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/

Start with the Conclusions
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).

Evolution of today’s Mobile systems
 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
7
Evolution of today’s Broadband Wireless
Access systems
 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
8
Evolution of today’s Fixed systems
 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.
12
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.
13
The importance of Interoperability
 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
14
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!
15
ETSI has ‘almost’ all bases covered
 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 …
16
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
