Real-time Admission Control and Revenue Optimization for Cellular DS-CDMA Networks

In this paper, we propose a real-time admission control mechanism in conjunction with revenue optimization for DS-CDMA network. For solving the optimization problem, iteration-based Lagrangean relaxation approach is applied by allocating a time budget. The achievement in terms of problem formulation and performance analysis is presented. Associated parameters considered are mean arrival rate, mean call holing time, and time budget. Computational experiments indicate that time budget is a key factor to affect the system loading, and small mean arrival rate is more significant than large mean arrival rate especially. Time budget and mean call holding time jointly affects the ratio of admit to existence. The analysis concludes that assigning time budget 6 seconds is proper value in real-time admission control.
