PCT No. PCT/EP95/04661 Sec. 371 Date Sep. 23, 1996 Sec. 102(e) Date Sep. 23, 1996 PCT Filed Nov. 27, 1995 PCT Pub. No. WO96/17483 PCT Pub. Date Jun. 6, 1996To implement a radio system (PRS) for a closed user group by simple means and at low cost, a device (MONE) is proposed which connects at least one commercially available base station (BTS1, BTS2) to a telecommunication network (PSTN) via standard interfaces (PCM30, Abis). The device comprises a subscriber data base (ID) and means (MM) for checking whether a transmitted subscriber identification (IMSI) authorizes a subscriber to access the radio system (PRS). The device further controls the establishment and release of calls (CC) and performs radio resource management functions (RR). A radiotelephone (MS) authorized to access the radio system (PRS) is connected to the nearest base station (BTS1) at least for the duration of the call. |
