ABSTRACT:
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.
