ABSTRACT:
A system for confirming a position of a moving terminal in a radio communication network including a plurality of base stations each corresponding to one of a plurality of individual radio areas. A moving terminal having a specific identification number is provided which includes a receiver for receiving a paging signal including the specific identification number, and a transmitter for wirelessly outputting a response signal in response to the paging signal. A first data base is provided for storing position data representing positions within the plurality of individual radio areas to which a person holding the moving terminal may visit, and base station data representing respective ones of the base stations corresponding to the positions to which the person holding the moving terminal may visit. The position data and the base station data are stored in the first data base in an associated manner with respect to the identification number of the moving terminal. A position retrieving means is provided for identifying base station data corresponding to a given one of the base stations which receives the response signal output by the moving terminal, for retrieving from the first data base corresponding position data associated with the identified base station data, and for outputting the retrieved position data as a candidate for location of the person holding the moving terminal.
