<p>Base stations concerned with soft hand-over with respect to a mobile terminal notify sums of control values to a wireless network controller at intervals of the predetermined number of frames. In each base station, the control values are obtained by decoding common transmission power control signals transmitted by the mobile terminal at intervals of a time slot shorter than the frame. The mobile terminal notifies ratios of signal power to noise power regarding common pilot signals transmitted by the base stations. The wireless network controller selects one of the base stations as a reference station according to the ratios of signal power to noise power. The wireless network controller instructs the base stations to match transmission power of the base station(s) other than the reference station to that of the reference station.</p> |
