Intelligent Network Access Controller Selective Wireless Device Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication access restriction solutions, such as jamming and cell shutdown, are ineffective in selectively limiting access to specific users within a localized area, as they either block all wireless communications or require establishing a secondary network, and fail to discriminate among users.
Innovation Solution
An intelligent network access controller (INAC) dynamically controls access by registering and classifying wireless devices, determining their characteristics, and either locking them to a local network or allowing access to a macro network based on these characteristics, enabling selective and targeted access restrictions across various wireless technologies and frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If jamming equipment is used to block wireless signals in a particular area, then wireless access restriction is achieved, but all wireless communications are prohibited including emergency personnel communications
Solution Approach 1:
The system applies different access control properties to different wireless devices within the same geographic area. Authorized devices (police, fire, emergency personnel) are granted access while unauthorized devices are blocked, creating localized quality differences in access permissions rather than uniform blocking
Solution Approach 2:
The wireless device population is segmented into authorized and unauthorized categories based on device identification and classification. The access control system processes different device segments differently, allowing selective restriction rather than blanket blocking
2Reliability
If cell shutdown is used to restrict wireless access, then access control is achieved, but a secondary network must be established and the solution is complicated and expensive
Solution Approach 1:
The access control system acts as an intermediary layer between wireless devices and the macro network. It intercepts device registrations, classifies devices, and dynamically controls access without requiring complete network shutdown or secondary network establishment
Solution Approach 2:
The system provides multiple functions within a single platform: device registration, classification, dynamic access control, and emergency communication support. This multi-functionality eliminates the need for separate jamming equipment and secondary networks
3Adaptability or versatility
If dynamic device classification and selective access control are implemented, then selective access restriction is achieved, but system complexity increases
Solution Approach 1:
Wireless devices are pre-classified into authorized and unauthorized categories during the registration process. This preliminary classification enables automatic access decisions without requiring complex real-time analysis, reducing operational complexity
Solution Approach 2:
The system continuously monitors device locations and dynamically adjusts access control based on real-time conditions. Devices are tracked as they enter and exit controlled areas, with automatic access granting or blocking based on their classification and current location

AI summary
An intelligent network access controller for use with a wireless network that provides communications services to subscribers having wireless communications devices includes a multi-protocol interface for receiving and sending digital messaging by the wireless communications devices; an identification module that determines an identity of a wireless communications device; an access module that receives the identity and determines an access level for the wireless communications device; and a locking module that locks selected wireless communications devices to the controller based on the determined access level.
