Abstract
A system and method for recovering from a lost connection between a mobile station and a mobile communications system after a traffic channel has been successfully assigned are provided. After the connection is lost, rather than dropping the call altogether, the party on the other end of the call is connected to an announcement. While the announcement is playing, the system pages the mobile station in an effort to re-locate it and re-establish a traffic channel. When a traffic channel is successfully re-established, the call is connected. The connection may be lost during handoff, conversation (normal use), mobile termination or mobile origination for example.
