en.Wedoany.com Reported - Under the guidance of China Mobile Group's Planning and Construction Department, Guangdong Mobile, in collaboration with Huawei, has completed the nation's first end-to-end verification of user-level dynamic slicing technology in Shenzhen, marking a shift for 5G-A networks from a "best-effort" general service to a new experience era of "on-demand target rate assurance." The verification was conducted in three heavy-load scenarios: universities, subways, and high-speed railways. Field tests show that dynamic slicing significantly reduces experience fluctuations in mobile heavy-load scenarios.
For a long time, industry network assurance solutions have primarily adopted a "priority occupation" slicing model, ensuring services through scheduling priority. However, fixed RB quotas struggle to adapt to dynamically changing wireless environments, leading to resource redundancy or insufficient assurance when channel conditions fluctuate. The dynamic slicing solution verified this time breaks away from the "fixed resource priority occupation" approach, with its core being two underlying capabilities: intelligent spectral efficiency estimation and dynamic resource reservation. Instead of reserving resources fixedly, the system senses network load and user location in real time, dynamically calculates spectrum utilization efficiency, and flexibly allocates assurance resources: resources are precisely allocated when VIP users have demands, and automatically released for shared use by all users during idle periods.
During tests at Shenzhen University's Yuehai Campus, even with background traffic at full capacity, users at both mid-near points with good signals (RSRP -81dBm) and far points at coverage edges (RSRP -102dBm) were able to stably achieve the target assured rate, with no significant experience fluctuations due to location changes. On Shenzhen Metro Line 4 and the Xiamen-Shenzhen High-Speed Railway, dynamic slicing, through real-time channel estimation and dynamic resource scheduling, significantly reduced the proportion of low-rate occurrences in heavy-load mobile scenarios, with measured short video stalling rates dropping by 60%.
The implementation of dynamic slicing achieves a triple value upgrade in experience, service, and efficiency. In terms of experience, assurance scope is expanded from fixed scenarios to all scenarios; in service, users do not need to change terminals or manually toggle settings—they automatically enjoy exclusive assurance upon entering coverage areas; in efficiency, the flexible scheduling mechanism balances differentiated assurance with basic assurance, maximizing network efficiency.
Currently, Guangdong Mobile has completed the end-to-end full process for dynamic slicing, and the accompanying SVIP product benefits will undergo friendly user trials on a large scale in Shenzhen's Bantian area. For individual users, this product will provide VIP users with target rate assurance in high-load scenarios; for industry customers, dynamic slicing capabilities will be opened as atomic capabilities, empowering vertical industries such as government and military, industrial, and cultural tourism sectors.
