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 an embodiment, an existing transport protocol connection though a mobile device is recognized as having entered a state of disconnect. A lowest received sequence number is determined from received messages to be transmitted over a disconnected transport protocol connection. A disconnect acknowledgement message with a receive window of zero and a sequence number of one less than the lowest received sequence number is transmitted. The disconnect acknowledge message with a receive window of zero and a sequence number of one less than the lowest received sequence number is continued to be transmitted until the transport protocol connection exits the disconnect state to a connect state.

摘要： Methods and apparatus are disclosed for performing layer 2 authentication of a Mobile Node supporting Mobile IP in an SSG based network. Layer 2 information including at least one of a MAC address and username associated with the Mobile Node is obtained. An orphaned host object including the layer 2 information (e.g., MAC address) is then generated. The orphaned host object is then unorphaned when an IP address associated with the layer 2 information (e.g., MAC address) is received such that the unorphaned host object includes the IP address and the layer 2 information.

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 supporting a session in Mobile IP are disclosed. A Mobile Node sends a first Mobile IP message identifying the Mobile Node to a Home Agent, wherein the first Mobile IP message indicates to the Home Agent that the Mobile Node is requesting dynamic configuration of a Mobile-Home authentication key to be shared between the Mobile Node and the Home Agent during the session. A Mobile-Home authentication key to be shared between the Home Agent and the Mobile Node is obtained or generated by the Mobile Node and the Home Agent, where the Mobile-Home authentication key is not valid after the session has ended or during another session. The Home Agent sends a second Mobile IP message to the Mobile Node, the second Mobile IP message including a lifetime associated with the session, wherein the lifetime indicates a lifetime of the key, thereby enabling the Mobile Node to register with the Home Agent using the Mobile-Home authentication key to be shared between the Home Agent and the Mobile Node during the session.

摘要： An invention is disclosed that enables proxy Mobile IP registration to be performed in a secure manner. Various security mechanisms may be used independently, or in combination with one another, to authenticate the identity of a node during the registration process. First, an Access Point receiving a packet from a node verifies that the source MAC address identified in the packet is in the Access Point's client association table. In addition, as a second mechanism, the Access Point ensures that a one-to-one mapping exists for the source MAC address and source IP address identified in the packet in a mapping table maintained by the Access Point. As a third mechanism, a binding is not modified in the mobility binding table maintained by the Home Agent unless there is a one-to-one mapping in the mobility binding table between the source MAC address and the source IP address. Similarly, the Foreign Agent may also maintain a mapping between the source IP address and the source MAC address in its visitor table to ensure a one-to-one mapping between a source IP address and the associated MAC address. The MAC address is preferably transmitted in a MAC address extension to the registration request and registration reply packets. In this manner, the Access Point, Home Agent, and Foreign Agent may ascertain the node's MAC address and ensure a one-to-one mapping between the IP address and the MAC address during the registration process.
摘要翻译：公开了能够以安全的方式执行代理移动IP注册的发明。各种安全机制可以独立地或彼此组合地使用以在注册过程期间认证节点的身份。首先，从节点接收分组的接入点验证分组中标识的源MAC地址在接入点的客户端关联表中。另外，作为第二种机制，接入点确保了由接入点维护的映射表中的源MAC地址和源IP地址中的一个一对一映射。作为第三种机制，在归属代理维护的移动性绑定表中，绑定不会被修改，除非在源MAC地址和源IP地址之间的迁移绑定表中存在一对一的映射。类似地，外地代理还可以在其访问者表中保持源IP地址和源MAC地址之间的映射，以确保源IP地址和相关MAC地址之间的一对一映射。 MAC地址优选地以MAC地址扩展发送到注册请求和注册应答分组。以这种方式，接入点，归属代理和外部代理可以确定节点的MAC地址，并确保在注册过程中IP地址和MAC地址之间的一对一映射。

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 registration on behalf of a session associated with a mobile node are disclosed. The mobile node composes a registration request including a NAI identifying a userID and a sub-NAI that uniquely identifies a session associated with the NAI. The mobile node then sends the registration request. When the Home Agent authenticates the mobile node, the Home Agent returns an IP address associated with the session. The NAI and sub-NAI may then be mapped to this IP address in a mobility binding table associated with the Home Agent as well as a visitor table associated with the Foreign Agent to which the mobile node has roamed.
