Digital platforms and gatekeepers

Many services developed in recent years are based on Internet technologies. Of these web based services, many offer the same or similar functionalities as services previously provided by telecommunications providers and are called Over-The-Top (OTT) services. An excellent example of OTT communications services are instant messaging services. Similar to the traditional SMS or phone call, instant messengers allow users to contact others who have installed the instant messenging service; yet unlike SMS or phone calls, these services only require an Internet connection and do not necessarily require a SIM card to transmit communications. OTT services are often organised as platforms or form a part of large digital ecosystems. Essential services such as browsers, search engines, app stores, operating systems and communications platforms often obtain a gatekeeper position, e.g. in relation to users or third-party providers, and provided they command the necessary market power, they are able to restrict access to the open Internet and its innovation ecosystem. The Digital Markets Act (DMA) also refers to these services as core platform services. 

Cloud services are also defined as core platform services in the DMA. They are offered by telecommunication providers as well as large platforms like Amazon, Microsoft and Google. Cloud services enable companies and consumers to access the necessary, scalable computing capacities across different networks. By using different services from the same provider, users can realise synergies and innovative solutions, but at the same time, closed digital ecosystems can also make it difficult to switch services and limit the interoperability of services from different providers (e.g. when using several cloud services – "multi-cloud"). The Data Act provides for new obligations in this area, which are relevant to large platforms as well as telecommunication providers offering cloud services.

In the provision of platform services, access to high quality data from multiple sources can generate an important competitive advantage over rivals or enable new services and markets. Artificial intelligence (AI) often plays an important role in processing and analysing this data and creating new data and services. The Artificial Intelligence Act addresses the use of these technologies. The Service Desk for Artificial Intelligence set up at RTR serves as a point of contact and information hub for the general public on the topic of AI. A study commissioned by RTR on the use of AI in the Austrian telecommunications sector showed that the sector is at the forefront of digitalisation and the use of data science. Telecommunications operators have established data warehouses and a lot of data from network operations – an important basis for using advanced AI effectively.

TKK, RTR.Telekom.Post and other national regulatory authorities are tasked with ensuring sustainable competition between electronic communications services. In order to fulfil this task, a continuous monitoring of markets for electronic communications services is essential to determine whether and which regulatory intervention is necessary. The European Electronic Communications Code (EECC), and the Austrian Telecommunications Act 2021, aims to promote the interoperability of these services and the development and use of very high capacity networks as well as the provision of innovative and affordable services through variety of services and competition. OTTs and platforms have considerable influence on markets for electronic communications services. For example, in the case of number-independent communications services (such as most instant messengers), the regulatory authority may stipulate interoperability under certain conditions in consultation with the European Commission and other authorities (as is the case with voice telephony services). The DMA entails interoperability obligations on number-independent interpersonal communication services of gatekeepers in basic features. The European Commission can consult BEREC regarding these obligations.

An essential part of the regulatory work on platforms and gatekeepers is therefore also the international cooperation in BEREC and other bodies. BEREC is one of the six European networks or bodies that make up the High Level Group of the DMA. It advises and supports the European Commission in the enforcement of the DMA. The Executive Director of RTR's Telecommunications and Postal Division, Klaus M. Steinmaurer, is currently one of the six members delegated by BEREC to the High Level Group.

TKK and RTR.Telekom.Post are furthermore entrusted with the implementation of the net neutrality rules in Austria and safeguard the function of the Internet as a driver of innovation by overseeing the commercial and technical conditions (design) of the networks.

Studies and projects by RTR

Consultation of the European Commission on the first evaluation of the Digital Markets Act

In July 2025, the European Commission requested feedback on the evaluation of the DMA. The feedback should assess whether the objectives of the regulation, namely to ensure contestable and fair markets, had been achieved and whether obligations under the DMA needed to be adapted. The Body of European Regulators for Electronic Communications (BEREC) responded to this request, and RTR.Telekom.Post actively contributed to the process. The response by BEREC focuses on recommendations on number-independent interpersonal communication services, cloud services and AI in the context of the DMA.

Current Use of AI in the Austrian Telecommunications Sector

The telecommunications sector is a forerunner in digitalisation and data science and therefore offers a good basis for the use of advanced AI. The study published in September 2024 and commissioned by RTR shows the areas in which Austrian telecom operators are already using or planning to use AI, for example in customer management, customer service and network operation. It also highlights challenges and the role of regulation and standardisation.

More than just Text Messages: The Numerous Functionalities of Messengers

In June and July 2024, RTR.Telekom.Post analysed 50 functionalities of popular messengers like WhatsApp, Signal and Telegram. The information obtained allows a comparison of providers and contributes to the discussion on implementing interoperability obligations for messengers in the Digital Markets Act (DMA).

Consultation of the European Commission on "Competition in virtual worlds and generative AI"

In its consultation on "Competition in virtual worlds and generative AI", the European Commission asked for input on experiences and assessments in early 2024. Both the Body of European Regulators for Electronic Communications (BEREC) and RTR.Telekom.Post have responded to this request and have each submitted a statement to the European Commission. These are available for download below.

Usage of communication services on the internet

The report on the usage of communication services on the Internet presents data on the use of Internet telephony, video telephony, video conferencing, messenger and e-mail services in Austria. It is based on a representative survey which collected extensive data on the use of these services as well as SMS and traditional telephony in 2022.

Switching barriers for key Internet services

The report on barriers to switching key Internet services uses a survey of Austrian users to examine switching behavior with regard to mobile phone tariff providers, as well as messengers, browsers and search engines on mobile phones. A representative survey was conducted in 2021 to determine the most important selection criteria for choosing a service, reasons for and against switching, and barriers to switching to an alternative provider.

Single sign on services: Overview and recent developments

In the study published in 2021 Single sign on services: Overview and recent developments, RTR.Telekom.Post examines the markets on which single-sign-on services (e.g. "Sign in with Apple") operate in Austria and Europe, as well as legal and technical changes that might affect them in the future.

Monitoring of interpersonal communication services with a focus on Instant Messaging

In the study Monitoring of interpersonal communication services with a focus on Instant Messaging, RTR.Telekom.Post examines in 2020 the usage of these services in Austria based on empirical data, their embedment into larger digital ecosystems and offers an initial assessment of competition. This study was written in cooperation with the Federal Competition Authority and is available in German. 

Monitoring of digital communications platforms and gatekeepers of the open Internet

The methodological document Monitoring of digital communications platforms and gatekeepers of the open Internet - written 2020 in cooperation with the Federal Competition Authority - provides a basis for enquiries and evaluations of competition issues related to communications platforms. The Executive Summary is available in English. This approach aims to provide a structured methodology for describing relevant competitive dimensions and a basis for future competition analyses, in turn facilitating a preliminary assessment with regard to essential aspects and possible adverse economic effects. This methodological document was revised at the beginning of 2022 with findings from the application. The legal regulations in the Cartel Act and in the political agreement on the European Digital Markets Act (DMA) were taken into account.

The Open Internet: OS, Apps and App Stores

In the course of the study The Open Internet: OS, Apps and App Stores, published 2019, RTR.Telekom.Post took an in-depth look at competition issues in connection with these digital ecosystems based on a representative survey of the use of mobile digital services and interviews with app developers about potential restrictions in app stores. The Executive Summary is available in English.
