摘要： A method of transmitting a data packet on a communication path from a first communication node (CN1, CN2) to a second communication node (LFN1, LFN2) in a mobile network (115). The method includes receiving a route message (1010, 1020) from the second communication node, wherein the route message includes a list of intermediary addresses ({MR1-COA}, {MR1-COA, MR2-COA}) between the first communication node and the second communication node. A preferred communication path is generated in response to the list of intermediary addresses; and at least one data packet is transmitted from the first communication node to the second communication node via this preferred communication path. In this matter, an optimised data path is determined in order to send at least one data packet to an intended receipient (LFN1, LFN2), for example in a nested mobile network scenario.

摘要： A communication network (100) comprises a roaming network node (109) which may move within the network. The network node (109) comprises a network interface (201) for receiving data from a first node (107) of the network (100). The received data may be multicast data or unicast data. The network node (109) further comprises a multicast processor (205) which determines a multicast characteristic of the first node (107) and an address update processor (207) for selecting between a dynamic address update mode and a non-dynamic address update mode in response to the multicast characteristic. In particular, the network node (109) may operate an address update process, such as a route optimisation or a correspondent registration process, conditionally on whether the foreign network (105) is a multicast node or not. This may improve performance and reduce the signalling overhead associated with route optimisation in a communication network.
摘要翻译：通信网络（100）包括可以在网络内移动的漫游网络节点（109）。网络节点（109）包括用于从网络（100）的第一节点（107）接收数据的网络接口（201）。所接收的数据可以是多播数据或单播数据。网络节点（109）还包括确定第一节点（107）的多播特性的多播处理器（205）和用于在动态地址更新模式和非动态地址更新模式之间进行选择的地址更新处理器（207）响应组播特性。具体而言，网络节点109可以有条件地对外部网络（105）是否是组播节点进行地址更新处理，例如路由优化或对应登记处理。这可以提高性能并减少与通信网络中的路由优化相关联的信令开销。
