Implications


               No more time-based
                telephony charges


           No concept of local call, long-
             distance call or IDD call

“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.”

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?

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?

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?

Open Internet (Unmanaged networks)

     Variable bandwidth                         Little control
     Higher contention ratio (20:1)
     Less control over content

                                                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

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. 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

  • 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
