S-38.130 Licentiate course on Telecommunications Technology
Presentation Topics
References to Chapters 1...7 point to "IP Telephony" by Olivier Hersent
et al. This book gives us the overall outline of the course. Some of the
topics, however, go much farther than the book and are small scale research
projects in their own right.
The
current assignement of topics to students is here.
-
1. Overall picture of IP Telephony (Chapter 1 + specs + other
- specifics of H.323)
-
2. H.323 protocol suite (Chapter 1 pgs 20 ...102 + specs +
other)
-
3. Voice in packets: RTP, RTCP, header compression, playout
algorithms, terminal requirements and
implementations
-
4. Session Initiation Protocol (SIP) ( Chapter 2 + specs +
other)
-
5. Session Initiation Protocol in 3G (3G PP material + Kati
Ahvonen's Diploma thesis)
-
6. Comparison of SIP and H.323
-
7. Master-Slave protocols: Megaco, H.248, MGCP (Chapter 3 +
specs + other )
-
8. Voice Quality, E-model, other models, quality measurements
(Chapter 4 + E-model + other)
-
9. Voice Coding (Chapter 5 + specs + other)
-
10. Voice quality and coding in packet based 3G (material ?)
-
11. Network dimensioning (Chapter 7 + other)
-
12. Telephony Routing Information Protocol, ENUM, Number portability
(specs )
-
13. Review of IP Telephony research directions (IP Telephony workshop,
Berlin)
-
14. Review of standardisation efforts (IETF, Tiphon, 3 GPP, etc ...)
-
15. Review of IP Telephony Business today and evaluation of the long term
impact
-
16. Voice over ATM, Voice over ADSL, Voice over CableTV
-
17. Security and IP Telephony
-
18. IP Telephony services: CGI, SIPlets, Application servers, IN/CAMEL,
Parlay, H.323 supplementary
services.
-
19. Interworking of IP Telephony with legacy networks.
-
20. ISUP over IP, SIGTRAN work review.
You may suggest your own topic. It should, however, be closely related
to the scope of the course, not overlap too much with other topics and
the presentation paper on this topic should naturally meet the requisites
of the course.
