Mobile Terminal Proximity Connection Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in connecting to wireless access points without pre-known SSID/Passkey, especially when the wireless direct function is not started, leading to connection errors and user confusion.
Innovation Solution
A mobile terminal with a processor and memory that acquires communication information from an external device using proximity wireless communication, attempting to connect and determining whether to prompt the user for a direct connection based on the acquired information, including the use of NFC or Bluetooth Low Energy for proximity communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal uses NFC touch to connect to the information processing device, then the connection process is simplified, but the user is not informed whether the wireless direct function started, leading to connection errors
Solution Approach 1:
The mobile terminal displays connection status information to the user after NFC touch, indicating whether the wireless direct function has started or not. This feedback mechanism resolves the contradiction by providing necessary information while maintaining the simplified NFC connection process.
Solution Approach 2:
The mobile terminal acts as an intermediary between the NFC touch operation and the actual connection establishment, checking the connection status and communicating it to the user. This intermediary role allows the system to maintain ease of operation while preventing information loss about connection status.
2Adaptability or versatility
If the information processing device operates by wired LAN connection without wireless direct function, then the SSID/Passkey are not included in the NFC tag, but only an IP address is stored, making wireless direct connection impossible
Solution Approach 1:
The mobile terminal checks the connection status of the information processing device before attempting wireless direct connection. By performing this preliminary check, the system can determine whether to proceed with wireless connection or inform the user of wired connection status, preventing failed connection attempts.
Solution Approach 2:
Instead of assuming wireless direct connection is always available, the system inverts the approach by first checking whether wireless direct function is actually started. This inversion prevents connection errors by adapting to the actual connection mode (wired or wireless) of the information processing device.
3Speed
If the mobile terminal attempts to connect without knowing the connection status, then the connection process is fast, but connection errors occur when the wireless direct function is not started
Solution Approach 1:
The mobile terminal performs a preliminary check of the information processing device's connection status before attempting wireless direct connection. This preliminary action adds minimal time but significantly improves connection reliability by preventing failed connection attempts when wireless direct function is not available.
Solution Approach 2:
The connection process becomes dynamic, adapting its behavior based on the detected connection status. The system can quickly proceed with wireless connection when available, or switch to informing the user about wired connection mode, thus maintaining speed while improving reliability.
Data Source
AI summary
A mobile terminal, which has acquired communication information from an external device, using proximity wireless communication attempts connection to the external device based on the acquired communication information. If the connection attempt to the external device fails, the mobile terminal determines whether to display a message prompting a user to use a direct connection function of the external device while displaying a message notifying failure of the connection attempt.
