IMS World Forum Pre-Conference Workshop:
A New Wave of Communication
IMS and WebRTC.
IMS may not be everyone’s ‘favorite cup of tea’,
but it’s there in most networks. Put simply, for any
operator migrating their services to IP, and in
particular voice, what choice do you have?
Today, none, but we can start preparing for a
dual-platform world today.
Agenda Part 1
• 13.45 Introductions
• 14.00 IMS and WebRTC: What does it mean and where is it going? – Alan
o Overview of current IMS status
o Deployments based on global survey run every 2 years
o Ecosystem based approach to developing new services
• 14.30 Bridging IMS into the 21st century with Open Source software –
o Project Clearwater is IMS re-imagined for the cloud.
o Keeping aligned with the objectives of network functions virtualization
and enables network operators to compete far more effectively with OTT
Agenda Part 2
• 15.00 Bridging the network divide – OpenCloud
o Adapting signaling solutions to enable operators to take legacy services forward into IMS
o Harmonized legacy-IMS service layers to reduce the barriers of service innovation
• 15:30 Afternoon Break
• 15.45 Rich Communications and WebRTC – Solaiemes
o WebRTC is the perfect tool to evolve the telco communications
o Telco comms available ubiquitously also allowing number based telephony with OTT
• 16:15 Bridging the Internet and IMS with WebRTC – Oracle
o Application authentication, control, and network synchronization
o Rapid application integration and interworking with existing systems
o High capacity media handling for NAT traversal, encryption, and transcoding
Agenda Part 3
• 16.45 Apps in your calls – Where IMS differentiates – Tropo
o Differentiating using core IMS capabilities to build a new class of apps in
o Ameche enhances comms by enabling developers to mash-up telco
capabilities with cloud services
• 17.15 Wrap up discussion and Q&A on the new wave of innovation
• 17.30 Close of workshop
IMS and WebRTC:
What does it mean and
where is it going?
• Where is IMS?
• Where is WebRTC?
• Why is IMS working on WebRTC standardization?
• What should you do?
By Customers Impacted Today
Let’s Face it The Web has Won
• WebRTC is the future
• Drastically lower operating costs vs. traditional network
• Rich communication environment means real communications app
• WebRTC goes where your customers are going
But we’re not there yet, IMS is still relevant
• Gateway To The Old World, When Necessary
• Re-use existing Deployments & Investments
• Enhance existing service offerings (short-term)
• Enable legacy customers in new WebRTC world (long-term)
• IMS goes where your customers are today
Why add WebRTC to IMS
• Telcos are interested in WebRTC because:
o Identity Providers.
o API exposure and QoS supported TURN-as-a-Service.
o OTT strategies that involve WebRTC
o WebRTC-based access to the existing legacy infrastructure/services.
• WebRTC brings IMS to any device that has a WebRTC capability.
o WebRTC allows operators to untie their services from physical devices.
• Given the above, the 3rd Generation Partnership Project (3GPP) started
the technical definition of a solution for a WebRTC client to access to
IMS networks through the Internet.
Arghhh! Yet more boxes and wires!
WebRTC IMS Client (WIC)
WebRTC Web Server Function (WWSF)
P-CSCF enhanced for WebRTC (eP-CSCF )
IMS Access GateWay enhanced for WebRTC (eIMS-AGW)
What’s missing? MUCH!
• Many items are further study in the specification or omitted
• Media multiplexing - running several audio/video streams on the same
address:port is not allowed
• QoS is supported, but over the internet connection is impossible
• User identification authentication for further study
• WWSF to eP-CSCF communication – this mechanism is not defined but could be
user or the eP-CSCF could use the WWSF as authentication/identity server
• Trickle-ICE – future study
• Decomposing the eP-CSCF – many vendors are implementing WebRTC gateway
products independent of their P-CSCF elements
• No explicit mention of TURN support
• Guest access for non-subscribers is not covered
By the numbers in 2013
• These numbers are an average of inflated vendor claims and operator claims on
what was actually spent. Note many deals announced of value X end up X/2
• CSCF and SBC markets finally overtook gateways and softswitches in revenue in
2013, been threatening for 3 years
• Worldwide carrier VoIP and IMS revenue reached $3.5B in 2013, up 30% from
2012, with LTE and VoLTE driving growth.
• US, China, and Japan had most of investment
• Expect 2014 to be a down year given the VoLTE delays and 2013 “hero POs”
CSCF Rev reached close to $1B in 2013
• Huawei / Ericsson top 30%
• NSN / ALU 20% / 10%
• RCS on IMS DOA (Dead on Arrival), simply be used for interop, see
• GSMA needs compete overhaul not reacting to changes in market
o See ‘beard and sandal’ problem
o Does not understand market we are moving towards – it’s the web
Voice App Server Revenues Growing
• $500M, growth of about 25% pa
• Importance source of service innovation
• Difficult to charge a premium.
• Some residential licenses have been sold for IMS networks at $1 per
line (equivalent) and less.
• Average is about $1.75, drop to $1.50 over next 3 years.
• QoS matters full stop!
• Regulation can not be changed!
• New services have negligible revenues!
• A2P?? What’s that! Its negligible?
• Innovation is for third parties!!!
• We’re going to monetize our APIs!!!
We’re killing our industry
