4. Features marketed as ‘next-generation’ are
underwhelming
Improved battery life
Faster call set-up times
Main benefits claimed in marketing for VoLTE services
High-definition voice
Simultaneous voice and data
Rectifies a shortcoming
Potential for competitive differentiation
Limited marketing potential
Difficult to ascribe value to operator
Limited penetration – needs interconnect
Variable quality (better than OTT, not necessarily 3G)
Issues only when outside acceptable limits
Learned protocol, not customer choice
Limited marketing potential
Questionable results to-date
Dependent on high or contiguous coverage
Limited marketing potential

6. Status of global VoLTE implementations
Ali.Saghaeian [at] gmail.com
7. Some of VoLTE Launch Challenges
VoLTE client & chipset integration
Addressing limitations in technology
Coverage gaps between legacy & LTE
Vendor product gaps – feature requests
Customer Experience
Single number routing is a major issue
Standards do not define how service synchronization between CS and IMS works
Avoids duplicated charging on users IN, SRVCC calls
Biggest challenge with ensuring user experience!!
Seamless vs. new and improved
Service Parity
Option 1: Re-invest capital to re-do features on new platform
Option 2: Start fresh with new capabilities
Options 3: Only keep the popular services, not all CS services

8. Beyond VoLTE: Customer Centric Service
Innovations
Revive Lost Business Sources
Create New Revenue Streams
Address Daily Needs of Modern Connected Lives
Enable Distinct Persona & Context for Conversations
Solve Very Specific Communication Challenges Innovate Like OTTs to Establish Operators as Primary CSP

3 200 to 220 VoLTE-capable devices available 72% of smartphone consumers are interested in using an HD voice service 60% would use an app from their CSP to make and receive voice calls if it does not consume mobile data Source: Alcatel-Lucent 2015 survey of 5,504 smartphone end users in USA, UK, Japan and Brazil
International VoLTE market drivers for MNOs
• New roaming opportunities for CDMA MNOs
• Expands rich voice service to international calls
• Simplifies international interconnect for VoLTE calls
Ovum survey and whitepaper (Feb 2015)
• 50% of MNOs to deploy international VoLTE within 6 to 12 months of
domestic

10. VoLTE vs OTT Voice Call
• VoLTE improves service quality of existing voice calls and differs from OTT
voice calls by its guaranteed QoS (quality of service)
・Basic services provided by carriers that must follow telecom regulations
・Various players offer voice call services based on internet technology (VoIP)
・No regulation and quality is NOT guaranteed
OTT Voice Call
Voice Call by Carrier(VoLTE) <VoIP Apps>
Low Cost with Wi-Fi or Cellular Unlimited Data Plan
No Quality Guarantee

13. VoWiFi Business Drivers
• New Services - Compete against the main OTT VoIP and video
competitor (Skype) – enhanced user experience / loyalty /
Incremental revenue
• Offer Indonesian or anyone outside Indonesia a service to call back
to Indonesia without incurring Roaming Charge
Offer Indonesian subscribers a service to receive calls on the
mobile number without incurring Roaming Charge
Coverage & Network Offload - Better user experience and
macro network offload (70% of mobile usage is inside
office/home) – lower churn and cost
• Easy Billing - A challenge in many Asian countries with low use
of online payments and credit cards - faster revenue realization
• Brand Dilution - Avoid being perceived as a “dumb pipe”
provider - attach users to innovative services and keep the
brand fresh
• Network Transformation - Prepare the organization to more
easily evolve to IMS based HSPA+, VoLTE and RCS services – 4G
network readiness

14. Consumer Use Cases for VoWiFi
‘Roaming CS Avoidance’
Improved Service Coverage
‘Roam Like Home’
Roaming for Non-Subscribers When roaming, use WiFi for calls
WiFi App detects handset is roaming
Calls are always placed using WiFi
Usage is ‘home rated’ based on home plan Consumer benefits from local rates. Home operator benefits because it gains revenues from calls which otherwise would have been made on a competitors service or not made at all and avoidance of bill shock.
Use roaming 3G/4G data plan for VoIP calls
Roaming Data may be lower cost than Roaming Data
Total data consumption of a VoIP call is low
Its lower cost to make a VoIP call over 3G than CS
When roaming app uses 3G/4G data network as VoIP call. Consumers benefit by avoiding costly Circuit Switched calls
Switch to WiFi in poor 2G/3G coverage
Users are surrounded by multiple network bearers
WiFi App selects WiFi bearer when its available and best choice.
Usage is still ‘rated’ based on users plan. Consumer benefits from extended coverage and quality. Operator benefits from revenues from calls which otherwise would have not been made and avoidance of bill shock.
Visiting users buy package of local ‘voip’ minutes
Users download ‘app’ when arriving in new network
Calls are routed as VoWiFi or VoIPo3G/4G
Rated using a local pre-paid plan rather than roaming Consumer benefits from local rates. Roaming operator benefits from increasing local termination revenues which might have otherwise been avoided. Home Operator benefits from lack of bill shock.,

15. What Operators are Saying about VoLTE and
VoWiFi
Clear conversations and
reduced background
noise so you feel like
you’re right next to each
other. Make and receive
high-definition voice
calls and enjoy:
• Crisp call quality
• Less background noise
• Simultaneous voice
and data at 4G LTE
speeds
May 23, 2014
VoLTE is the next
major advancement in
LTE; customer benefits
include faster call
setup times (almost
twice as fast) and HD
Voice.
Launching VoLTE is
our first step toward a
host of rich
communication
services and additional
innovations around Wi-
Fi calling.
May 22, 2014
We believe the
combination of this
robust network along
with the new features
is going to create a
new, meaningful
experience for our
customers for their
calling needs.
HD Voice and video
calling would be the
two main services
initially offered through
VoLTE technology.
May 20, 2014
EE has announced
plans to launch VoLTE,
with a VoWiFi service…
both promise
improvements in
quality-of-service over
traditional circuitswitched
calls.
Both services are
enabled via an IMS
capability in EE’s
network.

and VoIP
Note: VoLTE and VoIP are mobile-specific; VoWiFi could be from any Wi-Fi connection. Circuit-switched
mobile voice is excluded from the mix.

23. Operator’s Opportunities via webRTC
OTTs:
• Threatened by this disruptive
technology
• Defensive approach - Extending
their endpoint to Web
• Consolidation in the OTT segment
or collaboration with Telcos
Operators:
• Extend reachability of existing Telco
services
• Offer multi-media rich services on
multiple devices over multiple
access networks
• Create new services for vertical
markets in the home context
Mobile Operators can offer ‘Google Voice’,
‘Google Hangout’ like services with 1 number,
multi-device access – smartwatch, smartphone,
Tablet, Laptop, TV over multi access network
