With reference to ITU ,Public Relations and International Affairs TIC announced that :
Ensuring Quality of Service (QoS) in today’s IP-based, communications ecosystem is a complex challenge, and even more so for fast-growing emerging economies experiencing a surge in demand for services and consequent network performance concerns.
The latest ITU-T Recommendation summarizes the basics of Quality of Service, from the user’s perspective. Differences to Quality of Experience (QoE) are also discussed.
ITU-T E.804 defines QoS parameters and their computation for popular services for example e-mail, video streaming and voice in mobile networks. It also describes the measurement procedures needed to perform the measurements of QoS parameters.
It defines the minimum requirements of QoS measurement equipment for mobile networks in such a way that the values and trigger points needed to compute the QoS parameter can be measured following the procedures defined. Furthermore, it specifies typical measurement profiles which are required to enable benchmarking of different mobile networks both within and outside national boundaries.
In addition it describes procedures to be used for statistical calculations in the field of QoS measurement of mobile networks using probing systems.
Finally it describes how Quality of Service measurements should be done inside the network without direct access to the end point terminal.
An additional document (ITU-T E.800 series Suppl. 9 - Guidelines on Regulatory Aspects of QoS) agreed at the December meeting of Study Group 12 in Geneva provides guidelines on the regulatory aspects of Quality of Service (QoS). The intent is to assist regulators or administrations who need to achieve desired levels of QoS for one or more ICT services under their jurisdiction.
