Communication Services and All-Web convergence


The conception and deployment of services is a key challenge for the telecom market. Services should fundamentally be tailored to user preferences, rely seamlessly on multiple access networks and bundle multiple service features (e.g. voice/video, social networks, presence, gaming and IPTV). This course will introduce services from legacy Intelligent Network, to IMS and web-based communication services. We will also present the actual challenges for communication services and evolution of the service architecture from telco 1.0 to current/future telco 2.0 with the openness of the operator’s network and assts to third parties though APIs.  P2P systems will also be presented.


The coursework introduces students to Next Generation 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 (Next Generation Networks) architectures. The courses also address the webification of services (from the IMS to OTT solutions) 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, web-NGN convergence, Social Networks, Cloud, are introduced.
