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

Operators feel the squeezeMarket competition is increasing

Incumbents squeeze incumbents (internationally)Mobile operators squeeze fixed operatorsFixed operators fight back with Wi-Fi solutionsMobile operators are squeezed by Wi-Fi / Wi-Max, but also develop UMANew 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

Also customers are pushing for more innovative services

Evolve or become extinct

Option 1: Stick head in sand and ignore the stormContinue 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 demandconcentrate on content and services

Most operators seem to have chosen Option 2:Orange UK and Wanadoo: Test IMS solutionsBT announce : National network migration 2008> France Telecom: FMC user trials underwayKPN (Netherlands): FMC user trials underwayT.I.M (Italy): IP based Video sharing launched 2005Telefonica (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, O&M 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

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

Tomorrow’s entire multimedia world will eventually be “IMS” based

IMS based network trials are underway

Roll out of IMS based networks expected in 2008>

12

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

What is IMS?

13

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 (3GPP’s UMTS, 3GPP2’s CDMA2000) and fixed networks (TISPAN)

Simple Internet plus Enhanced security, service based QoS, single sign-on

and flexible charging

What does IMS provide?

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 TISPAN#9 (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)• Network Attachment Subsystem (NASS)• Resource and Admission Control Subsystem (RACS)

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

TISPAN R2 timescales and dependencies are being aligned with 3GPP Release 8 work on FMC.

TISPAN NGN Rel-2 definition complete by end 2006 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

This is NOT the end …

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
