Provided are an apparatus and method for testing call processing performance and conformance of a media gateway controller and a media gateway with respect to a media gateway control (MEGACO) protocol. The method includes generating a predetermined scenario regarding a test of call processing performance of a media gateway controller or a media gateway; selecting a function of the media gateway controller or the media gateway and emulating virtual analog lines between the media gateway controller and the media gateway according to the scenario; and testing the call processing performance of the media gateway controller or the media gateway using the virtual analog lines and the selected media gateway controller or the media gateway. Accordingly, it is possible to effectively test the call processing performance of the media gateway controller or a media gateway without test equipment.

Apparatus and method for testing MEGACO protocol

An improved rare probability connection call registration method which utilizes automatic congestion level (ACL) information within a release message for an asynchronous transfer mode (ATM) switching system. The method includes the steps of setting a predetermined threshold value, receiving a call releasing message, checking automatic congestion level (ACL) information in the call release message, and determining whether an ACL information is set. When the ACL information is not set continuous checks are made, and the method continues by increasing the count value when the ACL information is set, and it is determined whether the value of the ACL counter is greater than a predetermined threshold value. The method continues by registering a corresponding code as a rare probability connection call (RPCC) when the value of the counter is greater than the threshold value, outputting the corresponding code to an operator through an operator terminal, requesting call control with respect to the call request which is routed to the corresponding route, and clearing the value of the counter when the value of the counter is less than the threshold value after the measurement unit time has passed.
