Abstract
In idle handover control, the reception quality of a synchronized pilot channel is classified into quality class “ ” with which data can be received without any error, quality class “ ” with which data can be received within an allowable error range, or quality class “ ” with which data is difficult to receive with high quality, and different thresholds, i.e., 6 dB, 4 dB, and 2 dB, are respectively set for these quality classes. It is checked whether the reception quality of another pilot channel as a synchronization establishment candidate is higher than that of the synchronized pilot channel by a threshold corresponding to a quality class into which the synchronized pilot channel is classified or more. If it is determined that the reception quality of the synchronization establishment candidate is higher by the threshold or more, handover processing is performed. Otherwise, synchronization with the synchronized pilot channel is maintained without handover processing.
