ABOUT THE REPORT
This is a report produced by the 5G-MAG Workgroup UC (Use Cases, Requirements and Opportunities).
Current version of the report: v.1.0
Date of publication: 27th January 2025
ABSTRACT
Non-Terrestrial Networks (NTNs) may use satellites, for example, to provide connectivity over large geographical areas. In particular, NTNs may deliver Internet and media content to poorly served areas as well as to moving platforms (e.g. cars, trains, aeroplanes) beyond the reach of terrestrial infrastructure.
This report provides a high-level overview of the types of payload, connection and device that might be used to access services on NTNs.
The document goes on to define a set of use cases and requirements identified as relevant to media content distribution over NTNs. These include the use of point-to-point, point-to multipoint and broadcast delivery mechanisms for the delivery of content to different types of device. Several challenges and opportunities to optimize content delivery related to broadcast scenarios and multicast scenarios are also presented. This is done with the application in mind and not assuming any specific exiting technology.
The use case descriptions in this document are intended to lead on to subsequent work reviewing 3GPP specifications to analyse the functional match and, based on this, to identify and document any gaps.
This subsequent gap analysis will identify the areas which may require adaptation to support the NTN scenarios, and is intended as an input to the 3GPP SA Technical Specification Groups.
