Access Point Device BSS Selection via Association Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi network technologies lack efficient mechanisms for interoperable use of frequency bands and channels, particularly in scenarios where the association and authentication status of wireless devices are not adequately considered, leading to suboptimal BSS selection and network resource allocation.
Innovation Solution
The implementation of an access point device and server communication protocol that differentiates between associated and unassociated wireless devices by including an indication of device state in forwarding messages, allowing the server to provide tailored BSS candidate lists based on device authentication and network load balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the access point device treats all wireless devices uniformly without considering association status, then the protocol simplicity is maintained, but the network resource allocation efficiency deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the treatment of wireless devices based on their association status with the access point. Associated devices receive prioritized BSS candidate lists with detailed information, while unassociated devices receive simplified responses. This localized differentiation optimizes resource allocation efficiency without significantly increasing overall protocol complexity.
2Measurement precision
If the access point device includes device state indication in forwarding messages, then the BSS selection accuracy is improved, but the message complexity increases
Solution Approach 1:
The patent implements preliminary action by determining the wireless device's association status before composing the forwarding message to the server. This pre-determination allows the access point to selectively include device state indications and relevant device information only when necessary, improving BSS selection accuracy while minimizing unnecessary message complexity.
3Reliability
If the server provides tailored BSS candidate lists based on device authentication status, then the network performance is optimized, but the processing time increases
Solution Approach 1:
The patent applies partial action by providing different levels of BSS candidate list detail based on device authentication status. Authenticated devices receive comprehensive tailored lists with full network performance optimization, while unauthenticated devices receive simplified lists with minimal processing. This selective approach optimizes network performance for authorized devices without unnecessarily increasing processing time for all devices.

AI summary
A method to provide interoperable mechanisms for efficient use of frequency bands and channels in Wi-Fi networks, including receiving, by an access point device, a wireless request message from a wireless device, requesting information on candidate wireless networks; determining, by the access point device, whether the wireless device is associated with the access point device; and composing, by the access point device, a forwarding message to be transmitted by the access point device to a server, and including in the forwarding message an indication that the wireless device is associated with the access point device, if the wireless device is associated with the access point device.
