Structure • Telecoms trends - the push to converge • IMS - the platform for convergence • Next generation standards • ETSI TISPAN, making NGN standards • Conclusions

Fixed Mobile Broadband Changing Telecoms Trends • Fixed line usage is reducing dramatically for “classical” services • Mobile use is increasing steadily even though penetration is already high. • Broadband Internet deployment shows a rapid growth trend.

OPERATORS WANT MORE CUSTOMERS NEW SERVICES REDUCED COST INCREASED REVENUE HARMONIZED NETWORKS FAST TO MARKET

VENDORS WANT MORE CUSTOMERS NEW PRODUCTS REDUCED COST INCREASED REVENUE HARMONIZED EQUIPMENT BRAND RECOGNITION

CUSTOMERS WANT New Services PERSONALIZATION MOBILITY VALUE FOR MONEY SIMPLICITY FREEDOM

These Trends are pushing for… • Fixed – Mobile Convergence (FMC) • the integration of mobile and fixed technologies to enable the seamless distribution of services over fixed and mobile broadband networks

IMS the Platform for Convergence • IMS is at the heart of Next Generation Convergent Networks • Mobile SIP-based IMS (IP based Multimedia Subsystem) is the core of both 3GPP (GSM evolved) and 3GPP2 (CDMA evolved) networks … this is not simply a European view • Tomorrow’s entire multimedia mobile world will be “IMS” based • SIP (Session Initiation Protocol) based IMS is IP end-to-end • Applications and services can be supported seamlessly across all networks • SIP is also at the heart of the Internet SIP

What is IMS? • IP Multimedia Subsystem is defined by 3GPP • IMS standards define a network domain dedicated to the control and integration of multimedia services. • IMS is defined by 3GPP from Release 5 onwards • IMS builds on IETF protocols • Based upon SIP, SDP, COPs and Diameter protocols • 3GPP have enhanced these IETF protocols for mobility • 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

What does IMS provide? • Services and Control • Adds call session control to the packet network (GPRS) • enables peer-to-peer real-time services - such as voice, video - over a packet-switched domain • Mixed Multimedia • Ability to pick and mix various multimedia flows in single or multiple sessions • Can handle real-time voice, video, data • Connectivity Independence • Provides access to IP based services independent of the connectivity network: mobile (3GPP’s UMTS, 3GPP2’s CDMA2000) and fixed networks (TISPAN’s NGN)

Making Standards THE STANDARDS ARENA IS HIGHLY POPULATED

What is being done? • ITU-T FGNGN has set the Framework for NGN • 3GPP members are working in the IETF to ensure that the underlying protocols fit with 3GPP (mobile service) requirements • 3GPP has developed IMS, it is now stable, and is being enhanced • OMA is defining services based on the 3GPP IMS service platform • ETSI TISPAN is busy defining the NGN networkbased on 3GPP IMS • 3GPP and ETSI TISPAN are meeting jointly to adapt 3GPP IMS to fixed access networks • ETSI TISPAN is feeding back to the ITU-T and creatinga set of implementable NGN Rel-1 Specifications

ETSI - TISPAN • What is ETSI? • ETSI is an independent, not for profit organization, whose mission is to produce telecommunications and ICT standards for the global market place. • What is ETSI TC TISPAN? • TISPAN in an ETSI technical committee, dealing with fixed networks and migration from circuit switched networks to packet-based networks • TISPAN focuses on all aspects of standardization for present and future converged networks including NGN • TISPAN produces detailed implementable deliverables that cover NGN services, architectures, protocols, QoS, security and mobility aspects within fixed networks

TISPAN_NGN Genesis • A strong industry demand • For new generation Multimedia services over xDSL access • For preparing replacement of soon becoming obsolescent PSTN • For a first Release of specifications in 2005 • Giving main standards directions • With realistic and implementable solutions • ETSI TISPAN has developed an architecture consisting of a number of subsystems: • Access network attachment Subsystem, Resource and admission control sub-system • Maximizing Fixed and Mobile convergence, through adoption of 3G/UMTS IMS component for support of conversational services • TISPAN collaborating with 3GPP to accommodate Wireline access network requirements by IMS • A workshop held with 3GPP in Washington end of March 05 • To coordinate the IMS evolution and resolve issues • TISPAN contributing to ITU-T on a global standards • ITU-T CSI, SG4, SG 11, SG 13, SG 19, as well as other SDOs

NGN Services Requirements • TISPAN_NGN supports legacy POTS services (PSTN/ISDN Emulation) • Emulates the PSTN/ISDN Telephony service over an IP infrastructure • This will enable use of the existing ISDN Supplementary services • TISPAN_NGN R1 defines Voice Service (Simulation) • Similar - but not identical - to existing PSTN service • Including important supplementary services • Based on IMS capabilities for basic voice call • TISPAN extensions for simulation will to be included in Rel-7 of 3GPP IMS • Standard capabilities with the aim of making the services applicable for other IMS networks than TISPAN IMS, e.g. mobile networks to facilitate seamless fixed mobile convergence for Telephony over IP services

Joint working: 3GPP & TISPAN • TISPAN has incorporated the 3GPP IMSinto it’s NGN Architecture; i.e. a common IMS • 3GPP and TISPAN are developing a single IMSthat incorporates mobile and fixed requirements • 3GPP and ETSI TISPAN are meeting jointlyat both Plenary and WG level • TISPAN and 3GPP have a single Project Managerand harmonized Work Plans / Roadmaps,i.e. common work planning

Key points to take home • IMS is stable and clearly specified by 3GPP in Rel-6 • IMS is the platform of choice for Mobile to Fixed convergence • Standardisation involves close coordination between different bodies such as IETF, 3GPP, TISPAN, OMA, ITU-T, etc. • Robust and open global standards are essential to the long term success of IMS and NGN • Doing Nothing is NOT a sensible option • Better to have planned convergence than unplanned collision • If you want to influence the standardization process, the time is to do it is … NOW
