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'. < Bob Dylan 1965 > • 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 • Also customers are pushing for more innovative services

Tomorrow Customer expectations are evolving Yesterday Tomorrow Content and Services Computing Telephone • My contacts • My messages • My calendar • My presence • My applications • My content News Television Interactive gaming Mail Converged Phones IPTVVoD Gaming

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 2008> • 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, 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>

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

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 (3GPP’s UMTS, 3GPP2’s CDMA2000) and fixed networks (TISPAN) • Simple Internet plus • Enhanced security, service based QoS, single sign-on and flexible charging

IMS IMS Technology Convergence IMS has become the point of convergence Fixed Broadband Wireless Access Cable Mobile

IMS Standards Convergence Problem:Related standards are prepared in different places ETSI TISPAN Fixed Access to IMS 3GPP IMS WiMAX Forum CableLabs Cable Access to IMS Broadband Wireless Access to IMS 3GPP 3GPP2 MobileAccess to IMS

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.

3GPP capture requirements ETSI TISPAN 3GPP IMS WiMAX Forum CableLabs 3GPP 3GPP2

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)

Some TISPAN key specifications • Stage 1: • DES/TISPAN-02007-NGN-R1: Overall NGN-R1 architecture • Stage2: • DES/TISPAN-02019-NGN-R1: PES architecture • DES/TISPAN-02020-NGN-R1: NGN RACS • DES/TISPAN-02021-NGN-R1: NGN NASS • DES/TISPAN-02029-NGN-R1: NGN IMS Architecture • Stage 3: • DTS/TISPAN-03043-NGN-R1: 3GPP 29.162 endorsement • DTR/TISPAN-03033-NGN-R1: PSTN/ISDN Emulation • DTS/TISPAN-03044-NGN-R1: PES Stage 3

TISPAN NGN Architecture

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

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.

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 …
