1. Document the above key topics in more detail, in particular how they relate to the 5GMS Architecture and protocols.
2. Study collaboration scenarios between the 5G System and Application Provider for each of the key topics.
3. Based on the 5GMS Architecture, develop one or more deployment architectures that address the key topics and the collaboration models.
4. Map the key topics to basic functions and develop high-level call flows.
5. Identify the issues that need to be solved.
6. Provide candidate solutions (including call flows) for each of the identified issues.
7. Coordinate work with other 3GPP groups e.g. SA2, SA3, SA5, and others as needed.
8. Coordinate work with external organizations such as SVTA (in particular DASH-IF WG), CTA WAVE, ISO/IEC JTC29 WG3 (MPEG Systems), or IETF, as needed.
9. Identify gaps and recommend potential normative work for stage-2 call flows and possibly stage-3. |

- Media centric Third-Party and Operator services currently deployed or expected to be deployed until 2025 on 3GPP defined 4G and 5G networks.
- Typical deployment characteristics today, such as bandwidth requirements, client buffered and rate adaptation reception characteristics, codecs, protocols in use and latency requirements.
- An overview on technological developments for existing and emerging services and their impact on typical traffic characteristics of media services, e.g. evolution of compression technologies, new demands for high quality, new experiences, etc.
- A summary on typical characteristics and requirements for different media services on 3GPP networks.
- An identification of the applicability of existing 5QIs for such services and potentially identify requirements for new 5QIs or QoS related parameters. |
26.926 | Traffic Models and Quality Evaluation Methods for Media and XR Services in 5G Systems | TR | 18.2.0 | S4 | https://www.3gpp.org/ftp/Specs/archive/26_series/26.926/26926-i20.zip | 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. |

In specific, the following aspects are addressed in this document:
- To identify relevant use cases that can be addressed using network slicing, and study collaboration scenarios and deployment architectures to support network slicing for media services.
- To identify any missing provisioning aspects for configuring media services with one or more network slices including QoS configuration, reporting and dynamic policy.
- To identify impact of network slicing on dynamic policy invocation APIs, including selection of appropriate network slices for dynamic policy requests, possible migration of UE application traffic flows between network slices due to dynamic policy procedures, discovery of dynamic policy AF, and necessary routing considerations.
- To determine the need and describe methods for AF-to-AF communication to support interoperability if 5GMS AF instances from different vendors are deployed in the same 5GMS System.
- To identify methods for deploying, supporting, and resolving slice-specific 5GMS AS instances.
- To identify potential areas for normative work and communicate/align with SA2 as well as other potential 3GPP WGs (SA5, SA6) on relevant aspects related to the study. |
