5G 네트워크 기술은 4G LTE 이동 통신 기술의 후속 기술로서, ITU-R, ITU-T, NGMN, 3GPP 등의 표준화 그룹을 중심으로 고성능, 저지연, 고가용성 등의 특성을 가지는 새로운 Clean-slate 형태의 이동 통신 시스템 및 네트워크 구조를 설계 중이다. 특히 다양한 5G 융합 서비스를 효율적으로 제공하기 위해 서비스 및 네트워크 자원의 독립성 및 유연성을 지향하는 네트워크 슬라이싱을 적용하고, ETSI NFV 네트워크 기능 가상화 기술을 포함하는 네트워크 관리 구조를 도입하고자 한다. 본고에서는 5G 네트워크 슬라이싱 기술 및 5G 네트워크 관리 기술의 개념 및 요구사항을 분석하고, 이에 대해 3GPP SA WG2 및 SA WG5에서 진행 중인 표준화 현황을 소개한다.
