WebRTC Opportunities/Use cases IMS Deployments

Web Phone

Web Collaboration

Vertical Industries


IMS Web-Phone Environments: Traditional IMS Connection with VoIP Services

§  User benefits –  Allows remote access to telephony features

anywhere in the world –  Easy alternative when phone is lost/dead –  Avoid roaming or multi-SIM use

§  CSP benefits –  Differentiating feature –  Increases usage of CSP’s network –  Potential new revenue


Web to IMS interconnect Environments: Comms as a Service – Social, Gaming, Etc.

§  User benefits –  Access the ~6B+ users on the PSTN –  Lowers barriers to entry (everyone already has a

PSTN phone)

§  Web service provider benefits –  Securely connect WebRTC calls to the PSTN –  Add core-network protections to all traffic

WebRTC enabled web-site

WebRTC Signaling

SRTP

IMS

RTP

SIP


Enable RCS – Finally! Environments: Mobile SPs

§  User benefits –  Allows remote access to RCS features anywhere

in the world –  Seamless use of comms in any environment –  Enhance RCS with web-based features

§  Service provider benefits –  Differentiating feature –  Increases usage of SP’s network –  Potential new revenue

Extend RCS/joyn services anywhere on the web


New WebRTC Opportunities/Use Cases

Web Phone

Web Collaboration

Vertical Industries


Web Collaboration: Conferencing Environments: Hosted Conferencing Services

§  User benefits –  Easy to add “click to dial” to meeting invites –  Integrates with web-based collab tools –  No browser compatibility issues –  Toll-free audio

§  Service provider benefits –  Augment PSTN-only conferencing services –  Easy deployment & modification

Signaling over WebSockets


Web Collaboration: Unified Communications Environment:Enterprise/Business

§  User benefits –  Provides UC on any device with a WebRTC-

compatible browser –  Seamless & secure remote worker access via

secure WebRTC methods

§  Enterprise benefits –  WebRTC-enable existing enterprise UC system –  Allows for browser-based UC independent of UC

client vendor –  Doesn’t require a thick UC client to be installed &

maintained

Third-party UC client apps

UC client apps on Tablets, PCs, Smartphones

Agent

ACD/ PBX

CRM

WebRTC-enabled website page

Voice / video / browser view context shared

§  User benefits –  Connect immediately to an agent (no IVR) using

the browser’s media capabilities –  No more click-to-call or call back required –  Use computing device as a phone

§  Enterprise benefits –  WebRTC embeds RTC capabilities directly into

web pages –  Browser context (page view) info can be shared –  Lower cost and enhances customer service

Cost Savings: Overall savings of $17M per year over a 5 year period on communication and marketing costs


Vertical Industry – Real Estate Environments: Business Focused Service Providers

§  User benefits –  Seamlessly blends multiple modes of

communication & diverse information –  Lowers transaction times –  Higher end-customer satisfaction –  Leverages existing IDs

§  Service provider benefits –  Leverages CSP brand –  New value-added revenue stream

What is WebRTC Missing WebRTC/IMS Chasm

Current WebRTC

§  Security –  Identity, authentication and authorization

–  More user name and passwords

–  Network Denial of Service

§  Reliable network solutions –  Lose sessions on browser refreshes or network issues

–  Lack of support for large networks with many sessions and many connections

§  Interoperability –  Between networks

–  Browser and devices

–  Voice and video media

–  Policy, charging, or internet traversal


WebRTC Challenges: Security

Server

Telco ID Web ID

•  No unified identity management •  Requires web to network

integration •  No multi-connection support •  No overload protection - DoS •  No network-level authentication •  All traffic treated the same


WebRTC Challenge: Reliable Network Solutions App has no Control Outside of Browser or Over the Network

App App

Failure! Reconnect?

App

Handover?

•  Browser issues •  Refresh •  Surfing and tabs

•  Network issues •  Weak signal •  Disconnects

•  No network handoff


WebRTC Challenges: Interoperability

Server

•  Network: •  NAT message routing •  Slow congestive encryption •  Connections to IMS, VoIP, ..

•  Browser/Device compatibility •  Poor or no codec transcoding •  Policy, charging


Agenda




§  Summary


WebRTC Session Controller Overview

§ Manage and control WebRTC: –  Signaling –  Media

§ Connect Web to Networks –  Enables WebRTC deployments in IMS &

enterprise environments –  Powerful signaling engine –  Scalable WebRTC media support –  Focus development on clients for rapid

service creation

WebRTC Client Applications


Security – User Identity, Authentication Standard Web-based or Telco AAA Mechanisms

Identity

Network

WebRTC

Attack

§  Client identity/authentication - OAuth §  Coordinates identity across multiple sessions §  Telco/enterprise authentication mechanisms §  Network identity - encryption keys & network

authentication §  Prevents network overload/DoS §  Traffic prioritization maintains normal service

to valid users


Reliability – Failure/Recovery Persistent Sessions, High-scale Signaling & Media

N+1 Stateful HA Scalable Clusters

OCWSC OCWSC OCWSC OCWSC WebRTC WebRTC

reconnect § Rehydration – persistent session, re-

establish connection –  Intermittent network connectivity –  Browser crash or reload

§ Highly-scalable software-based SRTP termination

§ Distributed high available signaling and media architecture for carrier-grade scalability


Interoperability – Media Intelligent Media Routing

Web App Web App

Network Anchored

Media

WSC

P2P § Conditional media anchoring

–  Peer-to-peer if a media path exists –  “Anchors” media if no path exists –  Preserving/augmenting ICE and DTLS –  Based on WebRTC SDPs

§ Dynamic media release improves scale & bandwidth allocation

§ WebRTC media to network interworking –  Encryption –  Codec transcoding & mediation IMS


Interoperability – Any Device/Any Network

§ Network handover –  Roaming between networks –  Optimal use of bandwidth

§ Device handover –  New interface –  New IP –  Update media address to peer

Rehydration Maintains Session Between Devices or Networks

Interoperability - IMS, Encryption

§  Highly adaptive WebRTC to SIP/IMS –  Data manipulation –  Process orchestration

§  Application/IMS policies –  Policy and Charging Rules Function (PCRF) :

message handling, codec enforcement, application black/white lists, session limits, etc

–  Media policy support for bandwidth, signaling and media resource allocation

–  Broadband policy management integration with PCRF
