5G 이동통신의 주요 서비스 시나리오 중 고신뢰 및 초저지연통신(URLLC)은 산업용 자동화, 의료용 로봇 제어, 자율 주행과 같이 빠른 응답시간과 고가용성을 요구한다. URLLC의 요구 조건을 만족하기 위해 유럽 통신 표준 협회는 모바일 에지 컴퓨팅(MEC) 기술을 표준화하고 있으며, 한국전자통신연구원에서는 MEC 표준을 준수하는 MEC 플랫폼을 개발하고 있다. 본고에서는 최근 이슈가 되고 있는 디지털 트윈 패러다임에 대해 알아보고, 디지털 트윈이 URLLC 서비스에 제공할 수 있는 이점들에 대해 살펴본다. 그리고 URLLC 서비스의 사이클 시간 단축을 위해 한국전자통신연구원 MEC 플랫폼에서 제공하는 디지털 트윈 서비스(DTS)에 대해 설명한다.
