VoLTE, the Trigger Point of the 3rd Wave
Analogue→Digital TDM→IP All IP and FMC
TDM switchs
(1990-2000)
Softswitch
(2000-2010)
All IP and IMS
(2010-2020)
We are here The 1st wave The 2rd wave The 3rd wave is coming
The 2nd wave The 3rd wave
• Driven by:
•Rapid growth of user base;
•Fixed and mobile substitution
• Technology:
•IP Softwtich
• Driven by :
•Enriched end user experience
•Rapid growth of VoFBB & VoMBB
• Technology:
•IMS/RCS

LTE is packet only network, no CS domain, IMS is 3GPP standard voice solution
Voice is basic service even for LTE subscriber;
Voice is main revenue resource for operator
In LTE Era, Operator faces more fierce competition from OTT (Over-the-top)
Operator should provide rich user experience to compete with OTT
Frequency Bandwidth: 5MHz Codec:12.2k AMR Sector Radius: 1KM
3 Times enhancement compared to CS
Key technology is already mature:
IMS based VoLTE/RCS technical solution
RCS based multimedia communication
Advantage compared to OTT:
All IP based E2E QoS guarantee
Telephone number based Subscriber ID
Subscriber is reachable all over the world
Accumulated advantage in voice service:
Trust relationship with end subscriber
E2E customer service and care
Tariff package combining voice and broadband
Key Drivers of Voice over LTE
Short and Mid Term Drivers: Rich voice, challenge OTT
Long-term driver: Unified network, TCO saving
Operators are capable to face competition from OTT

IMS/SRVCC: Voice over IMS over
LTE,handover & roaming to 2G/3G is
supported
CS Fallback: Attached on LTE,fallback to 2G/3G when initial or
receive voice call
SVLTE: Dual simultaneously working
RF module on terminal, data on LTE,
voice on 2G/3G CS

Voice on CS
Voice & Data
on LTE
• Rich voice experience
• Faster call setup than CS
• 3 times spectrum efficiency
• Fast but dirty
• 2-3s longer call setup time
• Plain CS voice experience
• Minimal impact on network
• Higher cost & power
consumption on terminal
• Plain CS voice experience
Huawei Position: Support standard IMS/SRVCC and CSFB option, CSFB is an interim & complementary solution
LTE Voice
Solution
OTT Mode: Rely on OTT Apps for
voice service offering
• No investment on IMS
• Voice revenue goes to OTT
