In each cell of a mobile communication system with reuse of a plurality of radio channels by dynamic channel allocation, a base station repeats measuring an interference signal level of each channel of candidate channels during a predetermined interval for storage as a first stored level and then further during the interval for storage as a whole as a second stored level when the first stored level is lower than a predetermined reference level and selects, based on such stored levels, an allocated channel for communication with a mobile station in the cell. If the first stored level is lower than a lower reference level, further measurement is unnecessary. Alternatively, the base station repeats measurement and storage as regards different ones of the candidate channels at a regular and a shorter refresh interval. This invention is applicable to channel reuse in a microcellular mobile communication system with its central base station made to measure interference signal levels of different radio channels at regular and shorter refresh intervals. <IMAGE> |
