Smartcard Wireless Network Access via Terminal AP Mode Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartcard technologies face challenges in quickly and conveniently accessing wireless networks, leading to management issues when the smartcard cannot connect to a target router, with the reason for failure often unknown.
Innovation Solution
A method and system where a terminal or smartcard client acquires and notifies the smartcard of a wireless network's SSID and password, allowing it to connect and manage the smartcard based on connection results, including prompting users on connection situations, thus improving accessibility and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the smartcard automatically enters AP mode and provides a fixed SSID, then the smartcard can be easily found by mobile phones, but the management on the smartcard cannot be implemented if the smartcard cannot be found due to connection failures or other faults
Solution Approach 1:
The patent inverts the traditional connection initiation direction. Instead of the mobile phone searching for the smartcard in AP mode, the smartcard switches to STA mode and actively connects to the mobile phone's WIFI access point. This reversal allows the system to leverage the mobile phone's stronger processing and management capabilities while ensuring the smartcard can be reliably found and managed through the phone's WIFI scanning and connection management functions.
2Adaptability or versatility
If the smartcard switches to STA mode and connects to target router, then the smartcard can access wireless network, but the user cannot determine the true reason when connection fails
Solution Approach 1:
The patent implements a feedback mechanism where the smartcard detects the connection result and sends this information back to the terminal device. The terminal device then provides feedback to the user through the smartcard client, indicating whether the connection succeeded or failed. This closed-loop feedback system ensures that connection status information is not lost and users can understand the actual connection outcome.
3Adaptability or versatility
If the smartcard client sends SSID and password to smartcard, then the smartcard can connect to target router, but the operation on smartcard is not quick or convenient when connection fails
Solution Approach 1:
The patent applies preliminary action by having the terminal device proactively detect whether the smartcard is connected to the wireless network before user management operations are needed. The system pre-judges the connection status and prepares appropriate management actions, avoiding the need for users to manually check connection status or wait for connection failures to occur before taking action.

AI summary
The present invention provides a method for accessing a wireless network, where a terminal acquires an SSID (Service Set Identifier) and a password of the wireless network, controls a WIFI working mode of the terminal to be an AP (Access Point) mode, transmits an SSID signal of the terminal, detects a smartcard that accesses the terminal, and sends the SSID and password of the wireless network to the smartcard, so that the smartcard connects to the wireless network according to the received SSID and password of the wireless network and returns a connection result to the terminal. By using the method of the present invention, the smartcard can be managed according to a result of a connection success of the smartcard, and therefore, the management on the smartcard is quicker, more convenient, and more flexible, and manual input is avoided.
