1. 1 Global Standards, the Key Enabler for the Next Generation Network 

2. 2 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/

4. 4 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 ???

5. 5 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

6. 6 Customer expectations are evolving

7. 7 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

11. 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 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. 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

13. 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

17. 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.

18. 18 3GPP capture requirements

19. 19 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.

21. 21 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)

22. 22 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

23. 23 TISPAN architecture is based on a concept in which various subsystems, among them the IMS and the PES, will communicate through standardized interfaces, with functional elements common to all subsystems. The main elements of the TISPAN architecture are the RACS and the NASS. The main functions of the NASS are: Dynamic provision of IP address and other user equipment configuration parameters (e.g. using DHCP); User authentication, prior or during the IP address allocation procedure; Authorization of network access based on user network profile; Access network configuration, based on user profile; Location management (e.g. for emergency call, …); CPE configuration; NASS provides support for nomadicity and roaming and can be distributed between a visited and home network. With respect to RACS, it is responsible for: Service Based Local Policy Control: It means, authorization of QoS requests and definition of the polices to be enforced by the bearer service network elements. Support for Application Function (AF) including QoS support over multiple access networks (for instance ADSL and GPRS) and CPE types. Apply admission control to resource reservation requests according to network policies. This is applied based on knowledge of transport resource availability over the “last-mile access” and aggregation segments of the access network NAPT/ Gate Control: controls near-end and far-end NAPT and FW functions, when required, between two core TISPAN NGN networks or, at the border between core and access TISPAN NGN networks. Last December, it was concluded TISPAN release 1. The major issues of this release are presented in the next slide.TISPAN architecture is based on a concept in which various subsystems, among them the IMS and the PES, will communicate through standardized interfaces, with functional elements common to all subsystems.
