Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice quality assessment methods in wireless communications systems can only calculate voice quality between user equipment and an access node, failing to provide end-to-end voice quality assessment between different user equipment.
Innovation Solution
A method and apparatus that obtain transmission error code parameters from uplink and downlink channels of different user equipment to generate an end-to-end voice quality index using pre-established or selected voice quality index calculation models.

Engineering Contradiction Analysis
1Measurement precision
If existing voice quality assessment methods are used, then voice quality between user equipment and access node can be calculated, but end-to-end voice quality assessment between different user equipments cannot be satisfied
Solution Approach 1:
The assessment apparatus is designed to perform multiple functions: it can assess voice quality between user equipment and access nodes (original function) and also between different user equipments (new function). The system achieves this by obtaining transmission error code parameters from multiple sources (uplink of first UE, downlink of second UE) and generating end-to-end VQI that covers the complete communication path between UEs.
2Measurement precision
If transmission error code parameters from multiple channels are obtained, then end-to-end voice quality index can be generated, but system complexity increases
Solution Approach 1:
The end-to-end voice quality assessment is segmented into distinct components: obtaining uplink transmission error code parameter from first access node, obtaining downlink transmission error code parameter from second access node, and generating the end-to-end VQI by combining these parameters. This segmentation allows the system to manage complexity by handling each channel's parameters separately and then integrating them through standardized processing steps.
