Internet of things data transmission method, device and system

An Internet of Things data transmission method, comprising:

• receiving, by a server, a first data request from a terminal device, wherein the first data request comprises a quantity N of data packets, that the terminal device is capable of continuously receiving, and a time interval for sending two consecutive data packets, where N is an integer greater than 1;
• and
• continuously sending, by the server, N data packets to the terminal device based on the first data request, wherein the N data packets comprise at least one non-confirmable Constrained Application Protocol (NON) data packet, a sending time interval between two consecutive data packets in the N data packets, and the at least one NON data packet indicates that sending a receiving response from the terminal device to the server is unnecessary.

A terminal device, comprising a memory, one or more processors, and one or more programs, wherein the one or more programs are stored in the memory, and the processor is configured to execute the one or more programs, to perform an Internet of Things data transmission, and the processor is further configured to execute a method comprising:

• sending, a first data request to a server, wherein the first data request instructs the server to continuously send a plurality of data packets, the first data request comprises a quantity N of data packets, that the terminal device is capable of continuously receiving, and a time interval for sending two consecutive data packets, where N is an integer greater than 1;
• and
• continuously receiving, N data packets from the server, wherein the N data packets comprise at least one non-confirmable Constrained Application Protocol (NON) data packet, a sending time interval between two consecutive data packets in the N data packets, and the NON data packet indicates that the terminal device sending a receiving response from the terminal device to the server is unnecessary.
