4. EXPECTATIONS
 Honest & realistic dissemination of status quo from 1st hand
 Deployed RCS 5 in H1/2014
 Go-live 30. June 2014
 My role: local technical manager for design and implementation
 This presentation is going to be subjective in parts
 Don’t judge me on that – this is why I am here 
 Experience with IMS, various RCS deployment options, messaging strategies in ST
 Joyn as service needs to do move forward quickly, I will summarize on our fast execution & seen future potential
 Focus on a bit of “How”, a lot of “What’s could be next” – not on “Why”

5. HOW?
HOSTED JOYN SERVICE IMPLEMENTATION IN SLOVAK TELEKOM
 Hosted RCS 5 (Blackbird) service provided by Jibe Mobile
 No local NT implementation (no IMS/SBCs etc.)
 Private cloud connected via public Internet
 Jibe hub for interconnection
 No local interconnection
 Jibe hub provides technical interconnect with all Jibe clouds
 Offers standard NNI
 Launched with full set of services on localized Android and iOS apps
 Messaging, file transfer, location share
 High definition voice & video (much better quality than telephony)
 Go live and operation without major hick-ups or failures
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 5
Bottom line
The implementation and joint
work with Jibe was a success.

6. PRO’S & CON’S OF CLOUD DEPLOYMENTS
HIGH-LEVEL
 Fast
 Cheap
 None
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 6
PRO’S CON’S

7. PRO’S CON’S
PRO’S & CON’S OF CLOUD DEPLOYMENTS
DETAILED
 No or insignificant CAPEX, OPEX driven
 Risk free: Can be killed early if KPI’s not met
 All in one integrated solution (in our case)
 Simpler interconnect
 Easier accreditation
 Jibe platform has much more features than usual
local on-IMS deployments
 No local IMS integration, deployment etc.
 No local IMS deployment
 VoLTE dependency (multiple “IMS”)
 Regulatory or legal challenges (e.g. LI, data)
 Large scale deployments may be more expensive
 Potential vendor lock-in (UNI for apps, infrastructure)

8. LOOKING BACK TO 2012
POINTS I RAISED LAST TIME AT THIS EVENT
“
 joyn as “chat for mobile phones” is not going to convince alone
 RCS as a platform may enable interesting use cases, if the concept is done right
 joyn as platform/enabler not a bad idea as such, but it is not the new SMS!
 What can Telco’s do once they have IMS or RCS infrastructure (for whatever reason)
 Wrong: Look at what we can do with it. Create need or technical motivation.  Joyn
 Technology driven services and features are wrong!
 Northbound integration of IMS service layer should not be an option, but a must!
 … and should be done with Web 2.0 technologies/protocols
 Integration is important (internally as well as opening for external access)
“
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 8

9. WHAT’S NEXT?
 Joyn as a service started “not too successful”
 “Too little, too late” – we all know about that, no need to repeat
 Time moved on – simply put: The world is different in 2014!
 Joyn as a platform may have a potential
 That may be able to help the service
 This is a case study partially taking our innovative platform as an example
 It hopefully encourages others that got Joyn (one way or another) to quickly stop lamenting & see what to do next
 Reach small fragment of customers that has Joyn, but much more importantly expose new functions
 May not be best or cheapest option, but better than not progressing at all
 May bring up to date APIs, integrated with some back-end systems

10. ONE PROBLEM WITH JOYN, AND HOW TO WORK AROUND IT
UNIVERSAL IS GOOD, UNLESS YOU NEED BETTER
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 10
GOOD BETTER

11. WEBRTC TO THE RESCUE
 No.
 Maybe…
 … but not really …
 … and not only!
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 11

12. “BETTER” SOON TO BE THE DEFAULT
WEBRTC CONTRIBUTES TO THE EVOLUTION
 WebRTC is not so much about technology, but “embedded contextual communications” in the web/an app
 No ubiquity needed
 When I am on amazon.com I do not expect to be able to talk to Billa or the police through that website
 When I am inside the IKEA app I do not expect to order a Pizza (maybe meat balls though )
 Value shift from solving connectivity in the 1900s to solving actual problems
 I am connected to a service the minute I enter their URL, RTC needed if it helps solving the problem
 An entire industry (us!) mapped in a service feature
 Known networks use known methods, unknown connections will not connect from the address book
 Searching for business  Results in Google  Connect right from within the browser
 Mobile entry point for “longer customer relation” is an app  Soon to have inbuilt communication
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 12

13. THE DILEMMA
 P2P communicating using stand-alone tools (integrated + apps) is most likely not going to evolve
 Universal lowest common denominator service is here (telephony, SMS), not yet another one needed
 Stand-alone app “market” saturated
 Best ways for reaching existing known contacts established
 Services today are defined by the front-end design/experience, the back-end technology is irrelevant for users
 Joyn is built by technologists, mainly due to belief in IMS for everything and need to standardize everything
 Does not mean defined NNI or operator bits and pieces not useful at all, but could be achieved better
 How? There are two options
 Give up (do nothing or think Joyn is enough for the next years)
 Look forward (and make finally use of state of the art web technologies)

14. USE YOUR PLATFORM
 If you deployed Joyn hopefully you did not just build a complex system, but also a bucket full of interesting APIs
 SIP ISC interface is no API! We are talking HTTP REST + JSON!
 Jibe brings many APIs out of the box, access to all the capabilities
 Joyn by Jibe on iOS makes already use of these APIs  certain assurance for us that it will not be forgotten
 Benefits
 Integrate capabilities elsewhere and focus on the new capabilities as enabler to build new services
 Does not mean integrate RCS as a service itself, but rather some capabilities into web services to enhance those
 Justification of new investments, use them as enabler to get new capabilities to integrate anywhere
 Important footnote
 I do not mean to buy an RCS platform for this purpose, rather utilizing enabler features that you get anyways
 Web services do not need Telco back-ends most of the time and may often be solved better
 If you have them though there is no need to ignore and neglect them
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 14

15. WE ARE DOGFOODING!
 Not just talking API, but use it right away: Work on a use case and traverse it into reality within a couple of days
(yes, literally!)
 Use case development: Sample marketing campaign by using Joyn as video distribution platform
 Celebrity records videos that are distributed to fans using Joyn
 Reaching (optimistically) thousands of end points can’t shouldn’t be done manually
 Using the Jibe platform API we were able to fully automate the process
 Ridiculously fast: 1 month operating platform, 2-3 days implementation and it works!
 Ingredients to our first (of many) use cases
 Jibe platform API, internal SFTP for current subscribers list, content
 Node.js SDK, several additional packages, all open-source
 This use case is being elaborated and was a motivation for many of us to think beyond “the service”

16. TAKE-AWAYS
THE WEBIFICATION OF COMMUNICATION
 If you do Joyn, have the right approach and get the right partner
 Do not just blindly integrate to the IMS, do not only evaluate your AS for SIP ISC, but more importantly
northbound integration capabilities using REST/JSON
 Standardization aspect of add. capabilities irrelevant, simple REST API (maybe with SDK) more important
 “Proprietary” per Telco definition ≠ Not usable by others (REST + doc/SDK completely fine for web developers)
 Understand and acknowledge the tremendous change to our core business and its paradigms – “think web”
 Standardized core technologies (HTML/CSS/JS, Objective-C, Java), but not services
 Standardized interfaces (REST API w/ doc/SDK is enough) trumps complex E2E scenarios
 Ownership of the screen has a huge impact of how service experience is created
 It is imperative that any new service is considered both from technology and service evolution perspectives
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 16

17. SUMMARY
 Honest thoughts that should have overall positive notion, despite certain critical annotations!
 I am still not too optimistic for Joyn, but can see some potential for Joyn 
 I think your help is needed…
 … also in your interest
 Web technologies leave carrier approaches towards services behind
 Fit-for-purpose applications create real value, every operator needs new revenues
 Empty promises must not convince any longer, eventually they are going to be questioned!
 Creating values beyond the service Joyn is something you want to do, too! Expose your platforms, incl. Joyn
Sebastian Schumann: “Deployment options with hosted RCS”, 7th annual Rich Communication October 2014, Berlin, Germany 17
service platform (get a good partner)
vendors, operators, GSMA, executives, colleagues
Less ubiquitous, but more targeted applications will replace
general purpose legacy-concept communications use case by use case!
