A radio switching system includes a mobile subscriber; a base station controller for controlling a transmission and reception of a signal of the mobile subscriber within an own cell; a mobile switching center connecting with a plurality of the base station controllers; and a home location register for storing home zone information whether or not the mobile subscriber is a subscriber of home zone services. The mobile switching center judges whether or not a registration is accepted with respect to a location registration request inside/outside a home zone of the mobile subscriber, based on home zone information sent from the home location register.
