Cost & Complexity of Traditional IMS Hinders Service Innovation
Carriers must come to grips with the
fact that IMS is too costly and complex
to adopt in a wholesale manner and
that the architecture will be adopted
over the next few years in an
incremental fashion.

Network Function Virtualization is Cloud for SP Networks
Deploying and delivering
software-based network
functions and services
– Consolidate disparate
equipment types on to
standard high-volume COTS
hardware
– Leverage standard IT

Reasons for NFV
Reduced operating costs
Increased speed of innovation
Resource sharing across services
Finely controlled service introduction
Encourages open ecosystem

Web Cloud is Easier Than Telco Cloud
IT ecosystem is just starting to consider RTC requirements
Media-based functions are the hardest to virtualize
Telco-specific benefits will take time to realize
Purpose-built hardware will continue to play a significant role for the foreseeable future

Elegant design enables virtualization
Requirements Oracle IMS core Typical IMS core
Homogeneous
software Single signaling engine that
integrates 3GPP functions Different software for each 3GPP
function
Minimal interfaces Interfaces dynamically created &
exposed as needed Dozens of static internal and external
interfaces
Simple element
configuration Auto-configuration of new child
elements New configuration for each addition
element
Vital pre-requisite for true elasticity
