If network slice management systems use traditional manual management methods, then management flexibility is maintained, but management efficiency and effectiveness deteriorate

Engineering Contradiction:
Improvemanagement efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables automatic performance assurance through self-service mechanisms where the network slice management function device autonomously receives policy requests, determines appropriate policies, and executes management actions without requiring manual intervention from operators, thereby improving efficiency while maintaining manageable complexity through automation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements closed-loop feedback mechanisms where performance monitoring results feed back into policy determination and adjustment, allowing the management system to automatically optimize network slice performance based on real-time conditions, improving effectiveness without proportionally increasing complexity

Inventive Principle:
Principle #23Feedback

2Reliability

If network slice management systems implement comprehensive performance monitoring, then performance assurance capability is improved, but interaction complexity between management devices increases

Engineering Contradiction:

AI summary

This application discloses a network slice and network slice subnet management method. In the method, a performance assurance policy of a network slice is determined, so that an NSMF device executes the performance assurance policy of the network slice, to implement performance assurance. In addition, a performance monitoring policy of the network slice may also be determined, so that the NSMF device performs performance monitoring on the network slice according to the performance monitoring policy of the network slice, to learn of a running status of the network slice. In addition, the NSMF device may execute the performance assurance policy of the network slice based on a performance monitoring result. This is also similar for a network slice subnet.
