ABSTRACT:
A base station frequency assigning system for a mobile communication system which is capable of assigning operational frequency for each base station in a short time is realized. Base stations 11(1) to 11(N) are grouped into small groups, which are grouped into large groups. A base station control station 13 notifies each small group of the respectively predetermined frequencies and each base station 11 in the respective groups measures the field intensity of each frequency by means of a frequency measuring unit 23. A frequency determining unit 24 determines the optical frequency and notifies the base station control station 13 of this frequency. A frequency assignment prohibiting information instructing unit 25 may limit in advance a frequency assignment of the base stations 11 which cannot obtain an adequate result of measurement. A frequency assignment can be quickly performed by grouping the base stations 11.
