Solution Overview

Problem

Existing systems for preventing communication in predefined areas, such as military zones or government buildings, struggle with imprecise area bounding and impact on unintended users, particularly for uplink connections, and are difficult to implement without violating health and regulatory constraints.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple jammers transmit pre-generated signals to prevent communication in a predefined area, then communication blocking is achieved, but area bounding becomes imprecise and unintended users are affected

Engineering Contradiction:

Improvecommunication blocking effectivenessVSAvoidarea bounding precision

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by continuously monitoring signal characteristics (RSSI, TOA, TDOA, AoA) and pre-assessing connection admissibility before actual communication occurs. This allows the system to identify connections originating from within the predefined area in advance and neutralize them selectively, rather than using broad jamming that affects all users in the vicinity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention applies local quality by making the neutralization action targeted and location-specific. Using multiple receiving nodes to measure signal characteristics, the system determines the precise location of each connection and applies neutralization only to connections originating from within the predefined area, leaving connections from outside the area unaffected.

Inventive Principle:

Principle #3Local quality

2Reliability

If jammers transmit with high signal strength to ensure coverage of the predefined area, then communication blocking is effective, but health constraints and regulatory limits are violated

Engineering Contradiction:

Improvecommunication blocking effectivenessVSAvoidhealth and regulatory constraints

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts only the essential function of communication blocking while removing the harmful high-power transmission component. Instead of transmitting strong jamming signals, the system uses low-power receiving nodes to monitor connections and neutralizes only the specific connections originating from within the predefined area, dramatically reducing overall signal power requirements and eliminating health and regulatory concerns.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system introduces intermediary receiving nodes that act as mediators between the external environment and the protected area. These nodes monitor incoming connections, assess their admissibility based on measured signal characteristics, and trigger neutralization only when necessary, avoiding the need for high-power continuous transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If Fake Base Stations transmit broadcast messages continuously to attract user equipment, then connection establishment is prevented, but area bounding remains imprecise and power consumption is high

Engineering Contradiction:

Improveconnection establishment preventionVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The system employs periodic action by having receiving nodes monitor connections at regular intervals and assess admissibility continuously. The neutralization action is triggered periodically only when a connection from within the predefined area is detected, rather than continuous transmission, significantly reducing power consumption while maintaining effective connection prevention.

Inventive Principle:

Principle #19Periodic action

4Measurement precision

If transmitter power is fine-tuned to bound jamming to a specific area, then area precision is improved, but the system becomes complex and white spots or leakage occur

Engineering Contradiction:

Improvearea bounding precisionVSAvoidtransmitter power control complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The invention inverts the traditional approach by using receiving nodes instead of transmitting jammers. Rather than trying to precisely control transmission to bound the jamming area, the system receives signals from multiple nodes, measures their characteristics to determine connection origin, and neutralizes based on location assessment, simplifying the system while improving precision.

Inventive Principle:

Principle #13The other way round (Inversion)
