Use Case 3:

Federated NTN​

Traditionally, satellite networks and terrestrial cellular networks have been developed separately, with cellular network technology being standardised in the 3rd Generation Partnership Program (3GPP). One of the important outcomes of standardisation is the support of roaming between networks in different countries. Satellite networks, on the other hand, have often used proprietary technology, and roaming between satellite networks was not considered important as they already provided coverage for large parts, if not most, of the world. However, with the advent of 5G standardisation, there has been increased interest from the satellite communication community to integrate with the 5G ecosystem. This has led to activities within 3GPP to specify how satellite communication can be integrated into 5G, starting with a study in 2017 to specify use cases and requirements for satellite integration.


UC3-Experiment-1: Mobile Industrial Assets supported by NTN Edge Cloud and Communications

6G NTN Cloud Systems follow determined mobility pattern. Thus, the effects of these dynamics are investigated so that resilient operation of such 3D cloud systems is ensured.

UC3-Experiment – 2 Multi-Operator and Multi-Access in NTN

Integration of NTNs and terrestrial networks is required to provide service continuity and scalability in Beyond 5G systems. The second Experiment scenario will go beyond traditional 5G systems and it will examine:

An inter-PLMN handover for a UE moving from one PLMN (terrestrial 3GPP access) to another PLMN (satellite 3GPP access) while maintaining its ongoing session, from Operator A to Operator B

A dual-connectivity scenario in which MPTCP will be used to combine the terrestrial and the (emulated) satellite network paths in a single TCP connection
