Abstract

본 발명은 ATM 망으로부터 신호적응계층을 통해 수신된 메세지를 메모리에 저장한 후 카운터를 이용하여 상기 셋업 메세지에 저장된 원인(Cause) 정보요소를 찾아 원인값(Cause Value) 정보를 식별하기 위한 방법에 관한 것으로, 상기 수신된 메세지의 길이 정보(Ls)를 구하는 제1단계; 상기 카운터의 카운트값을 증가시키면서 "8₁₀"과 비교하여 Cause 정보요소를 구하는 제2단계; 상기 카운터값이 상기 메세지 길이를 초과하는지 비교하여 에러를 검출하는 제3단계; 및 상기 Cause 정보요소로부터 원인값(Cause Value)을 독출하여 출력하는 제4단계를 구비한다.The present invention relates to a method for identifying cause value information by storing a message received through a signal adaptation layer from an ATM network in a memory and using a counter to find a cause information element stored in the setup message. And a first step of obtaining length information Ls of the received message; A second step of obtaining a Cause information element compared with " 8 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 a fourth step of reading and outputting a Cause Value from the Cause information element.

Claims

A method for identifying a cause value information by storing a message received through a signal adaptation layer from an ATM network in a memory and using a counter to find a cause information element stored in the setup message. Obtaining a length information Ls of the received message; A second step of obtaining a Cause information element compared with " 8 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 a fourth step of reading out and outputting a cause value from the Cause information element.
