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.

Claims

1. A mobile telephone system comprising:

a portable telephone set capable of operating outside a vehicle, including;

a keyboard;

a microphone;

an earphone;

a battery;

a first memory for storing identification numbers registered to said portable telephone set;

a first transceiver circuit including a transmitter circuit and a receiver circuit, said first transceiver circuit receiving and transmitting a radio frequency wave carrying voice signals and the identification numbers;

a first control circuit, coupled to said first memory, for controlling placing/answering of a call according to the identification numbers stored in said first memory; and

a first electrical connection means;

a transceiver unit, including;

a second transceiver circuit for outputting a radio frequency signal carrying a voice signal and the identification numbers of said portable telephone set when the identification numbers are transferred to said second transceiver circuit;

a second memory for storing the identification numbers;

a second control circuit, coupled to said second memory and said second transceiver circuit, for transferring the identification numbers to said second transceiver circuit and for controlling placing/answering of a call according to the identification numbers sorted in said second memory; and

adaptor means, comprising;

second electrical connection means for connecting to said first electrical connection means, and for outputting an adaptor signal, said first control circuit transferring the identification numbers stored in said first memory to said second memory on receiving the adaptor signal; and

wirings to connect to said transceiver unit,

said portable telephone set further including means for disabling a power supply to said first control circuit after the identification numbers stored in said first memory are transferred to said second memory.

2. A mobile telephone system as recited in claim 1, wherein said adaptor means further comprises a circuit for supplying a voltage to said portable telephone set so as to charge said battery.

3. A mobile telephone system as recited in claim 1, wherein said first electrical connection means is formed of socket means.

4. A mobile telephone system as recited in claim 3, wherein said adaptor means comprises cables and a jack provided on an end thereof to be detachable connected to said socket means.

5. A mobile telephone system as recited in claim 1, wherein said adaptor means further comprises means for supporting said portable telephone set.

6. A mobile telephone system comprising:

a portable telephone set capable of operating outside a vehicle, and portable telephone set including;

a first memory for storing identification numbers corresponding to said portable telephone set; and

a first control circuit, coupled to said first memory, for controlling placing/answering of a call according to the identification numbers;

a transceiver unit, including;

a transceiver circuit for outputting a radio frequency signal carrying a voice signal and the identification numbers;

a second memory; and

a second control circuit, coupled to said second memory and said transceiver circuit, for controlling placing/answering of a call;

an adaptor for electrically connecting said portable telephone set to said transceiver unit, and for outputting an adaptor signal which caused the first control circuit to transfer the identification numbers stored in said first memory to said second memory,

said portable telephone set further including means for disabling power supply to said first control circuit after the identification numbers stored in said first memory are transferred to said second memory.

7. A mobile telephone system comprising:

a portable telephone set capable of operating outside a vehicle, including;

a keyboard;

a microphone;

an earphone;

a battery;
