Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slices are manually designed and configured, then service requirements can be met, but the complexity and time for deployment increases significantly
Solution Approach 1:
The system enables automatic network slice generation where the network slice management function autonomously determines template selection, node substitution, and descriptor generation without manual intervention, making the system self-configuring based on service requirements
Solution Approach 2:
Network slice templates are pre-defined with abstract node structures and relationships. These templates prepare common configuration patterns in advance, allowing rapid instantiation when service requirements match the template criteria, reducing real-time design complexity
2Adaptability or versatility
If network slices are customized for each service, then service-specific requirements are satisfied, but the time and resources for slice generation increase
Solution Approach 1:
The network slice configuration is segmented into templates (reusable patterns) and instances (specific deployments). Templates capture common service requirement patterns, allowing multiple service instances to share the same template structure, reducing redundant customization work
Solution Approach 2:
Network slice templates are designed to be universal and service-type-agnostic, capable of supporting multiple different service types through configuration parameters. A single template can serve multiple services by substituting specific node instances, enhancing both adaptability and generation efficiency
3Adaptability or versatility
If abstract nodes are used in network slice templates, then template reusability improves, but the precision of node selection for specific services decreases
Solution Approach 1:
The template maintains abstract node definitions for structural consistency and reusability, while the instantiation process applies local quality by substituting specific node instances that match service-specific requirements. Each service receives precisely matched nodes while preserving the universal template structure
Solution Approach 2:
The system transitions from abstract node parameters in templates to concrete node parameters in instances through parameter substitution. The same template can generate different instances by changing node selection parameters based on service requirements, maintaining both reusability and precision
