Abstract

Example methods and apparatus to conditionally invoke network recovery are disclosed. A disclosed example method in a wireless device involves detecting a radio resource connection failure and identifying whether downlink data is expected. The disclosed example method also includes initiating a registration procedure when downlink data is expected.

Claims

1. A method in a wireless device, comprising:

detecting a radio connection failure;

identifying whether downlink data is expected; and

initiating a registration procedure when downlink data is expected.

2. A method as described in claim 1, further comprising initiating the registration procedure when the wireless device has uplink user data pending.

3. A method as described in claim 1, wherein the wireless device identifies whether downlink data is expected after determining that no uplink user data is pending.

4. A method as described in claim 1, further comprising preventing the registration procedure when no downlink data is expected.

5. A method as described in claim 1, wherein the wireless device identifies whether downlink data is expected based on information provided by an application layer.

6. A method as described in claim 5, wherein the application layer receives the information from at least one of an e-mail application, a video telephony application, a file transfer protocol application, a browser application, or a navigation application.

7. A method as described in claim 1, wherein the wireless device identifies whether downlink data is expected based on information provided by at least one of a radio link control, RLC, layer or a medium access control, MAC, layer.

16. A method as described in claim 3, further comprising the wireless device receiving an indication of downlink data expected from a lower layer.

17. A method as described in claim 16, wherein the lower layer is lower than a layer associated with a non-access stratum.

20. A method as described in claim 1, wherein the radio connection failure comprises a release cause of radio resource control, RRC, connection failure.

21. A method as described in claim 20, further comprising initiating an RRC connection re-establishment procedure when a medium access control, MAC, layer of the wireless device is not in discontinuous reception, DRX, mode.

22. A method as described in claim 20, further comprising initiating an RRC connection re-establishment procedure when a radio link control buffer for any data bearer is not empty.

26. A method as described in claim 3, further comprising the wireless device receiving an indication of downlink data expected from an application layer.

8. A mobile station including hardware and software stored on a tangible computer readable medium that, during operation, cause the mobile station to, at least:

detect a radio connection failure;

identify whether downlink data is expected; and

initiate a registration procedure when downlink data is expected.

9. A mobile station as described in claim 8, wherein the registration procedure comprises at least one of tracking area updating procedure or a routing area updating procedure.

10. A mobile station as described in claim 8, wherein the hardware and software further cause the mobile station to initiate the registration procedure when the wireless device has uplink user data pending.

11. A mobile station as described in claim 8, wherein the hardware and software further cause the mobile station to identify whether downlink data is expected after determining that no uplink user data is pending.

12. A mobile station as described in claim 8, wherein the hardware and software further cause the mobile station to prevent the registration procedure when no downlink data is expected.

13. A mobile station as described in claim 8, wherein the mobile station is adapted to identify whether downlink data is expected based on information received from an application layer.

14. A mobile station as described in claim 13, wherein the application layer receives the information from at least one of an e-mail application, a video telephony application, a file transfer protocol application, a browser application, or a navigation application.

15. A mobile station as described in claim 8, wherein the mobile station identifies whether downlink data is expected based on information provided by at least one of a radio link control, RLC, layer or a medium access control, MAC, layer.

18. A mobile station as described in claim 11, further comprising the mobile station receiving an indication of downlink data expected from a lower layer.

19. A mobile station as described in claim 18, wherein the lower layer is lower than a layer associated with a non-access stratum.

23. A mobile station as described in claim 8, wherein the radio connection failure comprises a release cause of radio resource control, RRC, connection failure.

24. A mobile station as described in claim 23, further comprising initiating an RRC connection re-establishment procedure when a medium access control, MAC, layer of the wireless device is not in discontinuous reception, DRX, mode.

25. A mobile station as described in claim 23, further comprising initiating an RRC connection re-establishment procedure when a radio link control buffer for any data bearer is not empty.

27. A mobile station as described in claim 11, further comprising further comprising the mobile station receiving an indication of downlink data expected from an application layer.
