Claim:
A mobile communication network apparatus comprising: a transfer destination table which associates a base station with a transfer destination telephone number of an incoming call for a mobile station located in a call-regulated area of the base station and an incoming call transfer control circuit transferring the incoming call for the mobile station to the transfer destination telephone number based on the transfer destination table, wherein the base station transmits a transfer setting request, which activates a transfer of the incoming call for the mobile station located in the call-regulated area of the base station to the transfer destination telephone number and the incoming call transfer control circuit activates the transfer upon receiving the transfer setting request, wherein the transmitting circuit of incoming call transfer request/release notifies a transfer setting release request for releasing transfer setting to the mobile communication network apparatus when the incoming call transfer control information is not received for more than a fixed time, when an intensity of radio wave becomes equal to or less than a predetermined threshold value, or when a power-down switch is activated.
