ITU-T SG12, QSDG Workshop, Buenos Aires 24-25 July 2014

Secretary of Communication Argentina hosts the ITU-T workshop on “”Monitoring and Benchmarking of Quality of Service (QoS) and Quality of Experience (QoE) of Multimedia services in Mobile Networks”. Workshop is conducted by the Quality of Service Development Group (QSDG) 24-25 July 2014 in Buenos Aires, Argentina.

Omnitele has been actively contributing to ITU-T QSDG work during past years. In the upcoming QSDG meeting Omnitele gives a keynote speech on topic “Benchmarking and optimising the Customer Experience of Mobile Multimedia Services”. Topics discussed:

  • What is quality of experience, quality of service and network performance
  • Mobile Operator’s QoE challenge: understand how network performance impacts QoS and QoE
  • Case studies on how to benchmark and optimise customer experience


For years, operators have relied almost solely on bitrate as the single KPI to measure, benchmark and optimise their networks for mobile data. But in modern mobile networks the bitrates are often so high that in many cases there are other factors imposing more limits on mobile data customer experience. For some use cases, e.g. VoIP, high bitrate is not required at all, and sometimes not even a very high bitrate allows for acceptable customer experience. Thus, true customer oriented test cases and KPIs are imperative for modern network benchmarks and optimisation.

The challenge has been how to link QoE, QoS and network performance together. In the presentation Omnitele describes a framework for achieving it by mapping mobile subscriber customer experience to selected network performance KPIs.

About ITU-T SG12, Quality of Service Development Group (QSDG)

In the ITU-T, Study Group 12 is the Lead SG on Performance and Quality of Service (QoS), a role that is increasingly important with the advent of commercial VoIP and packet-based next generation networks and terminals. With customers expecting the QoS of traditional communication services, it is crucial to be able to measure new parameters such as packet loss and jitter, and know their user impact. Thus, recent SG12 achievements include several new and revised standards on the planning and deployment of IP-based networks.
