Telekommunikationstjenester

• Describe the mechanisms and interactions involved in multimedia transmission over IP and analyze requirements for specific applications, in terms of scalability and other.
• Apply the previous abilities to design architectures allowing streaming-based services.
• Describe the characteristics on main VoIP signalling protocols/architectures (SIP vs H323) and analyze SIP & H323 behaviour, based on experimentation and traffic analysis.
• Infer similarities and differences of basic SIP-based architectures vs complex ones, i.e. UMTS’s Internet Multimedia Subsystem (IMS).
• Describe the requirements for interoperation of conventional telephony (PSTN/SS7) architectures, with VoIP-based ones, for basic voice services as well as for supplementary services (i.e. IN).
• Apply the previous abilities to analyse service requirements and to design adequate architectures allowing the provision of telephony services in hybrid and/or converged telephony networks.
• Organize, plan and carry out collaborative work in group projects

The course addresses emerging telecommunication services and network architectures with a strictly technological focus and leaves market, business and regulation aspects out of consideration. Initially the focus is on current IP-based commercial telecom-related services such as multimedia streaming, voice over IP, IP telephony and the Internet Multimedia Subsystem (IMS) for UMTS. This continues to protocols and architectures for providing hybrid and converged voice based services and Next Generation Networks (NGN). Finally platforms and architectures for service development and provision in a converged, IP based network are discussed.
The course is designed also to address generic competences such as communication skills, ability to think critically and creatively, drive to work with open problems, team work, control of self and group learning, self confidence and adaptability to demanding and changing environments.

Lectures, problems, laboratory exercises and group work with peer coaching and teacher mentoring. Role-game based.

Working teams will be formed during the first week of the course, so students not attending the course during that week will be considered as dropping the course.

This course is suitable as part of a Ph.D. study plan.
