    Two different national operators jointly establish an international circuit and decide the revenue they wish to obtain. They then divide that revenue fifty-fifty split.

    • Operator in A is a partner of operator in C

    • Settlement rates A/B > C/B

    Itu t sg 3 major achievements

    ITU–T SG-3 Major achievements

    • New Remuneration system

      • Termination charge system

      • Settlement rate system

      • Special arrangement

    • Difficulty to quickly implement those systems

      • Condition is to reach cost-oriented rate, but

      • No cost data or model for some administrations Group 3 is developing cost methodologies

    • SG3 is now developing cost methodologies

    • Transitional arrangements

      • To facilitate staged reduction to cost based rate

      • to avoid sudden fall of revenue (smooth transition)

    Annex e recommends also

    Annex E Recommends also

    • That transit Administrations move towards the indicative target rate (upper limit) of 0.05SDR (0.07US $) per minute.

    • To negotiate asymmetrical accounting rate (other than 50/50) if both administrations agree to move to below the indicative target rate. Example: Operator A belong to teledensity band EOperator B belong to teledensity band FA and B agree to achieve TAR 0.2SDR (<0.118x2)

      • A can request settlement rate of 0.09 SDR

      • B accepts to pay 0.11SDR to A


    Termination charge

    Termination charge

    • Destination operator (or Government) set the charge

    • Charge should be established based on costs

    • Termaination Charge includes

      • International exchange

      • National extension, including local loop

      • And if appropriate, international circuit

      • Other costs imposed on carriers by the national regulation

    • Those components should be separately identified (Unbundled)

    • Charge applies to all traffic from any source

    • However if significant variation in costs, charge may vary (volume discount)

    • Termination charge may be introduced on bilateral agreement basis

    Accounting rates and Termination Charges

    What’ s the difference


    International call terminating on mobile network

    International call terminating on mobile network

    • SG3 revised D.93 in year 2000, allowing to negotiate

      • a separate rate for traffic terminating on a mobile network

      • however, this is by bilateral negotiation and when the rate is cost orientated

      • The difference between the two rates should be as small as possible

    • Many countries now request very high settlement rates (3 – 5 times)

      • A review is now going on in the SG3

    Internet interconnection

    Internet Interconnection

    • Internet Interconnection has slightly different meaning. Historically Internet interconnection has involved simply different Internet networks.

    • This Internet Interconnection policies have proved increasingly inappropriate in a commercial industry.

      • Many operator with larger networks often charge smaller ISPs a traffic-based interconnection fee

      • Many backbone providers have begun offering transit service networks.

    • Different type of Interconnection Arrangements

      • ISP Relationships with customers: usually via a dial-up

      • ISP-ISP Interconnection: peering or bilateral agreement

      • Multiple ISP Exchanges when several ISPs need to interconnect in a same city (use of an IXP)

    • International Regulatory Development


    Recommendation d 50

    Recommendation D.50

    The ITU-T,

    recognizing

    the sovereign right of each State to regulate its telecommunication, 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.

    IP-Telephony

    Telephone to telephone (fax to fax) via Internet

    Internet

    Phone Gateway Computer

    Phone Gateway Computer

    Telephone

    Public Switch

    Telephone

    • Any telephone/mobile user to any other

    • Main motivation: Accounting rate bypass, market entry for non-facilities-based carriers

    • Potential service providers include any PTO with settlement payments deficit (e.g., US = US$5.7bn)

    • Market potential: 1.3 billion telephone/mobile users


    Ip telephony opportunities and challenges

    IP TelephonyOpportunities and challenges

    • Opportunities

      • Reduce prices to consumers and the costs of market entry for operators

      • In terms of volume of traffic carried and level of investment committed

    • Challenges

      • Undermine the pricing structure of the incumbent Public Telecommunication Operators (PTOs)

      • Transition to IP-based networks also poses significant human ressource development challenges


    Challenges

    Challenges

    Revenue gain and revenue loss

    Conclusion

    Conclusion

    • Transitional arrangements

      • Negotiate in using Annex F, especially for asymmetric arrangements

      • How to move to the termination charge

    • Call terminating on mobile network

      • RPP against CPP
