Description

Technical Field

[0002] With the development and widespread adoption of 5G wireless network technology, 5G, like 4G, will continue to utilize voice solutions based on the IMS architecture. Voice over 4G LTE networks is called VoLTE, while voice over 5G NR networks is called VoNR, commonly known as high-definition voice. Operators' ability to improve overall network voice quality directly influences user choice. Therefore, objectively analyzing the impact of mobile communication networks on voice quality is crucial.

[0003] Operators have long developed a comprehensive MOS (Metrics of Performance) voice evaluation solution for quantitative analysis and evaluation of voice quality, with acquiring the test voice as a key technology. The MOS value is a crucial metric for measuring voice quality in communication systems and ensuring user experience. It reflects end-to-end quality and is influenced by all network elements throughout the entire process. Currently, research on wireless parameters is being used to identify parameter solutions to improve MOS, such as adopting a QCI-based parameter strategy and implementing variable step-size adjustments for CQI. However, existing solutions have the following shortcomings: (1) Using a 3.5mm headphone audio interface requires separate wiring and takes up space; (2) The 3.5mm headphone jack will damage the sound quality and cannot provide a high-quality audio experience; (3) Audio acquisition and data acquisition are routed in two separate routes, which results in messy equipment routing, affects the appearance, and makes troubleshooting difficult; (4) Unable to adapt to many mobile phones with 3.5mm headphone audio interfaces on the market; (5) Voice transmission is mainly analog and is susceptible to various interferences.
