Overview of RCS and VoLTE

Transcription

1 Overview of RCS and VoLTE David Hutton, Director of Technology, GSMA GSM Association 2011

2 The Voice challenge for LTE LTE is an all-ip mobile network No support for traditional CS domain voice Multiple Proposed Technical Solutions IMS-based Voice ( One Voice ) CS-Fallback VoLGA utilises 3GPP Generic Access Network Over The Top Voice - OTT The risk industry fragmentation Poor customer experience No common implementation ti Economies of scale are lost Threat to Global Roaming

3 The Solution for Voice over LTE The Reality the industry knows where it is going OneVoice adoption as GSMA Voice over LTE (VoLTE) > IR.92. Massive backing from operator and vendor community. Migratory solutions filling the gap between LTE launch and IMS deployment for some operators. VoLTE GSMA PRD IR.92 IMS Profile for Voice and SMS UNI Profile defining the minimum mandatory set of requirements for UE and Network to support for a high-quality IMS-based telephony service over LTE. Based on 3GPP Release 8 standards (and some Release 9 e.g. Emergency call)

4 Current status of VoLTE VoLTE launched in three networks SKT, LG U+ and Metro PCS Many additional commitments to VoLTE for launch during 2013 Device implementation combines VoLTE with Wideband codec, Video, RCS In the meantime, other operators may launch first with CSFB. Delays in SR-VCC capability making CSFB a likely first Voice deployment for many operators. CSFB still viewed as sub-optimal interim solution - improvements in set-up time for CSFB ongoing. PS-handover (VoLTE <-> VoHSPA) may prove to be the alternative to CSFB. Everyone is heading to VoLTE just taking different paths to get there.

5 Rich Communications Services Overview Innovative set of features beyond today s Voice, SMS and MMS technologies RCS Device Modes for telephony:- RCS-VoLTE, RCS-VoHSPA, RCS-AA, RCS-CS

6 What is joyn? joyn is the global consumer facing brand for RCS-e services that will be used by operators Benefits:- Service Discovery displays the services available to be used for any particular contact in the user's address book. joyn is interoperable between mobile operators, which enables the end user to communicate and be connected with anyone. joyn is either available natively in the mobile phone or can be downloaded as an app - without the need for passwords or creating a special account (crossplatform technology). It s just there, it just works

7 joyn Licencing and Accreditation Framework The joyn Logo License Agreement is a promise to only use the joyn logo when the device/platform has successfully completed the minimum i requirements for RCS IOT these requirements are provided in the License Agreement and are applicable for certain device categories (devices, PCs, tablets). GSMA are undertaking this to enable standardised RCS-e compliant services to be brought to market across the whole industry. Client Accreditation and Assurance Network Accreditation and Assurance This approach will mean a high level of assurance of delivering the It s just there, it just works philosophy h inherent as part of the joyn proposition to customers. List of Accredited Operators and Client Manufacturers:

8 GSMA RCS Network APIs API approach in order to expand capabilities, enable new business models, provide mechanisms for differentiated t d services, and significantly ifi reduce time-to-market t t for innovation Available to any developer community independent of the development platform Expose network assets independent of the signaling protocols, network platforms, or access technology Reduces development cost and time-to-market t t for new applications and services Simplifies and fuels wider deployment of existing applications and services Supported APIs:- Network Address Book, Presence, Messaging (SMS/MMS), Chat, File Transfer, Call, Video/Image Share, OAuth Framework, Capability Discovery
