| 20080298353 | INTERWORKING NETWORK ELEMENT, INTERWORKING SYSTEM BETWEEN THE CSI TERMINAL AND THE IMS TERMINAL AND THE METHOD THEREOF - An interworking network element, an interworking system between the CSI terminal and the IMS terminal and the method thereof, which relate to the communication technology, enable the CSI terminal and the IMS terminal to interwork and the effective bearing link to be established according to the actual requirement. The interworking network element CSI-IW is added at the network of the called side between the CSI terminal and the IMS terminal. The network element receives the session request from the IMS terminal, determines whether there is need to separate the IMS session including the real time media request and non-real time media request into the two IMS sessions including the real time media request and non-real time media request respectively, and chooses the CS domain or the IMS domain to end the call according to the attribute information of the session, the ability for accessing the network, the ability of the terminal etc, so that the real time session can be borne by the CS domain as possible as it can. | 12-04-2008 |
| 20090052438 | METHOD, SYSTEM AND DEVICE FOR PROCESSING SUPPLEMENTARY SERVICES - Method, system and apparatus for processing supplementary services, and MGCF enhanced method and apparatus as well. The method for processing supplementary services is used for supplementary services in packet network when CSI terminal and IMS terminal are interworking. The method includes: after receiving session message relating to supplementary services interworking control function entity extracts detailed content from the session message; according to the detailed content, interworking control function entity executes corresponding supplementary services. The interworking control function entity includes: supplementary service information receiving unit, which receives session message relating to supplementary services and extracts detailed content from the session message; supplementary service operating unit, which executes corresponding supplementary services according to the detailed content. | 02-26-2009 |
| 20090103532 | PACKET NETWORK SYSTEM WITH SESSION CHANGING FUNCTION AND IMPLEMENTATION METHOD AND DEVICE THEREOF - The present invention provides a method for session changing. The method for session changing is designed for session changing during interworking between a first UE and a second UE in a packet network, and includes: reserving, during setup of an initial session between the first UE and the second UE, an interworking control function for logically controlling the interworking on a path of the initial session; and performing, when the interworking control function receives a subsequent session change request, the corresponding session changing operation according to contents of the subsequent session change request. The invention further provides a device for session changing and a packet network system with session changing function. | 04-23-2009 |
| 20090262706 | METHOD, SYSTEM AND DEVICE FOR CONVERTING SESSION CONTROL SIGNALING - A method, system, and device for converting session control signaling are provided. The method includes at least one of the following steps: a first adaptation unit converts a session control signaling message of a circuit switched (CS) session leg into a session control signaling message of an IP multimedia subsystem (IMS) session leg; or the first adaptation unit converts a session control signaling message of an IMS session leg into a session control signaling message of a CS session leg. In embodiments of the present invention, an adaptation unit intercepts a CS signaling message after an inter-mobile switching center (MSC) handover, and converts CS signaling messages to IMS signaling messages and vice versa, so that the IMS domain may continue to control a session after the inter-MSC handover. | 10-22-2009 |
| 20100054159 | METHOD AND DEVICE FOR PROVIDING CALL FORWARDING SERVICE FOR USERS - A method and a device for providing a call forwarding service for users are provided. The method for providing a call forwarding service for users includes the following steps. An IP multimedia subsystem (IMS) network entity receives a call towards a user who accesses from a circuit switched (CS) domain; the IMS network entity acquires a current session connection state of the user or the user's desire of answering the call; and the call forwarding service is provided according to the obtained session connection state of the user or the user's desire. Thus, a call forwarding service in an IMS domain for a called user who accesses from a CS domain is realized. | 03-04-2010 |
