Abstract
A cellular radio system is to be implemented in an existing facility which performs switching functions and provides service features, without requiring major changes therein. Communication between the individual base stations (BS,BS,BS,BS,) takes place by means of radio via existing radio channels. A cordless terminal (HS,) is assigned to a base station. If the terminal is located in the area of another base station during an incoming call, the terminal is searched for via a radio channel between the base stations. If it is found in the area of the other base station, the call is handed over to this other base station. The same applies to outgoing calls and to other functions.
