본 논문은 GSO 위성 환경에서 IoT-NTN 을 이용한 음성서비스 제공을 위해서 3GPP 에서
진행중인 표준화 작업 내용을 소개한다. 기본적으로 LTE 에서 음성서비스를 제공하기 위해
도입된 기술을 바탕으로 하고 있지만, 지상 네트워크(Terrestrial Network) 환경보다 많은
제약을 가지고 있는 비지상 네트워크(Non Terrestrial Network) 환경과 매우 낮은 전송속도를
지원하는 IoT 전송기술로 음성서비스를 지원하기 위해서는 기존의 방식에서 수정되어야 하는
부분들이 있다. 특히 GSO 환경은 매우 긴 전파지연시간을 가지기 때문에, 이를 고려한
SPS(Semi Persistent Scheduling)을 적용하는 방식 및 그에 따라 영향을 받는 부분들에 대한
논의가 집중적으로 이루어지고 있다.
