Workshop on Quality of Experience-based Management for Future Internet Applications and Services (QoE-FI)

Friday, 12 June 2015 • 09:00 – 18:00

WS-04: Quality of Experience-based Management for Future Internet Applications and Services (QoE-FI)

Organizer: Raimund Schatz (Telecommunications Research Centre Vienna, Austria)

To enable the rapid and widespread adoption of advanced applications like social TV, immersive environments, mobile gaming, HDTV over mobile, 3D virtual worlds, social networking, and IPTV, the overall service quality as experienced by the end user must be taken into account and maximized during capturing of content, processing, delivery over networks, and presentation on users' terminals. In addition, media processing and consumption in the cloud requires significant attention to timely execution of application-related quality requirements via dynamic resource provisioning and efficiently pipelining of processing tasks. In this dynamically evolving context, network operators are forced to keep their increasingly sophisticated customers happy while remaining profitable, requiring proper optimization and management of the QoE (Quality of Experience) for the products and services offered. With this background, the QoE-FI workshop will bring together researchers from academia and industry to identify, discuss and address technical challenges related to QoE measurement and management.

Welcome Session

Keynote-1: QoE Management for Telephony and Gaming Services: Some Thoughts and Concepts

The range of telecommunication services available on the market is wide, and even more widespread is the depth with which Quality of Experience (QoE) considerations have penetrated service design, planning and management. Whereas sophisticated models predicting QoE for speech (and partially also video) telephony are available, and online monitoring permits these models to be used during service operation, far less is known about QoE for new emerging services, such as cloud gaming. In addition, little is known about how QoE management finally influences user experience and acceptance. In this talk, I will try to identify open gaps for research which might lead to new QoE management paradigms for both traditional as well as emerging services.The basic assumption is a broad concept of QoE as reflected in the recent definition from the Qualinet group. This QoE concept includes not only the physical signals reaching the user, but also other system, user and context-of-use factors. For some of these factors subjective and partially also instrumental measurement principles are known; for others, there is a gap which might be filled by new rating or physiological paradigms. Then, models predicting some of these QoE aspects on the basis of signals or parameters will be addressed, and it will be pointed out which of them might be helpful for QoE management. Finally, methods for manipulating system and service factors for improving perceived QoE will be addressed. These methods might be based on the measurement of technical characteristics or of user factors, behavior and state.
