摘要
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.
