MOBILE TERMINAL LOCATION RETRIEVAL METHOD, ITS SYSTEM, METHOD FOR CONFIRMING LOCATION OF SPECIFIC PARTY AND SIMPLE MOBILE TERMINAL EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To specify a location of a mobile terminal equipment within a very limited range by eliminating the need for calling the mobile terminal equipment and reducing the line occupancy time. SOLUTION: For example, when a prescribed position retrieval request including a telephone number of a mobile terminal equipment 104 is given from a terminal equipment 101 to a service control node 100, a prescribed area is roughly confirmed by position registration information of the terminal equipment 104 by the node 100, the terminal equipment 104 is verified on a PHS network by a verification request from each base station 102 in the area to the terminal equipment 104, and an interface number with the base station 102 near the terminal equipment 104 obtained in this case is converted into area name data by the node 100 and the data are sent to a request source terminal equipment 101.
