IMS the Platform for Convergence

IMS is at the heart of Next Generation Convergent Networks

Mobile SIP-based IMS (IP based Multimedia Subsystem) isthe core of both 3GPP (GSM evolved) and 3GPP2 (CDMAevolved) networks this is not simply a European view

Tomorrows 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 acrossall networks

SIP is also at the heart of the Internet

SIP


13/34 13

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 protocolsBased upon SIP, SDP, COPs and Diameter protocols 3GPP have enhanced these IETF protocols for mobility

IMS in shortOpen-systems architecture that supports a range of IP-

based services over the PS domain, employing both

wireless and fixed access technologies

What is IMS?


14/34 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 (3GPPs UMTS, 3GPP2s

CDMA2000) and fixed networks (TISPANs 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 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

ITU-T FGNGN has set the Framework for NGN

ETSI - TISPAN

What is ETSI?

ETSI is an independent, not for profitorganization, whose mission is to producetelecommunications and ICT standards for theglobal market place.

What is ETSI TC TISPAN?

TISPAN in an ETSI technical committee, dealingwith fixed networks and migration from circuitswitched networks to packet-based networks

TISPAN focuses on all aspects ofstandardization for present and future converged

networks including NGN TISPAN produces detailed implementable

deliverables that cover NGN services,architectures, protocols, QoS, security andmobility aspects within fixed networks

Maximizing Fixed and Mobile convergence, through adoption of3G/UMTS IMS component for support of conversational services

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 Supplementaryservices

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 inRel-7 of 3GPP IMS

Standard capabilities with the aim of making the servicesapplicable for other IMS networks than TISPAN IMS, e.g. mobilenetworks to facilitate seamless fixed mobile convergence forTelephony over IP services

30

TISPAN has incorporated the 3GPP IMSinto its 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 jointlyat both Plenary and WG level

TISPAN and 3GPP have a single Project Managerand harmonized Work Plans / Roadmaps,i.e. common work planning

Joint working: 3GPP & TISPAN

Conclusions


32/34

32

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 option

Better to have planned convergence than unplanned collision

If you want to influence the standardization process, the time isto do it is

Key points to take home
