ZTE, China Mobile verify HSR 4G optimizing solution

NEW DELHI: ZTE Corporation has announced that, with China Mobile Research Institute and China Mobile Group Zhejiang Company Limited, it has completed the performance verification and deployment of a solution to optimize the high-speed rail (HSR) 4G user experience in the Shanghai-Hangzhou HSR (Jiaxing section) providing excellent network services for 4G users.

ZTE assists China Mobile in planning and construction to ensure the dominance of private network signals in HSR lines. The verified solution for optimizing the HSR 4G experience features unique priority scheduling for HSR users. It also identifies HSR and non-HSR users by using a precise scheduling algorithm that guarantees priority services for fast-moving 4G users on the HSR, thereby significantly improving the user experience in HSR stations and in the densely-populated areas that the trains travel through.

The test result shows that, after the function of priority scheduling for HSR users is enabled, the uplink and downlink resources allocated to fast-moving 4G users on the HSR increase sharply when the trains go through platforms, significantly enhancing the service rate while ensuring high quality of service (QoS) of voice over long-term evolution (VoLTE) services for both HSR and non-HSR users. This optimization solution will help China Mobile provide users with high-quality VoLTE service and excellent data service for 4G HSR users.

As of now, ZTE has been involved in the network construction of 27 HSR lines in 14 provinces in China, helping operators bring better 4G data services and VoLTE service experience to HSR users.
