Providing quality-of service (QoS) guarantees in VoIP applications becomes more challenging in wireless and mobile networks. Then, 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 the traditional telephone services, the issue of the quality-based accounting has been relegated to the margins of quality communications. Also existing studies to date rarely deal with quality-based VoIP accounting because it is very difficult to find a suitable VoIP accounting metric. In this paper, we use a methodology of listening and identifying word by word and derive a VoIP accounting metric. Using the accounting metric, we design a quality-based VoIP charging mechanism with a “no charging” window.
Abstract
Providing quality-of service (QoS) guarantees in VoIP applications becomes more challenging in wireless and mobile networks. Then, 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 the traditional telephone services, the issue of the quality-based accounting has been relegated to the margins of quality communications. Also existing studies to date rarely deal with quality-based VoIP accounting because it is very difficult to find a suitable VoIP accounting metric. In this paper, we use a methodology of listening and identifying word by word and derive a VoIP accounting metric. Using the accounting metric, we design a quality-based VoIP charging mechanism with a “no charging” window.
