User Terminal GNSS Location Reporting for Mobile Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MDT technology lacks guaranteed accuracy in location information, leading to unreliable measurement data reported by user terminals in mobile communication systems.
Innovation Solution
A mobile communication system where a base station requests user terminals to provide detailed location information using GNSS, and the terminals include this information in their measurement reports only if available, ensuring accurate location data is reported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user terminals use conventional location information methods, then device complexity is reduced, but measurement precision and reliability of location data deteriorate
Solution Approach 1:
The patent introduces GNSS (Global Navigation Satellite System) as an intermediary positioning method to obtain accurate location information. Instead of relying on conventional network-based positioning, the terminal uses GNSS receiver to acquire precise location data through satellite signals, thereby improving measurement precision without significantly increasing terminal complexity
Solution Approach 2:
The patent replaces conventional network-based positioning mechanisms with GNSS satellite-based positioning. This substitution enables the terminal to independently obtain accurate location information through satellite signals, improving reliability while maintaining acceptable device complexity
2Reliability
If user terminals always acquire detailed location information, then measurement data reliability improves, but energy consumption increases
Solution Approach 1:
The patent implements dynamic control of GNSS receiver operation. The terminal activates the GNSS receiver only when accurate location information is required for measurement reporting, and deactivates it when not needed. This dynamic on/off control ensures measurement data reliability while minimizing energy consumption
Solution Approach 2:
The patent uses location information availability as a trigger mechanism to accelerate the acquisition process. When the terminal determines that location information is needed for measurement reporting, it immediately activates GNSS to quickly obtain the data, then stops acquisition to conserve energy
3Loss of information
If user terminals report location information with every measurement, then information completeness improves, but loss of time due to processing increases
Solution Approach 1:
The patent extracts location information from the general measurement data package. Instead of including all possible measurement parameters in every report, the terminal selectively extracts and reports only the relevant location information when needed, reducing processing time while maintaining information completeness for location-dependent measurements

AI summary
A user terminal includes: a transmitter that transmits a measurement report including a measurement result of radio environments, to a base station; a receiver that receives request information requesting the user terminal to make detailed location information available using GNSS (Global Navigation Satellite System), from the base station; and a controller that attempts to make the detailed location information available so as to include the detailed location information in the measurement report, in a case where the receiver receives the request information.
