Abstract

The Single TTCN has been broadly used to describe the ATS(Abstract Test Suite) for the protocol confronance testing. But if the single TTCN is used to test the multi-party protocol with the non-deterministic factors, then huge amount of test notations are needed and also it is hard to understand the ATS. Therefore, the concurrent TTCN was proposed to solve these problems and the study in progress. In this paper, we did investigate and compare the characteristics of esisting single TTCN with those of the concurrent TTCN. In order to develop the ATS of the Q.2971 which is B-ISDN call/connection control protocol, the testing model was defined and the concurrent factors were extracted according to that model. As a result, we could verify the usefulness of the confcurrent TTCN.
