Abstract: A method of supporting mobility 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, which incorporates its address and forwards the message to a dynamic host configuration protocol (DHCP) Server. The DHCP Server and access node analyze 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 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 tunneling required.

Abstract: A mobile communication network comprises a home agent supporting mobility of a mobile entity by generating bindings between a home address of the mobile entity and a care of address of the mobile entity. A mapping processor provides at least one set of mappings between a potential future care of address for a mobile entity and a real time characteristic criterion. The mappings may for example be determined in response to previous movements of the mobile entity in the communication network. A processor determines a real time characteristic and the home agent is arranged to change a binding between the home address and a current care of address in response to the at least one set of mappings and the real time characteristic, and without receiving binding updates from the mobile entity. The approach may allow support for mobility of a mobile entity while reducing signalling in support of mobility.

Abstract: A method of validated communication The present invention provides a method of validated communication between a mobile network node (MNN) and a correspondent node (CN) via at least a first mobile router (MR). The method is characterized by employing an extended return routability checking procedure (XRRP) wherein an MNN test initiation (MNNTI) message is sent by the MR, and a MNN test (MNNT) message is sent by the CN. This adds to the security of requiring the home and care-of addresses being consistent as noted previously in standard RRPs, by enabling the generation of binding update validation keys based on receipt on any or all of the three HoT, CoT and MNNT test messages. The method is further characterized by sending from the MR an extended binding update (XBU), comprising the MNN's address (MNNA). By extending the binding update to include the MNNA in this manner, validated CN/MNN route optimization can be achieved.

Abstract translation: 一种经过验证的通信方法本发明提供一种经由至少第一移动路由器（MR）的移动网络节点（MNN）和通信节点（CN）之间的有效通信的方法。 该方法的特征在于采用扩展返回可路由性检查过程（XRRP），其中由MN发送MNN测试发起（MNNTI）消息，并且由CN发送MNN测试（MNNT）消息。 这增加了通过基于在任何或所有三个HoT，CoT和MNNT测试消息上的接收来生成绑定更新验证密钥来增加要求归属和转交地址与标准RRP中所述一致的安全性。 该方法的特征还在于从MR发送包括MNN地址（MNNA）的扩展绑定更新（XBU）。 通过以这种方式扩展绑定更新以包括MNNA，可以实现经验证的CN / MNN路由优化。

Abstract: 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 optimized data path is determined in order to send at least one data packet to an intended recipient (LFN1, LFN2), for example in a nested mobile network scenario.

Abstract: A method of transmitting at least one data packet from a communication node in a data communication network. The method includes receiving (920) a request at a communication node, to transmit at least one data packet to a first destination address and searching (930) for the (first) destination address in a cache of the communication node. A determination (960) of an intermediary address of the destination address is made. The destination address is then replaced with the intermediary address and the steps of searching, determining and replacing are repeated, until no new intermediary address is found. The at least one data packet is then transmit (970) to the destination address via the identified intermediary address(es). A communication unit (corresponding node) communication message and method for building a linked binding cache are also described. In this manner, an optimised data path is determined in order to send at least one data packet to an intended recipient, for example in a nested mobile network scenario.
