Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automation and network management are implemented in 5G and 6G networks, then service level agreement assurance capability is improved, but network complexity and resource consumption increase
Solution Approach 1:
The patent extracts the service level agreement management functionality from the complex domain controller and implements it as a standalone network function. This separation allows SLA assurance to operate independently with dedicated resources, reducing the overall network management complexity while maintaining reliability.
Solution Approach 2:
The network management system is segmented into distinct functional components, with the service level agreement function operating as an independent module. This segmentation enables targeted optimization of SLA management without affecting other network functions, thereby improving reliability while controlling complexity.
2Reliability
If comprehensive service level agreement monitoring is implemented across all network domains, then service quality is improved, but resource consumption increases
Solution Approach 1:
The service level agreement function is designed as a universal network function that can serve multiple network domains (radio access network, core network, transport network) simultaneously. This multi-functionality allows comprehensive service quality monitoring across all domains using a single resource-efficient mechanism, avoiding redundant monitoring processes.
Solution Approach 2:
The service level agreement function autonomously performs monitoring, measurement, and violation detection without requiring intensive external resource allocation. The function self-manages its operations, efficiently utilizing network resources while maintaining comprehensive service quality assurance.
3Measurement precision
If real-time service level agreement measurements are performed, then service level violation detection is improved, but processing time and resource usage increase
Solution Approach 1:
The service level agreement function implements continuous real-time monitoring of service levels across the network. By maintaining uninterrupted measurement operations, the system achieves high measurement precision for detecting service level violations without periodic delays, while the efficient architecture minimizes processing overhead.
Solution Approach 2:
The function continuously measures service levels and provides immediate feedback on violations to relevant network functions. This real-time feedback mechanism ensures high measurement precision for violation detection while the direct feedback path minimizes processing time delays.
4Stability of the object's composition
If domain controller interaction is required for network adjustments, then centralized control is improved, but response time and operational efficiency decrease
Solution Approach 1:
The service level agreement function is pre-configured with the authority and capability to initiate network adjustments directly when service level violations are detected. This preliminary authorization eliminates the need for time-consuming domain controller interaction for routine adjustments, significantly improving response time while maintaining centralized control stability through predefined policies.
Solution Approach 2:
The service level agreement function autonomously initiates and executes network adjustments without requiring domain controller intervention. This self-service capability dramatically improves network adjustment efficiency and response time, while centralized control stability is maintained through pre-established control policies and oversight mechanisms.
