 Abstract

The paper presents the modeling of one GSM cell using the MOdeling Specification and Evaluation Language, MOSEL2. MOSEL2 is the new version of MOSEL which is developed at the university of Erlangen, Germany. In this regards, the frequency spectrum of GSM cell is divided into two layers (super and regular) according to the underlay-overlay principle. Based on this principle, the super frequencies have better C/I (carrier-to-interference) ratio than the regular frequencies and usually used near the base station, while the regular frequencies are used for the whole cell. In this paper, and based on the above assumptions, the queueing model of GSM systems is suggested and the numerical solution of this model is presented by MOSEL2. As a result of this, the critical performance measures are presented and discussed.
