Reaching higher level of autonomy requires self-adaptive automation features within a flexible architecture. Service management based on TM Forum Open APIs, enhanced with intent, is a key component that evolves the established base of network automation into an requirement-driven and self adaptive system. Furthermore, modern network management architectures, such as ORAN SMO provide an open and flexible environment, in which rApps and other functions including orchestration and assurance collaborate to optimize network operation. This project demonstrates the use of TM Forum Open APIs and intent from the business layer, through the service management layer all the way to rApps. This demonstrates how the entire multi-layer network operation stack can reach higher levels of autonomy beyond single use cases.
