ANALYSIS OF THE MOST INFLUENTIAL FACTOR ON QUALITY OF EXPERIENCE IN MOBILE NETWORK
Keywords:
Quality of service (QoS), quality of experience (QoE), feed-forward backpropagation neural network, mean absolute deviation (MAD)Abstract
As the quality of service (QoS) on mobile networks constantly changes, the communication service providers always examine and improve the network performance to maintain the number of customers. In terms of network optimization, communication service providers just focus on adjusting the QoS parameters to the standards of the mobile service but that does not approach the customers’ actual needs. The researchers recognize the importance of the QoS parameters along with the users' satisfaction or users’ experience which are evaluated using the principles of quality of experience (QoE). In this paper, the relationships among the parameters using model creation based on a feed-forward backpropagation neural network are presented. The same evaluator for all evaluations is utilized because the locations are alien in different environments. The activities for the evaluation of the users’ opinions consist of watching the YouTube service, using a web browser, and sending a message via the Line service. These relationships are analyzed to get the QoS parameters that have the most impact on changes of the QoE score using mean absolute deviation (MAD). This study can be used as a guideline for investigation and management of problematic parameters for communication service providers.
