Abstract:
1. A terminal status control system comprising: a registration table in which information concerning a terminal that is allowed to use a specific base station is registered; a judging unit judging whether a terminal that has entered a cell of the specific base station is the terminal registered in the registration table by referring to the registration table; and a control unit, if the terminal is the registered terminal, placing the terminal under a communicable status using the specific base station, and if not, placing the terminal under an incommunicable status using the specific base station, wherein the terminal is constructed so as to transmit a location updating request when system broadcast information containing a location area identifier received from a base station is changed due to an inter-cell movement, and the terminal status control system further comprises: a giving unit giving the specific base station the system broadcast information containing a location area identifier for the specific base station that is different from location area identifiers broadcasted in cells adjacent to the cell of the specific base station as a location area identifier that the specific base station broadcasts in the cell thereof, and wherein the giving unit is provided in a base station control apparatus that manages and controls the specific base station, the base station control apparatus includes a conversion unit converting a location area identifier of a location area, to which the specific base station belongs, the location area identifier being received from a location management apparatus managing the location of each terminal existing in the location area, into a unique location area identifier for the specific base station to make the system broadcast information containing the unique location area identifier, wherein the base station control apparatus includes a conversion table for the conversion unit converting the location area identifier managed by the location management apparatus into the unique location area identifier of the specific base station, and the giving unit gives the broadcast information containing the unique location area identifier converted by the conversion unit to the specific base station; and wherein the conversion unit converts the unique location area identifier for the specific base station contained in the location updating request from the terminal, which the base station control apparatus receives the location updating request from the specific base station, into the original location area identifier of the location area by use of the conversion table, in order to transmit the location updating request containing the original location area identifier to the location management apparatus.
