본 논문은 네트워크 API(Network API)를 중심으로 통신망의 플랫폼화와 시장 기회를 분석한다. 네트워크 API는 통신사가
보유한 네트워크 기능을 소프트웨어 방식으로 외부에 개방하는 인터페이스로, 통신망을 서비스 실행 플랫폼으로 전환시키
는 핵심 기술이다. 본 연구에서는 GSMA Open Gateway 및 주요 기관의 분석을 종합하여 네트워크 API의 구조와 시장
특성을 도출하였다. 분석 결과, 네트워크 API 시장은 API 자체 매출과 Connectivity+Edge 기반 서비스 매출로 구성되는
이중 수익 구조를 가지며, API 직접 시장은 2030년 기준 6∼12 billion 달러 규모인 반면, Connectivity 및 Edge 기반
서비스 시장은 100∼300 billion 달러 규모로 확대될 것으로 전망된다. 또한 초기 시장은 인증·보안 중심의 Trust API
중심으로 형성되며, 이후 QoS 및 Edge 기반 네트워크 제어 영역으로 확장되는 단계적 성장 구조를 보인다. 본 연구는 네
트워크 API가 통신망의 플랫폼화를 촉진하고, 통신사의 B2B 중심 수익 모델 전환을 이끄는 핵심 수단임을 제시한다.
