1 Benefits of VoLTE/RCS to Carriers and Subscribers
Quan Choi Sr. Manager Product Strategy

2 What is RCS? Rich Communication Services (RCS), provides Mobile Network Operators with a means of transitioning circuit services (voice and SMS) into an all-IP and LTE world Latest version of RCS is Release 5.1, bringing in support for IP Voice, IP Video, and Location Sharing Voice over LTE (VoLTE) is an RCS service Enabled by an IMS platform Content Sharing Video sharing picture sharing File transfer Location sharing Chat 1:1 chat Group chat Enhanced Address Book Picture/ Portrait Link Status text Availability Location Information Time zone Voice and Video VoLTE (with lower latency) HD Voice IP Video Call Video Conferencing Video Messaging/Video VM Messaging SMS MMS IMS platform

3 Challenges in Implementing VoLTE
Emergency services SRVCC Service Continuity Complexity

4 Emergency/Regulatory Services
E911 over VoLTE network CMAS over LTE Wireless Prioritized Services on LTE CALEA for lawful intercept

5 3GPP 3GPP2 Voice Call Continuity AT&T and T-Mobile
Launched with eSRVCC Call remains connected when mobile moves out of VoLTE network Network and chipset support commercially available 3GPP2 Verizon depends on complete nationwide LTE coverage Call will drop when device moves out of home VoLTE network Very costly for network support and no device support

6 Service Continuity AT&T Fine Print
“The following features/services are currently incompatible with HD Voice service: prepaid service, Smart Limits, Ringback Tones, and OfficeDirect and OfficeReach (for business customers).” Other services that may differ between IMS and legacy network Conference calling (number of connections could vary) Video calling and conferencing Other enhanced messaging services Simultaneous voice and LTE

7 Why not VoIP over LTE? Features on the device and RAN QoS and GBR
Call quality unaffected by congestion QoS and GBR Battery life savings Maximized eNodeB resource utilization Discontinuous Reception (DRX) Reduced latency Less error Robust Header Compression (RoHC) for RTP profile Optimizes for fixed interval transmissions, such as VoLTE Reduced signaling overhead Semi-Persistent Scheduling (SPS) Optimizes cell edge coverage on the uplink Reduces signaling overhead Reduces error and latency Transmission Time Interval (TTI) Bundling Features on the device and RAN

8 VoLTE Status on Tier-1 Carriers in North America
VoLTE Launched nationwide in September 2014 Supported on GS5, LG G2, and iPhone 6 Part of their Advanced Calling 1.0, with VoLTE and video calling (except on the iPhone) No SRVCC Move off of CDMA ASAP VoLTE launch in May 23, 2014 with HD Voice 3 in limited market with one device Support SRVCC Video calling support likely to follow Verizon in 2014. Other RCS feature, such as enhanced messaging to follow Expect VoLTE launch in 2015, market by market Currently support HD voice through 1x-advanced Very limited deployment RCS support via Jibe in 2014 VoLTE launch in May 22, 2014, with HD voice, completed national deployment in July – Currently, four devices supported Support SRVCC They will likely continue to support “Joyn-like” RCS services, but will deploy full RCS services such as video and enhanced messaging Mention that Sprint is doing Jibe for RCS. With AT&T to follow.

9 Benefits to Carriers Improve current offerings
Better voice experience to drive usage Text and MMS improvements New offerings Compete with competitors as they start offering the new RCS features Opportunity to offer new products that can increase ARPU New revenue streams with APIs into RCS services (Think WebRTC) Drive data usage Video services and content sharing will use more data Increase the perceived value of the data services Compete with OTT Better experience with LTE network support Ease of use, communicate via phone number Trusted and reliable, offered by the user’s service provider

10 Customer Benefits Better voice experience
HD Voice Quicker call setup time Simultaneous voice and LTE Enriched Services using existing phone number Video calling and enhanced messaging Ease of use, communicate via phone number Reliable and supported by the carrier No change to billing Voice and SMS charged in the same way Other services, such as video and enhanced messaging charged as data

11 Real Benefits to Carriers
Lower OpEx and CapEx through a single network Offer competitive services and products to reduce churn Reduce the risk associated with drastically reduced pool of CDMA carriers Achieve device cost savings from eliminating CDMA royalties and larger, more uniform device ecosystem Open up more potential roaming partners

12 End state for VoLTE Interoperable services for VoLTE/RCS
Similar to when carriers had to encourage adoption of SMS/MMS End-to-end inter-carrier HD voice and RCS Interoperable services for VoLTE/RCS Reuse spectrum currently used for circuit Carrier aggregation to increase LTE capacity Take advantage of LTE’s spectral efficiency Refarm spectrum from legacy networks Tighter partnerships with developers to create new products that take advantage of carrier assets Converged communication services Build up new services on IMS for new offerings Voice over WiFi that offer telecommunication over multiple devices using the user’s number Multi-device telephony services Extend beyond cellular networks through IMS
