An anchor RS acts as the single interface between the switched telephone network and the wireless communications system throughout an entire call, even if the subscriber unit travels to different radio systems during the call. This allows (1) the signaling to set up the connections between the anchor and target RPCUs; and (2) the maintenance information for the call to remain in the anchor RPCU, which is connected to the original switch. This avoids tying up network switches with exchanging signals and call maintenance information about service features, thus resulting in a substantial "savings" in valuable telephone network resources. Also, existing switches do not need to be replaced or reconfigured to accommodate this hand over method.

[ We claim:] [1.] A method for handing over a wireless communication from a current serving radio system to a target radio system, wherein the current serving radio system is directly connected to an anchor radio system which connects the wireless communication to a wireline telephone network, the method comprising the steps of:a. determining that the wireless communication is to be handed over from the current serving radio system to the target radio system;b. establishing an inter-radio system interface between the anchor radio system and the target radio system;c. handing over the wireless communication from the current serving radio system to the target radio system in a manner so that the anchor radio system remains connected to the wireline telephone network and the target radio system is bridged with the anchor radio system with no intervening radio systems.
