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： Multiple home agents for a home agent service provider network are implemented in a single computing platform in software as multiple virtual home agents. Each home agent is assigned or dedicated to a single virtual private network. Any number of home agents can be realized in the computing platform by multiple instantiations of a home agent program or code, and by providing unique IP addresses for each instantiation. Each home agent runs independently, and is independently configured and managed by the subscriber of the virtual private network service, freeing the service provider of having to manage and supervise low level processing tasks and customization features that the subscribers may want. In a representative embodiment, the computing platform comprises a router having a general purpose-computing platform.

摘要： A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number. The authentication server sends an access-accept packet to the home agent in the event that the device is authorized to receive the IP packet, in which case the access-accept packet includes the identification information. The home agent uses the identification number to locate, page and automatically connect the wireless device to the IP network via an InterWorking Unit (IWU) configured as a IP network access server.
摘要翻译：当来自远程用户的因特网协议（IP）分组通过IP网络发送到设备时，找到移动无线通信设备的方法。移动设备不必向IP网络注册，以便接收IP。该方法包括以下步骤：在与无线通信网络相关联的归属代理处接收IP分组。 IP分组包括分配给设备的IP地址。如果移动设备没有当前的移动性绑定记录，则代理丢弃该分组，归属代理将包含该IP地址的接入请求分组发送到认证服务器。认证服务器（例如，RADIUS服务器）维护将设备的IP地址映射到与设备唯一相关联的标识号码（例如设备的国际移动订户身份号码）的表格。在设备被授权接收IP分组的情况下，认证服务器向归属代理发送接入接受分组，在这种情况下，接入分组包括标识信息。归属代理使用识别号码通过配置为IP网络接入服务器的互通单元（IWU）来定位，寻呼和自动将无线设备连接到IP网络。

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： 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 typical remote access application, such as access from the home to a packet-switched high speed network such as the Internet, the low-speed dial up connection to a network access is the main bottleneck in terms of the bandwidth and efficiency of transfer of data across the network access server. The present invention increases throughput through the network access server by identifying and dropping redundant, e.g., retransmitted, packets en route from the LAN or WAN to the remote terminal, thereby preserving precious bandwidth.

摘要： An election protocol or method is described for use in Internet Telephony, in which a gatekeeper is elected to serve as an active gatekeeper. The group of gatekeepers elect one gatekeeper in a zone to act as a primary gatekeeper that responds to gatekeeper request messages by broadcasting active gatekeeper claim messages that contain a unique gatekeeper priority value for the gatekeeper. The gatekeepers compare the received gatekeeper priority value with their own gatekeeper priority value and either broadcast another active gatekeeper claim message (if they are higher ranked) or do not broadcast another active gatekeeper claim message (if they are lower ranked). This process sorts the gatekeepers into a hierarchy with the highest ranked gatekeeper designated to respond to gatekeeper request messages. The other gatekeepers stand by in an idle mode and do not respond to gatekeeper requests. The other gatekeepers are ranked in priority in accordance with a gatekeeper priority value assigned to each gatekeeper. If the primary gatekeeper should go down (for example, due to either a graceful shutdown by a system administrator or due to a machine failure), a new gatekeeper is promoted to act as the primary gatekeeper based on the ranking of the gatekeepers, or the remaining gatekeepers can go through the iterative election process again.
摘要翻译：描述了在互联网电话中使用的选举协议或方法，其中选通守门员作为主动看门人。守门员组在一个区域中选出一名守门员，作为主要守门员，通过广播包含守门人唯一的守门人优先级值的主动守门人声明消息来响应关守请求消息。守门人将接收到的守门人优先级值与其自己的守门人优先级值进行比较，并且广播另一个主动看门人声明消息（如果它们排名较高），或者不广播另一个主动看门人声明消息（如果它们的排名较低）。该过程将守门人排序为具有指定为对守门员请求消息进行响应的排名最高的守门员的层次结构。其他看门人处于空闲模式，不响应守门人的请求。根据分配给每个守门员的守门人优先级值，其他看门人被优先排列。如果主要的守门员应该下台（例如，由于系统管理员的正常关机或由于机器故障而导致的），新的守门员被提升为基于守门人排名的主要守门人，或者剩下的看门人可以再次通过迭代选举过程。
