PROBLEM TO BE SOLVED: To obtain detailed service information of a region in a narrower area by receiving a paging calling signal and a GPS signal, measuring and discriminating its own position, and extracting message information for its own. SOLUTION: A pager terminal 3 receives a paging calling signal 230 and identifies it as a calling for its own when comparison identification information (comparison ID) of its own satisfies identification conditions stipulated by a calling ID. The calling ID includes an area ID. The paging terminal 3 receives a GPS signal 500 from a GPS satellite, determines its own position and stores determination information in a RAM 302. The RAM 302 stores the determination information of the present (the current time) and the last time (two minutes ago, for example). A CPU 301 calculates a motion speed and direction of its own therefrom. Thus, before the self's entering a specified area, information on the received a paging calling signal by specifying the area can be extracted after entrance. |
