Telephony
Replacement
RCS = Modern Communications
Foundation is IMS - “raise the bar”
RCS
… must view RCS as not a replacement for
telephony but as modern communications..
OTT
Fully interoperable & reliable likefor-like rich services competitive
with Skype, WhatsApp, etc…
The very nature of communication is shifting
Give consumers what they expect, or they go
elsewhere
Multi-device… mobile/tablet/PC experience
integrating messaging, media, video, voice
Open question: Will social media
platforms leverage RCS or continue to
provide their own communications
services?
Richer User Experience

But can operators move quickly enough?

What do OTTs bring to the Industry?
Disruption
Voice and Messaging revenues
Varied experience… test the threshold of “acceptability”/tradeoffs
Driving the cutting edge of user experience
Multi-device communications experience
Proving demand for rich media communications
Educating consumers in a cost-free, risk-free environment

Operator Opportunity – Enterprise Services
 Enterprise communications transitioned a decade ago to modern
communications ->
 RCS is the same paradigm as modern enterprise communications that support
presence, messaging, file exchange, voice, video, and multi-device and mobile
communications.
 RCS offers the mobile operator an opportunity to host these communications or
to interwork with enterprise versions of the same as well as hybrid models
where the operator may provide some services in the network by being in the
path of communications
 RCS hosted or interworked plays to operator strengths and new realities…



Security: Cloud based messaging firewalls/anomaly detection SPAM mitigation, denial
of service prevention, leverage strong SIM authentication, …. Too many to list
Compliance: Record & keep metadata from messaging, file xfer,
conversations…enterprise audits & external regs (HIPAA/SarBox)
Cost containment: Accounting & one stop billing, spending limits
Identity & Contact Control : Enterprise identities preserved, enterprise remains in
control of its identities, enterprise can manage employee address books & contact lists

Operators Need to look at RCS as “Table Stakes”?
RCS enables operators to provide competitive like-for-like services as OTT but
better…
OTT competition
RCS-e is about competing with Whatsapp, etc.
RCS v1-4 was about competing with Skype, etc.
RCS 5.x gives operators a launch
pad to tackle OTT threat head-on
Quality of Experience
Device capabilities discovery is viewed as an
essential way to guarantee QoE
Mobile Service Providers
OTT Providers
Essential to avoid 3G pitfalls, i.e. video calling
All OTT services but with
• Single Number
• Single Integrated App
• Quality of Service (QoS)
• Carrier Grade Reliability
• HD Voice & Video
• Global interoperability
• Federation with OTT
IM/Chat Community
Web Messaging /
Message Storage
Mobile VoIP & Video
Multi Device Delivery
VoLTE synergies
Common IMS core, interoperability
Business case for new services becomes more
attractive with IMS justified by VoLTE
And more…

Case Study – Received Call from Landline
Subscriber-B
Subscriber-A
Landline
Call Sub B MSISDN
Skype/Viber
Mavenir RCS
(Received )
RCS vs. OTT
Mavenir RCS
Sub B can receive the call
via RCS
Skype or Viber
Sub B CANNOT receive the call because
Sub A is not calling from Skype/Viber
Benefit of RCS VoWifi/VoData
To Subscriber
To Operator
Sub B on RCS can be
reached by Sub A using both
landline & mobile
Operator will see increase in subscriber
take up as subscriber will sign up to this
service
12
Case Study – Emergency Call/Message (911)
Subscriber-A
RCS/OTT
Call 911
Message 911
RCS vs. OTT
Mavenir RCS
Sub A calls for help or sends
emergency message
Skype or Viber
Skype doesn‟t support emergency calls.
No messaging support to PSAPs.
Benefit of RCS
To Subscriber
To Operator
Sub A reaches emergency service.
Mobile location available even if sub
doesn‟t know where they are (device
dependency)
Superior service enabling services to
everyone and landline replacement.
Regulatory advantage.

Case Study – Take Call from RCS/OTT
Subscriber-B
Subscriber-A
RCS VoWifi
Take Call
Skype-Out
Call Sub B MSISDN
RCS vs. OTT
Mavenir RCS
Skype or Viber
Sub B will see Sub A
MSISDN and takes the call
Sub B CANNOT see Sub A MSISDN as
calling party info is not available. Sub B
might not answer unidentified calls...
Benefit of RCS VoWifi/VoData
To Subscriber
To Operator
Sub B will see Sub A
MSISDN and takes the call
Operator can keep all the revenue from
calling party Sub A
14
Case Study – Missed Call Notification
Subscriber-B
Subscriber-A
RCS VoWifi
Missed Call
Skype-Out
Call Sub B MSISDN
RCS vs. OTT
Mavenir RCS
Skype or Viber
Sub B can get a miss call
alert from operator when
back in coverage
No missed call alert from operator when
sub B moves back in overage
Benefit of RCS VoWifi/VoData
To Subscriber
To Operator
Sub B on RCS can get
missed call notification with
caller ID and return call
Revenues when Sub B returns call

RCS vs. OTT
Mavenir RCS
Skype or Viber
Sub B can receive the call via
VoWifi/VoData, Sub A CAN hear
customized RBT of sub B
Sub B can receive the call via skype or
viber client, but Sub A CANNOT hear
custom RBT of sub B
Benefit of RCS VoWifi/VoData
To Subscriber
To Operator
Subscriber can enjoy services
such as custom RBT
Operator can continue to sell
supplementary services for RCS
VoWifi/VoData

LTE or managed WiFi without any skype or viber client, but the video
QoS issues
quality cannot be guaranteed
Benefit of RCS VoWifi/VoData
To Subscriber
To Operator
Guaranteed services
Operator can sell different classes of
services (Gold/Silver/Bronze)
