Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If drive testing is used to assess mobile radio network performance, then measurement precision and coverage assessment are improved, but cost, time consumption, and statistical relevance deteriorate
Solution Approach 1:
The patent creates a virtual copy of the physical network by collecting and correlating user plane traffic data with control plane signaling data. This digital replica allows comprehensive network assessment without requiring physical drive testing, thereby reducing time consumption while maintaining measurement precision through automated data processing and analysis.
Solution Approach 2:
The patent replaces the mechanical drive testing process with an automated electronic data collection and correlation system. By substituting physical field measurements with automated monitoring of user plane and control plane data, the system eliminates time-consuming manual testing while providing more comprehensive and statistically relevant network performance assessment.
2Device complexity
If control plane signaling data is used for network optimization, then device complexity is reduced, but information completeness and QoS visibility deteriorate
Solution Approach 1:
The patent merges user plane traffic data with control plane signaling data through correlation processes. By combining these two data types, the system achieves complete QoS visibility while maintaining relatively simple device architecture. The merged data provides both the information completeness needed for optimization and the structural simplicity of the monitoring system.
Solution Approach 2:
The patent creates a universal monitoring system that handles multiple functions: collecting user plane data, collecting control plane data, correlating the data, and generating optimization recommendations. This multi-functional approach eliminates the need for separate specialized systems, reducing overall device complexity while providing comprehensive QoS information through the integrated data processing capability.
3Ease of operation
If OSS counters are used for cell-based network monitoring, then ease of operation is improved, but measurement precision and quality distribution visibility deteriorate
Solution Approach 1:
The patent segments the network into granular measurement units by correlating user plane and control plane data at the individual user level before aggregating to cell level. This segmentation allows precise measurement of quality distribution within cells while maintaining ease of operation through automated data processing. The segmented approach provides detailed insights without requiring complex manual analysis.
