    • Methods for detaching a mobile terminal from a mobile communication network. Furthermore, the invention also relates to a mobile terminal and a mobility management entity that perform these methods. The invention is inter alia applicable to a 3GPP LTE-A system following the Evolved Packet System (EPS) architecture. The invention proposes that the detach procedure of a mobile terminal is triggered by the mobile terminal being transferred into idle state. The mobility management entity can trigger the detach procedure in response to this event. The detach procedure may be deferred by a given time span. A detach timer may be configured in the mobile terminal and the mobility entity for this purpose, and upon expiry of the detach timer in the mobile terminal and the mobility management entity, both silently delete the context information related to the mobile terminal's user plane and control plane to detach the mobile terminal.

    • The invention relates to a method for managing the mobility of a mobile node that moves to a different network, but keeps the same IP address. It is proposed to perform route optimization by a Proxy MIP agent on behalf of the MN, thereby shortening the data-path while allowing network-based mobility. At session setup with a correspondent node, the PCC system in the home network derides whether route optimization is to be performed for the communication session. The PMIPa requests relevant information for the route optimization, including the decision for route optimization and the addresses of MN and CN, from the PCC system in the home network, when the MN attaches to the new network area. Accordingly, route optimization is performed by using the Return Routability Procedure according to MIPv6, thereby applying the MN's IP address as Home Address, and the PMIPa's address as Care-of Address of the MN.
    • 本发明涉及一种用于管理移动到不同网络但保持相同IP地址的移动节点的移动性的方法。 建议代表MN代理MIP代理执行路由优化,从而缩短数据路径,同时允许基于网络的移动性。 在与对端节点进行会话建立时,家庭网络中的PCC系统嘲笑是否对通信会话执行路由优化。 当MN连接到新的网络区域时,PMIPa从家庭网络的PCC系统请求路由优化的相关信息,包括路由优化的决定以及MN和CN的地址。 因此,通过使用根据MIPv6的返回可路由性过程来执行路由优化,从而将MN的IP地址作为归属地址,将PMIPa的地址作为MN的转交地址。

    • The invention relates to a method for performing a handover of a mobile node (MN) from a source to a target network, wherein a handover proxy node (HPN) is used to relay the handover of the MN to one of previously measured cells. The MN discovers an appropriate HPN and triggers the handover to the HPN by reporting the measurements together with the HPN ID as destination of the handover. When receiving the Handover Initiation message for handing over the MN to the HPN, the HPN will not proceed with the handover but adapts said handover to indicate a handover of the MN from the HPN to the target base station. Upon receiving the Handover Initiation message in the target network, system resources are configured for data forwarding between the source and target network, and for the data path used by the MN when attaching to the target base station.
    • 本发明涉及一种用于执行移动节点(MN)从源到目标网络的切换的方法,其中切换代理节点(HPN)用于将MN的切换中继到先前测量的小区之一。 MN发现适当的HPN,并通过将测量结合HPN ID作为切换的目的地报告来触发到HPN的切换。 当接收到切换MN的切换启动消息到HPN时,HPN将不进行切换,但是适配所述切换以指示MN从HPN到目标基站的切换。 在目标网络中接收到切换启动消息时,系统资源被配置用于在源网络和目标网络之间进行数据转发,以及用于在附着到目标基站时由MN使用的数据路径。

    • A technology is disclosed in which, when a normal mobile node (that does not newly provide a dedicated function) is used, signaling for reconfiguring a tunnel during a mobile node movement is reduced and, furthermore, packet loss is reduced. In the technology, when an MN moves from under the control of an AR2 that is a movement origin to be under the control of an AR3 that is a movement destination, the AR3 receives an NS transmitted from the MN to the AR2. The AR3 that receives the NS destined to the AR2 transmits a “Location Update” to the AR2. The AR2 that receives the “Location Update” uses an MN management table of the relevant MN and creates “Prefix Information” and returns the “Prefix Information” to the AR3. A tunnel is established between access routers of the AR2 and AR3 through use of the “Prefix Information”, and a packet destined to the MN is transferred to the MN via the tunnel.
    • 公开了一种技术,其中当使用普通移动节点(不新提供专用功能)时,在移动节点移动期间重新配置隧道的信令被减少,并且还减少了分组丢失。 在该技术中,当MN从作为运动起点的AR2的控制下移动到作为移动目的地的AR3的控制下时,AR3接收从MN向AR2发送的NS。 接收发往AR2的NS的AR3向AR2发送“位置更新”。 接收“位置更新”的AR2使用相关MN的MN管理表,并创建“前缀信息”,并将“前缀信息”返回给AR3。 通过使用“前缀信息”在AR2和AR3的接入路由器之间建立隧道,并且去往MN的分组经由隧道传送到MN。

    • The invention relates to a method for reducing the header size of data packets by removing inner headers from the data packets, wherein at least an outer header remains for routing purposes. When removing the inner headers from a data packet, a newly configured address of the receiving and/or the transmitting entity is inserted in the remaining outer header of the data packet. Context information is provided in the receiving entities for reconstructing the removed inner headers, wherein the context information is referred to by the newly configured address that is in the source and/or destination address of the outer header. The reduced data packet is transmitted with only one header, thereby significantly reducing the size of each data packet. The original packet is completely reconstructed at the receiving entity thereby allowing to proceed with the usual processing of each data packet.
    • 本发明涉及一种通过从数据分组中移除内部报头来减少数据分组的报头大小的方法,其中至少一个外部报头保留用于路由目的。 当从数据分组中移除内部报头时,接收和/或发送实体的新配置的地址被插入到数据分组的剩余外部报头中。 在接收实体中提供了上下文信息,用于重构所移除的内部报头,其中上下文信息由位于外部报头的源和/或目的地址中的新配置的地址引用。 减少的数据分组只用一个报头发送,从而显着减少每个数据分组的大小。 原始分组在接收实体处完全重建,从而允许继续对每个数据分组进行通常的处理。

    • 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.
    • 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与安全网关之间的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。
