In this paper, we present an analytical traffic model for the Universal Mobile Telecommunication Systems (UMTS). In 3G networks we have dynamic capacity that depends on the interference levels in the covered area and the number of active users. This implies that the distance of the mobile user from the base station is also an important factor because of the signal fading. The first part of this paper is an algorithm written in c++ programming language that distributes users in different zones assuming that the cell area is virtually divided into Z zones depending on the number of users. The last part of this paper we build a mathematical model of a 3G cell using the above assumption , and to prove, that the product form holds in the case of two cells with uniform and non uniform traffic. By this result more complicated networks can be analyzed, to calculate the performance measures of the network.

Modeling, Specification & Evaluation Language (MOSEL), tool used for the performance and reliability modeling of communication systems, computers, and manufacturing systems, once the system is specified using this language. The modeling language is part of the evaluation environment. Once the system is specified using the language, the evaluation environment takes place by executing the performance analyses of the model, and calculating the steady state probabilities . After this stage, results can be collected in the result file or in graphics mode using the Intermediate Graphical Language (IGL), where the aim of this paper is to give an overview of mosel and to show a real example under windows platform.

Abstract The number of mobile service users has been tremendously increased during the last few years, and the types of mobile services are developed from pure voice to data and multimedia services, such as audio/video streaming, e-mail, file transfer, and web browsing. These services have quite different requirements for their quality. 3G WCDMA cellular mobile networks answer this growing demand for these wireless data services. Then it needs to provide a huge capacity and wide area of coverage with acceptable quality of service. Capacity and coverage in WCDMA networks planning are the important issues because they are dependent of each other and related to the services data rate. In this thesis the capacity and coverage of mixed rate services are derived and analyzed. The uplink Capacity Coverage Product (CCP) of mixed rate services is developed by two methods, and three scenarios are assumed. The first method is the exact solution and the second method is the approximate solution. Math lap computer programs are used to get results and curves. Then some parameters affecting the mixed rate CCP are studied and a comparison between the two methods is also performed.The application of CCP in dimensioning and planning of a single service and mixed rate services WCDMA network is presented. A comparison with the conventional planning method is performed.
