Intelligent Network Access Controller for Selective Wireless Device Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication access restriction solutions, such as jamming and cell shutdown, are ineffective as they do not discriminate among users, are complex and expensive to implement, and prevent all wireless communications, including those necessary for emergency responses.
Innovation Solution
An intelligent network access controller (INAC) that dynamically controls access to a macro wireless network by registering and classifying wireless devices, determining their characteristics, and granting or blocking access based on these characteristics, thereby creating a local wireless network for restricted access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless access restriction methods (jamming, cell shutdown) are used, then unauthorized access is blocked, but all wireless communications including emergency responses are also prevented and the system becomes complex and expensive
Solution Approach 1:
The patent segments the wireless device population into distinct categories (authorized, unauthorized, emergency) and applies different access control rules to each segment. The INAC evaluates device characteristics and dynamically assigns devices to appropriate access categories, enabling differentiated control rather than blanket restriction.
Solution Approach 2:
The INAC acts as an intermediary layer between wireless devices and the macro wireless network. It intercepts access requests, evaluates device characteristics against stored criteria, and makes intelligent routing decisions - allowing authorized devices through while blocking unauthorized ones, and specially handling emergency communications.
2Reliability
If traditional wireless access restriction methods are used, then unauthorized access is blocked, but emergency communications are also prevented
Solution Approach 1:
The system dynamically adjusts access control decisions based on real-time evaluation of device characteristics. The INAC continuously monitors device properties and changes access permissions accordingly, rather than using static blocking rules. This enables the system to adapt to different situations including emergency communications.
Solution Approach 2:
The INAC implements feedback mechanisms where device responses and communication patterns are evaluated to determine access permissions. The system learns from communication outcomes and adjusts its access control decisions, enabling it to recognize and prioritize emergency communications while maintaining security.
3Adaptability or versatility
If dynamic device classification and characteristic determination are implemented, then selective access control is achieved, but processing complexity and time increase
Solution Approach 1:
The system performs preliminary actions by pre-storing device characteristic criteria and access rules in the INAC before actual access requests occur. Device characteristics to be evaluated and the corresponding access decisions are prepared in advance, enabling rapid processing when devices actually attempt to connect.
Solution Approach 2:
The patent replaces complex mechanical evaluation processes with automated electronic characteristic analysis. The INAC uses electronic comparison of device properties against stored criteria, substituting manual or complex processing with efficient electronic evaluation that rapidly determines access permissions.

AI summary
A method for managing wireless device communications includes establishing active, persistent, and repetitive communications with a wireless device operating in a coverage area of a local wireless network. In an example, the local wireless network is an overlay to a portion of a macro wireless network. The repetitive communications include placing a call to the wireless device, completing a call connection to the wireless device, sending a message to the wireless device, receiving and processing a response to the message from the wireless device, and persistently repeating a call function of the placing a call, completing a connection, sending a response, and receiving and processing the response until a specified termination event. In an example, the termination event is a power off of the wireless device.
