Management method for a cellular network using cell load

A managing server 1 and a propagation characteristic computing server 3 grasp a load situation for each cell that is a coverage range of each of a plurality of APs 4a to 4d, calculate an evaluation value defined for evaluating the load situation, and take a control of the load situation of each cell so that this evaluation value is minimized. The control of load situation is a control for altering a shape (including size) of each cell, and further, specifically, a control for making a cell alteration so that the above-mentioned evaluation value is minimized, by performing processes such as regulation of the transmission power of the AP, alteration of the installation position of the AP and addition of the AP. This allows the load of each cell (AP) to be regulated most suitably.
