A zone selection method for a mobile radio communication system selects one among many radio zones and switches a primary radio zone where a given mobile terminal exists to the selected radio zone without concentrating incoming and outgoing calls at a specific radio zone. The method prioritizes the radio zones according to the reception levels of signals transmitted from the radio zones and received by the mobile terminal as well as the performance of the radio zones including the call connection ratios and channel usage ratios of the radio zones, and then, the method selects the one having the highest priority among the prioritized radio zones.
