BUSINESS CASE: • Exploit platform capability to partner with third party service providers • Deliver Rich Communication Services such as video calling to enhance brand, reduce churn CONSUMER EXPERIENCE: • Faster call set up times • Calls in HD Voice quality, with interoperability between HD voice devices • Continuity and ubiquity of quality of service OPERATIONAL EFFICIENCY: • Derive spectral efficiency by refarming spectrum whilst still providing voice call continuity • Simpler operational environment - all IP Vodafone Portugal Deploying in HSPA network Optus Australia Trialling VoLTE in LTE network T Mobile Austria Trialling VoLTE in LTE network Sasktel Canada Deploying VoLTE in LTE network Telus Canada Deploying VoLTE in LTE network China Mobile China Trialling VoLTE for launch Q4 2014 DT Germany VoLTE deployment is planned E Plus Germany VoLTE deployment is planned CSL Hong Kong VoLTE commercial network launch - 05.12.13 PCCW Hong Kong Deploying VoLTE in LTE network Bharti Airtel India Trialling VoLTE Reliance Jio Infocomm India Trialling VoLTE NTT DoCoMo Japan VoLTE deployment is planned Softbank Japan Deploying VoLTE in LTE network Alfa Lebanon VoLTE deployment is planned Tele2 NL Netherlands Deploying VoLTE in LTE network Vodafone Netherlands Studying introduction of VoLTE Yota Russia Deploying VoLTE in LTE network Mobily Saudi Arabia Deploying VoLTE in LTE network StarHub Singapore VoLTE deployment is planned Telekom Slovenije Slovenia Deploying VoLTE in LTE network Telefonica Spain Trialling VoLTE Tele2 SE Sweden Deploying VoLTE in LTE network TeliaSonera Sweden Deploying VoLTE in LTE network Etisalat UAE Deploying VoLTE in LTE network EE UK Deploying VoLTE in LTE network AT&T USA Deploying VoLTE (test markets end 2013) C-Spire USA Deploying VoLTE in LTE network T Mobile US/MetroPCS USA Deploying VoLTE in LTE network Sprint USA Deploying VoLTE in LTE network US Cellular USA Trialling VoLTE in LTE network Verizon USA Deploying VoLTE (target launch 1H 2014 OVERCOME THE APATHY: KEY ADVANTAGES OF VoLTE: IMS IP MULTIMEDIA SUBSYSTEM Standardised definition of architectural framework for control and delivery of IP multimedia services. VoLTE GSMA IR.92 VOICE OVER LTE The set of requirements needed for device and network to support IMS-based telephony services over LTE. CSCF CALL SESSION CONTROL FUNCTION Processes all the IP signalling requests from IMS endpoints via application servers. CSFB CIRCUIT SWITCH FALLBACK Network signalling instructs an LTE-connected device to "fall back" to 2G/3G to make or accept an incoming call. SR-VCC SINGLE RADIO VOICE CALLCONTINUITY Ensures call continuity by maintaining a session as a user moves from LTE to non-LTE coverage. TAS TELEPHONY APPLICATION SERVER SIP application server that supports telephony requirements in the network. ACRONYM SOUP KNOW YOUR VoLTE HD voice deployments, trials © GSA // www.gsacom.com
