ABSTRACT
The adoption of the GSM system of communication in Nigeria is a long
anticipated development expected in the telecommunication sector in Nigeria. It
is expected that its introduction will bring about effective telecommunication
services that will support good speech quality, roaming, spectral efficiency and
minimized crosstalk just to mention a few items that will bring about effective
communication.
The objective of this project is to study the congestion problems in GSM
network in Nigeria. This is done using the various KPIs (Key performance
Indicators) in GSM which include CSSR (call setup success rate), CDR (call
drop rate) TCH assign failure rate (Traffic channel) etc.
BS (Base stations) will be studies and the data obtained will be used to
calculate the congestion rate. As it is mostly seen, it is the TCH assign failure
and SDCCH (Stand alone channel) assign failure that results into high rate of
call drops which in turn brings about very low call setup success rate (CSSR).
However, GSM in Nigeria has numerous problems hindering its proper
functioning but the most alarming of it all is the congestion problem and in
this project, that is what will be thoroughly analysed.
