Proximity Sensor Access Control for Radio Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing authorized MAC addresses for access to a radio access network is complex, often requiring administrator intervention and can lead to security issues due to the need for manual configuration and potential unauthorized access.
Innovation Solution
A method and device for controlling access to a radio access network that detects user presence using a proximity sensor, allowing automatic authorization of devices with valid MAC addresses without administrator intervention, simplifying access management and enhancing security by conditioning network identifier broadcast on user presence and managing access lists dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MAC address filtering is implemented to enhance security, then network security is improved, but device complexity and ease of operation deteriorate due to manual configuration requirements
Solution Approach 1:
The system automatically detects user presence via proximity sensor and autonomously adds devices to the authorized MAC address list without requiring administrator intervention. The access device self-manages the authorization process by detecting when a user approaches and automatically permitting their device to connect, eliminating the need for manual MAC address configuration while maintaining security.
Solution Approach 2:
The system performs preliminary detection of user presence through proximity sensing before the actual connection request occurs. By detecting the user's approach in advance, the system prepares the authorization state beforehand, so when the device attempts to connect, the MAC address is already authorized, streamlining the entire access process.
2Reliability
If MAC address filtering is implemented to control access, then unauthorized access is prevented, but administrator intervention is required increasing operational complexity
Solution Approach 1:
The access device automatically manages its own authorization list by detecting user presence and autonomously adding corresponding devices to the authorized MAC address list. This self-service mechanism eliminates the need for administrator configuration while maintaining strict access control, reducing device complexity significantly.
Solution Approach 2:
The manual mechanical process of administrators configuring MAC addresses is replaced by an automated sensing and detection system. The proximity sensor and automatic authorization logic substitute for the manual configuration process, maintaining access control reliability while eliminating the complexity of configuration management.
3Reliability
If manual MAC address configuration is required, then security is maintained through controlled access, but ease of operation deteriorates due to complex setup procedures
Solution Approach 1:
The system performs automatic device setup by detecting user presence and automatically adding devices to the authorized list without requiring administrators to manually input MAC addresses. This self-service approach maintains security through controlled MAC address filtering while making device setup trivial for users.
Solution Approach 2:
The system performs preliminary detection and authorization preparation before the user needs to connect their device. By detecting presence in advance and pre-authorizing the device, the system eliminates complex setup procedures while maintaining security, as the authorization is already in place when the user attempts to connect.
Data Source
AI summary
A technique for controlling access to a radio access network administered by an access device. The device obtains an item of data indicating that the presence of a user has been detected in a detection zone. An access request requesting access to the radio access network is received from an applicant device, the radio access network being prohibited by the access device for a device with physical address corresponding to that of the applicant device. The applicant device, identified by the address, is then authorized by the access device to access the radio access network.
