2. Topics
 Industry Hesitancy around VoLTE…. Why?
 Motivations for deploying VoLTE
 Considerations for the Media Resource
Function MRF in a VoLTE Deployment

Industry Hesitancy to deploy IMS for VoLTE
Why?
Perceptions against
VoLTE investments
Reality
Voice is a flat/declining revenue
stream
• Still the largest contributor to
mobile operator revenues and
profitability
Use CSFB for
voice services on LTE
3G networks work fine for voice
• Data falls back to 3G speeds as
well.
• VoLTE sounds better.
• Early VoLTE deployments prove
operators can charge premium and
increase ARPU.
VoLTE handsets not ready,
limited selection, poor battery life
• 2H14 will see increasing variety of
VoLTE devices with improved
battery life
IMS systems, and associated
integration, is costly and complex
• Myopic focus on IMS investment
only, limits understanding of
broader business case benefits…

IMS = IP Multimedia Subsystem
TAS = Telecom Application Server
MRF = Media Resource Function
• Two separate voice and data
networks to manage
• Voice Services supported on
separate, proprietary service
platforms
• One converged EPC for all IP
services simplifies
management
• Open IMS supports VoLTE,
with other interactive
multimedia services
• OneMRF for all services
VoLTE strategy facilitates migration to
converged EPC, achieving OPEX savings

VoLTE forcasted to grow

6. 6Radisys Corporation Confidential
Is an IMS expensive?
Compared to 4G spectrum – No!
Motivation for the CFO:
A VoLTE deployment can
reduce or defer new 4G spectrum purchases,
easily justifying an IMS investment for VoLTE

7. Summary:
Motivations to Deploy VoLTE
 Voice still the “Killer App”
 Single IP network
 Spectrum Refarming
 Revenue Upside beyond
VoLTE services
 Better call quality
 Lower call setup times

So at this point,
hopefully you might be thinking…
“Investing in an IMS to deploy VoLTE
is starting to make more business sense.”
Considerations for
IP Media Processing (MRF)
in an IMS deployment
