Abstract

본 발명은 ATM망으로부터 신호적응계층을 통해 수신된 상태(STATUS) 메세지를 메모리에 저장한 후 카운터를 이용하여 상기 메세지에 저장된 호상태(call state) 정보요소를 찾아 호 상태 값 및 전역 인터페이스 값(CG : Call State Value/Global Interface Value)을 식별하기 위한 방법에 관한 것으로, 상기 상태 메시지의 길이 정보(Ls)를 구하는 제1단계; 상기 카운터의 카운트값을 증가시키면서“2010”과 비교하여 호 상태(Call state)정보요소를 구하는 제2단계; 상기 카운터값이상기 메세지 길이를 초과하는지 비교하여 에러를 검출하는 제3단계; 상기 호 상태 정보요소로부터 호 상태 값 및 전역 인터페이스 값(CG : Call State Value/ Global Interface Value)을 독출하는 제4단계; 상기 제4단계에서 독출한 데이타가“1,3,6,8,9,10,11, 또는 12”이면 호 상태값을 출력하고,“61 또는 62”이면 전역 인터페이스 상태값을 출력하고, “0”이면전역(global)인지를 판단하여 상태값을 판단하여 출력하는 제5단계를 구비한다.The present invention stores a state message received from the ATM network through the signal adaptation layer in a memory and finds a call state information element stored in the message by using a counter. CG: a method for identifying a call state value / global interface value, comprising: a first step of obtaining length information Ls of the status message; A second step of obtaining a call state information element compared with "20 10 " while increasing the count value of the counter; A third step of detecting an error by comparing whether the counter value exceeds the message length; A fourth step of reading a call state value and a global interface value (CG) from the call state information element; If the data read out in the fourth step is "1, 3, 6, 8, 9, 10, 11, or 12", the call state value is output; if "61 or 62", the global interface state value is output, And a fifth step of determining whether or not it is global and determining and outputting a state value.
