摘要： Systems and methods for establishing and operating data sessions between mobile subscriber units and packet data servers on a wireless communication network are presented. Some aspects described herein are directed to preventing the loss of an initial configuration request signal (e.g. under the LCP protocol) from a packet data server to a mobile subscriber prior to successful establishment of a radio air link to the mobile subscriber. Other aspects are directed to detecting the presence or absence of a radio air link to the mobile subscriber as a determinant of whether the packet data server is to send a configuration request signal to the mobile subscriber, or whether the packet data server should withhold the request signal until the air link is established. Some or all aspects presented are suitable for use in 3G or CDMA-2000 systems using the A10/A11 communication control protocol and the PPP data communication protocol.

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 for 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 Home Agent services to remain functional in the case 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 be located in geographically separate areas to ensure that a network outage event in one geographic area does not cause subscriber services to be impacted.

摘要： Methods and systems are provided for filtering packets in a wireless communication system in the to-mobile subscriber direction. This filtering is at least in part based on RF circuit state information. For example, a packet filter is used that either permits or denies packets from reaching a mobile subscriber based on whether there is already an established RF circuit to provide packets to the mobile subscriber. Alternatively, or in addition, the packet filter may consider the history of circuit state transitions associated with a particular mobile subscriber, the percentage (or aggregate number) of available airlink resources that are currently in use, and/or the length of time associated with the dormancy of a mobile subscriber's RF connection. In various embodiments, the packet filter may cause one or more packets to be sent to a mobile subscriber using a special data channel that does not require the establishment of an RF circuit.

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： Systems and methods for bridging packet flows to bypass call legs and/or tunnels are provided. A tunnel initiator, which can be an access gateway, a foreign agent, and a mobility anchor point, for example, provides a bypass for certain packets that have a destination serviced by the same tunnel initiator. The bridge allows the packets to bypass a backhaul loop and reduces latency and frees bandwidth for other purposes in the network. The bridging can be implemented in a tunnel initiator for mobile to mobile packet flows, mobile to land line packet flows, and land line to mobile packet flows. Route optimization can also be provided in certain embodiments.

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 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。此外，每个机架可以具有一个或多个处理订户会话流量的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 are provided for recovering from an interruption in, or failure of, an L2TP tunnel connection, such that reconnection of the tunnel is not required. According to various embodiments, redundant storage 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 to elicit a response.
