In this paper, we optimize the usage of both control and traffic channels of a CDMA system by switching the MAC states of a service. In particular, we find the optimal transition timers for a cdma2000 system supporting integrated voice and data traffic. This is achieved by optimizing a composite performance metric defined as a multi-objective function of channel utilization, waiting time and the saving in the signalling overhead. First, we try to characterize wireless data as a mix of of Poisson-distributed voice packets and Pareto-distributed data packets, and study the effect of the composition of the mix and the shape parameter of Pareto distribution on the system performance. Then we derive analytical expressions for the composite performance metric with a goal to obtain the optimal values of expiration timers at which the MAC states should be switched such that the system performance is maximized. Since a closed form solution could not be obtained due to the transcendental nature of the analytical expression, simulation experiments are conducted to confirm the analysis.
