The application architecture for supporting edge applications are specified in TS 23.558. The UAS application layer as specified in clause 5 can be deployed in edge computing environment. Figure A-1 illustrates a UAS application layer deployment in edge computing environments.

Figure A-1 illustrates how the UAS application architecture with EDGEAPP support for edge deployments can be deployed. In a UE, the UAS application specific client(s), UAE client and SEAL clients interact with the Edge Enabler Client (EEC) via EDGE-5 reference point in order to consume edge services. In an Edge Data Network (EDN), the UAS application specific server(s), UAE server and SEAL servers acting as Edge Application Server (EAS), interacts with the Edge Enabler Server (EES) via EDGE-3 reference point. The service provisioning and EAS discovery enable the UAS application layer entities in the UE to communicate with the application layer entities in the EDN. The interactions between the entities and 5GS are not shown for the sake of simplicity.
