Abstract
An intelligent call forwarding system for routing incoming calls to at least one of a plurality of alternate communication devices when a called party cellular communication device installed in a vehicle is unavailable to directly receive the call. The system includes a plurality of cell sites disposed at predetermined geographical locations for providing cellular communication service to the called party cellular communication device. An active cell site that provides cellular communication service to the called party cellular communication device is stored in a memory device. Each cell site is related to at least one alternate communication device that is nearest in geographical location thereto. When an incoming call is received and the cellular communication device is “unavailable”, a cellular central office selects an alternate communication device that is mapped to the most recent active cell site stored in the memory device, and the incoming call is forwarded to the selected alternate communication device via a network. In a preferred embodiment the memory device stores a history of most recent active cell sites and determines the direction of travel of the vehic…
