A method and a system assign a speech channel difficult to cause interference in a radio mobile station and in both in the radio mobile station and a radio base station. A channel number is set, a usability judgment threshold value is read out to be compared with a reception field intensity of a selected speech channel. If the reception field intensity is relatively high, a preference of the speech channel is lowered. If the reception field intensity is relatively low, the channel is notified to the radio mobile station. If interference is present in the radio mobile station, the preference is again lowered and otherwise, process of establishing call connection is initiated.
