NTNReady：3GPP Rel-17/18 NTN商用レディネス認証＆キャリア検証プログラム

NTNReadyは、自動コンプライアンス試験スイートとOTAチャネルシミュレータを提供し、商用端末、チップセット、基地局が3GPP NTN仕様に完全準拠していることを公式認定します。

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)
