Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If network slice management is performed manually to ensure precise control over configuration parameters, then management precision is improved, but productivity deteriorates due to increased human intervention time and operational complexity
Solution Approach 1:
The network slice subnet instance automatically performs self-optimization by receiving optimization policies from the network slice instance, determining configuration parameter adjustments, and applying modifications autonomously without human intervention. This self-service mechanism resolves the contradiction by enabling the system to maintain precise control while eliminating manual operational overhead.
Solution Approach 2:
The system implements a feedback loop where the network slice subnet instance continuously monitors its own performance and configuration state, compares it against optimization policies, and automatically adjusts parameters to achieve optimal performance. This closed-loop feedback mechanism enables both high precision in parameter management and high productivity through automation.
2Reliability
If network slice instances are configured with fixed parameters to ensure stability, then reliability is improved, but adaptability deteriorates as the system cannot dynamically respond to changing traffic and resource conditions
Solution Approach 1:
The network slice subnet instance transitions from static fixed parameter configuration to dynamic adaptive configuration. The system continuously receives optimization policies from the network slice instance and automatically adjusts configuration parameters based on real-time performance data, traffic conditions, and resource availability. This dynamic approach maintains reliability through controlled adjustments while achieving adaptability to changing conditions.
Solution Approach 2:
The system enables parameter changes by allowing the network slice subnet instance to modify its configuration parameters automatically based on optimization policies. This includes adjusting parameters such as capacity allocation, resource distribution, and performance thresholds. The ability to change parameters dynamically resolves the contradiction by maintaining system reliability through policy-guided adjustments while achieving adaptability to varying operational conditions.
3Extent of automation
If automated self-optimization is implemented to improve productivity and reduce human intervention, then extent of automation is improved, but device complexity increases due to the need for autonomous decision-making capabilities
Solution Approach 1:
The network slice instance serves as an intermediary that manages the complexity of automated optimization. Instead of embedding complex autonomous decision-making logic directly in the network slice subnet instance, the system uses the network slice instance to receive optimization policies, process performance data, and generate configuration adjustments. This intermediary approach enables high automation while managing device complexity by centralizing the intelligence in the managing network device.
