Application of Load Control in 3G CDMA Networks for Improved System Level Modelling and Performance Analysis

In this paper we developed a system level model of a CDMA network based on the power control ability of the system. From the load control problem formulation a measure of the system performance in terms of the system outage probability was derived, which is based on the system load and the resource consumption of each service. By means of dynamic system simulations we also showed how well the system level model fits with the numerical results. The presented system level model can be used for efficient network wide studies. For example, the end-to-end performance of the overall system may be evaluated without going into a deep level of detail for the CDMA network. Moreover, accurate models of the system behaviour can be used to enhance the decision criteria for the inherent load control methods, like call admission control.
