Background
In the era of Internet of Things, carriers own IoT special communication network (such as NB-IoT, 5G), and cloud network is highly integrated. At the same time, there is a mature system of government-enterprise sales and service. It has become the consensus of major carriers around the world to build general or industry-specific IoT platforms (including AEP and DMP) to provide value-added services of the IoT and build an ecosystem through the platforms, acquire and accumulate a large amount of industry data.
