Description	This paper deals with a speech quality assessment, especially with non-intrusive methods which are suitable for speech quality evaluation in realtime communication. The first part contains introduction to models of objective speech quality assessment based on evaluation of signals in time-frequency domain and afterwards a non-intrusive approach, which is known as E-model, is explained. The main contribution of this paper lies in proposal of a simplified E-model and its practical implementation into the Monitoring module in BESIP project. Next part deals with an impact of atmospheric conditions on the speech quality in the GSM using PESQ approach. Results from the MOS assessments based on long term measurements are reported, and an analysis of the obtained data is presented with outcomes from experiments which were performed in VSB-Technical University of Ostrava.
