QoS KPI and QoE KQI Relationship for LTE VIdeo Streaming and VoLTE Services
Mobile users today can choose among different competing network operators offers, influenced in their choice by perceived and experienced quality, during the fruition of the service. The network operators must be able to react on quality issues, before the user perceives them. In order to do this, it is essential to establish a link between Quality of Experience (QoE) and Quality of Service (QoS) offered by the network performances. The Long term Evolution (LTE) Standard focuses on QoS definition, but doesn't define the QoS/QoE relationship. This article identifies the QoS a QoE parameters, named respectively Key Performance Indicators (KPI), and Key Quality Indicators (KQI), for Video Streaming and Voice over LTE (VoLTE) services, and then analyzes QoS/QoE mathematical relationship. The main contribution of this research relies on the possibility to predict the expected QoE level through the QoS/QoE relationship for the services under study delivered through LTE network.
