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 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： In one embodiment, a method includes receiving, at a visited network node, policy for a roaming terminal from a home network of the roaming terminal. The policy is associated with a home Internet Protocol (IP) address of the roaming terminal. The visited network node applies the policy in the visited network to data packets that include the home IP address. Applying the policy to a data packet encompasses either enforcing the policy at the node that applies the policy or sending data that indicates the policy to a different node that applies the policy based on the data sent, or both.

摘要： Communicating packets along a bearer path includes receiving a home network address and a visited network address at an access terminal. The home network address corresponds to a home anchored bearer path anchored at a home network of the access terminal. The visited network address corresponds to a visited anchored bearer path anchored at a visited network. The access terminal determines whether to use the home anchored bearer path or the visited anchored bearer path, and communicates packets using the home network address or the visited network address in accordance with the determination.

摘要： Methods and apparatus for dynamically generating a set of Mobile IP keys are disclosed. The set of Mobile IP keys is dynamically generated using an existing HLR/AuC authentication infrastructure. This is accomplished, in part, by obtaining an International Mobile Subscriber Identity (IMSI) that uniquely identifies a particular Mobile Node. Once a set of Mobile IP keys is generated from authentication information associated with the IMSI, the Mobile Node may register with its Home Agent using the set of Mobile IP keys.

摘要： Methods and apparatus for preventing an IP address from being assigned to a client implementing a protocol such as DHCP are disclosed. This is particularly useful in an environment such as a Mobile IP environment in which a network device (e.g., Access Point) performs proxy registration on behalf of the client. When the client transmits a detection packet to detect whether its IP address is still valid (e.g., whether it is on the same sub-network on which the IP address was allocated), a response is transmitted to the client that indicates that the client is still on its home network. This response is transmitted regardless of whether the client is still on its home network. Since the client believes it is still on its home network, a new IP address will not be assigned to the client. As a result, an existing Mobile IP session will not be interrupted.
摘要翻译：公开了防止IP地址被分配给实现诸如DHCP之类的协议的客户端的方法和装置。这在诸如移动IP环境的环境中特别有用，其中网络设备（例如，接入点）代表客户机执行代理注册。当客户端发送检测分组以检测其IP地址是否仍然有效（例如，是否在分配了IP地址的同一子网上）时，会向客户端发送一个响应，指示客户端仍然在其家庭网络。无论客户端是否仍在其家庭网络上，都会发送此响应。由于客户端认为它仍然在其家庭网络上，因此不会将新的IP地址分配给客户端。因此，现有的移动IP会话将不会中断。

摘要： Methods and apparatus for enabling a Mobile Node supporting mobile IP to roam without an assigned IP address and receive lookups indicating that a Corresponding Node wants to send information to the Mobile Node are disclosed. A name lookup may be sent from a Corresponding Node to a Home Agent that has previously registered the Mobile Node. The name lookup may be sent through an intermediate device, including a Domain Name Server, such that the intermediate device contacts the Home Agent. During the name lookup process, an IP address is allocated to the Mobile Node and a data path is established between the Home Agent and the Mobile Node via a Foreign Agent. When the lookup is completed successfully, the Home Agent sends the IP address allocated to the Mobile Node in the name lookup process to the device requesting the lookup. The IP address of the Mobile Node may then be used by the Corresponding Node to “push” information to the Mobile Node.
摘要翻译：公开了一种使支持移动IP的移动节点在没有分配的IP地址的情况下漫游并且接收指示相应节点想要向移动节点发送信息的查找的方法和装置。名称查找可以从对应节点发送到先前注册了移动节点的归属代理。名称查找可以通过包括域名服务器在内的中间设备发送，使得中间设备联系归属代理。在名称查找过程中，将IP地址分配给移动节点，并且通过外部代理在归属代理和移动节点之间建立数据路径。当查询成功完成时，归属代理将名称查找过程中分配给移动节点的IP地址发送到请求查找的设备。移动节点的IP地址然后可以被对应节点用来将信息“推送”到移动节点。
