The present invention provides a method and apparatus that enables handover of a mobile station between a cellular network and a wireless network without control intervention from the cellular network and independent of employed air interface technology. The signaling and control of a switch, for example SS7 messaging, is not required to achieve the handovers implemented by the present invention. In particular, a call is connected (508) between a mobile station (202) and a remote station (204) through a media gateway (210). The media gateway is connected to the mobile station via a first connection line and to the remote station via a second connection line. When the mobile station has entered (514, 516) a transition area (302), a third connection line is established (518) between the media gateway and the mobile station. Communication between the media gateway and the mobile station then is handed-over (526, 528) from the first connection line to the third connection line and, thereafter, the first connection line is disconnected (530).
