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…)

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!

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

All

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

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 and VoLTE Subscriber forecast

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…

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


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

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


Topics







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


Real-time IP Media Processing The Foundation for many Communication Services

Question?

What do all these

communication services

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.


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
