Siemens Mobility Selects Softil MCPTT Technology for LTE-R Solution
Tuesday, August 06, 2019 | Comments

Siemens Mobility and Softil announced an agreement to bring a range of next-generation communications solutions to market for use in Long Term Evolution-Railway (LTE-R) railways as well as mission-critical push-to-talk (MCPTT) metro applications such as underground, trams and buses.

The mission-critical to everything (MCX) solutions will support the Future Railway Mobile Communications Systems (FRMCS) of the International Union of Railways (UIC) to build a Global Rail Traffic Management System (GRTMS) for the rail industry, bringing significant economic and operational benefits and efficiencies to operators in the process.

“The rail industry is at the forefront of the mission-critical communication revolution and GSM-R based systems have already been replaced by LTE-R solutions in Asia Pacific, and the trend is expected to widen across other markets in 2019 to 2020,” said Pierre Hagendorf, Softil’s CEO. “With Softil’s BEEHD client framework at the heart of Siemens Mobility’s next-generation LTE-R offerings, the rail industry will have a range of supremely reliable solutions packed with rich communication features.”

The new radio system for the railway industry has to guarantee the interoperability with GSM-R while delivering in three main areas.

Critical communications must provide secure voice communications between the driver and signaller, provision for emergency and group calls, real-time video imagery for any occurring incidents and the intelligent bearer for European train control system (ETCS) and automatic train operation (ATO). Performance communications should track condition monitoring, connected driver advisory system (C-DAS), on-train telemetry, maintenance of noncritical infrastructure, noncritical real-time video and wireless communications for on-train staff. Business communications provide passenger information system, entertainment and communications connections.

Siemens Mobility will enable existing GSM-R users to develop a migration plan that will enable all three of the areas, a statement said. LTE-R is the foundation for the railway variant of the Third Generation Partnership Project (3GPP) MCPTT standard. LTE-R technology brings the full power of broadband networks beyond voice including voice, video, text, images and location.

The Softil BEEHD framework is LTE-R compatible and will enable Siemens Mobility’s solutions to deliver stable voice and data communications on trains running at speeds in excess of 400 kilometers per hour (kph). LTE-R technology makes possible live tracking of a train and transmitting railroad information to engine drivers, as well as enables multimedia-based group calling and messaging services on top of voice call services. Additionally, real-time group and individual communications is possible between train engineers and control centers.
