  12. 12. Change in Business Paradigm Traditional Telecom Model New Telecom Model Value-Added Voice Service Data Service Value-Added Service Voice Service Data Service Infrastructure Infrastructure “The most powerful paradigm shift is the fact that applications are not woven into the platforms. Now to be a phone company, you don't have to weave tightly the voice service into the infrastructure. They (Vonage) turn voice into a application and shoot it across one of these platforms. And, suddenly, you're in your business.” – Michael Powell, Chairman of FCC 1-Nov-09 Nov- IMT MM-Biztel MM- 12
  13. 13. Technical Issues Technical Architecture To achieve interoperability between different IP Telephony services, What should be the technical common platform? What are the technical specifications to adopt? Quality of Service What is the acceptable QoS for IP Telephony? How to ensure QoS? Security and Privacy How secure is IP Telephony? What about wiretapping requirements? 1-Nov-09 Nov- IMT MM-Biztel MM- 13
  14. 14. Business Issues Interconnection Who can interconnect to PSTN? What is the pricing model? Market Studies What is the economic impact? How would it change the telco landscape? (cost to setup IP Telephony service ~= cost to setup Email service) Numberings What’s is the numbering plans for IP Telephony? How are numbers assigned for IP Telephony services? What if there is no service provider? 1-Nov-09 Nov- IMT MM-Biztel MM- 14
  15. 15. Regulatory Issues Classification How do we classify all the different IP Telephony services? Are they subjected to similar “regulation”? Licensing Who needs to apply for license? What if there is no service provider? Universal Access Is it applicable to IP Telephony? How about emergency numbers? 1-Nov-09 Nov- IMT MM-Biztel MM- 15

YouTube, BBC iPlayer on browser/PC Eg. 1-Nov-09 Nov- IMT MM-Biztel MM- 19
  20. 20. Open Internet (Unmanaged networks) Variable bandwidth Little control Higher contention ratio (20:1) Less control over content } over ‘quality of service’ The Content Provider need to working to ensure quality of service with ISPs. This will possibly change the definition of IPTV through the consensus that the quality of service is good over the open internet 1-Nov-09 Nov- IMT MM-Biztel MM- 20
