1 Scope p. 6
The present document specifies the stage 3 protocol and data model for the Policy Control Event Exposure Service of the 5G System. It provides stage 3 protocol definitions, message flows and specifies the API for the Npcf Event Exposure service.
The 5G System stage 2 architecture and the procedures are specified in TS 23.501, TS 23.502 and TS 23.503.
The 5G System stage 3 call flows are provided in TS 29.513.
The Technical Realization of the Service Based Architecture and the Principles and Guidelines for Services Definition are specified in TS 29.500 and TS 29.501.
The Policy Control Event Exposure Service is provided by the Policy Control Function (PCF). This service exposes policy control events observed at the PCF.
