PURPOSE: A hop pattern updating method using a preamble pattern in an FH(Frequency Hopping) system is provided to elastically and effectively perform a hopping frequency update for various jamming in order to stably transceive control information, and to maximize an ECCM(Electronic-Counter-Counter-Measure) function. CONSTITUTION: A system inputs an initial power for a hop update, and maintains an idle state. The system receives a control signal packet from an RAU(Radio Access Unit) in the idle state, and analyzes information, then maintains the idle state. A hop generator converts a PPF(Ping Pong Flag) toggle value in the idle state of an information analyzing process. The system checks whether a hop updating is completed.
