EVS is the 1st 3GPP Standard Codec supporting

SWB voice at low bit rates and delay suited for conversational services

Improved Channel Robustness and Error-Resiliency for non-QoS mobile VoIP Calls

NB, WBB, SWB and FB selected modes all in one codec

In-call low-delay WB , SWB and FB Music

Spectral BW efficiency & flexibility for both 3G-CS and 4G-VoLTE calls

Broad range of bit-rates to effectively accommodate various VoMBB

Minimal Network Upgrades as it utilizes existing AMR/AMR-WB LTE Transport Blocks

VoLTE BenefitsDelivering a Richer Communications Experience

Voice over LTE

Blazing fast data

Simultaneous voice & 4G data

Enhanced voice

• High quality HD voice

• Fast call set-up time

• HD voice continuity to 3G

Richer services

• HD Video calling

• RCS, presence, file sharing etc.


Key VoLTE features

RoHC Improves capacity

SPS Improves capacity

Short DRX Improves device power efficiency

TTI bundling Improves UL coverage

SRVCC Provides call continuity

Bearer combinations Allows service concurrency

Domain Selection Dictates device camping policy


Circuit Switched Voice Transition to Richer, Carrier Grade VoMBB

Packet Switched Handoff (PSHO), Single Radio Voice Call

IMS VoMBB: A Differentiated Rich VoLTE – Ubiquity vs. OTT VoIP

VoIP over (HSPA+, DO, WiFi) Driven by VoLTE and

multimode global roaming

2016

Fallback to 2G/3G circuit switched voice (CSFB) used by most LTE

operators while the VoLTE ecosystem is being developed and expanded

2017+2014


Voice Over Mobile Broadband (VoMBB)

• VoMBB is an alternative and efficient method of transmitting traditional mobile circuit switched voice services as packet-switched over 3G/4G mobile broadband and effectively offload such services to voice over WiFi

VoMBB Definition

• VoMBB allows carriers to optimally leverage their IMS framework and manage the flow of mobile VoIP traffic generated by Over The Top (OTT) applications

Ecosystem & Economic of Scale

• VoMBB can potentially open up new models for charging of voice services and even possible relationships between carriers and OTT application developers for mutual benefits

Business Opportunities

• Global VoMBB service revenues increase is estimated to be $3 Billion in 2013 to nearly $103 Billion in 2016

Global Revenues

Benefit of VoMBB Services

Ability to offload Voice Capacity to other

Technologies such as WiFi- Hotspots 2.0

US $/GB: LTE: $4.25, HSPA/HSPA+: $6.25,

WCDMA: $8.70, GSM/CDMA: $12.50

VoLTE with DRX and SRVCC instead of

SVLTE and DRVCC

Management of OTT Services which lack

quality, interoperability, handoff, security
