Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile devices experience prolonged disconnection from wireless networks due to coverage gaps or obstructions, necessitating time-consuming full network scans to reconnect, which prolongs the disconnect time.

Innovation Solution

Devices employ a secondary communications protocol like Bluetooth Low Energy to broadcast a network request with parameters, receiving channel identifiers from nearby connected devices to prioritize channel scans, reducing the time needed to reconnect by focusing on relevant channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a full network scan is performed to reconnect to the network, then the device can find available base stations, but the reconnection time increases significantly

Engineering Contradiction:

Improvenetwork reconnection capabilityVSAvoiddisconnection duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by maintaining a history of previously scanned channels and base stations before disconnection occurs. When reconnection is needed, the device retrieves this pre-stored information rather than performing a complete scan, significantly reducing reconnection time while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network scan process is segmented into essential and non-essential parts. The system identifies and scans only the critical channels and base stations needed for reconnection, rather than performing a comprehensive full-spectrum scan, thereby reducing time loss while ensuring reliable network recovery

Inventive Principle:

Principle #1Segmentation

2Reliability

If a full network scan is performed to ensure reliable reconnection, then all available base stations can be identified, but the complexity of the reconnection process increases

Engineering Contradiction:

Improvenetwork reconnection capabilityVSAvoidreconnection process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts only the essential elements needed for reconnection from the complete network scan data - specifically the historical channel information and previously identified base stations. This extraction reduces process complexity by eliminating unnecessary scanning steps while preserving the core reconnection functionality

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An example computing device includes: a first communications interface configured to connect to a network using a first communications protocol; a second communications interface configured to communicate using a second communications protocol; a controller interconnected with the first and second communications interfaces, the controller configured to: in response to detecting a condition indicating the disconnect, broadcast, via the second communications interface, a network request including a network parameter for the network; receive, via the second communications interface, a channel identifier identifying a channel operating according the network parameter; initiate a channel scan on the channel and detect a base station operating on the channel; and control the first communications interface to connect to the base station.
