When deterioration in throughput is detected, it is determined whether a factor of the deterioration is deterioration in channel quality or concentration of traffic. If the factor of the deterioration in the throughput is the concentration of the traffic, it is determined whether or not a base station to become a switching candidate for a serving sector is present around, and if it is present, switching of the serving sector is requested to a serving base station. In contrast, if the factor of the deterioration in the throughput is the deterioration in the channel quality, it is determined whether or not a base station to become an adding candidate for the serving sector is present around, and if it is present, adding of the serving sector is requested to the serving base station.
