Providing Quality-of Service (QoS) guarantees in VoIP applications becomes more challenging in wireless and mobile networks. One of the important issues is to find a mechanism that can probe to what degree the users are satisfied with their experiences and give them service quality guarantees with varying prices depending on the network performance they may experience. In this paper, we use a methodology of listening and identifying word-by-word in order to obtain the criterion metric, which enables users to identify whether they are satisfied with their experiences or not. Investigating the relationship between the gap ratio and PESQ MOS, we derive the charging ratio, which can be used as the proportion of quality-based prices to ''delivered packet amount''-based prices. Finally, we design the charging ratio model which can be a key component of quality-based VoIP charging mechanism.
Abstract
Providing Quality-of Service (QoS) guarantees in VoIP applications becomes more challenging in wireless and mobile networks. One of the important issues is to find a mechanism that can probe to what degree the users are satisfied with their experiences and give them service quality guarantees with varying prices depending on the network performance they may experience. In this paper, we use a methodology of listening and identifying word-by-word in order to obtain the criterion metric, which enables users to identify whether they are satisfied with their experiences or not. Investigating the relationship between the gap ratio and PESQ MOS, we derive the charging ratio, which can be used as the proportion of quality-based prices to ''delivered packet amount''-based prices. Finally, we design the charging ratio model which can be a key component of quality-based VoIP charging mechanism.
