Adoption of 3G/UMTS IMS in NGN
 IP Multimedia Subsystem generally establish
NGN requirements for conversational services
With Release 6 becomes applicable to a range of
access network types
Access independence
 Whole Telecom industry benefits
Market stimulation, decreasing costs (thanks to shared
development & deployment costs)
One Development path, one NGN

_NGN Release 1 scope
 Consolidated by mid-2004
 Major service capabilities under consideration include
 Real time conversational services (Voice, Video telephony)
 Messaging (Instant Messaging, MMS), Presence management
 Content delivery (VOD, Video Streaming, TV-Channel
distribution)
 Emulation for PSTN/ISDN migration towards NGN
 Network Architecture basis
 3G/UMTS IMS sub-system for the support of real-time
Conversational services (SIP-based session control)
 ADSL access
 WLAN (later decision)
 Design Approach
 Pragmatic bottom-up approach for Release 1
 Top-down (TIPHON-like) approach to ensure NGN goals

_NGN high level Roadmap
Towards a converged Wire line and Cellular NGN …
Release 1 Release 2
xDSL,
WLAN
FTTx
Release 3
Fully
Nomadic
???
2004 2005 2006 2006 2007 2008
 Release 1 bringing video & Multimedia services
 Nomadicity/user-controlled roaming
 Based on use of Access network Attachment Subsystem
 Release 2 optimizing (dynamically allocated) resources usage
 According to user subscription profile and service use
 Release 3 introducing full Mobility
 Inter-network domain nomadicity/user-controlled roaming
 Higher bandwidth access(VDSL, Wi-max …)

Leverage Global Standards for NGN
 There are a number of areas where commonality between 3G
IMS adapted to fixed NGN:




SIP-based Call/session control
Call server-Service/Application control interfaces (ISC, Dh, Sh)
AAA (e.g. Diameter at Rf interface)
Management
 Possible approaches are:
 Define xDSL access Delta compared to relevant stable 3GPP specs
 Re-use and adapt IMS R6 specs for full TISPAN_NGN spec
 Contribute Deltas to 3GPP IMS future work
 Course of actions:
 TISPAN_NGN to progress on its Release 1 work
 Discuss and define the xDSL requirements and differences compared to
3G IMS, taking 3GPP IMS Release 6 as the base reference
 Plan a joint Workshop with 3GPP SA and CN (on 22-23 June)
 Define a stable TISPAN_NGN R1 reference architecture (by Sept. 04)

_NGN Summary
 A strong industry demand
 For new generation Multimedia services
 For the provision a PSTN/ISDN Emulation service
 First Release of specifications by mid-2005
 Based on existing global standards
 An architecture basis consisting of a set of subsystems
 Maximising Wire line and Cellular convergence, through adoption
of 3G/UMTS IMS component for support of conversational services
 Access network attachment, Resource and admission control subsystems … preparing for next Releases capabilities support
 TISPAN to collaborate with 3GPP
 Workshop being scheduled on 22-23 June
 To identify areas of synergy and plan future collaboration
