A Study of GSM Voice Traffic Using Measurement Performance Technique

Sahib Khan Ahmadzai | Omkar Manohar Ghag ^[5]

Abstract: This study investigates the measurement performance technique used to analyze GSM cellular voice traffic, employing the Erlang B formula in live networks under varying conditions. Voice traffic and congestion rates were collected from a range of cell configurations at peak periods. The analysis identified slight differences between measured traffic and calculated traffic based on the Erlang B formula. Data was extracted from a GSM network in Afghanistan for different busy hours and cells with diverse configurations. Metrics such as the total TCH Traffic, TCH Half rate traffic (TCHH), TCH Congestion, available TCH and TCH Availability were considered. These findings contribute significant insights into the effectiveness and accuracy of the Erlang B formula for traffic calculation in GSM voice networks and reveal potential variances when applied in actual network conditions. Further examinations are needed to refine the models, considering the slight differences encountered during the study.
