Abstract: PURPOSE: A method for transmitting an asynchronous transfer mode(ATM) cell header is provided to request a cell header interleaving relating to connection when an error correction fails in a header error control(HEC), and if an error of the corresponding connection is not an existing traffic channel or a generic flow control(GFN), so as to efficiently control an error relating to a transmitted cell. CONSTITUTION: If a receiving side receives a cell transmitted from a transmitting side, the receiving side detects an error of the cell. If an error correction of the cell is possible, the receiving side performs the error correction relating to the cell. If the error correction fails, the receiving side requests an interleaving relating to a header of the cell to the transmitting side. When the error correction is performed, the receiving side decides whether the error correction is successful. If the error correction fails, the receiving side decides whether a problem is generated in a traffic control of the cell. If not, the receiving side requests the interleaving. If the problem is generated, the receiving side manages the amount of cell receptions and suppresses an abandon rate or a delay time of the cell within a setup value.
