摘要

PROBLEM TO BE SOLVED: To provide a position specifying system where terminal equipment are facilitated small and light at a low cost. SOLUTION: In a PHS network, position information management equipment 4 that manages a current position of PHS terminal equipment 3 and a connector 1 to which plural base stations A, B, C,... are connected are connected to an exchange 2, the PHS terminal equipment 3 recognizes that the PHS terminal equipment 3 belongs to either of service areas where a radio wave reaches from each base station to store the result as base station identification information, when the service area is changed due to movement, the base station identification information is rewritten and is informed to the position information management equipment 4 to register the position automatically. In this case, a coordinate location information database 10 storing coordinate location information and a map information database 11 storing map information are connected to control retrieval processing, a retrieval processing unit 9 is connected to the exchange 2 and the PHS terminal equipment 3 receives and outputs the map information from the base station identification information to allow a person to recognize the current position.
