APPARATUS FOR JAMMING RADIO WAVES OF EACH FREQUENCY AND A METHOD THEREFOR, PARTICULARLY FOR ALLOWING A BASE STATION TO PREVENT DECIPHERING OF A TERMINAL BY INTERFERING WITH ONLY A BCCH PROVIDING BASE STATION INFORMATION TO THE TERMINAL

PURPOSE: An apparatus and method for jamming radio waves of each frequency are provided to cut off a paging operation of a terminal while preventing communication interruption of an adjacent area, and reduce power used for generating jamming radiowaves. CONSTITUTION: A frequency domain including a BCCH is obtained(S201). The BCCH is analyzed to obtain time information of the BCCH, a size value of a signal and base station information(S202). A controller stores the time information of the BCCH, the size value of a signal and the base station information, calculates the frequency domain/time/strength of a jamming signal based on the information, and transfers a control signal reflecting the calculation result to an RF transmitter/receiver(S203). The RF transmitter/receiver transmits a jamming signal by controlling an antenna according to the control signal of the controller(S204).
