    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 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: 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: A high density network access server implements a tunneling protocol between a modem module and a route server module. PPP and routing control packets received from the PPP link are tunneled to the route server for processing. The IP data packet forwarding function for the network access server is distributed directly to the modem modules. The combination of distributed PPP processing and distributed IP data packet forwarding enables the capacity of the network access server to be scaled to orders of magnitude greater than previously known, to handle thousands or even tens of thousands of simultaneous data sessions.

    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.
