Abstract

Claims (31)

1 . A communication method, applied to a first network device, the method comprising:

sending configuration information of a first communication resource to a first terminal device, wherein the first terminal device provides a relay service for a second terminal device, the first communication resource is used for communication between the first terminal device in a connected state and the first network device; and

broadcasting, through the first communication resource, a paging message used for paging the second terminal device, wherein reception of the paging message by the first terminal device causes the first terminal device to send second indication information to the second terminal device, the second indication information indicating that the second terminal device is paged.

2 . The communication method according to claim 1 , wherein the first terminal device is a relay terminal device and the second terminal device is a remote terminal device.

3 . The communication method according to claim 1 further comprising:

receiving first information from the first terminal device, wherein the first information indicates that a sidelink connection exists between the first terminal device and the second terminal device.

4 . The communication method according to claim 3 , wherein the first information is a dedicated information element.

5 . The communication method according to claim 3 , wherein the first information comprises identifier information of the second terminal device.

6 . The communication method according to claim 5 , wherein the paging message comprises a paging message related to the identifier information of the second terminal device.

7 . The communication method according to claim 5 , wherein the identifier information of the second terminal device comprises a 5G s-temporary mobile subscriber identity (5G-S-TMSI) or a full inactive radio network temporary identifier full (I-RNTI).

8 . A communication method, applied to a first terminal device, the method comprising:

receiving configuration information of a first communication resource from a first network device, wherein the first terminal device provides a relay service for a second terminal device, wherein the first communication resource is used for communication between the first terminal device in a connected state and the first network device;

configuring the first communication resource based on the configuration information;

receiving a paging message based on the first communication resource; and

sending second indication information to the second terminal device, wherein the second indication information indicates that the second terminal device is paged.

9 . The communication method according to claim 8 , further comprising:

receiving a radio resource control (RRC) message from the first network device, wherein the RRC message comprises the paging message.

10 . The communication method according to claim 8 , further comprising:

sending first information to the first network device, wherein the first information indicates that a sidelink connection exists between the first terminal device and the second terminal device.

11 . The communication method according to claim 10 , wherein the first information comprises identifier information of the second terminal device.

12 . The communication method according to claim 11 , wherein the paging message comprises a paging message related to the identifier information of the second terminal device.

13 . The communication method according to claim 11 , wherein the identifier information of the second terminal device comprises a 5G s-temporary mobile subscriber identity (5G-S-TMSI) or a full inactive radio network temporary identifier full (I-RNTI).

14 . A communication apparatus, applied to a first terminal device, the apparatus comprising a communication unit and a processing unit;

the communication unit is configured to receive configuration information of a first communication resource from a first network device, wherein the first terminal device provides a relay service for a second terminal device, wherein the first communication resource is used for communication between the first terminal device in a connected state and the first network device;

the processing unit is configured to configure the first communication resource based on the configuration information;

the communication unit is configured to receive a paging message based on the first communication resource; and

the communication unit is further configured to send second indication information to the second terminal device, wherein the second indication information indicates that the second terminal device is paged.

15 . The communication apparatus according to claim 14 , wherein the communication unit is further configured to send first information to the first network device, wherein the first information indicates that a sidelink connection exists between the first terminal device and the second terminal device.

16 . The communication apparatus according to claim 15 , wherein the first information comprises identifier information of the second terminal device.

17 . The communication method according to claim 16 , wherein the paging message comprises a paging message related to the identifier information of the second terminal device.

18 . The communication apparatus according to claim 16 , wherein the identifier information of the second terminal device comprises a 5G s-temporary mobile subscriber identity (5G-S-TMSI) or a full inactive radio network temporary identifier full (I-RNTI).
