28.1003GPPLevels of autonomous networkManagement and orchestrationRelease 17TS

Level 0:

– All the tasks in the fault management workflow (Task A, Task B, Task C, Task D, Task E, Task F, Task G, Task H, Task I, Task J, Task K) are accomplished by human.

Level 1:

– Telecom system executes the tasks of fault related information collection to collect part of fault related information (including alarm information, performance metric, configuration data) (Task C) automatically based on predefined data collection control information, and the tasks of fault management action execution (Task K) based on specified fault recovery control information. Telecom system can also execute the tasks of alarm filtering (Task D) based on specified alarm filtering control information.

– All the other tasks in the fault management workflow (Task A, Task B, Task E, Task F, Task G, Task H, Task I, Task J) are accomplished by human.

Level 2:

– Compared to Level 1, telecom system can additionally executes the tasks of fault recognition (Task E) and fault demarcation (Task G) based on specified fault recognition and demarcation control information. In this level, telecom system can collect all fault related information (including environment data) based on specified data collection control information (Task C).The tasks of fault management action execution (Task J) is fully accomplished by telecom system.

– All the other tasks (Task A, Task B, Task F, Task H, Task I, Task J) are accomplished by human.

Level 3:

– Compared to Level 2, telecom system can additionally execute the tasks of fault root cause analysis based on specified fault root cause analysis control information (Task H). For certain network faults, telecom system can also additionally execute the tasks of fault prediction (Task F), fault recovery mechanism analysis (Task H) and action evaluation and determination(Task I) based on specified fault management control information (i.e. control information for fault prediction, fault recovery mechanism analysis, fault recovery mechanism decision). The tasks of fault related information collection (Task C),alarm filtering (Task D), fault recognition (Task E) and fault demarcation (Task G) are fully accomplished by telecom system.

– All the other tasks (Task A, Task B) are accomplished by human.

Level 4:

– Compared to Level 3, for certain scenario, telecom system additionally execute the tasks of fault management control information generation (Task A) and fault management intent fulfilment information evaluation (Task B) based on specified intent handling control information. The tasks of fault prediction (Task F), fault root cause analysis (Task H), fault recovery mechanism analysis (Task I) and action generation (Task J) are accomplished automatically by telecom system without human intervention.

– Intent handling control information can be pre-defined and specified by human.

Level 5:

– The entire fault management workflows is accomplished by telecom system without human intervention and human predefined control information.

– Human can optionally supervise the fault management action generated by telecom system.
