Terminal Device Tethering to WLAN Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in promptly switching from tethering to WLAN communication due to limited WLAN coverage and lower communication speeds, increased radio resource consumption, and power consumption, as well as difficulties in selecting the most desirable WLAN connection from multiple available options.
Innovation Solution
A mobile communication terminal device that selects and connects to the most desirable WLAN by acquiring and analyzing network information, use situation, and disposition situation data from a network information providing device, allowing for efficient switching from tethering to WLAN communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the apparatus attempts to connect to various WLANs to switch from tethering, then communication switching is enabled, but connection time becomes long and switching cannot be prompt
Solution Approach 1:
The patent applies preliminary action by having the apparatus store connection information (SSIDs, passwords, and connection status) of WLANs in advance before switching is needed. When tethering communication is established, the apparatus automatically switches to a stored WLAN without performing real-time connection attempts, thereby reducing connection time and enabling prompt communication switching.
2Measurement precision
If the user manually selects a WLAN to switch from tethering, then connection accuracy is improved, but operation complexity increases and switching cannot be prompt
Solution Approach 1:
The patent applies self-service by enabling the apparatus to automatically select and switch to a WLAN based on stored connection information without requiring manual user input. The apparatus autonomously determines which WLAN to connect to using pre-stored SSID and password information, thereby maintaining selection accuracy while simplifying operation and enabling prompt switching.
3Area of stationary object
If tethering communication is used to extend WLAN coverage area, then communication area is expanded, but communication speed decreases and power consumption increases
Solution Approach 1:
The patent applies dynamics by enabling the apparatus to dynamically switch between tethering communication and WLAN communication based on real-time communication needs and environmental conditions. When a WLAN is available and suitable, the apparatus switches to WLAN communication to achieve higher speeds and lower power consumption, while using tethering only when necessary to extend coverage, thereby optimizing both communication area and performance.
