Abstract
A radio communication system includes a first radio base station, second radio base stations, and mobile stations. Each of the mobile stations measures a first reception characteristic value and a second reception characteristic value for respective radio waves. The first radio base station determines the radio base station to which each of the mobile stations should connect, according to the first reception characteristic value, and classifies the mobile stations into a first mobile-station group and a second mobile-station group according to the second characteristic values. The first radio base station specifies a correction value according to the distribution of differences in the first reception characteristic value so as to reduce the sum of the number of mobile stations that belong to the second mobile-station group and that should connect to the first radio base station and the number of mobile stations that belong to the first mobile-station group and that should connect to second radio base stations.
