Network Permissions Node for Wireless Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to enforce network access restrictions on wireless devices across different data networks, allowing unauthorized access to sensitive information when the device connects to uncontrolled access points.
Innovation Solution
Implementing a permissions node within the data network to manage and enforce access permissions for wireless devices, requesting and granting permission for connections to access points, and storing access permissions at both the network node and the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network access restrictions are imposed at the router, then data access of designated wireless devices can be restricted at the access point, but the wireless device will have unrestricted access when connecting to access points that do not impose restrictions
Solution Approach 1:
The patent introduces a permissions node as an intermediary between the wireless device and the access point. This permissions node maintains a database of authorized devices and communicates with both the access point and the wireless device to enforce access control policies. The permissions node acts as a mediator that enables restricted access while maintaining compatibility with multiple access points, resolving the contradiction between reliable access control and broad adaptability.
Solution Approach 2:
The patent moves the access control functionality from the traditional router dimension to a network-wide dimension by implementing a permissions node that operates at the network level rather than just at individual access points or devices. This dimensional shift allows centralized policy enforcement across multiple access points while maintaining device compatibility, solving the contradiction between control reliability and access point versatility.
2Reliability
If parental control software is installed on the wireless device, then data access can be restricted on the device itself, but restrictions cannot be enforced when the device connects to external access points
Solution Approach 1:
The permissions node serves as an intermediary that extends parental control functionality from the device level to the network level. Instead of relying solely on software installed on the wireless device, the permissions node intercepts and controls access requests at the network infrastructure level, ensuring that restrictions are enforced regardless of which access point the device connects to, while maintaining flexibility across different network environments.
Solution Approach 2:
The permissions node provides universal access control functionality that works across multiple network environments and access points. By implementing a centralized permission verification system that operates independently of device-specific software, the solution achieves both reliable data access restriction and broad network environment flexibility, allowing the same control mechanism to function whether the device is at home, at a friend's house, or in a public network.

AI summary
In systems and methods of controlling a connection between a wireless device and an access point, it is determined that a first wireless device is not authorized to connect to an access point of a first data network. A message is transferred to a second wireless device by a second data network requesting permission for the first wireless device to connect to the access point. A message can be received from the second wireless device granting the first wireless device permission to connect to the access point.
