ABSTRACT:
When moving from a public wireless area to a local wireless area, a mobile communication terminal transmits its telephone number to a local wireless service authentication server to inquire whether the mobile communication terminal can receive a local wireless service. The local wireless service authentication server, in response to the inquiry, determines whether the telephone number of the mobile communication terminal itself is registered in a local telephone number storage unit. When the number is registered therein, a transmission power level reduction instruction signal is transmitted to the mobile communication terminal. The mobile communication terminal, in response to the reception of the signal, controls the wireless unit to reduce output level of the transmission power in a wireless unit to a level that it can be received by a local base station while it cannot be received by a public base station. This enables restricting communication that uses public wireless network.
