ABSTRACT:
It is an object of the present invention to realize a PHS terminal disabling system which can improve the recovery rate of lent PHS terminals. The PHS terminal disabling system includes a PHS terminal, a plurality of cell sites for communicating with the PHS terminal, and an exchange for performing an exchanging operation of the PHS terminal via the cell sites. The PHS terminal disabling system further includes a data base for holding, as management data for the PHS terminal, position information representative of a position of the PHS terminal and available area information representative of an area within which the use of the PHS terminal is permitted, and a main control apparatus connected to the exchange and the data base for updating the position information of the PHS terminal with a current position of the PHS terminal represented by data received from any cell site via the exchange and for causing, when the position of the PHS terminal is not included in the area represented by the available area information, the exchange to perform no exchanging operation.
