  • Patent number: 7843932
    Abstract: Narrowband signaling from a transfer node for a call originating at an end office is received at a centralized control and signaling interworking function device in an asynchronous transfer mode switching network. The received narrowband signaling is converted to broadband signaling. The broadband signaling is provided to a plurality of trunk interworking function devices via the asynchronous transfer mode switching network, to establish a connection across the asynchronous transfer mode switching network, when the centralized control and signaling interworking function device and the plurality of trunk interworking function devices are determined to be members of a closed user group.

  • Patent number: 7830785
    Abstract: Disclosed herein are systems, methods, and computer readable media for modifying IP backbone link weights such that multicast traffic and unicast traffic will not travel on a same path between nodes. The method comprises assigning link weights to nodes within an IP backbone such that multicast forwarding paths and unicast forwarding paths are failure disjoint, and delivering undelivered multicast packets using IP unicast encapsulation to the loopback address of next hop router on a multicast tree upon link/interface failure.

  • Patent number: 7823681
    Abstract: An interlock system using biometrics scans to identify in real-time an individual who seeks to operate a mechanical device, such as an automobile. Biometrics features that uniquely identify an individual are selected. If a real-time biometrics scan of the individual does not match a stored image of an authorized operator, the interlock system will lock the mechanical device to prevent operation. The interlock system may be used in conjunction with a breath alcohol analyzer to determine impairment. If the biometrics testing indicates that the individual is required to be tested for impairment, the mechanical device will not operate until the testing is completed.

  • Patent number: 7817793
    Abstract: Communications are routed in a communications network based on a location of a requesting party. A communication from the requesting party is received. A location of the requesting party is determined using a geographic address which defines the smallest of two of a set of multiple geographic areas defined by multiple available geographic addresses for the location of the requesting party. A communications destination address for the communication is selected, from multiple possible communications destination addresses, based on the location of the requesting party. The communication is forwarded to the selected communications destination address.

  • Patent number: 7813349
    Abstract: Method and apparatus to establish a communication link over a high speed communications network. A unique predetermined address assigned to a switching and access node of each network node of the high speed communications network is examined. In addition, a service address associated with a request to establish a communication link is examined. The service address indicates at least one of a type of service being requested, a network service detail, and a name of a desired service provider. Thereafter, an end-to-end communication link is established between the calling party and a destination party by routing a connection request through plural switching nodes in accordance with the calling party address, an address associated with the destination party, and the service address.

  • Publication number: 20100242113
    Abstract: A method and system for detecting routing loops and time-to-live (TTL) expiry attacks in a telecommunications network are disclosed. The detection of routing loops and TTL expiry attacks can be achieved based on the comparison of TTL expiries occurring on two or more routers in the network. A quantity of TTL expiries associated with a router can be summed. Additionally, a quantity of TTL expiries associated with other routers that are operatively coupled to the router can be summed. A difference between the sums can be calculated and a determination of whether a routing loop exists can be made in response to the difference.

  • Patent number: 7796190
    Abstract: Disclosed herein are systems, methods, and computer readable-media for adaptive content rendition, the method comprising receiving media content for playback to a user, adapting the media content for playback on a first device in the user's first location, receiving a notification when the user changes to a second location, adapting the media content for playback on a second device in the second location, and transitioning media content playback from the first device to second device. One aspect conserves energy by optionally turning off the first device after transitioning to the second device. Another aspect includes playback devices that are “dumb devices” which receive media content already prepared for playback, “smart devices” which receive media content in a less than ready form and prepare the media content for playback, or hybrid smart and dumb devices. A single device may be substituted by a plurality of devices.

  • Publication number: 20100098084
    Abstract: Communications traffic in a network is addressed. An original signal comprising an embedded destination service address is receiving at an ingress capable network device of the network. A database server is queried to obtain an internal routing address corresponding to the embedded destination service address. A transit signal corresponding to the original signal and including at least the embedded destination service address is routed through the network to an egress capable network device of the network according to the internal routing address. The transit signal enables the egress capable network device to restore the embedded destination service address and to forward the transit signal from the network.

  • Patent number: 7701947
    Abstract: A network node sets up a virtual connection in a network based on a virtual connection request initiated from an access port different from a first location previously associated with an account of a user. The network node includes a receiver for receiving a signaling message from the access port requesting the virtual connection. The signaling message has at least one field modified to include an address of the access port. The network node further includes a profile database and a registration server. The profile database stores a service policy associated with the user account. The registration server stores an address of the first location associated with the user account as a default registration, determines whether the user is authorized to establish the virtual connection based on the service policy, and replaces the first location address with the access port address when the user is authorized.

  • Publication number: 20100057560
    Abstract: Systems and techniques for predicting customer response to content and selecting content for delivery to particular customers in accordance with the predictions. As information is delivered to and received from a plurality of customers over multiple communication channels, data streams representing communications between providers and customers are analyzed and selected data extracted therefrom. Linkages are created between data collected from the different channels and data are anonymized. The data are analyzed to create a customer response predictor for each customer that models customer behavior and predicts customer response to advertisements. As content, such as advertisements, are to be delivered to a destination, information from a predictor created using data collected from a customer associated with the destination is used to select appropriate content.

  • Publication number: 20100057575
    Abstract: Systems and techniques for detecting presentations of sponsored content and identifying persons bearing the content. A set of sponsored content items is identified for which a bearer presenting the content item in qualifying ways may receive payment, and a group of participating users is established, with information being stored for the users so as to allow for identification of a user presenting a content item in order to direct proper credit to the user making the presentation. A plurality of video feeds are identified and monitored and any video feed in which a sponsored logo appears is further examined to identify a bearer of the content item. Upon identification of the bearer, presentation of the content item is evaluated and appropriate payment is calculated. Details of content item presentations and payments may be stored in connection with users and evaluated to provide insight into the circumstances surrounding and influencing presentations.
