Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing MDT technology is applied to indoor scenarios, then outdoor network optimization can be maintained, but indoor network optimization fails due to lack of Bluetooth device measurement capability
Solution Approach 1:
The patent introduces dynamic measurement configuration by enabling the network to flexibly configure UE to perform Bluetooth device measurements indoors through MDT configuration signaling, while maintaining traditional outdoor GPS-based MDT operations. This dynamic adaptability allows the system to switch measurement methodologies based on scenario requirements.
Solution Approach 2:
The patent segments the MDT measurement process into scenario-specific components: outdoor scenarios continue to use GPS-based positioning and traditional measurements, while indoor scenarios utilize Bluetooth device measurements. This segmentation allows each scenario to use the most appropriate measurement technology without compromising the other.
2Loss of information
If MDT configuration signaling is extended to include Bluetooth measurement events, then UE can report Bluetooth device information, but signaling complexity increases
Solution Approach 1:
The patent applies universality by extending the existing MDT configuration signaling framework to handle both traditional measurements and new Bluetooth device measurements through a unified configuration structure. The measurement configuration signaling serves multiple functions: configuring GPS-based outdoor measurements and Bluetooth-based indoor measurements within the same protocol framework, reducing the need for separate signaling mechanisms.
Solution Approach 2:
The patent modifies existing MDT configuration parameters to include Bluetooth measurement capabilities. By changing the measurement event parameters to include Bluetooth-specific measurement types (such as Bluetooth device identification and signal strength measurements), the system can convey additional information without creating entirely new signaling structures.
3Measurement precision
If UE performs Bluetooth device measurements indoors, then indoor positioning accuracy improves, but measurement precision challenges arise due to Bluetooth signal characteristics
Solution Approach 1:
The patent uses the UE as an intermediary device that collects Bluetooth measurement data in challenging indoor environments and relays this information to the network. The UE's measurement capabilities serve as a bridge between Bluetooth devices and the network, enabling indirect measurement and reporting of Bluetooth signal characteristics that would be difficult to obtain directly.
Solution Approach 2:
The patent implements feedback mechanisms where the network configures UE to perform Bluetooth measurements and receives measurement reports containing Bluetooth device information and signal strength data. This feedback loop allows the network to continuously optimize indoor positioning accuracy based on actual measurement results and adjust measurement configurations accordingly.
