Use the above updated layout for further processing

• SON-Handler MS: Receive and process the message.
• RAN-Sim: Generate the message.

Note: To be checked if VES 7.2 spec shall be used (and any impacts due to using it).

VES 7.2 schema

Send 1 alarm for each collision/confusion

• SON-Handler MS: Time/count to wait before triggering OOF to be fine-tuned
• RAN-Sim: Generate separate alarm onset messages. Alarm messages also have to be stored in DB and used when sending alarm-clear notification.

Send 1 alarm clear message for each collision/confusion getting cleared (eventSeverity: NORMAL)

• SON-Handler MS: Clean up local DB only upon receipt of alarm cleared notification
• SON-Handler MS: We have to maintain an interim state wherein alarm was received and handled (but alarm-clear is not yet received) to differentiate it from alarm-received and not handled case. Enhancement: There should be a timeout for this interim state, which should correspond to the timeout for (n)ack from Policy for the CL. Upon expiry of the timer, it should be moved to "alarm-received and not handled state".
• RAN-Sim: Send alarm clear message upon receipt of config update from ONAP, after verifying that the problem is resolved. Clear the local DB entry.
