To let the service system react quickly on customers' perception or user experience while using the service, mapping functions between QoE and QoS are strongly required in purpose of building up an intelligent QoE control system upon adjusting QoS parameters. This paper studies the changing behavior of QoE with respect to changes of QoS parameters in the context of video streaming service in an IMS-based IPTV network. QoE in both terms of Mean Opinion Scores and VQM is studied as functions of loss, jitter, and delay. The QoE-QoS correlation could be a significant first step to build a smart QoE monitoring and control mechanism as an added value to promote the IMS- based IPTV network.
