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 …
