Abstract

Embodiments provide a device discovery method which relates to the field of communications technologies. The method includes: receiving, by a server, a discovery request, where the discovery request is used to request to discover another UE near a user equipment UE, and the discovery request includes a discovery category indication; generating discovery configuration information according to the discovery category indication, and sending the discovery configuration information to a base station or the UE, where the discovery configuration information is used to configure a parameter that is used when the base station or the UE detects another nearby UE; and receiving a discovery result sent by the base station or the UE.

Claims

1. An apparatus, comprising:

a non-transitory storage medium storing executable instructions; and

a processor;

wherein the executable instructions, when executed by the processor, cause the apparatus to;

receive a discovery request message, wherein the discovery request message requests to discover a second user equipment (UE) near a first UE, and wherein the discovery request message comprises a discovery category indication;

generate discovery configuration information according to the discovery category indication;

send the discovery configuration information to the first UE, wherein the discovery configuration information is used by the first UE to configure a parameter that is used when the first UE detects the second UE; and

receive a discovery result sent by the first UE.

2. The apparatus according to claim 1, wherein the discovery category indication comprises a service requirement indication, a discovery range indication, a target UE list, a capability requirement indication, or a target group indication.

3. The apparatus according to claim 2, wherein the executable instructions, when executed by the processor, further cause the apparatus to:

before the discovery request message is received, receive capability information of the first UE when the first UE registers with a server;

or

before the discovery request message is received, receive group information of the first UE when the first UE registers with the server.

4. The apparatus according to claim 3, wherein the discovery category indication comprises the capability requirement indication or the target group indication;

and

wherein the executable instructions, when executed by the processor, further cause the apparatus to;

generate the discovery configuration information according to the capability requirement indication or the target group indication comprised in the discovery category indication, and according to the capability information or the group information of the first UE that is received when the first UE registers with the server.

5. The apparatus according to claim 1, wherein the discovery result comprises a list of UEs detected by a base station or the first UE, wherein the UEs comprised in the list of UEs detected by the base station are each located near the first UE and each respectively meet a requirement of the discovery category indication.

6. The apparatus according to claim 1, wherein the executable instructions, when executed by the processor, further cause the apparatus to:

send the discovery configuration information to a base station to send to the first UE.

7. The apparatus according to claim 1, wherein the executable instructions, when executed by the processor, further cause the apparatus to:

send the discovery configuration information directly to the first UE.

8. An apparatus, comprising:

a storage medium storing executable instructions; and

a processor;

wherein the executable instructions, when executed by the processor, cause the apparatus to;

send a discovery request message to a server, wherein the discovery request message requests to discover a second UE near a first UE, and the discovery request message comprises a discovery category indication;

receive discovery configuration information from the server, wherein the discovery configuration information is used to configure a parameter that is used when the first UE detects the second UE; and

discover the second UE according to the discovery configuration information, to obtain a discovery result, wherein the second UE is under control of the server.

9. The apparatus according to claim 8, wherein the discovery category indication comprises a service requirement indication, a discovery range indication, a target UE list, a capability requirement indication, or a target group indication.

10. The apparatus according to claim 8, wherein the discovery result comprises a list of UEs detected by the first UE, wherein each UE comprised in the list of UEs is located near the first UE and each UE comprised in the list of UEs meets a requirement of the discovery category indication.

11. A non-transitory computer-readable storage medium comprising executable instructions stored thereon, wherein the executable instructions, when executed by a computer, cause the computer to:

receive a discovery request message, wherein the discovery request message requests to discover a second user equipment (UE) near a first UE, and wherein the discovery request message comprises a discovery category indication;

generate discovery configuration information according to the discovery category indication;

send the discovery configuration information to the first UE, wherein the discovery configuration information is used by the first UE to configure a parameter that is used when the first UE detects the second UE; and

receive a discovery result sent by the first UE.

12. The non-transitory computer-readable storage medium according to claim 11, wherein the discovery category indication comprises a service requirement indication, a discovery range indication, a target UE list, a capability requirement indication, or a target group indication.

13. The non-transitory computer-readable storage medium according to claim 12, wherein the executable instructions, when executed by a computer, further cause the computer to:

before the discovery request message is received, receive capability information of the first UE when the first UE registers with a server;

or

before the discovery request message is received, receive group information of the first UE when the first UE registers with the server.

14. The non-transitory computer-readable storage medium according to claim 13, wherein the discovery category indication comprises the capability requirement indication or the target group indication;

and

wherein the executable instructions, when executed by a computer, further cause the computer to;

generate the discovery configuration information according to the capability requirement indication or the target group indication comprised in the discovery category indication, and according to the capability information or the group information of the first UE that is received when the first UE registers with the server.

15. The non-transitory computer-readable storage medium according to claim 11, wherein the discovery result comprises a list of UEs detected by a base station or the first UE, wherein the UEs comprised in the list of UEs detected by the base station are each located near the first UE and each respectively meet a requirement of the discovery category indication.

16. The non-transitory computer-readable storage medium according to claim 11, wherein the executable instructions, when executed by a computer, further cause the computer to:

send the discovery configuration information to a base station to send to the first UE.

17. The non-transitory computer-readable storage medium according to claim 11, wherein the executable instructions, when executed by a computer, further cause the computer to:

send the discovery configuration information directly to the first UE.

18. A non-transitory computer-readable storage medium, comprising executable instructions stored thereon, wherein the executable instructions, when executed by a computer, cause the computer to:

send a discovery request message to a server, wherein the discovery request message requests to discover a second user equipment (UE) near a first UE, and the discovery request message comprises a discovery category indication;
