PURPOSE: An interleaving method of an ATM cell in a wireless network is provided to variably control block sizes for being interleaved according to traffic kinds, and to interleave traffics. CONSTITUTION: A system sets up many block sizes of ATM cells for being interleaved(S101). The system decides whether a traffic of a waiting line for being interleaved is a loss sensitive traffic(S102). If so, the system performs an interleaving of the waiting line as an optimum fixed block size(S103). If the traffic of the waiting line is not a loss sensitive traffic, the system decides whether the traffic of the waiting line is a delay sensitive traffic, or decides whether the traffic of the waiting line is a traffic mixed the delay sensitive traffic and the loss sensitive traffic(S104). If so, the system predicts entire transmission delay time after cells of the waiting line are transmitted through a satellite network(S105). The system decides whether the transmission delay time is larger than a pre-set reference transmission delay time(S106). If not, the system performs an interleaving of an optional one block size according to a traffic capacity of the waiting line(S107). The interleaved traffic is transmitted to a terrestrial network through a satellite channel(S108). If the transmission delay time is larger than the pre-set reference transmission delay time, the system reduces block sizes of an interleaver(S109). Therefore, a cell waste rate caused by a limit excess of a transmission delay is minimized.
