When a mobile station enters into a service area of a non-subscriber communication system and uses it with a roaming service, the mobile station receives system information from a repeater station of the communication system, recognizes user interface information included in the system information, and switches the user interface of the subscriber communication system to a user interface of the non-subscriber communication system corresponding to the recognized user interface information. Thus, the mobile station can effectively use the roaming service and thereby conveniently use the mobile communication system.
