摘要： Methods and apparatus for optimizing IP multicast data transmission in a mobile IP environment include a Foreign Agent that is capable of receiving an information request associated with a host membership report sent from a mobile node and for providing information identifying a Home Agent associated with the mobile node to a multicast router process to enable the multicast router process to send a join host group message to the Home Agent. A Home Agent receives the join host group message and sends the join host group message toward a source of IP multicast data packets. Both the Foreign Agent and the Home Agent set up a data path between the Home Agent and the Foreign Agent, thereby enabling data packets addressed to the multicast group address to be forwarded by the Home Agent to the Foreign Agent. The Home Agent does not replicate multicast IP data packets addressed to the multicast group address prior to being forwarded by the Home Agent to the Foreign Agent. Rather, the multicast router process is responsible for replication and transmission of multicast IP data packets to one or more network segments associated with the Foreign Agent.
摘要翻译：用于在移动IP环境中优化IP多播数据传输的方法和装置包括能够接收与从移动节点发送的主机成员资格相关联的信息请求并且用于提供标识与移动节点相关联的归属代理的信息的外部代理到组播路由器进程以使得组播路由器进程向归属代理发送连接主机组消息。归属代理接收加入主机组消息，并将连接主机组消息发送到IP组播数据包的源。外部代理和归属代理都在归属代理和外部代理之间建立数据路径，从而使寻址到多播组地址的数据包由归属代理转发给外地代理。在由归属代理转发给外部代理之前，归属代理不复制寻址到多播组地址的多播IP数据包。相反，组播路由器进程负责复制和传输组播IP数据包到与外地代理相关的一个或多个网段。

摘要： Methods and apparatus for authenticating a mobile node are disclosed. A server is configured to provide a plurality of security associations associated with a plurality of mobile nodes. A packet identifying a mobile node may then be sent to the server from a network device such as a Home Agent. A security association for the mobile node identified in the packet may then be obtained from the server. The security association may be sent to the network device to permit authentication of the mobile node. Alternatively, authentication of the mobile node may be performed at the server by applying the security association.

摘要： Multi-operator networking techniques are provided for allowing two or more operators to share a wireless local area network (WLAN). In particular, mobile access gateway functionality is integrated in a wireless network controller of a WLAN that is accessible to first and second operators. Operator-specific tunnels are created through the network for each of the first and second operators that link a core network of each of the first and second operators with an associated client device. Packets are then forwarded between the core networks of the first and second operators and their associated client devices via the operator-specific tunnels.

摘要： Systems and methods for providing identity management and mobility management are disclosed. The management scheme provides mobility in multi-device and multi-homed deployments. A collection of three identities, a device identity, a link layer identity, and a user identity, can be used to provide mobility for a number of devices under different use scenarios. In one embodiment, a method is disclosed for receiving messages from a mobile device at a mobility gateway, the messages including identifiers such as a user identifier, a link layer identifier, and a device identifier where identifiers are stored or retained at the mobility gateway. When a subsequent network attach request is received including one or more identifiers, a reconnection can occur, based on a result of comparing the stored identifiers with the received one or more identifiers.

摘要： A method is provided in one example implementation and the method includes identifying through a home bearer manager that an Internet Protocol (IP) address has been previously sent to an access terminal, the IP address being issued by a visited bearer manager as a result of the access terminal requesting registration in a visited network. The method further includes communicating the IP address to the access terminal in response to the access terminal registering in a home network. The registrations in the home and the visited network allow a plurality of packets to be communicated to the access terminal via the IP address. In more specific embodiments, the IP address serves as a care of address (CoA) address and a home IP address concurrently. The IP address can be exchanged via a mobile IP (MIP) exchange. The home and visited bearer managers are independent or interdependent.

摘要： A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; de-capsulating the data packet; identifying whether the data packet is an upstream data packet; identifying whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; and offloading the data packet from the backhaul link. In more specific embodiment, the method can include identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; and communicating the data packet to a second network element. In other examples, the method can include identifying that the data packet is a downstream data packet; identifying a service to be performed for the data packet that cannot be performed at the first network element; and communicating the data packet to a second network element.

摘要： Communicating packets along a bearer path includes providing a home network address and a visited network address to an access terminal. The home network address corresponds to a home anchored bearer path anchored at a home network of the access terminal, and the visited network address corresponds to a visited anchored bearer path anchored at a visited network. Packets are received from the access terminal. The packets are communicated along the home anchored bearer path if the packets use the home network address. The packets are communicated along the visited anchored bearer path if packets use the visited network address.
