Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual drive-test is adopted to check network coverage quality and system performance, then measurement precision is improved, but loss of time and loss of energy increase due to manual labor requirements
Solution Approach 1:
The system enables user equipment to automatically perform measurements and generate measurement reports without manual intervention. The UE autonomously determines when measurements are needed based on triggering conditions and automatically transmits reports to the network, eliminating the need for manual drive-tests while maintaining measurement accuracy.
Solution Approach 2:
The patent replaces the mechanical manual drive-test process with an automated electronic measurement system. Instead of physical vehicles traveling through coverage areas, the system uses electronic measurement reports generated by user equipment to assess network coverage quality and system performance.
2Measurement precision
If manual drive-test is conducted outdoors, then measurement precision is improved for outdoor coverage, but adaptability deteriorates because indoor and private area optimization cannot be performed
Solution Approach 1:
The measurement system is designed to be universally applicable across multiple environments including outdoor, indoor, and private areas. The same measurement framework and reporting mechanisms work for all locations, enabling the system to optimize network coverage quality across diverse scenarios without requiring location-specific procedures.
3Productivity
If MDT measurement configuration is activated without checking execution object conditions, then productivity is improved by continuous measurement, but loss of energy increases due to unnecessary operations
Solution Approach 1:
The system performs preliminary evaluation of triggering conditions before activating MDT measurements. By assessing whether measurement activation is necessary based on predefined conditions, the system avoids unnecessary measurements and associated energy consumption while maintaining the ability to perform continuous measurement when needed.

AI summary
A method and a device of processing abnormality configuration of MDT are provided. The method includes receiving first information related to MDT-measurement configuration sent by a network operation-administration-and-management entity or a network node of a core network, wherein the first information related to MDT-measurement configuration includes at least MDT-tracking report information; activating an MDT-measurement execution object to perform MDT measurement if the MDT-measurement execution object satisfies an MDT measurement condition in the MDT-tracking report information; not activating the MDT-measurement execution object to perform MDT measurement if the MDT-measurement execution object does not satisfy the MDT measurement condition in the MDT-tracking report information.
