VoLTE is on the Rise

Source: GSMA

300 VoLTE-

capable devices

480 operators have

commercially launched LTE

networks with 550 forecasted by end 2016.

46 operators in

29 countries commercially

launched VoLTE-HD

118 operators

Industry Stats

Sources: GSMA, Analysys Mason

Annual costs can rise to about

$45 millionin 5 years, for a subscriber base of around 75 million

Typical Tier 1 operator, cost of deploying and operating an on premise IMS solution would be about

$10 million

By 2018, it is expected that about

600 million smartphone users

worldwide will use VoLTE as their default voice service

Understanding VoLTE Interconnect

Challenges

Supported LTE infrastructure

Signaling protocol shift from SS7 to Diameter and SIP

SIP Normalization

Working with the variations in standards IR.34

Pre early call setup

Bandwidth management

Charging and Accounting

Emergency and Priority calls

Multimedia interworking between operators

Voice transcoding

Advantages

Faster call setup

Higher quality voice and video calls, CoS (IPX)

Efficient use of spectrum, releasing extra capacity for data

Optimizes network and service management

Simplifies service delivery

Security based on IPX

Support for GSMA IR-92/IR-94

Leverages IMS core in the cloud

Real-time diagnostics and analytics
