The present document specifies the stage 3 Protocol and data model for the UAS Application Enabler (UAE) Server services, for enabling the support of Uncrewed Aerial System (UAS) applications over 3GPP networks. It provides stage 3 protocol definitions and message flows, and specifies the API for each service offered by the UAE Server.
The stage 2 application layer architecture for Uncrewed Aerial System (UAS), functional requirements, procedures and information flows necessary for enabling Uncrewed Aerial System (UAS) applications over 3GPP networks are specified in TS 23.255.
The common protocol and interface aspects for API definition are specified in clause 5.2 of TS 29.122.

4 Overview p. 17
The UAS Application Enabler (UAE) Server forms part of the UAS application enabler layer that aims to ensure the efficient use and deployment of UAS over 3GPP systems. The UAE Server supports for this purpose, among other functionalities defined in TS 23.255, the following functionalities:
-
UAS application layer support functions to a UASS (e.g. USS/UTM) over the Us reference point, i.e.:
- C2 operation mode configuration management for a UAS (i.e. pair of UAV and UAV-C);
- C2 communication modes switching control and management for a UAS (i.e. pair of UAV and UAV-C);
- Real-Time UAV Connection Status Monitoring and Location reporting;
- USS change management;
- DAA management;
- UAV dynamic information management;
- real-time UAV flight path monitoring assistance management;
- UAS provided flight routes management; and
- NTZ management;
- interaction with other UAE Servers over the UAE-E reference point, in order to support distributed UAE Server deployments.
