Server Filtering Wi-Fi Access Points by User Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when searching for accessible Wi-Fi access points (APs) as they are often presented with unnecessary AP information, including those from different communications companies or with varying communication rates, making it difficult to connect to the optimal AP.
Innovation Solution
A server and user terminal system that acquires and analyzes wireless communication connection information and zone data to determine and provide the optimum AP based on the user's communications company and average communication rate, ensuring efficient connection by filtering and prioritizing APs according to user-specific criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all APs within predetermined distance are provided in the list, then the user terminal can find APs, but unnecessary AP information is provided causing user inconvenience
Solution Approach 1:
The server extracts and provides only the necessary AP information (compatible APs with good communication rates) from the complete list of all APs within range. This filtering process removes unnecessary AP information while preserving useful connections, directly resolving the contradiction between providing comprehensive AP lists and avoiding unnecessary information.
Solution Approach 2:
The patent applies different quality criteria to different APs in the list based on their compatibility with the user terminal's communications company and communication performance. Rather than treating all APs uniformly, the system identifies and highlights APs with superior local qualities (compatibility and communication rate) to guide user selection.
2Adaptability or versatility
If AP information from different communications companies is included, then more AP options are available, but user compatibility is reduced
Solution Approach 1:
The server extracts AP information based on compatibility criteria, separating compatible APs (same communications company or high communication rate) from incompatible ones. This extraction process maintains adaptability by including multiple AP options while ensuring reliability by filtering for compatibility, preventing user confusion about which APs to connect to.
3Area of stationary object
If AP list includes all available APs, then coverage is complete, but user decision time increases
Solution Approach 1:
The server extracts and prioritizes the most suitable APs (those with highest communication rates and compatibility) from the complete coverage list. This allows the system to maintain comprehensive AP coverage information while significantly reducing user decision time by highlighting optimal choices, so users don't need to evaluate every AP in the list.
Solution Approach 2:
The server performs preliminary analysis and ranking of APs based on communication rates and compatibility before presenting the list to the user. This preliminary action of pre-evaluating and ordering APs saves user time during the selection process while maintaining complete coverage information for reference.

AI summary
Provided is a control method of a server providing information on an optimum AP. The control method of a server includes: acquiring wireless communication connection information of at least one user terminal and location information of the at least one user terminal, from each of the at least one user terminal; when a request for an access point (AP) search is received from a first user terminal, determining at least one optimum AP which can connect with the first user terminal, on the basis of the acquired wireless communication connection information and location information; and transmitting information on the determined optimum AP to the first user terminal.
