Terminal Position Reporting in Non-Territorial Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Non-Territorial Networks (NTNs), there is a challenge in ensuring privacy and accurate position reporting of terminals while maintaining normal communication, as existing methods may invade terminal privacy and fail to provide appropriate services due to inaccurate or unreported positions.
Innovation Solution
The method involves terminals reporting low-precision or privacy-removed position information, such as area IDs, offset positions, or anchor IDs to network devices, which allows for appropriate service selection, like choosing a core network node, without revealing precise locations, ensuring continuous communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise position information is reported, then service accuracy is improved, but terminal privacy is compromised
Solution Approach 1:
The patent changes the precision parameter of position information from high to low by reporting area IDs instead of precise coordinates. This allows the system to maintain functional service requirements while reducing privacy invasion, as the position is reported at a coarse granularity level that does not reveal exact terminal locations
Solution Approach 2:
The patent extracts only the necessary portion of position information (area ID) required for service selection, while leaving out the precise location data. This extraction approach provides sufficient information for network service routing without exposing detailed terminal position data that would compromise privacy
2Object-affected harmful factors
If low-precision position information is reported, then privacy is protected, but service selection accuracy deteriorates
Solution Approach 1:
The patent transitions from reporting position in continuous coordinate space to discrete area ID space. This dimensional transformation allows the system to work with coarse-grained position information that is sufficient for service area identification and selection, maintaining functional accuracy without requiring precise location data
3Object-affected harmful factors
If position information is not reported, then privacy is protected, but communication service continuity deteriorates
Solution Approach 1:
The patent uses inexpensive area ID information as a substitute for precise position data. This low-cost position representation provides sufficient information for maintaining communication service continuity in NTN scenarios without requiring complex or precise positioning systems
