  • Publication number: 20110053588
    Abstract: A method for implementing call re-establishment using a user equipment (UE) configured to communicate with a wireless communication network includes detecting at least one of a radio link failure and a protocol failure of a connection between the UE and a serving cell. A target cell of the wireless communication network is selected and a received signal level for the target cell is compared to a signal level threshold. When the received signal level for the target cell exceeds the signal level threshold, call re-establishment is initiated on the target cell. The signal level threshold may be encoded within a system information type 21bis message, or a system information element. In some cases, the signal level threshold is equal to a minimum signal level required on the target cell.
