Base Station Access Safety via Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals are vulnerable to accessing fake base stations, which can send scam messages, leading to user deception, as they prioritize signal intensity over authenticity.
Innovation Solution
A method and apparatus that determine a safety factor for each base station based on the matching degree between access parameter values and pre-stored reference values, allowing access only if the safety factor meets a threshold, and adding non-compliant base stations to a forbidden list to prevent fake base station access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal accesses the base station with the maximum signal intensity, then the communication quality is improved, but the terminal may access a fake base station and receive scam messages
Solution Approach 1:
The patent changes the access parameter from signal intensity alone to a composite parameter including signal intensity and safety factor. The safety factor is calculated based on matching degrees of multiple access parameters (system message parameters, cell reselection parameters, etc.) between the detected base station and pre-stored reference values of safe base stations. This parameter transformation allows the terminal to distinguish fake base stations while still selecting the best communication signal.
Solution Approach 2:
The patent introduces a safety factor as an intermediary parameter between signal intensity and base station access decision. The safety factor acts as a mediator that evaluates the authenticity of the base station by comparing access parameters with pre-stored reference values. This intermediary mechanism prevents direct access to fake base stations while maintaining connection to legitimate base stations with optimal signal quality.
2Object-affected harmful factors
If the terminal verifies access parameters to avoid fake base stations, then security is improved, but the access process complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing access parameter reference values of safe base stations in the terminal before actual base station access. These reference values include system message parameters, cell reselection parameters, and other access parameters from legitimate base stations. When a base station is detected, the terminal compares its parameters against the pre-stored references, significantly reducing the complexity of real-time verification and enabling quick identification of fake base stations.
3Object-affected harmful factors
If the terminal continues to access the current base station when parameters do not match, then security is maintained, but communication continuity may be affected
Solution Approach 1:
The patent applies partial action by implementing selective parameter verification rather than complete rejection. When access parameters do not fully match the reference values, the terminal calculates a safety factor based on the degree of matching. If the safety factor exceeds a threshold, the terminal continues accessing the current base station, maintaining communication continuity. This partial verification approach balances security requirements with communication stability, avoiding unnecessary disconnections while still protecting against fake base stations.
