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： 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： 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 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： Methods and systems are disclosed that provide accounting in an access gateway of a communication network. Logic can be implemented in an access gateway to provide accounting in an access gateway when the data is tunneled or encapsulated by a protocol when passing through the access gateway. The access gateway can perform inspections on the data to determine what portions of the data are user payload data and be included in a count and what portions of the data can be ignored, such as control packets and overhead information on the packet. The logic can also be deployed in next generation networks, such as long-term evolution, to provide accounting at the access gateway in some situations.

摘要： A method for switching between a first network element and a second network element, the first and second network elements each connected to a first network and a second network. The method may be carried out by configuring the first network element and the second network element to recognize the same data from the second network. Next, data may be readdressed so that it may be recognized by both network elements. After readdressed data are sent to the first network element and the second network element, the first network element may be disconnected from the first network and the second network element may be connected to the first network. Data may be forwarded from the second network to the first network with little or no loss during the switchover.

摘要： Systems and methods for improved inter-technology handovers between wireless networks are disclosed, in which a source radio access network operates on a first technology and a target radio access network operates on a second technology, and both radio access networks are managed at a single packet serving gateway. A foreign agent receives a mobile subscriber identifier during a handover of a mobile device from the source radio access network to the target radio access network and sends the mobile subscriber identifier to the packet serving gateway, and the packet serving gateway locates at least one process instance running on the packet serving gateway that is routing existing packet flows to the mobile device based on the mobile subscriber identifier. The packet serving gateway then transfers control of the at least one process to a control process.

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.
