The server alters a frequency of the base station, and a transmitted-power quantity of the base station and the terminal based on these measured results to improve the radio-link quality, and reduces interference with a neighboring radio system. When a load is concentrated on a network of a specific radio operator, handover instruction is given to the terminal from the server to realize a load distribution. When the server detects excessive radio interference between the radio operators, it notifies occurrence of a fault, an interference quantity, a quantity of the transmitted power that the base station should attenuate, and the frequency that the base station should alter to the radio operator that becomes an interference source.04-25-2013
