The O-RAN O1 Interface connects the O-RAN SMO to O-RAN managed functions.
It is the main management interface for configuration, fault, performance, accounting, and security management of O-RAN network functions.
Used for
- Configuration management.
- Fault and alarm management.
- Performance management and telemetry collection.
- Software and lifecycle management.
- Security management.
Scope
O1 manages O-RAN functions such as O-CU, O-DU, O-RU, Near-RT RIC, and other managed elements. It is management-plane traffic, not user-plane radio traffic.
