This part of IEC 61375 establishes the specification for the communication between the on-board subsystems and the ground subsystems.
The communication system, interfaces and protocols are specified as a mobile communication function, using any available wireless technology.
This document provides requirements in order to:
a) select the wireless network on the basis of QoS parameters requested by the application;
b) allow TCMS and/or OMTS applications, installed on-board and communicating on the on board communication network, to have a remote access to applications running on ground installations;
c) allow applications running on ground installations to have a remote access to the TCMS and/or OMTS applications installed on-board.
This document specifies further requirements which allow the applications running on-board and the applications running on ground to connect each other applying the virtual/functional addressing mechanism specified by IEC 61375-2-3 and exchanging application data sets produced or consumed by the on-board functions implemented in the devices attached to the TCN network.
Furthermore, this document covers the security requirements in order to grant the access only to authenticated and authorised applications and to allow encryption of exchanged data.
Note 1: This part specifies the application agnostic communication protocols.
Note 2: With respect to cybersecurity this standard specifies usage of some protocols to ensure interoperability. Further cybersecurity requirements are addressed by standards addressing them (e.g., IEC 62443 and CLC/TS 50701).
Note 3: This part defines communication protocols for non-safety-related applications. It is up to the user to employ suitable higher-layer safety protocols should the communication channel be used for such applications.
Note 4: This part solely defines the interface between the MCG and GCG, their respective northbound interfaces are out of scope of this part.
