Abstract

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.

2. Description of the Related Art Conventionally, in a base station selection method in a mobile radio communication system, a base station which has received a transmission signal from a mobile station converts the received input into a digital signal and converts the data into a parent system which controls the system. The base station selected the base station with the highest reception input based on this data. However, since the base station is selected based on the reception input from the mobile station to the base station, there is a risk that the base station whose reception input is high instantaneously may be selected, and the mobile station is located. There is a drawback that an optimum base station cannot always be selected for a position.

The above-mentioned conventional system is a system in which a base station is selected based on a reception input of the base station. However, since the other party is a mobile station, communication is performed during movement. In this case, the reception input of the base station often fluctuates instantaneously due to fading or the like, and the reception input data at the time of detection of the reception input happens to be high because the reception input data at the time of detection of the reception input is used as a reference for selecting the base station. There is a risk that a base station is selected, and there is a problem that an optimum base station cannot always be selected for the position of a mobile station.
