Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face inefficiencies in managing power consumption when experiencing radio-link outages in reduced performance environments, such as movie theaters or basements, due to continuous and fruitless attempts to reestablish network connections, leading to battery depletion and heat issues.
Innovation Solution
Mobile devices collect and share radio-link performance data with a centralized server to create a network reconnection schedule based on crowd-sourced information, adjusting reconnection attempts frequency and timing to conserve energy and avoid unnecessary battery drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices continuously scan for network connections in open-loop fashion, then network reconnection reliability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The system performs preliminary actions by collecting network outage data from multiple devices in advance, analyzing patterns, and creating predictive models before individual devices need to reconnect. This allows devices to make informed decisions about when to attempt reconnection based on predicted network availability rather than continuously scanning.
Solution Approach 2:
The system implements feedback mechanisms by continuously collecting network connection data from mobile devices, analyzing this data to identify patterns and predict outages, then using these predictions to adjust reconnection strategies. This closed-loop feedback system enables dynamic optimization of reconnection timing based on actual network behavior patterns.
2Speed
If mobile devices continuously scan for network connections, then network reconnection speed is improved, but heat generation increases
Solution Approach 1:
The system performs preliminary analysis of network outage patterns using crowd-sourced data before devices experience outages. By predicting when networks will be unavailable, the system prevents devices from attempting reconnections during known outage periods, eliminating unnecessary processing and heat generation while maintaining quick reconnection when networks are actually available.
3Reliability
If mobile devices attempt frequent reconnection in reduced performance environments, then network availability is improved, but energy waste increases
Solution Approach 1:
The system uses feedback from crowd-sourced network outage data to dynamically adjust reconnection strategies. By analyzing patterns from multiple devices and locations, the system provides feedback that enables individual devices to skip reconnection attempts during predicted outages, eliminating energy waste on futile attempts while maintaining network availability when connections are actually possible.
Solution Approach 2:
The system changes the parameter of reconnection timing from fixed intervals to dynamically adjusted timing based on predicted network availability. By modifying when reconnection attempts occur based on analyzed patterns rather than using constant scanning intervals, the system eliminates energy waste during guaranteed outages while maintaining network availability when networks are operational.

AI summary
In a first embodiment, a method includes: entering a reduced communications performance environment, wherein a mobile device connected to a network loses connection to the network; attempting to reconnect to the network in the reduced performance environment without success; recording network connection attempt information; entering an improved performance environment, wherein the mobile device is reconnected to the network; and transmitting the network connection attempt information to a remote server. In a second embodiment, a method includes: consulting a network reconnection attempts profile previously sent from a cloud server to a mobile device; based on the network reconnections attempts profile, determining a network reconnection attempt schedule; and attempting to reconnect to the network according to the network reconnection attempt schedule until the mobile device is reconnected to the network.
