Abstract

This disclosure relates to techniques for reducing signaling overhead associated with signaling the capability of a wireless device and/or other messages. Among various possibilities, tags and/or compression may be used. Additionally, techniques for enhanced security and signaling between network devices are disclosed.

First claim

What is claimed is:

1. A user equipment device (UE), comprising:
a radio; and
a processor operably coupled to the radio, wherein the processor is configured to cause the UE to:
establish communication with a base station of a cellular network;
transmit a first capability identifier tag to the base station, wherein the first capability identifier tag comprises a combination of a device hash identifier and a capability hash identifier and is set to a particular value to indicate a request to re-initiate a capability procedure;
receive, from the base station, a capability inquiry in response to the first capability identifier tag;
transmit a second capability identifier tag, different from the first capability identifier tag, of the UE to the base station, wherein the second capability identifier tag includes an identification associated with a manufacturer of the UE device, wherein the second capability identifier tag relates to capability information for the UE stored at the cellular network; and
communicate, with the base station, according to the capability information.

2. The UE of claim 1 , wherein the second capability identifier tag of the UE is transmitted in response to the capability inquiry.

3. The UE of claim 1 , wherein the capability inquiry comprises an indication of a requested frequency band, wherein the second capability identifier tag is associated with the requested frequency band.

4. The UE of claim 1 , wherein the second capability identifier tag is a unique identifier for the capability information.

5. The UE of claim 1 , wherein the second capability identifier tag relates to capabilities of the UE for communication on one or more frequency bands and/or combinations of frequency bands.

6. The UE of claim 1 , wherein the second capability identifier tag is based in part on a current configuration of the UE.

7. The UE of claim 1 , wherein the second capability identifier tag is smaller than the capability information.

8. An apparatus, comprising:
a processor configured to cause a user equipment device (UE) to:
establish communication with a base station of a cellular network;
transmit a first capability identifier to the base station, wherein the first capability identifier comprises a combination of a device hash identifier and a capability hash identifier and is set to a particular value to indicate a request to re-initiate a capability procedure;
receive, from the base station, a capability inquiry in response to the first capability identifier;
transmit a second capability identifier, different from the first capability identifier, of the UE to the base station, wherein the second capability identifier includes an identification associated with a manufacturer of the device, wherein the second capability identifier relates to capability information for the UE stored at the cellular network; and
communicate, with the base station, according to the capability information.

9. The apparatus of claim 8 , wherein the second capability identifier of the UE is transmitted in response to the capability inquiry.

10. The apparatus of claim 8 , wherein the capability inquiry comprises an indication of a requested frequency band, wherein the second capability identifier is associated with the requested frequency band.

11. The apparatus of claim 8 , wherein the second capability identifier is a unique identifier for the capability information.

12. The apparatus of claim 8 , wherein the second capability identifier relates to capabilities of the UE for communication on one or more frequency bands and/or combinations of frequency bands.

13. The apparatus of claim 8 , wherein the second capability identifier is based in part on a current configuration of the UE.

14. The apparatus of claim 8 , wherein the second capability identifier is smaller than the capability information.

15. An apparatus, comprising:
a processor configured to cause a base station of a network to:
establish communication with a user equipment device (UE);
receive a first capability identifier from the UE, wherein the first capability identifier comprises a combination of a device hash identifier and a capability hash identifier and is set to a particular value indicating a request to re-initiate a capability procedure;
transmit, to the UE, a capability inquiry in response to the first capability identifier;
receive, from the UE, a second capability identifier of the UE that is different than the first capability identifier, wherein the second capability identifier includes an identification associated with a manufacturer of the device, wherein the second capability identifier relates to capability information for the UE stored at the network; and
communicate, with the UE, according to the capability information.

16. The apparatus of claim 15 , wherein the second capability identifier of the UE is in response to the capability inquiry.

17. The apparatus of claim 15 , wherein the second capability identifier is a unique identifier for the capability information.

18. The apparatus of claim 15 , wherein the second capability identifier relates to capabilities of the UE for communication on one or more frequency bands and/or combinations of frequency bands.

19. The apparatus of claim 15 , wherein the second capability identifier is based in part on a current configuration of the UE.

20. The apparatus of claim 15 , wherein the second capability identifier is smaller than the capability information.
