PROBLEM TO BE SOLVED: To always select an optimum base station with respect to the position of a mobile station by compare-detecting positional information of the mobile station and communication area information of each base station stored in advance so as to select the optimum base station. SOLUTION: In the case of calling the mobile station from a control office, e.g. at the time of dialing for calling the mobile station 9 from a telephone equipment 2 within the control station, signals for calling the mobile station are successively sent from base stations 8 by way of an exchange 3, etc. At time of judging that the call signal is for its own station, the mobile station 9 converts positional information of GPS part 10 to a prescribed format by a conversion part 11. A line controller 5 receiving this signal through the base station 8 and a repeater controller 7 selects the optimum base station by an each base station communication range information memory and a mobile station position compare-detecting part 6 within the equipment, sends back a response to the telephone equipment within the control station, execute the selection of the optimum base station 8 and line constitution and allow the optimum base station 8 to send a call signal to the mobile station 9. |
