<p>A controller device (300) which controls a first radio base station, which uses a plurality of predetermined frequencies for downlink communication, and a second radio base station, which uses the plurality of frequencies for downlink communication. The controller device (300) receives power information and location information from the first radio base station, the power information indicating, for each frequency, the power of the signal arriving at the radio terminal in the communication area of the first radio base station from the second radio base station, and the location information indicating the location of the radio terminal. The controller device (300) is provided with an identifying unit (321) which, based on the power information and location information received from the first radio base station, identifies an interference location and identifies an interference frequency, the interference location being the location where the power of the signal arriving at the communication area is greater than orequaltoapredeterminedvalue, and the interference frequency being the frequency of the signal arriving at the interference location.</p> |
