one of following:
an international mobile equipment identity (IMEI);
an international mobile subscriber identity (IMSI);
