ECC Report E.164 Numbering and Over-The-Top (OTT) Services

In recent years various communication and information exchange services known as Over-The-Top services have emerged. The provision of these services may be provided independently of the Internet access service provider.  Some OTT services use E.164 numbers to enable interoperability with classical telecommunication services. The use of numbers with OTT services raises a number of regulatory issues such as granting rights of use of numbers, access to emergency services and number portability. In order to meet national and European regulatory requirements it would appear that some OTT services would need to be treated in the same way as traditional electronic communications services.

The aim of the report is to gain knowledge on the different regulatory practices and to analyse the need, assignment and use of numbering resources by OTT services/apps and the impact of related regulatory obligations.The conclusions of the Report could inform discussions on the forthcoming review of the EU regulatory framework. The Report should take into account the work of BEREC on the classification of OTT services.

ECC Report Increasing transparency regarding the extra-territorial use of numbers for M2M communication within CEPT member states.
In April 2016 the WG NaN adopted the Recommendation 16(02)” Extra-Territorial Use of E.164 Numbers - High level principles of assignment and use”. In 3) and 4) of this Recommendation it is recommended to create more transparency on the extraterritorial use of E.164 numbers. The need for transparency with this type of use remains important in order to ensure regulatory compliance and to respect national sovereignty.

The idea of increased transparency where numbering resources are used extraterritorially for M2M is also recognized in the European Commission’s recent proposals for amending the regulatory framework (the EECC).

It is proposed to start a process of creating more transparency by gathering information 1) on the regulatory situation regarding the ET use of different numbering resources for M2M communication and 2) on the assignment of these resources. Furthermore it could be envisaged to publish this information on a regular basis via the ECO website.

When compared to a system of ”pan-EU authorisation“ as proposed by the Commission, such a list has the advantage that it does not involve difficult legal questions (e.g. legal basis, powers of enforcement, legal remedies), in particular since the registration is voluntary.
One of the targets is to determine a first set of information (a pilot project – MS Excel file containing sample information) that should be collected by CEPT administrations regarding the NRAs/ECS providers/providers of M2M services in their respective countries

ECC Report Best practices on the sub-assignment of E.164 and E.212 numbering resources 

In September 2017, the WG NaN Strategy Task Force suggested that PT FNI could look at studying the sub-assignment of numbers. PT FNI - based on a questionnaire -  came to the conclusion that in  most countries sub-assignment of E.164 (and in some cases E.212) is allowed or an accepted practice. In some countries there are  rules defined in the numbering regulations; in others sub-assignment is not explicitly addressed in the regulations; in a few countries  sub-assignment is explicitly forbidden.

Sub-assignment of numbering resources may be defined as the practice where all, or part, of unassigned E.164 number block is used by another provider on the basis of an agreement with the original assignee. Sub-assignment is different from number portability and the transfer between providers of an assigned number block which is authorised by the NRA. With the sub-assignment practice, the sub-assignee is allowed to provide to its clients the use of numbers received in sub-assignment.

The work-item has as first objective to create a common understanding of the concept of sub-assignment. Based on that the pro’s and cons of sub-assignment will be assessed. Also numbering regulations/good practices containing rights and obligations e.g. to address the identified problems will be developed with special focus on the finding that sub-assignment of numbering resources inevitably leads to a loss of control by the Number Plan Administrator.  Enforceability of the proposed regulations will also a special point of attention.
