Agenda• Introduction

• What are the drivers behind VoLTE and VoWi-Fi roll-outs

• How are these voice technologies deployed

• What are the Diameter signaling implications when deploying VoLTE and VoWi-Fi

• How does the Diameter Signaling Controller enable an MNO to better control 4G voice

• Conclusions

Introduction


The Evolution of Voice and Data• Voice, once the primary revenue service for MNOs, is evolving

• Data is set to become the primary source of revenue

•But, Data is a two-edged sword

• It generates massive new revenue for the mobile network operator

• AND, it creates a fertile battleground in which Over-the-Top players can compete with the MNO and usurp the network operator’s traditional relationship with its subscribers

Voice and Data Contribution ToTotal Revenue

MENA: 53% in 2018Down from 61% in 2013


OTT Voice – the Other Voice• Over the Top Voice is also evolving. Layered on mobile data, OTT

Voice services are supplied by a growing number of Apps

• While these apps have varied success in different markets, their impact is undeniable

The impact of OTT Voice

is Realand Significant


The New Importance of VoiceYour Voice revenue stream is under attack !

• Operators must protect their relationships and revenue stream

• Operators must prevent encroachment by OTT players

• VoLTE and VoWi-Fi are your weapons to fight back 81% of EMEA subscribers

use some form of OTT Voice !

• 2 years ago we talked about whether CSFB was good enough. Its not!

• VoLTE is worth the investment – not just for revenue, but as a defense against OTT – and as a basis for new multi-stream services

VoWi-FiMarket and Drivers


Wi-Fi Nuggets

**16 per cent of mobile users in “key markets” said they had poor or no mobile voice coverage within their home

**89 per cent of respondents with poor or no mobile voice coverage at home were also smartphone owners that had already configured their phone to connect automatically to a home Wi-Fi network.

*Over 50% of smartphone data usage is over Wi-Fi.

Un-trusted Wi-Fi hot spots to grow fast

*People spend 80% of time indoors

So Why deploy VoWi-Fi? - Top Use CasesEnd user benefits• Make and receive calls with your mobile

phone just like at home, no extra charges• Receive calls on your phone number• Call any phone number

Home operator benefits• Improve customer satisfaction• Provide better service than OTT• Retain voice revenue

End user benefits• Make and receive calls with your mobile phone at

home without cell coverage• Utilize existing Wi-Fi and broadband connection

Operator benefits• Improve customer satisfaction, reduce churn• 5 bars coverage with Wi-Fi • No extra equipment needed (e.g femto))

The Roaming Advantage

2015-2016: The VoWi-Fi Tipping Point

• The Eco System is Ready !

• Network Operators are already embracing Wi-Fi offload

• There is a Symbiotic relationship with VoLTE

• Service Parity with Legacy MSCs including IN services

• An Inherent coolness factor !

• And…
