QoS in the EU Regulatory Framework


QoS in the EU Regulatory Framework


Framework Directive / Access Directive� The national regulatory authorities shall promote competition in the provision of

electronic communications networks, electronic comm unications services and associated facilities and services by inter alia:� (a) ensuring that users, including disabled users, derive maximum benefit in terms of

choice, price, and quality� […]


� […](FD Article 8)

� Where an operator is designated as having significant market power on a specific market as a result of a market analysis […] national regulatory authorities shall impose the obligations set out in Articles 9 to 13 of the Access Directive as appropriate (AD Article 8)

� Obligations of non-discrimination shall ensure, in particular, that the operator applies equivalent conditions in equivalent circumstances to other undertakings providing equivalent services, and provides services and information to others under the same conditions and of the same quality as it provides for its own services, or those of it subsidiaries or partners (AD Article 10)


Universal Service Directive (1)� The aim is to ensure the availability throughout the Community of good quality publicly

available services through effective competition (Article 1)

� National regulatory authorities shall ensure that all designated undertakings […] publishadequate and up-to-date information concerning their performance in the provision of universal service , based on the quality of service parameters, definitions and


universal service , based on the quality of service parameters, definitions and measurement methods set out in Annex III (Article 11)

� National regulatory authorities may specify, inter alia, additional quality of service standards , where relevant parameters have been developed, to assess the performance of undertakings in the provision of services to disabled end-users and disabled consumers (Article 11)

� National regulatory authorities shall be able to set performance targets for those undertakings with universal service obligations […] (Article 11)


Universal Service Directive (2)� Member States shall ensure that national regulatory authorities are […] able to require

undertakings that provide publicly available electronic communications services to publish comparable, adequate and up-to-date information for end-users on the quality of their services (Article 22)

� National regulatory authorities may specify , inter alia, the quality of service parameters to


� National regulatory authorities may specify , inter alia, the quality of service parameters to be measured […]. Where appropriate, the parameters, definitions and measurement methods given in Annex III could be used (Article 22)


Reference Offer / Interoperability of Services� […] where an operator has obligations of non-discrimination, national regulatory authorities

may require that operator to publish a reference offer […] giving a description of the relevant offerings […] and the associated terms and conditions including prices (AD Article 9)

� National regulatory authorities shall […] encourage and where appropriate ensure […]


� National regulatory authorities shall […] encourage and where appropriate ensure […] adequate access and interconnection, and interoperability of services , exercising their responsibility in a way that promotes efficiency, sustainable competition, and gives the maximum benefit to end-users (AD Article 5)


Potential Areas for NGN QoS Standardisation


Potential Areas for NGN QoS Standardisation


Quality of Universal Service (1)� QoS parameters, definitions and measurement methods set out in Annex III of the USD have

to be used



Quality of Universal Service (2)� Member States may decide not to require that up-to-date information concerning the

performance for Unsuccessful call ratio and Call set up time be kept , if evidence is available to show that performance in these two areas is satisfactory

� Version number of ETSI EG 201 769-1 is 1.1.1 (April 2000)


Is ETSI EG 201 769-1 applicable to NGNs?

If not, ETSI EG 201 769-1 should be further developed so that it is also applicable to NGNs.


Quality of Service for End-users� NRAs are empowered to require communications service provider to publish information

for end-users on the quality of their services� NRAs may specify the quality of service parameters to be measured� Maybe some Member States already oblige communications service providers to publish

information on the quality of their services and maybe they also specify the QoS parameters� In Austria, so far there had not been the need to do this. But maybe this need will arise in the

future


future

Are existing QoS standards (e.g. ETSI EG 202 057, ETSI EG 202 009-2) already applicable to NGN?

If not, maybe regulators will need a further development of these standards.

Does QoS standards (defining QoS parameters) for NGN services already exist?

If not, maybe regulators will need such standards.


Reference Interconnection Offer (RIO) (1)� SMP operators are usually required to publish a RIO� The RIO may use QoS parameters� In Austria , in the RIO of the incumbent Telekom Austria the following QoS parameters

are used:� Operational Answer Seizure Ratio (ASR)� Call set-up time


� Call set-up time� Availability of the C7 Route Set� Availability of the joining link� “Netzdurchlasswahrscheinlichkeit” (Ratio of calls successfully put through a network)� Network Effectiveness Ratio � Call Successful Ratio


Reference Interconnection Offer (RIO) (2)� It is likely that SMP operators will migrate their networks to NGN in the future

What QoS parameters will be needed for NGN-NGN, NGN-PSTN and NGN-PLMN interconnection?

Are these QoS parameters already standardised?


If not, such standards maybe needed already in the near future.


Reference Bitstream Offer (RBO) (1)� SMP operators are usually required to publish a RBO� Bitstream is usually used to provide internet access products to end-users� Maybe QoS parameters are used in the RBO� In Austria , in the RBO of the incumbent Telekom Austria the QoS / NP parameter

overbooking factor is used� In Austria , the incumbent Telekom Austria had also the obligation to offer a bitstream


� In Austria , the incumbent Telekom Austria had also the obligation to offer a bitstream product� which enables Other Legal Operators (OLOs) to offer voice telephony services which

can compete with the telephony services offered by Telekom Austria and� which meet the NP objectives for voice telephony services e.g. the NP objectives of

class 1 of ITU-T Rec. Y.1541 and of ITU-T Rec. G.114


Reference Bitstream Offer (RBO) (2)� SMP operators will introduce in their access networks Next Generation Access (FTTC,

FTTB, FTTH)� The introduction of Next Generation Access may lead� to the need of an “enhanced” bitstream product with greater flexibility and� with the possibility to provide on top of it other services than internet access

� It is likely that the “enhanced” bitstream product


� It is likely that the “enhanced” bitstream product � will be an Ethernet service and � that it has to support CoS

QoS / NP parameters for Ethernet services has already been standardised (e.g. MEF 10.1). Is there still a need for a further development of these standards?

Maybe regulators will also need QoS /NP performance objectives depending on the service for the end-user which is provided on top of the Ethernet service

Maybe QoS classes will be useful and QoS performance targets for QoS classes (similar to ITU-T Rec. Y.1542) will be needed.


Reference Leased Line Offer (RLLO)� SMP operators are usually required to publish a RLLO� Usually QoS parameters are used in the RLLO� In Austria , in the RLLO of the incumbent Telekom Austria the QoS parameters maximum

bit error rate (ITU-T Rec. G.821, ITU-T Rec. G.826) and availability are used� SMP operators will migrate their networks to NGN and their transport networks to

Ethernet


Ethernet� QoS /NP parameters for Ethernet service has already been specified

What are the QoS performance objectives for Ethernet leased lines?


Interoperability of Services (1)� QoS is a key feature of NGN� In order to ensure interoperability of services functional interoperability is needed between

the different Layers in a NGN and between different interconnected operatorsService Layer

Interoperability of Services (2)� Standards leave room for different implementations

Are the NGN standards sufficient specified so that it is ensured that different implementations are interoperable with each other?



New Telecom Package


New Telecom Package


New Telecom Package� Review of the Regulatory Framework for electronic communications

networks and services proposes now� Better Regulation Directive

amending framework directive (2002/21/EC), access directive (2002/19/EC) and authorisation directive (2002/20/EC)


� Citizen’s Rights Directiveamending universal service directive (2002/22/EC), privacy directive (2002/58/EC) and regulation (EC) No 2006/2004 on consumer protection cooperation

� Regulation establishing a Body of European Regulators for Electronic Communications and the Office


Status and Timescale� In May 2009 an informal agreement between the Council and the

European Parliament (and also the European Commission) was achieved

� The European Parliament accepted in the second reading in May 2009 this informal agreement, but – unfortunately – with the exception of one


this informal agreement, but – unfortunately – with the exception of one article

� The last chance for an agreement between the Council and the (new) European Parliament (and the European Commission) will be during the third reading in autumn 2009

� In this case, the directives will have to be transposed into national law within 18 months (which means till the middle of 2011)


Quality of Universal Service � QoS parameters, definitions and measurement methods set out in Annex III of the USD

have to be used� No change of the parameters , but the definition and the measurement methods of the

parameters have to be based on ETSI EG 202 057 instead of ETSI EG 201 769-1


Is ETSI EG 202 057 applicable to NGNs?

If not, maybe there will be a need to further develop ETSI EG 202 057 so that it is also applicable to NGNs.


Quality of Service for End-users� In order to prevent the degradation of service and the hindering or slowing down of

traffic over networks, Member States shall ensure that national regulatory authorities are able to set minimum quality of service requirements on an undertaking or undertakings providing public communications networks (USD Article 22)


Maybe regulators will have the need for different NGN services to define based on QoS standards minimum QoS objectives. Are standards for this purpose already available?


Conclusions


Conclusions


Conclusions� QoS is relevant in many different areas of regulation, amongst others � Quality of universal service� Quality of service for end-users� Reference Interconnection Offer� Reference Bitstream Offer


� Reference Leased Line Offer and� Interoperability of services

� There is a move from legacy networks to NGN

Are the standards already used in regulation also applicable for NGNs?If some are not, regulators will need a further development of these standards.

Are the NGN standards sufficient specified so that interoperability between services is ensured?If some are not, from a regulatory point of view a further development of these standards would be desirable.
