    摘要: An apparatus and method of the present invention allows the digitally decoding of asynchronous communication signals and includes a sampling and storing circuit for sampling a digitally converted asynchronous communication signal and storing sampled signal values corresponding to negative edge signal values, positive edge signal values, and central signal values. A derivative calculating circuit is connected to the sampling of storing circuit for receiving at least negative edge signal values and positive edge signal values and calculating derivatives. A comparator circuit receives the calculated derivatives and compares the derivatives with the threshold based on the calculated negative derivative and produces negative output and positive output values used for determining a decoded output signal.

    摘要: Methods, systems, and apparatus can be used to provide call routing in converged networks. In various examples, a converged call routing system can be used determine routing information associated with an incoming connection request. Routing information can be based upon one or more of a current location of a communications device or a profile associated with a communications device.

    摘要: Methods, systems, and apparatus can be used to provide concurrent call handover in converged networks. In various examples, a concurrent call handover can operate to transfer multiple calls between domains when a mobile device has two open call instances. In some implementations, multiple public service identifiers can be assigned for the call instances.
