NTNReady: 3GPP Rel-17/18 NTN 상용화 준비 인증 및 이동통신사 검증

NTNReady Carrier Conformance & Automated Pipeline Architecture

Multi-scenario orbital delay, Doppler, and fading profile verification harness

Central System: Device Under Test (DUT) - Commercial 5G smartphone or IoT sensor terminal

Network Nodes

• Device Under Test (DUT)
• Hardware RF Channel Emulator
• 3GPP Protocol Conformance Core
• Cryptographic Certification Ledger

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)
