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 present invention relates to a method and system for implementing packet broadcasting based on LoRaWAN. The method includes: each LoRaWAN terminal node presets multiple identities; the multiple identities include a unicast identity, a broadcast identity and at least one reserved group broadcast identity; each LoRaWAN terminal node reports the multicast identity to the LoRaWAN server and monitors the configuration request of the LoRaWAN server; the LoRaWAN server performs multicast configuration storage and configuration distribution management; the LoRaWAN server sends a broadcast message to the LoRaWAN terminal node to Configure the multicast identity of the LoRaWAN endpoint. The invention can perform data downlink and setting synchronization for multiple terminal nodes at the same time, and realize broadcast control and multicast control.

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...
