Communication Control Method, Communication System and Communication Control Apparatus

A communication system including a plurality of wireless base stations having adaptive array antennas and a communication control apparatus for controlling the plurality of wireless base stations, wherein

• a first wireless base station, among the plurality of wireless base stations, which directs a beam to a wireless communication apparatus comprises:
• a first transmission unit for transmitting information on a first weighting factor adopted for generation of the beam to the communication control apparatus,
• the communication control apparatus comprises:
• a first reception unit for receiving the information on the first weighting factor transmitted from the first wireless base station;
• a communication interference region presumption unit for presuming a communication interference region between the first wireless base station and a second wireless base station, among the plurality of the wireless base stations, neighboring the first wireless base station based on the first weighting factor received;
• a second weighting factor calculation unit for calculating a second weighting factor to be adopted for beam generation of the second wireless base station so as to avoid the presumed communication interference region;
• and
• a second transmission unit for transmitting information on the second weighting factor calculated to the second wireless base station, and
• the second wireless base station comprises:
• a second reception unit for receiving the transmitted information on the second weighting factor;
• and
• a beam generation unit for generating a beam based on the received information on the second weighting factor.

A communication control apparatus for controlling a plurality of wireless base stations having adaptive array antennas, comprising:
