Core Network Positioning Message Integration for 5G Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal positioning technologies in 5G networks face challenges in reducing end-to-end delay, which affects user experience and service demands, particularly in Release 17 where a 10-millisecond delay is proposed, compared to the existing 50-milliseconds delay.
Innovation Solution
A method where a core network element sends a single message to a terminal that includes both auxiliary positioning information and location request information, allowing the terminal to perform positioning measurement and obtain a positioning result, thereby reducing the number of messages needed and shortening the end-to-end delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple separate positioning messages are sent to the terminal, then the positioning information can be transmitted accurately, but the end-to-end delay increases to 50 milliseconds
Solution Approach 1:
The patent combines auxiliary positioning information and location request information into a single integrated positioning message transmitted from the network to the terminal. This merging of multiple information types into one message reduces the number of message exchanges required, directly decreasing the end-to-end positioning delay from 50 milliseconds to meet the 10-millisecond requirement for 5G Release 17 services.
2Productivity
If a single integrated positioning message is sent, then the end-to-end delay is reduced to 10 milliseconds, but the message structure becomes more complex
Solution Approach 1:
Within the single integrated positioning message, the patent segments information into distinct functional fields: auxiliary positioning information (including positioning reference signal resource configuration, reference signal time difference, and reference signal received power) and location request information. This internal segmentation allows the message to convey comprehensive positioning data in one transmission while maintaining clear structure for processing, achieving both speed and manageability.

AI summary
Terminal positioning methods and communication devices are provided. In one terminal positioning method, a core network element sends a first message to be used by a terminal to perform terminal positioning, where the first message includes auxiliary positioning information and location request information, the auxiliary positioning information is used by the terminal to perform positioning measurement, and the location request information is used to request and acquire a positioning result of the positioning measurement.
