As an optional implementation manner, after the forwarding node determines that the total number of terminal devices that initiate the Internet of Things data in the wireless coverage of the forwarding node exceeds the preset number specified by the forwarding node, and the forwarding node queries the port through the weather information. Before the cloud service platform corresponding to the weather information query port initiates an instant weather type query request including the terminal device address included in the Internet of Things data initiated by the terminal device, the forwarding node may perform the following steps:

The forwarding node identifies whether the forwarding node is configured to allow access to the cloud service platform, and if the forwarding node is configured to allow access to the cloud service platform, determining whether the current system time of the forwarding node is within the time period;
