What is IMS ?




IP Multimedia Subsystem
Unified Network Architecture for service offering
A functional model structured in levels
Service oriented NGN

Current Status of Network

Old-fashionned access network
(“no” packet mode transport)

Obsolete TDM Switching

NGN deployed partially

Value Added Service Platform running over circuit switch model and
integrated at Telecom Operator’s Operational Process

Where do Investments?

Maximize investiments on applications:




Minimize investments on Infrastructure:


new services offering
differentiate offering over market competition
new revenue sources
Maximize usage of TDM network
Focus investments on new technologies

minimize investments on legacy network
20
Technical View

3GPP and 3GPP2: focus on 3G network evolution

TDM network are connected to IMS environment throughout Trunking
Media Gateways.

NGN-By-The-Book and Main Issues - #1
Value Added
Services
• Issue #1:
VAS
~ 30%
 High CAPEX: IP backbone & gateways;
 Multi-vendor environment: NOT Real;
 Real Deployments: only when RoI is
guaranteed

resource is required from IP Network

How do Invesment ?

Investment on IMS Core


Investment on Application Servers


Common infrastructure that allow new services offering for any network
access
New revenue based on new services.
Minimize investment on control and transport Infrastructure


Trunk Media Gateway is transition equipment
No further function for Trunk Gateway on 3G Networks
Investment on Trunking Media Gateways is
NOT investment
on NGN!
It is investment on LEGACY NETWORK!

CONCLUSION



IMS Migration Advantage: centralized VAS platform
VAS delivered for any access network
Investment focused on new Value Added Services
Standard Interfaces - Open protocols (Multi-vendor
environment)
Gatewayless proposal:

Platform for call and service control:
- Legacy network (TDM)
- NGN network
… or ANY combination of these networks
Unifying legacy and NGN Service Platform


Legacy network (TDM) connected with IMS in a optimized resource
allocation
Evolve to IMS
