PURPOSE:To increase the effect of usage for control lines, by detecting the position of mobile station in the base station unit and limiting the callout range to the minimum position of base station when the mobile station is called out from the control station. CONSTITUTION:A plurality of base stations 102 accomodating a plurality of radio lines are connected to the control station 101, the vacancy of the radio line corresponding to each base station 102 is detected with the control circuit of the base station number signal delivery control section 105, and the vacant line number signal and the signal of the base specific number are transmitted to the mobile station 109 of the base station zone 108 in the base station 102 via the transmission line 103 and relay line 104 from the base station numbering signal generation section 106 through the selection of the contacts t11-t1n. Next, the mobile station 109 in the zone 108 receives the vacant line signal in the base station 102 and the signal of the base station specific number, activates the control circuit of the mobile station 109, and the start signal and position memory signal are returned via the vacant lines. The control station 101 receives the start signal, position memory signal and position signal from the mobile station, connects the radio lines to the incoming circuit line 112, stores it to the position detection memory section 111 and the storage is informed to the mobile station 109. |
