ABSTRACT
In this
research, enhancing mobile network portability for wireless communication
system providers in Nigeria is presented. Key Performance Indicators (KPIs) of
network providers in Nigeria were examined. Mobile network data for Aba, (Abia State), Umuahia, (Abia State), and Mbaise, (Imo
State) collected from Nigerian Communication Commission (NCC) was used for
the study. The two prominent network operators in
Nigeria namely Mobile Telecommunication Nigeria, (MTN) and Global Communication
Nigeria, (GLO NIG) were analyzed in the context of their Key
Performance Indicators data which Nigerian Communication Commission (NCC)
regulates. The collected data shows the non uniformity of the operators in
terms of Quality of Service (QoS) delivery to its customers. This was further validated by comparing the
NCC benchmark with the Key Performance Indicators of network providers
considered. The Key Performance Indicators (KPIs) considered in this research
were Call Drop Rate (CDR), Call Setup Success Rate (CSSR), Agent Utilization Rate
(AUR), Handover Success Rate (HSR), Awaiting Time (AWT) and Call Quality Factor
(CQF). The findings lead to a better method
of subscriber migration
in mobile cellular networks and
its implementation framework in
future mobile phones and devices. A Fuzzy-SIMULINK portability Suite for Mobile Number
Portability (MNP) network model was implemented. Consequently,
this research then developed a Java Visual Sim portability Suite for Mobile
Number Portability (MNP) while formulating a parametric SIM network algorithm. From
the results obtained, it was observed that taking an average of the MNP for the
various networks under study, MTN NG ranks better with an average score of 78%,
strongly followed by GLO NG with an MNP score of 77%. From the
study, it was also observed that none of the network operators reached the NCC
target for mobile number portability of 80% score for the considered KPI’s. But
in terms of customers satisfaction, call volume and service level, it was
observed that GLO NIG has the best network performance as compared to MTN
Nigeria. The research equally
observed that call drop rate experienced by some Network operators could be
attributed to low signal strength on the downlink or uplink, lack of best
server, congestion in neighbouring cells, and unsuccessful outgoing handover. The
research recommend that the regulators of these network operators must actively
encourage the use of improved MNP scheme to avoid subscriber exploitation while
compelling service providers to come up with innovative scheme that will
improve Quality of Service.
