1. 1 Global Standards, the Key Enabler for the Next Generation Network David Boswarthick Technical Officer TISPAN david.boswarthick@etsi.org

2. 2 ETSI is …  ICT standards organization, independent & strictly non-profit  Based in Sophia Antipolis, south of France  655+ members from 59 countries  Members are: manufacturers, network operators, service providers, administrations, research bodies and users  80% members have headquarters outside of Europe  ETSI standards are adopted worldwide (e.g. GSM, UMTS, DECT, DVB, TETRA, Lawful Intercept... and many more  ETSI is no longer simply “ European ”  All ETSI standards available for free from our website http://www.etsi.org/http://www.etsi.org/

3. 3 Telecoms networks are getting faster, bandwidth is no longer an issue Telecoms network convergence is inevitable IMS is at the heart of the converged network Main issue is not about networks or technology, the battleground is now on content and services Robust and open global standards are essential to the long term success of the NGN Start with the Conclusions

4. 4 Networks speed increases 10-30 Mbps

5. 5 Why evolve today’s systems?  Considerable investment made in existing telecommunications systems.  Need to ensure the continued competitiveness of these systems for the future.  Strong user demand for innovative services.  Continued demand for cost reduction from both the operator side (CAPEX and OPEX) and from the user side (monthly bill).  Need to keep up with emerging technologies (e.g., Skype, P2P, VoIP).

6. 6 UMTS Before NGN “ Stovepipe” service model Services PLMN PSTN / ISDN Data / IP CATV IMS Core Access GSM/EDGE WiFi/WiMax xDSL PSTN / ISDN Broadcast Content and Services Servers... NGN promises “ simplified” service model

7. 7  3GPP (W-CDMA/UMTS) has established evolution plans which will ensure the future of their technology for the next decade (E-UTRA).  3GPP2 (cdma2000) has established similar plans.  Both projects have incorporated IMS as the basis of their core network.  Variants of OFDM are likely to characterize the air interfaces (at least in the downlink) of both technologies.  These mobile technology streams are converging. OFDM = Orthogonal frequency-division multiplexing Evolution of today’s Mobile systems

8. 8  A number of innovative Broadband Wireless Access (BWA) systems are emerging (e.g., WiMAX, WiBro, WiBree).  They also use variants of OFDM on the air interfaces.  There is growing industrial interest for Mobile and Broadband Wireless Access offerings to co-exist within the same core infrastructure.  These broadband wireless technologies are also converging. WiBro = Korean flavour of WiMax 802.16e WiBree = Nokia enhancement to Bluetooth OFDM = Orthogonal frequency-division multiplexing Evolution of today’s Broadband Wireless Access systems

9. 9  Fixed operators are pursuing IP connectivity as a basis for their future evolution. This work is being driven by ETSI TISPAN.  Cable operators have a similar vision of IMS re-use.  Both Fixed and Cable operators view IMS as the platform for their future systems.  The IMS work is being coordinated by 3GPP.  These fixed technologies are also converging. Evolution of today’s Fixed systems

11. 11 IMS Standards Convergence CableLabs ETSI TISPAN 3GPP 3GPP2 WiMAX Forum IMS “But these standards are prepared in different places” 3GPP

12. 12 Need for a single IMS specification  The requirements for IMS are now derived from a number of different communities (Mobile, BWA, Fixed and Cable).  Risk that IMS could become fragmented.  If IMS variations occur then the economic advantage of the mass market will be lost.  A concerted effort is needed to ensure “one IMS” that meets the needs of all user communities.  The Mobile, BWA, Fixed and Cable industries have recognized this challenge and are working towards a harmonized standardization solution.

13. 13 The current proposal under discussion  The scope of 3GPP should be extended to include the requirements coming from other communities.  A mechanism should be put in place to ensure efficient requirements capture.  3GPP should be responsible for producing one set of IMS specifications that satisfies these requirements.  It is expected that these new arrangements will be put in place during 2007.

14. 14  The ability of systems and products to interwork is fundamental…  Interoperability is  the ultimate aim of our standardisation work  the thread running through the entire standards development process  Interoperability is not an isolated issue  it is not something to be somehow fixed at the end  The best approach  Base standards should be designed with interoperability in mind from the outset  testing (and formal test descriptions) provides vital feedback into the standardization work The importance of Interoperability

15. 15 The need for robust standards  Robust standards are essential for stimulating a multi-vendor, mass market…  …and for future-proofing of investments.  Standardisation requires investment too!

16. 16  ETSI is leading NGN initiatives with …  ETSI is a founding partner of …  ETSI hosts several industry fora who are dealing with NGN services …  ETSI develops test specs/suites …  ETSI runs industry interop. events … ETSI has ‘almost’ all bases covered

17. 17 Conclusions (revisited)  Telecoms network convergence is inevitable  IMS is a pivotal point for NGN success and is the point of convergence.  A single place for IMS specification is essential to ensure that success.  Interoperability testing before implementation in the field is essential  Robust and open global standards are key to the long term success of the NGN
