    Abstract: PURPOSE: A 2-phase weighted process cell scheduling method in an ATM(Asynchronous Transfer Mode) network is provided to maintain the fairness of a cell service by using the scheduling of both a time stamp type and a frame type. CONSTITUTION: A weight value, a timer value, and a certain queue threshold value are set up in a plurality of channels. The minimum timer channel having the minimum timer value is retrieved among a plurality of channels. Cells of the minimum timer channel are transmitted, and a certain value is assigned to a timer value of the minimum timer channel. The maximum queue channel having the longest queue length is retrieved among a plurality of channels. Cells of the maximum queue channel are transmitted, a weight value of the maximum queue channel is decreased by 1, and a certain value is assigned to the timer value of the maximum queue channel.
