If distance is dead, and bandwidth is infinite … What do we bill for? 19

What do we bill for? l Bill for network connection Ø Increasing integration of monthly telephone subscription and Internet subscription prices l Bill for privacy/advertising Ø Privacy-protected customer pays premium Ø Customer agreeing to receive advertising pays less l Bill for quality of service Ø Differentiated by transmission quality, waiting time, bandwidth on demand, value-added secretarial support, mail functions etc. , l Bill for Billing Ø Customising of billing: by service, by user, by site 20

Internet, price and service trends l Towards a flat-rate price structure Ø All you can eat for US$20. 00 l Towards lower service quality Ø “Best efforts” service delivery at lowest price l Death of distance Ø Message to other side of earth costs same as a message sent next door l Cross-promotion of Internet and other services Ø “Free PC” with three year’s ISP subscription Ø “Free Internet” with residential local loop charges l Tendency towards industry concentration Ø AOL’s subscriber base > next ten ISPs added together 21

Challenges for developing countries l Service, tariff and technical issues Ø Alternative calling procedures Ø Public switched network to IP based network Ø Challenges related to mobile service l Regulatory issues Ø Interconnection rules Ø Implementation of USO Ø Tariff Rebalancing l Internet connectivity in developing countries Ø Guideline for negotiating IIC Ø Traffic based negotiation 22

The influence of IP Telephony on price l IDC forecasts that “Web Talk” revenues will reach US$16. 5 bn by 2004 with 135 billion mins of traffic (skype. com, l Gartner Group forecast that IP Telephony and competition in Europe will reduce prices by 75% l Telegeography; in 2002 Vo. IP incresed by 80%, and comprised about 10. 8% of all int’l call traffic (8 trillions mins) l IP Telephony as % of all int’l calls in 2004 “Web Talk” revenues, US$bn Ø Tarifica forecast 40% Ø Analysys forecast 25% l In developing countries, the majority of IP Telephony calls are incoming Source: IDC. 23

Key Interconnection Rules in the WTO Reference Paper Interconnection with “Major Supplies”must be available - At any technical feasible point in the network - In a timely fashion - At cost orientated rates - On non discriminatory and transparent terms - On an unbundled basis - At non-traditional interconnection points if requester pays charges Procedures for interconnection to major suppliers must be made public Transparency Agreements of major suppliers’ model interconnection offers must be made public Dispute resolution An independent entity (which may be the regulator) must be available to resolve interconnection dispute within a reasonable time 28 frame

Regulatory and technical issues l Policy makers must resolve such basic questions as: Ø which carriers are required interconnection Ø How the costs will be calculated and recovered, and Ø At what points in the PSTN interconnection should occur l Regulatory issues Ø Establishing guidelines in Advance (without it, interconnection negotiation are frequently protracted, delaying the introduction of competition) Ø Introducing competition require “dominant carriers” to interconnect with other carriers Ø Cost orientation: excessive prices deter market entry, hinder competition, end user suffer and can provide a pool of revenue l Technical issues Ø Points of interconnection: incumbent operators permit inter- connection with their networks at any technically feasible point Ø Dialling Parity and Pre-selection: Call-by-call customer selection or Operator pre-selection by pre-subscription 29 Ø Quality of Interconnection Service

Economic issues The economic issues involved in interconnection largely come down to question of cost: cost definition, cost measurement, cost allocation and cost recovery l How can interconnection costs be measured? Ø Theoretical Frameworks (Historica, Fully Distributed costs, LRIC) Ø Cost study Approaches (Top-Down, Bottom-Up, Outside-In) l Interconnection charge Ø Ø Ø Cost based charges Retail-based charges Price Caps “Bill and Keep” or “Sender Keeps All” Revenue Sharing 30

Main study items in ITU-T SG 3 l Accounting rate reform Ø Ø Transitional arrangements Action to facilitate negotiations Cost Methodologies Network externalities l Mobile termination charge Ø Differences with fixed network services Ø Level of termination charges l International Internet Connectivity Ø Implementation of Recommendation D. 50 Ø Improving connectivity in LDCs l Other studies Ø International Telecommunication Regulations 31

Solutions & difficulties l New Remuneration system (adopted) Ø Termination charge system Ø Settlement rate system Ø Special arrangement l Difficulty to quickly implement those systems Ø Condition is to reach cost-oriented rate, but Ø No cost data or model for some administrations ⇒ SG 3 developed principles and TAF, TAS, TAL cost models l Transitional arrangements (review at WTSA) Ø To facilitate staged reduction to cost based rate Ø to avoid sudden fall of revenue (smooth transition) l SG 3 developed: Ø Guidelines for negotiation 32

ITU-T Recommendation D. 50 International Internet Connection The World Telecommunication Standardization Assembly (Montreal, 2000), recognizing the sovereign right of each State to regulate its telecommunications, as reflected in the Preamble to the Constitution, noting a) the rapid growth of Internet and Internet protocol-based international services; b) that international Internet connections remain subject to commercial agreements between the parties concerned; and c) that continuing technical and economic developments require ongoing studies in this area, recommends that Administrations involved in the provision of international Internet connections negotiate and agree to bilateral commercial arrangements enabling direct international Internet connections that take into account the possible need for compensation between them for the value of elements such as traffic flow, number of routes, geographical coverage and cost of international transmission amongst others. 37 Greece and the United States of America have expressed reservations and will not apply this Recommendation.

Results of SG 3 meeting (May/June 2004) ①Adoption of Appendix to facilitate implementation of D. 50 ② Self-help by smaller networks with limited traffic ③Continuation of work on Traffic Measurement 38

Network Externality l Universal Service Obligation Fund = Cross Subsidy Ø Not recognized as cost l Network extremity = increase utility of a network to users Ø operators to provide incentives for users to join the network = this can be added to the usage price or to the monthly subscription fee l the network externality effect has a solid basis in economic analysis and had successfully – at least with some regulators – been brought to bear by mobile operators on their case for higher termination rates Ø Can be used by the developing countries to enhancing take-up and roll-out of the network 39

International externalities Country A (Calling) Customers A Access network A 1 Accounting Access network A 2 International operator A rate International operator B Access network B 1 Country B Access network B 2 Customers B Do Customers in A derive benefit from more Customers in B? If so, how much? Is benefit to calling operators in A enough incentive to agree prices above cost? How can we be sure that an externality will be passed through to connect more customers in B? (Called) 40

International Telecommunication Regulations (ITRs) l ITRs elaborated in 1988 Ø Monopoly situation Ø Basic services only (Telephony) l New Market situation Ø Competition Ø New services (Mobile, Internet) l Need for new ITRs? Ø Redraft ITRs Ø Integrate into Constitution and Convention l Study Group 3 starts reviewing ITRs Ø Rapporteur Group on ITR review (tsg 3 itr) 41
