摘要： The invention relates to a method performed by a home agent serving a mobile node in a home network of the mobile node upon attachment of a mobile node to the home network as well as to the home agent. Further, the invention also relates to a method for enabling simultaneous use of a plurality of interfaces by a mobile node being attached to a home network through one of the plurality of interfaces and to at least one foreign network through at least another interface of the plurality of interfaces. Moreover, the invention provides a mobile node and a proxy acting on behalf of the mobile node. To enable a mobile node to use a home network and at least one further foreign network for communications the invention suggests the registration of the mobile node's home address or of a network node within its home network as a care-of address in the home network.

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在引导之间接收的家庭地址前缀和在自举之后接收到的路由器广告的通告的本地前缀进行比较。

摘要： A method and apparatus for improved context transfer in heterogeneous networks is presented. Context information is collected from source entities in a first access network by a context transfer manager and transmitted to a context transfer manager of a second access network which forwards the context information to target entities therein, in one of the context transfer managers at least a part of the context information is translated from a format supported in the first access network to another format supported in the second access network. The method may be carried out proactively preceding a handover or reactively following a handover. In one embodiment, context transfer within one access domain is performed directly between access routers, whereas context transfer between different access domains is performed via the context managers. In another embodiment, beacons from access points are counted in order to determine candidates for a pending handover.
摘要翻译：提出了一种用于改进异构网络中的上下文传输的方法和装置。上下文信息是由上下文传送管理器从第一接入网中的源实体收集的，并被发送到第二接入网络的上下文传送管理器，该第二接入网络将上下文信息转发给其中的目标实体，其中一个上下文传送管理器至少部分的上下文信息从第一接入网络中支持的格式转换成在第二接入网络中支持的另一种格式。该方法可以主动地在切换之前或反应地跟随切换之后执行。在一个实施例中，一个接入域内的上下文传送在接入路由器之间直接执行，而不同接入域之间的上下文传送是经由上下文管理器执行的。在另一个实施例中，对来自接入点的信标进行计数，以便确定等待切换的候选。

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 managing the movement of a mobile node from a first router in a first network to a second router in a second network, wherein the mobile node communicates with a corresponding node. In order to enable seamless communication between the mobile node and the corresponding node, the second router is dynamically configured by the first router to transmit a router advertisement message to the mobile node, the router advertisement message comprising a subnet prefix of an IP address of the mobile node, said subnet prefix belonging to the first network. A layer 3 link change as observed by the mobile node can be postponed and a default router of the mobile node can be changed to the new access router immediately after the layer 2 handover, thus enabling very fast handovers without requiring modifications to the mobile node implementations.

摘要： The invention relates to a method for node management in a packet-switched network, wherein a first node acts as a proxy for a second node, both nodes having network-layer addresses and link-layer addresses, the network-layer addresses at the network layer and the link-layer addresses at the link layer being used for communication in the packet-switched network. The method comprises the following steps performed by the first node: The first node receives from the second node a request to receive and forward packets addressed to the second node's network-layer address, whereby the same network-layer address is associated with the first node and the second node, and the first node and the second node have distinct link-layer addresses. The first node advertises to nodes attached to the packet-switched network the first node's link-layer address as a destination address for the second node's network-layer address, while the second node does not advertise. The first node receives in response to advertising, packets destined to the second node's network-layer address having the first node's link-layer address; and forwards packets addressed to the second node's network-layer address to the second node using its link-layer address.
