The NB-IoT supports cellular data connectivity for low power devices over a wide area network. NB-IoT supports efficient connectivity for devices with long standby time and high requirements for network connectivity. The NB-IOT data packet has the characteristics that: small data, low frequency. Although the NB-IOT terminal sends small packets, due to the massive deployment of the NB-IOT terminal and the characteristics of the small packets, the packet sending needs to be controlled. The existing standard introduces an access point name Rate Control APN Rate Control parameter for transmission Rate Control, for example, based on the APN Rate Control parameter, it can limit sending at most n messages per user per day/week/month.
