METHODS AND APPARATUS TO INVOKE DATA EXCHANGE BASED NETWORK RECOVERY
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.
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.
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.
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.
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.
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.
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.
26 . A method as described in claim 3 , further comprising the wireless device receiving an indication of downlink data expected from an application layer.
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.
