1. A method for frequency scanning in a Digital Video Broadcasting-Handheld (DVB-H) receiving terminal, the method comprising the steps of:

  • obtaining cell information of each of a plurality of cells and DVB-H frequencies for each of the plurality of cells, each of the DVB-H frequencies having an intensity higher than a predetermined intensity;

    mapping the DVB-H frequencies to the corresponding cell information and storing the DVB-H frequencies mapped to the cell information in a table;

    detecting a current cell in which the DVB-H receiving terminal is located when there is a request for DVB-H frequency scanning;

    determining if the table includes information about the current cell;

    scanning the DVB-H frequency corresponding to the information about the current cell when the table includes the information about the current cell; and

    obtaining system information from a digital broadcasting signal input by using the scanned DVB-H frequency, when the scanned DVB-H frequency has an intensity higher than the predetermined intensity,wherein storing the DVB-H frequencies mapped to the cell information in the table comprises;

    counting a number of times each of the plurality of cells have been scanned; and

    mapping the number of times to the corresponding cell information.
