China Unicom Supports Production Resumption in Shanghai Amid Pandemic

China United Network Communications Group Co., Ltd. (China Unicom) has made plans to support resumption of production in Shanghai based on several components of its network guaranteeing technologies since April 22 while ensuring pandemic prevention and control and boosting economic and social development.

Focusing on network demand

According to a list of key enterprises to resume production, China Unicom's branch in Shanghai used artificial intelligence-based automatic identification technology to screen areas covered by more than 18,000 3G, 4G and 5G base stations.

Based on experience of the network-supported telephone traffic model, China Unicom adopted other digital methods to give an accurate assessment of the production resumption area, thus enabling quick error targeting to protect users' network experience.

In addition, the digital process helps highly-efficient problem-solving and visible and controllable operation during the entire process.

At present, 75 high-load base stations are under control and further optimization will continue. 

Targeting user experience

China Unicom in Shanghai adopted technological methods to survey areas where workers have returned to their positions and used big data and accurate scenario matching technologies to identify targets and track their movements.

The company also launched a system that can automatically identify hotspots in areas where production has been resumed based on 5G automatic optimizing technology and the flexibility and diversification of 5G signals.

Thanks to the system, the company is able to realize fast deployment in typical scenarios and accurately match special scenes; it can also respond effectively to complex wireless environments and improve 5G users' perceptions within them.

With the automatic parameter adjustment function, the system can in addition dispatch power according to the telephone traffic conditions to solve load and coverage problems.

Supporting key enterprises to resume production

In respond to production resumption amid the pandemic, China Unicom in Shanghai allocated machines to support workers returning to their positions.

At the entrance of a power generation company in Shanghai, workers can complete identification and health checks by looking at the camera and scanning their identification card on the machine, which is safe and efficient.

China Unicom also played a key role in guaranteeing a smooth communication network for the intensified and continuous nucleic acid tests.
