Innovation Solution
A method and device for broadcasting QoE configuration in wireless communication systems, involving terminals and base stations, where terminals receive QoE configuration information, perform measurements, and transmit results, while base stations transmit configuration information and receive measurement results, utilizing transceivers and processors to facilitate this process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoE configuration information is transmitted individually to each terminal, then measurement accuracy and service customization are improved, but signaling overhead and network resource consumption increase
Solution Approach 1:
The patent merges QoE configuration information into broadcast system information (SIB) that is transmitted once to all terminals simultaneously. This combines what would otherwise be multiple individual unicast transmissions into a single efficient broadcast, reducing signaling overhead while ensuring all terminals receive the necessary QoE measurement configuration.
Solution Approach 2:
The broadcast QoE configuration serves multiple terminals simultaneously with a single transmission. The configuration information is designed to be universally applicable across multiple terminals, allowing one message to fulfill the configuration need for many devices rather than requiring individual customized transmissions.
2Loss of information
If QoE configuration is broadcast to all terminals, then signaling overhead is reduced, but irrelevant terminals receive unnecessary information increasing processing load
Solution Approach 1:
The patent segments QoE configuration information by organizing it into distinct information elements with specific identifiers. Each terminal can identify and process only the configuration segments relevant to its subscribed services, filtering out irrelevant portions efficiently. This segmentation allows broad broadcast distribution while maintaining selective processing at the terminal level.
3Measurement precision
If individual QoE measurement reporting is required from each terminal, then network optimization precision is improved, but uplink signaling overhead and network processing complexity increase
Solution Approach 1:
The patent enables terminals to share QoE measurement results with each other through a copying mechanism where one terminal's measurement data can be reused by other terminals with similar service profiles. This reduces the need for every terminal to independently report measurements, lowering uplink signaling overhead while maintaining network optimization precision through shared measurement intelligence.
