    摘要： A method and apparatus is provided for communication between a first terminal capable of using both a Circuit Switched (CS) call and an Internet Protocol Multimedia Subsystem (IMS) session, and a second terminal capable of using the IMS session, in a communication system supporting a Combined CS call and IMS session (CSI service). If the second terminal sends a Session Initiation Protocol (SIP) request (INVITE) message to originate a voice service or a multimedia service including the voice service with the first terminal, a CSI Application Server (AS) of an IMS domain managing the first terminal separates a voice service-related component included in the request message from a multimedia service-related component, and generates and sends first and second request messages to the first terminal. Upon receipt of first and second response messages corresponding to the first and second request messages from the first terminal, the CSI AS generates a combined response message and sends the combined response message to the second terminal.

    摘要： A method and apparatus for performing an inter-RAN L2 handover and an inter-CN L3 handover in a packet-switched network are provided. When a UE connected to an old CN through the old RAN moves to a new RAN belonging to a new CN, an old RAN sends a handover required message to a new RAN. The new RAN acquires a new IP address for the UE from the new CN and sends a handover command message including the new IP address to the old RAN. The old RAN forwards the handover command message comprising an address of the new RAN to the UE. The UE performs an inter-RAN handover in response to the handover command message, to communicate with the old CN through the new RAN and performs an inter-CN handover based on the new IP address to communicate with the new CN through the new RAN.

    摘要： Disclosed is a method and system for mutually exchanging capability information of UEs for communication between a Circuit-Switched (CS) and IMS services (CSI) UE, which can use a CS call for voice communication while using an IMS session for PS service, and an IMS UE which uses an IMS session for both voice communication and PS service. A MGCF performs interworking of capability information between a CS message and an IMS message so that the IMS UE can process UE capability information through an IMS session request/response. When a call request message containing no capability information is created from a UE not supporting capability exchange, a CSI AS transfers the call request message to a peer UE after inserting estimable capability information of the UE into the call request message, and stores capability information of the counterpart UE for the UE.

    摘要： The present invention provides session continuity when a User Equipment (UE) moves from one network to another network. A method and system for providing access to nodes supporting, for example, both Internet Protocol Version 4 (IPv4) and Internet Protocol Version (IPv6) on a network supporting only one of the IP versions are provided. In addition, both network based mobility and UE based mobility mechanisms are supported to allow a UE supporting dual stack mobility access to a network supporting only one of IPv4 or IPv6. The invention provides for a reduction of header overhead and signaling overhead.
