Methods and apparatus for mobile device recovery following radio link failure

摘要

Methods and apparatus to audibly provide messages in a mobile device at described. An example method includes detecting a radio link failure condition, in response to detecting the radio link failure condition, sending a cell update message to a medium access control of the user equipment, detecting that a timer associated with a radio access bearer has expired before receiving confirmation from the medium access control of transmission of the cell update message to a network, and in response to detecting that the timer associated with the radio access bearer has expired and sending the cell update message to the medium access control, maintaining the radio access bearer associated with the timer.
