VoLTE offers Last Chance for Operators to revive its
Service Offering
VoLTE is the
‘premier’
communication
service over 4G
LTE is going strong:
LTE -> LTE-A (pre 5G) -> 5G
Voice will onboard LTE
between 2016-2020

Operator Challenges for International VoLTE
29/06/2016 BICS Restricted 7
Operators have multiple challenges to deploy
VoLTE internationally:
Technical Challenges:
• International interconnects TDM to IP migration
• Upgrade infrastructure - NNI
• Carrier ENUM support
• Devices compatibility
• Multiple Roaming solutions
• eSRVCC support
Financial Challenges:
• Lack of Business Case
Strategic Challenge:
• Should Operator define its role as smart pipe?
Competition:
• OTTs are offering advanced communication services with global
interoperability and fast Time-to-Market
Key Success Criteria
29/06/2016 BICS Restricted 8
User should have same enhanced
communication experience when at home
and while roaming
International VoLTE is a two step process:
• Inter-working between Operators’
networks
• Roaming in other networks
Operator and IPX-P collaboration can enable services with global reach:
• Offer integrated Voice – VoLTE and WiFi Calling
• Offer Video over LTE
• Offer RCS
