In internet of things network

it is difficult to manage the existing IoT card and identify the IoT customer service

based on network big data

research on the end-to-end support ability of the internet of things industry customers

based on the theory of "four layers and three dimensions" perception evaluation model and "qualitative classification" method

fully mining and analyzing network data of IoT card

find out the service characteristics of different systems and industries and customers

and then through the integration of artificial intelligence technology and big data capability

the operation and maintenance capability can be more intelligent and automation

f inally realize the active operation and maintenance ability on internet of things industry customer perception. This achievement fills in the gap of the endto-end support ability on internet of things service in the industry

plays an important role in shortening the time of fault handling

improving the network quality

reducing the labor operation and maintenance cost.
