PROBLEM TO BE SOLVED: To reduce the number of control times of unwanted handover. SOLUTION: A position information detector 121, a distance calculator 122 and a movement direction and velocity calculator 123 calculate the distance between a mobile communication terminal and each of a plurality of base stations around the communication mobile terminal, and the moving direction of the mobile communication terminal and the velocity thereof, respectively. A transmission path quality detector 124 obtains conditions of deterioration in fading in each of the plurality of surrounding base stations. Then, an offset calculator 125 calculates offset of each of the base stations with respect to a reception signal level on the basis of the obtained various parameters. A handover destination selector 126 selects a base station to be a handover destination on the basis of an offset value calculated for each of the plurality of surrounding base stations, and a reception level of each of the plurality of surrounding base stations.
