PCT No. PCT/AT90/00025 Sec. 371 Date Nov. 6, 1991 Sec. 102(e) Date Nov. 6, 1991 PCT Filed Apr. 4, 1990 PCT Pub. No. WO90/12469 PCT Pub. Date Oct. 18, 1990.Base stations (FSn) of cordless telephones are connected via subscriber lines (TL) to a private automatic branch exchange (PABX). There are fewer base stations (FSn) than mobile sets (MT) and from each base station (FSn), a connection can be set up to any mobile set (MT). The change of a mobile set (MT) into the radio cell (FBn) of another base station (FSn) is updated via the call-forwarding and follow-me facilities of the private automatic branching exchange (PABX). For this active subscriber administration by the private automatic branch exchange (PABX), the individual identifications of the mobile sets (MT) are exchanged with the respective base stations (FSn) even if no calls are being made. As a result, a cordless subscriber can be reached, especially in the case of wide-area private automatic branch exchanges (PABX), even if he is moving out of the radio cell (FBn) of one base station (FSn) and changes into the radio cell (FBn) of another one. The base stations (FSn) form a microcellular system.
