Problems solved by technology

[0002] In the standard of CLASS C / CLASS B mode based on LoRaWAN, the data downlink of the server can only be downlinked to a single terminal node, and cannot be downlinked to multiple terminal nodes at the same time
Since multiple terminal nodes cannot achieve synchronous reception when they are downlinking, the existing methods usually send data to different terminal nodes in turn or provide a delay mechanism for the downlinking of each terminal node, but this is inefficient and real-time The performance is also poor, and data synchronization cannot be achieved

Abstract

The invention relates to a method and a system for realizing packet broadcast based on LoRaWAN. The method comprises the following steps: presetting a plurality of identities for each LoRaWAN terminalnode, wherein the plurality of identities comprise a unicast identity, a broadcast identity and at least one reserved multicast identity; enabling each LoRaWAN terminal node to report a multicast identity to the LoRaWAN server and monitor a configuration request of the LoRaWAN server; enabling the LoRaWAN server to carry out multicast configuration storage and configuration issuing management; and enabling the LoRaWAN server to send a broadcast message to the LoRaWAN terminal node so as to configure the multicast identity of the LoRaWAN terminal node. According to the invention, data downlinkand setting synchronization can be carried out on a plurality of terminal nodes at the same time, and broadcast control and multicast control are realized.

Description

technical field [0001] The present invention relates to the technical field of LoRaWAN, in particular to a method and system for implementing packet broadcasting based on LoRaWAN. Background technique [0002] In the standard of CLASS C / CLASS B mode based on LoRaWAN, the data downlink of the server can only be downlinked to a single terminal node, and cannot be downlinked to multiple terminal nodes at the same time. Since multiple terminal nodes cannot achieve synchronous reception when they are downlinking, the existing methods usually send data to different terminal nodes in turn or provide a delay mechanism for the downlinking of each terminal node, but this is inefficient and real-time The performance is also poor, and data synchronization cannot be achieved. [0003] In order to solve the current shortcomings of LoRaWAN, and realize the ability to perform multi-point and simultaneously control the downlink of terminal node data in the mode of CLASS C / CLASS B, a mechani...
