초록

5G는 2020년 이후를 위한 4G 다음 세대의 이동통신으로 검토가 시작되었으나, 이동통신의 연장선이 아닌 이동통신과 네트워크의 새로운 패러다임으로 인식되고 있다. 5G는 이동통신, 인터넷, 클라우드가 통합되는 네트워크 + IT 환경이 될 것이며, 기술, 서비스, 타 산업과의 관계, 시장, 사업구도 등 모든 면에서 새로운 변화가 예상된다. 본고에서는 2016년을 기점으로 본격화될 5G의 아키텍처에 대한 최근 연구동향을 정리한다. 아키텍처의 범위는 Radio Access Network(RAN) 아키텍처, 코어네트워크 아키텍처, 가상화/프로그래머블 아키텍처, 네트워크 관리 자동화/지능화 아키텍처 등이다. 주요 연구프로젝트, 통신사업자, 산업체 등에서 제안한 5G 아키텍처 현안들을 각각 정리한다.
