Objectives :

The coursework introduces students to Next Generation Services (NGN) and communication services, with a focus on Service architectures. The course describes in detail how communication services are conceived, developed and deployed in wireline and wireless networks.

The course concentrates on NGN architectures and the convergence of telco and web. The courses also address future evolutions (e.g. IMS-based IPTV, OTT, Telco 2.0) that will significantly change the telecommunication industry worldwide with the replacement of today’s networks.

The course also cover today’s networks, to allow the students understand the changes that the world of telecommunications and internet is facing. Message flows and procedures are thoroughly examined in class and in small student groups to strengthen understanding. CAMEL-based service architectures, IMS/NGN service architectures are particularly emphasized. The course also introduces the alternatives to operator-centric architectures to provide communication services to the users. Other approaches such as Peer-to-Peer systems, OTT, web-NGN convergence, user generated services are introduced.

With the emergence of the Internet-of-Things, everything is becoming connected, and so networks have evolved from primarily a source of information to the most important platform for many types of applications, involving all kinds of devices and objects. The basic of the Internet of Things and its potential of disruption will be presented.

In addition, the principles of the main social Networks and their role in today’s ecosystem are presented.
