The xApp A1 mediator exposed a generic REST API by which xApps can receive and sent northbound messages, e.g., for receiving policy intents (e.g., “isolate UEs from cell 5”), for receiving machine learning models, or for sending current application state like a neighbor cell relations table learned from the RAN. The A1 mediator will take the payload from such generic REST messages, validate them, and then communicate the payload to the xApp via RMR messaging.
