    1. 1. Global Standards, the Key Enabler for the Next Generation Network David Boswarthick Technical Officer TISPAN [email_address]
    2. 2. ETSI is … <ul><li>ICT standards organization, independent & strictly non-profit </li></ul><ul><li>Based in Sophia Antipolis, south of France </li></ul><ul><li>655+ members from 59 countries </li></ul><ul><li>Members are: manufacturers, network operators, service providers, administrations, research bodies and users </li></ul><ul><li>80% members have headquarters outside of Europe </li></ul><ul><li>ETSI standards are adopted worldwide (e.g. GSM, UMTS, DECT, DVB, TETRA, Lawful Intercept ... and many more </li></ul><ul><li>ETSI is no longer simply “European” </li></ul><ul><li>All ETSI standards available for free from our website http:// www.etsi.org / </li></ul>
    3. 3. <ul><li>Telecoms networks are getting faster, bandwidth is no longer an issue </li></ul><ul><li>Telecoms network convergence is inevitable </li></ul><ul><li>IMS is at the heart of the converged network </li></ul><ul><li>Main issue is not about networks or technology, the battleground is now on content and services </li></ul><ul><li>Robust and open global standards are essential to the long term success of the NGN </li></ul>Start with the Conclusions
    4. 4. Networks speed increases 10-30 Mbps
    5. 5. Why evolve today’s systems? <ul><li>Considerable investment made in existing telecommunications systems. </li></ul><ul><li>Need to ensure the continued competitiveness of these systems for the future. </li></ul><ul><li>Strong user demand for innovative services. </li></ul><ul><li>Continued demand for cost reduction from both the operator side (CAPEX and OPEX) and from the user side (monthly bill). </li></ul><ul><li>Need to keep up with emerging technologies (e.g., Skype, P2P, VoIP). </li></ul>
    6. 6. UMTS Before NGN “ Stovepipe” service model Services Services Services Services PLMN PSTN / ISDN Data / IP CATV IMS Core Access Access Access GSM/EDGE WiFi/WiMax xDSL PSTN / ISDN Broadcast MGWs Content and Services Servers ... NGN promises “ simplified” service model
    7. 7. <ul><li>3GPP (W-CDMA/UMTS) has established evolution plans which will ensure the future of their technology for the next decade (E-UTRA). </li></ul><ul><li>3GPP2 (cdma2000) has established similar plans. </li></ul><ul><li>Both projects have incorporated IMS as the basis of their core network. </li></ul><ul><li>Variants of OFDM are likely to characterize the air interfaces (at least in the downlink) of both technologies. </li></ul><ul><li>These mobile technology streams are converging. </li></ul><ul><li>OFDM = Orthogonal frequency-division multiplexing </li></ul>Evolution of today’s Mobile systems
    8. 8. <ul><li>A number of innovative Broadband Wireless Access (BWA) systems are emerging (e.g., WiMAX, WiBro, WiBree). </li></ul><ul><li>They also use variants of OFDM on the air interfaces. </li></ul><ul><li>There is growing industrial interest for Mobile and Broadband Wireless Access offerings to co-exist within the same core infrastructure. </li></ul><ul><li>These broadband wireless technologies are also converging. </li></ul><ul><li>WiBro = Korean flavour of WiMax 802.16e WiBree = Nokia enhancement to Bluetooth OFDM = Orthogonal frequency-division multiplexing </li></ul>Evolution of today’s Broadband Wireless Access systems
    9. 9. <ul><li>Fixed operators are pursuing IP connectivity as a basis for their future evolution. This work is being driven by ETSI TISPAN. </li></ul><ul><li>Cable operators have a similar vision of IMS re-use. </li></ul><ul><li>Both Fixed and Cable operators view IMS as the platform for their future systems. </li></ul><ul><li>The IMS work is being coordinated by 3GPP. </li></ul><ul><li>These fixed technologies are also converging. </li></ul>Evolution of today’s Fixed systems
    10. 10. IMS Technology Convergence Cable Fixed Mobile Broadband Wireless Access “ IMS has become the point of convergence” IMS
    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 <ul><li>The requirements for IMS are now derived from a number of different communities (Mobile, BWA, Fixed and Cable). </li></ul><ul><li>Risk that IMS could become fragmented. </li></ul><ul><li>If IMS variations occur then the economic advantage of the mass market will be lost. </li></ul><ul><li>A concerted effort is needed to ensure “one IMS” that meets the needs of all user communities. </li></ul><ul><li>The Mobile, BWA, Fixed and Cable industries have recognized this challenge and are working towards a harmonized standardization solution. </li></ul>
    13. 13. The current proposal under discussion <ul><li>The scope of 3GPP should be extended to include the requirements coming from other communities. </li></ul><ul><li>A mechanism should be put in place to ensure efficient requirements capture. </li></ul><ul><li>3GPP should be responsible for producing one set of IMS specifications that satisfies these requirements. </li></ul><ul><li>It is expected that these new arrangements will be put in place during 2007. </li></ul>
    14. 14. <ul><li>The ability of systems and products to interwork is fundamental… </li></ul><ul><li>Interoperability is </li></ul><ul><ul><li>the ultimate aim of our standardisation work </li></ul></ul><ul><ul><li>the thread running through the entire standards development process </li></ul></ul><ul><ul><li>Interoperability is not an isolated issue </li></ul></ul><ul><ul><li>it is not something to be somehow fixed at the end </li></ul></ul><ul><li>The best approach </li></ul><ul><ul><li>Base standards should be designed with interoperability in mind from the outset </li></ul></ul><ul><ul><li>testing (and formal test descriptions) provides vital feedback into the standardization work </li></ul></ul>The importance of Interoperability
    15. 15. The need for robust standards <ul><li>Robust standards are essential for stimulating a multi-vendor, mass market… </li></ul><ul><li>… and for future-proofing of investments. </li></ul><ul><li>Standardisation requires investment too ! </li></ul>
    16. 16. <ul><li>ETSI is leading NGN initiatives with … </li></ul><ul><li>ETSI is a founding partner of … </li></ul><ul><li>ETSI hosts several industry fora who are dealing with NGN services … </li></ul><ul><li>ETSI develops test specs/suites … </li></ul><ul><li>ETSI runs industry interop. events … </li></ul>ETSI has ‘almost’ all bases covered
    17. 17. Conclusions (revisited) <ul><li>Telecoms network convergence is inevitable </li></ul><ul><li>IMS is a pivotal point for NGN success and is the point of convergence. </li></ul><ul><li>A single place for IMS specification is essential to ensure that success. </li></ul><ul><li>Interoperability testing before implementation in the field is essential </li></ul><ul><li>Robust and open global standards are key to the long term success of the NGN </li></ul>
