1  Scopep. 7

The present document studies on enhancement of autonomous network levels. It introduces the relevant study items and work items in 3GPP, identifies the additional generic MnS requirements of generic autonomous network level for the scenarios defined in Rel-17 and documents potential solutions for the identified generic MnS requirements. It also identifies the enhanced autonomy capabilities corresponding to different autonomous network levels for additional management use cases which is not defined in Rel-17 and documents potential solutions for the enhanced autonomy capabilities. Based on the investigation and studies, it provides recommendations for the further normative work.

4  Introduction on relevant study items and work items in 3GPPp. 8

In TS 28.100, categorizations of the tasks in a workflow are specified in clause 4.3.4 including intent handling, awareness, analysis, decision and execution, and these task categories are used in the framework approach for evaluating autonomous network levels (ANL) in clause 5 of TS 28.100.
In clause 4.2.1 of TS 28.535, management control loop including monitor, analytic, decision, execution is described. And in clause 6.1 of TS 28.104, management loop including observation, analytics, decision, execution is specified as well. The management control loop and management loop defined in TS 28.535 and TS 28.104 are similar, and both of them have the similar consideration with the workflow specified in TS 28.100, i.e. awareness, analysis, decision and execution. MDA role in the management loop is within the scope of analytics (see TS 28.100).
In addition to the above four items included in management control loop or management loop, intent handling is also introduced in TS 28.100 which means certain autonomous network levels are required to support intent driven management control loop autonomously. And in clause 4.2.2 of TS 28.312, intent driven MnS is defined with the capabilities including intent translation and intent fulfilment result/information evaluating, which are the main tasks included in the categorization of intent handling defined in clause 4.3.4 of TS 28.100.
And if Artificial Intelligence/Machine Learning (AI/ML) technology is utilized in autonomous networks, AI/ML model training MnS specified in TS 28.105, can be used to enable analytics or decision autonomy capabilities and thus to achieve certain autonomous network levels.
