컴퓨터 수준의 스마트 디바이스를 이용하는 현재의 이동통신 환경은 처리해야 할 정보량의 급속한 증가에 효율적으로 대응하기 위해서 새로운 시스템 및 네트워크 구조와 기술들을 연구개발하고 있고 여러 가지 후보 기술 중 대규모 고밀도 액세스 네트워크(UDN) 구조 연구에 대한 관심이 높아지고 있다. UDN 환경의 CAPEX 및 OPEX 문제를 해결하기 위해서 최근 액세스 네트워크의 공유 방안에 대한 논의 및 표준화가 진행되어 기술적으로는 인터넷 환경에서 검증된 가상화 기술의 액세스 네트워크 적용을 추진하고 있다. 이러한 동향을 반영하여 최근 SCF 주도로 완성된 소형 셀 기지국 가상화 규격이 현실적이고 실질적인 연구 결과로 평가되어 세부 사항을 분석한다.
