PURPOSE:To reduce the probability of production of interference and deterioration during communication while suppressing increase in a call loss ratio small comparatively in the mobile communication system executing dynamic channel allocation. CONSTITUTION:Each base station places priority to each channel to measure interference power of each channel and places higher priority when the power is less than a prescribed power and places lower priority when the power is a prescribed power or over. Then in the case of channel allocation, a channel with higher priority is selected first and when a desired wave versus interference wave power ratio is a prescribed threshold ratio or over, the channel is allocated. In this system, a different threshold level of the desired wave versus interference wave power ratio is set depending on the priority. |
