ABSTRACT:
An object of the invention is to make improvement in the configuration of location registration areas. When a base station13P is newly installed in a location registration area30A, the base station13P recognizes a location of its own with GPS or the like and performs communication with a plurality of surrounding base stations13Q to select a location registration area30A to which it should belong, based on the belonging status of the surrounding base stations13Q and the location of its own. If the base station13P is located near a boundary between location registration areas and if the surrounding base stations13Q belong to a plurality of location registration areas, the location registration area to which the base station13P should belong may be selected so as to average traffics in the respective location registration areas, or the location registration area with the smallest number of base stations belonging thereto may be selected so as to average the numbers of base stations in the respective location registration areas. The base station13P broadcasts an area identifier of its belonging location registration area30A to mobile stations under control thereof and starts provision of service thereto.
