Abstract: PROBLEM TO BE SOLVED: To provide a proximity detecting method among mobile terminals that is effective from the viewpoint of signal traffics.
SOLUTION: A searcher side apparatus 310 transmits data with addition of information of all of the other mobile terminals as the approach detecting object in response to a location information service request to the particular mobile terminal as the location detecting object. When an exchange 306 acquires information of all of the other mobile terminals as the approach detecting object in addition to the particular mobile terminal as the location searching object, it determines whether all of the other mobile terminals as the approach detecting object in addition to the particular mobile terminal as the location searching object are within the service area or not. In the case where all mobile terminals as the approach detecting object are within the service area, respective location determining requests for all of the other mobile terminals as the approach detecting object are transmitted in addition to that of the particular mobile terminal as the location searching object. When a radio apparatus 304 acquires the location determining request, it executes location measurement in cooperation with a plurality of mobile terminals and transmits the result of location measurement. An exchange 306 acquires location information of all of the mobile terminals as the approach detecting object from the result of location measurement received and transmits a response to the searcher side apparatus 310 through a location information management apparatus 308.
