    摘要: Disclosed is a technique to enable a user equipment at a remote place to perform local IP access to a locally-accessible network with simpler procedure and such a configuration while achieving the efficiency of costs and facility. According to the technique, a network (LIA-PDN 161) capable of dealing with a local IP access by a user equipment (UE 101) is placed on a core network 141. When the UE establishes a PDN connection with the LIA-PDN, the UE simultaneously transmits information concerning the LIA domain network 111 as well, to which the UE wants a local IP access. On the basis of this information, the LIA-PDN establishes a PDN connection with the LIA domain network, and the LIA-PDN transfers a packet, whereby the UE can access the LIA domain network via these PDN connections.

    摘要: The invention relates to a method for ensuring IP session continuity upon a handover of a mobile node to a non-3GPP network, wherein an ongoing IP session of the mobile node goes via a packet data network gateway. For non-3GPP networks it is necessary to discover a security gateway and to then establish the corresponding tunnels to the ePDG to form the new data path; a security tunnel between the mobile node and the security gateway, and an IP tunnel between the packet data network gateway and the security gateway. In order to prepare the handover to possible non-3GPP accesses, the two tunnels are pre-established, however maintained deactivated until their use is actually needed. Accordingly, when handing over to the non-3GPP network, the IP session may be continued without any significant interruption by activating the already established tunnels.

    摘要: Disclosed is a technique to enable a session handover between devices with different key generation functions in an authentication protocol. According to the technique, when a session where a UE (200) receives contents from a contents server (700) is to be handed over to a target node (300), the UE firstly transfers information (session HO information) necessary to the session handover to the target node (Step S1001). The target node performs authentication processing with an authentication server (600) of the network to which the UE is connected and notifies the authentication server of the session HO information transferred from the UE (Step S1003). The authentication server performs authentication for the session handover based on the session HO information, and when the authentication succeeds, the session is handed over from the contents server to the target node, and the contents are distributed to the target node (Step S1005).

    摘要: The invention provides a method for trust relationship detection between a core and access network for a user equipment. The gist is that a security tunnel establishment procedure is used so one entity, be it part of the core network or be it the user equipment itself, is provided with information to determine whether the access network is trusted or untrusted. The information may comprise a first IP address/prefix, which is initially assigned to the user equipment, upon attaching to the access network. The necessary information may further comprise a second IP address/prefix, which is an address/prefix that is allocated at a trusted entity of the core network. Depending which entity determines the trust relationship of the access network, it might be necessary to transmit either the first IP address/prefix or the second IP address/prefix or the first and the second IP address/prefix using the security tunnel establishment procedure.

    摘要: With the deployment of the Mobile Routers, some of the mobile devices would access the IP services, e.g. Remote Local IP Access (LIPA), via the local connections provided by the Mobile Router. In such cases, the mobile devices may be detached from the 3GPP access, and thus lose the capability of receiving certain services, e.g. CS domain related services. This invention presented a solution to allow the mobile device to continue enjoying the services provided via 3GPP access by placing the mobile device into a special state and binding Mobile Router's context with the mobile device's context. In this way, the mobile operator's core network would be able to trigger the mobile device to receive the CS service even its 3GPP access connections are removed.
