Solution Overview

Problem

Modern mobile devices independently manage performance and power settings based on local conditions, leading to sub-optimal power efficiency and reduced battery life due to inefficient scanning of wireless channels.

Innovation Solution

A collaborative operational management system that accumulates sensor-based information from multiple mobile devices, identifies global context information, and sends operational recommendations to individual devices for optimized power and performance settings, eliminating the need for continuous scanning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mobile devices independently scan wireless channels to determine Internet connection availability, then devices can autonomously manage their own connections, but power efficiency deteriorates and battery life reduces

Engineering Contradiction:
Improveautonomous connection managementVSAvoidpower efficiency
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple mobile devices' sensor data and sends it to a cloud server for centralized processing. Instead of each device independently scanning wireless channels, the system merges their information and processes it collectively, reducing redundant scanning operations and power consumption while maintaining autonomous connection management capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cloud server acts as an intermediary between mobile devices and wireless networks. The server receives sensor data from devices, determines Internet connection availability centrally, and provides recommendations to devices. This intermediary approach eliminates the need for each device to perform energy-consuming independent scanning while preserving autonomous operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If mobile devices perform continuous wireless channel scanning to maintain connection availability, then connection reliability improves, but battery life deteriorates

Engineering Contradiction:
Improveconnection availabilityVSAvoidbattery life
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The system performs preliminary wireless channel assessment by collecting sensor data from multiple devices and processing it in advance on the cloud server. The server determines connection availability before devices need to scan, providing proactive recommendations that ensure connection reliability without requiring continuous device-side scanning that would drain battery life.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism where mobile devices send sensor data to the cloud server, which analyzes the information and returns connection recommendations. This feedback loop maintains connection availability by providing up-to-date recommendations based on aggregated data from multiple devices, reducing the need for frequent continuous scanning and preserving battery life.

Inventive Principle:
Principle #23Feedback

AI summary

Methods and systems may provide for accumulating sensor-based information from a plurality of mobile devices and identifying context information in the sensor-based information, wherein the context information is relevant to a particular mobile device in the plurality of mobile devices. Additionally, an operational recommendation may be sent to the particular mobile device based on the context information. In one example, the operational recommendation identifies one or more of a power management action, a performance management action, a wireless interface selection and a wireless access point selection.
