    • The Voice EvolutionVoLTE, VoHSPA+, WCDMA+ and Quality EvolutionApril 2012
    • Qualcomm is a Leader in Wireless 2012 2013 2014 2015+ Rel-8 Rel-9 Rel-10 Rel-11 & Beyond LTE LTE Advanced (FDD&TDD Commercial) Rel-7 Rel-8 Rel-9 Rel-10 Rel-11 & Beyond HSPA HSPA+ HSPA+ HSPA+ (Commercial) (Future) Advanced WCDMA WCDMA+ Voice Efficiency M2M Efficiency CDMA2000 1X 1X Advanced (Commercial) (Future) Rev A Multicarrier H/W Upgrade Phase I Phase II EV-DO EV-DO Rev. B DO Advanced (Commercial) (Commercial) (Future) 802.11 g 802.11 n 802.11 ac/ad Wi-Fi Wi-Fi (Commercial) (Future) Commercial2 Note: Estimated commercial dates. Created 04/18/2012
    • Evolving Voice for More Data, Better Quality, Richer Experience Qualcomm: Comprehensive Voice Evolution Leadership  1X Advanced, WCDMA+, IMS VoIP over LTE, HSPA+, EV-DO, and seamless transitions 2G/3G Provides LTE Voice Today & Future VoLTE Fallback  CSFB widely deployed, future VoLTE needs SRVCC to ensure seamless voice VoLTE with VoHSPA+ Ensure Rich Voice Everywhere  Ensures a seamless and consistent rich voice user experience WCDMA+: More Efficient Voice to Support More Data  Triples WCDMA circuit switched voice spectral efficiency Qualcomm Enables The Best Voice Experience  Leading Voice Quality Technologies for 3G circuit switched voice, IMS VoIP and OTT VoIP (HDOn, Calliope Fluence..)3
    • Circuit Voice Has A Long Life During The Transition to Richer, Carrier Grade VoIP IMS VoIP: Rich Voice – Ubiquity vs. OTT VoIP VoLTE Timing is Operator Specific VoIP over HSPA+ Driven by VoLTE Fallback to 2G/3G voice (CSFB) used by most LTE operators while the VoLTE ecosystem is being developed and expanded Proven Circuit Voice: High Quality, Reliable, Ubiquitous1 WCDMA+: Long life of HSPA+ means long life of WCDMA 1X Advanced Commercial (1H 2012)4 1Thanks to soft handover, proven interoperability and 10+ years of 1X/WCDMA optimizations. OTT=Over-The-Top, voice just like any data service without Quality of Service
    • Qualcomm: Comprehensive Voice Evolution Leadership 2012 2013 2014 2015+ 2020+IMS VoIP: Evolving to a Richer Carrier Grade Voice Service 2G/3G Provides Voice VoLTE Packet Handover VoIP over HSPA+ (EV-DO) SeamlessTransitions CSFB1 SRVCC2 WCDMA WCDMA+ 1X 1X AdvancedCircuit Switched Voice: Evolving To Support More Data Blue: Qualcomm Technology Leadership5 1CSFB: Circuit Switched Fallback. 2SRVCC: Single Radio Voice Call Continuity to enable handover to WCDMA/1X/GSM CS voice outside VoLTE coverage.
    • 2G/3G Provides LTE Voice Today —And Future VoLTE Fallback 2G/3G Provides Voice VoLTE—IMS VoIP over LTE CSFB1 to WCDMA, 1X or GSM Ccommercialization with SRVCC1 voice is commercial since 2011. starting in 2013, maturing in 2015 Today: Fallback to VoLTE: Fallback1 to 2G/3G, 2G/3G for all or handover to VoHSPA+, voice calls outside LTE coverage LTE (FDD or TDD) 2G/3G Voice & EV-DO/HSPA+ Data Voice Continuity and Global Roaming6 1SRVCC: Single Radio Voice Call Continuity. CSFB: Circuit Switched Fallback.
    • 2G/3G Voice Fallback (CSFB) Commercial Since 2011 and Widely Deployed SIMILAR CALL ~1s SET-UP TIME AS TODAY ~ 0.5 s (MOBILE ORIGINATED OR TERMINATED CALL) Baseline WCDMA (R99) Set-up time Enhanced CSFB1 R9 CSFB2 (R8) (R9) RELIABILITY ON PAR LTE (DATA ONLY) WITH TODAY’S LTE NETWORKS Multimode Single Radio Device WCDMA, GSM,1X 1Redirection without reading the non-mandatory system information blocks ‘SIBs’, 1xCSFB for 1X is also redirection based in R8.7 2System information provided directly in a LTE redirection message to speed up the transition, aka ‘SIB tunneling”. Enhanced R9 1xCSFB is Handover based
    • SRVCC Ensures Seamless Voice Continuity 2012 2013 2014 2015+ VoLTE on Mature VoLTE w/ par with CS Interoperable SRVCC Voice Quality VoLTE LTE VoLTE Single Radio Voice Call Continuity (SRVCC) enables handover to 2G/3G Voice Outside VoLTE coverage 2G/3G VOICE CIRCUIT SWITCHED LTE Multimode Multimode devices ensure Single Radio Device global roaming from day one IMS VoLTE IMS can expand to support other With VCC VoIP accesses (HSPA+, EV-DO etc.)8 1SRVCC for VoLTE to 2G/3G circuit switched voice is defined in 3GPP Rel-9, with enhancements in Rel-10
    • World’s First SRVCC Handover by Qualcomm and Ericsson (Feb 2012)9
    • Different VoIP Models Will Co-Exist OVER-THE-TOP VOIP OPERATOR 3RD PARTY PROVIDED (BEST EFFORT) PROVIDED SERVICE SERVICE Opportunity To Offer Quality Of Service IMS/RCS Operator to OTT VoIP Provider 3rd party VoIP Client Client Interoperable, ubiquitous May not interoperate with rich voice solution1 other VoIP solutions Variable Quality, Dependent Carrier Grade Voice on Network Load10 1IMS/RCS based VoIP is the industry solution for carrier grade voice, to enable a ubiquitous VoIP solutions .
    • VoLTE with VoHSPA+ Ensures Rich Voice Everywhere Integrated Presence Enhanced contacts with presence Integrated messaging, chat, synch. etc Enriched Voice/Push to Share Share multimedia content during call, such as video, pictures, files etc. Video Telephony With full interoperability Rich Services Initially VoLTE with VoHSPA+ Ensures Limited to VoLTE Coverage Consistent and Seamless Handover to WCDMA/GSM circuit switched voice Through Single Radio-VCC Rich Voice Experience11 Based on Rich Communication Suite (RCS), an industry effort leveraging IMS to providing mobile phone services.
    • VoLTE and HSPA+ VoIP Profiles Defined TO ENABLE INTEROPERABILITY, SCALE AND ROAMING Common User to Common Network Common User to Network Interface to Network Interface Network Interface User to IMS User to Network IMS Network (Operator A) (Operator B) Interfaces Interfaces GSMA VoLTE and VoIP over HSPA+: • Defines common voice, sms service profiles, bearers etc. • Defines minimum support level (IMS, LTE/HSPA+, EPC) VoLTE ROAMING AND INTERCONNECT EXPECTED 2014 AND BEYOND12 VoLTE: GSMA PRD IR.92 – “IMS Profile for Voice and SMS” completed in 2011, HSPA+ profile defined in IR.58 completed early 2012. Additional PRD on IMS roaming defined.
