Positioning Server Measurement Assistance for 5G Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G terminal positioning technologies face challenges in reducing time delay, which affects user experience and service requirements, particularly in Release 17 of 5G networks where shorter time delays are necessary.
Innovation Solution
A positioning measurement method where measurement assistance information is directly sent from a positioning server to a serving base station, allowing the base station to determine a measurement gap for the terminal's positioning measurement, thereby reducing transmission delays and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If measurement assistance information is sent from positioning server to terminal and then to base station, then the terminal can perform positioning measurement, but the transmission delay increases
Solution Approach 1:
The patent extracts the measurement assistance information from the terminal and sends it directly from the positioning server to the base station, eliminating the intermediate transmission step through the terminal. This reduces the information transmission path and minimizes positioning measurement delay while maintaining system functionality.
Solution Approach 2:
The patent introduces a direct communication channel between the positioning server and base station as an intermediary path for measurement assistance information. This bypasses the traditional terminal-mediated transmission route, reducing overall transmission delay while keeping the terminal involved in the positioning measurement process.
2Measurement precision
If the terminal performs positioning measurement with detailed measurement gap configuration, then the positioning precision improves, but the time delay increases
Solution Approach 1:
The patent applies preliminary action by having the base station determine the measurement gap configuration in advance based on measurement assistance information from the positioning server, before the terminal performs the actual positioning measurement. This pre-configuration reduces the time required during the measurement process itself while ensuring sufficient precision through proper gap settings.
