Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic map information is used for road user recognition, then recognition accuracy is improved, but data costs, storage costs, and maintenance costs increase
Solution Approach 1:
The patent extracts the essential positioning function from electronic map dependency by using AGPS measurement reports and base station positioning information. This allows road user recognition to be performed using only user equipment position data, eliminating the need to store and process large electronic map datasets while maintaining recognition capability.
Solution Approach 2:
The patent replaces expensive electronic map data with cheaper, transient positioning measurements. AGPS measurement reports and base station positioning information are used as temporary, on-demand data sources that do not require long-term storage or expensive licensing, thereby reducing data and storage costs.
2Measurement precision
If electronic map information is used for road user recognition, then recognition accuracy is improved, but deployment scenarios are limited
Solution Approach 1:
The patent removes the constraint of electronic map dependency from the road user recognition system. By extracting only the necessary positioning information from AGPS reports and base station data, the system becomes adaptable to various deployment scenarios including base stations with limited storage capacity, where electronic maps cannot be deployed.
Solution Approach 2:
The patent creates a universal road user recognition method that can be deployed in multiple scenarios: base stations with limited storage, networks with varying electronic map availability, and different geographic regions. The method uses universally available AGPS and base station positioning information rather than region-specific electronic maps.
3Reliability
If electronic map information is used for road user recognition, then road user identification is improved, but maintenance costs increase
Solution Approach 1:
The patent replaces expensive, hard-to-maintain electronic map data with cheaper, easily updated positioning measurements. AGPS measurement reports and base station positioning information can be obtained on-demand without requiring manual map updates or maintenance, significantly reducing operational maintenance costs.

AI summary
A road user recognition method and device, a storage medium, and an electronic device are provided. The method includes: extracting Measurement Report (MR) data within a preset time period (S202); obtaining target MR data carrying an Assisted Global Positioning System (AGPS) measurement result from the MR data (S204); and performing road user recognition based on the target MR data (S206). The method solves the problem in the related art that the recognition of road users based on electronic map information of roads relies on the electronic map information, which increases data costs, storage costs, and maintenance costs, and limits scenarios in which a road user recognition function can be deployed. Road users can be recognized without external electronic map information provided by a third party, which decreases data costs as well as storage and maintenance costs, and makes deployment scenarios more flexible.
