Abstract

Recently, many companies are moving from PSTN to packet-switched networks as it provides easier access to voice communication anywhere in the world. VoIP Quality is one of the important problems service providers want to solve as providing QoS guarantees in VoIP applications becomes more challenging in wireless and mobile networks. In this paper, we used a methodology of Listening and Rate-Opinion Trial (LRT) in order to define the burst boundary, which enables users to identify if they are satisfied with their experiences in a short period of time. We derived the charging rate algorithm that can be used as a reference for calculating the “delivered packet amount”-based prices by observing the connection between PESQ MOS and the gap ratio for sex samples of both English and Korean. The connection of PESQ MOS and the gap ratio could be obtained by measuring the burst. The charging rate algorithm can be derived from the measured gap ratio.
