Method for determining subscriber's home zone area for home zone service

摘要

PURPOSE: A method for determining a subscriber home zone region for home zone service is provided to enable to determine the subscriber home zone region effectively by allowing a subscriber to determine the subscriber home zone region freely. CONSTITUTION: A home zone region in which a subscriber want to register is temporarily indicated on a coordinate map(3a). Points(edges) of which horizontal boundary lines and vertical boundary lines in the temporary home zone region are crossed on the coordinate map each other are indicated(3b). Latitudes and longitudes for the above crossing points are measured by GPS receiver(3c). A latitude and longitude for a bin which includes each crossing point is determined by a latitude and longitude of the corresponding crossing point(3d). By making definite straight lines for linking between bins which a latitude and longitude have been determined, a closed curved surface is formed, where the entire inside of this closed curved surface becomes the home zone region of the corresponding subscriber(3e). All bins in the above closed curved surface are selected(3f). A home zone region is determined by synthesizing the information for sector lists of the above selected bins(3g).
