Terminal Device Pre-Authentication for WLAN Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication via WLAN is limited to specific areas and tethering can result in low communication speeds due to mobile network conditions, leading to increased radio resource consumption and power usage, with a lengthy delay before switching to WLAN communication, especially when user authentication is required.
Innovation Solution
A terminal device acquires and executes authentication information from another mobile communication terminal to expedite the authentication process for connecting to a wireless network, reducing the time before wireless communication starts by pre-acquiring authentication information such as subscriber identity module data or generated information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus connects to a new access point and performs user authentication by inputting a password, then authentication security is improved, but the time required before communication by way of WLAN starts increases
Solution Approach 1:
The invention performs preliminary authentication actions by acquiring authentication information from a mobile communication terminal before the WLAN authentication process begins. This allows the terminal device to have authentication credentials ready in advance, significantly reducing the time required to establish WLAN communication while maintaining security through proper authentication protocols
2Area of stationary object
If the apparatus uses tethering through a mobile communication terminal, then communication area coverage is improved, but communication speed decreases and power consumption increases
Solution Approach 1:
The invention dynamically switches between tethering mode and WLAN communication mode based on availability and performance conditions. When WLAN access points are detected and authentication is successful, the system transitions from mobile network tethering to WLAN communication, optimizing both speed and power consumption while maintaining broad coverage capability
3Productivity
If the apparatus switches from tethering to WLAN communication, then communication speed and power efficiency are improved, but the switching delay increases
Solution Approach 1:
The system performs preliminary actions by acquiring authentication information from the mobile communication terminal before the actual WLAN connection is established. This pre-acquisition of credentials enables faster switching to WLAN communication when access points become available, reducing the delay between detecting WLAN availability and establishing communication

AI summary
[Object] To enable a time before communication by way of a wireless network starts to be further reduced.[Solution] Provided is a terminal device including: an acquisition unit configured to acquire authentication information provided by another terminal device configured to perform mobile communication in a mobile communication network; and an authentication execution unit configured to perform an authentication procedure for connecting to a wireless network different from the mobile communication network by using the authentication information. The authentication information includes information provided by a subscriber identity module of the other terminal device or information generated based on the information. The acquisition unit acquires at least some of the authentication information before the authentication procedure starts.
