This paper evaluated subscribers’ opinion on the Quality of Service (QoS) of GSM in Edo State, Nigeria. Four major GSM operators were used for the analysis. Data were generated through questionnaire administration. Information from respondents was analysed using descriptive analysis. The results of the analysis showed that the GSM respondents were not satisfied with the QoS provided by the network operators. The implication of this is that lack of attention to the improvement of QoS by GSM service providers would significantly decrease service use by subscribers in the chosen demographic region. The paper hence, aimed at identifying QoS problems in the selected region and proffering solutions to identified problems.

Unfortunately for cellular network service providers, loyalty is a rare trait among customers when it comes to choosing a particular mobile cellular system provider. Despite the huge financial commitment by companies into their respective communication technologies, users ultimately make decisions based on their perceived quality of service (QoS). It is the researcher's intention to identify the factors affecting the Quality of Service of cellular mobile network providers in Nigeria and put their effect in quantifiable terms. This study span for four years [2010-2014] and four leading telecommunication firms were selected to represent the entire telecommunication industry. These firms include MTN-Nigeria, Globacom, Etisalat and Airtel. The primary source of data used in this research work was questionnaire while the secondary source of data include data from; Nigeria communication commission(NCC), the above mentioned four communication firms as well as data from the researchers in related topical issues. The main quantitative approach used was regression analysis and for the easy of handling the volume of data, the use of statistical package for social sciences [SPSS] software was used. It was discovered that six factors affect the quality of service of cellular mobile network: Network coverage/ Availability of service(X 5) , Call quality(X 3) , Price of service (X 4) , Customer care(X 2) , Diversity of bundle option of service (X 1) and Promotion/Offering of Incentive(X 6). A predictive model was derived as : Y = 3.731+0.565X 5 + 0.440X 3 + 0.221X 2 + 0.189X 4 + 0.165X 1 + 0.097X 6
Quality of Service (QoS) and Quality of end-user Experience (QoE) are the two major techniques used for judging the performance of GSM services. While the former is adjudged by service providers, the latter is determined by reactions from end-users (subscribers). Assessment of GSM services from service providers' perspective is usually based on some Key Performance Indicators (KPIs). This paper utilize the five major KPIs (CCSF, TCH-CR, CSSR, DCR, HOSR) to assess the GSM QoS provided by MTN, Nigeria to cover Eagle Square Abuja before, during and after PDP presidential primary election. The results show that the KPIs deviate from the recommended values both during the event and non-event period thus the QoS requires an uncompromising improvements inorder to curtail further degradation in the services derived by the rapidly increasing subscribers' rate..
Network performance and quality of service evaluation of GSM Providers in Nigeria is presented in this paper.. The study used Lagos State of Nigeria as a case study in which three major towns – Ikoyi, Abule-Egba and Agege were covered. Since the commencement of GSM services in the country, the quality of service (QoS) being delivered by the four major Operators-MTN, GLO, Etisalat and Airtel, has been an issue of concern both to the subscribers and the national regulatory body. For this reason a study on the performance of these Operators in terms of service delivery is relevant. To achieve this, Radio Frequency (RF) measurements were made using the standard drive test method. Data collected were evaluated using QoS metrics as the key performance indicators (KPI) for determining the performance of each of the network provider. Using call drop rate (CDR), one of the performance indicators, it was observed that Etisalat had the least value of 0.6% of all the calls initiated during the test.
Enhanced Quality of Service (QoS) and satisfaction of mobile phone user are major concerns of a service provider. In order to manage network efficiently and to provide enhanced end – to – end Quality of Experience (QoE), operator is expected to measure and analyze QoS from various perspectives and at different relevant points of network. The scope of this paper is measurement and statistically analysis of QoS of mobile networks from end user perspective in Afghanistan. The study is based on primary data collected on random basis from 1,515 mobile phone users of five cellular operators. The paper furthermore proposes adequate technical solutions to mobile operators in order to address existing challenges in the area of QoS and to remain competitive in the market. Based on the result of processed data, considering geographical locations, population and telecom regulations of the government, authors recommend deployment of small cells (SCs), increasing number of regular performance tests, optimal placement of base stations, increasing number of carriers, and high order sectorization as proposed technical solutions.
Assessment of Quality of Service of G.S.M. Networks in Ilorin Metropolis, Nigeria
AJERD , 2020
Following the rollout of GSM services across Nigeria, the socioeconomic landscape of the country has been positively altered. Its explosive growth has brought huge revenues to the operators, as well as the government and at the same time benefited the citizens in many ways. However, the principal developmental factors that has continued to mar these benefits is the aggressive complaints from GSM subscribers regarding the horrible Quality of Service (QoS) rendered by the GSM operators across the country. As the number of subscribers of GSM in Nigeria increased, congestion rates also increased and there has been a huge demand for a decent QoS in the country. In this study, three key performance indicators (KPI) parameters, call setup success rate (CSSR), received signal level (RSL) and call drop rate (CDR) were used in assessing the performance of two of the major GSM networks in Ilorin Metropolis of Nigeria, which have been tagged Network "A" and Network "B". A and B monitored are far from providing reliable services to Nigerians. None of the networks in the study met the ≥ 98% CSSR required by the N.C.C. regulations, and none met the ≤ 2% CDR required by the N.C.C. regulations. The problems GSM operation encountered have been attributed to a number of challenges, with cited faults ranging from the Network providers, to regulatory agencies, and even to the Nigerian Government.
