Q13/12 (Presentation Web page is available here)

| Title:
|
Quality of experience (QoE), quality of service (QoS) and performance requirements and assessment methods for multimedia applications
|
| Description:
|
1 Motivation
A major challenge for emerging IP-based networks is to provide adequate quality of experience (QoE) and quality of service (QoS) for new multimedia services and applications. An example is extended reality (XR) applications, including augmented reality (AR), mixed reality (MR), and virtual reality (VR). In such applications, QoE is critical because bad quality may cause people using it have nauseas and sickness. Another example is new services emerging in fixed, mobile, ultra reliable low latency communications (uRLLC) and massive machine type communications (mMTC) broadband. All of these services are inherently multi-media, incorporating audio, video, environments, and interactive control functions, and the QoE is affected by many different categories of factors. The performance requirements and associated measurement methodologies for each of these aspects need to be defined.
The following major deliverables, in force at the time of approval of this Question, fall under its responsibility: G.1010, G.1011, G.1030, G.1031, G.1032, G.1034, G.1035, G.1036, G.1040, G.1050, G.1070, G.1071, G.1072, G.1080, G.1081, G.1082, G.1091, G-series Suppls 73 and 77, P.917, P.919, P.1010, Y.1562.
2 Question
Study items to be considered include, but are not limited to:
- development of new Recommendations providing guidance on QoE target evaluation and measurement;
- identify end-user performance expectations and associated metrics for audio, video, text, graphics quality and control functionality;
- define the key performance parameters and values required to satisfy end-user expectations;
- determine how these requirements can be related to the underlying network, server, and terminal;
- identify simple analysis techniques for estimating end-to-end performance for multimedia applications;
- identify QoS/QoE monitoring methodologies for multimedia services;
- identify sets of KPIs and QoS metrics for different services and investigate the relationship with QoE;
- investigate techniques and methods to perform complex data processing and to make consistent and significant decisions for quality management and assurance;
- multimedia performance considerations for IP gateways;
- QoS and QoE considerations for new services in fixed, mobile broadband, ultra reliable low latency communications (uRLLC) and massive machine type communications (mMTC).
3 Tasks
