摘要： Methods and apparatus for supporting broadcast traffic in Mobile IP are disclosed. When a Mobile Node registers via a Foreign Agent supporting Mobile IP, the Foreign Agent receives a registration request from a Mobile Node and sends the registration request to a Home Agent. A registration reply received from the Home Agent has a network mask extension including a network mask associated with the home address of the Mobile Node. The Foreign Agent then sends the registration reply to the Mobile Node. Alternatively, the Mobile Node may register via a collocated care-of address, in which case the registration reply is received directly from the Home Agent. Once the Mobile Node has obtained its network mask, it may send packets such as broadcast packets, as well as roam to its Home Agent. Additionally, in accordance with various embodiments, the Foreign Agent duplicates broadcast packets for transmission to Mobile Nodes, rather than receiving the duplicated packets from the Home Agent. In this manner, broadcast traffic in a Mobile IP environment is optimized.

摘要： Methods and apparatus for generating and transmitting dynamically generated session keys are disclosed. A key distribution center generates a session key between the key distribution center and a first mobility entity (e.g., an access point). Once the session key between the key distribution center and the access point is transmitted to the access point, the access point retrieves a shared session key between the access point and a Mobile Node from the key distribution center, which is then transmitted to the Mobile Node, enabling the Mobile Node to connect to the network. Similarly, either the Mobile Node or its Home Agent retrieves a session key between the key distribution center and the access point from the key distribution center, enabling a shared session key between the Home Agent and the Mobile Node to be obtained from the key distribution center. The Mobile Node (or Home Agent) then transmits the shared session key to the Home Agent (or Mobile Node). Once the shared session key is obtained by both the Home Agent and the Mobile Node, the shared session key is used to authenticate registration messages (e.g., including registration request and reply packets). In this manner, dynamically generated session keys may be used to securely transmit registration messages in a Mobile IP environment.
摘要翻译：公开了用于生成和发送动态生成的会话密钥的方法和装置。密钥分配中心在密钥分配中心和第一移动性实体（例如，接入点）之间生成会话密钥。一旦密钥分配中心和接入点之间的会话密钥被发送到接入点，则接入点从密钥分发中心检索接入点和移动节点之间的共享会话密钥，然后将其发送到移动节点，使移动节点能够连接到网络。类似地，移动节点或其归属代理在密钥分发中心和密钥分配中心的接入点之间检索会话密钥，从而能够从密钥分配中心获得归属代理和移动节点之间的共享会话密钥。移动节点（或归属代理）然后将共享会话密钥发送到归属代理（或移动节点）。一旦共享会话密钥由归属代理和移动节点获得，则共享会话密钥用于认证注册消息（例如，包括注册请求和应答分组）。以这种方式，动态生成的会话密钥可以用于在移动IP环境中安全地传送注册消息。

摘要： In one embodiment, accounting information for a mobile node operating according to Mobile IP Protocol is updated. A network device that supports Mobile IP composes a request packet for the mobile node. The request packet identifies the mobile node and includes at least one counter associated with accounting information pertaining to the mobile node. The request packet is then sent to a server adapted for performing accounting. The server then logs the accounting information for the mobile node. The server may then send a reply packet to the network device acknowledging logging of the accounting information pertaining to the mobile node. A bill for Mobile IP services may then be generated from the accounting information.

摘要： Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address, which may be allocated by the Foreign Agent. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes or to a cluster of Mobile Nodes (e.g., associated with the care-of address) via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded directly to one of the Mobile Nodes assigned that Home Address. Alternatively, when an address such as the care-of address is associated with multiple Mobile Nodes, the Foreign Agent may perform a second level of dispatching such that the server request is dispatched to one of the Mobile Nodes in the cluster.

摘要： Methods and apparatuses for obtaining home agent assignment. The invention uses a DNS query to signal a request for dynamic home agent assignment. The DNS query will cause a content routing device to be notified that home agent assignment is being requested. The content routing device can then use predetermined metrics to select a home agent. A DNS response will then be sent back to the device that initiated the DNS query containing the IP address of the selected home agent.

摘要： Methods and apparatus are disclosed that enable a Home Agent to be dynamically assigned to a mobile node. A Mobility Agent supporting Mobile IP enables a mobile node to be registered with either the Mobility Agent or another “local” Home Agent, by receiving a registration request packet from the Mobile Node indicating that a key to be shared by the Mobile Node and an agent with which the Mobile Node is registering is requested. In addition, the agent with which the Mobile Node is registering (e.g., local Home Agent) may be assigned. For instance, a local Home Agent may be assigned if load balancing among multiple Home Agents is desired. A key to be shared by the Mobile Node and the agent with which the Mobile Node is registering is obtained. The key to be shared by the Mobile Node and the agent with which the Mobile Node is registering is then stored. A registration reply packet is then sent to the mobile node including the key to be shared by the Mobile Node and the agent with which the Mobile Node is registering. The mobile node may then re-register with the agent (e.g., local Home Agent) using the key.

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： Methods and apparatus for processing a registration request from a Mobile Node that has roamed to a Foreign Agent supporting Mobile IP are disclosed. In a first one of a plurality of Home Agents supporting Mobile IP, a registration request addressed to a virtual Home Agent address associated with the plurality of Home Agents is received. The registration request is then sent to a second one of the plurality of Home Agents such that the second one of the plurality of Home Agents creates a binding between the Mobile Node and the Foreign Agent. The first one of the plurality of Home Agents creates a temporary binding between the Mobile Node and the Foreign Agent. A registration reply is then received from the second one of the plurality of Home Agents. The temporary binding is then updated to create a permanent binding when the registration reply is received from the second one of the plurality of Home Agents. The registration reply is then sent to the Foreign Agent identified in the temporary binding.
