조건부 핸드오버(CHO), 빠른 위성 통과 시 측정 보고, 지상 5G NR과 NTN 빔 간의 이중 연결(Multi-RAT DC) 트래픽 분할 및 무중단 비상 세션 연속성을 위한 엔지니어링 메커니즘.
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.
