Question: In a 5G System with Service Based Architecture, how does an NF (Network Function) indicate support for the OLC-H (Optimized Load Control - High Priority) feature to the NRF (NF Repository Function)?
Option 1: Through a dedicated OLC-H signaling message sent periodically to the NRF.
Option 2: By including a specific OLC-H feature support indicator in NFRegister or NFUpdate requests to the NRF.
Option 3: Only when an NF Service Consumer queries the NRF using NFDiscover, and then the NRF prompts the NF for OLC-H support.
Option 4: Via a separate configuration file uploaded to the NRF during NF onboarding.
Explanation: In the context of 5G's Service Based Architecture, Network Functions (NFs) communicate their capabilities and features to the NF Repository Function (NRF) during registration or updates. Specifically, for the OLC-H feature, an NF signals its support by including a relevant indicator in the NFRegister or NFUpdate requests. This approach ensures the NRF has up-to-date information on which NFs support OLC-H, facilitating informed service discovery and provisioning for NF Service Consumers.
