    • In a mobile communication network including a radio base station (50.sub.1) having a service area and a mobile terminal (13) present within the service area, a transmission power control system includes in the fixed station an abnormal terminal detecting part (48, 49, 52) for detecting the mobile terminal as an abnormal terminal when the mobile terminal does not decrease the transmission power after a transmission power control part (37, 48, 52) transmits the mobile terminal with a control signal requesting a decrease of transmission power of the mobile terminal. The abnormal terminal detecting part transmits, when detects the abnormal terminal, the abnormal terminal with a forced communication-disabling signal which is for use in the abnormal terminal in forcedly disabling communication when the abnormal terminal receives the forced communication-disabling signal. The transmission power control part carries out transmission power control of the mobile terminal by transmitting, in dependence upon a signal power of a received signal received from the mobile terminal, the mobile terminal with the control signal. The mobile communication network is typically a CDMA (Code Division Multiple Access) communication network.

    • In an inter-station synchronization method establishing frame synchronization for a radio interval between radio base stations via a mobile station in a cellular mobile communication system constituted by a plurality of zones, a time alignment value corresponding to a mobile station which is in communication with a reference station is measured. An adjustment station receives a transmission signal from the mobile station which is in communication with the reference station, and a radio frame phase difference representing an offset between the received signal and a home intra-station radio frame synchronization signal is measured. A radio frame phase control value is obtained on the basis of a radio frame phase difference measured by the adjustment station and the time alignment value measured by the reference station. The phase of the radio frame synchronization signal of the adjustment station is adjusted in accordance with the obtained radio frame phase control value to be matched the phase with a phase of a radio frame synchronization signal in the reference station.
