    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 for providing a handoff between technologies are disclosed. An intra-technology handoff occurs where the same integrated chassis handles the session for the different access technologies. In an intra-technology handoff, the same IP address and the session can be maintained through the handoff. The mobile node can undergo a handoff without issuing a registration request in some embodiments. An inter-technology handoff occurs from one integrated chassis to another integrated chassis. The integrated chassis can preserve session and context information in a session manager and in a handoff from one access technology to another the same session manager can be chosen with the session and context information remaining intact even though the access technology has changed. The integrated chassis can provide an access technology handoff where the core network does not notice any change and applications running on or delivered to the mobile node are not effected.

    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： Systems and methods for caching information related to access rights are provided. The access rights may be rules stored in an access control list. The cache may include packet parameters against which packets in a data flow are matched to determine if a match is possible from the cache. If a match is possible, a corresponding rule is applied to the packet. If a match is not found in the cache, the access control list may be searched for a corresponding rule. The rule from the access control list may be populated into the cache when a match is found in the access control list.

    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.
