User Terminal Positioning Data Collection and Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning techniques in mobile devices are limited by the availability of only outdated and limited positioning information, which restricts the accuracy of fingerprinting methods and lacks the capability to initiate and report additional position-related measurements independently within the user terminal.
Innovation Solution
The user terminal is configured to initiate and perform additional position-related measurements, such as SFN-SFN, E-OTD, and inter-RAT measurements, and report them to an external server or communication network, using software interfaces to mimic RRC or RRLP protocols, allowing for enhanced positioning data collection beyond traditional RAN instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user terminal relies on traditional RAN instructions for positioning measurements, then the system complexity is reduced and ease of operation is improved, but the positioning accuracy deteriorates due to limited and outdated positioning information
Solution Approach 1:
The user terminal is empowered to autonomously initiate and perform position-related measurements without requiring continuous instructions from the Radio Access Network. The terminal independently determines what measurements to take, when to take them, and how to report them, making the system self-sufficient at the terminal level while improving positioning accuracy through more timely and relevant measurement data
2Loss of information
If the user terminal independently initiates and reports additional position-related measurements, then the positioning accuracy is improved through enhanced data collection, but the device complexity increases due to additional measurement capabilities
Solution Approach 1:
The user terminal pre-configures itself with the capability to perform various position-related measurements (such as SFN-SFN, E-OTD, and inter-RAT measurements) before they are needed. By having these measurement capabilities ready in advance and autonomously activating them based on positioning needs, the terminal ensures that relevant positioning information is available without requiring complex real-time coordination with the network
Solution Approach 2:
The user terminal dynamically adapts its measurement and reporting behavior based on current positioning requirements. Rather than continuously performing all possible measurements, the terminal selectively initiates measurements based on what is needed for accurate positioning at any given moment, optimizing the balance between information availability and device complexity
Data Source
AI summary
A system, computer software and method for collecting, in addition to position data, additional positioning data in a user terminal served by a communication network. The method includes initiating, by generating a message within the user terminal, collection of the positioning data, where the positioning data includes information based on which a physical location of the user terminal is determined; measuring, by the user terminal, at least one parameter related to the physical location of the user terminal in response to the message; producing, within the user terminal, measurement reports that include the at least one parameter; selecting, within the user terminal, one or more measurement reports that were generated in response to the message generated by the user terminal; reporting the selected one or more measurement reports to an interface within the user terminal; and transmitting, from the interface, the reported one or more measurement reports to an external server or to the communication network.
