Abstract

This disclosure relates to dynamic baseband management for a wireless device. The wireless device may be an accessory device. The accessory device may determine whether it has a short-range wireless communication link with a companion device. The accessory device may determine one or more proximity metrics relating to the companion device. The accessory device may further determine one or more metrics associated with user settings, user activity and/or application activity at the wireless device. The wireless device may select a (e.g., full, limited, or off) baseband operating mode based on any or all of these considerations.

First claim

What is claimed is:

1. An apparatus, comprising:
a processor configured to cause an accessory wireless device to:
determine whether the accessory wireless device is operating in a relay mode using a short-range wireless communication link with a companion user equipment device (UE), wherein operating in the relay mode includes using cellular functionality of the companion UE to communicate with a cellular base station;
determine one or more metrics associated with user activity or application activity at the accessory wireless device; and
determine whether to limit functionality of cellular communication circuitry of the accessory wireless device based at least in part on (a) whether the accessory wireless device is operating in the relay mode using the short-range wireless communication link and (b) the one or more metrics associated with user activity or application activity at the accessory wireless device.

2. The apparatus of claim 1 ,
wherein, if the accessory wireless device is operating in the relay mode using the short-range wireless communication link, the processor is further configured to cause the accessory wireless device to:
determine a type of the short-range wireless communication link; and
determine whether to limit functionality of the cellular communication circuitry further based at least in part on the type of the short-range wireless communication link.

3. The apparatus of claim 1 ,
wherein if the accessory wireless device is not operating in the relay mode using the short-range wireless communication link, the processor is further configured to cause the accessory wireless device to:
determine a length of time for which the accessory wireless device has not had a short-range wireless communication link with a companion UE; and
determine whether to limit functionality of the cellular communication circuitry further based at least in part on the length of time for which the accessory wireless device has not had a short-range wireless communication link with a companion UE.

4. The apparatus of claim 1 ,
wherein the one or more metrics associated with user activity or application activity at the accessory wireless device comprise at least whether any application executing at the accessory wireless device is currently actively performing wireless communication.

5. The apparatus of claim 1 ,
wherein the one or more metrics associated with user activity or application activity at the accessory wireless device comprise one or more of:
a physical position of the accessory wireless device relative to a user of the accessory wireless device;
a screen state of the accessory wireless device; or
one or more user settings relating to a preferred operating mode.

6. The apparatus of claim 1 , wherein the processor is further configured to cause the accessory wireless device to:
determine whether the accessory wireless device has a subscriber identity module that provides a cellular service plan; and
determine whether to limit functionality of the cellular communication circuitry further based at least in part on whether the accessory wireless device has a subscriber identity module that provides a cellular service plan.

7. A method, comprising:
at an accessory wireless device:
determining whether the accessory wireless device is operating in a relay mode using a short-range wireless communication link with a companion user equipment device (UE), wherein operating in the relay mode includes using cellular functionality of the companion UE to communicate with a cellular base station;
determining one or more metrics associated with user activity or application activity at the accessory wireless device; and
determining whether to limit functionality of cellular communication circuitry of the accessory wireless device based at least in part on (a) whether the accessory wireless device is operating in the relay mode using the short-range wireless communication link and (b) the one or more metrics associated with user activity or application activity at the accessory wireless device.

8. The method of claim 7 , wherein, if the accessory wireless device is operating in the relay mode using the short-range wireless communication link, the method further comprises:
determining a type of the short-range wireless communication link; and
determining whether to limit functionality of the cellular communication circuitry further based at least in part on the type of the short-range wireless communication link.

9. The method of claim 7 , wherein if the accessory wireless device is not operating in the relay mode using the short-range wireless communication link, the method further comprises:
determining a length of time for which the accessory wireless device has not operated in the relay mode; and
determining whether to limit functionality of the cellular communication circuitry further based at least in part on the length of time for which the accessory wireless device has not had a short-range wireless communication link with a companion wireless device.

10. The method of claim 7 , wherein the one or more metrics associated with user activity or application activity at the accessory wireless device comprise at least whether any application executing at the accessory wireless device is currently actively performing wireless communication.

11. The method of claim 7 , wherein the one or more metrics associated with user activity or application activity at the accessory wireless device include one or more of:
a physical position of the accessory wireless device relative to a user of the accessory wireless device;
a screen state of the accessory wireless device; or
one or more user settings relating to a preferred operating mode.

12. The method of claim 7 , wherein the method further comprises:
determining whether the accessory wireless device has a subscriber identity module that provides a cellular service plan; and
determining whether to limit functionality of the cellular communication circuitry further based at least in part on whether the accessory wireless device has a subscriber identity module that provides a cellular service plan.

13. A mobile device comprising:
a radio; and
a processor operably coupled to the radio and configured to cause the mobile device to:
determine that the mobile device does not have a short-range wireless communication link with a companion user equipment device (UE) useable for operating in a relay mode, wherein operating in said relay mode includes using cellular functionality of the companion UE to communicate with a cellular base station;
in response to the determination that the mobile device does not have the short-range wireless communication link with the companion UE useable for operating in the relay mode, determine a length of time for which the mobile device has not had the short-range communication link with the companion UE;
compare the length of time to a threshold; and
determine a cellular baseband operating mode based at least in part on the determination that the mobile device does not have the short-range wireless communication link with the companion UE and further based at least in part on said comparing the length of time for which the mobile device has not had the short-range communication link with the companion UE to the threshold.

14. The mobile device of claim 13 ,
wherein the cellular baseband operating mode is further determined based at least in part on a minimum functionality level associated with user settings, user activity or application activity at the mobile device.

15. The mobile device of claim 14 ,
