QoE Indicator Segmentation for AP Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clients lack sufficient information to select an Access Point (AP) that provides the best Quality-of-Experience (QoE), as existing QoE attributes are limited and transmissions for sending these attributes contribute to network congestion.
Innovation Solution
The solution involves determining values for multiple Quality-of-Experience (QoE) attributes, calculating a QoE indicator based on these values, and sending this indicator to clients. Additionally, clients can request and receive QoE reports, which include detailed QoE attributes, to aid in selecting the optimal AP.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple QoE attributes are determined and transmitted to clients, then clients can make informed decisions about AP selection, but network congestion increases due to additional transmissions
Solution Approach 1:
The patent segments QoE information into two distinct formats: QoE indicators (concise summaries) and QoE reports (detailed attribute sets). Clients can receive indicators for all visible APs and optionally request detailed reports only for APs of interest, reducing unnecessary data transmission while maintaining information completeness.
Solution Approach 2:
The patent extracts essential QoE characteristics into compact indicators that can be transmitted efficiently to all clients. These indicators contain the most critical QoE information in a condensed format, allowing clients to make preliminary assessments without receiving complete detailed reports for all APs.
2Productivity
If QoE indicators are sent to all clients for all visible APs, then clients can efficiently compare AP options, but transmission overhead and network congestion increase
Solution Approach 1:
The patent divides QoE information delivery into two segments: universal indicators sent to all clients for all visible APs, and detailed reports sent only upon client request for specific APs. This segmentation allows efficient comparison based on indicators while reducing overall data transmission volume.
Solution Approach 2:
The patent implements partial action by sending complete QoE indicators for all APs to enable comprehensive comparison, while providing detailed reports only for APs that clients selectively request. This avoids the excessive transmission of complete reports for all APs to all clients.
3Loss of information
If detailed QoE reports are provided for all APs, then clients have comprehensive information for selection, but the complexity of information processing increases
Solution Approach 1:
The patent segments information complexity by providing concise QoE indicators as the primary comparison tool and detailed reports as supplementary information. Clients process simple indicators for all APs and only request detailed reports for APs they are seriously considering, reducing overall processing complexity.
Solution Approach 2:
The patent performs preliminary filtering by having clients compare QoE indicators first to identify promising APs. Only after this preliminary assessment do clients request detailed reports for specific APs, reducing the amount of complex information that needs to be processed at any one time.
Data Source
AI summary
Sending Quality-of-Experience (QoE) information to clients for selecting an Access Point (AP) may be provided. Sending QoE information can include determining values for a plurality of QoE attributes. Based on the values for the plurality of QoE attributes, a QoE indicator is determined. The QoE indicator is sent to a client, wherein the client is operable to use the QoE indicator to select an Access Point (AP) to connect to.
