Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all devices are selected for measurement, then measurement coverage is improved, but measurement complexity and processing time increase
Solution Approach 1:
The patent segments the plurality of devices into multiple subsets based on features such as device type, mobility state, and service type. Instead of processing all devices uniformly, the system divides them into manageable groups (e.g., first subset, second subset) that can be measured and processed separately, reducing overall complexity while maintaining comprehensive coverage.
Solution Approach 2:
The patent applies different measurement and processing approaches to different device subsets based on their specific characteristics. For example, mobile devices may receive different measurement configurations than stationary devices, allowing each subset to be measured with appropriate precision while optimizing overall system efficiency.
2Measurement precision
If device selection is based on multiple features, then navigation accuracy is improved, but information processing requirements increase
Solution Approach 1:
The patent extracts and utilizes specific relevant features from device information such as device type, mobility state, and service type to make selection decisions. Rather than processing all available device data, the system identifies and uses only the key features necessary for accurate navigation model enhancement, reducing information processing requirements while maintaining navigation accuracy.
3Measurement precision
If device subsets are selected for navigation model enhancement, then positioning accuracy is improved, but system resource consumption increases
Solution Approach 1:
The patent implements partial action by selecting only specific device subsets that are most beneficial for navigation model enhancement, rather than using all available devices. This selective approach achieves improved positioning accuracy while consuming fewer system resources, as the system processes only the necessary portion of device data required for effective model enhancement.

AI summary
Aspects presented herein may improve the performance of mobile/computer applications. Aspects presented herein may enable mobile/computer applications to differentiate entities that are associated with UEs or entities running the navigations applications, thereby enabling the mobile/computer applications (or their associated servers) to have a more accurate understanding of the conditions surrounding the UEs and their users. In one aspect, a network node obtains first information including at least one feature associated with a plurality of devices. The network node selects a first subset of the plurality of devices for a measurement based on the at least one feature associated with the plurality of devices (or the network node may exclude a second subset of the plurality of devices from the measurement).
