Abstract

A user equipment (UE) configured to provide a service type indicator in a user assistance information (UAI) message to a base station of a telecommunication network is described herein. The service type indicator indicates a type of a network-using service active on the UE. A base station, as also described herein, then takes action based on resources available to the base station and on the service type indicator received from the UE in the UAI message.

First claim

What is claimed is:

1 . A user equipment (UE) comprising:
a processor; and a plurality of programming instructions that, when executed by the processor, perform operations including:
determining that a service which utilizes a telecommunication network is active on the UE; and
providing a service type indicator in a user assistance information (UAI) message to a base station of the telecommunication network, the service type indicator indicating a type of the service.

2 . The UE of claim 1 , wherein the service is an extended reality (XR) service and the service type indicator indicates that the service is an XR service.

3 . The UE of claim 1 , wherein providing the service type indicator in the UAI message comprises providing multiple service type indicators for multiple services that are active on the UE.

4 . The UE of claim 1 , wherein the providing includes providing, in a traffic characteristics field of the UAI message, indication(s) of desired uplink or downlink bandwidth.

5 . The UE of claim 1 , wherein the determining and the providing are in response to an activation of the service on the UE.

6 . The UE of claim 1 , wherein the providing is performed after transmission from the UE of a radio resource control (RRC) connection request and before receiving an RRC reconfiguration message.

7 . The UE of claim 1 , wherein the providing is performed conditionally based on a base station type of the base station.

8 . A method comprising:
receiving, by a base station connected to a user equipment (UE), a user assistance information (UAI) message; determining, by the base station, that the UAI message includes a service type indicator indicating that a service which utilizes a telecommunication network is active on the UE; and taking an action, by the base station, based on resources available to the base station and on the service type indicator.

9 . The method of claim 8 , wherein the service is an extended reality (XR) service and the service type indicator indicates that the service is an XR service.

10 . The method of claim 8 , wherein the receiving comprises receiving multiple service type indicators for multiple services that are active on the UE, the determining comprises determining that the UAI message includes the received multiple service type indicators, and the taking the action comprises taking the action based on the resources and on the multiple service type indicators.

11 . The method of claim 8 , wherein the determining comprises determining that the UAI message includes traffic characteristics indicating desired uplink or downlink bandwidth for the UE and taking the action comprises taking the action based on the resources, the service type indicator, and the traffic characteristics.

12 . The method of claim 8 , wherein the taking the action includes determining that insufficient resources are available to the base station and the action is one of terminating a connection with the UE or handing the UE off to another base station or wireless access point.

13 . The method of claim 8 , wherein the taking the action includes determining that sufficient resources are available to the base station and the action is proceeding with establishing a protocol data unit (PDU) session between the UE and a core network of the telecommunication network to use for the service.

14 . The method of claim 8 , wherein the action includes adaptation of network traffic between the UE and the base station for lower resolution service.

15 . The method of claim 8 , wherein the taking the action includes a radio resource control (RRC) handler of the base station communicating with a lower layer of a communication stack to determine if the resources available to the base station are sufficient for the service.

16 . A non-transitory computer storage medium having a plurality of programming instructions stored thereon that, when executed by a user equipment (UE), cause the UE to perform operations comprising:
determining that an extended reality (XR) service which utilizes a telecommunication network is active on the UE; and providing a service type indicator in a user assistance information (UAI) message to a base station of the telecommunication network, the service type indicator indicating that the XR service is active on the UE.

17 . The non-transitory computer storage medium of claim 16 , wherein providing the service type indicator in the UAI message comprises providing multiple service type indicators for multiple services that are active on the UE.

18 . The non-transitory computer storage medium of claim 16 , wherein the providing includes providing, in a traffic characteristics field of the UAI message, indication(s) of desired uplink or downlink bandwidth.

19 . The non-transitory computer storage medium of claim 16 , wherein the determining and the providing are in response to an activation of the XR service on the UE.

20 . The non-transitory computer storage medium of claim 16 , wherein the providing is performed conditionally based on a base station type of the base station.
