Abstract

본 발명은 ATM(Asynchronous Transfer Mode) 교환기에 있어서 호 연결 설정 요구시 독립적인 호 처리 기능을 제공할 수있는 프로토콜 처리 및 수행 기능 선택 방법을 테이블 구동 방식에 의하여 수행될 수 있는 ATM 교환기 호 시나리오 추출방법에 관한 것으로, 호 시나리오를 추출하는 방법은 호 처리 기능을 여러 종류의 프로토콜과 독립적으로 둘 수 있게 함으로서 각 시나리오를 구성하고 있는 기능 조각들을 효율적으로 제어할 수 있는 호 제어 엔진 테이블(TRCT)이 부가될 경우에 소프트웨어 재사용성을 중대시킬 수 있고 미확장 기능을 시스템에 추후 첨가할 경우에도 구현된 시스템에 영향을 최소로 하고 구현할 수 있는 효과가 있다.The present invention provides a method for extracting an ATM switch call scenario that can be performed by a table driving method for selecting a protocol processing and execution function that can provide an independent call processing function when a call connection establishment request is made in an ATM (Asynchronous Transfer Mode) exchange. The method for extracting a call scenario is to add a call control engine table (TRCT) that can efficiently control the pieces of functionality constituting each scenario by allowing call processing functions to be independent of various protocols. In this case, software reusability can be greatly increased, and the addition of an unexpanded function to the system later can have the effect of minimizing and implementing the implemented system.
