4. 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.
Broadband

Fixed
FIXED: operators face NEW challenges from low-cost operators, mobile operators and VoIP. Although profits on fixed voice and data are presently high, the trend is for steeply decreasing volume due to new competitive technologies as well as pressure on prices and margins.
Fixed has the advantage of quality and reliability and will look to reducing network costs and increasing revenue through new services. MOBILE: End of 2005, there will be almost two billion mobile subscriptions worldwide. Strong growth in developing countries (including Asia and Latin America)
Voice is still the main source of revenues and profits (80%)
New profit opportunities from enhanced content such as ring tones, wallpapers and games, and new services (Conferencing, Streaming, Chat).
Mobile operators are opening new (world) markets, eating the fixed operator minutes, as well as developing new services.
BROADBAND: continues to proliferate - technology delivering ever increasing bandwidth to a demanding customer base. However profits tend to decline due to competitively between providers. Churn is high and overall profit is low
VoIP: call volume and the user base is rapidly increasing, rapid take up in businesses for corporate communications. However growth is limited by shortfalls in VoIP's quality and reliability.

12. 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

13. 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

14. What does IMS provide? Services and Control Mixed Multimedia
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)

17. 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

20. 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

22. 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

23. 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

24. TISPAN NGN Architecture

Conclusions

32. NOW 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 …
