Vehicle Relay Base Station Authentication for Secure Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relay systems cannot accurately determine whether a communication terminal is within a facility, leading to potential unauthorized access to connection services.
Innovation Solution
A relay system with an authentication device connected to a base station and a relay base station mounted on a vehicle, which determines whether a registered identifier of a communication terminal possessed by a user in the vehicle matches an identifier received from the relay base station. The system generates a permission signal to permit or deny relay of wireless communication based on this determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If distance-based authentication is used to determine facility presence, then communication terminals can connect to the Internet, but unauthorized terminals outside the facility may gain access
Solution Approach 1:
The patent introduces a reader as an intermediary device that detects identifiers of terminals possessed by users in the vehicle. This mediator provides accurate authentication by distinguishing between terminals inside and outside the facility, resolving the contradiction between ease of connection and authentication reliability.
2Area of stationary object
If relay service is provided to all terminals within range, then communication coverage is improved, but service security deteriorates
Solution Approach 1:
The patent applies local quality by providing relay service selectively to specific terminals identified as belonging to vehicle users, rather than uniformly to all terminals in range. This localized service provision maintains communication coverage for authorized users while preventing unauthorized access from outside the facility.
3Reliability
If identifier matching is performed for all communication terminals, then service security is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by having the reader detect and register terminal identifiers of vehicle users in advance. This pre-detection and registration process simplifies the authentication system by preparing authorized terminal lists beforehand, reducing the complexity of real-time identification while maintaining high service security.

AI summary
In a relay system, an authentication device determines whether a registered identifier of a registered terminal possessed by a user in a vehicle matches an identifier of a first communication terminal received from a relay base station via a base station, generates a permission signal indicating whether to permit relay of wireless communication between the first communication terminal and the base station, depending on the result of determination, and sends the generated permission signal to the relay base station via the base station. The relay base station relays wireless communication between the first communication terminal and the base station when the permission signal indicates that the relay of wireless communication is permitted. The relay base station omits to relay the wireless communication for the communication terminal when the permission signal indicates that the relay of wireless communication is not permitted.
