PROBLEM TO BE SOLVED: To avoid or reduce the interferences of frequency channels among the cells of base stations while allowing the base stations to be installed or removed at an arbitrary and uneven locations. SOLUTION: A central control station 1 decides if interferences occur among the cells of the base stations 2, based on a list in the base stations 2 relating to the mobile stations 3 created, based on the received electric waves. Based on the decision result, the central control station 1 also decides, if it is possible to assign a frequency channel from a predetermined number of frequency channels with respect to each of the base station 2, with which the interference between the cells can be avoided, and determines a priority sequence for interference avoidance for each combination of the base stations 2, based on the decision result. The central control station 1 decides the frequency channel to be assigned to the each base station 2, in accordance with the priority sequence. COPYRIGHT: (C)2008,JPO&INPIT
