GSM traffic measurement on loss routes / Azril Idris

The objective of this work is to monitor the performance of Global System for Mobile Communication (GSM) telephone network. The performance involve three main aspects that is the service performance, system capacity and the Grade of Service (GOS). This paper explains how to measure the GSM telephone traffic and how to analyze the measured traffic data. From the data, daily analysis is made where the peak value, peak day, lowest value and lowest day of the week is determined. The peak value of the week obtained from daily analysis is used to plot a graph of peak traffic vs week and the trend is monitored. Calculation is also made to determine the traffic offered. From the values, a graph of traffic vs days is plotted and traffic flow is monitored. Relatively simple programs has been written in BASIC computer language to solve the Erlang B equation. Probability of calls blocked obtained from the Erlang B equation can be converted into GOS by multiplying it with 100 %. The conversion is to determine the GOS that the customers received. Besides that, traffic is also monitored from 9:30 am - 18:30 pm to show that 11:00 am - 12:00 noon is the busiest hour. From this observation, further recommendations are made with other considerations in order to provide the best performance for the customers.
