Dynamic Access Point Connection Management for Wi-Fi Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current community Wi-Fi networks face limitations such as a maximum of five simultaneous connections and a shared bandwidth of 1 Mb/s, leading to saturated gateways that cannot accept new connections, and users lack certainty when connecting to alternative access points due to potential saturation.
Innovation Solution
A method where the first access point determines its resource availability and, if insufficient, requests resources from nearby access points, transferring the terminal connection to a second access point with available resources, using distinct connection identifiers for secure communication and resource reservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gateway uses a single community SSID to provide Wi-Fi access, then it can serve multiple visitors, but the number of simultaneous connections is limited to five and the bandwidth is shared at 1 Mb/s, leading to network saturation
Solution Approach 1:
The patent divides a single community SSID into multiple distinct SSIDs (first SSID, second SSID, third SSID) that can operate independently. Each SSID can accommodate separate connections, thereby increasing the total number of simultaneous connections beyond the five-connection limit of a single SSID while maintaining reliable access for each user group.
Solution Approach 2:
The gateway is configured to handle multiple SSIDs simultaneously, making it capable of serving different user groups (visitors, privileged users, domestic equipment) through a single device. This multi-functionality allows the gateway to manage diverse connection types and priority levels without requiring multiple physical access points.
2Adaptability or versatility
If a terminal connects to a saturated access point, then it can attempt to find an alternative access point, but there is no certainty that the connection will be effective and no message is provided to inform the user
Solution Approach 1:
The patent implements a feedback mechanism where the gateway actively informs the terminal about the availability status of alternative SSIDs. When the first SSID is saturated, the gateway provides information about the second SSID's capacity and status, enabling the terminal to make informed connection decisions rather than attempting connections blindly.
Solution Approach 2:
The terminal performs preliminary checks by querying the gateway about alternative SSID availability before attempting to connect. This preliminary action allows the terminal to identify suitable access points in advance, avoiding wasted connection attempts on saturated networks and reducing connection establishment time.
3Ease of operation
If access points use the same SSID identifier for communication, then it simplifies terminal connection, but it creates security risks and prevents dedicated communication channels between access points
Solution Approach 1:
The patent assigns different SSID identifiers to different communication purposes: the first SSID for public visitor access, the second SSID for privileged user access, and the third SSID for secure inter-access point communication. This local differentiation ensures that each communication channel has appropriate security characteristics while maintaining ease of connection for end users.

AI summary
The present invention relates to a method for connecting a terminal to a telecommunication network via an access point. In said method, after a request to connect a terminal (TER) to a first access point, the first access point (GW1) determines if it has access to a resource for serving the terminal and, if possible, serves the terminal. If not: the first access point (GW1) requests, from at least one second access point (GW2) to which it is connected, a resource for serving the terminal; and in the event that the resource is available to the second access point, the first access point transfers, to the terminal, data for enabling the terminal to connect to the second access point.
