In a mobile communication system including a plurality of base stations 10 and an MS position administrating station 30 connected to each of the base stations via a communication network, at least one of the base stations detects an arrival angle of a position detection signal from a mobile station and an average received power or propagation distance, and transmits the detected values as position detection parameters to the MS position administrating station, and the MS position administrating station detects the position of the mobile station on the basis of the position detection parameters and map information of an area including the base station.
