An apparatus and method for receiving a quick paging message in a mobile station wherein a controller for synchronizing with a second clock in a predetermined time slot and transmitting a command for obtaining a synchronization at a frequency of receiving the quick paging message where the MS selects a clock having a first period as an operation clock under the second mode and under the first mode, selects a clock having a second period earlier than the first period; a dual phase-locked loop operating in response to the clock selected by the controller, for synchronizing with frequency in response to the command from the controller; a oscillator for oscillating at the synchronized frequency with the dual phase-locked loop; and a radio frequency part for receiving the quick paging message over a forward quick paging channel synchronously with the oscillating frequencies.

1. An apparatus for receiving a quick paging message in a mobile station (MS) operated with first and second modes where the first mode is to receive a quick paging message in a predetermined time slot, comprising:a controller for synchronizing with a second clock in the predetermined time slot and transmitting a command for obtaining a synchronization at a frequency of receiving the quick paging message; where the MS selects a first clock having a first period as an operating clock under the second mode, and selects the second clock having a second period earlier than the first period under the first mode; a dual phase-locked loop operated in response to the clock selected for synchronizing with frequency in response to the command from the controller; an oscillator for oscillating at the synchronized frequency with the dual phase-locked loop; and a radio frequency part for receiving the quick paging message over a forward quick paging channel synchronously with the synchronized frequency from the oscillator. 2. The apparatus as set forth in claim 1, wherein the controller selects the first clock as an operating clock if the reception of the quick paging message is completed.3. A method for receiving a quick paging message in a mobile station (MS) operated with first and second modes where the first mode is to receive a quick paging message in a predetermined time slot, comprising the steps of:selecting a clock having a second period earlier than a first period as an operating clock if it is the first mode of MS; and synchronizing with the clock having the selected second period and transmitting a command for receiving the quick paging message to a dual phase-locked loop at the predetermined time slot to be thereby locked in a frequency capable of receiving the quick paging message in response to the command. 4. The method as set forth in claim 3, further comprising the step of:selecting a clock having the first period as an operating clock if the reception of the quick paging message is completed.
