PROBLEM TO BE SOLVED: To obtain a mobile station location detecting system in which an inexpensive and small mobile station is used to detect the location of the mobile station. SOLUTION: The mobile station location detecting system is provided with the mobile station 1 for transmitting the mobile station ID of its own station, a plurality of base stations 2 for receiving the mobile station ID, measuring the electric field intensity of a received wave and the directivity of the received wave, and transmitting the measured information together with the received mobile station ID to a public network 3, and a location information center 4 connected to the public network 3 to calculate the location of the mobile station 1 corresponding to the received mobile station ID on the basis of the electric field intensity of the received wave from each base station 2 and the directivity of the received wave. By only the transmission of the mobile station ID of its own station by the mobile station 1, the plurality of base stations 2 measure various information required for calculating the location of the mobile station 1 and transmit the measured information to the location information center 4, and thus the inexpensive and small mobile station 1 is used to detect the location of the mobile station 1.
