Solution Overview

Problem

Existing systems for managing access to mobile communications networks in specific areas, such as stadiums or airports, are costly and inconvenient due to the need for multiple transceivers to operate in various frequency bands, and UEs may enter a 'perfect cell' mode, avoiding measurements of neighboring cells.

Innovation Solution

A simplified configuration using downlink-only transmitters to interfere with broadcast control signals on non-target carriers, ensuring UEs camp on a specific cell by transmitting interference signals on necessary carriers, while maintaining a minimal number of transceivers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple transceivers are deployed to operate in all relevant frequency bands to capture all UEs, then network access management capability is improved, but system cost and deployment complexity increase

Engineering Contradiction:

Improvenetwork access management capabilityVSAvoidtransceiver configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the frequency band coverage function by separating transceivers (handling only necessary frequency bands) from transmitters (providing interference on other bands). This allows the transceiver configuration to be minimal while still achieving comprehensive frequency band management through coordinated transmission.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transmitter component is designed with multi-functionality, serving both as an interference source to prevent UE camping on unauthorized cells and as a signal source for UEs that need to camp on the target cell. This universal component replaces the need for multiple specialized transceivers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If transceivers operate in all relevant frequency bands to ensure UE capture, then coverage completeness is improved, but deployment cost increases

Engineering Contradiction:

ImproveUE capture reliabilityVSAvoidtransceiver quantity

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system divides the frequency band management into two segments: transceivers handle only the essential frequency bands needed for normal operation, while transmitters provide supplementary coverage and interference management on other frequency bands, reducing the total number of transceivers required.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transmitter acts as an intermediary component that bridges the gap between limited transceiver frequency band coverage and comprehensive UE capture requirements. By providing interference signals and alternative signal sources, it enables reliable UE capture across all frequency bands without requiring transceivers on every band.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If downlink signal power is increased to force UE reselection, then cell reselection effectiveness is improved, but energy consumption increases

Engineering Contradiction:

Improvecell reselection effectivenessVSAvoidtransmitter energy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system converts the potentially harmful effect of continuous high-power transmission into a beneficial intermittent operation. Transmitters operate only when needed to facilitate cell reselection or provide interference, rather than continuously transmitting at high power, thereby reducing energy consumption while maintaining reselection effectiveness.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

Instead of continuous high-power transmission, the system uses periodic or event-triggered transmission from the transmitters. Transmission occurs only when cell reselection is needed or when interference is required to prevent unauthorized camping, reducing overall energy consumption while maintaining productivity.

Inventive Principle:

Principle #19Periodic action
