Optimization Of Transmission Channel In A Gsm Telecommunications Network
Résumé: We treat through this dissertation the problem of channel optimization in 2G GSM network in M’Sila city. This dissertation is a combination of theoretical study and practical activities which are carried out on site. The objective behind this study was made in order to understand how to optimize a cellular network by taking into account different parameters that come into play in the optimization of this specific network. At the beginning, this dissertation gives a brief description of the characteristics of the GSM network, from the point of view of constitution, operation and propagation of radio waves. After that, the cellular concept and the KPIs, which are key factors in the optimization of a cellular network, have been also discussed. In collaboration with ATM Mobilis maintenance team, we propose an optimization procedure by augmenting E1 in order to overcome the degradation in the performance of GSM network, the bad quality of services (calls set-up problems, calls cuts, … etc) in one of the biggest streets in M’Sila city. In doing that, we used the WEBLCT software developed by Huawei. Obtained results show the efficiency of the proposed procedure and the quality of services is remarkably enhanced.
