The aim of the project DEC112 is to develop a modern, standards-based and barrier-free infrastructure for emergency call services in Austria. The development of basic functions and services was supported by Netidee and the European Union and published as Open Source
Since February 2019 these services are in live operation in Austria and form the basic framework for the DEC112 Deaf Emergency Call.
With the project CELESTE, an initial and collaborative test for providing international and standardized emergency services, has already been completed successfully.
The DEC112 App provides text-based access to control centers (fire department, police, ambulance, mountain rescue, ...) in Austria. Upon activation, the current location is determined, which is used to find the locally responsible control center.
If a data connection is available, first the location and user data are automatically transmitted and then any text message can be transmitted. If no messages follow, the location is automatically sent to the control centre every 20 seconds.
In Austria (and other European countries), emergency calls are assigned to a specific control centre on the basis of the originating number. For example, emergency calls (144) from a district in the federal state of Lower Austria are routed to emergency call 144 Lower Austria. Allocation and delivery are carried out in the Austrian telephone network.
Calls from the mobile network or from the internet are a challenge. In the mobile network, the actual location may be in another federal state or in border regions, even in the neighbouring country, and is very likely to be delivered incorrectly. Calls from the internet can, in general, not be assigned to the original number using this method.
The core components, developed as part of the DEC112 initiative, allow allocation and delivery based on actual location. The principle can be applied to any originating network provided that a location can be determined before the connection is established or is announced by the originating network (e.g. Voice over LTE). Assignment and delivery services and their interfaces are specified in TS 103 479
New technology requires appropriate integration with control center systems.
The main advantage of a standards-based infrastructure is the universally applicable interface. Basically, TS 103 479 and TS 103 698 allow multimedia communication (audio, video and data) in addition to simple text messages.
DEC112 offers different methods of control centre connection, starting with a simple, browser-based user interface or via TS 103 479 control center interface.
The project DEC112 would not be possible without the support of our partners Notruf Niederösterreich and the Ministry of the Interior, who handle all DEC112 emergency calls in Austria. Thus establishing adequate emergency services for deaf and hearing impaired people in Austria.
DEC112 has received funding from Netidee in 2017 (Call #12) and 2019 (Call #14) as well as from European Union’s Horizon 2020 Research and Innovation Programme under THE NGI TRUST Grant Agreement No. 825618.
