Results from groups directly belong to Plenary

  • Handled numerous incoming Liaison statements which were related to workprogramme and entire SG12 activities drafting replies as appropriate.
  • Developed plans to progress the work on Bridging the Standardization Gap (BSG) issues.
      •  E-learning course on QoS: SG12 reviewed the draft material and provided feedbacks.
  • Examined the SG12 Workprogramme.
  • Coordination of activities on QoS and QoE within ITU was discussed 
      • It was identified that the draft Recommendation ITU-T Q.QMS “The Framework of the QoS/QoE Monitoring system”, which is under development within ITU-T SG11, is conflicting with substantial work on QoS/QoE monitoring conducted in SG12, reflected in standards such as P.564, P.1201, P.1202 and the running work items P.NATS and P.INQX.  To clarify the situation and mitigate the problem, a Liaison Statement was sent to ITU-T SG11.
  • Consented the following Recommendations:
      • Revised Recommendation ITU-T G.100.1 “The use of the decibel and of relative levels in speechband telecommunications”
      • Amendment 4 to Recommendation ITU-T P.10/G.100 “Vocabulary for performance and quality of service”
  • Handbook on “ITU-T Recommendations under Study Group 12 responsibility” was discussed
Regional Group for Africa
  • Reviewed and updated its workprogramme
  • Planned the next SG12 RG-AFR meeting, which is to be collocated with a Regional Standardization Forum (see “Future meetings and workshops” for more details)
Quality of service development group (QSDG)
  • Updated the QSDG Workprogramme for 2015/2016 and planned the next meetings and workshops (see "Future meetings and workshops" for more details).
