Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning assistance data is provided for multiple regions, then positioning accuracy is improved, but processing power consumption increases
Solution Approach 1:
The patent segments positioning assistance data by associating different data sets with specific geographic areas. The network divides the service area into multiple regions, each with its own positioning assistance data profile, allowing user equipment to selectively process only the data relevant to its current location, thereby reducing overall processing power consumption while maintaining positioning accuracy.
Solution Approach 2:
The patent implements local quality by providing customized positioning assistance data for specific geographic regions rather than using a uniform approach. Each area has tailored assistance data profiles that contain only the necessary information for that particular region, reducing the processing burden on user equipment while improving positioning accuracy through location-specific optimizations.
2Measurement precision
If positioning assistance data is provided for multiple regions, then positioning accuracy is improved, but positioning latency increases
Solution Approach 1:
By segmenting positioning assistance data into region-specific profiles, the system enables user equipment to quickly identify and process only the relevant data for its current location. This segmentation reduces the time required to acquire and process positioning data, thereby decreasing positioning latency while maintaining accuracy through region-specific optimizations.
Solution Approach 2:
The network performs preliminary actions by pre-configuring and storing multiple positioning assistance data profiles associated with different geographic areas before user equipment needs them. When positioning is required, user equipment can immediately access the pre-prepared data for its current region without waiting for real-time generation or processing of assistance data, thus reducing positioning latency.
3Productivity
If regional positioning assistance data is implemented, then data efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal framework where a single positioning system can serve multiple geographic regions by using a standardized mechanism for associating positioning assistance data with area identifiers. This multi-functional approach allows the same system infrastructure to efficiently handle different regions' requirements, improving data efficiency while keeping system complexity manageable through standardization.
