An asynchronous transfer mode (&ldquo;ATM&rdquo;) cell transfer system in a wireless communication system provides quality classes that correspond to the amount of cell transfer delay allowed. Cells are classified according to a quality class and stored in buffers. The cells are read starting from the buffer for the quality class with the highest priority, and successively from buffers for quality classes of lower priority. Alternatively, if there is room in the output interval of cells of a higher priority quality class, cells of a lower quality class are inserted among these cells.
