AN IMPROVED MODEL FOR KEY PERFORMANCE INDICATORS ANALYSIS FOR MOBILE NUMBER PORTABILITY SCHEME FOR GSM SUBSCRIBERS IN NIGERIA

ABSTRACT

In Nigeria today it been observed that when changing from one GSM network operators to the other, customers has to give up their old numbers and adopt a new one. As a result, they face switching costs associated with informing people about changing their number, printing new business cards, missing valuable calls from people that do not have the new number, etc. In this research the Key Performance Indicatiors (KPI) of network providers and the causes of poor quality service quality by GSM networrk operators in Nigeria were examined. The review findings  leads to a  novel  method  of  subscriber  authentication in mobile cellular networks and its implementation  framework  in  future  mobile phones and devices. Mobile Number portability (MNP) Java VSIM Suite was suggested to all mobile network operators and the migration of subscriber to adopt. Mobile Number Portability is a circuit-switch telecommunications network feature that enables end users to retain their telephone numbers when changing service providers, service types, and/or locations. A Fuzzy logic block set of MATLAB/Simulink and Java programming language with Netbeans 7.0 and XAMP Control panel were used in realizing Mobile Number portability (MNP) of different mobile operators. A set of benchmarks which are considered as crucial for deployment while taking cognizance of user’s requirements of mobile devices shows that in the KPI investigations for MTN, GLO, ETISALAT and AIRTEL Mobile operators are still yet to deliver a uniform and efficient QoS. Furthermore, the approach demonstrates the replaceability of the existing SIM card GSM architecture with an adequate trusted software module proposed to develop an improved model for MNP scheme for GSM subscribers in Nigeria using KPIs.
