A FUNCTIONAL TESTING APPROACH FOR INTERWORKING BETWEEN CCS7 TUP AND NON-CCS7 SIGNALING SYSTEMS

摘要

This paper focuses on the interworking problem between CCS7 TUP (Telephone User Part) and non-CCS7 signaling systems.It presents a novel functional testing approach to verify proper interworking of CCS7 TUP and other non-CCS7 signaling systems in a switching system.Basically,the problem of signaling interworking on a telephone switch is abstracted into functional categories.These categories are used to derive the tests that are crucial in assuring the correcmess of signaling interworking in a switching system.It is found that the complex task of testing signaling interworking for a switching system becomes much easier to tackle through such a functional testing approach.
