ABSTRACT:
The present invention provides a system and method for reconnecting a dropped mobile telephone call without input from the dropped party or the remaining party. In accordance with the present invention, the system determines that a call has been terminated abnormally, possibly due to an unsuccessful transition between cell towers. The system then initiates reconnection of the dropped party with the remaining party with no input from either party. The remaining party may optionally hear a recorded message while the call is reconnected.
