Communication method, device, service node, communication system, and storage medium

A communication method, applied to a service node and comprising:

• sending a service node-to-device signal to a device;
• and
• receiving information transmitted by the device based on radio frequency energy;
• wherein the method further comprises:
• transmitting a security code to the device before receiving information transmitted by the device;
• wherein the service node and the device are deployed in an Internet of Things (IoT) system that harvests energy from environmental signals;
• and
• wherein the information is transmitted by the device in a manner adapted to a simplified two-layer protocol stack of the device, the simplified two-layer protocol stack consisting of a physical layer protocol stack and a high-layer protocol stack configured to perform a function of segmenting communication data.

A device, comprising a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein when executing the program, the processor performs a communication method, wherein the communication method comprises:

• harvesting radio frequency energy by receiving a radio frequency signal of a radio frequency energy source node;
• and
• transmitting information to a service node based on the radio frequency energy;
• wherein the method further comprises:
• receiving a security code sent by the service node before transmitting the information to the service node;
• wherein the service node and the device are deployed in an Internet of Things (IoT) system that harvests energy from environmental signals;
• and
• wherein an air interface protocol stack supported by the device is simplified into a two-layer protocol stack, and the two-layer protocol stack consists of a physical layer protocol stack and a high-layer protocol stack, and wherein a function performed by the high-layer protocol stack comprises segmenting communication data.
