Norway, Sweden Test First Live TETRA Connection Across Borders
Friday, August 12, 2016 | Comments
The first live test connection between the TETRA networks in Sweden and Norway was carried out 28 June. The Norwegian-Swedish Inter-System Interface (ISI) project is a joint development initiative between the two countries with the purpose of establishing cross-border communications for public-safety agencies.

The two networks are operated by two different organizations. The Norwegian TETRA network Nødnett is run by the Directorate for Emergency Communications (DNK), and Sweden’s Rakel is maintained by Swedish Civil Contingencies Agency (MSB). Two manufacturers supply the TETRA infrastructure networks in the two countries, Motorola Solutions in Norway and Airbus Defence and Space in Sweden.

Sweden and Norway share a 1,619-kilometer-long border, the longest land border for both nations. As both countries are part of the Schengen, citizens’ movement between the two countries is open, this leads to the need for interworking, driven by the need to manage possible emergencies, major public events, state visits, international crime, terrorism or environmental disasters in the border regions.

The Norwegian-Swedish ISI project was established to ensure that emergency services can communicate using their terminals in both countries. The end point of the project will allow officers to cross the border into the neighboring country (terminal migration) and to communicate with emergency services from another nation, as well as with their own team and home control room.

For the coming weeks, the countries will perform continued testing of all TETRA ISI functionality to ensure the connection is stable. The ISI connection uses the European network Trans European Services for Telematics between Administrations-new generation (TESTA-ng) as the transmission between the ISI gateways. TESTA-ng is a communications platform to exchange electronic data between European and member states’ administrations in a secure, reliable and efficient way. E1 lines will serve as backup and to extend capacity as needed, said Marianne N. Storrøsten, DNK senior advisor.

DNK worked closely with radio terminal suppliers to develop software to support the air interface migration. Airbus Defense and Space, Motorola Solutions and Sepura have tested the new radio terminal software and demonstrated the ability for radios to migrate and to give the user feedback of what network they are registered on. ISI will be part of new software releases coming in the fourth quarter. The control rooms also need software changes to handle foreign users.

MSB and DNK as network owners have worked closely with representatives from Norwegian and Swedish public-safety agency to develop a common fleetmap, guidelines for the use of ISI and training materials.

MSB and DNK are developing bilateral agreements to regulate operational aspects of the interconnection between the networks. The agreements regulate the interconnection technical setup and security, operations and fault handling, governance of ISI, end-user services and cost sharing.

The countries will demonstrate ISI to a wider community in a field exercise between Norwegian and Swedish first responders 16 November. Cross-border communications between Nødnett and Rakel will become a daily end-user service in 2017, Storrøsten said.

Extending the work of Norway and Sweden, the Inter System Interoperability for TETRA-Tetrapol Networks (ISITEP) project provides technical and operational building blocks for ISI operation between different nations.

The experience carried out by Norway and Sweden can become a model for other EU countries and is an integral part of ISITEP. In particular, the Norwegian-Swedish ISI project can be used in ISITEP as background of best practices for methodologies, dealing with work processes, distribution of responsibilities, voice group structures, guidelines and transnational legal agreements.

“As soon as the Norway-Sweden collaborations is successfully finished, we will start working with our neighbor countries,” Storrøsten said. “Virve in Finland have stated publicly that they are ready to start as soon as possible.”

Nødnett was rolled out nationwide in 2015 and has close to 50,000 users distributed in all parts of Norway.

A requirements document complied by DNK and MSB is here.
