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 network 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.

INTRODUCTION
The conventional GSM networks in Nigeria suffers from poor quality of service and congestion effects . Objective measurement in the context of quality of service in mobile cellular networks has presented a major challenge for both the stakeholders and end-users.
This is traced to the peculiarities associated with the QoS metrics. However, the distinguishing characteristics for networks QoS evaluation must tend towards two major ends: a credible and reliable assessment of the likelihood that users will find a particular service satisfactory.
The determination on how system performance could be changed when that assessment shows that users are not likely to be satisfied.
In recent past, approaches of proposed network quality of service metrics, took little cognizance the interests of the users of telecommunications services and the perspective of the experts who design, build, and operate the systems that deliver those services [2].
Wireless mobile Internet is migrating towards an integrated system of Internet and telecommunication technologies in order to fulfill the future requirements of GSM networks i.e ubiquitous communication with best service availability.
This demands a rapid progress in GSM networks and Internet technologies QoS analysis. Some suggests that Quality of Service should be based on reliability, availability, security, assurance, simplicity and flexibility of the network as criteria for judgment.
Others based their study on user’s satisfaction using coverage, call quality, promotions and offering of incentives and rewards, prices of services, billing etc. –J.D Power and Associates Survey in United Kingdom (2008).
