o What are we looking for?• Telcos’s expectation on NGN and IMS.
o Opinions on the Deployment• Possible relationship between SX and IMS• Some Examples for the real deployment

What Telcos are doing without IMS?
o Circuit-based• Perfect Voice Communication• Basic Data Communication, partly convergence• Basic Multimedia Communication, partly
convergence
o IP-based• Perfect Inheriting of Voice Communication• Broadband Data Communication, but most
independent deployment• Multimedia Communication, more convergence
than Circuit Age

What Telcos wish IMS could do?
o Layered architecture • Separates transport, control and applications• “We can buy best of breed at every layer!”
o Access-agnostic• Simpler convergence of fixed and mobile networks• “Services no longer tied to access network technology!”
o Real-time IP applications • With QoS, security, charging• “A means to fight IP applications leakage to the Internet!”
o New kinds of applications• Blended together • “Higher ARPU, lower churn!”
o More applications, much more quickly, at much lower cost• But controlled, supplied and billed by service provider • “No need to rely on a few killer apps!”

What’s IMS services?
o Messaging services (IM, SMS, MMS etc.) o Push to talk over NGN (PoN)o Point-to-point interactive multimedia services (e.g. interactive real-time voice,
real-time text, real-time video, total conversation, voice telephony with text, etc.)o Collaborative interactive communication services (multimedia conferencing with
file sharing and application sharing, e-learning, gaming)o Push-based services (e.g., IP multimedia services, MMS, and new services including
public safety, government, corporate IT etc.)o Content delivery services (Radio and Video streaming, Music/Video on demand, TV
channel distribution, financial info distribution, professional and medical image distribution, electronic publishing)
o Broadcast/Multicast serviceso Hosted and transit services for enterprises (IP Centrex, etc.) o Information services (e.g. cinema ticket info, traffic status, advanced push)o Location based services (tour guide, assistance for emergency call etc.)o Presence and general notification serviceso Real-time conversational voice serviceso 3GPP Release 6 and 3GPP2 Release A OSA-based services
IMS will start from non real-time, non voice service first: data-based service

Conclusions
o We are looking for……• Money and Flexibility !!!
— Revenue from new APP— Open Arc to reduce COPEX— Be Converging and easy to deploy new APP to
reduce OPEX— ……
o But we must think about ……• What’s the real situation of the APPs to
market?• Evolution not Revolution to future

SoftSwitch vs IMS in General
o IMS is a clear trend, especially for the non real-time services;
o There is no confliction between the softswitch and IMS.
o Softswitch is the best way if the requirements focus on the voice communication.
