According to the NB-IOT equipment identity activation method, information verification is carried out on the NB-IOT equipment, a verification result is returned to the NB-IOT equipment, only the NB-IOT equipment passing the verification can access the cellular network, corresponding specific functions are realized, and cellular network congestion caused by frequent sending of invalid network requests by the NB-IOT equipment is avoided. Meanwhile, by setting the reconnection times and the sleep time of the NB-IOT equipment, the reconnection times and the sleep time of the NB-IOT equipment for establishing the network connection are limited, so that the congestion of the cellular network is reduced, the cellular network resources are saved, and the connection speed of the cellular network is effectively improved.
