A method for scheduling a plurality of cells of N number of prioritized queues in a node of an ATM network is provided, wherein each prioritized queue has a static priority different from priorities of other queues. In response to receipt of a cell having a jth static priority, the cell is held for a holding time so that the cell turns to be an eligible cell for transmission. Meanwhile, an empty flag EFj '0' or '1' is generated on a time slot basis, wherein the empty flag EFj '0' or '1' represents whether or not there exists the eligible cell for transmission in the corresponding jth prioritized queue; and the jth prioritized queue is switched to a higher prioritized switch in a jth prioritized switch based on the empty flag EFj, wherein the jth prioritized switch has a jth and a lower input terminals, which are connected to the jth prioritized queue and the lower prioritized switch, respectively, and an output terminal, which is connected to the higher prioritized switch.
