NTNCommunications: 통합 비지상 통신 체계 및 멀티 궤도 5G/6G 융합 네트워크

NTNCommunications는 저궤도, 중궤도, 정지궤도 위성 및 성층권 HAPS를 글로벌 3GPP 셀룰러 망에 유기적으로 통합하는 표준 프로토콜 프레임워크를 수립합니다.

NTNCommunications 3D Heterogeneous Non-Terrestrial Network Topology

Harmonized control plane unifying terrestrial cellular with multi-orbit constellations

Central System: Terrestrial Sub-6GHz / mmWave RAN - High-density urban microcells and regional macro towers

Network Nodes

  • Terrestrial Sub-6GHz / mmWave RAN
  • Stratospheric HAPS Layer (20 km)
  • Dense LEO Constellation (600 km)
  • Unified 3GPP Rel-18/19 Core Network

Architectural Protocol Layers

  • Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
  • Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
  • Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
