PROBLEM TO BE SOLVED: To surely perform communication with a central equipment through a mobile station and a base station by digitally converting a reception input voltage level from the mobile station received in the base station in an A/ D conversion part. SOLUTION: This system is composed of the plural base stations 102-1 and 102-2, the central equipment 103 for remotely operating the base stations and the mobile station 101. In the base stations 102-1 and 102-2, a radio part performs radio wave propagation with the mobile station 102 and a reception input voltage detection part detects a radio wave level from the mobile station 102. Then, the detected radio wave level is A/D converted and turned to digital signals in the A/D conversion part and the respective kinds of signals for monitoring and controlling the base stations and the signals required for the communication with the mobile station 101 are information-transmitted to the central equipment 103 in a digital transmission part. Further, radio is controlled in a control part. The central equipment 103 receives the voltage levels from the base stations in the digital transmission part, compares and judges them by an inter-base-station reception input judgment part and controls the respective base stations in a base station control part. |
