Abstract

Systems and methods for improving battery life and transmission efficiency of mobile devices are disclosed. Some embodiments provide for application and/or context aware fast dormancy on a mobile device or user equipment (UE) and/or via a proxy server. By incorporating application and context information, e.g., when an application opens a connection, what kind of applications are present, how the application normally behaves and whether the application is running in background or transmitting background data, embodiments provide for an improved and enhanced fast dormancy operation.

Claims

1. A method of radio state transition on a mobile device in a manner that is application aware in a mobile network, the method, comprising:

modifying a time at which a request to trigger transition of a radio state is to be sent, the request to be sent from the mobile device,

wherein, the transition of a radio state is a transition from a first resource state to a second, more resource efficient, state;

wherein, the time is modified based on an application accessed on or via the mobile device.

2. The method of claim 1, wherein, modifying the time includes determining whether the request will be sent based on current or past behavior of the application.

3. The method of claim 1, wherein, modifying the time reduces a delay between the request to trigger the transition and a previous data transmission of the application.

4. The method of claim 1, wherein, the request is sent to a radio network element in the mobile network;

wherein, the radio network element includes a radio access network (RAN).

5. The method of claim 1, wherein, the resource efficient state includes a lower power radio state or device battery efficient state.

6. The method of claim 1, wherein, the network includes any mobile network that is defined or covered in 3GPP.

7. The method of claim 1, wherein, the transition of the radio state includes the transition from a DCH state to a lower powered state.

8. The method of claim 1, wherein, the mobile network is a 3G network and the resource efficient state includes one or more of:

IDLE, CELL_PCH, URA_PCH or CELL_FACH.

9. The method of claim 1, wherein, the resource efficient state includes, IDLE_CCCH, IDLE_FACH, or PCH.

10. The method of claim 1, wherein, the mobile network is a 4G or LTE network and the resource efficient state includes an IDLE state.

11. The method of claim 1, wherein, the request is included in a signaling connection release indication (SCRI) request.

12. The method of claim 1, wherein, an amount the time is modified is determined on an application by application basis.

13. The method of claim 1, wherein an amount the time is modified is determined on how the application is behaving or has previously behaved.

14. The method of claim 1, wherein, an amount the time is modified is determined based on behavior of the application, wherein the behavior of the application includes information regarding whether data transmission for the application is complete or temporarily suspended.

15. The method of claim 14, wherein modifying a time at which a request is sent comprises delaying a time until the request is sent if the application is temporarily suspended.

16. The method of claim 14, wherein modifying a time at which a request is sent comprises delaying indefinitely a time until the request is sent if the application is temporarily suspended.

17. The method of claim 14 wherein modifying a time at which a request is sent comprises accelerating a time at which the request is sent if data transmission is complete.

18. The method of claim 14 wherein modifying a time at which a request is sent comprises sending the request immediately if data transmission is complete.

19. The method of claim 1, wherein, the radio state switching that is application aware is an enhancement or improvement of fast dormancy implementation by one or more of, a radio chip manufacturer, a device manufacturer, or mobile operators or carriers.

20. The method of claim 1, wherein, the radio state switching that is application aware is an enhancement or improvement of the 3GPP Release 8, Release 9, Release 10, or Release 11 or later fast dormancy implementation.

21. The method of claim 1, wherein, the radio state switching that is application aware is an enhancement or improvement of the 3GPP pre-Release 8 fast dormancy implementation.

22. A method for directing fast dormancy on a mobile device that is context aware, the method, comprising:

adjusting an initiation time for a radio release request message from the mobile device based on an indicia of contextual data detected at the mobile device.

23. The method of claim 22, wherein the indicia of contextual data comprises historical or statistical information gathered from a mobile application accessed via or on the mobile device.

24. The method of claim 22, wherein, a local proxy on the mobile device to adjust the initiation time of the radio release request message.

25. The method of claim 22, wherein monitoring a first indicia comprises determining whether an application on the mobile device has temporarily suspended or has completed a data transmission.

26. The method of claim 22, wherein monitoring a first indicia comprises monitoring a history of an application'"'"'s behavior, the application accessed via or on the mobile device.

27. The method of claim 22, further comprising determining an initiation criterion based on offline learning and wherein adjusting an initiation time is based at least in part on the determined initiation criterion.

28. The method of claim 22, further comprising determining an initiation criterion based on on-demand learning and wherein adjusting an initiation time is based at least in part on the determined initiation criterion.

29. The method of claim 28, wherein performing on-demand learning comprises adding rules to a rule set.
