1. A method for controlling a picture-taking function of a mobile terminal in a picture-taking restricted area by using a signal generator, the method comprising the steps of:

  • generating, by the signal generator, a frequency signal on a specific wireless channel being currently unused for communication, and having high Received Signal Strength Indication (RSSI) and low pilot power/total received power (Ec/Io), the frequency signal being at a signal strength at least above a specific signal strength detectable in the restricted area;

    detecting, by the mobile terminal, the frequency signal;

    determining whether the detected frequency signal has a detected strength greater than a predetermined threshold; and

    deactivating the picture-taking function when a user of the mobile terminal selects the picture-taking function and the detected strength is greater than the predetermined threshold.
