Abstract
When a terminal enters a cell of a personal-use base station (NBTS) arranged in a certain location area, the terminal receives a location area identifier having a number that is different from an identifier of the location area, and transmits a location updating request with the reception of the location area identifier as a trigger. On receiving the location updating request, a VLR or an NRNC having a registration table, in which the ID of the personal-use base station and the ID of a terminal allowed to use the personal-use base station are registered, judges whether the terminal issued the location updating request is the terminal allowed to use the personal-use base station by referring to the registration table. If the terminal issued the location updating request corresponds to the terminal allowed to use the personal-use base station, the terminal is placed under a status where it is capable of performing communication in the cell, and if not, the terminal is placed under a status where it is incapable of performing communication in the cell.
