A downlink message queue processing method of lora network server

Abstract

The invention belongs to the technical field of computer and communication, and specifically relates to a method for processing a downlink message queue of a LoRa network server, comprising: designing a storage mode of a downlink message queue, and opening different downlink message processing mechanisms according to the type of uplink messages; The types include network access request message, uplink request confirmation message and uplink non-confirmation message; the network access request message makes the network server generate a network acceptance message, and the uplink request confirmation message makes the network server generate a downlink confirmation message, and different optimizations are designed according to different uplink messages The processing method will improve the transmission success rate by optimizing the processed downlink messages, integrate and send different types of messages, reduce the number of downlink message transmissions, and at the same time be able to flexibly select the sending time stamp of the downlink message, and the downlink multi-gateway Traffic is load balanced.

Description

technical field [0001] The invention belongs to the technical field of computers and communications, and in particular relates to a downlink message queue processing method of a LoRa network server. Background technique [0002] With the continuous improvement of the level of social information technology, the Internet of Things technology is also developing steadily. Faced with the rise of more and more IoT application scenarios, traditional wireless transmission technologies have been unable to meet the coverage and power consumption requirements of massive IoT devices. LoRa technology has received widespread attention due to its long-distance transmission, ultra-low device power consumption, low cost, and easy networking. The design and processing of the downlink message queue in the LoRa multi-gateway system is particularly important for improving the reception rate of downlink messages. [0003] At present, the research focus of LoRa network server based on LoRa at ho...

Problems solved by technology

At present, only the concept of downlink message queue is proposed in the LoRaWAN protocol, and no specific implementation method is provided for it. The related open source LoRa network server only simply sets the sending time stamp of downlink data, and does not combine The software and hardware status of the gateway is comprehensively analyzed, resulting in messages that may be discarded after reaching the gateway, so that the QoS of downlink messages cannot be guaranteed
