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： In one embodiment, a system including a memory capable of storing data and a processor is disclosed. The processor is configured for using the data such that the system can request from a source gateway subscription information related to a plurality of multicast video streams subscribed by the source gateway upon receiving a handoff request from a mobile device transitioning from a source region to a target region, wherein the handoff request contains information related to the source gateway. The processor is further configured for using the data such that the system can subscribe to at least a subset of the plurality of multicast video streams before the requested handoff is complete.

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： 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 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 marco base stations and other types of access technologies such as Wi-Fi.

摘要： In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

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.
