Hello, there are 16 pilot cities in China Unicom, and each pilot city has different tasks: Shenyang (industrial control), Tianjin (smart transportation), Qingdao (smart port), Nanjing (smart education), Shanghai (marginal computing), Hangzhou (e-commerce), Fuzhou (smart placement) and Shenzhen (smart finance). In addition, China Unicom also launched MEC edge cloud projects in Beijing, Hebei, Guangdong and Fujian provinces 15. China Unicom should take MEC as an opportunity to build the edge cloud industry ecology in an all-round way, and gradually realize the smooth evolution to 5G, and plan to realize the sharing platform of multiple network elements in 2020. Thank you.
