Abstract

본 발명은 ATM 망으로부터 신호적응계층를 통해 수신된 메세지를 메모리에 저장한 후 카운터를 이용하여 상기 메세지에 저장된 발신자번호(Calling Party Number) 정보요소를 찾아 어드레스/넘버 디짓을 식별하기 위한 방법에 있어서, 상기 메세지의 길이 정보(Ls)를 구하는 제1단계; 상기 카운터의 카운트값을 증가시키면서 "10810"과 비교하여 발신자번호(Calling Party Number) 정보요소를 구하는 제2단계; 상기 카운터값이 상기 메세지 길이를 초과하는지 비교하여 에러를 검출하는 제3단계; 및 상기 발신자번호(Calling Party Number) 정보요소로부터 정보요소의 제5옥텟을 읽어와 번호 타입이 "16"이고 어드레싱/넘버링 플랜이 "1"이며, 확장자가 0이면 카운터의 값을 2증가시킨 후, 확장자가 1이면 카운터의 값을 1증가시킨 후 소정의 어드레스/넘버 디짓을 독출하여 출력하는 제4단계를 구비한다.The present invention relates to a method for identifying an address / number digit by storing a message received through a signal adaptation layer from an ATM network in a memory and using a counter to find a Calling Party Number information element stored in the message. A first step of obtaining length information Ls of the message; Obtaining a Calling Party Number information element by comparing with " 108 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; And reading the fifth octet of the information element from the Calling Party Number information element, increasing the value of the counter by 2 if the number type is "16" and the addressing / numbering plan is "1" and the extension is 0. And a fourth step of increasing the value of the counter by 1 if the extension is 1, and then reading and outputting a predetermined address / number digit.
