BARCELONA -- Telefónica Spain will open up its 4G/LTE network to a large group of selected operators and technology partners from more than 15 countries at this year’s Mobile World Congress to facilitate the first multi-operator 4G (LTE) roaming experience offering roaming high-speed data services.

Delegates from operators in UAE, South Korea, Russia, USA, Hong Kong, France, Portugal, Saudi Arabia and Italy, among others – as well as Telefónica in United Kingdom, Germany, Brazil, Mexico and Colombia – are taking part in the trial. One of the most important characteristics of this new technology is that it replicates the same 4G service quality level usually enjoyed in respective countries of origin.

Telefónica´s technical and wholesale teams in Spain have accelerated the deployment of recommendations otherwise still in the final stages of planning by the GSMA/3GPP (in whose standardisation groups Telefónica actively participates) to enable this pilot.

With this latest milestone, Telefónica continues to lead in innovation digital technology, demonstrating it is ready to include roaming high-speed LTE services to its current extensive roaming coverage, which includes over 700 operators worldwide.

Telefonica will use the LTE Diameter Exchange service offered by Telefónica Global Solutions to provide this experience. It is a service model designed in partnership with Aicent and in line with an Over IPX Services policy. It represents the largest generation of LTE traffic routing (Diameter) signalling, enabling customers to outsource LTE Roaming interoperability function while at the same time extending LTE international coverage.

In addition, in order to verify availability and quality, several Telefónica units, both local and international, have worked with Keynote SIGOS, the world leader in fraud detection and automatic end-to-end tests to measure user experience in telecommunication networks and services. Throughout the pilot, Telefónica will use the largest existing infrastructure to trial roaming services. This system provides access to multiple networks in countries around the world, to permanently monitor roaming services and increase customer satisfaction.

Finally, and coinciding with the Congress, additional test probes have been installed at key locations around Barcelona, including the Mobile World Congress venue itself. This enables Telefónica to simulate global traffic across all the locations, before and during the event, in order to guarantee quality of the service to its customers.
