2 What is ETSI European Telecommunications Standards Institute An independent, not-for-profit organization, created in 1988 The home of GSM standards and founding partner in We have 16,000 publications - freely available! 2

3 ETSI s Mission Develop globally applicable deliverables meeting the needs of the Information and Communication Technologies (ICT) community, whilst supporting EU and EFTA regulation and initiatives. In order to achieve its mission, ETSI favours international collaboration. 3

4 ETSI s three primary roles ESO European Standards Organization GSO Global Standards Organization SP Service Provider European Standards (EN) Harmonised Standards (HS) Technical Specifications (TS) Technical Reports (TR) ETSI Standards (ES) ETSI Guides (EG) Interoperability service Forum hosting and secretariat services 4

13 Quality-focused Technical Bodies in ETSI STQ Speech Transmission and Quality aspects Centre of expertise and co-ordination for QoS aspects Horizontal approach to the other ETSI Technical Bodies EPP 3GPP TISPAN 3GPP: specifications of 3 rd Generation Mobile Systems 4 Technical Bodies divided in 17 Working Groups 3 Working Groups produce specifications on QoS Standardizing Next Generation Networks (NGN) NGN: fixed-mobile network convergence to packetswitched technology delivering multimedia services Divided in 7 Working Groups Working Group 5 (WG5) focuses on NGN QoS Approximately 130 deliverables on quality 13

14 QoS for NGN QoS Requirements for NGN and Multimedia Services Considerations on quality for speech over packet networks VoIP QoS measurement parameters and testing methods (NGN: fixed-mobile network convergence to packet-switched technology delivering multimedia services) Καλησπέρα, τι κάνετε; 14

15 QoS for Mobile 3GPP UMTS introduced end-to-end QoS concept for 3G Mobile Networks Release 5 and 6 QoS class definition considering multimedia services Ongoing work: QoS aspects for popular services in GSM and 3G Networks New interests: Push-to-talk 15

16 Background noise Speech quality performance in presence of background noise Guide for background noise simulation scenario Database (Background Noise signals), freely available Development of standardised performance testing methodology for background noise transmission 16

17 Excessive Acoustic Pressure Excessive acoustic pressure can be harmful for listener Conformance with the limits defined in the 73/23/EEC Directive STQ defining the measurement methods to test the maximum acoustics pressure of terminals 17

18 User-related QoS Frequently updated, comprehensive Guide (ETSI EG ) Generic QoS Voice telephony, Group 3 fax, modem data services and SMS QoS parameters specific to mobile services Internet QoS parameters Focus on User-perspective 18

19 Testing events, Workshops Speech Quality & VoIP Testing activities October 2000 in Germany April 2002 in Germany June and September 2004 in Germany and USA April 2005 in France Upcoming November 2005 in Taiwan Wide-Band Speech Annual workshop in Germany, Mainz Wideband Speech, Prediction and assessment 19

20 What s next? QoS is fundamental best effort not enough for services of the future ETSI defining QoS framework for Next Generation and Mobile Networks QoS for multimedia is the next challenge ETSI has the expertise to meet that challenge ETSI Standards for business 20
