  • Patent number: 9172726
    Abstract: A method and apparatus are provided for allowing IP endpoints to communicate over a PSTN with improved signal quality. Watermarks are used in the handshaking between the end-points when a communication session is being established, the watermarks indicating that the endpoints are capable of VoIP. If the two end-points establish that they are each VoIP-capable then packet data is inserted into a TDM channel using a framing technique managed by the gateways, with the bearer data being native to the VoIP devices, avoiding the lossy conversion of packet-voice data to 64 kb/s PCM and back to packet data again, realizing that the other end-point will be able to decode the data. If an IP-enabled endpoint determines that the other endpoint is not IP-enabled, then the data is inserted into the TDM channel by the gateway after conversion to 64 kb/s PCM so that the resulting TDM stream remains compatible with the PSTN and non-IP endpoints.

  • Patent number: 8315951
    Abstract: A method and apparatus are provided for providing authentication of an e-commerce server to a user engaging in e-commerce transactions. When the user begins an e-commerce session, the e-commerce server requests an authentication token from an authentication proxy with which it has registered. If the authentication proxy recognizes the e-commerce server, the authentication proxy generates an authentication token in the form of a simple image, and sends the authentication token to the e-commerce server over a trusted path. The e-commerce server sends the authentication token to the user. The authentication proxy also sends a copy of the authentication token to the user over a second trusted path to a second device or application accessible by the user. The user can then see that the authentication token presented by the e-commerce server matches the authentication token presented by the authentication proxy.

  • Patent number: 7881199
    Abstract: A method is provided for ensuring that specific traffic flows are adequately prioritized in a public packet communication network even when the network is heavily congested. Per-flow QoS capability is added to VPN tunnels. Connection requests are routed through a specific port in an access provider's network to designated VPN gateway. Deep packet inspection is performed on traffic through the port in an attempt to determine whether the connection request was accepted. If the connection request was accepted, the traffic flows associated with that session may be given a specific priority of QoS level when transiting a packet access network.

  • Patent number: 7680922
    Abstract: A method and apparatus for assessing a communications' network adherence to Service Level Agreements (SLAs) is presented. The apparatus includes a arrival curve parameter derivation and arrival curve parameter reporting means. A arrival curve parameter generator may be implemented either in hardware for a predefined response in fitting arrival curves to cumulative content arrival variations, or in software for flexibility in the content traffic considered for assessment. The arrival curve generator may be associated with a physical port, a line card, or a network node. Arrival curve parameters defining arrival curves are employed by a Network Management System (NMS) in conjunction with communications network node and communications network service curves in performing SLA conformance assessments.

  • Patent number: 7675873
    Abstract: A system and method are provided for providing users of voice conferencing with indications of the quality perceived by other users of the voice conferencing system. A voice conferencing bridge measures the quality of the each user's channel, and provides real-time feedback to users whose channel quality is inadequate and that other users cannot hear them clearly. The feedback may be in the form of in-band or out-of-band signals, indicating for example that the user should speak louder, should mute while off-line, or warning the user that his or her channel may be muted automatically. The last option is particularly useful if a participant has temporarily left the conference and is playing music or hold tones while absent.

  • Publication number: 20090164654
    Abstract: A method and apparatus are provided for allowing one subscriber of an IPTV service to locate and pre-configure Internet-based IP radio channels of interest to others, and to invite the others to register for viewing the IP radio channels. The first subscriber browses the Internet for content of interest, invokes the necessary configuration steps required by that content site, and then invites others to register for the content. The IPTV network stores the location of the content and the required configurations for the invited users. When an invited user logs on to the IPTV network, the IPTV network presents the user with a list of pre-configured Internet streaming channels to which he or she has been invited by another subscriber. If the invited user accepts an invitation to a channel located by the other subscriber, then the channel is added to the list of channels accessible by the user, and can thereafter be accessed by that user without familiarity of use of or direct access to the Internet proper.

  • Patent number: 7323988
    Abstract: A system and method are provided for allowing users to verify the presence of personal items. RFID tags are attached to personal items, and the items are entered into a list. The user makes travel lists from the list of items. When traveling, the user queries the system to determine whether all personal items in the travel list are within range of the system. The system checks for the presence of the RFID tags associated with the items in the travel list. If any RFIDs are not present, the user is alerted. Optionally, the system updates the last known location of items whenever checking for the presence of personal items, so that if an item is not found the user can determine where the item was last known to have been.

  • Publication number: 20060168123
    Abstract: A system and method are provided for queuing and downloading content from a network. A user browses a network for content, and informs a scheduler of desired content and download parameters, such as a target end user device and conditions that are to be met before downloading occurs. The scheduler stores the requested content until the target end user device is available and the conditions are satisfied, at which point the content is downloaded to the target end user device. The invention allows a user to browse for content at one point in time and using one device, and to have the content downloaded at a later point in time and possibly to a different device. This allows, for example, the user to browse for content during high cost access times and to retrieve large files during low cost access times.
