Diagnosis information control method to support interoperability in case of protocol error in application layer protocol using Q amp; A application

摘要

The present invention relates to a method for controlling diagnostic information in which an application layer protocol (ALP) notifies the other node of an error when an error occurs in an application layer protocol (ALP) using a question-and-answer function application unit (TCAP). When a protocol error occurs to facilitate modification or supplementation of the TCAF user protocol by providing a method of accurately notifying the other node of performing its own protocol function in order to recognize the difference in implementation easily and quickly. A first step (1, 2) of encoding diagnostic information according to each type of error; A second step (3) of transmitting the related information to the counterpart node; A third step (4) of mutually checking an error in an encoding / decoding process in a TCAP user protocol according to the diagnostic information; And a fourth step (5, 6) of correcting / complementing the protocol at the node that caused the protocol error, so that the point of occurrence of the protocol error can be accurately identified, detailed differences in information can be identified, and It is effective to provide detailed data for high quality network operation.
