최근 국가 경제발전을 위해 초광대역망에 투자하는 것이 국제적인 추세이며 PSTN 기반 음성서비스에서 초광대역망을 기반으로 VoIP 서비스로 급속히 옮겨가고 있다. 이로 인해 PSTN 음성서비스 트래픽이 감소하고 VoIP 서비스의 이용은 증가하고 있으며 유선상호접속제도에 큰 변화를 주고 있다. 상호접속을 위한 망 구조에서부터, 망 기술, 접속점, 비용산정방식 등 새롭게 논의해야할 과제들이다. 본 연구에서는 NGN 하에서 유선상호접속제도에 대해 논의한 바 있는 유럽 주요국(오스트리아, 벨기에, 덴마크, 프랑스, 독일, 네덜란드, 노르웨이, 스웨덴)을 대상으로 NGN 하에서 유선접속료제도의 과제들에 대한 각국의 입장을 정리하였다. 또한 PSTN 기반 상호접속제도에서 NGN 기반으로 진화하는 과정을 살펴봄으로써 국내 IP-LRIC 유선상호접속료 산정모델 개발을 위한 주요 검토과제를 제시하였다.
