Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location determination is performed using base station signaling and active sets, then location accuracy is improved, but device privacy protection deteriorates
Solution Approach 1:
The patent introduces a location determination system that acts as an intermediary between base station signaling and location data processing. This system receives signaling from base stations, extracts active set information, and determines device locations without directly accessing or storing sensitive user information. The intermediary approach enables location determination while maintaining privacy by processing only the necessary signaling data rather than full user profiles.
Solution Approach 2:
The patent extracts only the necessary information (active sets) from base station signaling to determine device locations. By taking out only the minimal required data elements rather than processing complete user information, the system achieves location accuracy while minimizing privacy intrusion. The extraction process isolates location-relevant parameters from broader communication data.
2Measurement precision
If comprehensive user information is collected for accurate location tracking, then location precision is improved, but information loss and privacy violations increase
Solution Approach 1:
The patent applies partial action by collecting and processing only the portion of information necessary for location determination - specifically active set data from base station signaling. This selective data collection approach provides sufficient location precision without the excessive data gathering that would cause privacy information loss. The system does what is minimally required rather than attempting comprehensive data collection.
