Patent ID: 8897161

Claim:
A wireless communication system that comprises a plurality of base stations including a first base station with which a terminal is configured to communicate and a second base station to which a radio signal transmitted from the terminal becomes an interference power, and is capable of performing handover of a connection destination of the terminal from the first base station to the second base station, wherein the second base station, upon detection of the interference power being more than or equal to a previously set threshold, is configured to multicast transmit information for urging the handover to multicast reception base stations that are at least a part of the base stations including the first base station, and wherein the multicast receiver base station having received the information is configured to specify a terminal that is inferred to exert the interference to the second base station that is a multicast source among the terminals connecting to the local base station and to perform a handover processing on the terminal; and wherein the multicast receiver base station is configured to specify a terminal that is inferred to exert the interference to the second base station based on downlink received power information of the terminal that the base station collects from the belonging terminal.
