This project is done for the final project of the internship from Jun. to Nov. in LITEON Networking 5G Team.

Take away

The designed rApp(CCMO; Cell Coverage Monitoring and Optimization) and xApp(CPO; Cell Performance Optimization) would work collaboratively for the automatic continuous monitoring of the field coverage.

Summary

On the topic of automatic continuous monitoring, we proposed a collaboratively working rApp and xApp to achieve it. In the CCMO; Cell Coverage Monitoring and Optimization rApp, it would subscribe to the computation result from the CCO; Coverage and Capacity Optimization periodically to acquire the information used for CCMO.
If CCMO application is ENABLED in the field, it would generate the policy periodically and send it to A1 Mediator in Near-RT RIC Framework, which can be sent to the CPO xApp eventually.
When CPO; Cell Performance Optimization gets the policy request, it would check if there is a relative CONTROL message and then trigger the modification for the parameter in the subscribed devices(All-in-one Small Cell).

Note

• The architecture of the automatic continuous monitoring project
  

• The applications can be done in several ways; in the aforementioned texts, we implemented it through A1-P to the xApp. We can achieve it through A1-EI as well; CCMO acquires the necessary information from CCO periodically, then CPO subscribes the result in CCMO in routine to get the latest parameter to set to the parameters.

• If we need a light-weight RIC architecture, the application can also done in a single Non-RT RIC architecture. By subscribing the result from CCO to CCMO in routine, CCMO can apply the latest result through O1 interface to the devices in the field.
