An apparatus provided with a control table (30) for storing a plurality of MINs and counted values as certification parameters corresponding to the respective MINs in order to prevent fraudulent use by executing the certification before connection with a base station. When registering an MIN, it is examined whether or not the inputted MIN has been already registered in the control table (30). If already registered, the input is interpreted as a registration, and the MIN and the counted value already registered are held as they are. On the other hand, if not, it is further examined whether or not any MIN whose counted value is "0" has been registered in the control table (30). If any, the inputted MIN is registered. If not, the inputted MIN and the initial value "0" of the counted value are registered in the empty area of the control table (30). <IMAGE> |
