Mobile Client Station Wi-Fi Access Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for establishing Internet access via wireless communication protocols in local computer networks from mobile client stations are not sufficiently fast, as they often require real-time data retrieval from a general database during the access request process, leading to optimized but slow Wi-Fi access.
Innovation Solution
The method involves pre-downloading connection information of access points into an on-board database of the mobile client station before the Internet access request, allowing the traversal and selection phases to occur independently of the general database, thereby accelerating the access process. Additionally, timeout parameters are reduced, and IP configuration phases are optimized to minimize delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time data retrieval from general database is performed during Internet access request, then data accuracy is ensured, but access duration increases to 9-14 seconds
Solution Approach 1:
The patent applies preliminary action by pre-downloading access point connection information into the mobile client station's embedded database before the Internet access request occurs. This allows the system to have data ready in advance, eliminating the need for real-time database retrieval during the access request process, thereby reducing access duration from 9-14 seconds to less than 1.5 seconds while maintaining data accuracy.
2Speed
If connection information is pre-downloaded into embedded database, then access speed increases to less than 1.5 seconds, but device complexity increases due to additional database management
Solution Approach 1:
The patent applies the copying principle by creating a local embedded database that contains copies of access point connection information from the general database. This local copy enables fast access operations without requiring complex real-time interactions with the remote general database, thus achieving high access speed while keeping the added complexity manageable through simple local storage and retrieval operations.
3Loss of time
If timeout parameters are reduced and IP configuration is optimized, then access duration decreases to less than 1.5 seconds, but reliability may be compromised due to reduced time for error handling
Solution Approach 1:
The patent applies preliminary action by pre-configuring timeout parameters and IP configuration settings before the access request process begins. By having these parameters predetermined and optimized, the system can execute the access process quickly (less than 1.5 seconds) while maintaining reliable error handling, as the time parameters are already set to appropriate values that balance speed and reliability requirements.

AI summary
This method of establishing Internet access by using a WLAN protocol from a mobile client station, by way of an access point to be chosen from a set of identified access points, comprises the following steps: providing (100) a general database (14) of the access points identified with connection information; requesting (104) Internet access by using said protocol by carrying out in succession phases of scanning (106), selection (108), association (110), authentication (112) and configuration (114); establishing (124) Internet access from the mobile client station by way of the selected access point. Prior to and independently of the step (104) of requesting Internet access, information regarding connection of at least part of the access points of the general database (14) is downloaded (102) into an on-board database (24) of the mobile client station. Moreover, the scanning (106) and selection (108) phases are carried out on the basis of the downloaded connection information, without invoking the general database (14) and the access points identified.
