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.

Abstract: Handoff between coverage areas is achieved in a radiotelephone system coupled to standard wireline switches. Upon initiation of a radiotelephone call in one radio coverage area, a directory number and radio call identifier (203) are downloaded to the subscriber unit (101) from a fixed control unit (111) associated with the coverage area. When the subscriber unit determines a handoff to a target radio coverage area is desirable, it transmits the directory number and radio call identifier to another fixed control unit (113) associated with the target radio coverage area. This fixed control unit calls the directory number and is coupled to the first fixed control unit via the standard wireline switch (115, 117). The radio call identifier is then sent to the first fixed control unit to enable the proper connection for handoff.
