Method of an apparatus for sensing the unauthorized movement of vehicles and the like and generating an alarm or warning of vehicle theft

A novel method of and system for enabling the use of one portable cellular phone only, in voice communication with a cellular network control center for voice-requesting position or location data services, and, with the aid of a vehicle GPS-transponder activated in response to signaling from the control center over cellular network channel control paths, to receive and process at the vehicle GPS location data from satellites, and to transmit the data over the said channel control paths to the control center, for then sending therefrom to the user of the portable cellular phone.

Methods of and system for portable cellular phone voice communication and positional location data communication using the cellular phone network control channel

A novel method of and system for enabling the use of one portable cellular phone only in voice communication over a radio voice channel with a cellular network control center for voice-requesting position or location data or other services; and, with the aid of a vehicle GPS-transpoder activated in response to signaling from the control center over a separate radio-data channel path, to receive and process at the vehicle GPS location,data from satellites, and to transmit the location data over the said data control path to the control center; and for then sending such data and information therefrom to the user of the portable cellular phone&#x2014;the system being also adaptable for use by dispatcher managers of fleets of vehicles.
