There is provided a method comprising: transmitting, by a user terminal, to a state server a request for state change information of a service provided by the user terminal; receiving, by the user terminal, an indication of said state change information from the state server; and using, by the user terminal, said received indication to determine whether or not to suppress a polling relating to said service of a master server.

Communication system

Circuit and method for controlling a high bridge circuit with increased efficiency is disclosed. Circuitry is provided outputting gating signals to a high side driver and a low side driver responsive to a time varying input signal. A frequency measurement circuit determines a high speed mode when the input signal is at a frequency above a threshold, and the gating signal to the high side driver is inhibited. When the input signal frequency is below the threshold, the low side driver and the high side driver gating signals switch alternately. In an exemplary implementation, the frequency measurement circuit is provided as two counters outputting signals to a decision circuit which controls the half bridge circuit. Methods are provided for efficiently providing gating signals to the drivers of a half bridge circuit based upon the frequency of the input signal.
