Efficient traffic management for reverse traffic channels in high-speed CDMA systems

Abstract

We point out the unstable operation of reverse traffic management in the cdma2000 I xEV-DO system, and propose a new rate control scheme that controls the reverse traffic load more precisely. The proposed scheme is modeled as a multidimensional Markov process and compared with the conventional scheme. The analysis results show that the proposed rate control scheme has a lower overload probability and higher reverse link throughput than the conventional one.
