摘要： For data flow between a subnet (16) of a data network (4) and a mobile node (6), re-routing such that the data flow goes through a different access network via a different network access point (40) is described. The method comprises the steps of ending provision of a first address binding currently being provided between the mobile node (6) and a first access network (20) where the address is dependent upon a type of the first network access point (24). The method includes the step of starting provision of a second address binding between the mobile node (6) and a second access network (36) dependent upon a type of the second network access point (40). Alternatively, or in addition, steps of removing and adding address entries on a routing table are described. The data network (4) may for example be the Internet, the subnet (16) may be an Internet protocol (IP) subnet, and the access networks (20,36) may be a UMTS network, HiperLAN, Bluetooth, IEEE 802.11b, Ethernet etc.

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： A method of supporting mobility (400, 500) in an Internet Protocol (IP)-based data network. The method comprises the steps of generating a first stateful IP autoconfiguration message at a mobile node, whereby the message includes an address capable of use for routing maintenance. The mobile node transmits, the generated message to a first access node (240), which incorporates its address and forwards the message to a dynamic host configuration protocol (DHCP) Server. The DHCP Server (320) and access node (240) analyse the message to determine a route to deliver data to and/or from the mobile node. One or more route update message are triggered from said access node and said DHCP server to a number of network elements (230) between said access node and said DHCP server in the IP based data network to support mobility in an IP domain with minimum bandwidth use and minimum tunnelling required. A DHCP Server (320) and an access node (250) such as DHCP Relay are also described. In this manner, the inherent configuration flexibility of stateful autoconfiguration addresses is provided, in contrast to, say, other micro-mobility management schemes where the IP address is manually configured.
摘要翻译：一种在基于互联网协议（IP）的数据网络中支持移动性（400,500）的方法。该方法包括以下步骤：在移动节点处产生第一状态IP自动配置消息，由此消息包括能够用于路由维护的地址。移动节点将生成的消息发送到第一接入节点（240），该第一接入节点（240）并入其地址并将该消息转发到动态主机配置协议（DHCP）服务器。 DHCP服务器（320）和接入节点（240）分析消息以确定向移动节点和/或从移动节点传送数据的路由。一个或多个路由更新消息从所述接入节点和所述DHCP服务器触发到所述接入节点和所述基于IP的数据网络中的所述DHCP服务器之间的多个网络元件（230），以支持具有最小带宽使用的IP域中的移动性并需要最小的隧道。还描述了DHCP服务器（320）和诸如DHCP中继之类的接入节点（250）。以这种方式，提供了有状态自动配置地址的固有配置灵活性，与其他手动配置IP地址的其他微移动性管理方案相反。

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.

The method includes receiving a route message from the second communication node, wherein the route message includes a list of intermediary addresses between the first communication node and the second communication node. A preferred communication path is generated (3014, 3038) in response to the list of intermediary addresses; and at least one data packet is transmitted (2050) from the first communication node to the second communication node via this preferred communication path. Various communication nodes, a communication system, various communication messages, methods for constructing and sending messages and a method for building an extended binding cache are also described.
