Abstract

The invention provides an Internet of Things control method, system and device and a storage medium, and the method comprises the steps: presetting a data length threshold value, and starting flow control when the total length of service data is judged to be greater than or equal to the data length threshold value, so as to enable a data link layer to stop receiving new service data; the base station sending a receiving state report to the terminal so as to empty the sending window; after the sending window is emptied, updating the total length of the service data, and when it is judged that the updated total length of the service data is smaller than the data length threshold value, relieving the flow control. According to the Internet of Things control method, the total length of the service data received by the data link layer in the uplink service is controlled by starting flow control, extrusion of a sending window is avoided, uplink service time delay is reduced, and power consumption is reduced. The invention further provides a system, equipment and a storage medium for implementing the Internet of Things control method.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things communication, in particular to an Internet of Things control method, system, device and storage medium. Background technique [0002] Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth to reduce deployment costs and achieve smooth upgrades. [0003] Cost and power consumption are important indicators of NB-IoT IoT chips. Among them, the corresponding buffer size of the sending window and receiving window in the lower layer occupies random access memory space. The consumption of random access memory is mainly reflected in global variables and stacks. Global variables and stacks occupy a large amount of random access memory space. , the cost is higher; the power consumption is reflected in the business working hours, the longer the working hours, ...
