Following China Mobile's global launch of the industry's first "native AI-powered noise reduction" in December 2025, China Mobile Henan has completed beta user recruitment for Pure Voice Calling. This innovative technology has been thoroughly refined and optimized on the live network in Henan province for three months, and has officially entered commercial trials. The first group of users in Zhengzhou, the capital of Henan, have already enjoyed crystal-clear call quality, even in noisy environments.
Three Months of Efforts: From Launch to Fine-Tuning
Over the past three months, the technical team of China Mobile Henan has not only rolled out the noise reduction function, but also enhanced network performance and fine-tuned usage scenarios. The technical team collected a broad set of local noise samples from typical environments. They focused on high-interference calling scenarios that users in Henan frequently encounter, such as shopping malls, transit hubs, street-side shops, and windy conditions. Using tens of thousands of live-network voice data samples with different signal-to-noise ratios and noise durations, the team conducted iterative model training. In addition, they developed a closed-loop fine-tuning system anchored in a professional acoustic laboratory. The system integrates objective indicator testing and subjective user experience evaluation. This ensures that the noise reduction consistently achieves superior results across complex real-world environments.
Beta User Experiences: From "Usable" to "Can't Live Without"
Beta recruitment is centered on Zhengzhou, targeting China Mobile user groups with high requirements on call quality, such as business professionals, frequent field workers, and commuters using various means of transportation. Beta users have already experienced the noise reduction service, which operates seamlessly on both the uplink and downlink voice channels—without requiring any terminal change or additional app installation.
An official from China Mobile Henan noted that this initial launch is only the beginning. The key to optimizing the service, they emphasized, lies in gathering user experiences and feedback from real-world application scenarios. The official added that they aim to further test the technology's stability and user experiences in live network conditions, and collect feedback from users to gain valuable insights essential for large-scale commercial use and differentiated service delivery.
From High-End Users to Differentiated Service Experiences
By capitalizing on its pioneering role in merging 5G-A and AI technologies, China Mobile Henan has enhanced its voice network capabilities with Pure Voice Calling, laying a solid foundation for delivering tailored benefits to different user groups. Moreover, Pure Voice Calling will be integrated into differentiated service assurance as a core application scenario.
China Mobile Henan remains committed to addressing the evolving needs of high-value customers. The company will provide perceivable and personalized communication in emerging scenarios, such as family calling, smart healthcare consultations, and outdoor live streaming. This will elevate their offerings from simply reliable connections to exceptional experiences.
Moving forward, China Mobile Henan will continue to collaborate with industry partners to drive innovation and deliver more optimal and tailored calling experiences for users. At the same time, the company is exploring a sustainable path to revitalize traditional services, redefining their relevance within the sector.
