통신 시장의 경쟁 심화, 급속한 기술 발전은 All-IP 기반의 공통 인프라와 다양한 고품질 융합 서비스의 환경으로 패러다임을 변화시키고 있으며, 이러한 변화에 따라 IP 서비스에 대한 과금 체계 또한 진화하고 있다. 본 고에서는 그 중요성이 증대하고 있는 IP 서비스의 과금 시스템에 대하여 개념과 기술 동향, 관련 표준화 활동을 살펴보고, 차세대 네트워크(BcN)를 대비한 과금 정책에 대하여 기술한다. 그리고 이와 같은 기술 동향 및 과금 정책을 효과적으로 구현하기 위해 ETRI에서 개발중인 고속회선용 정밀과금 시스템을 소개한다.
