Beacon Frame Storage Capability Advertising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users connecting to WiFi networks cannot a priori know the storage capabilities of available networks, requiring them to disconnect and reconnect to discover storage resources, which is cumbersome, especially in areas with multiple networks.
Innovation Solution
Incorporating data about storage capabilities into beacon frames transmitted by WiFi access points, allowing terminals to identify and select networks with matching storage resources without prior connection, by including a wireless local area network identifier and storage capability data within the beacon frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users connect to WiFi networks to discover storage capabilities, then storage information can be obtained, but the process requires disconnecting and reconnecting to multiple networks which is time-consuming and cumbersome
Solution Approach 1:
The patent applies preliminary action by including storage capability information in beacon frames that are transmitted periodically by access points before any connection is established. This allows terminals to discover storage resources in advance by simply scanning for beacon frames, eliminating the need to connect and disconnect from multiple networks to gather storage information.
2Ease of operation
If storage capability data is included in beacon frames, then terminals can identify storage resources without prior connection, but the beacon frame structure becomes more complex
Solution Approach 1:
The patent applies the nested doll principle by embedding storage capability information elements within the existing beacon frame structure. The storage information is nested as information elements inside the beacon frame, which itself is part of the WiFi protocol structure. This allows additional functionality to be added without fundamentally changing the beacon frame architecture.
3Adaptability or versatility
If multiple WiFi networks are available at a given place, then users have more network choices, but it becomes more difficult to identify which network has the desired storage capabilities
Solution Approach 1:
The patent applies the color changes principle by using information elements with specific identifiers and structures within beacon frames to clearly mark and differentiate storage capability information. This structured approach with identifiable markers makes it easy for terminals to quickly scan and compare storage capabilities across multiple networks without confusion.

AI summary
A method for advertising capabilities of at least one storage (ST1) accessible via a wireless local area network (WLAM1) comprising at least one wireless access point (AP1), this wireless access point periodically transmitting beacon frames containing a wireless local area network identifier designating this network, comprises the step of inserting, in each beacon frame transmitted by a wireless access point (AP1), data describing the capabilities of at least one storage (ST1) accessible via the wireless local area network (WLAN1) designated by this wireless local area network identifier.
