Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively detecting and protecting against fake relay stations in telecommunication networks, particularly in wireless networks, as they often rely on complex and uncertain processing methods.
Innovation Solution
A detection and protection system that includes a core network with a threat detection device equipped with a radio terminal and a processor. This system performs wireless signal scanning, decodes the information, and compares the identification information of signal relay stations with a white list to identify fake relay stations, sending an alarming message when detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional detection methods using OTDOA messages and distance calculation are used, then fake base stations can be detected, but the detection process becomes complex and requires multiple calculation steps
Solution Approach 1:
The patent extracts and compares only the essential identification information (cell ID, frequency, bandwidth) from wireless signals against a white list, removing the need for complex OTDOA distance calculations. This extraction approach maintains detection reliability while significantly simplifying the detection process.
Solution Approach 2:
Instead of calculating distances to verify authenticity, the patent inverts the approach by directly comparing identification information against a pre-established white list of legitimate relay stations. This inversion eliminates complex calculations while maintaining detection effectiveness.
2Reliability
If a blacklist of prohibited networks is used as in TW 1757827, then known fake relay stations can be blocked, but new fake relay stations may not be detected and the processing becomes complicated
Solution Approach 1:
The patent performs preliminary action by pre-compiling a white list of legitimate relay station identification information before detection begins. This allows the system to proactively identify and block both known and unknown fake relay stations by comparing against the established white list, rather than reacting only to blacklisted entities.
Solution Approach 2:
The patent converts the limitation of not knowing all fake relay station identities into a benefit by using a white list approach. Any relay station not on the white list is automatically flagged as potential fake, turning the unknown nature of fake stations into a detectable anomaly rather than an undetectable threat.
3Measurement precision
If comprehensive wireless signal scanning and white list comparison is performed, then detection accuracy improves, but processing time increases
Solution Approach 1:
The patent extracts only the most critical identification elements (cell ID, frequency, bandwidth) from wireless signals for comparison, rather than analyzing entire signal profiles. This extraction maintains high identification accuracy while significantly reducing processing time and computational resources required.
Solution Approach 2:
The patent applies partial action by comparing only essential identification parameters against the white list rather than performing exhaustive signal analysis. This partial comparison achieves sufficient detection accuracy for security purposes while minimizing processing time and resource consumption.
