7.1.1 Generic workflow

28.1003GPPLevels of autonomous networkManagement and orchestrationRelease 17TS

Following is the generic entire workflow for the network optimization:

Intent handling:

– Task A: Network optimization control information generation and determination. The tasks of generating and determining the network optimization related control information (e.g., control information for network issue identification, network issue analysis and network parameters adjustment) based on received network optimization intent (e.g. network targets for the specified areas).

– Task B: Network optimization intent fulfilment evaluation. The tasks of evaluating network optimization intent fulfilment information (e.g. corresponding network targets are satisfied or not).

Awareness:

– Task C: Network related information collection. The tasks of collecting network related data, including network performance data (i.e. performance measurement, MDT data), network configuration data and environment data (e.g. electronic map)).

Analysis:

– Task D: Network issues identification. The tasks of analysing the network performance (e.g. geographical grid based network performance) and identifying whether there are network issues (e.g. coverage related issues, RAN UE throughput related issues).

– Task E: Network deterioration prediction. The tasks of analysing current network performance and historical network performance, predicting the network performance trend in the future and identifying potential network performance deterioration in advance.

– Task F: Network issue demarcation. The tasks of analyse the network issue and determine the network issue categories (e.g. weak coverage, high load, low throughput).

– Task G: Network issue root cause analysis. The tasks of analysing the root cause (i.e. the location for the issue occurs and the cause for the issue) of the identified or predicted network issues.

– Task H: Network adjustment solutions analysis. The tasks of generating the recommended network adjustment solution which can address the identified or predicted network issues.

Decision:

– Task I: Network adjustment solutions evaluation and determination. The tasks of evaluating the recommended network adjustment solutions, and deciding the network adjustment solutions to be executed.

Execution:

– Task J: Network adjustment solutions execution. The tasks of adjusting and configuring the network configuration parameters.
