IoT Wireless Device Reconnection Using Stable Service Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between IoT devices and remote computing devices is prone to failure due to changes in network names or passphrases, making it difficult for third-party operators to reconnect the IoT devices reliably.
Innovation Solution
A method and system for connecting IoT devices to wireless networks involving an access point that receives configuration information, including a service identifier and credential, and authenticates the device based on these, ensuring secure and reliable connectivity through a credential-based authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network authentication using network name and passphrase is used, then the IoT device can connect to the WLAN, but the connection reliability deteriorates when network parameters change
Solution Approach 1:
The patent introduces a service identifier as an intermediary element that mediates between the IoT device and the WLAN authentication process. Instead of directly using network name and passphrase, the service identifier acts as a stable reference that remains consistent even when network parameters change, enabling reliable reconnection without requiring manual reconfiguration
Solution Approach 2:
The patent changes the authentication parameter from volatile network-specific credentials (network name and passphrase) to a stable service identifier that is independent of network configuration changes. This parameter transformation allows the authentication mechanism to remain valid across network reconfigurations
2Adaptability or versatility
If network name or passphrase is changed, then security or configuration flexibility is improved, but the IoT device connection is disrupted requiring operator intervention
Solution Approach 1:
The service identifier serves as a mediator that decouples the IoT device from direct dependency on network name and passphrase. When network parameters change, the service identifier remains unchanged, allowing the device to automatically reconnect without operator intervention despite network reconfiguration
3Stability of the object's composition
If credential-based authentication with service identifier is implemented, then connection stability is improved, but the authentication system complexity increases
Solution Approach 1:
The service identifier is designed to be a universal authentication element that can be used across different WLAN configurations and scenarios. This multi-functionality allows a single simple identifier to replace complex network-specific credentials, maintaining connection stability without proportionally increasing system complexity

AI summary
Methods and systems for connecting a wireless device to a wireless network. Configuration information is received by an access point of the wireless network including a service identifier corresponding to a service provided through the wireless device and a credential associated with the wireless device. The access point advertises the service identifier to the wireless device. The access point receives from the wireless device an association request including a network identifier corresponding to the wireless network. The access point authenticates the wireless device based on the service identifier and the credential.
