摘要/Abstract

Abstract:

Quality of Experience (QoE) is used to monitor the user experience of telecommunication services, which has been studied for a long time. In universal terrestrial radio access network (UTRAN), evolved UTRAN (E-UTRA) and Long Term Evolution (LTE), QoE has also been specified for the improvement of user experience. The 5G New Radio (NR) technology is designed for providing various types of new services, and therefore operators have strong demand to continuously upgrade the 5G network to provide sufficient and good QoE for corresponding services. With new emerging 5G services, 5G QoE management collection aims at specifying the mechanism to collect the experience parameters for the multimedia telephony service for IP multimedia subsystem (IMS), multimedia broadcast and multicast service (MBMS), virtual reality (VR), etc. Taking LTE QoE as a baseline, generic NR QoE management mechanisms for activation, deactivation, configuration, and reporting of QoE measurement are introduced in this paper. Additionally, some enhanced QoE features in NR are discussed, such as radio access network (RAN) overload handling, RAN-visible QoE, per-slice QoE measurement, radio-related measurement, and QoE continuity for mobility. This paper also introduces solutions to NR QoE, which concludes the progress of NR QoE in the 3rd Generation Partnership Project (3GPP).

Key words: NR, QoE, measurement collection, activation, deactivation, mobility, RAN visible QoE, radio?related information

QoE Metric	Description
Corruption duration metric	The time period from the NTP time of the last good frame before the corruption to the NPT time of the first subsequent good frame
Successive loss of RTP packets	The number of RTP packets lost in the successive per media channel
Frame rate	The playback frame rate is equal to the number of frames displayed during the measurement resolution period divided by the time duration (in seconds) of the measurement resolution period
Jitter duration	Jitter happens when the absolute difference between the actual playback time and the expected playback time is larger than JitterThreshold milliseconds
Sync loss duration	Sync loss happens when the absolute difference between value A and value B is larger than SyncThreshold milliseconds
Round-trip time	The RTT consists of the RTP-level round-trip time, plus the additional two-way delay due to buffering and other processing in each client
Average codec bitrate	The bitrate is used for coding “active” media information during the measurement resolution period
Codec information	The codec information metrics contain details of the media codec settings used in the receiving direction during the measurement resolution period
