Abstract: A wireless User Equipment (UE) delivers a priority communication service. In the UE, circuitry correlates a network Identifier (ID) for a wireless communication network with an instruction for the priority communication service. The circuitry identifies a user request for the priority communication service when the wireless UE is wirelessly attached to the wireless communication network. In response, the circuitry responsively identifies the instruction based on the correlation with the network ID. The circuitry exchanges network signaling with a radio based on the instruction and exchanges user data with the radio responsive to the exchange of the network signaling. The radio exchanges the network signaling and the user data with the UE circuitry and wirelessly exchanges the network signaling and the user data with the wireless communication network. The instruction may direct the circuitry to use an encoded public Uniform Resource Identifier (URI) to identify the UE to the wireless communication network.

Abstract: A driver circuit includes a first deglitcher circuit that delays a rising edge or a falling edge of an input signal according to a mode control signal and supplies a first output signal. A second deglitcher circuit receives the first output signal and delays either a rising edge or a falling edge of the first output signal by a second delay according to the mode control signal and supplies a second output signal. Logic gates combine the first and second output signals to supply gate control signals for output transistors to drive the driver circuit output. A sum of the first delay and the second delay determines the total deglitch time defining a pulse width of pulses that are suppressed by the driver circuit and the second delay determines a non-overlap time. The non-overlap time overlaps in time with the total deglitch time.
