Abstract
This paper presents a case study about the evaluation and optimisation of GSM
network in Jenien City, Palestine. Two approaches are used to evaluate the network performance,
namely: key performance indicators (KPIs) and drive test. The initial evaluation of the network
showed that about 0.76% of the initiated connections are dropped. In addition, about 7.76% of
the collected samples from the drive test lie in level 4 which is the worst level in terms of signal
quality and signal strength. Moreover, only 65.5% of the collected samples lie in level 1 which is
the best level in terms of signal quality and strength. A new traffic channel (TCH) and broadcast
control channel (BCCH) frequency plans are proposed to decrease TCH drop rate, reduce
interference level and boost signal quality. The proposed plans are implemented into the network.
Two kinds of optimisation procedures are adopted. The first one is manual optimisation while
the second one is by using specific optimisation tools. According to the comparative study, we
carried-out between the performance of the network before and after optimisation, the average
TCH drop rate is reduced from 0.76% to 0.62%. In addition, the percentage of samples in level 1
is increased from 65.5% to 76.8% while the percentage of samples in level 4 is decreased from
7.76% to 5.16%.
