Engineering mechanisms for conditional handovers (CHO), measurement reporting across rapid satellite passes, dual-connectivity (Multi-RAT DC) splitting traffic between terrestrial 5G NR and NTN beams, and zero-drop emergency session continuity.
Deploying hybrid satellite-cellular roaming in non-terrestrial environments requires solving fundamental physics constraints: path loss over 1000km distances, rapid carrier frequency shifts due to Doppler effects, and power-thermal limits of spaceborne hardware. The architecture provides deterministic mitigation strategies.
The protocol workflow for hybrid satellite-cellular roaming coordinates physical layer signal acquisition with higher-layer transport resilience. By leveraging open-loop ephemeris calculations and adaptive retransmission timers, communication links maintain uninterrupted throughput across satellite handoffs.
