FlexibleAirspace：空域柔軟利用（FUA）＆軍民動的空域リザーブ統合制御

FlexibleAirspaceはFUAプロトコルを自動化し、軍事演習終了と同時に特別使用空域（SUA/TRA）を民間航空機へ即座に開放して飛行時間と燃料を大幅に削減します。

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)
