Abstract:
1. A management method of a radio communication system including a plurality of wireless base stations, said management method comprising: a first step of grasping a communication traffic load situation for each cell that is a coverage range of each of said plurality of said wireless base stations, calculated as an amount of communication traffic load per unit area, the traffic load per unit area being derived on the basis of a propagation characteristic using the transmission power and antenna gain of each base station; and a second step of calculating a communication traffic load evaluation value defined for evaluating said communication traffic load situation of said wireless base stations based on said communication traffic load situation and controlling said communication traffic load situation based on said calculated communication traffic load evaluation value, to control a cell shape and size such that said radio resource load situation of each said cell becomes suitable, said cell shape and size being determined by propagation characteristics and parameters of the wireless base station, said communication traffic load evaluation value being based on a correspondence between a predetermined allotted-load amount and an actually-measured communication traffic load amount of each said cell.
