Abstract

The invention relates to the technical field of Internet of Things, and provides an Internet-of-Things system dormancy control method based on an NB-IoT communication protocol stack, and the method comprises the steps: step 100, obtaining a dormancy trigger event; step 200, reporting the dormancy trigger event to a power management module, and judging whether the NB-IoT communication protocol stack allows dormancy or not by the power management module; step 300, enabling the NB-IoT communication protocol stack to update the general user identification module file; step 400, enabling the NB-IoT communication protocol stack to inform a physical layer that the power is about to be cut off; step 500, enabling the NB-IoT communication protocol stack to sleep the information to be stored; step 600, enabling the NB-IoT communication protocol stack to register a dormancy timer in the power management module, and determine the dormancy state of the universal user identification module at the same time; and step 700, enabling the power management module to control the real-time clock to operate the sleep timer. Electric energy consumption of equipment can be reduced, and the service life of the battery is prolonged.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to an Internet of Things system dormancy control method based on the NB-IoT communication protocol stack. Background technique [0002] With the development of NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) technology, the base station construction of operators is becoming more and more perfect. The NB-IoT technology on the market has been applied to many industries, such as smart door locks and shared bicycles. , smoke alarm, smart water meter and so on. [0003] Before the emergence of NB-IoT technology, IoT devices were usually realized by the cooperation of external control MCU and communication modules. In order to control power consumption, the communication module is usually powered off when the device is sleeping, and the MCU registers the sleep duration to the real-time clock. The disadvantage of this sleep mode is that when ...
