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： 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： A system and method are shown for offloading a computational service on a point-to-point connection. When a tunnel initiator network device, such as a Level 2 Tunneling Protocol Access Concentrator (LAC), detects a tunnel client network device, the LAC sets up a tunnel connection with a tunnel endpoint network device, such a Level 2 Tunneling Protocol Network Server (LNS). During a process of establishing a call session on the tunnel connection, the LAC sends its compression capabilities to the LNS. When the LNS detects that the LAC is capable of compressing tunnel packets, the LNS negotiates compression parameters with the tunnel client network device. Subsequently, the LNS transmits the negotiated compression parameters to the LAC that configures a compression engine based on the received compression parameters. Hereinafter, the tunnel client network device will send compressed tunnel packets to the LAC that will decompress the received tunnel packets prior to transmitting the tunnel packets to the LNS on the tunnel connections. Similarly, the LNS will send uncompressed tunnel packets on the tunnel connection to the LAC that will compress the received tunnel packets prior to transmitting the tunnel packets to the tunnel client network device.
摘要翻译：示出了用于在点对点连接上卸载计算服务的系统和方法。当诸如二级隧道协议接入集中器（LAC）的隧道发起者网络设备检测到隧道客户端网络设备时，LAC与隧道端点网络设备建立隧道连接，诸如2级隧道协议网络服务器 LNS）。在隧道连接建立呼叫会话的过程中，LAC向LNS发送压缩功能。当LNS检测到LAC能够压缩隧道数据包时，LNS与隧道客户端网络设备协商压缩参数。随后，LNS根据所接收的压缩参数将协商的压缩参数发送到配置压缩引擎的LAC。在下文中，隧道客户端网络设备将向LAC发送压缩的隧道分组，该隧道分组将在隧道连接上将隧道分组传输到LNS之前对接收到的隧道分组进行解压缩。类似地，LNS将在隧道连接上发送未压缩的隧道数据包到LAC，LAC将在将隧道数据包发送到隧道客户端网络设备之前对接收到的隧道数据包进行压缩。

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： 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 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.
