Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional drive test methods are used for network optimization, then measurement data can be obtained, but heavy human resource, material resource and fund investments are required
Solution Approach 1:
The patent uses terminal devices (mobile phones) to copy the measurement function of expensive drive test instruments. Instead of using specialized DT equipment with professional operators, ordinary terminals perform MDT measurements, creating a virtual copy of the measurement capability that eliminates the need for heavy resource investment while maintaining measurement effectiveness.
Solution Approach 2:
The patent enables terminals to autonomously perform MDT measurements and report data without requiring professional operators. The terminal itself serves as both the measurement instrument and the data collector, eliminating the need for human resource investment in drive test operations and enabling automated network optimization.
2Measurement precision
If conventional drive test methods are used for network optimization, then network problems can be identified, but very high requirement on experience of network optimization worker is needed
Solution Approach 1:
The system enables automated MDT configuration and execution where terminals autonomously perform measurements and report data. The core network device automatically configures measurement parameters, selects measurement targets, and collects results without requiring manual intervention by experienced optimization workers, thereby eliminating the high experience requirement while maintaining problem detection capability.
Solution Approach 2:
The core network device pre-configures MDT measurement parameters, measurement targets, and reporting mechanisms before terminals perform measurements. This preliminary configuration automates the complex decision-making process that previously required experienced workers, allowing any operator to execute standardized measurement tasks with consistent results.
3Adaptability or versatility
If existing MDT technologies are used, then measurements can be performed, but BT and WLAN measurements indoors cannot be performed due to lack of core network device configuration capabilities
Solution Approach 1:
The patent extends MDT measurement capability to multiple network types (LTE, BT, WLAN) and multiple environments (indoor, outdoor) through a unified core network configuration mechanism. The core network device can configure measurement parameters for different radio access technologies and measurement targets, making the MDT system universal across diverse measurement scenarios while maintaining reliable data collection through standardized reporting procedures.
