[Shenzhen, China, July 9] – Huawei, a leading global information and communications technology (ICT) solutions provider, hosted the ITU-T Q9/12 Rapporteur meeting, in Shenzhen, China, July 1-2, 2013.
Study Groups, held as part of the meeting included questions focused on objective methods for evaluating user-perceived quality in telecommunication scenarios. Discussions and questions from one of these groups, Study Group 12, which looked at performance, QoS and QoE of ITU-T has already resulted in a series of recommendations to be applied widely, for example P.862, P.862.1, P.862.2, P.862.3, P.863, and P.563.
The meeting also included extensive discussion sessions focused on two work items, P.ONR, and P.SPELQ. P.ONRA, Objective evaluation of Noise Reduction Systems, is targeted on a new intrusive objective voice quality evaluation model for noise reduction systems. P.SPELQ, Single-ended Perceptual Evaluation of Listening Quality, is targeted on a new non-intrusive objective voice quality evaluation model for real-time scenarios.
As a proponent of exceptional quality products and services, Huawei has supported the industry application of P.SPELQ. Huawei Media Lab submitted three contributions for this meeting which will act as a foundation to generate advanced drafts of the P.SPELQ requirement specifications, this will mark an important step towards providing real-time quality assessments solution without infringing customers’ privacy.
To build on the foundation of the successful initial discussions and working groups, key stakeholders are expected to continue developing these work items in an effort to improve standards across the telecommunications industry. With the new perceptual model of voice quality evaluation, operators will now be better equipped to ascertain their customers’ true experience quality across voice services, and make improvements based on their findings.
Discussions are expected to continue at the next SG12 meeting to be held in Geneva, December 2013.
