摘要： The invention consists of a new registration and authentication protocol for between a Mobile Node and a Home Agent. The new protocol uses a novel messaging sequence to request registration, authentication and authorization of the Mobile Node when it is located on a foreign network, and the novel protocol will avoid some of the standard registration and authentication protocol messages in order to eliminate the problems associated with re-transmission errors.

摘要： Packet data serving networks may use different wireless access technology, such as General Packet Radio Service (GPRS), Universal Mobile Telecommunications System (UMTS), cdma2000, Wireless Local Area Network (WLAN), WiMax, IxEV-DO, I xEV-DV, or other such standards based specification. A wireless local area network technology can also include any one of 802.11 (a), 802.1 l (b), 802.1 l (g), or Bluetooth. The method and apparatus in accordance with the present invention includes a home mobility anchor receiving a message from a serving mobility agent located on a packet data serving network where the mobile node is located. The present invention relies on the form and content of information packet sent from the serving mobility agent to identify the access technology being used on the packet data serving network. After determining the access technology type used on the packet data serving network, the home mobility anchor takes appropriate actions to authenticate the mobile node user, perform accounting, communicate with a proxy server or an Accounting, Authentication, and Authorization (AAA) server associated with the packet data home network, or perform other necessary actions to process information packets for the mobile node.

摘要： The present invention utilizes the AAA infrastructure to dynamically allocate the various parameters needed to establish the security association between the Foreign Agent and the Home Agent. The present invention uses the AAA server as a central entity to dynamically generate and distribute the chosen security association parameters needed to support the Foreign Agent and Home Agent security association based on a request from the Foreign Agent. The AAA server can also dynamically assigns a unique SPI value to the Foreign Agent and Home Agent pairs. The various parameters that can be allocated in the present invention include a FA-HA shared secret key or a public/private key pair, an authentication algorithm and mode, a FA-HA secret key lifetime, and security parameter index or security index values. The present invention also can assist in making sure that the Foreign Agent and the Home Agent stay synchronized with respect to their security association.

摘要： The present invention solves these problems with a new proxy binding update request and proxy binding acknowledgement messages having new indicators and identification information. Namely, the home agent/local mobility anchor will exchange proxy binding update messages and proxy binding acknowledge messages that include information such as mobile node identification (MN-ID), home network prefix (HNP), but can also include selective information fields such as, access type, handover indicator (HO), and interface identification (interface ID). By including new access type, indicator, and identification information, the local mobility anchor can respond to a binding update request message with a better understanding of the new connectivity request from the mobile node. The invention also includes a binding revocation message with expanded trigger field information sent from the local mobility anchor to the mobile access gateways so the mobile access gateway can determine if the network resources should be revoked, and the manner in which it can optimize usage of the network resources by revoking the network resources in a certain time and manner.

摘要： The present invention solves communication disruption problems during the hand-off transition period by using a pre-handoff registration of a new foreign agent on behalf of the mobile node The pre-handoff registration message should: (1) identify itself as a pre-hand off registration message, (2) indicate direction of traffic for the pre-handoff registration time period, and (3) specify a lifetime or time period when the pre-handoff registration request will continue to be considered valid The local mobility anchor will accept traffic using the pre-handoff registration care-of address depending on the directionality indicator, but the communication traffic to or from the mobile node will not be disrupted during the transition period. Because the care-of address for the mobile node on the new foreign network can be used to direct communication traffic to or from the mobile node during this transition time period, no disruption of service will be encountered.
摘要翻译：本发明通过使用代表移动节点的新外国代理人的切换前注册来解决切换过渡期间的通信中断问题。切换前注册消息应当：（1）将自身识别为前置（2）指示切换前注册时间段的流量方向，以及（3）指定切换前注册请求将被认为有效的生命周期或时间段本地移动锚点将接收流量根据方向性指示符使用切换前注册转交地址，但是在过渡期间到达或来自移动节点的通信流量将不会被中断。由于新的外部网络上的移动节点的转交地址可以用于在该转换时段期间将移动节点的通信流量引导到移动节点，也不会遇到服务中断。

摘要： The present invention provides a system and method to selectively negotiate different delivery styles for different types of packets sent from the Mobile Node to the Foreign Agent, which will allow the Mobile Node to negotiate a delivery style that will permit the Foreign Agent to transmit certain selected outbound traffic directly without reverse tunneling that traffic back to the home network. Specifically, the present invention allows the Foreign Agent to distinguish between certain types of BC/MC packets that are designated to be processed and routed to their destinations by the Foreign Network directly, as opposed to reverse tunneling the outbound traffic from the Foreign Agent back to the Home Agent on the home network. By selecting processing by the Foreign Network, the efficiency of the system will improve because the transmission of outbound traffic and inbound responses will not need to be tunneled through the Home Network.
摘要翻译：本发明提供了一种系统和方法，用于选择性地协商从移动节点向外部代理发送的不同类型的分组的不同传送风格，这将允许移动节点协商一种将允许外地代理发送某些所选择的出站流量直接没有反向隧道，流量返回家庭网络。具体地说，本发明允许外地代理人将由外国网络直接指定为被处理和路由到其目的地的某些类型的BC / MC分组进行区分，而不是将来自外部代理的出站业务反向隧道化归属代理在家庭网络上。通过选择外部网络的处理，系统的效率将会提高，因为不需要通过家庭网络来传输出站流量和入站响应。
