Portable Terminal WLAN Link Setup via Server Push
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for establishing a wireless local area network (WLAN) link between portable terminals are cumbersome and time-consuming, particularly when multiple devices need to be connected, due to complex settings and potential user errors in configuring security connections.
Innovation Solution
A method and apparatus that allow portable terminals to quickly and conveniently connect by displaying a contact list, transmitting connection information including SSID, channel number, and security key over a mobile communication network, and establishing a WLAN link based on ad hoc or infrastructure mode, with the option to execute specific applications, using a push mechanism to simplify the setup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually configure security connections and search for buttons through setting menus, then connection security can be established, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent introduces an intermediary server that automatically generates and distributes connection information to portable terminals. Instead of users manually configuring security settings or searching for buttons through complex menus, the server acts as a mediator that handles the configuration process, thereby simplifying user operations while maintaining connection security through automated authentication mechanisms.
Solution Approach 2:
The system enables self-service by allowing portable terminals to automatically receive and execute connection information without requiring user intervention in the configuration process. The terminals autonomously handle the connection setup through the server, eliminating the need for users to navigate complex setting menus or manually input security parameters.
2Reliability
If users manually set all devices connected to WLAN, then proper security connection is achieved, but the process becomes very cumbersome and time-consuming
Solution Approach 1:
The server performs preliminary actions by pre-generating and storing connection information before the actual connection process. When a portable terminal needs to connect, the required security parameters and configuration data are already prepared and can be immediately retrieved and applied, eliminating the need for time-consuming manual setup of each device.
Solution Approach 2:
The server serves as an intermediary that manages the connection information distribution to multiple portable terminals simultaneously. This mediator approach allows secure connection setup across multiple devices without requiring users to manually configure each one individually, thereby reducing overall setup time while maintaining security through centralized authentication.
3Ease of operation
If PBC button is implemented in hardware way, then connection can be initiated, but device may malfunction due to user confusion with other buttons
Solution Approach 1:
The patent eliminates the need for physical PBC buttons by introducing a server as an intermediary that handles connection initiation remotely. Instead of relying on hardware buttons that users might confuse with other buttons (causing malfunctions), the system uses server-mediated connection requests that are clearly identified and cannot be accidentally triggered, thereby improving both ease of operation and device reliability.

AI summary
A method of connecting a plurality of portable terminal over a wireless local area network (WLAN), the method including: a user selecting at least one contact from a contact list displayed on a screen of a first portable terminal, transmitting, from the first portable terminal to an external server over a cellular network, connection information necessary for establishing a WLAN link to the first portable terminal; pushing the connection information from the external server to a second portable terminal corresponding to the selected contact; a user pressing a connection authentication button on a selection menu displayed on the second portable terminal, and establishing the WLAN link to the first portable terminal from the second portable terminal by using the connection information.
