  1. QoSRecherche des critères, paramètres et indicateurs pertinents pour les utilisateurs Réunion QOSTICParis 10 Décembre 2003P-Y Hébert - AFUTT/ETSI

  2. Lacks in current standards • In the following slides: • This colour means: QoS parameter covered in one existing standard from the end-user point of view • This colour means: QoS parameter covered in one existing standard for measurement method • Therefore work is needed everywhere it's blue

  3. Lacks in current standards • Provision • Preliminary information • Supply time for service access • Completion efficiency • Contract clarity • Contract flexibility

  4. Lacks in current standards (2) • Operation • Service availability • Coverage (mobile networks) • Unsuccessful call ratio • Set-up swiftness • Absence of dropouts • Speech or data quality • Flow rate or transactions time • Number of call to report fault. • Exchange security • Terminal protection

  5. Lacks in current standards (3) • Customer services • Swiftness of after-sales service to answer calls • Efficiency of after-sales service • Swiftness to repair • Availability of operator services • Efficiency of help line

  6. Lacks in current standards (4) • Billing • Bill correctness/Accuracy (counting and tariff) • Bill presentation quality • Number of claims • Response time for admin/billing enquiries • Other services • Directory service availability • Response time • Relevance of the answers

  7. Next steps: • EG 202 009 QoS parameters review • EG 202 009 revision • Have it acknowledged by the European and national regulation

  8. EG 202 009 Parameter Review • Each QoS parameter belongs to one of the4 following QoS Criteria • Availability • Reliability • Response time • Capacity • A set of parameters is to define (incl. acceptable range) in each of the application segments and subsegments: • Audio • Video • Data • Background applications and Others • Fax • Newsgroups, etc

  9. EG 202 009 Parameter Review (ctd)Application segments and subsegments • Audio: • Telephony • Voice messaging • Streaming audio • Video: • Videophone • Oneway video

  10. EG 202 009 Parameter Review (ctd)Application segments and subsegments • Data: • Web browsing • Bulk data transfer/retrieval (FTP) • High priority transaction services (E-commerce) • Command/control • Still image • Interactive games • Telnet • E-mail (Server Access) • Instant messaging

  11. EG 202 009 Parameter Review (ctd)Application segments and subsegments • Background applications: • Fax • Low priority transaction services (SMS) • E-mail (server to server transfer) • Newsgroups (Usenet)

  12. QoS Parameter Review (ctd) • The existing EG 202 009 parameters have to be reviewed to conform to the 4 criteria and appropriate segmentation • The missing QoS Parameters shall be defined • A tentative framework for this revision for discussion during this meeting

  13. EG 202 009 revision • Provision: a lot to add • Operation: several aspects to add • Mobile QoS (coverage, GPRS, etc) • Internet QoS. • Exchange security • Terminal protection • etc • Customer services • Billing • Correctness/Accuracy • Bill presentation quality • Response time for admin/billing enquiries • and many others ...

  14. EG 202 009 revision • Beside the parameter review, provide guidance to the user needs analysis for the definition of appropriate classes of services (Part 1) see ITU-T G1010 • In addition to the end-to-end QoS concept (same parameter whatever the bearer network) define the perimeter for QoS parameter measurement.

  15. EG 202 009 revision (ctd) • Tentative measurement perimeters: • Over the supplier networks • Switched communications over fixed network • Switched communications over mobile network • Switched communications from fixed to mobile terminals • Switched communications from mobile to fixed terminals • IP communications over fixed network • IP communications over mobile network • Switched communications over international fixed networks • Switched communications over international Mobile Networks
