Abstract: A system and method for performing call handoff in a mobile communication system. The system is employed on commercial aircraft and enables calls to be transferred between different traffic service channels in order to continue and/or improve communications. In a conservation handoff scenario, user service channels are transferred between partially utilized traffic service channels resulting in unused traffic service channels that are released, thus freeing more traffic service channels for use by other aircraft. In a seizure handoff scenario, signal quality on one traffic service channel has begun to deteriorate prompting a call handoff wherein a call on the deteriorating traffic service channel is transferred to an unused user service channel on another traffic service channel already in use aboard the aircraft, thus allowing users to continue their calls.

Abstract: A system and method for performing call handoff in a mobile communication system. The system is employed on commercial aircraft and enables cans to be transferred between different traffic service channels in order to continue and/or improve communications. In a conservation handoff scenario, user service channels are transferred between partially utilied traffic service channels resulting in unused traffic service channels that are released, thus freeing more traffic service channels for use by other aircraft. In a seizure handoff scenario, signal quality on one traffic service channel has begun to deteriorate prompting a call handoff wherein a call on the deteriorating traffic service channel is transferred to an unused user service channel on another traffic service channel already in use aboard the aircraft, thus allowing users to continue their calls.
