Huawei recently announced its use of the CloudRAN architecture to help China Mobile improve network performance, handle issues related to the interference at the cell edge on an ultra-dense network, and provide better user experience.
The CloudRAN solution which introduces cloud technology to the radio access network and adopts unified cloud architecture has been deployed in locations throughout China including Nanjing, Dongguan, and Anhui. The solution is also scheduled for city deployment in locations such as Shanghai to improve user experience in ultra-dense networking scenarios.
In 2016, China Mobile's 4G network rapidly developed to accommodate over 1.1 million sites and serve more than 0.3 billion users. The 4G network, as is known to all, uses single-frequency networking. LTE cell edge users receive poorer service experience in comparison to users located in other areas due to co-channel interference. As site density increases, a bottleneck of diminished user experience at the cell edge is increasingly apparent.
According to Huawei, as opposed to single-site control, large area management is now critical in heterogeneous networks especially with numerous site types (macro base station, micro base station, and small cell) and with different network types such as 4G, 4.5G, and Wi-Fi. CloudRAN helps operators to implement resources coordination and cross-site scheduling over a large area. It facilitates flexible deployment of network function units and a centralized method of control towards resource management and scheduling, said Huawei.

Huawei CloudRAN network provides an abundance of diverse multi-technology integrated options coupled with resource coordination and scheduling. These high aspirations and commendable endeavors support China Mobile's improvement of user experience and mission to embark on a new chapter of network evolution.
