Zusammenfassung:	A UE is a mobile station that communicates with a CSCF server. The UE includes a network IF and a mobile network service control unit. By using an IMS signaling bearer established between the UE and the CSCF server, the network IF registers the usage of a predetermined service in the CSCF server. After the usage of the service has been registered by the network IF, the mobile network service control unit releases the IMS signaling bearer. Furthermore, when the CSCF server detects the occurrence of the service to be provided to the UE, the mobile network service control unit re-establishes the released IMS signaling bearer in response to the request from the CSCF server, due to a notification sent from the application server to the UE indicating the occurrence of the service.
