Abstract

The embodiment of the invention provides a LoRa network channel access method and system, a terminal, a gateway and a server. The method comprises the steps of: prior to message sending to a LoRa gateway, monitoring whether a channel to be selected in a channel list to be selected is idle or not; if a first channel to be selected is idle, monitoring whether the first channel to be selected is occupied by LoRa leading signals after the first duration is delay at will; if the first channel to be selected is not occupied, sending an LoRa message to the LoRa gateway through the first channel to beselected. The LoRa network channel access method and system, the terminal, the gateway and the server solve the problems that the LoRa channel is high in collision, the utilization is low, the LoRa terminal is multiple in retransmission and the power consumption is high, and the air interface utilization is improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a LoRa network channel access method, terminal, gateway, server and system. Background technique [0002] Channel access is the core function of the Media Access Control (Mac) layer, and its purpose is mainly to arrange and design reasonable use of channel resources for communication. If only one device sends data to another device, there is no need to consider too many channel access issues. The device can monopolize all channel resources, which include frequency, time, space, power, etc.; but when multiple devices communicate For example, when two terminal devices communicate with the host at the same time, a collision will occur. At this time, channel access technology is required to reasonably arrange the channel resources occupied by each device to avoid communication conflicts between different devices. [0003] The currently commonly u...
