摘要： The present invention discloses a technique for providing a packet recovery method, and the like, capable of starting packet recovery processing without waiting for a wasteful latency (time-out) at a mobile terminal by giving notice of information on a packet discard in a gateway device in real time, thereby enabling improvement in communication quality and communication efficiency. According to the technique, there is provided a packet recovery method for recovering a packet discarded by an intermediate device positioned on a communication path between a mobile terminal and a correspondent node of the mobile terminal among packets exchanged between the mobile terminal and correspondent node, the method including: a step of causing the intermediate device to transmit a discard notification message to the mobile terminal based on information on a communication flow for which transmission of the discard notification message indicating that the packet has been discarded is required; and a step of causing the mobile terminal to transmit the correspondent node a retransmission request message for requesting retransmission of the discarded packet based the discard notification message.

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： 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.
摘要翻译：本发明涉及一种用于在移动节点切换到非3GPP网络时确保IP会话连续性的方法，其中移动节点的正在进行的IP会话经由分组数据网络网关进行。对于非3GPP网络，有必要发现安全网关，然后建立到ePDG的相应隧道，以形成新的数据路径; 移动节点和安全网关之间的安全隧道，以及分组数据网络网关和安全网关之间的IP隧道。为了准备到可能的非3GPP接入的切换，两个隧道是预先建立的，然而保持停用，直到实际需要使用它们为止。因此，当切换到非3GPP网络时，可以通过激活已经建立的隧道来继续IP会话而没有任何明显的中断。

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： Provided is a technique to provide a handover processing method that allows a mobile terminal to be handed over seamlessly while preventing occurrence of double reservation. The method includes a step where a mobile terminal (100) decides to connect to a desired access network (113) and detects the possibility of occurrence of a network-initiated handover processing performed by a predetermined device of the communication network as one of the controlling entities, and a step where the mobile terminal transmits a connection request message requesting a connection to the desired access network, the connection request message including information to maintain the connection with the access network with which the mobile terminal is currently connecting, to a base station disposed in the desired access network based on a detection result of the detection step.
