The world is undergoing the greatest changes in a century. Under such backgrounds that COVID-19 sweeps the globe, the uncertainty of international situation is intensifying, a new round of scientific & technological revolution and industrial transformation are rising up luxuriantly, all walks of life are thinking about and exploring the future direction of their development. As the leading force of a new round of scientific & technological revolution and industrial change, the ICT (information and communication technology) industry has profoundly influenced and changed the model of economic and social development, people’s production and life style. It has become an important engine of scientific & technical innovation and economic growth. Especially in recent years, with the continuous innovation and wide applications of emerging ICT technologies represented by 5G, AI, Cloud Native, blockchain and MEC, the digital transformation of the whole society has been further accelerated. As the backbone of cyberpower, digital China and smart society, telecom operators shoulder the historical responsibility of better meeting people’s yearning for a better life, helping to realize China’s industrial transformation, upgrading and high-quality development, through technical & application innovation and integrated innovation.

China Unicom has long adhered to the innovation-driven development strategy, closely focused on the development trend of industrial technology and changes in customer demands, continued to promote network innovation and transformation and actively built a leading new-generation information and communication infrastructure. China Unicom released the new generation network architecture CUBE-Net 2.0 in 2015, proposed the network development vision of “New Network, New Services and New Ecology” and “decoupled and intensive network architecture for dual centers of terminal and cloud”. CUBE-Net 2.0 is based on the networking principle of leading network service capability and optimal overall efficiency under multi-resource collaboration, serving the two centers of “subscribers” and “data”. It realizes network gene reconstruction by multidimensional decoupling in deployment, service and function. Base on the core technologies as SDN, NFV and Cloud and ultra-wide network and data center, it guides to construct a cube network which features cloud network collaboration, changes as per demands and flexibility, to realize “Network as a Service (NaaS)” through the cloud service plane and intensification network operating.
