Detailed Description
This rApp operates within the Non-RT RIC and SMO, where it uses OAM services to declaratively manage radio spectrum configuration.
- It first retrieves the current network specification through the OAM API to obtain the active cell-level spectrum parameters.
- The rApp then inspects and updates fields such as operating band, frequency, bandwidth, and subcarrier spacing based on operator intent or automation policies.
- After updating the configuration, the rApp submits the modified specification back to the SMO. The underlying OAM workflow propagates the changes to the managed RAN components.
- Finally, the rApp re-validates the configuration to confirm that the new spectrum parameters have been applied successfully. This enables safe and auditable spectrum reconfiguration for tasks such as band refarming, adapting to spectrum availability, optimizing capacity, and testing new radio profiles, without requiring manual per-node updates.
