Abstract
Abstract A telecommunications system and method is disclosed for instructing a device interfaced with a vehicle's electrical system to activate or deactivate specific electrical devices, using the cellular network. This can be accomplished utilizing a mobile terminal or a unit containing the equivalency of a mobile terminal receiver, hereinafter referred to as a "Radio Interface Unit" (RIU), which is interconnected to a "Power Interface Unit" (PIU). The PIU directly interconnects to the vehicle's electrical system and ignition. The subscriber can then access their vehicle's electrical system from anywhere world-wide which reaches the mobile terminal by dialing their cellular phone number or a number associated with the RIU from another wireless or wireline phone. The RIU would then "answer" the call and receive instructions from the subscriber to activate or deactivate electrical devices on the vehicle.
