Abstract
A method of transferring a user message-conveying radiotelephone call by a subscriber unit from a first radio coverage area, served by a first fixed control unit which is coupled to a wireline telephone switch, to a second radio coverage area served by a second fixed control unit, includes transmitting a directory number, associated with the first fixed control unit and the wireline telephone switch, the directory number identifying a wireline telephone number of the first fixed control unit, from the first fixed control unit to the subscriber unit; storing the transmitted directory number at the subscriber unit; transmitting the stored directory number from the subscriber unit to the second fixed control unit when a need for transfer of the radiotelephone call to the second fixed control unit from the first fixed control unit is determined; calling the transmitted directory number from the second fixed control unit; in response to the calling of the directory number, connecting the second fixed control unit to the first fixed control unit via the wireline telephone switch; and transferring control of the radiotelephone call from the first fixed control unit to the second fixed control unit by dialing the transmitted directory number from the second fixed control unit.
