    • A method and apparatus for routing communications traffic in a Proxy Mobile IP communications network. A Mobile Node is attached to a first Proxy Mobile Agent, and an optimized route is established between the Mobile Node and a Corresponding Node via the first Proxy Mobile Agent. When the Mobile Node subsequently attaches to a second Proxy Mobile Agent, a determination is made that the Mobile Node is no longer attached to the first Proxy Mobile Agent. As a result of the determination a request is sent from the first Proxy Mobile Agent to the Corresponding Node to cancel the route optimization. In one embodiment, packets from the Corresponding Node are bi-cast from the Proxy Mobile Agent to the Home Agent and the Mobile Node. The Proxy Mobile Agent determines that the Mobile Node is no longer attached to if packets are not returned from the Home Agent.

    • The present invention concerns a method of handling a Local Break Out (LBO) session taking place in a first network between a user equipment and a corresponding node (CN). The invention addresses the problems that arise when using only one IP address in the user equipment and the user equipment moves to a second network. This is, for the downlink packets, solved by the steps of: converting, in a node in the first or the second network, the IP address of the downlink packets from an LHoA to a Global Home Address (GHoA) and routing, from the first node, directly or indirectly to a second node in the second network, any downlink packets being sent from the corresponding node, so that the downlink packets will arrive at the user equipment having a GHoA. For the uplink packets the problem is solved by converting, in a node in the first or the second network, the IP address of the uplink packets from a GHoA to an LHoA and routing, from the second node, directly or indirectly to the first node, any uplink packets being sent from the user equipment; so that the uplink packets will arrive at the corresponding node with a source address that is an LHoA. The invention also concerns nodes for handling an LBO session.
    • 本发明涉及处理在用户设备和对应节点(CN)之间的第一网络中发生的本地中断(LBO)会话的方法。 本发明解决了在用户设备中仅使用一个IP地址并且用户设备移动到第二网络时出现的问题。 对于下行链路分组,这是通过以下步骤来解决的:在第一或第二网络中的节点中将从LHoA到全球归属地址(GHoA)的下行链路分组的IP地址转换为 第一节点直接或间接地连接到第二网络中的第二节点,从对应节点发送的任何下行链路分组,使得下行链路分组将到达具有GHoA的用户设备。 对于上行链路分组,通过将第一或第二网络中的节点中的上行链路分组的IP地址从GHoA转换到LHoA并且从第二节点直接或间接地路由到第一节点来解决问题 ,从用户设备发送的任何上行链路分组; 使得上行链路分组将以具有LHoA的源地址到达相应的节点。 本发明还涉及用于处理LBO会话的节点。

    • A basic idea is to use the AAA infrastructure to assign (S3) an appropriate DHCP server to DHCP client for the DHCP service, and transferring DHCP-related information over the AAA infrastructure for authenticating (S1) and authorizing (S4) the DHCP client for DHCP service with the assigned DHCP server. Instead of the more complex DHCP server discovery process known from the prior art, the AAA infrastructure, and more particularly a suitable AAA server or equivalent AAA component, is used for assigning an appropriate DHCP server to the DHCP client. Consequently, there is no longer any mandatory dependency on the DHCP discovery-related messages. The invention preferably provides AAA protocol support for facilitating assignment of appropriate DHCP servers and providing an out-of-band key agreement protocol for DHCP clients and servers by carrying DHCP related informaion facilitating the bootstrapping of DHCP authentication extension (RFC3118).
    • 一个基本思想是使用AAA基础设施为DHCP服务器为DHCP客户端分配(S3)适当的DHCP服务器,并通过AAA基础设施传输与DHCP相关的信息,以认证(S1)并授权(S4)DHCP客户端 DHCP服务与分配的DHCP服务器。 使用现有技术已知的更复杂的DHCP服务器发现过程,而不是使用AAA基础设施,更具体地,合适的AAA服务器或等效的AAA组件来为DHCP客户端分配合适的DHCP服务器。 因此,不再需要依赖于与DHCP发现相关的消息。 本发明优选地提供AAA协议支持,以便于分配适当的DHCP服务器,并通过携带DHCP相关信息为DHCP客户端和服务器提供带外密钥协商协议,以便于DHCP认证扩展(RFC3118)的引导。
