Rapporteur:  Mr. Rognant, Pierre

The scope of this Technical Report is to study:
  • The identification of impact areas of satellite integration in the 5GS, when considering TR 22.822 use cases.
  • The identification of solutions to adjust the 5G system for the impact impacts areas for the reference use cases:
    • Roaming between terrestrial and satellite networks.
    • 5G Fixed Backhaul between Satellite Enabled NR-RAN and the 5G Core.
  • The resolution of RAN and CN inter-related issues.
