Smart Device Provisioning via Mobile Intermediary Bypassing AP Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of smart home devices becomes increasingly difficult as the number of devices grows, particularly when WIFI passwords are changed or network suppliers are altered, as existing one-click configuration methods fail when routers are in Access Point isolation mode, preventing effective provisioning of smart devices.
Innovation Solution
A method for provisioning smart devices that involves sending provisioning information from a client to a server and then wirelessly to the device, allowing connection establishment even when routers are in AP isolation mode, using techniques like Bluetooth or GPRS network transmission, and includes user selection and authentication processes to manage device provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If APP one-click configuration is used to send provisioning information through router broadcast, then smart device connection is simplified, but provisioning fails when router is in AP isolation mode
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the APP and the smart device. The mobile terminal receives provisioning information from the APP and wirelessly transmits it to the smart device, bypassing the router's AP isolation mode. This mediator enables the provisioning process to work around the network constraint imposed by the router.
Solution Approach 2:
The patent replaces the traditional network broadcast mechanism (relying on router-based LAN communication) with a wireless direct transmission mechanism. Instead of using the router's broadcast system, the mobile terminal uses wireless communication (such as Bluetooth or direct Wi-Fi) to send provisioning information, substituting the mechanical network infrastructure dependency with a more flexible wireless approach.
2Reliability
If wireless transmission is used to send provisioning information directly to smart device, then provisioning works in AP isolation mode, but additional wireless communication components are required
Solution Approach 1:
The mobile terminal is designed to perform multiple functions: it acts as the user's communication interface, receives provisioning information from the APP, and simultaneously serves as the wireless transmission device to the smart device. This multi-functionality reduces the need for dedicated provisioning hardware, as the mobile terminal already exists in the user's ecosystem and can handle the additional provisioning task without requiring separate specialized devices.
3Reliability
If device identifier verification is performed before provisioning, then unauthorized devices are blocked, but provisioning process becomes more complex
Solution Approach 1:
The patent performs device identifier verification as a preliminary action before the actual provisioning process begins. The mobile terminal checks whether the smart device's identifier is in the preset list before transmitting provisioning information. This preliminary verification step filters out unauthorized devices early in the process, preventing unnecessary provisioning attempts and simplifying the overall flow by avoiding complex verification steps during the provisioning itself.
Data Source
AI summary
The present disclosure relates to a method for provisioning of a smart device, system, and readable medium; in the present disclosure, a provisioning request used for obtaining provisioning information is sent to a server; in a case that the provisioning information returned by the server is received, then the provisioning information is sent to the smart device by a wireless means so that the smart device establishes a communications connection with the server according to the provisioning information; after obtaining the provisioning information from the server, the provisioning information is sent to the smart device by the wireless means; the smart device reuses the provisioning information to pass server authentication and establish the communications connection with the server.
