Summary:Provided is a method for configuring a static port in a Time Sensitive Networking Application Function (TSN AF) of a system that operates as a TSN bridge. The method for configuring a static port comprises the steps of: determining a grandmaster clock according to requirements; configuring a time synchronization spanning tree having the grandmaster clock as a root; and determining port states of a Device side TSN Translator (DS-TT) and a Network side (NW)-TT through role determination of the DS-TT and NW-TT, which operate as terminal-side bridge ports in the system. According to the present invention, it is possible to reduce signaling overhead in a 5G system for a separate BMCA operation. TSN(Time Sensitive Networking) 브릿지로 동작하는 시스템의 TSN AF(Application Function)에서의 정적 포트 구성 방법이 제공된다. 정적 포트 구성 방법은 수신한 요구사항에 따라 그랜드 마스터 클럭을 결정하고, 상기 그랜드 마스터 클럭을 루트로 하는 시간동기화 스패닝 트리를 구성하며, 상기 시스템에서 단말측 브릿지 포트로 동작하는 DS-TT(Device side TSN Translator)와 네트워크측 브릿지 포트로 동작하는 NW(Network side)-TT의 역할 결정을 통해 상기 DS-TT와 상기 NW-TT의 포트 상태를 결정한다.
