Traffic Models and Quality Evaluation Methods for Media and XR Services in 5G Systems
- Abstract
- Media services in general, but also in particular eXtended Reality (XR) and Cloud Gaming are some of the most important 5G media applications under consideration in the industry. XR is an umbrella term for different types of realities and refers to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables. It includes representative forms such as Augmented Reality (AR), Mixed Reality (MR) and Virtual Reality (VR) and the areas interpolated among them.On XR and Cloud Gaming traffic with high throughput, low latency and high reliability requirements, it is important to consider system aspects of such services. If the traffic requirements of the XR and Cloud Gaming service are flexible (e.g., the underlying architecture allows adaptation of content), then the capacity of the service can be studied by assessing the delay, throughput and reliability variations with increasing number of users in the system. In order to properly study this, detailed traffic characteristics are necessary.Based on this, the present document provides traffic models and quality evaluation methods for different media and eXtended Reality (XR) Services. In order to address this, generic modelling considerations are introduced and for different services reference designs, simulation models and suitable quality metrics are reported. This information permits to obtain accurate information on exact bitrate and delay requirements in uplink and downlink, develop detailed traffic traces, develop suitable statistical models for media and XR traffic and to evaluate the expected media quality of such services. The information may be used by other 3GPP groups in order to assess media quality for different configuration of 5G System parameters, as well as for evaluating the requirements in terms of QoS for XR and media services.
