Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods lack effective means to determine the reliability of user location information in wireless communications, leading to potential illegal access due to inaccurate or false location data, especially in satellite-assisted 5G networks.
Innovation Solution
A method and apparatus for determining user location information reliability by analyzing the sending entity, source, trajectory, and analytics results of the location information, with network elements like AMF, MME, and NWDAF involved in verifying and obtaining accurate location data through positioning procedures when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user location information is used for network access verification, then network access efficiency is improved, but reliability of location verification deteriorates due to potential false or inaccurate location data from terminals
Solution Approach 1:
The patent introduces a base station as an intermediary between the terminal and the network for location verification. The base station obtains location information from the terminal and performs verification based on this information, acting as a trusted mediator that can validate location authenticity before network access is granted, thus resolving the contradiction between efficient access and reliable verification
Solution Approach 2:
The patent implements preliminary location verification by the base station before the terminal accesses the network. The base station verifies location information in advance using multiple criteria (sending entity validation, source verification, trajectory analysis, and analytics results), ensuring that only terminals with authentic location data can access the network, thereby preventing illegal access while maintaining efficiency
2Speed
If location verification is performed without reliability determination, then processing speed is improved, but accuracy of location verification deteriorates leading to potential illegal access
Solution Approach 1:
The patent segments the location verification process into multiple independent evaluation dimensions: sending entity validation, source verification, trajectory analysis, and analytics result assessment. The base station can selectively apply these segmentation criteria based on network conditions, allowing fast verification when simple checks suffice and more rigorous multi-criteria evaluation when higher accuracy is needed, thus balancing speed and precision

AI summary
Disclosed in the embodiments of the present application are a credibility determination method for user position information, and an apparatus therefor, which can be applied to communication systems such as the long term evolution (LTE) system, the 5th generation (5G) mobile communication system, the 5G new radio (NR) system, or other future novel mobile communication systems. The method comprises: acquiring user position information of a terminal device; and determining whether the user position information is credible. Implementing the embodiments of the present application can determine, by means of the transmission subject, the source, the trajectory and the analysis result of the user position information, whether the user position information is credible, thereby helping to improve the credibility of the position information and more accurately acquire the positions of UEs.
