Draft BEREC Guidelines detailing Quality of Service Parameters

BEREC Public Consultation on draft BEREC Guidelines Detailing Quality of Service Parameters

Starting: 08 Oct Ending

17 days left (ends 05 Dec)

Go to discussion and give your opinion.


During its 40th plenary meeting (3-4 October 2019, Crete) the Board of Regulators approved the draft BEREC Guidelines Detailing Quality of Service Parameters for public consultation.

In accordance with Article 104 of the European Electronic Communications Code  NRAs shall take utmost account of these Guidelines when specifying quality of service parameters to be measured, the applicable measurement methods and the content, form and manner of the information to be published.  By 21 June 2020 BEREC shall adopt the above mentioned Guidelines.

The public consultation is open from Thursday, 10 October 2019 , 14:00 to Thursday, 5 December 2019, 17:00 CET.

Please go to the Discussion and give your opinion.

The consultation document is available for download - please see below.

Any techniques used for conducting measurements should be made transparent and available for third-party verification and, if feasible, to end-users at no additional cost, including end-users with disabilities. Recommended approaches within these standards to guarantee accuracy of measurement should also be taken into consideration.


IAS and ICS providers should assess all factors that may impact the QoS levels available to end-users, for example, user environment or the bias brought by the location of test servers or interconnection issues, etc. Whenever possible, providers should take into consideration those factors during the measurement process.

3. Internet access service (network performance QoS parameters)


Article 104 contains a specific reference to Regulation (EU) 2015/2120: “the measures to ensure quality of service shall comply with Regulation (EU) 2015/2120[18]. As a consequence, a close interdependency between the Open Internet and End-Users Working Groups has been acknowledged and, in order to ensure the consistency of BEREC’s documents, the Guidelines do not focus on defining IAS QoS parameters related to the network performance and measurement methods that are analysed within the OI BEREC WG and, in that context, make an explicit reference to several relevant BEREC reports. Therefore, this section only summarises some aspects relative to those QoS parameters. NRAs who require Providers to publish QoS indicators related to the network performance and measurements for IAS should take utmost account of the provisions developed by BEREC OI WG together with the indicators set out in Article 104 EECC Annex X, i.e. latency, jitter and packet loss as defined with measurement methods in ITU-T Y.2617 where applicable.


Annex X of the EECC contains some basic QoS parameters and measurement methods for IAS. Concerning network performance, besides speed, the most important parameters, which influence QoS of IAS, are delay, delay variation (jitter) and packet loss, see BEREC Guidelines Net Neutrality 2016[19], paragraph 137.


BEREC OI WG has also defined network performance indicators to assess the quality of IAS. The experience of this group resulted in various documents. A guidance on how to measure these parameters is given in the BEREC Net Neutrality Regulatory Assessment Methodology BoR (17) 178. These include QoS parameter of IAS, especially:


  • IAS speed in both downlink and uplink direction;


  • Round-trip delay;


  • Delay variation and


  • Packet loss.


A practical implementation of this methodology is currently being developed by the BEREC NN tool, which is based on the BEREC Net Neutrality Tool Specification BoR (17) 179 and the Annex 1 of BoR (18) 32.


In cases where NRAs establish monitoring mechanisms according to Article 4 (4) of Regulation (EU) 2120/2015 these mechanisms shall also be deemed acceptable for monitoring insofar as they provide measurements of the parameters defined by the BEREC OI WG.


According to Figure 1 as set out in para 20 of this document and referenced by the EC in its Final Report “Fixed and Mobile Convergence in Europe”[20] QoS refers to the effectiveness of performance of a system in support of end-user needs or that contributes positively to another system’s performance.


In addition, as set out in Annex 4 to the Guidelines, an extract[21] of the most widely mandated existing QoS indicators across Member States include the following:


  • Voice - Call set-up time; Unsuccessful call rate; Speech transmission quality; Response time for calls to the operator, customer service and directory assistance


  • Mobile - Network availability; Probability of successful connection in an area covered by the network; Dropped call ratio


  • Customer service - Time between request for service and start of service; Fault frequency; Time to troubleshoot & eliminate faults; Frequency of complaints about billing


Depending on the nature of the content to be exchanged (e.g. audio, video, text, data), different quality parameters need to be specified. ETSI EG 202057 multi-part deliverable standards (see Annex X of the EECC) provides guidance on the basic approach to be applied in order to assess the different aspects of quality.
