WLAN Event Reporting Frame Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing event reporting procedure in WLAN systems often transmits unnecessary event report elements, leading to increased burden and traffic in the WLAN system, resulting in inefficient utilization of wireless channels and system overload.
Innovation Solution
The proposed solution involves transmitting an event request frame with a specified event type and response limit, allowing the requested STA to send only the requested number of event report elements, thereby reducing unnecessary traffic and improving channel utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all available event report elements are included in the event report frame, then the requesting STA receives complete event information, but the WLAN system burden increases and wireless channel utilization efficiency deteriorates
Solution Approach 1:
The patent extracts only the necessary event report elements from the complete set of available events. The requesting STA specifies which event types it is interested in, and the requested STA transmits only those specific event report elements, excluding unrelated events. This extraction principle resolves the contradiction by maintaining information completeness for requested events while removing unnecessary information that causes system burden.
Solution Approach 2:
Instead of transmitting all available event report elements (excessive action), the patent implements partial action by transmitting only the subset of events that match the requesting STA's specifications. The requested STA filters the event report elements based on the requested event types, sending a partial set that is sufficient for the requesting STA's needs without the overhead of complete event transmission.
2Loss of information
If multiple event report frames are transmitted to report events for one event request, then all event information is delivered, but the system burden increases and unnecessary traffic is caused
Solution Approach 1:
The patent merges multiple event report elements into a single event report frame. Instead of transmitting separate frames for each event type or each individual event, the requested STA consolidates all requested event report elements into one comprehensive frame. This merging approach maintains complete event report delivery while reducing the number of transmissions and associated system burden.
3Quantity of substance
If all event report elements are transmitted regardless of requesting STA's intention, then complete event data is provided, but unnecessary traffic increases and channel efficiency decreases
Solution Approach 1:
The patent applies local quality by making the event report transmission tailored to each requesting STA's specific needs. The requesting STA indicates its interest in particular event types, and the requested STA adjusts the content of the event report frame accordingly. This localized approach ensures that each transmission contains the appropriate quantity and type of event data for that specific receiver, optimizing channel efficiency while maintaining data completeness for requested events.

AI summary
Provided are a WLAN management procedure, a station supporting the procedure, and a frame format for the procedure. In the management procedure, a reporting station receives a event request frame including one or more event request elements each of which comprises an event type field for specifying the event type of an event request and an event response limit field for specifying the number of requested event report elements. And, in response to the event request frame, the reporting station transmits an event response frame including event report elements for the event type specified in the event type field as many as the number specified in the event response limit field.
