Abstract
A cellular communications device for communicating over a cellular network control channel of a cellular mobile radiotelephone (CMR) system. A transmitter can transmit a data message formatted to correspond to an identification signal transmitted by a cellular radiotelephone when that device identifies itself to the CMR system. The data message contains selected data and is transmitted via the reverse overhead control channel of the cellular network control channel. A receiver can receive command signals from a mobile switching center of the CMR system via a forward overhead control channel (FOCC) of the cellular network control channel. A controller controls operation conducted by the transmitter and the receiver.
