QoE-driven voice quality evaluation model of VoIP based on network simulation

The quality of experience (QoE) evaluation model for voice over IP (VoIP) service is studied to analyze the impact of network parameters on voice quality and monitor voice quality in real-time for operators. Firstly, the influence of some network parameters on the voice quality of VoIP is investigated. Then, a simulation platform for VoIP transmission is built to collect voice data under different network enviornments. According to the simulation results, a new mapping model between these arguments and VoIP voice quality is deduced. Finally, the accuracy of this voice quality evaluation model is examined and the results demanstrate that it has high reliability and feasibility.
