Patent ID: 8077600

Claim:
A radio communication system comprising: a plurality of radio base stations each of which has a predetermined number of sectors and is disposed so that a radio zone covered by each sector does not overlap another radio zone, each of the plurality of radio base stations further comprising a backup radio base station, wherein in normal operation, different frequency bands are generated by dividing a predetermined frequency bandwidth by the predetermined number of sectors, and the generated different frequency bands are set for each of the predetermined number of sectors, when a failure occurs, different frequency bands are generated by dividing the predetermined frequency bandwidth by a total number of the predetermined number of sectors and a predetermined number of radio base stations among the plurality of radio base stations, and are allocated to the predetermined number of sectors and a backup radio base station of a radio base station having a failed sector, and the output power of the backup radio base station of the radio base station having the failed sector is adjusted so as to overlay the radio zone covered by the failed sector.
