Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Human Factors (HF). ETSI ETSI TR 102 643 V1.0.2 (2010-01) 51 Scope

18、The present document is based on Guidelines produced in Specialist ETSI Task Force 354 and a Web-Based Guideline access and Tutorial System (WBGTS) (http:/portal.etsi.org/stfs/STF_HomePages/STF354/STF354.asp). The main content of the WBGTS are Quality of Experience (QoE) guidelines for real-time com

19、munication services expressed in Quality of Service (QoS) terms. The Guidelines and the present document are primarily intended for professionals in network operator, equipment manufacturer and service provider organisations who are concerned with the user experience of communication services. Over

20、the last 10 years that include pre-cursor projects to STF 354 about 2000 intended guideline users have been involved in the development work of the WBGTS. The present document describes an assessment of the current guidelines and the tutorial system and identifies needs for future work. 2 References
