Global System for Mobile Communication (GSM) network performance and QoS evaluation is an important requirement for MNPs operation. It directly impacts revenue generation and customer satisfaction. (Sireesha, Varadarajan, Vivek & Naresh). QoS mechanism controls the performance, reliability and usability of a telecommunications service. Many factors affect the QoS of a mobile network. There are standard metrics of QoS to the user that can be measured to rate the QoS. These metrics includes the coverage, accessibility, and the audio quality. In coverage the strength of the signal is measured using test equipment and this can be used to estimate the size of the cell. Accessibility is about determining the ability of the network to handle successful calls from mobile-to-fixed networks and from mobile-to-mobile networks. The audio quality measurement involves monitoring the clarity of a successful call for a period of time for the communication channel for the purpose of this research caller ring tone is considered. All these indicators are used by the telecommunications industry to rate the quality of service of a network. Consequently, immense effort is made by most MNPs to monitor their respective networks and maintain accurate status of its quality. This status, along with new traffic demand data is used by these operators to improve their network and adjust its operation.
Due to the high demand for GSM services, there has been a decline in the QoS experienced by most end users (Amaldi, Capone & Malucelli, 2008). This has resulted in both external and internal interest in monitoring the level of QoS maintained by most MNPs (Carvalho de Gouveia & Magedanz, 2000). By external, reference is made to independent bodies like the Nigerian Communications Commissions (NCC), and other research interests, apart from the Mobile Network Providers themselves (Internal). However, to measure QoS, it has been the practice to depend solely on data hosted and provided by the MNPs. These data are most often unavailable to the public, except through legal permission or some cooperation. Also, fidelity and integrity of such data remain unguaranteed. Therefore, external measurement of QoS status remains a challenge.
Consequently, recent trends have sought new methods to measure QoS independent of the MNP data. These have been used in different reports, and have formed a recent area of research. There are several KPIs used for measuring QoS such as CST, Call Completion Rate (CCR), Call Drop Rate (CDR), Call Handover Success Rate (CHSR) and Standalone Dedicated Control Channel (SDCCH), but focus here is on the use of CST and MSE for QoS estimation (Chunjie, 2008)
Recently, many people have become "citizens" of Internet or Web-enabled social communities, and use their mobile devices to upload data, thus having the ability to act as sensors. The term citizen-sensor network refers to an interconnected network of people who actively observe, report, collect, analyze, and disseminate information via text, audio, or video messages (Purohit, H. & Sheth) A. Hence, in this work, we use Citizen sensing technique in estimating the QoS of MNPs from caller ring tone in GSM.
