Abstract
A communication system includes a unicast base station device, a multicast base station device, and a mobile station device. Before receiving information concerning a multicast service, the mobile station device transmits, to a position register server, identification information identifying a reception area in which a multicast service is provided. When receiving incoming call information indicating that information concerning a unicast service has been received, the multicast base station device transmits the incoming call information to the mobile station device. The mobile station device receives the incoming call information even while receiving the information concerning the multicast service.
