이동 망 및 인터넷의 폭발적인 확장과 망 통합의 가속화에 따라 다양한 서비스 기능 및 데이터의 결합이 필수적인 서비스가 요구되고 있으나, 기존의 지능 망 기반 구조로는 이러한 서비스에 대한 대처하기가 현실적으로 불가능하다 이에 대한 해결책으로써 국제 표준화 포럼인 Parlay 를 중심으로 개방형 기술 기반의 서비스 API(Application Programming interface)를 개발해 오고 있다. 본 논문에서는 개방형 서비스 API 의 표준 규격인 Parlay/OSA API 구조에 대해서 살펴본다. IP 기반의 통합 망에서의 본 API 적용을 위한 망 구조를 제시하고, 실제 서비스 예를 대상으로 망 내각 노드 간의 처리 흐름 및 Parlay/OSA API와 망 내 신호 방식간 연동방법 등을 제안하였다.
