In 2016, China Mobile's 4G network rapidly develops to accommodate over 1.1 million sites and serve more than 0.3 billion users. With a rapid increase in sites and users, how to ensure 4G user experience is a resounding growing high priority concern of China Mobile's mobile network construction.
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. On an ultra-dense network, Huawei's CloudRAN solution is then an optimally quintessential selection to improve network efficiency and performance whilst successfully rising to the challenge of handling issues related to depreciative user experience at the cell edge.
Huawei is committed to helping operators improve user experience and achieve business success with innovative products and solutions. The CloudRAN solution introduces cloud technology to the radio access network and adopts unified cloud architecture. Oppose to single-site control, large area management is now actualized, pertaining to the adaptive capabilities of numerous site types (macro base station, micro base station, and small cell) and differing network standards (4G, 4.5G, 5G, and Wi-Fi). Subsequent connections are established regardless of site type and network standard, allowing for the integration and optimization of resources to enhance further network efficiency and operator desired performance.
Through construction of a CloudRAN network, operators implement resources coordination and cross-site scheduling over a large area. The CloudRAN solution facilitates flexible deployment of network function units and a centralized method of control towards resource management and scheduling. The provision of a seamless user experience in ultra-dense networking scenarios is derived from reduced inter-cell interference. Users can enjoy an unsurpassed MBB networking experience anytime and anywhere.
China Mobile has deployed the CloudRAN network in locations throughout China including Nanjing, Dongguan, and Anhui. According to the KPIs shown in the deployment tests, inter-site CA helps contribute to a measured improvement of cell edge user experience by a factor of 100%. Anti-interference features such as UL CoMP and DL CoMP both significantly reduce inter-cell interference with reported user experience boasting a recent increase of over 40%. An identical CloudRAN network is scheduled for city deployment in locations such as Shanghai to meet the challenging requirements for improved user experience in ultra-dense networking scenarios.
Yang Chaobin, CMO of Huawei Wireless Network Product Line, claimed that, "Huawei prioritizes operator's interests throughout persistent innovation to aggressively respond to emerging requirements. The CloudRAN solution marks and accentuates a key direction for network evolution. 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."
