최근 차세대통합네트워크(NGN), ALL-IP 망 진화 방향과 함께 동기식과 비동기식 IMT-2000 망의 통합(Convergence) 또는 연동(Harmonization)에 관한 연구가 활발히 이뤄지고 있으며, 이동통신 망의 개방화에 대한 분위기가 점차 무르익어 가고 있다. 이러한 추세에 UMTS, cdma2000, WLAN 과 같은 서로 다른 방식의 무선 액세스 망으로부터 요구되는 무선인터넷 접속 요구를 하나의 통로로 연결하고 수용할 수 있는 모바일 액세스 통합 게이트웨이가 필요하다. 본 논문에서는 차세대 네트워크 발전 방향과 이동통신 망 개방의 흐름에 맞추어 동기식 망과 비동기식 IMT-2000 망에서 동시에 무선인터넷 서비스 접속을 제공하는 통합 게이트웨이 시스템(A-MiDAS)을 개발하기 위한 형상 설계 방법과 시스템 개발 시 고려사항 등에 대해서 기술한다.
