Relay station, base station, mobile station, communication system, and communication method
First Claim
1. A relay station capable of communicating with a first base station, a second base station, and a mobile station, the relay station comprising:
- a relay unit configured to relay communication between the first base station and the mobile station;
a receiving unit configured to receive load information concerning the second base station;
a changeover unit configured to change, from the first base station over to the second base station, a communication counterpart of the mobile station, communicating with the mobile station via the relay unit, the communication counterpart being changed based on the received load information; and
a transmitting unit configured to transmit to the first base station, base station information that indicates the second base station, whereinthe changeover unit controls the first base station to change the communication counterpart based on the base station information transmitted by the transmitting unit.
