Abstract

The invention is applicable to the technical field of communication, and provides a data communication method, a relay node, a terminal node and a communication system. The method comprises: a base station distributes network addresses for the relay node and the terminal node in the communication system, and the relay node and the terminal node enter a dormant state after receiving the distributednetwork addresses; interrupting and triggering time of the relay node; the relay node is switched from a dormant state to a wake-up state; interrupting and triggering time of the terminal node; the terminal node is switched from a dormant state to a wake-up state; the terminal node sends data information to be reported to the base station through the relay node, the base station feeds back response information after receiving the data information, the relay node sends the response information to the corresponding terminal node after receiving the response information, then the terminal node enters a dormant state, and the terminal node enters the dormant state after receiving the response information. Through the application, the reliability of data transmission can be improved, the networking is simple, and the power consumption of the terminal node and the relay node can be reduced.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a data communication method, a relay node, a terminal node and a communication system. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the information age. The Internet of Things is mainly the communication between things. Unlike the communication between people, which requires high bandwidth, high speed, and frequent charging of communication equipment, the communication between things requires data transmission after a large number of devices are connected to the network. The frequency is low and the data transmission volume is small. [0003] At present, the networking methods of the Internet of Things are mainly star networking and Mesh networking. However, in the current star network, the terminal nodes often cannot comm...
