摘要： The invention relates to a method for handovers between at least two network mobility domains. The domains are part of a system with local mobility anchors and a mobile node being connectable with each of the network mobility domains. A first connection is established between the mobile node and a first network mobility domain; and the local mobility anchor of the first network mobility domain is designated a session mobility anchor. A second connection between the mobile node and a second network mobility domain of the at least two network mobility domains is established. The step of establishing comprises a step of locating wherein a local entity pertaining to the second network mobility domain locates the session mobility anchor to which the mobile node is designated. The step of locating the session mobility anchor comprises the following step carried out by the local entity: retrieving a session mobility anchor identification. The session mobility anchor identification is retrieved from at least one of: a transmission sent by the mobile node to the second network mobility domain, and a data base comprising a mobile node identification identifying the mobile node. The data base stores the mobile node identification related to a session mobility anchor identification of the session mobility anchor dedicated to the mobile node. The local entity comprises at least one of: a mobile access gateway of the second network mobility domain, the local mobility anchor of the second network mobility domain which provides a visited local mobility anchor, or another entity pertaining to and being connected to the second network mobility domain. Further, the invention relates to a local mobility anchor adapted to retrieving the identification according to the invention. Additionally, the invention relates to a retrieval unit for supplying a requesting local mobility anchor with requested session mobility anchor information, the retrieval unit comprising the data base. Finally, the invention relates to a computer program product implementing the inventive method when running on a programmable processor.
摘要翻译：本发明涉及一种用于在至少两个网络移动性域之间切换的方法。这些域是具有本地移动锚点的系统的一部分，并且移动节点可与每个网络移动性域连接。在移动节点和第一网络移动性域之间建立第一连接; 并且第一网络移动性域的本地移动锚点被指定为会话移动锚点。建立移动节点与至少两个网络移动性域的第二网络移动性域之间的第二连接。建立步骤包括一个定位步骤，其中属于第二网络移动性域的本地实体定位移动节点被指定到的会话移动锚节点。定位会话移动锚点的步骤包括由本地实体执行的以下步骤：检索会话移动锚点标识。从移动节点发送到第二网络移动性域的传输和包括识别移动节点的移动节点标识的数据库中的至少一个检索会话移动锚定标识。数据库存储与专用于移动节点的会话移动锚的会话移动锚标识相关的移动节点标识。本地实体包括以下中的至少一个：第二网络移动性域的移动接入网关，提供被访问的本地移动性锚的第二网络移动性域的本地移动锚点，或与第二网络有关并且连接到第二网络的另一个实体移动域。此外，本发明涉及适于检索根据本发明的标识的本地移动锚。另外，本发明涉及一种用于向请求的本地移动锚点提供所请求的会话移动锚点信息的检索单元，所述检索单元包括数据库。最后，本发明涉及一种在可编程处理器上运行时实现本发明方法的计算机程序产品。
