ABSTRACT:
Calls (ar) directed to wireless communication terminal equipment (KE) wirelessly connected to base stations (BS-H) of a home area (H) and to a communication network (KN) are switched to the appertaining base station (BS-H) in the home area (H) using the communication network (KN). The availability of the called wireless communication terminal equipment (KE) is determined using the base station. Given non-availability of the called wireless communication terminal equipment (KE), the calls (ar) are rerouted to the communication network (KN) using the performance feature of “call deflection” provided in the base station (BS-H) in the home area (H). The method can be integrated into existing communication networks (KN) with minimal outlay.
