Abstract

An identifier allocation method includes receiving, by a first core network device, a first request from a terminal device, allocating, by the first core network device, a first capability information identifier, and sending, by the first core network device, a first response to the terminal device, where the first response carries the first capability information identifier.

First claim

What is claimed is:

1. A method implemented by a terminal device, wherein the method comprises:
sending a first request to a core network device, wherein the first request comprises a first indication indicating to set first capability information and to add storage of a group of capability information of the terminal device;
setting the capability information by performing an addition operation; and
receiving, from the core network device in response to the first request, a first response comprising a first capability information identifier corresponding to first capability information stored on the terminal device.

2. The method of claim 1 , further comprising:
sending a second request to the core network device; and
receiving, from the core network device in response to the second request, a second response comprising a capability information identifier count.

3. The method of claim 1 , wherein the first request comprises the first capability information.

4. The method of claim 3 , further comprising storing a mapping relationship between the first capability information and the first capability information identifier.

5. The method of claim 1 , further comprising:
receiving a third request from an access network device; and
sending the first capability information to the access network device in response to the third request.

6. The method of claim 1 , further comprising sending, to the core network device, a fourth request comprising a second capability information identifier, wherein the second capability information identifier corresponds to second capability information of the terminal device.

7. The method of claim 1 , further comprising storing mapping relationships between at least two groups of capability information of the terminal device and capability information identifiers.

8. The method of claim 1 , wherein the first response further comprises a capability information identifier count.

9. The method of claim 1 , further comprising sending the first request to the core network device when a preset database of the terminal device does not comprise an identifier corresponding to first capability information, wherein the preset database stores a preconfigured mapping relationship between a plurality of group of capability information and identifiers.

10. The method of claim 1 , wherein the first request comprises an indication indicating that the terminal device supports radio capability signaling.

11. A terminal device comprising:
a memory configured to store instructions; and
a processor coupled to the memory, wherein the instructions cause the processor to be configured to:
send a first request to a first core network device, wherein the first request comprises a first indication indicating to set capability information of the terminal device and to add storage of a group of capability information of the terminal device;
set the capability information by performing an addition operation; and
receive, from the first core network device in response to the first request, a first response comprising a capability information identifier corresponding to first capability information stored on the terminal device.

12. The terminal device of claim 11 , wherein the instructions cause the processor to be configured to:
send a second request to the core network device; and
receive, from the core network device in response to the second request, a second response comprising a capability information identifier count.

13. The terminal device of claim 11 , wherein the first response further comprises a capability information identifier count.

14. The terminal device of claim 11 , wherein the first request comprises the first capability information.

15. The terminal device of claim 14 , wherein the instructions cause the processor to be configured to store a mapping relationship between the first capability information and the first capability information identifier.

16. The terminal device of claim 11 , wherein the instructions cause the processor to be configured to:
receive a third request from an access network device; and
send the first capability information to the access network device in response to the third request.

17. The terminal device of claim 11 , wherein the instructions cause the processor to be configured to send, to the core network device, a fourth request comprising a second capability information identifier, wherein the second capability information identifier corresponds to second capability information of the terminal device.

18. A method implemented by a first core network device, wherein the method comprises:
receiving a first request from a terminal device, wherein the first request comprises a first indication indicating to set capability information of the terminal device and to add storage of a group of capability information of the terminal device;
setting the capability information by performing an addition operation;
allocating a capability information identifier to the terminal in response to the first request; and
sending a first response comprising the capability information identifier to the terminal device.

19. The method of claim 18 , further comprising:
receiving a second request from the terminal device;
allocating a capability information identifier count to the terminal device in response to the second request; and
sending a second response comprising the capability information identifier count to the terminal device.

20. The method of claim 18 , wherein the first request comprises capability information of the terminal device, and wherein the method further comprises allocating the capability information identifier to the capability information.
