Description
The rapid advancement in technologies employed in mobile
telecommunication industries has improved the sector over the years.
However, it has also introduced another problem of ensuring backwards
compatibility between newer and older generations. Furthermore, as the
technology evolved from the older generation to newer ones, configurable
parameters increased, making it more complex to manage manually during
installation. This situation worsens when the mobile network operator
integrates network elements from different Original Equipment Manufacturers
(OEMs). As a result, the Self-Organizing Network (SON) management system
was developed. However, with increasing data traffic supplemented by new
and developing technologies and correspondingly bigger networks, it is clear
that network operations must be redefined in order to ensure optimal
performance. For device installations, configurations, resetting network
settings, and general network administration, a manual configuration
technique necessitates specialized skills. This is a time-consuming and
expensive operation. In today’s wireless technology, using this strategy results
in poor network quality. As a result, the emergence of enhanced mobile
networks has brought attention to the need of automation. SON enables
operating effectiveness and next-generation simplified network monitoring for
a mobile wireless network by automating the process. As a result of the
introduction of SON in LTE, network performance is improved, end-user
Quality of Experience (QoE) is improved, and operational and capital
expenses are reduced (OPEX). This paper highlights the SON techniques in
the mobile wireless network and briefly describes SON architecture.
