Network automation refers to adopting automatic operation flows, a series of automatic tools, big data and AI to implement end-to-end automation of network services and management, including network planning, construction, maintenance, optimization, and operation.
With the deployment of 5G networks, network O&M faces huge challenges, so it is a must to achieve automatic and intelligent transformation of O&M. However, such transformation is a process of long-term evolution. It needs to be promoted step by step according to the legacy network situation, cloud transformation progress, maturity of 5G and IoT technologies and operators’ network evolution strategy. The industry usually divides the network intelligence process into five stages: L1 computer-assisted operation, L2 preliminary intelligent, L3 intermediate intelligent, L4 advanced intelligent and L5 fully intelligent.
