Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for preventing communication connections in predefined areas, such as military zones or prisons, are inefficient in bounding the jamming area, impact unintended users, and violate health and regulatory constraints, particularly for uplink connections.
Innovation Solution
An apparatus and method that assess signal characteristics to determine admissibility, allowing for whitelisting or blacklisting user equipment, and transmit neutralization injection attacks to neutralize connections using synchronized, low-power signals, achieving precise area bounding and minimizing network disturbance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple jammers transmit pre-generated signals to prevent communication connections, then communication blocking is achieved, but area bounding precision deteriorates and unintended users are impacted
Solution Approach 1:
The system performs preliminary actions by establishing monitoring of signal characteristics before the neutralization decision is made. The apparatus continuously measures signal characteristics such as signal strength, timing, and frequency of communications within the predefined area, builds a profile of legitimate communication patterns, and only then decides whether to initiate neutralization injection attacks. This preliminary monitoring phase ensures that neutralization is applied selectively to actual threats while preserving legitimate communications, thereby improving area bounding precision without compromising communication blocking effectiveness.
2Reliability
If jammers transmit high-power signals to ensure strong jamming coverage, then communication blocking is effective, but health constraints and regulatory compliance deteriorate
Solution Approach 1:
The system applies partial action by using neutralization injection attacks that target only the specific communication protocols and messages required to block connections, rather than transmitting excessive high-power jamming signals across all frequencies. The apparatus injects targeted protocol-level attacks (such as fake base station messages, authentication rejection, or connection teardown packets) that neutralize communications with minimal power, well below health and regulatory thresholds, while maintaining effective communication blocking within the predefined area.
3Reliability
If Fake Base Stations transmit constantly to maintain connection establishment, then user equipment redirection is achieved, but area bounding precision and energy efficiency deteriorate
Solution Approach 1:
The system implements periodic action by having the Fake Base Station transmit broadcast messages and neutralization injections only at specific intervals and at critical moments in the connection establishment process, rather than continuously. The apparatus monitors for incoming connection requests from user equipment and triggers Fake Base Station responses only when needed to redirect or reject connections. This periodic operation maintains effective user equipment redirection while dramatically reducing energy consumption compared to constant transmission.
4Reliability
If Fine Tuning of transmitter power is applied to bound jamming area, then area bounding is achieved, but precision deteriorates due to imprecise power control
Solution Approach 1:
The system implements feedback by continuously measuring the signal characteristics of communications within the predefined area and using this information to adjust the neutralization injection attack parameters in real-time. The apparatus monitors signal strength, timing, and location of targeted communications, and dynamically adjusts the power and timing of Fake Base Station transmissions to maintain precise area bounding. This closed-loop feedback control compensates for imprecise power control capabilities and environmental variations, achieving accurate area bounding without requiring highly precise transmitter power control.
