world telecommunication policy forum what is it
World Telecommunication Policy Forum: What is it?
  • “The purpose of the forum is to provide a venue for creating a shared vision among policy-makers worldwide on the issues arising from the emergence of new telecommunication services and technologies, and to consider any other policy issue in telecommunications which would benefit from a global exchange of views”
  • “Rough consensus” in the form of opinions which are non-prescriptive and non-binding
  • Some 750 senior policy-makers, regulators and industry experts were present, from more than 120 countries and 100 private sector members
ip telephony what are the issues
IP Telephony: What are the issues?
  • Technical:
    • How to define IP Telephony?
    • Is quality of service comparable? Will it improve?
    • How to handle numbering issues?
  • Economic:
    • What price and cost savings can be expected?
    • How quickly will carriers migrate their networks?
    • Isn’t it just a form of bypass of telecom monopolies?
  • Regulatory:
    • Is it voice or is it data?
    • License it? Prohibit it? Restrict it? Liberalise it?
    • Should IP Telephony contribute to Universal Service?
opinion a general implications of ip telephony
Opinion A: General implications of IP Telephony
  • Implications for Member States
    • the deployment of IP-based networks benefits users, industries, and the economy at large, because it fosters technical and market innovation, diversity and economic growth
    • IP … could be viewed as a significant opportunity for all countries to respond to the convergence of information and communication technologies and evolve their networks;
  • Implications for Operators
    • continuing development of the Internet and IP-based networks is a significant medium for communications and commerce;
    • mobile wireless systems are expected to migrate towards an IP-based architecture in order to deliver integrated voice, data and multimedia services, as well as access to the Internet;
  • ITU … is of the view that:
    • IPTelephony applications are best supplied in a market in which consumers have choices among multiple, alternative sources because only then will citizens, businesses and the overall economy reap the benefits of innovation and cost effectiveness
opinion a invites
Opinion A: Invites …
  • Member States and Sector Members to consider the possibility of the introduction and deployment of IP technologies and IP applications, including the exchange of information;
  • All Member States to review their current regulatory frameworks with a view to:
    • encouraging investment, spurring innovation and advancing development;
    • achieving public policy goals in the context of a converged communication services environment;
    • considering the possibility of opening their communication services market with respect to IP Telephony by adopting a competition-oriented approach in order to achieve clearly defined public policy goals, taking into account, among other things, the concept of technology neutrality for fully-substitutable services
opinion b actions to assist member states and sector members
Opinion B: Actions to assist Member States and Sector Members
  • Encourages Member States to share experiences:
    • on approaches towards making any sector specific regulation technology-neutral;
    • the application of domestic competition laws as part of a pro-competitive policy;
    • establishing sustainable bases to generate financing for universal access/service.
  • Invites the ITU to:
    • Carry out and update IP Telephony case studies;
    • Carry out cost studies and assist Members in performing cost-benefit analyses;
    • Help Member States attract investment
  • Invites ITU to carry out regional workshops on:
    • IP-based technologies and network evolution
    • Cost structures, pricing mechanisms, interconnection, numbering, attracting investment, market considerations etc.
opinion c human resources development
Opinion C: Human Resources Development
  • Recognizing that:
    • the transition to an IP environment places new demands on the management and operation of ITU members;
    • the speed with which countries can extend the benefits of telecommunication technologies will depend on their ability to deploy skilled personnel;
  • Invites the ITU:
    • to facilitate the sharing of knowledge and views, by Member States and Sector Members, of global trends in all new technologies, in particular IP applications;
    • to encourage Member States and Sector Members to create integrated human resources transition plans towards IP;
    • to assist Member States and Sector Members in evaluating and identifying new and changing human resources requirements
opinion d essential studies to facilitate introduction of ip telephony
Opinion D: Essential Studies to facilitate introduction of IP Telephony
  • Invites the three ITU sectors to initiate studies to facilitate the introduction of IP Telephony on:
    • compatibility and inter-operability of radio access between IP networks and PSTNs,
    • working definitions of IP telephony and Internet telephony
    • whether, and to what extent, to require compatibility with the existing international telephone service, including developing appropriate performance metrics and QoS
    • Whether, and to what extent, IP Telephony can be part of national PSTNs and whether traffic identification and measurement need to be considered
    • identifying the cost elements of international IP connectivity with respect to the introduction of IP Telephony
  • Invites the ITU-D to establish a group of experts to:
    • Prepare a checklist of Factors to be considered;
    • Advise on the policy impacts in developing countries;
    • Prepare a report to the next World Telecom Development Conference
