**4.1.1 Communication prioritization**

The objective is to prioritize train-to-earth communications based on several criteria so that the transmission of critical information have more priority over other information that need less "immediacy" when being transmitted.

Therefore, this platform proposes a set of communication requests prioritization criteria in order to respond final applications communication demand (both on ground and onboard train). So, these criteria are applied to establish the order of the communication requests in train-to-earth communication prioritization queues.
