Naf Interface
AF Service-Based Interface
RESTful service interface exposed by Application Functions for application-driven network interaction.
Technical Explanation
Exposed by internal or external Application Functions (AF), Naf services allow 5GC network functions to deliver asynchronous event notifications (such as QoS modification alerts or user plane status) directly to enterprise applications.
Key Functions
- Exposes application endpoints to receive asynchronous 5GC notifications
- Facilitates bidirectional interaction between enterprise apps and 5GC
- Supports real-time telemetry integration with edge services
