Abstract
A method and system for reconnecting dropped calls in a mobile telecommunications network. Upon detecting a call drop of an ongoing call, a mobile station involved in the call transmits a call reconnect request to a target cell in the network. The target cell can be selected from a neighboring cell list received from a serving cell during the call. In response to the call reconnect request, a target switching node associated with the target cell locates the call and reconnects the mobile station to the call using a traffic channel in the target cell.
