Core Network Consent Updates for NTN Location Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-terrestrial networks, base stations struggle to accurately determine the location of terminals due to the large coverage area of satellites, leading to potential privacy leaks and resource wastage when sending configuration information for location reporting to terminals that do not consent.
Innovation Solution
A method where a first core network device subscribes to a second core network device for change notifications regarding user consent information, allowing timely updates to user consent information, ensuring accurate determination of whether terminals consent to report location information, thereby preventing privacy leaks and resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base station sends location reporting configuration to all terminals, then location service coverage is improved, but privacy leaks and resource wastage occur for non-consenting terminals
Solution Approach 1:
The system performs preliminary action by obtaining user consent information before sending location reporting configuration. The core network device queries whether the terminal has consented to location information reporting in advance, and only sends configuration to consenting terminals, thereby preventing privacy leaks and resource wastage while maintaining service coverage for authorized users
Solution Approach 2:
The system implements feedback mechanism where the core network device continuously obtains updated user consent information from the authentication and authorization server. This feedback loop ensures that the base station receives real-time information about terminal consent status and adjusts its behavior accordingly, sending location reporting configuration only to terminals that have currently consented
2Area of stationary object
If base station uses satellite communication with large coverage area, then communication range is improved, but location determination precision deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (core network device with consent management system) that operates between the base station and terminal. This intermediary obtains and manages user consent information, enabling the base station to selectively send location reporting configuration only to terminals that have consented, thus maintaining large coverage area while improving effective location service precision through targeted delivery
3Productivity
If base station sends location reporting configuration to terminals, then location service availability is improved, but resource wastage occurs for non-consenting terminals
Solution Approach 1:
The system performs preliminary action by obtaining user consent information before sending location reporting configuration. The core network device queries whether the terminal has consented to location information reporting in advance, and only sends configuration to consenting terminals, thereby preventing resource wastage while maintaining service availability for authorized users
Solution Approach 2:
The system implements feedback mechanism where the core network device continuously obtains updated user consent information from the authentication and authorization server. This feedback loop ensures that the base station receives real-time information about terminal consent status and adjusts its behavior accordingly, sending location reporting configuration only to terminals that have currently consented, thus avoiding resource wastage

AI summary
A notification subscription method is performed by a first core network device and includes: subscribing, to a second core network device, a change notification regarding user consent information of a terminal, wherein the user consent information indicates whether the terminal consents to report location information.
