Abstract:
A method of synchronizing the timing of a base station transmitter of a network for a cell transmitting, repeatedly in response to associated clock timing information having a phase, on at least one frequency, information denoting an event, the timing of the even to occur nominally at a particular time as denoted by universal timing information that can be received within the cell, the method, comprising:repeatedly determining from a signal received from the transmitter by an associated clock when the event information was in fact transmitted;repeatedly determining an amount of timing error from the nominal time;processing according to a filtering algorithm the amount of the timing error; andaltering the phase of the associated clock timing information based on the processing according to the filtering algorithm to correct the amount of timing error,wherein the signal received from the base station transmitter by the associated clock has been transmitted from an antenna and received by a GSM.sub.-- receiver.
