Method and system for providing transparent communication

An air traffic control, ATC, system, the communication system comprising:

• at least one radio station which includes a main radio unit and plurality of associated standby radio units;
• and
• a user console in an air traffic control center, the air traffic control center connected via a communication network to the main radio unit of the radio station addressed by a network address of the communication network;
• wherein the main radio unit and its associated standby radio units are configured to be operated in parallel and to exchange operational parameters during operation of said communication system;
• wherein a selection algorithm executed on a processor of the air traffic control center sorts different standby radio units according to a signal quality of their respective radio links and outputs a rank list of the sorted standby radio units via a user interface to a user, for the user to select in advance one of the standby radio units from the displayed list of standby radio units;
• wherein the main radio unit of the at least one radio station is adapted to send regular keep-alive messages at a regular time interval to the associated standby radio units of said radio station;
• wherein the standby radio units of the at least one radio station are adapted to monitor reception of keep-alive messages from the associated main radio unit of said radio station and to detect an operation failure of the main radio unit of said radio station in case of absence of keep-alive messages received at the regular time interval and are adapted to responsively trigger an automatic handover of the used network address from the main radio unit of the radio station to the selected associated standby radio unit of said radio station to maintain an uninterrupted communication between the user console and the respective radio station of said ATC system.
