WebRTC can support a seamless communication experience in the connected world allowing consumers to communicate when and how they choose
“Communication is no longer limited to phones and flows like water across multiple platforms and devices” Josh Silverman, former CEO of Skype
HTML5 simplifies developing and delivering apps across this range of devices It provides a consistent app experience regardless of the device/device vendor The majority of these connected devices and resident apps can benefit by integrating RTC WebRTC is the means to integrate RTC into this collection of devices and apps

WebRTC can realize the multi-access, multi-device, multi-screen vision of IMS
LTE, Fixed BB, 3G, Ckt
1. 4G communications provides voip, video, messaging, and other RCS services over macro wireless LTE access.
a. WebRTC gives VoLTE/4G comm subscribers the ability to access and use their IMS services from other devices over multiple access technologies – including PCs, tablets, TVs, etc. over fixed and wireless networks
b. WebRTC allows VoLTE/4G comm subscribers’ friends and families to use IMS services – extending the reach of advanced IMS features before full interoperability between IMS service providers is achieved.
2. WebRTC can be provided on PCs, tablets, and other non-mobile devices over 4G access technology
– Leveraging LTE capabilities to take advantage of QoS and ANDSF may be an option
3. WebRTC can be provided on mobile phones over 4G access technology
– Firefox OS handsets available 2013 with circuit voice
MULTIPLE WAYS WEBRTC CAN EXTEND 4G COMMUNICATIONS
Extends VoLTE IMS subscription services access to the web browser. Support originations and terminations.
1. Basic functions needed: a) VoIP, video call/share, messaging, inbox
b) SIM-less authentication
c) Common network addressbook (multi-screen/multi-device)
d) Presence
e) Regulatory services (not shown)
f) QoS (not shown)
2. Additional functions: a) RCS – e.g. File transfer, image share, etc.
b) Collaboration beyond RCS – e.g. whiteboard, document share, screen share.

1. Basic functions needed: a) VoIP, video call/share, messaging
b) Guest IMS subscriber support
c) Regulatory services (not shown)
d) QoS (not shown)
2. Additional functions: a) RCS – e.g. File transfer, image share, etc.
b) Collaboration beyond RCS – e.g. whiteboard, document share, screen share.
Additional RCS
Beyond RCS
1. Laptops, tablets, others (e.g. cars) – Access to webRTC apps – QoS support
2. Other devices (e.g. concierge kiosk, ATM, etc.)
– WebRTC provides device app-specific communications

2. Additional functions: a) ANDSF (3GPP standards for access and APN
selection) b) Multiplexing (actively discussing in standards) c) RMCAT Congestion control (starting discussion in
standards)

• WebRTC is an exciting new HTML5 client technology enabling IP communications innovations on multiple device platforms integrating into millions of websites and web apps.
• WebRTC can extend 4G communications in multiple ways: 1. Web extension
a) Extend access to IMS comm services beyond the VoLTE smartphone to PCs, tablets, TVs, etc. b) Allow non-IMS subscribers to join a conference via a webRTC URL link
2. PCs, tablets, non-traditional devices, and other non-mobile devices on 4G 3. Mobile phones
a) HTML5-based OS handsets b) HTML5-enabled smartphones
