Abstract:
This work introduces a mathematical relationship linking Quality of Experience (QoE) and Quality of Service (QoS) in Voice over LTE (VoLTE) services. An OPNET simulation model is used to validate the relationship. A real world test is reported that confirms the simulation validation. Besides its academic interest, knowledge of the relationship can provide LTE network management a way to predict the QoE offered to VoLTE users, by simply basing on measurements of the network QoS.
