摘要： Systems and methods are provided that allow inter-working between communication networks for the delivery of service to mobile nodes. A gateway is provided that communicates with a femto cell to extend service to an area that otherwise does not receive coverage from a service provider. The femto cell is a small scale base station used to provide coverage over a small area (such as a home or business), and connect to a home or enterprise network. The femto cell provides service for a mobile node and a gateway permits communication over a broadband network. The gateway integrates the mobile nodes connecting via a femto cell into the service provider's network. The gateway also allows provisioning of services and applications, control of service levels, and provides seamless handoffs to macro base stations and other types of access technologies such as Wi-Fi.

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.

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 hash so that different 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： 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 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 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 primary LNS, a peer LNS and a LAC are coupled to each other via a network A CPE is coupled to the LAC. A first tunnel is established between the CPE and the LAC using the network and information is transmitted through the first tunnel. A determination is made as to whether the primary LNS is overloaded or inoperative. State information is offloaded from the primary LNS to the peer LNS. If the primary LNS is inoperative or overloaded, a second tunnel is established from the CPE to the peer LNS using the state information. Information is transmitted though the second tunnel.
