摘要： A network system for communicating with mobile nodes has multiple gateways that can operate with each using a different access technology. In an IPv6 system, the access gateways each provide an interface identifier to the mobile nodes using the same one or more keys and a hash so that different access gateways can provide the same interface identifier regardless of the access technology used. The access gateways can have multiple options for using keys and/or hashes to provide an interface identifier such that the method for determining the interface identifier is configurable.

摘要： Systems and methods for intercepting and redirecting requests are provided. More particularly, certain information is identified in a packet and the packet is redirected to a specified server. The information that is redirected may be bound for a server in a network that a mobile node is currently visiting, and it is advantageous to fulfill the request in another network instead. The request is redirected to the other network; however, the response to the request may be modified changing the source address and other information so that the response appears to have originated from the server in the visited network to which the mobile node sent the request. Load balancing may also be incorporated when redirecting requests from one or more mobile nodes.

摘要： Methods and systems are provided for recovering from an interruption in, or failure of, an L2TP tunnel (160) connection, such that reconnection of the tunnel is not required. According to various embodiments, redundant storage (238) of tunnel state information is used to avoid having to reconnect an interrupted or failed tunnel session. According to various other embodiments, extraction of sequence numbers from a peer L2TP endpoint server is achieved by subdividing the set of all available sequence numbers into an appropriate number of divisions, and sending a control message having a sequence number from each of the divisions to the peer endpoint server (410) to elicit a response.
摘要翻译：提供方法和系统用于从L2TP隧道（160）连接中的中断或故障中恢复，使得不需要重新连接隧道。根据各种实施例，使用隧道状态信息的冗余存储（238）来避免重新连接中断或故障的隧道会话。根据各种其它实施例，从对等L2TP端点服务器提取序列号是通过将所有可用序列号的集合细分为合适数目的分段来实现的，并且从每个分区向具有序列号的控制消息发送到对等端点服务器（410）引出响应。

摘要： The functionalities of one or more of a mobility management entity (MME), serving gateway (SGW), and packet data network gateway (PGW) can be provided in a single device on the network. In the access gateway different functional elements are implemented as services and they can be configured on the same device. For example, the SGW and PGW can be configured on the same device. When user equipment UE connects from a home network, it is possible for the MME to choose the same SGW and PGW. This combined SGW and PGW can implement a single session for the UE, thereby capable of providing a savings in resources, allowing additional capacity, and allowing reduced latency and increased throughput because fewer hops are made on the network. This session acts as a SGW on the ingress side and a PGW on the egress side of the access gateway.

摘要： Methods and systems for providing network connectivity in wireless networks are provided. This network connectivity can involve a mobile node being able to connect with more than one network at the same time and supporting multiple protocol sessions. Additionally, modifications can be made to allow a mobile node to have multiple IP addresses. These modifications include using a packet data network identifier along with a network control protocol to allow a network device to provide to user equipment (UE) multiple packet data network connections. The network device can be a access gateway or HPRD serving gateway (HSGW) that sets up the PDN connections for the UE. The packet data network identifier can be used to distinguish between multiple PDN connections for a UE.

摘要： Systems and methods for providing fast handoff support by transferring information are provided. Additionally, a generic protocol message format is presented which allows the transfer of information used in the handoff. The generic protocol allows a gateway to request contexts or session information and send information that allows tunnel setup and mapping to other connections. The session, tunnel, and mapping information allow the gateways to switch packet processing operations without causing disruption to the packet flow. Further, in inter-gateway handoffs or inter-access network handoffs, fast and seamless handoffs are provided so the mobile station keeps the same IP address and the session continues.

摘要： A system and method for providing services to packet flows in a communication network. The services include enhanced charging, stateful firewalls, traffic performance optimization (TPO) and advanced services such as content differentiated charging, per- subscriber stateful firewalls, and VPNs, for example. A gateway can be used to route each packet flow through the services on a per-subscriber basis by inspecting accounting messages and checking subscriber profiles prior to setting up a new packet flow session. By directing the packet flow through the services requested latency can be reduced as well as the need to have equipment for each session regardless of whether the service is provided to the packet flow. The services can be provided in-line as well.

摘要： Systems and methods are provided that allow voice and data traffic to be shifted from one chassis to other chassis without interrupting service. Geographic Redundancy (GR) is an inter-chassis redundancy, where the chassis may be a home agent, a packet data serving node, or any combination of wireless networking devices. Additionally, each chassis (310, 342) can have one or more partitions that handle subscriber session traffic and a corresponding redundant partition on a different chassis. The redundant chassis partition can take over all or a portion of the functionality of the active chassis partition if the active chassis or any critical peer servers/gateways communicating with the active chassis should fail. This provides users with uninterrupted service in the case of some failures.
摘要翻译：提供了允许语音和数据业务从一个机箱转移到其他机箱而不中断服务的系统和方法。地理冗余（GR）是机架间冗余，其中机箱可以是归属代理，分组数据服务节点或无线联网设备的任何组合。另外，每个机箱（310,342）可以具有处理用户会话通信的一个或多个分区和在不同机箱上的对应的冗余分区。如果主动机箱或与主动机箱通信的任何关键对等服务器/网关都将失败，冗余机箱分区可以占用主动机箱分区的全部或部分功能。这在一些故障的情况下为用户提供不间断的服务。

摘要： Methods and systems for providing redundancy in servicing packet data communications within wireless mobile data networks are disclosed. More particularly, the method and system provide a redundant Home Agent with the ability to assume the role of the primary Home Agent in the event of a primary Home Agent network, software, or other failure. The redundancy allows the Home Agent services to remain functional even in the event of a failure of one of the Home Agents in the redundant group, which may be composed of one or more Home Agents. The Home Agents can use a service redundancy protocol which is composed of messages that are sent between the redundant group of Home Agents. The messages allow the Home Agents to, for example, back up call session information, check on the status of one another, and share priority information.
摘要翻译：公开了用于在无线移动数据网络内提供分组数据通信服务中的冗余的方法和系统。更具体地说，该方法和系统提供冗余归属代理，其能够在主归属代理网络，软件或其他故障的情况下承担主归属代理的角色。即使在冗余组中的一个本地代理发生故障时，本地代理服务也可以保持功能，冗余组可以由一个或多个本地代理组成。归属代理可以使用由在冗余归属代理组之间发送的消息组成的服务冗余协议。这些消息允许归属代理例如备份呼叫会话信息，检查彼此的状态并共享优先级信息。
