1. A method of controlling a sleep mode in a portable terminal having a main controller and a sub-controller operating at low power, the method comprising:

  • detecting, by the sub-controller, a first sensor signal generated by a first sensor when the main controller is in the sleep mode;

    extracting a sensed pattern from the detected first sensor signal;

    determining whether the extracted sensed pattern is substantially identical with a preset wake-up pattern; and

    cancelling the sleep mode by waking-up the main controller when the extracted sensed pattern is substantially identical with the wake-up pattern.
