PURPOSE: A method to gain the frame synchronous in mobile communication system is provided to reduce initial synchronous time. CONSTITUTION: A system includes the steps proving the compared dynamic threshold after collecting the transmitted signals, 2) finding a first perch channel and detecting the mask symbol of long signal, if proved, 3) finding a second perch channel and detecting the group identification code having correlation value and frame code after detecting the mask symbol of long code from transmitted signals, 3) detecting the long code having maximize correlation value.
