4 What is WebRTC? WebRTC is a W3C standardiza,on ac,vity (with support from IETF) that enables web browsers with Real- Time Communica,ons capabili,es via JavaScript APIs. It allows rich, high quality applica,ons to be executed in the browser using JavaScript APIs and HTML5, without the need for any other na,ve applica,on or plug- ins. Minimum requirements for a WebRTC enabled applica,on are: 1. A browser supporjng WebRTC WebAPIs: GetUserMedia PeerConnec,on MediaStream DataChannel 3 2 Web Server WebRTC Service PlaMorm WebRTC Gateway PSTN 2. A Web based plaworm with APIs enabling establishment of SRTP/SCTP connec,ons between one or more WebRTC- enabled devices and other voice/video clients or services. 3. A WebRTC applicajon which uses JavaScript to access WebRTC APIs exposed by browsers and WebRTC service plamorms 1 Webapp JavaScript Browser Device Internet SRTP / SCTP Webapp JavaScript Browser Device AT&T Intellectual Property.

7 WebRTC impacts on IP messaging Key disrupjve facets of WebRTC: Social Media Client ubiquity No need for a messaging client to be downloaded Unified communicajons Audio, Video and Data channels Integrated Web experience no need to switch between the app and messaging client Messaging Gaming Web Apps ALL in the browser!

8 WebRTC OpportuniJes for Network Operators 1. Integrated charging Users already have mobile service. WebRTC with session- based charging can be added onto exis,ng service plans. 2. Bundling Messaging APIs can augment WebRTC apps with RCS and other messaging services developers already know and implement. 3. Reliability QoS can provide assurance to users and priority services (enterprise, emergency, law enforcement, ehealth) that a WebRTC service will work as well as they need it to. Session Based Charging Bundle APIs QoS Further opportunijes can be realized through standards for: WebRTC profile of OMA RESTful APIs Standardized use of OMA Push for WebRTC Anonymous Customer Reference (ACR) usage as calling/called party Inter- operator directory and rou,ng capabili,es Inter- operator charging and billing including support for Third Party WebRTC signaling gateway into IMS QoS RESTful API WiFi offload via Network Info API for Web apps AT&T Intellectual Property.

10 Key Conclusions WebRTC will be a disrupjve technology, for sure, but It s not so simple to design a pure OTT service with Ubiquitous service access: any device, anywhere Interoperability with exisjng services PLMN levels of quality and reliability Even so OMA needs to help drive standards that complete an end- to- end WebRTC service ecosystem, fully integrajng it with exisjng voice, video, and messaging services AT&T Intellectual Property.
