Abstract:
1. A method of voice and GPS satellite constellation positional location data radio communication over a cellular phone network having a cellular network radio voice-communication path and a cellular network different data communications radio control channel path normally used to set up phone calls, break down phone calls and switch cell sites, each separately communicating along their respective different paths with a network operations control center, that comprises, user initial voice-calling of the control center from a portable cellular telephone location and over the cellular network radio voice-communication path requesting user-location information services of the control center; upon user verification, sending a radio wake-up signal from the control center over the cellular network data-communication radio control channel path to be received at said location, providing a radio transponder and a GPS receiver adapted to receive GPS satellite constellation location data transmission frequency and a microprocessor module at said user location; activating the GPS receiver in response to receipt of said wake-up radio signal sent from the cellular network control center over its data-communication radio control channel path, to receive and microprocessor-process the location data received by the GPS receiver from the GPS satellite constellation at the user location and thereupon to activate the transponder at said user location to transmit the microprocessor-processed received location data over the cellular network data-communication radio control channel path back to said control center, associating at the control center, the transmitted user-location data received over the cellular network data-communication radio control channel path by the control center with the initial user voice call request received along the cellular network radio voice-communication path at the control center, and sending the requested user-location services information from the control center to the user.
