Abstract

본 발명은 ATM망으로부터 신호적응계층을 통해 수신된 메세지를 메모리에 저장한 후 카운터를 이용하여 상기 메세지에 저장된 착신자번호(Called Party Number) 정보요소를 찾아 NSAP 어드레스 옥텟을 식별하기 위한 방법에 관한 것으로, 상기 메세지의 길이 정보(Ls)를 구하는 제1단계; 상기 카운터의 카운트값을 증가시키면서 "11210"와 비교하여 착신자번호(Called Party Number) 정보요소를 구하는 제2단계; 상기 카운터값이 상기 메세지 길이를 초과하는지 비교하여 에러를 검출하는 제3단계 및 상기 착신자번호(Called Party Number) 정보요소로부터 정보요소의 제5옥텟을 읽어와 번호 타입이 "0"이고 어드레싱/넘버링 플랜지 "2"이면, 제6옥텟부터 소정의 NSAP 어드레스 옥텟을 독출하여 출력하는 제4단계를 구비한다.The present invention relates to a method for identifying a NSAP address octet by storing a message received through a signal adaptation layer from an ATM network in a memory and using a counter to find a Called Party Number information element stored in the message. A first step of obtaining length information Ls of the message; Obtaining a Called Party Number information element by comparing it with " 112 10 " while increasing the count value of the counter; A third step of detecting an error by comparing the counter value exceeding the message length and reading a fifth octet of the information element from the called party number information element, and having a number type of " 0 " and addressing / numbering If the flange is "2", a fourth step of reading and outputting a predetermined NSAP address octet from the sixth octet is provided.
