Conclusions
11
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
12
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 IPbased services over the PS domain, employing both
wireless and fixed access technologies
13
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
16
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 network
based 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 creating
a 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
22
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

into it’s NGN Architecture; i.e. a common IMS
3GPP and TISPAN are developing a single IMS
that incorporates mobile and fixed requirements
3GPP and ETSI TISPAN are meeting jointly
at both Plenary and WG level
TISPAN and 3GPP have a single Project Manager
and harmonized Work Plans / Roadmaps,
i.e. common work planning

Conclusions
31
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 …
