Creating telecommunication services based on object-oriented frameworks and SDL

Abstract

The paper describes the tools and techniques being applied in the TINA Open Service Creation Architecture (TOSCA) project to develop object oriented models of distributed telecommunication services in SDL. The paper also describes the way in which Tree and Tabular Combined Notation (TTCN) test cases are derived from these models and subsequently executed against the CORBA based implementations of these services through a TTCN/CORBA gateway.
