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

Data on LTE

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

LTE Voice Solution Options & Huawei Position


• GSMA IR92.30 (VoLTE Profile)

• 3GPP R10 (MMTel、ICS、eSRVCC、PCC）

• GSMA RCS 2.0/3.0/4.0

• Clear Roadmap from major supplier
