Wireless Terminal QoE Reporting With Device Identifier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reporting quality of experience (QoE) in digital content reception over cellular networks primarily rely on subscriber information, limiting the depth of analysis and failing to account for device-specific factors that could impact user experience.
Innovation Solution
A method and system for wireless terminals and network nodes to detect the end of digital content reception, obtain a device identifier, generate a reception reporting message including quality of experience metrics, and transmit it to a network node, allowing for analysis based on both subscriber and device information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only subscriber information (MSISDN) is included in reception reports, then the reporting system remains simple and easy to implement, but the depth of quality of experience analysis is limited
Solution Approach 1:
The patent segments the identification information into two parts: subscriber information (MSISDN) and device information (device identifier). This segmentation allows the system to maintain simplicity in subscriber identification while adding device-specific dimensions for deeper QoE analysis without overwhelming complexity
Solution Approach 2:
The patent adds a new dimension to the analysis by incorporating device identifier alongside the traditional subscriber identifier. This dimensional expansion enables multi-dimensional QoE analysis (both subscriber-level and device-level) without completely redesigning the existing reporting framework
2Adaptability or versatility
If device identifier is added to reception reports, then terminal type analysis becomes possible, but the reporting message size and processing complexity increase
Solution Approach 1:
The device identifier field in the reception report serves multiple functions: it enables terminal type identification, supports device-specific QoE analysis, and allows correlation of performance data across different devices. This multi-functionality justifies the added complexity by providing versatile analytical capabilities
3Measurement precision
If comprehensive quality of experience metrics are collected for all devices, then service issues can be precisely identified, but the amount of data to be processed and analyzed increases significantly
Solution Approach 1:
The patent enables localized analysis by device type rather than requiring uniform analysis of all data. By tagging reports with device identifiers, the system can apply device-specific analysis methods and thresholds, processing data more efficiently while maintaining high precision in identifying service issues for each terminal type
Data Source
AI summary
It is provided a method for reporting quality of experience of receiving digital content over a cellular network. The method is performed in a wireless terminal and comprises the steps of: detecting an end of the reception of the digital content; obtaining a device identifier of the wireless terminal; generating a reception reporting message comprising the device identifier and quality of experience metrics related to the reception of the digital content; and transmitting the reception reporting message to a network node. Corresponding, wireless terminal, network node, computer programs and computer program products are also provided.
