Summary:
|
This Technical Report defines a scope for the analysis of QoE in 5G services and several use cases where this scope is applicable. Such use cases are: Tele-operated Driving, Wireless Content Production, Mixed Reality Offloading, and First Responder Networks.
Addressing this set of use cases is challenging for three different reasons:
Their requirements and Quality of Experience (QoE) expectations may be different from the ones typically present in most QoE-related research and Recommendations, which typically address communication services for consumer-type users (e.g., telephony, videoconference, video delivery / streaming, gaming, etc.).
The experience and expectations of the use case owners may not be applicable to cellular wireless networks, even when QoS policies are applied. E.g., a wireless content production studio will not have the same channel capacity as a wired network, neither from bandwidth nor from reliability points of view. Therefore, totally new impairments or artifacts may appear when moving the use case from wired links to 5G.
Professional and vertical applications typically have less users than the video consumer ones (there are fewer content producers than content consumers), or the video transmission is just one of the pieces of a much more complex ecosystem (as in the automotive industry).
For each of the services, the document describes:
Its main characteristics and reference architecture.
The relevant QoE indicators to be considered on the service.
A reference implementation, including the order-of-magnitude values of the service Key Performance Indicators, and
An analysis of the key factors to evaluate the QoE of the service.
