摘要： Methods and apparatus for performing proxy registration on behalf of a node with a Home Agent supporting Mobile IP are disclosed. A first registration request is composed on behalf of the node and transmitted to the Home Agent via a first Local Mobility Anchor, wherein the first Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with the first Local Mobility Anchor. When the node moves within a region or between regions, the node is re-registered. Specifically, a second registration request is composed and transmitted to the first Local Mobility Anchor when the node moves within the region associated with the first Local Mobility Anchor. When the node moves into a second region associated with a second Local Mobility Anchor and outside the first region associated with the first Local Mobility Anchor, a second registration request is composed and transmitted to the Home Agent via the second Local Mobility Anchor, wherein the second Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with second first Local Mobility Anchor.

摘要： Methods and apparatus for establishing an optimized route between a Mobile Node and a Correspondent Node are disclosed. In particular, a Correspondent Node is notified of the location of a Mobile Node, thereby enabling the Correspondent Node to communicate directly with the Mobile Node. This is accomplished by sending a HOTi message protected in IPSec transport mode from the Mobile Node to a Home Agent associated with the Mobile Node for modification and transmission of a modified HOTi message to the Correspondent Node. The Mobile Node then receives a HOT message protected in IPSec transport mode from the Home Agent associated with the Mobile Node, the HOT message being received from the Home Agent associated with the Mobile Node after modification has been performed by the Home Agent on an initial HOT message received by the Home Agent from the Correspondent Node.

摘要： Methods and apparatus for establishing an optimized route between a node and a Correspondent Node are disclosed. In a Mobile Router supporting Mobile IP, the Mobile Router having one or more networks associated therewith, a method of establishing a route between one or more nodes associated with one of the networks of the Mobile Router and a Correspondent Node includes composing a HOTI message on behalf of at least one of the nodes, which is sent from the Mobile Router to a Correspondent Node via a Home Agent supporting the Mobile Router. The Mobile Router sends a COTI message to the Correspondent Node on behalf of the node. The Mobile Router receives a HOT message from the Correspondent Node. It then receives a COT message from the Correspondent Node, thereby enabling a binding between the node(s) and the Correspondent Node to be generated such that data packets transmitted between the node(s) and the Correspondent Node can be routed between the node(s) and the Correspondent Node without being routed via the Home Agent.

摘要： Methods and apparatus for providing a centralized source of session keys to be shared by a Home Agent and a Mobile Node are disclosed. In accordance with one aspect of the invention, a Mobile Node registers with a Home Agent supporting Mobile IP by sending a registration request to the Home Agent. The Home Agent sends a request message (e.g., access-request message) to a AAA server, the request message identifying the Mobile Node. The AAA server then derives key information from a key or password associated with the Mobile Node. The AAA server then sends a reply message (e.g., access-reply message) to the Home Agent, the reply message including the key information associated with the Mobile Node, thereby enabling the Home Agent to derive a shared key to be shared between the Mobile Node and the Home Agent from the key information. The Home Agent derives a key from the key information, the key being a shared key between the Mobile Node and the Home Agent. A registration reply is then sent to the Mobile Node. When the Mobile Node receives a registration reply from the Home Agent, the registration reply indicates that the Mobile Node is to derive a key to be shared between the Mobile Node and the Home Agent. The Mobile Node then derives a key to be shared between the Mobile Node and the Home Agent from key information stored at the Mobile Node. The Mobile Node may initiate “re-keying” by sending a subsequent registration request to the Home Agent.
摘要翻译：公开了用于提供由归属代理和移动节点共享的会话密钥的集中源的方法和装置。根据本发明的一个方面，移动节点通过向归属代理发送注册请求来向支持移动IP的归属代理注册。归属代理向AAA服务器发送请求消息（例如，访问请求消息），该请求消息标识移动节点。然后，AAA服务器从与移动节点相关联的密钥或密码导出密钥信息。 AAA服务器然后向归属代理发送应答消息（例如，接入应答消息），该回复消息包括与移动节点相关联的密钥信息，从而使归属代理能够导出要在移动台之间共享的共享密钥节点和归属代理从关键信息。归属代理从密钥信息中导出密钥，密钥是移动节点和归属代理之间的共享密钥。然后将注册答复发送到移动节点。当移动节点从归属代理接收到注册请求时，注册应答指示移动节点将导出要在移动节点和归属代理之间共享的密钥。移动节点然后从存储在移动节点处的密钥信息中导出要在移动节点和归属代理之间共享的密钥。移动节点可以通过向归属代理发送后续注册请求来启动“重新键入”。

摘要： Methods and apparatus for performing optimizations for a mobile network device such as a Mobile Node or Mobile Router supporting multiple links to a Home Agent (or Correspondent Node in a Mobile IPv6 environment) are disclosed. During the registration process, link characteristics are transmitted in the registration request. From the link characteristics, it is possible to determine whether the mobile network device has roamed from a high to a low bandwidth link, or vice versa. A first set of optimizations may be performed when the mobile network device has roamed from a high to a low bandwidth link, while a second set of optimizations may be performed when the mobile network device has roamed from a low to a high bandwidth link. Some optimizations may be performed during the establishment of a TCP session, while others may be performed during or upon completion of the Mobile IP registration process.

摘要： Methods and apparatus for optimizing Mobile VPN communications are disclosed. When a data packet is transmitted between a Mobile Node that is a member of a VPN and a Correspondent Node, the data packet is transmitted between the Mobile Node and a Home Agent via a Mobile IP tunnel without transmitting the data packet via a VPN tunnel.
