In order to select a base station with the high possibility of being requested from a communication terminal to transmit data, using a downlink state report transmitted from the communication terminal to a base station, each base station determines whether the base station is a base station with the high possibility of being requested from the communication terminal to transmit data, and transmits the determination result to a control station as control information of flow between the control station and base station, and the control station transmits data to the base station. <IMAGE> |
