NTNPhone: 위성 연결 지원 스마트폰 시스템 및 초저비트레이트 음성 코덱

NTNPhone은 위성 직결 스마트폰을 위한 OS API 및 초저대역폭 보코더 표준을 정의하여 전 세계 어디서나 선명한 위성 통화와 SOS 메시징을 지원합니다.

NTNPhone Satellite Voice & SOS Operating System Architecture

Native operating system integration managing RF pointing guides and low-rate vocoding

Central System: Native AR Sky Guide UI - Augmented reality compass guiding user to overhead LEO satellite

Network Nodes

  • Native AR Sky Guide UI
  • Enhanced Voice Services (EVS) Engine
  • SOS Emergency Protocol Daemon
  • 3GPP NTN S-Band Transceiver

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)
