Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to perform targeted network optimization based on quality of experience (QoE) measurement results from terminal devices, leading to suboptimal user experience in services like streaming and multimedia broadcast.
Innovation Solution
Terminal devices report application layer measurement results with indication information specifying the cell where the service is received, enabling network devices to optimize broadcast service configurations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network side performs QoE measurement collection configuration on the terminal device, then the terminal device can obtain user experience data, but the network side cannot perform targeted network optimization based on the measurement results
Solution Approach 1:
The patent introduces indication information as an intermediary element that connects the measurement result to the specific cell. The terminal device includes this indication information in the measurement report, which then serves as the mediator enabling the network side to identify the specific cell and perform targeted optimization. Without this intermediary, the measurement result remains disconnected from the network optimization process.
Solution Approach 2:
The patent establishes a feedback loop where the terminal device reports measurement results back to the network side with included indication information about the serving cell. This feedback mechanism enables the network side to receive quantitative user experience data and use it to optimize the specific cell's broadcast service configuration, closing the loop between measurement and optimization.
2Device complexity
If the terminal device reports measurement results without cell identification information, then the reporting process is simpler, but the network side cannot identify which cell needs optimization
Solution Approach 1:
The patent merges the cell identification information with the measurement result reporting mechanism. The indication information is integrated into the measurement report that the terminal device sends to the network side, combining what would otherwise be separate elements (cell identity and measurement data) into a unified report structure. This merging enables the network side to receive both the measurement results and the associated cell identification in a single message.
3Measurement precision
If the network side collects detailed measurement results from multiple cells, then the optimization accuracy improves, but the signaling overhead increases
Solution Approach 1:
The patent applies local quality by focusing the measurement and reporting mechanism on the specific serving cell where the terminal device is currently located and receiving broadcast services. Rather than requiring detailed measurements from multiple cells, the system optimizes for the local serving cell context, which reduces the scope of measurement reporting and consequently reduces signaling overhead while maintaining sufficient optimization accuracy for the active service area.
