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.

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： 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： In one embodiment, an apparatus cascades groups of serialized data streams through devices, and performs operations based on information communicated therein. A received group of serialized data streams is aligned, but not framed, and forwarded to a next device (e.g., a next stage in a linear or tree cascaded formation of devices). Eliminating the framing and subsequent serialization operations performed on the received group of serialized data streams reduces the latency of communications through the cascaded devices, which can be significant when considered in relation to the high-speed communication rates. The received group of serialized data streams is also framed to create a sequence of data frames for processing (e.g., associative memory lookup operations, controlling multiplexing of received downstream serialized data streams, general or other processing) within the device.
摘要翻译：在一个实施例中，设备通过设备级联串联数据流组，并且基于在其中传达的信息执行操作。所接收的一组串行化数据流被对齐，但不被成帧，并被转发到下一个设备（例如，设备的线性或树形级联形成中的下一级）。消除对所接收的串行化数据流组执行的成帧和随后的串行化操作减少了通过级联设备的通信的延迟，当考虑高速通信速率时，这可能是重要的。接收到的串行数据流组也被成帧以创建用于处理（例如，关联存储器查找操作，控制所接收的下游串行化数据流的多路复用，通用或其它处理）的数据帧序列。

摘要： Tones that are generated by a telephone or PC (such as DTMF tones) and subject to loss or noise during generation or during transmission along a medium are detected and replaced with substantially noise-free and distortionless digital signals. In one embodiment, the replacement of the tones is done in a modem embodied in an Internet telephony Gateway/Terminal, such as in a network access server coupling a time division multiplexed telephone line to a packet-switched network. The replacement of the tones may also be performed in any suitable device that provides an interface between a time division multiplexed transmission medium and a packet switched data network, such as in the modems of a cellular telephone network to Internet network access server.

摘要： A network access server providing remote access to an IP network for a remote client initiates a PPP connection for a remote client quickly, and without requiring re-negotiation of Link Control Protocols and Network Control Protocols. The network access server has a PPP session with the remote client go dormant, for example when the user is a wireless user and goes out of range of a radio tower and associated base station. The network access server does not get rid of the PPP state for the dormant session, but rather switches that PPP state to a new session, such as when the client moves into range of a different radio tower and associated base station and initiates a new active session on the interface to the wireless network. The switching of PPP states may be within a single network access server, or from one network access server to another. This “context switching” of the active PPP session allows the mobile user to seamlessly move about the wireless network without having to re-negotiate Link Control Protocols and Network Control Protocols every time they move out of range of one radio tower and into range of another radio tower.
摘要翻译：为远程客户端提供远程访问IP网络的网络访问服务器可以快速启动远程客户端的PPP连接，而无需重新协商链路控制协议和网络控制协议。网络接入服务器与远程客户端进行PPP会话休眠，例如当用户是无线用户并超出无线电塔和相关基站的范围时。网络访问服务器不能摆脱休眠会话的PPP状态，而是将PPP状态切换到新会话，例如当客户端移动到不同无线电塔和相关联的基站的范围内并启动新的活动会话在无线网络的接口。 PPP状态的切换可以在单个网络接入服务器内，或者从一个网络接入服务器到另一个。有源PPP会话的这种“上下文切换”允许移动用户无缝地移动无线网络，而不必在每次移动超出一个无线电塔的范围并进入另一个无线电塔的范围时重新协商链路控制协议和网络控制协议无线电塔。

摘要： Two network entities allocate the performance of encryption and compression algorithms amongst each other in a controlled and coordinated manner so as to avoid unnecessary duplication of encryption and compression at different protocol layers and an associated waste of CPU power. For example, a first network entity performs both encryption and compression at the IP layer, and instructs the second network entity to disable PPP-layer encryption and compression. In a wireless networking example of the invention, the first network entity is a home agent (e.g., a router) for a wireless communications device and the second network entity is a foreign agent (e.g., a network access server) providing network access for the communications device. The foreign agent terminates a Point-to-Point Protocol (PPP) session with the communications device, but implements (or does not implement) PPP-layer compression and encryption algorithms under the supervision and control of the home agent.
摘要翻译：两个网络实体以受控和协调的方式分配加密和压缩算法的性能，以避免不同协议层的加密和压缩的不必要的重复以及CPU功率的相关浪费。例如，第一网络实体在IP层执行加密和压缩，并指示第二网络实体禁用PPP层加密和压缩。在本发明的无线网络示例中，第一网络实体是用于无线通信设备的归属代理（例如，路由器），并且第二网络实体是提供网络接入的外部代理（例如，网络接入服务器）通信设备。外部代理终止与通信设备的点对点协议（PPP）会话，但在归属代理的监督和控制下实现（或不实现）PPP层压缩和加密算法。

摘要： A mobile Internet Protocol service provider system implements home agent functionality in two separate devices. One device, the home registration agent, is devoted to registration of the mobile node and session control. The other device, the home tunneling agent, is devoted to tunneling and routing functions for the foreign agent. The home registration agent can be a general purpose computer. The home tunneling agent is preferably implemented in a robust routing device, such as an IP switch or router. Multiple home tunneling agents or home registration agents can be implemented in the respective devices as multiple instantiations of a home registration agent or home tunneling agent software program.Foreign agent functionality for mobile IP networking can also be split into separate devices. In a preferred embodiment, a foreign registration agent handles session control and registration traffic with the home registration agent, and a foreign tunneling agent provides packet capsulation/decapsulation and routing services for the mobile node and exchanging data traffic with the home tunneling agent.

摘要： In a Quality of Service system, segments in a TCP session are assigned a priority level. A segment may contain an acknowledgement and data. The system determines if network congestion is detected or anticipated in the segment's priority band or in a higher priority band. When the TCP segment arrives at a network point, the segment is split into an acknowledgement segment and a data segment. The acknowledgement segment is scheduled at a higher QoS priority than the data segment.
