Network Reconnection via NOC-Mediated Access Across Authentication Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices that do not support a target authentication mode, such as Matter protocol, often fail to reconnect to networks due to changes in network parameters during over-the-air updates, leading to disconnection issues.
Innovation Solution
A method and apparatus that utilize a first communication network supporting a target authentication mode to facilitate access to a second network by first indicating the second network to the device, enabling it to reconnect using node operational certificates (NOC) for improved connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices use traditional authentication modes for network connection, then initial connection can be established, but reconnection fails when network parameters change during over-the-air updates
Solution Approach 1:
The patent introduces a first communication network supporting target authentication mode as an intermediary channel. When devices fail to reconnect to the second network due to parameter changes, the system uses the first network as a backup pathway to deliver reconnection instructions and parameters, enabling successful reconnection without requiring the device to natively support the target authentication mode.
Solution Approach 2:
The patent changes the authentication parameter set by which network is used for communication. When reconnection to the original network fails, the system switches to use a different authentication mode on an alternative network, thereby adapting to the changed network conditions and enabling successful reconnection.
2Productivity
If network parameters are updated during over-the-air updates, then network functionality can be improved, but device reconnection stability deteriorates
Solution Approach 1:
The patent prepares a backup communication network (first network supporting target authentication mode) in advance before network parameter updates are applied. When updates cause reconnection failures, this pre-prepared alternative network serves as a cushion to maintain connectivity, preventing complete connection loss during the update process.
Solution Approach 2:
The system implements feedback by monitoring reconnection status after network parameter updates. When reconnection fails, the system detects this condition and triggers an alternative reconnection procedure through the first communication network, thereby adapting to the failed update scenario and restoring connectivity.
