    摘要: A system and method for enabling fast authentication for a UE when a handoff occurs during a service in a UMTS-WLAN interworking network are provided. When the UE moves from the UMTS network to the WLAN or vice versa, it can advantageously reuse authentication information used in the old network for authentication and data encryption in the new network.

    摘要: A method and apparatus is provided for reducing a signaling overhead in routing area update performed by a mobile station in a mobile communication system. The method includes grouping cells of the mobile communication system into predetermined cell groups by the network entity, wherein each of the predetermined cell groups is a minimum unit for routing area update; determining cell group identifiers of the cell groups by the network entity; and determining metric information for determining a shape of the routing area by the network entity.

    摘要: A seamless handoff system and method reduces delay and packet loss during handoff of user equipment (UE) from a Wireless Local Area Network (WLAN) network to a Universal Mobile Telecommunication System (UMTS) network. The handoff system and method performs pre-registration and pre-authentication processes before the occurrence of a handoff, buffers packets being delivered to a UE during a handoff period, and forwards the buffered packets to the UE after completion of the handoff, thereby reducing packet loss that can occur during handoff.

    摘要: A method and apparatus for transmitting User Equipment (UE) capability information required for provisioning of a service to a network before a UE requests the service are provided. Before an outgoing or incoming call setup is requested for the UE, a signaling connection is established between the UE and a core network (CN) node to which the UE belongs. After the signaling connection is established, a message including UE capability information of the UE is received and stored for use when the call setup is requested.

    摘要: A method and apparatus for performing handover on a voice call between a packet network system and a circuit network system is provided. Considering a communication environment where a UE cannot simultaneously use radio resources of both the next generation mobile communication system (LTE) and the legacy mobile communication system (e.g., GSM/WCDMA), the present invention proposes an SCSE for performing signal translation between the packet switched network and the circuit switched network and anchoring a voice call in the application level, and supports a continuous voice call using the SCSE.
