Abstract

A radiotelephone system comprised of a radiotelephone-pair suitably intercoupled theretogether to permit transfer of data, such as NAM information, therebetween. A first of the radiotelephone-pair comprises a radiotelephone of conventional construction. A second radiotelephone of the radiotelephone-pair comprises a radiotelephone having circuitry to transmit efficiently an information signal upon a cellular, communication system of increased capacity. The data sequence contained in the first radiotelephone is transferred to the second radiotelephone to permit a communication link to be formed between the second radiotelephone and a cellular, communication network.

Claims

1. A method of controlling a cellular radiotelephone including a controller, transceiver circuitry coupled to the controller to communicate with a fixed radio site, and a receptive coupler coupled to the controller to receive an external intercoupler, comprising the steps of:

communicating through the receptive coupler with a microprocessor associated with the external intercoupler to obtain a code of a data set;

establishing via the transceiver a communication link with the fixed radio site using the code while said receptive coupler receives said external intercoupler; and

precluding, by the controller, the establishment of a subscriber communication link with the fixed site using the code upon disconnection of the external intercoupler from the receptive coupler.

2. The method as defined in claim 1, wherein said step of communicating with the external device microprocessor includes communicating between the radiotelephone processor and the external device microprocessor to receive the code from the external device microprocessor.

3. A radiotelephone for communicating in a cellular radio system having at least one fixed radio site and a plurality of radio telephone units, the radiotelephone comprising:

a radio transceiver; and

a receptive coupler coupled to the radio transceiver for receiving an external intercoupler, said receptive coupler being adapted to communicate with a microprocessor associated with the external intercoupler to receive a code related to a data set and establishing a communication link with the fixed radio site via the radio transceiver using the code only while said receptive coupler receives said external intercoupler.

4. A radiotelephone according to claims 3, wherein the receptive coupler is adapted to receive a code related to user identification information uniquely associated with a user.

5. A radiotelephone according to claim 3, wherein the receptive coupler is adapted to receive a code related to a telephone number uniquely associated with the user.

6. A radiotelephone according to claim 3, wherein the receptive coupler is adapted to receive a code related to one of transmitting power, receiving sensitivity, repertory dialing numbers, or telephone functions.

7. A cellular radiotelephone system, comprising:

a portable device including a microprocessor to selectively access an identification code stored in the portable device and an external connector coupled to said microprocessor; and

a radiotelephone for communicating with at least one fixed radio site, said radio telephone comprising;

radio transceiver circuitry;

a radio connector to releasably receive said external connector; and

circuitry connected between said radio connector and said radio transceiver circuitry, said circuitry communicating said identification code between said microprocessor and said transceiver circuitry to effect a connection between said microprocessor and said radio transceiver circuitry, said radio transceiver circuitry selectively establishing a communication link with the fixed radio site using said identification code only while said radio connector receives said external connector, wherein the radiotelephone'"'"'s identification is taken from said portable device only while said portable device and said radiotelephone are interconnected.

8. The cellular radiotelephone system as defined in claim 7, wherein said circuitry includes a processor controlling operation of the radio transceiver circuitry and communicating with the external microprocessor through the connector.
