ICT Convergence: Modeling IssuesRolv Bræk1and Jacqueline Floch21Department of Telematics,Norwegian University of Science and Technology,NO-7491 Trondheim, Norwayrolv. braek@item. ntnu. no2SINTEF ICT, NO-7465 Trondheim, Norwayjacqueline. floch@sintef. noAbstract. Even though ICT convergence is a well-established and a-dopted concept, there is no consensus about the underlying softwareengineering approach to convergent ICT systems. Telecom engineers andsoftware engineers traditionally use different approaches when develop-ing services and applications. A main question is whether or not thedifferences are justified and should be maintained in the context of con-vergence? In this paper, we seek to answer this question by analyzingthe different nature of the telecom domain and the computing domain.We identify a few fundamental differences that must be bridged whenmaking convergent systems and we investigate how UML can be used asan enabler to build such bridges.1IntroductionSince the introduction of software for the control of switching systems in the1960s, telecommunication systems have increasingly depended on software. Theseparation between networks and services initiated by IN [12, 13] and continuedwith Parlay/OSA is a significant development in the telecommunication history.This separation, combined with general Internet access, has enabled services thatintegrate and combine traditional communication services with information ser-vices in innovative ways. It has also opened the network for third-party serviceproviders (at least in principle). Such novel services encompass much more thanconnectivity. Users being exposed to computers and Internet have increasinglygrown to expect more. As a result, service engineering is no longer limited to con-nectivity services, but will have to deal with a rich range of advanced applicationoriented services.Beyond access to network resources through Parlay/OSA interfaces, there isno consensus in the telecommunication industry on what future service archi-tectures will look like and which principles they should build upon. TINA [11]Both authors have contributed equally to this paper. Author names are listed inalphabetic order.D. Amyot and A.W.
