摘要： An operator of a network (20) dynamically establishes a business relationship with a Billing Agent (26) to enable the network operator to receive reimbursement for access charges incurred by one or more users (121, 122 and 123). To establish such a relationship, the network operator first opens a communications channel to the Billing Agent after which the network operator and Billing Agent verify each other. Following verification, the network operator communicates proposed business terms and conditions, including access charges, to the Billing Agent. In response, the Billing Agent sends to the network operator an acceptance of business terms acceptable to the Billing Agent. After reaching agreement on the terms and conditions, the Billing Agent and network operator will each digitally acknowledge a formal agreement that embodies the agreed upon terms.

摘要： The invention herein provides an apparatus and a method for automatically configuring an IEEE 802.1x client terminal to provide limited access in a WLAN environment, specifically utilizing the access point to filter traffic associated with the limited access so as to redirect the client terminal's HTTP request to a designated local web server. The web server responds to the client terminal by requesting information required to establish an authorized communication. Thereafter the client terminal provides information required to establish an authorized communication. In the course of the communication the web server sends information such as transmission rates, new user account creation information, authentication method selection, and access user terms and conditions of acceptance, all typically required to establish an authorized access. The client responds with information, required to establish an authorized communication.
摘要翻译：本发明提供了一种用于自动配置IEEE 802.1x客户终端以在WLAN环境中提供有限接入的装置和方法，具体地利用接入点来过滤与有限接入相关联的业务，从而将客户终端的HTTP请求重定向到指定的本地Web服务器。 Web服务器通过请求建立授权通信所需的信息来响应客户终端。此后，客户终端提供建立授权通信所需的信息。在通信过程中，网络服务器发送诸如传输速率，新用户帐户创建信息，认证方法选择以及接入用户条款和接受条件等信息，这些信息通常需要建立授权访问。客户端响应建立授权通信所需的信息。

摘要： A user (121, 122) can gain access to a Local Area Network (LAN) (20) on a fee basis without the risk of having to transmit an un-encrypted PIN at upon initial access. The user initially sends a request to the LAN identifying a Billing Agent (26) that maintains an account associated with the user for payment of LAN access charges. In practice, the account can take the form of a pre-paid account identified only by a PIN known to the user. After the user has identified the Billing Agent, the LAN queries the Billing Agent for its digital certificate, which the LAN forwards to the user. The user utilizes the certificate to encrypt a PIN for transmission via the LAN to the Billing Agent for authentication. Upon successful authentication, the Billing Agent authorizes the LAN to grant access to the user, thus allowing the user to obtain a connection via the LAN to a private network (14) or a public network (16).
摘要翻译：用户（12 1，12 2）可以以费用方式获得对局域网（LAN）（20）的访问，而不必发送un 加密PIN在初次访问时。用户最初向LAN识别出一个账单代理（26）的请求，该计费代理（26）维护与该用户相关联的帐户以支付LAN访问费用。实际上，该帐户可以采用仅由用户熟知的PIN识别的预付费帐户的形式。在用户识别出计费代理之后，LAN会向计费代理查询其数字证书，LAN将转发给用户。用户利用证书加密PIN，以便经由LAN传送到计费代理进行认证。在成功认证后，计费代理授权LAN授予对用户的访问，从而允许用户通过LAN获得到专用网络（14）或公共网络（16）的连接。

摘要： A public wireless LAN permits receipt of non-authentication traffic, such as access information requests, from a mobile wireless communications device prior to device authentication by partially opening a controlled port within an access point. The wireless LAN re-directs such non-authentication traffic received at the AP from the mobile wireless communications to a local web server. The local web server provides reply to the mobile wireless communications device, enabling a determination by the device whether or not to request access. The device seeks access by way of an access request received at the AP. In response, the AP re-directs the access request through an uncontrolled port in the AP to an access server that authenticates device. Upon successful device authentication, the AP fully opens its controlled port to permit the exchange of traffic through that port with the mobile wireless communications device.
摘要翻译：在设备认证之前，公共无线LAN允许从移动无线通信设备接收诸如接入信息请求的非认证业务，部分地打开接入点内的受控端口。无线LAN将从AP接收到的这种非认证流量从移动无线通信重新引导到本地Web服务器。本地web服务器提供对移动无线通信设备的回复，使得设备能够确定是否请求访问。该设备通过在AP接收到的接入请求来寻求接入。作为响应，AP通过AP中的非受控端口将访问请求重定向到认证设备的访问服务器。在成功的设备认证后，AP完全打开其受控端口，以允许通过该端口与移动无线通信设备交换流量。

摘要： Disclosed is a method and apparatus for reducing the audio-visual synchronization problems (e.g.—“lip sync” problems) in corresponding audio and video streams by adapting a statistical distribution of temporal errors to create a new statistical distribution of temporal errors. The new statistical distribution of temporal errors being substantially within an acceptable synchronization tolerance window which is less offensive to a viewer/listener.
