Router Pushing Credentials to Devices for Fast Networking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing HiLink connection protocol for networking devices is inefficient and unreliable, requiring multiple WiFi connections and depending on the stability of the router-terminal device connection, leading to long addition times and frequent connection failures.
Innovation Solution
The method eliminates the need for WiFi reconnection by directly sending a message from the primary router to the device to be added, allowing it to connect proactively, using encrypted SSID and password information via probe request or beacon frames, simplifying the networking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile phone performs WiFi reconnection to re-obtain the WiFi connection, then the user does not sense disconnection and reconnection, but the networking process takes a long time and has low reliability
Solution Approach 1:
The patent extracts and removes the WiFi reconnection step from the device addition process. Instead of requiring the mobile phone to disconnect from and reconnect to the router, the system directly establishes communication between the router and the to-be-added device through alternative messaging channels (probe requests, beacon frames, or direct device-to-device communication), eliminating the time-consuming and unreliable reconnection operation while maintaining network connectivity for the user.
Solution Approach 2:
The patent implements preliminary action by having the router send the SSID and password information to the to-be-added device in advance, before the mobile phone needs to reconnect. The router proactively pushes the networking information to the target device, allowing the device to prepare for connection beforehand, thus avoiding the need for repeated connection attempts and reducing both time and reliability issues.
2Ease of operation
If the mobile phone automatically reconnects to the primary router, then the WiFi connection is maintained, but the process is error-prone and depends on connection stability
Solution Approach 1:
The patent introduces an intermediary mechanism where the router acts as a mediator to transmit networking information to the to-be-added device. Instead of relying on the mobile phone to manually manage disconnection and reconnection cycles, the router pushes the necessary SSID and password information directly to the target device, which then autonomously connects to the network. This eliminates the error-prone reconnection process while maintaining ease of operation.
Solution Approach 2:
The patent enables self-service by allowing the to-be-added device to autonomously obtain networking information and connect to the primary router without requiring the mobile phone to repeatedly establish and break connections. The device automatically receives the pushed SSID and password information and performs its own connection, reducing dependency on mobile phone connection stability and manual reconnection operations.
3Productivity
If the device adds networking information and requires WiFi reconnection, then the device can join the network, but the process becomes complex and time-consuming
Solution Approach 1:
The patent extracts and removes the complex WiFi reconnection sequence from the device addition process. By eliminating the requirement for the mobile phone to disconnect and reconnect to the router, the process is simplified to: mobile phone connects to router once → router receives networking information request → router pushes SSID and password to to-be-added device → device connects to network. This reduces both the time required and the operational complexity while maintaining successful device addition.
Solution Approach 2:
The patent applies preliminary action by having the router prepare and push the SSID and password information to the to-be-added device before the actual connection is needed. This pre-delivery of networking information eliminates the need for subsequent reconnection operations, streamlining the entire device addition process and improving productivity without adding complexity.

AI summary
The present invention provides a method for networking between devices, including: connecting to, by a user mobile phone C, a primary router A, and detecting a nearby device B that can be networked; tapping, by a user on the user mobile phone C, a button for adding the device B, to send information about the to-be-added device B (for example, an SSID of the device B) to the primary router A; after receiving a message sent by the mobile phone C, obtaining, by the primary router A, the SSID of the to-be-added device B, and sending a notification message to the SSID (the message needs to include an SSID and a password of the router A that need to be encrypted) to instruct B to connect to the primary router A (the primary router A); and after receiving the SSID and the password of the primary router A, connecting to, by the device B, the primary router A, so that the device is added.
