てしまう恐れがある。When the position of a mobile station is to be specified in a conventional mobile communication system, it can only be specified until the mobile station is within the service area of a wireless base station whose position is registered. . It is very difficult to specify the position of a position search using the received electric field level without performing calculations in consideration of the terrain, fading at the time of reception, and the like. For position detection using a mobile station with a GPS device, a GPS device must always be provided. Therefore, an on-vehicle type mobile station requires a GPS device for each vehicle, which increases device costs. Further, in a portable type mobile station, the size of the mobile station is increased, so that there is a possibility that the function of the original portable type may be impaired.
