6. But what about VoLTE?
LTE growth is exceptional
• Primary driver is faster data speeds for 3G network offload.
However, VoLTE service launches are lagging
(Korea is one notable exception…)

8. VoLTE Success in Korea
Korea is the early world leader in LTE deployments
• Quick to achieve high LTE subscriber penetration across country
• ASIDE: Radisys small cell technology in Korean LTE deployments
Quickly followed by VoLTE launches in 2012
• SK Telekom, KT, LG Uplus
High LTE penetration facilitated VoLTE deployment success
• Minimized need for CSFB and SRVCC
• Resulted in good VoLTE adoption
• Korean users “hearing” benefit of HD audio quality
• ARPU up!
9. VoLTE Launches
2012:
• SK telecom (~15M LTE, 8M VoLTE Subs)
• LG U+ (~9M LTE)
• KT (~8M LTE)
2013:
• T-Mobile US
2014:
• PCCW Hong Kong
• 3 Hong Kong
• AT&T
• SingTel

10. VoLTE Plans in Japan and China
Japan
• NTT DoCoMo has large LTE deployment today (~21M subs).
– On June 24, 2014 launched their VoLTE service
• KDDI Au 4G LTE service has 15M LTE subscribers
– VoLTE launch planned for later in 2014.
China
• China Mobile deploying LTE services
– China Mobile will launch VoLTE, RCS and updated audio RBT to VoLTE by
end of 2014
• China Unicom and China Telecom
– considering VoLTE in future
11. Poll Question
Are you using VoLTE services today?
A. Yes - Using VoLTE today.
B. No - VoLTE is available in my geographic country or
region, but currently not using VoLTE services.
C. No - VoLTE services not available.

LTE VoLTE
LTE is fastest growing mobile
broadband technology
• Broad support and rollout plans in
all global markets
• Both GSM and CDMA operators
moving to LTE
Primary driver has been fast data
speeds, and 3G data offload
But VoLTE launches are lagging LTE rollout.
Korea has shown the world the benefits of broad LTE
deployment, and increasing ARPU through VoLTE services
Majority of world’s operators have been slow
to deploy VoLTE. Why?....

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 call setup much faster.
• 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…

• 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
16. 16Radisys 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
17. 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

Triggers for Change
LTE leading to converged IP network for mobile industry
VoLTE driving need for IMS
• IMS provides opportunity for Common Media Resource Function (MRF)
Video services
• Existing media processing resources often don’t support video
Cloud deployment
• Increasing requirements for media processing in Cloud
OTT and carrier networks are blending/overlapping
• Internet users getting telecom services (WebRTC)
• Telecom service providers reaching out to Internet users
Increasing requirements for reusable,
efficient media processing infrastructure

have in common?

Real-time IP Media Processing
The Foundation for many Communication Services
Question?
What do all these
communication services
have in common?
Answer:
They all share an
underlying need for
real-time IP-based
voice and video
RTP media processing
One Common MRF, shared amongst all
Real-time Communication Services.
22. 22Radisys Corporation Confidential
Summary – One MRF Strategy
LTE and IMS
• Deploying LTE and IMS requires MRF that delivers common
features and services across access networks and applications.
As you deploy additional real-time communication
services…
• Business objective is efficient and scalable reuse of
media resources
• VoLTE, WebRTC, Transcoding, Conferencing, plus many more…
– all can and should use same Common MRF
The more services that share the MRF,
the bigger the benefits
