ABSTRACT:
A mobile telephone system includes: a portable telephone set, an adaptor on a vehicle for the portable telephone set to rest thereon, a remote controller unit for dialing and voice talking, and a transceiver unit for modulating/demodulating voice signal and control signals, and transmitting/receiving radio frequency signals. The portable telephone set has apparatus for electrically connecting to the adaptor when the portable telephone set is rested thereon, and a first control circuit for transferring identification numbers of the portable telephone set to the transceiver unit and then disabling a predetermined part of functions of the portable telephone set except charging a battery of the portable telephone set from the adaptor. The transceiver unit has a second control circuit for storing the identification numbers transferred from the portable telephone set, and allowing the transceiver unit and the control unit to operate as a vehicle telephone system using the identification number of the portable telephone set. The adaptor electrically connects between the portable telephone set, the remote control unit and the transceiver unit. The second control circuit may store second identification numbers so that the transceiver unit and the control unit may operate as an independent vehicle telephone system or as a multiple telephone number system.
