John Michael Cullen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Communications system with controlled selective measuring of traffic properties
    Patent number: 6339698
    Abstract: A communications system includes a plurality of functional elements and measures properties of the functional elements. A processing function element controls the measuring and receives data from the measuring step. Communications links the central processor with the measuring element and the processing element is arranged to selectively instruct the measuring element to transmit selected data to the processing element.
    Type: Grant

    Date of Patent: January 15, 2002
    Assignee: British Telecommunications public limited company
    Inventor: John Michael Cullen
  • Telecommunication network which transmits the state of an occurrence of a non-call related service request associated with a network termination
    Patent number: 6266535
    Abstract: A telecommunications network provides communications links between network terminations, and includes switches, two or more network terminations interconnectable by the switches to establish communications links between network terminations and a service control point for providing service to or for the network termination and/or the switches. The network determines the occurrence of a service request from a network termination and for the switches independent from a request for establishing a communications link between network terminations.

  • Communication system with traffic distribution over multiple paths
    Patent number: 5950135
    Abstract: A telecommunications network made up of a plurality of bearer links and a plurality of nodes, is disclosed. According to the present invention, at least some of the nodes have elements configurable to allow signals arriving over one link to be retransmitted over more than one link, and/or at least some of the nodes have elements configurable to allow signals arriving over different links to be combined for retransmission over a single link, thereby permitting traffic to be carried between the two end point nodes a plurality of routes simultaneously.

  • Method and apparatus for intranetwork communication
    Patent number: 5920565
    Abstract: A method and apparatus for controlling a communication system having functional elements that perform monitoring or control functions using data flow to and from control function elements is disclosed. The functional elements do not necessarily employ the same communication protocol as the elements with which they communicate. Accordingly, the intranetwork communications of the communication system are processed to provide appropriate conversion of intranetwork messages via an interface element.
