Abstract

In this paper, performance evaluation of one UMTS cell is presented. The UMTS stands for Universal Mobile Telecommunication Systems, the third generation of mobile networks. The queuing model of one UMTS cell is suggested and solved for the first time using MOSEL-2 language, which is the new version of MOSEL, developed by the group of MOSEL in the University of Erlangen, Germany. The pre-processor rule of MOSEL-2 is used in this paper, which is useful to solve the model using both exponential and non-exponential distributions. The effect of important parameters on UMTS performance is studied in this analysis, such as the variability of service time, the availability of the codes and the effect of the arrival rate, l. It is shown that the mentioned parameters have a major effect on UMTS performance and should be taken into consideration by the network designers. Based on the above, critical performance measures such as blocking probability and utilization are found and discussed.
