Means and methods for collecting and analyzing QoE measurements in wireless networks

Two practical approaches are possible for QoE monitoring: service performance measurements using statistical samples; and network management system (NMS) using QoS parameters. This paper introduces both methodologies. Fundamental QoE performance metrics are presented and the statistical confidence on measured data is discussed. The proposed method for collecting service level metrics makes use of a mobile QoS agent (MQA) installed in handsets. An MQA is described and validated in a real 3GSM network by means of prototyping. Experimental results show the validated MQA concept to be an appropriate solution for QoE monitoring
