The present invention is an improved method and circuit for reducing the amount of time a mobile receiver spends in the active phase of a slot in a communications system utilizing a slotted paging mechanism. The invention allows the awake time to be configured for the minimum interval needed to demodulate the paging channel messages of interest. The invention includes a means to adjust the timing reference of the fingers to compensate for a sleep duration not an integral multiple of the PN sequence period, and a means to adjust the deinterleaver frame reference timing to compensate for a sleep duration not an integral multiple of the frame interval, and a means to initialize the frequency tracking, gain scaling, and DC bias loops, if any, of the analog receiver chain to minimize the time needed to re-lock these loops.
