摘要： The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node. This approach may also be used for path optimization when a mobile node moves from a trusted to an un-trusted access network.

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： The invention relates to a method for a handover of a mobile node from a non-3GPP to a 3GPP network, and of a mobile node, which is located in a non-3GPP/ 3GPP network. The handover is improved by discovering an appropriate MME and registering the mobile node at the discovered MME, in advance. This includes to first determine the location of the mobile node in the non-3GPP network, so as to be able to detect an MME in the vicinity of the mobile node's location. The 3GPP contexts are then transmitted to the new MME before the handover is performed. Moreover, the invention teaches to change the Serving-Gateway in the 3GPP network before performing a handover, thereby accelerating the handover. When a handover gets likely, the mobile node's location is determined and a new Serving-Gateway is selected. The data path is changed to go via the new Serving-Gateway.

摘要： The invention relates to a method and mobile node capable of detecting whether or not the network to which the mobile node is attached is using a network-based mobility management function for the mobile node or not. In order to enable a mobile node to detect whether the network is using a network-based mobility function for the mobile node, upon establishment of a PDN connection or IP session, the mobile node sends a probe message to the network destined to itself and determines based on the modifications of the probe message returned to the mobile node whether the network is using a network-based mobility function for the mobile node or not.

摘要： The invention relates to a method, mobile node and computer-readable medium for establishing (or pre-establishing) a secure tunnel to an ePDG to prepare for a mobile node attachment or handover to another access network. To reduce the delay of a handover or upon attachment of a mobile node to an access network implied by mechanisms to discover a ePDG, the mobile node maintains a reachability list that can be consulted to identify an ePDG or ePDGs that are reachable in the target access network, i.e. to which the mobile node may establish a secure tunnel. If the mobile node can identify a reachable ePDG for a given access network from the reachability list, the mobile node (pre-)establishes a secure tunnel to the ePDG upon attaching to the given access network. In alternative solutions DNS, DHCP or other mechanism can be used to provide the mobile node with information on ePDGs in its vicinity.

摘要： The invention relates to a method for configuring an IP address of a mobile node attaching to a first access network during an inter-access technology handover from another, second access network. Moreover, the invention relates to a mobile access gateway and a mobile node that participate in this method. First and second access network belong to a network domain offering a network-based mobility function. In order to detect whether a mobile node implements a network-based mobility function a virtual interface discovery is performed by checking whether the mobile node also configures the address according to the home network prefix offered to the mobile node before the handover on its interface to the first access network. In parallel, an address configuration is performed. Based on the detection of whether a virtual interface is implemented at the mobile node, the mobile access gateway may decide whether to use network-based mobility or client-based mobility and change the address configuration.

摘要： The invention relates to a method for establishing by a mobile node an additional session via a connection to a packet data network in a mobile communication network and a mobile node and a packet data network gateway adapted to perform this method. In order to suggest optimized home link detection by a mobile node one aspect of the invention is to delay the decision on whether the mobile node is located on the home link or not. In conventional home link detection, the mobile node checks before sending any binding update on an access interface whether its prefix of the local IP address configured on that access interface is matching a home address prefix received during bootstrapping. According to one aspect of the invention, this home link detection is delayed in that home link detection is based on comparing a home address prefix received during bootstrapping and the advertised local prefix of a router advertisement received after bootstrapping.
摘要翻译：本发明涉及一种用于由移动节点通过连接到移动通信网络中的分组数据网络和适于执行该方法的移动节点和分组数据网络网关建立附加会话的方法。为了建议由移动节点进行优化的家庭链路检测，本发明的一个方面是延迟关于移动节点是否位于家庭链路上的决定。在传统的家庭链路检测中，移动节点在接入接口上发送任何绑定更新之前检查其在该接入接口上配置的本地IP地址的前缀是否与引导过程中收到的归属地址前缀匹配。根据本发明的一个方面，这种家庭链路检测被延迟，因为家庭链路检测是基于比较在引导期间接收到的家庭地址前缀和在引导之后接收到的路由器广告的通告的本地前缀。

摘要： The invention relates to a method for routing packets in a system of packet-switched networks using different internet protocol versions. The system comprises a plurality of home agents, at least one mobile node and at least one correspondent node. A first mobile node is configured with at least one topologically correct internet protocol address of a first internet protocol version and is located in a network supporting at least routing of packets having a header of the first internet protocol version. The method comprises the following steps. Communication is requested with a first correspondent node being configured with at least an internet protocol address of a second internet protocol version and being located in a network supporting at least the routing of packets having a header of the second internet protocol version, by an application on the first mobile node. A first of the plurality of home agents is located in proximity to a direct path between the first mobile node and the first correspondent node, the first home agent being located in a network supporting at least the routing of packets to the first mobile node with the packets having a header of the first internet protocol version and the routing of packets to the first correspondent node with the packets having a header of the second internet protocol version. Bootstrapping is carried out with the first home agent to obtain a first home address of the second internet protocol version and other communication parameters. The first mobile node's location is registered with the first home agent by sending a first binding update message comprising a first mobile node's topologically correct address of the first internet protocol version as care-of address and the first home address as home address; and the first home agent is used in bi-directional tunnelling mode, the outer header of the tunnelled packets using the first internet protocol version and the inner header of the tunnelled packets using the second internet protocol version, for communication with the first correspondent node, with the communication parameters set up in the bootstrapping step and the first home address as home address.

摘要： 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.
