Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If terminal-based positioning method is used, then positioning speed and terminal autonomy are improved, but positioning reliability and security deteriorate due to false measurement data or tampered results
Solution Approach 1:
The patent implements a feedback mechanism where the network side receives positioning results from the terminal, verifies them against independently obtained positioning information, and sends back verification results or corrected positioning data. This closed-loop feedback ensures terminal autonomy while maintaining network-side validation to prevent false data, thus resolving the contradiction between terminal-based speed and reliability.
Solution Approach 2:
The network side acts as an intermediary that receives positioning information from both the terminal and independent network measurements, compares these sources, and determines the final reliable positioning result. This intermediary role allows terminal-based positioning to proceed quickly while the network verifies accuracy, balancing speed and reliability.
2Loss of time
If terminal-based positioning method is used, then terminal autonomy and response time are improved, but positioning accuracy and security deteriorate
Solution Approach 1:
The network side performs preliminary preparation by having pre-configured positioning information and verification mechanisms ready. When terminal positioning results are received, the verification can proceed immediately using pre-prepared data, reducing overall response time while ensuring accuracy through pre-established validation rules.
Solution Approach 2:
The system implements rapid feedback where the network side quickly verifies terminal positioning results against independently obtained data and returns verification outcomes. This fast feedback loop maintains short response time while ensuring positioning accuracy through immediate validation.
3Reliability
If network-assisted positioning is used, then positioning reliability is improved, but positioning speed and terminal autonomy deteriorate
Solution Approach 1:
The patent applies partial network assistance where the terminal performs positioning measurements autonomously and sends results to the network for verification. The network performs partial validation rather than complete re-measurement, providing sufficient reliability assurance while minimizing additional processing time, thus balancing reliability and speed.
4Speed
If terminal reports false measurement data, then positioning speed is maintained, but positioning accuracy and security deteriorate
Solution Approach 1:
The network side implements feedback verification where terminal positioning results are automatically checked against independently obtained positioning information. If false data is detected, the network sends correction instructions or rejects the false results, maintaining positioning speed while ensuring accuracy through continuous validation feedback.
Solution Approach 2:
The network side serves as an intermediary verification layer that receives terminal positioning reports, compares them with independently measured positioning data, and determines authentic results. This intermediary validation maintains terminal-based positioning speed while preventing false data from affecting accuracy.

AI summary
Embodiments of this application provide a terminal device location determining method and a device. The method includes: obtaining location information reported by a terminal device and location information reported by a base station; determining location information of the terminal device based on the location information reported by the terminal device and the location information reported by the base station; and sending a positioning response to an application function entity or an external client by using a gateway mobile location center, where the positioning response includes the location information of the terminal device. According to the method provided in the embodiments of this application, whether a location of the terminal device is incorrect is determined by comparing the location information provided by the base station with the location information provided by the terminal device, so that positioning accuracy and reliability can be both considered.
