The random access technique has a bigger influence to the performance optimization of CDMA2000 data traffic. A CDMA2000 random access technique based on self-similar model and its performance analysis are put forward in this paper. The simulation results indicate that the access performance of CDMA2000 data traffic based on self-similar model is attenuated by power law, related to such parameters as fractal coefficient H and network load G. The CDMA2000 fractal window random access protocol (FWRAP) is put forward and it can improve the access performance of CDMA2000 data traffic distinctly.
