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.

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

13

IP Multimedia Subsystem Open-systems architecture that supports a range of IP-

based services over the PS domain, employing both wireless and fixed access technologies

IMS 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

What is IMS?

14

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)

What does IMS provide?

What is being done?

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 networkbased 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 creatinga set of implementable NGN Rel-1 Specifications

ITU-T has set the Framework for NGN

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

NGN Requirements

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 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

Conclusions

30

IMS is stable and clearly specified by 3GPP in Rel-6IMS 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 optionBetter to have planned convergence than unplanned collisionIf you want to influence the standardization process, the time is to do it is …
