2. 2 ETNS ETNS Interconnect Tariff Models Revenue neutral local Revenue neutral national Revenue share local Revenue share national Incoming from non-ETNS country Note :Retail and interconnection tariff models are still under discussion within the ETNS Steering Committee and the ETNS Interconnect Working Group. Constructive input welcome

3. 3 ETNS ETNS Revenue Neutral Local Calling party pays local tariff ETNS customer not charged an additional per call fee May be popular where majority of calls terminate close to calling party & are not switched beyond originating operator’s network Possible services : –Franchised taxi service same +3883 number for many European cities –Fast food home delivery Large penetration in many European countries, Eg. Pizza Hut Service provider may not charge per call fee to network operator’s - receive income from service provided, Eg. taxi service as Service Provider

4. 4 ETNS ETNS Revenue Neutral National Calling party pays national tariff ETNS customer not charged an additional per call fee May be popular where majority of calls terminate within the same country as the calling party & are not switched beyond originating operator’s network Possible services : –Travel industry Hotel chain front desks, airlines, franchised travel agents operating many offices in several countries –Banking industry Operations in several countries but offices in each country –Roadside assistance Alliances between different organisations in many European countries

5. 5 ETNS ETNS Revenue Share Local Calling party pays local tariff ETNS customer pays per call fee to Service Provider May be popular where majority of calls cross international boundaries Service Provider pays Serving Network or reverse depending on which operator carries call the greatest distance Possible services : –Companies offering services in several countries but without offices in each country. –Could be used for marketing purposes where ETNS customer wishes calling party to pay small amount for call & ETNS customer pays higher percentage of total call cost

6. 6 ETNS ETNS Revenue Share National Calling party pays national tariff ETNS customer pays per call fee to Service Provider May be popular where majority of calls cross international boundaries Service Provider pays Serving Network or reverse depending on which operator carries call the greatest distance Possible services : –Companies offering services in several countries but without offices in each country –Could be used for customer service purposes where ETNS customer wishes calling party to pay larger share of call cost

8. 8 ETNS Incoming from Non-ETNS Country Calling party charged an international rate similar to the rate charged within originating country for a call to a geographic number in an average European country. One rate applied to calling party regardless of retail tariff arrangements within ETNS area. Operators within the ETNS zone are free to offer international call termination rates to ETNS numbers. ETNS customers able to decide whether they will accept calls originated from outside ETNS area.

10. 10 ETNS Market Introduction of European Numbers Publicise European numbers –By telecommunications industry First, to internal participants Next, to general public –By ETNS customers Use European numbers for everyday services Develop trust in European numbers –Simple tariffs, easy to understand –European number  an expensive call Allow the market to determine future

11. 11 ETNS Changes in Perception For operators, 00  international –ETNS calls not routed as international calls –003883 passed between operators at national interconnect level For customers, 003883  international –003883 tariffs are not international tariffs

12. 12 ETNS Serving to Service Network Relationship Serving Network Responsibility: Route ETNS calls to the Service Network that currently switches a particular ETNS customer’s traffic to its destination. Serving Network to Service Network Relationship: Passing calls between Serving Networks & Service Networks is likely to produce the most friction between ETNS players because: The choice of Serving Network is under the control of the originating operator. The choice of the Service Network is under the control of the Service Provider. Serving Networks are forced to develop relationships with all Service Networks.

13. 13 ETNS Serving to Service Network Relationship - 2 Service Network POP could be: In same city as calling party In another part of the same country as calling party In a different country to the calling party Payments between Serving and Service Network for call carriage between the networks should reflect the distance the call is carried. Serving Network operators have no control over Service Network POP locations, but have a responsibility to deliver calls to these locations. Some Service Networks could have significantly more POPs than some Serving Networks, ie. a Service Network POP may be available in same city as calling party but Serving Network POP is located in another part of country. Interconnect tariff arrangements between Serving & Service Networks must attempt to balance these issues.

14. 14 ETNS Possible Service Network Scenarios One POP in one country offering services in many countries - Many calls between Serving & Service Networks will be across international boundaries One POP in each country in which services are offered - The distance between Serving & Service Networks will be long for many calls Distributed network of POPs in some countries in which services are offered -In some countries, the distance between Serving & Service Networks will be long for many calls -In other countries, there will be a short distance between Serving & Service Networks Distributed network of POPs in each country in which services are offered -The distance between Serving & Service Networks could be short for most calls

15. 15 ETNS Serving to Service Network Tariff Issues Serving & Service Network operators will wish to minimise for call handling costs as much as possible. For some tariff models, all call revenue will be received by the Assisting/Serving Network from the calling party. Money will need to be passed forward along the chain of players involved. For other models, some revenue will be received from the calling party by the Assisting/Serving Network while other revenue will be received by the Service Provider from the ETNS customer. Money may flow in either direction depending on factors such as: –The relative amounts paid by the calling party and the ETNS customer. –The distance the call is carried between the Serving & Service Networks.

16. 16 ETNS Serving to Service Network Tariff Issues - 2 For some tariff options, Serving Network will pay Service Network. The amount paid to the Service Network should decrease as the distance between the Serving & Service Networks increases. For some tariff options, Service Network will pay Serving Network. The amount paid to the Serving Network should increase as the distance between the Serving & Service Networks increases. For some tariff options, the Serving Network will pay the Service Network where the distance between the two operators is small while the Service Network will pay the Serving Network where the distance is large.
