| Abstract(in English) | Quality visualization and quality control during service are important to ensure that voice call applications are used with comfortable quality. The purpose of this study is to construct a packet-layer quality evaluation model for voice call applications. Concretely, the proposed method evaluates QoE by estimating packet loss rate and packet delay jitter in the network, targeting received packets of voice call applications employing silence compression coding technology. Received packets are affected by silence compression as well as network quality. Therefore, it was shown that the listening quality can be estimated from the received packets by estimating the packet loss rate and packet delay jitter considering the percentage of voice sections. |
