message category is defined by ICAO and mapped to the supported ATN mobile subnetworks in table 3-3 of Annex 10 Vol III. Considering the ATS and AOC classes of service as defined in the previous sections, the following table provides a mapping of the AeroMACS services to the ATN network layer priority levels.
