ZTE Corporation has published a white paper on 5G SA commercial deployment, published by Mobile World Live. The white paper demonstrates that SA is the target architecture of 5G and lays solid foundation for fully realizing 5G application value.

The white paper elaborates on 5G SA challenges and solutions, covering seamless coverage, multi-RAT co-existence, end-to-end network slicing, and 5G business-oriented network and service applications.

In terms of seamless coverage, three factors like the serialized 5G NR products for the flexible full-scenario coverage, uplink enhancement technology, high-frequency and low-frequency coordinate networking are the key to the cost-effective seamless coverage. 

Meanwhile, convergent architecture core network, NSA/SA dual-mode BTS and SuperDSS can achieve the co-existence and smooth evolution of multi-RAT networks.

As the critical function of 5G, network slicing has been realized in end-to-end network and management system. Some cutting-edge technologies and products, such as end-to-end slicing, lite 5GC, integrated UPF and MEC have been introduced to industry private network deployments and service applications.

Moreover, the white paper has also introduced some successful business-oriented 5G application cases, for example, Tianjin smart port's 5G remote control of quay cranes, and ZTE Nanjing smart factory, in which ZTE's 5G equipment is produced efficiently with the 5G network. 

In addition, the white paper expects that the 3GPP R16-based 5G network will be put into commercial use in 2022 to further explore the values of 5G applications.
