Before the data element is encapsulated, the number of the target terminal devices whose device type is the target device type and the reported frequency is lower than the preset reporting frequency, and the number of the target terminal devices is determined to be a preset number. Threshold, when the number of the target terminal devices reaches a preset number threshold, triggering the above operation of encapsulating all the Internet of Things data into data elements.

It can be seen that the system for selecting the forwarding path for data reporting in the Internet of Things described in FIG. 6 can select two forwarding paths for the IoT data that are of interest to the aggregation unit and report the lower frequency, wherein one forwarding path is used as the primary forwarding path, and A forwarding path is used as the secondary forwarding path. When the primary forwarding path fails to be reported, the secondary forwarding path is reported. This improves the reliability of the aggregation unit receiving the IoT data that is of interest and has a lower reporting frequency, thus ensuring that the aggregation unit can Quickly process IoT data of interest to it.
