In a channel assignment method for a mobile communication system, a plurality of speech communication channels, assigned to perform radio communication between base stations respectively arranged in a plurality of cells constituting a service area and mobile stations in the cells, are classified into first and second groups. The speech communication channels of the second group are classified into a plurality of subgroups. The base stations are then allowed to use speech communication channels belonging to the first group and to one of the subgroups in the second group. Each of the base stations are caused to assign one of the speech communication channels belonging to the first group and one of the subgroups in the second group, which are allowed to be used, to a corresponding one of the mobile stations.
