Feasibility Study on satellite access - Phase 4
The present document describes use cases and aspects related to enhancements of the 5G system over satellite, including:
• multi-orbit satellite access for multiple services
• resilient notification
• support for emergency communications and mission critical services using satellite access
• support IMS voice calls using GEO satellite access
• Broadcast services with satellite access for unregistered UEs
NOTE: In the present document, the terms GEO (geostationary) and GSO (geosynchronous) are equivalent, unless indicated otherwise
