A terminal usage limiting apparatus for limiting the use of a portable telephone in a specific predetermined area. The terminal usage limiting apparatusis installed to provide service to mobile terminalsin a usage limiting areaThe terminal usage limiting apparatusoutputs control signals as a base station and additional usage limit messages. The terminal usage limiting apparatusenables a mobile terminalin the usage limiting areato recognize the apparatusas a base station so that the mobile terminal is switched from the base station to the apparatusAs a result, the mobile terminalreceives a usage limit message from the apparatusThus, the mobile terminalenters into a predetermined operation limit mode where call originations are restricted. In addition, in this mode, the mobile terminalreceives control messages from the terminal usage limiting apparatus, and the control message includes a long code mask corresponding to the apparatusBecause of the unique long code mask, the mobile terminalis also limited in receiving calls from the base stationsandvia the paging channel.
