Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network slice management systems use traditional manual management methods, then management flexibility is maintained, but management efficiency and effectiveness deteriorate
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
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
2Reliability
If network slice management systems implement comprehensive performance monitoring, then performance assurance capability is improved, but interaction complexity between management devices increases
Solution Approach 1:
The decision management function device is designed as a universal multi-functional component that consolidates multiple management capabilities including performance monitoring, policy determination, and execution control into a single device, reducing interaction complexity while maintaining comprehensive performance assurance capability
Solution Approach 2:
The decision management function device acts as an intermediary between the network slice management function device and the performance monitoring functions, centralizing the interaction point and simplifying the overall system architecture by reducing the number of direct interactions required between multiple management devices

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.
