VoLTE Background and extensions Dan Warren, Senior Director of Technology, GSMA© GSM Association 2011

VoLTE – to date History – „One Voice‟ profile handed to GSMA and became IR.92, the UNI SIP Profile for UE to IMS network. – First version of IR.92 completed April 2010 - continuing improvements via GSMA CR process. Roaming and Interconnect (and in particular the combination of the two), have proved difficult to complete. – Technically optimal approaches do not take into account the need to interwork or fall back to existing Circuit Switched techniques. – Commercial requirements further restrict the technical solution. – Work in 3GPP initiated to address the requirements – RAVEL work item. Now, work to extend beyond the original VoLTE service has spawned new threads of work.

Current status of VoLTE VoLTE service expected to appear first in North America during late 2011/early 2012. – Device implementation combines VoLTE with Wideband codec, Video, RCS. – Baseband implementation but expected to have OS accessibility to some IMS- based features. In the meantime, Europe and Asian operators likely to 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 - improvements in set-up time for CSFB being proposed in 3GPP. Everyone is heading to VoLTE – just taking different paths to get there.

VoLTE Extensions UNI profile Over 3G The original OneUnder approval Voice profile with Under approval enhancements 3G access Terminal to Network LTE access Network To be enhanced once 3GPP work is complete IMS with CS voice

IR.64 – IMS control for all voice callsService Centralization in the IMS: IMS “controls” both circuit and packet voice calls Two main features: T-ADS  Terminating Access Domain Selection CS IMS – Determine whether to route terminating PS call to CS or PS access  Single Radio Voice Call Continuity SRVCC CS – Maintains IMS call control when moving IMS from LTE to 2G/3G CS PS

IR.94 – Video over LTE Normal call with voice and video Early media mono or bidirectional (video announcement, video ring “tone”, …) Network Network Multi party call with voice and Dial-in to external video conference video system Network Network Video switching Video switching

IR.58 – extension of IR.92 to 3G HSPA bearer Minimum mandatory set of 3GPP features that a wireless device and network are required to implement in order to guarantee an interoperable, high quality IMS-based telephony service over HSPA  IR.58 is very similar to IR.92 (IMS profile for IR.92 IR.58 voice and SMS over LTE) and inherits as much as possible from IR.92, in particular: IMS features IMS features  The document framework, with similar IMS IMS corresponding section numbering whenever possible media media  The document contents, with a simple reference to LTE radio HSPA radio capabilities IR.92 when the content is agreed to be equivalent capabilities Bearer Bearer management management Other Other functionalities functionalities

How to prove it works - IOT IMTC SuperOp, May 2011 – Handset focus but struggled with lack of handsets available from vendors. – IMTC hosting a VoLTE webinar – 30th Nov. MSF VoLTE Interoperability Event, September 2011 – Hosted by Vodafone and China Mobile. – Demonstrated calls, interconnect and roaming. – Detailed results announced 8th November. – Planning further IOT on VoLTE with GSMA and ETSI for 2012.
