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 freefrom our website http://www.etsi.org/

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

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).

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
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 802.16eWiBree = Nokia enhancement to Bluetooth
OFDM = Orthogonal frequency-division multiplexing

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.

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
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.

The ability of systems and products to interwork is fundamental…
Interoperability is the ultimate aim of our standardisation workthe thread running through the entire standards development processInteroperability is not an isolated issueit is not something to be somehow fixed at the end
The best approachBase standards should be designed with interoperability in mind from the outsettesting (and formal test descriptions) provides vital feedback into the standardization work
The importance of Interoperability
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!

ETSI has ‘almost’ all bases covered
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
