Intelligent Network Access Controller for Selective Wireless Device Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless access restriction solutions lack the ability to selectively control access across various wireless technologies and spectrums, often imposing total prohibitions that are complex, expensive, and do not allow for device-specific access, making them inadequate for situations requiring targeted access, especially in localized areas or for specific user groups.
Innovation Solution
An intelligent network access controller that classifies wireless devices into categories and selectively allows or blocks access based on their identity, using a combination of modules for identification, access determination, and locking, allowing for controlled access across multiple wireless technologies and spectrums within a defined geographical area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If total wireless access prohibition is implemented in targeted areas, then security is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements differential access control where different devices receive different treatment within the same geographical area. The access level determination module classifies devices into multiple categories (e.g., emergency services, authorized users, general public) and applies specific access rules to each category rather than implementing a blanket prohibition, thereby maintaining security while reducing system complexity.
Solution Approach 2:
The access control system segments the wireless device population into distinct categories based on device identity and access levels. By dividing devices into groups with different access permissions rather than treating all devices uniformly, the system achieves targeted security control with reduced complexity compared to total prohibition approaches.
2Reliability
If blanket access restriction is applied to all devices in an area, then security is improved, but adaptability decreases
Solution Approach 1:
The system assigns different access levels to different devices based on their identity and characteristics. Each device category receives tailored access permissions appropriate to its function and security requirements, allowing the system to adapt to diverse device types while maintaining overall security through differentiated control policies.
3Reliability
If additional communication systems are deployed for access control, then access control capability is improved, but device complexity and cost increase
Solution Approach 1:
The access control system utilizes existing wireless communication infrastructure to perform multiple functions: normal communication, device identification, and access control enforcement. By making the existing communication system multi-functional rather than deploying separate dedicated access control infrastructure, the system achieves robust access control capability while avoiding additional system complexity.
Solution Approach 2:
The access level determination module acts as an intermediary that processes device identities and decides access permissions using existing communication channels. This mediator approach enables access control functionality to be integrated into the existing communication system rather than requiring separate infrastructure.

AI summary
A method for controlling access to wireless communications includes generating an overlay to a portion of an existing wireless network by controlling radio frequency (RF) equipment to establish a defined geographical volume as the overlay; receiving an indication of wireless devices within the volume, the indication including three-dimensional positions of the wireless devices within the boundary; establishing identities for the wireless devices, the identities selected from the group consisting of allowed, unknown, and restricted; generating a private network encompassing at least a portion of the volume; locking and maintaining locked unknown and restricted wireless devices to the processor; and directing allowed wireless devices to access the private network for wireless communications within the volume.
