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.

Abstract: A radiotelephone system is comprised of a fixed site (120, Fig. 1) and a radiotelephone-pair (420) suitably intercoupled (436, 440, 444) theretogether to permit transfer of data, such as number assignment module (NAM) information, therebetween. A first (426 or 432) of the radiotelephone-pair comprises a radiotelephone of conventional construction using conventional band width. A second radiotelephone (432 or 426) of the radiotelephone-pair comprises a radiotelephone having circuitry to transmit more efficiently an information signal upon a cellular, communication system of increased capacity. The data sequence contained in a first radiotelephone of the pair is transferred to a second radiotelephone of the pair to permit a communication link to be formed between the second radiotelephone and a cellular, communication network. Thus a portable (426) may be used independently at off-peak-times, and intercoupled with a mobile (432) at peak times to make use of increased capacity but using the same NAM information as the portable. Only one NAM is thus required giving increased capacity at minimal cost.
