Fuente: Wipo "IOT" The invention provides an industrial Internet of Things equipment control method and system based on 5g, belongs to the technical field of Internet of Things, and is used for reducing the time delay of inventory by taking a group as granularity. The method is applied to an access network device, and the method comprises the steps that the access network device determines to execute an inventory task of a group, the group comprises M environmental Internet of Things (A-IoT) terminals, and M is an integer greater than 1; in response to an inventory task of a group, an access network device obtains respective device identifiers of M A-IoT terminals from the M A-IoT terminals, inventory opportunities of the M A-IoT terminals are concentrated, inventory opportunities of M-1 A-IoT terminals in the M A-IoT terminals are determined at least based on an inventory opportunity of a target A-IoT terminal, the target A-IoT terminal is the first inventory terminal in the M A-IoT terminals, and the inventory opportunities of the M-1 A-IoT terminals in the M A-IoT terminals are determined at least based on the inventory opportunities of the M-1 A-IoT terminals in the M A-IoT terminals. The M-1 A-IoT terminals are other terminals in the M A-IoT terminals except the target A-IoT terminal.
