One the most important features of a Long Term Evolution (LTE) system is the high transmission data rate in downlink and in uplink. This is not sufficient for a good Quality of Experience (QoE) perceived by the end user. The Mobile Network Operator (MNO) has to adopt appropriate techniques for an effective management of the Quality of Service (QoS) not only for bandwidth-consuming applications as video streaming but also for voice application as Voice Over LTE (VoLTE). These techniques can be based on the QoE/QoS correlation especially in case of a delay-sensitive application as VoLTE. This paper formulates a method for the QoE estimation starting from QoS informations available at network level. Different scenarios are simulated using OPNET software tool. Results are statistically analyzed using regression cluster analysis techniques. Mathematical functions representing relationship between QoE/QoS metrics are identified.
