  1. JYM.C.I.S ETSI STQSpeech and multimedia Transmission Quality 2009 Results and plans for 2010 Jean-Yves Monfort; ITG/JYMCIS Jeanyves.monfort.6@orange.fr ETSI STQ Presentation

  2. Description ETSI STQ Presentation 2

  3. Speech and Multimedia QoS/QoE ETSI STQ Identity Card • Current Work • User related QoS &Acoustic safety • NGN related quality (eg FAX) • Speech Terminal requirements and tests • Testing Mobile services Quality • Multimedia and Audiovisual Quality • Quality metrics (speech, multiplay,…) • Plugtests on speech quality • Collaborations within ETSI • DECT, HF, SAFETY, TETRA,TISPAN, USER, ATTM • 3GPP [SA4] • Standardization Partners • ITU-T (SG12, SG16, SG13), TIA, DECT Forum (CatIQ)CEN/CENELEC, GCF, IEEE, CTIA • Research Partners • University of Zilina, CINI Potentially • Technical University Berlin, Telecom Paris Potential Future Work • Superwideband and fullband terminals • Guidelines to improve quality of electronic tools used for meetings, conferences,… • Measurement standards & best practices for speech and multimedia terminals and services, for all (access) networks • E2E quality in interconnection scenarios Ensuring standards for enhanced quality and use of services Requirements and test methods to provide and monitor media Quality to Users ETSI STQ Presentation 3

  4. Terms of Reference TC STQ (3 meetings/year - 3x5 days) Speech (Narrowband wideband super WB&Fullband ) quality, but also now multimedia Quality - User related QoS Metrics and test methods for media quality NGN related QoS Strong collaborations inside ETSI (DECTDECT Forum/CATiq, TISPAN, User) and outside ETSI ( mainly ITU-T SG12 and 3GPP SA4, GCF) Interoperability events, Workshops and STFs WG STQ Mobile (4 meetings/year – 4x2 days) QoS parameters and test methods for popular services in GSM & 3G Networks (a set of 6 TS, continuously updated)  drive tests Collaborations with 3GPP SA and IREG and recently with ETSI TETRA ETSI STQ Presentation 4

  5. Test Methods Plugtests • STQE. Tests including acoustical interface for IPGW and IPphones. A new programme includes DECT terminals 5 STQEvents already done TR 102 648 Series provide test methods and results (anonymous reports) To be noted: Need to improve echo and double talk performance performances aux niveaux écho et double parole. • Speech quality analysis in context of interworking Plug test for multiplay services (tests done at the electrical interface) TR 102 716series on test methodology and recently approved a TR providing results of a test campaign ETSI STQ Presentation

  6. User related QoS (1/2) • New plans in STQ and STQ Mobile: to defined a QoS/QoE framework • Objective: October 2010 • Inputs to ITU-T QoS Handbook ETSI STQ Presentation

  7. User related QoS (2/2) • REG/STQ-00101: Series (Revision of EG 202 057 Series) • Recently updated: User related QoS parameter definitions and measurements; Part 2: Voice telephony, Group 3 fax, modem data services and SMS Ongoing work: new QoS parameters in the context of NGN. A first result: the new parameter " Call establishment delay" for NGN has been defined  a new TR "Measurements of Call Establishment Performance in IP Networks" has been approved in jan.2010 • This new parameter could be added in the future release of EG 202 057 -2 ETSI STQ Presentation

  8. NGN related QoS and multimedia • STF363 "Quality of service implications of NGN architectures" • A workshop was organised in 2009 (with STF360) • TR102 717 has been published  Describes different reference configurations, identifies standardization gaps and provides roadmap for future actions. • A new TR 102 720 on "Delay variation on access lines".  It explains the mechanism of serialisation delay, gives a (very general) overview over prioritisation and shows how the maximum delay variation due to concurrent traffic can be calculated.. ETSI STQ Presentation

  9. NGN related QoS and multimedia • Perceptual Impact of End-to-End Delay Variation on Fax over IP & Modem over IP • Ongoing work within STF 392. • Framework for end-to-end quality assessment of multimedia services • This Framework could be finalised in June 2010 • ES 202 667 Audiovisual QoS for communication over IP networksRecently updated for LTE and Cable networks  in MV ETSI STQ Presentation

  10. Metrics and Measurement methods • EG 201 377 series "Specification and measurement of speech transmission quality". Part 1 & 2 recently updated and approved • EG 201 377Part 1: Introduction to objective comparison measurement methods for one-way speech quality across networks • ES 201 377 Part 2: Mouth‑to‑ear speech transmission quality including terminals • Part 3: There is a need to update it, but still pending ETSI STQ Presentation

  11. QoS and network performance metrics (1/2) EG/ES 202 765 Series QoS and network performance metrics and measurement methods • Part 1: Generals: indicators displayed according to ITU-T Rec P.505 and not using a single score. • Part 3: Network performance metrics and measurement methods in IP networks (comparisons of parameters defined by IETF and ITU-T. Both recently aproved ETSI STQ Presentation

  12. QoS and network Performance metrics and measurement methods (2/2) - Part 4 (ES): Indicators for supervision of Multiplay services • STQ agreed on the parameters defined for IPTV and VoD. • Video sequences with impairments (Blockiness, Black Screen, Frozen Picture) are freely available. • A table compares tjhe indicators defined for mobile TV (TS 102 250-2 produced by STQ Mobile) and the indicators of DES 202 765-4 • Plan: to aprove it at STQ June meeting • ES 202 765 part 2: Transmission Quality indicators combining Voice Quality metrics.Release 2 in MV ETSI STQ Presentation

  13. Speech Terminals (narrowband and wideband) (1/2) • Transmission requirements for VoIP terminals from a QoS perspective as perceived by the user • Release 2 of ES 202 737 (Narrowband handset/headset), ES 202 738 (Narrowband handsfree), ES 202 739 (wideband handset/headset) and ES 202 740 (wideband handsfree). • DECT EN have been derived from these ES.  CAT iq ETSI STQ Presentation

  14. Speech Terminals (narrowband and wideband) (2/2) • Transmission requirements for wireless terminals from a QoS perspective as perceived by the user • Four TS 103 737, 738, 739, 740 with structures similar to the ES for VoIP • Release 1 aproved in Sept. 2009  GCF  Inputs to 3GPP SA4 & ITU-T SG12 ETSI STQ Presentation

  15. Speech Terminals • New draft EN for maximum acoustic levels. (Mandate M452) • Home gateways • New WI covering wired et wireless accesses and taking into account impairments on access and IP networks. DES 202 718 • A new method for PLC testing ETSI STQ Presentation

  16. Speech TerminalsSuperwideband/Fullband • A New W (Scope agreed in January)  conversational services, teleconference,.. ETSI STQ Presentation

  17. Next events • STQ 34 Berne, June 11-15 • Workshop on QoS/QoE- Focus on Quality and usage of Electronic tools for meetings and conferences. ETSI Premises, Sophia Antipolis, September 21-22 • STQ 35 Sophia Antipolis, October 4-8 ETSI STQ Presentation

  18. Major activities/deliverables - WG STQ Mobile Regular update TS 102 250 Series to take into account new services , eg WAP parameters, DVB-H specific QoS parameters, Test methodology respective to Store&Forward parameters; Streaming & Timeouts Media download Recently STQ mobile has agreed to consider ongoing standardization work for MTSI services and collaborate with TETRA on end to End QoS In complement STQ mobile has already published Technical Reports in addition to TS 102 250 series : TR102 506 : Estimating speech quality per call TR 102 505 : Development of a reference web page (Ongoing revision) TR 102 581 : a study on the minimum additional required attenuation on the antenna path of field test equipment TR 102 529 on SMS testing guidelines TR 102493: Guidelines for the use of video quality algorithms for mobile applications ETSI STQ Presentation 18 18
