Mobile Device Power Control in Low Reception Areas

Solution Overview

Problem

Mobile communication devices face challenges in low reception areas, leading to increased power consumption and radiation exposure due to continuous search for signal, as they often boost transmission power without establishing a connection, which is inefficient and potentially harmful.

Innovation Solution

A system that includes a mobile communication device and a reception area server, which predict future locations and reduce transmission power in low reception areas by disabling the communication circuit when no connection is possible, and re-enable it when the device leaves the area, using location determination and reception data to manage power effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile communication device increases transmission power to improve connection chances in low reception areas, then the probability of establishing a connection is improved, but the power consumption of the battery increases and radiation exposure to the user increases

Engineering Contradiction:

Improveconnection establishment probabilityVSAvoidbattery power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by predicting future locations and determining reception conditions before the device actually enters low reception areas. The communication circuit is proactively disabled before the device enters areas where connection is impossible, preventing unnecessary power consumption and radiation exposure while maintaining connection reliability when possible

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from reception data and location information to dynamically control the communication circuit. The reception area server provides feedback about expected reception levels at predicted locations, and the mobile device adjusts its communication circuit operation based on this feedback, disabling the circuit when reception is predicted to be poor and enabling it when reception is expected to be good

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the mobile communication device continually searches for cellular towers in low reception areas, then the coverage search is maintained, but the power consumption increases unnecessarily

Engineering Contradiction:

Improvecoverage search capabilityVSAvoidbattery power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by predicting future locations and determining reception conditions before the device actually enters low reception areas. The communication circuit is proactively disabled before the device enters areas where connection is impossible, preventing unnecessary power consumption while maintaining the ability to search for coverage when appropriate

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the operation of the communication circuit based on real-time location and predicted reception conditions. Rather than continuously searching for coverage, the system adapts its behavior by enabling the communication circuit only when reception is expected to be sufficient and disabling it when reception is predicted to be poor, optimizing power consumption while maintaining coverage search capability

AI summary

Technologies for controlling mobile communication devices in a low reception area includes predicting a future location of the mobile communication device and determining reception data for the predicted future location. The reception data is indicative of an expected level of reception by the mobile communication device while in the future location. Transmission power of a communication circuit of the mobile communication device may be reduced in response to a determination that the expected level of reception is less than a reference threshold.
