ETSI is

• ICT standards organization, independent
  strictly non-profit
• Based in Sophia Antipolis, south of France
• 654 members from 61 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 standards can no longer be considered as
  simply European
• All ETSI standards available for freefrom our
  website http//www.etsi.org/

The times they are a changin
The order is rapidly fadin'.And the first one
now will later be last For the times they are
a-changin'. lt Bob Dylan 1965 gt

• Ericsson buys Marconi Ericsson is paying 1.2bn
  for the name and most of the assets of Marconi
  (Oct 05)
• eBay buys Skype for 4.1 Billion (June 05)
• Lucent and Alcatel to merge and form a new
  communication solutions provider (April 06)
• Juniper and NEC announce plans for joint FMC
  solutions (Nov 06)
• Nokia Siemens Networks a 50-50 joint venture
  that will cover both fixed line and mobile
  networks (June 06)
• Google acquire YouTube for 1.65 Billion (Oct
  06)
• 3Com bid for Huawei assets in H3C (Nov 06)
• Others in the pipe ??? Media buzz around Nortel,
  Cisco, Motorola, Ericsson ???

Operators feel the squeeze

• Market competition is increasing
• Incumbents squeeze incumbents (internationally)
• Mobile operators squeeze fixed operators
• Fixed operators fight back with Wi-Fi solutions
• Mobile operators are squeezed by Wi-Fi / Wi-Max,
  but also develop UMA
• New players (MVNOs, CLECs, Google, Skype),
  squeeze everyone
• Core revenue (voice) is saturated and profit
  declining
• Whilst voice revenue stagnates, Data revenue
  increases
• Network costs are too high, and old equipment
  need replacing
• Networks are complex, hard to scale and
  interoperate
• Operators are tied to vendors for dedicated
  technologies
• Roll-out time for new services is too long

Evolve or become extinct

• Option 1 Stick head in sand and ignore the storm
• Continue down the same path, upgrade existing TDM
• Option 2 Evolve
• simplify the network (reduce complexity and cost)
• become access independent (mobile / fixed)
• offer new services quickly and on demand
• concentrate on content and services
• Most operators seem to have chosen Option 2
• Orange UK and Wanadoo Test IMS solutions
• BT announce National network migration 2008gt
• France Telecom FMC user trials underway
• KPN (Netherlands) FMC user trials underway
• T.I.M (Italy) IP based Video sharing launched
  2005
• Telefonica (Spain) IMS deployment begins 2006
• and many more

Operators fight back with NGN

• NGN will
• Provide a migration path from PSTN/ISDN to an IP
  based core, whilst maintaining existing services
• Reduce CAPEX and OPEX, give better ROI
• Provide a common foundation for fixed, mobile and
  enterprise services
• Allow the quick creation and deployment of
  innovative new blended services on demand
• Provide flexible dimensioning, easily scaleable
• Allow advanced centralized network control, for
  charging, OM and more
• Attract the third party service providers without
  loosing control of the network
• Open interfaces allow vendor independence, the
  best equipment can be chosen for each layer

11
IMS one Platform for Convergence

• NGN can initially exist without IMS
• MPLS / IP solutions are already being deployed
  (e.g. BT 21CN)
• Mobile SIP-based IMS is at the core of both 3GPP
  (W-CDMA) and 3GPP2 (CDMA-2000) networks
• 3GPP IMS is being re-used for the NGN as defined
  by TISPAN
• Tomorrows entire multimedia world will
  eventually be IMS based
• IMS based network trials are underway
• Roll out of IMS based networks expected in 2008gt

12
What is IMS?

• IP Multimedia Subsystem as defined by 3GPP
• IMS is defined by 3GPP from Release 5 onwards
• IMS standards define a network domain dedicated
  to the control and integration of multimedia
  services.
• IMS builds on IETF protocols
• Based on SIP (for session control), Diameter (for
  AAA) as well as several others (RTP, RTCP, STP)
• 3GPP have enhanced these protocols for mobility
  with the IETF as opposed to fixing them
  in-house
• IMS in short
• Open-systems architecture that supports a range
  of IP-based services over the PS domain,
  employing both wireless and fixed access
  technologies
• IMS key specifications
• 3GPP TS 22.228 IMS stage 1 (service
  requirements)
• 3GPP TS 23.228 IMS stage 2 (architecture)
• 3GPP TS 24.229 IMS stage 3 (protocols)
• 3GPP TS 24.228 IMS signalling flows

13
What does IMS provide?

• Services and Control
• Adds (SIP) call session control to the packet
  network
• Enables real-time services - such as voice, video
  - over a packet-switched domain (p2p, VoIP, IM,
  presence)
• Enables signalling to be separated from transport
  data
• Mixed Multimedia
• Ability to pick and mix various multimedia flows
  in single or multiple sessions
• Does not define services, but provides flexible
  enablers
• Connectivity Access Network Independence
• Provides access to IP based services independent
  of the connectivity network mobile (3GPPs UMTS,
  3GPP2s CDMA2000) and fixed networks (TISPAN)
• Simple Internet plus
• Enhanced security, service based QoS, single
  sign-on and flexible charging

17
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.

Proposal to stop IMS fragmentation

• The scope of 3GPP will be extended to include the
  requirements coming from other communities.
• Mechanisms will be put in place to ensure
  efficient requirements capture from different
  industries.
• 3GPP will be responsible for producing one set of
  IMS specifications that satisfies the various
  requirements.
• Expected these new arrangements will be put in
  place during 2007.

TISPAN NGN-R1

• NGN Rel-1 was completed at TISPAN9 (Dec. 2005)
• Provided the first set of implementable NGN
  specifications that are now being used by
  industry to build the NGN.
• Main objectives - PSTN Replacement Multimedia
• Provides the overall architecture for NGN
• Defines the various subsystems and how they
  interwork
• 3GPP Rel-7 IMS re-use and its relationship to
  other TISPAN NGN components
• Defines PSTN/ISDN Emulation Subsystem (PES)
• Defines PSTN/ISDN Simulation Services (PSS)

TISPAN and 3GPP synchronisation

• TISPAN R1 timescales and dependencies were
  aligned with 3GPP Release 7 work on FBI.
• TISPAN NGN Rel-1 definition completed Dec 2005
• TISPAN NGN Rel-1 corrections up until May 2007
• 3GPP Rel-7 completion planned March 2007

• 3GPP will freeze Rel-8 requirements by end 2007

25
Rel-2 main features

• TISPAN is progressing the work on Rel-2
  concerning the following main new work items
• Requirements analysis for FMC (with such bodies
  as FMCA).
• Requirements analysis for home networking (in
  cooperation with such bodies as HGI).  
• Requirements for network capabilities to support
  IPTV services (in cooperation with e.g. ATIS IIF
  and DVB).
• IPTV Integration of NGN Services and Capabilities
  using IMS
• Support of Business Services and Enterprise
  Network inter-working.
• Close co-operation for corporate with Ecma Int.
  on
• NGN Business services and Enterprise
  capabilities.
• NGCN NGCorporateN interconnect requirements.

26
Main points to take home

• Telecoms network convergence is inevitable
• IMS is a pivotal point for the ensured success of
  NGN
• A single place for IMS specification is essential
  to avoid IMS fracture, and that place is 3GPP
• Robust and open global standards are key to the
  long term success of the NGN

• This is NOT the end
