One main motivation of mobile network evolution is to improve the user experience why the evaluation of the user experience at the UE side is vital to network operators, especially when the operators provide some real-time services which require for example high date rate and low latency like streaming services (typically video services) , where even intermittent quality degradation is very annoying. Many of these streaming services are a significant part of the commercial traffic growth rate, therefore the focus is on the end users' experience .
Quality of Experience (QoE) information collection provides detailed information at call level on a number of UEs.
The capability to log information within a UE, and in particular the QoE of an end user service, initiated by an operator, provides the operator with QoE information. The collected information (specified in
TS 26.247) cannot be deduced from performance measurements in the mobile network.
The QoE information is information collected by the end user application in the UE.
The collected QoE information is collected by the management system for analysis and/or KPI calculations.
