3/12/20037 Next steps: EG QoS parameters review EG revision Have it acknowledged by the European and national regulation

3/12/20038 EG Parameter Review Each QoS parameter belongs to one of the 4 following QoS Criteria 3Availability 3Reliability 3Response time 3Capacity A set of parameters is to define (incl. acceptable range) in each of the application segments and subsegments: 3Audio 3Video 3Data 3Background applications and Others Fax Newsgroups, etc

3/12/20039 EG Parameter Review (ctd) Application segments and subsegments Audio: 3Telephony 3Voice messaging 3Streaming audio Video: 3Videophone 3Oneway video

3/12/ EG Parameter Review (ctd) Application segments and subsegments Background applications: 3Fax 3Low priority transaction services (SMS) 3 (server to server transfer) 3Newsgroups (Usenet)

3/12/ QoS Parameter Review (ctd) The existing EG 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

3/12/ EG revision 3Provision: a lot to add 3Operation: several aspects to add Mobile QoS (coverage, GPRS, etc) Internet QoS. Exchange security Terminal protection etc 3Customer services Billing Correctness/Accuracy Bill presentation quality Response time for admin/billing enquiries and many others...

3/12/ EG 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.

3/12/ EG revision (ctd) Tentative measurement perimeters: 3Over 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 3Switched communications over international fixed networks 3Switched communications over international Mobile Networks
