摘要:
A trigger is armed to a predetermined detection point (DP) of a basic call state model controlled for each call by a switching system so that a service control point (SCP) can be unconditionally activated. The SCP stores service control information for each time band in such a manner as to correspond to each user. When a first control signal is received from the switching system, the DP which is determined by the service control information is notified to the switching system and the switching system arms the trigger to this DP. When the state of the call shifts to a specific DP to which the trigger is armed because a called party is busy or does not answer, for example, the switching system sends a second control signal to the SCP, and the SCP notifies a terminating terminal equipment determined by the service control information in response to the second control signal.

The objective of the invention is to provide a mobile communication control method and mobile communication system in which mobile IPv6 and SIP are integrated by a core network of 3GPP2. In the mobile communication system, the mobile node MN executes a registration procedure for a Care-of-Address acquired in a visited network by the communication between the mobile node and a home agent server HA, executes a registration procedure for the Care-of-Address by the communication between the mobile node and an SIP server, and executes a communication procedure for session establishment by the communication between the mobile node MN and a correspondent node not through the home agent server but through the SIP server.

This invention provides a method of implementing a multi-party conference service (MPCS) using broadcast/multicast service of a wireless communications system used for a conference focus, the context of a corresponding broadcast/multicast service session is generated based on the media flow information, multicast service session information and MPCS information. The generated context of the broadcast/multicast service session is then sent respectively to at least one content provider server, at least one mobile terminal and the broadcast/multicast service controller so that the one or more mobile terminals acquires the content media flow through the broadcast/multicast service session.

A server 3b for controlling a gateway 2 connecting a transport layer and an IP network has the function of accessing a service control point (SCP) 4 via a service control gateway 1a. A server 3 for controlling terminals on the IP network stores information of correspondence between telephone number of a terminal and the IP address. When a signal including number information which requires an access to the SCP is received from a terminal 11 managed by the server 3a, an interrogation request is multicasted to the other servers each having the function of accessing the SCP. A server which has sent a response signal accesses the SCP via the service control gateway to provide an IN service process.

An address translator includes an SIP message detecting function. Upon detection of an SIP message, the address translator sends the SIP message to an SIP address translator. The SIP address translator extracts addresses for translation, and makes a query to the address translator. The SIP address translator translates an IP address included in the SIP message, using translation information of the address translator. Thus, an SIP communication is accomplished between terminals belonging to different regions in association of the address translator and the SIP address translator.

A user's home is connected to a plurality of service providers by a plurality of VPNs, and traffic sent and received by a home terminal is filtered to an appropriate VPN so as to avoid communication disturbance due to IP address duplication by reducing unnecessary traffic. A terminal sends terminal information to inquire a management server about a SIP URI of VPN based on the terminal information sent by the terminal as well as user information. The management server notifies a router about the SIP URI of VPN corresponding to the notified information. The router establishes the VPN based on the notified SIP URI. The router maintains a mapping between the established VPN and a source terminal of a UPnP message, and then transfers traffic sent and received by each terminal after VPN establishment.

A communication method and system allowing MN (mobile nodes) to acquire a home address in a visited network. The communication system includes a home network installed with a home agent for holding mobile terminal location information and, a visited network installed with a radio communications device for communicating with that mobile terminal, and gateway equipment in the visited network for forming an interface with the home network. The radio communication device includes an access request transfer unit for forwarding access requests from a mobile terminal of the visited network to the gateway equipment which makes an acquisition request to the home agent for an identifier of that mobile terminal, and forwards that acquired identifier to that mobile terminal.
