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.
–  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

Voice / video / browser view context shared
–  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
–  Seamlessly blends multiple modes of
communication & diverse information
–  Lowers transaction times
–  Higher end-customer satisfaction
–  Leverages existing IDs
–  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
AppApp
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

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

§  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

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
