1. A method for controlling power supplied to an RF (Radio Frequency) receiver in a paging receiver, comprising the steps of:

  • a) pre-establishing a paging transmission time interval between all subsequent transmissions of paging data, said paging data comprising preamble data followed by batch data;

    b) synchronizing a paging system so that it transmits all said paging data at the pre-established paging transmission time intervals;

    c) supplying power to the RF receiver for a test time interval, said test time interval being long enough to allow the RF receiver to receive data from the paging system and to allow a determination to be made whether the received data is preamble data;

    d) synchronizing the paging receiver with the pre-established paging transmission time intervals of the paging system, when the received data is the preamble data; and

    e) supplying the power to the RF receiver at the pre-established paging transmission time intervals in order to receive the paging data, after the paging receiver has been synchronized with the paging system.
