Method for reducing power consumption of NB-IoT module

The invention discloses a method for reducing power consumption of an NB-IoT (Narrow Band Internet of Things) module. The method comprises the following steps: S1, a terminal module generates and sends communication request data to a base station module; s2, the base station module receives the request of the terminal module for sending the communication data, and searches the starting time of the time period which can be used by the terminal module; s3, the terminal module forms the use data of the instrument equipment collected before the starting time of the time period into communication data, wherein the communication data further comprises a hash value of the use data; s4, the base station module forms forwarding data and sends the forwarding data to the communication module; s5, the communication module carries out registration verification on the ID of the terminal module and verifies the authenticity of the forwarded data; s6, the gateway module sends the forwarding data to the application module corresponding to the target network address of the gateway module; and S7, the application module extracts useful information from the forwarded data, and binds the useful information with the user ID and the positioning information. According to the invention, the power consumption of the NB-IoT module can be reduced.
