Global system for mobile communications (GSM) is a digital
cellular radio network that uses more advanced technology
and handles more subscribers than the analog cellular
network due to the use of Time Division Multiple Access to
divide the channel in time. It offers high quality voice
communication and low bandwidth (96 kb/sec) data connections
for fax and Short Message Service (SMS). Data connection
services like browsing, multimedia and e-mail demands on
mobile telephone have increased tremendously. Many people
have subscribed to GSM services due to the outlined features
and all these have led to congestion on the GSM network.
This is the main problem facing the GSM operators in the
quest to satisfy subscribers. This paper gives a brief
history of cellular networks, factors that led to the
congestion and an overview of the congestion and where they
occur on the GSM network. Some optimization models that can
be applied to minimize the congestion problem on the GSM
network in Nigeria are presented. These models are:
government and corporate organizations in partnership with
GSM operators use of dynamic half rate decoder, national
roaming agreement, regionalization and merging GSM networks.
Key words: Global system for mobile communications, operator,
subscriber, channels, roaming, congestion. |
