What’s Life Like ….

• Today• Most people can’t do without their mobile phones

• Content is on DVDs or magazines or books or a local hard-disk

• Contact List by application, device, and individual situation

• In 2010 ….• Everyone is connected and people can’t do without being on-line

• The first place people go for content is on-line

• Informal peer groups and sharing is open and legal

• In 2015 …..• Everyone and everything is connected all the time, everywhere

• The only place people go for content is on-line

• Dynamic communities of interest without any boundaries

Today’s technology savvy teenager (software downloading, IM addicted, camera phone wielding) is grown up, a key decision maker at home and at work, and your target customer!

What is NGN ?

• Full (carrier class & business class) service network• Telephony and other Legacy (including Internet access) services• Data, including high speed access to Internet and its applications• Video (VOD, Streaming)• Digital TV Broadcast, Multimedia (combining all of the above)• Mobility and Nomadism. Interworking with Legacy services• For Human and Machine users (including RFIDs machines)

• Network features and technical characteristics• Packet-based (IP, MPLS, ATM, Ethernet) transport• IP and service intelligence, in an IP-managed network• Distributed, transport-resource-session-service independent control• Using IP-friendly (well defined profile) protocols

When is NGN coming?

• Some (pre-NGN) pieces are already here:• PSTN (VoIP, VoATM) trunking, some VoIP offers• Private/corporate network solutions (Centrex IP, IP VPN…)

• Convergence of Telephony and Data (IT, Internet):• PSTN/ISDN evolving towards NGN oriented platforms

• Replace obsolete PSTN/ISDN network elements: 2005+• Packet Data networks evolution (Fixed-Internet convergence)

• Evolving from the current High Speed Internet access (ADSL, WLAN …) platforms

• To offer new generation Services: 2005 onwards• Mobile convergence (IMS): 2006 onwards

How will NGN be deployed?

• Progressively replace legacy PSTN elements/areas• When obsolete (too little OPEX/CAPEX gain, esp. in Core)• Migration PSTN->NGN may accelerate after 2010 (PSTN lines moved to

DSLAMs -> VoIP)

• Green field deployment (today)• Overlay: build over xDSL, Fiber access to Internet

• Rapid deployment of ADSL, large investments• Opportunity to provide new (audio-data-video) services

• Convergence of Fixed-Mobile and Internet services/applications• Nomadicity (Mobility Management for Roaming)• Mobility through Fixed WLAN• Harmonizing/Converging with Mobile IMS and IP-Cable

ITU-T and NGN

• SG 11• Network Signalling and Control functional architectures,

requirements and protocols in NGN

• SG 13• Functional requirements, services and architectures

• SSG• Vision for IMT-2000; Mobility Management• Convergence of Fixed and Mobile

• SG16• MM Services specifications applicable to NGN: H.323, H.248, etc.

• N.B: all SGs have an “NGN” aspect to their work

ITU-T NGN Project

• Joint ITU-T SG13-SSG session on NGN, 5 Nov 02 • NGN-2004 Project description

• http://www.itu.int/ITU-T/studygroups/com13/ngn2004/index.html

• Definition of NGN • Workshop on "Next Generation Networks: What, When

and How?“• Geneva, 9-10 July 2003

• Joint Rapporteurs Group on NGN (JRG-NGN)• 4 meetings in 10 months• 11 Recommendations under development• 2 mailing lists open to non-ITU-T members

Taller Conjunto Sobre Redes de Próxima Generación: Asunción, Paraguay - 11

Focus Group on NGN (1 of 2)

• Addresses the market needs for NGN standards• Created 7 May 2004 to address urgent need to continue NGN

studies over inter-regnum period through WTSA-2004• Goal: produce global standards for NGN• Mid 2005: fold into parent study group addressing NGN• Continues work on draft JRG-NGN Recommendations

• Inaugural meeting 23-25 June 2004, Geneva• Web site: http://www.itu.int/ITU-T/ngn/ • Mailing list: fgngn@itu.int

• Second meeting: 19-23 July, Geneva• Third meeting: late Sept, North America (details tbd)

Focus Group on NGN (2 of 2)

• 7 Working Groups:• WG 1: Service Requirements• WG 2: Functional Architecture and Mobility• WG 3: QoS• WG 4: Control and Signalling Capability• WG 5: Security• WG 6: Evolution• WG7: Future Packet-based Bearer Network

• 2 essential streams of work• add xDSL access to 3GPP/3GPP2 IP Multimedia Subsystem,

complete in mid-2005• continue work of JRG-NGN in preparation for future releases

NGN Standards• Many organizations working on NGNs, future generation

technologies, etc.• Leverage ITU global perspectives for an overall framework• Leverage near term detailed and well-focussed technical work of

relevant bodies into this consistent global framework• Example: ITU-T addressing forward looking global NGN framework,

3GPPs working IMS, ETSI TISPAN being based on 3GPP IMS Rel. 6, OMA working application areas
