摘要： 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.

摘要： When a first base station serving a mobile communication terminal in a standby mode, a first neighbor list is acquired from the first base station and stored in a memory. If the serving base station is changed in a standby mode from the first base station to a second base station, a second neighbor list is acquired from the second base station. When the second base station is serving the mobile communication terminal in a standby mode, the communication quality between the mobile communication terminal and each second peripheral base station listed in the acquired second neighbor list, and between the terminal and each first peripheral base station listed in the stored first neighbor list. Based on the measurement results, a peripheral base station that satisfies a preset condition is selected as a hand-off destination candidate.
