Abstract
Service modelling has become an increasingly important area in today's telecommunications and information systems practice. We have adapted a Network Design course in order to teach service modelling to a mixed class of both the telecommunication engineering and information systems backgrounds. An integrated approach engaging mathematics teaching with strategies such as problem-solving, visualization, and the use of examples and simulations, has been developed. From assessment on student learning outcomes, it is indicated that the proposed course delivery approach succeeded in bringing out comparable and satisfactory performance from students of different educational backgrounds.

From the Internet to pervasive mobile computing, the recent decades have witnessed unprecedented, rapid technology evolutions
We show that by simple mathematical derivation one can work out the solutions for such a queueing system
To evaluate the effectiveness of our delivery approach, especially how well it addresses the class diversity, first we compare the performance of the two groups of students (IS and TELE) across three assessments: the queueing assignment (‘QT’), the design project (‘Project’), and the final exam (‘Exam’)
Summary
From the Internet to pervasive mobile computing, the recent decades have witnessed unprecedented, rapid technology evolutions. The fast advance of various technologies, ranging from optical fibre, Wi-Fi, satellites, 3G and 4G, to ultra-wide band, near-field communications, RFID, wireless sensor networks, and cloud computing, poses challenges of many technological dimensions that a telecommunication carrier or an enterprise client needs to cope with. Amid the increasing technical complexity, there is a growing “convergence” of modern information technology and telecommunications, and next-generation networking and computing are becoming more and more service oriented (Price, 2009). Service engineering has become an important notion that is useful for better design, planning, operation, and maintenance of various ICT services. There remains a lack of sufficient attention paid to the service modelling aspect of telecommunication engineering.
