  • Patent number: 8522315
    Abstract: 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.

  • Patent number: 8289936
    Abstract: 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.

  • Patent number: 7127428
    Abstract: 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.

  • Patent number: 6956871
    Abstract: 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.

  • Patent number: 6954793
    Abstract: 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).

  • Publication number: 20030206549
    Abstract: A method, apparatus and data structure are described which enables complete datagram reception by a plurality of clients using a UDP multicast transport mechanism, wherein missing packets are retransmitted from a server using either a multicast transport mechanism or a unicast connection, in response to receipt by the server of client request to retransmit. Data structure of packets includes a new sequence identifier field in the header for identification of proper packet position within a data stream.
