Quality Assessment in 3G/4G Wireless Networks

The convergence of wireless networks and multimedia communications, linked to the swift development of services and the increasing competition, has caused user expectations of network quality to raise. Network quality has become one of the main targets for the network optimization and maintenance departments. Quality of experience (QoE) has been traditionally assessed via subjective tests, but this is a costly method. In recent years, different methods for assessing QoE from objective parameters have been proposed. In this paper we describe a non-intrusive system for the analysis and measurement of QoE in wireless networks from these objective parameters. The system consists of mobile agents running on the mobile terminals and one or more network entities that collect and analyze the information.
