Abstract:
In user terminal 10 of the present invention, connection-cell-selection controlling section 110 measures reception quality of signals respectively transmitted from cells and received by antenna section 108, corrects the reception quality of each of the cells based on a positional relationship between each of the cells and user terminal 10 and based on a moving direction of user terminal 10, and determines a connection cell for user terminal 10 (base station in communication with user terminal 10) based on the corrected reception quality. This configuration lowers a cell switching frequency, while preventing degradation of throughput and the like in a future radio communication system (multilayer cellular radio network).
