Abstract: A vehicle locating system (200) includes a beacon (108) carried by a vehicle, a tracking control station (106) for generating a beacon activation signal (110) which enables the beacon (108) to broadcast a vehicle identification signal (112), and one or more mobile communication devices (116, 118) which include a first receiver (516) utilized to receive a location signal (122) identifying a geographic location of a mobile communication device, and a transceiver (406) utilized to provide communication between said mobile communication device and a communication system controller. The one or more mobile communication devices (116, 118) further include a second receiver (502) utilized to receive the vehicle identification signal (112) broadcast by the beacon (108), and a vehicle tracking controller (520), responsive to the vehicle identification signal (112) which is received, for controlling a transmission of the vehicle identification signal (112) and the location signal (122).

Abstract: A method for communication between a dispatch center (16) and a plurality of wireless communication devices (36) within a vehicle dispatch system (10). The method includes receiving a request for dispatch (28) including an assignment location (66). An assignment message (32) including a first criteria paremeter (62) and a location parameter (50) is sent to the plurality of wireless communication devices (36). Each wireless communication device (36) receives the assignment message (32) including the first criteria parameter (62) and the location parameter (50), compares the location parameter (50) with a current location (56) using the first criteria parameter (62), transmit a reply (38) to the dispatch center (16) in response to the detection of an affirmative match.
