Problems solved by technology

[0003] It can be seen that the downlink methods of class A and class B are completely different. The existing solution needs to judge whether the terminal is in class A or class B working mode before calling the interface, and then use different downlink interfaces according to different working modes.

Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples.

[0014] A data downlink method compatible with CLASS A and CLASS B. When the LoRaWAN server receives downlink data to the terminal, it performs the following processing:

[0015] 1. Determine whether the terminal is in class A or class B working status according to the synchronization status of the terminal and the server. On the server, there is one parameter A per terminal. When the terminal works in class A, the value of A is 0; when the terminal switches to work in class B mode, it will first synchronize with the server, and the server will update the value of parameter A to 1.

[0016] In this way, we can judge whether the terminal that needs to download data is in class A or class B working mode.

[0017] 2 If the terminal is in class A mode, store the data in the qu...

Abstract

The invention discloses a data downlink method compatible with CLASS A and CLASS B. When a server receives downlink data for a terminal, it judges whether it is in a class A or class B working mode according to the terminal state stored in the server. If it is class A, the downlink data will be stored in the queue, and then sent to the base station for transmission when the terminal next uplinks data; if it is class B, the next open downlink window of the terminal will be calculated according to the parameters of class B, and the data and The downlink window is immediately sent to the base station for transmission. The technical scheme of the invention can guarantee its randomness and safety. The present invention only exposes one interface to realize the downlink of two modes of class A and class B, simplifies the work of downlink data, and improves the efficiency of application access.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and relates to a data downlink method compatible with CLASS A and CLASS B, specifically, a LoRaWAN compatible data downlink method for CLASS A and CLASS B. Background technique [0002] LoRa is a low-power IoT technology proposed by Semtech, which is widely used in wireless meter reading and other fields. LoRaWAN uses LoRa technology to build a low-power wireless interconnection wide area network. The LoRaWAN terminal first sends the data to the base station through radio waves, and the base station then sends it to the LoRaWAN server through Ethernet for processing. The working modes of LoRaWAN terminals are divided into class A and class B. The difference between the two modes is mainly that the windows for terminals to receive downlink data are different. For terminals working in Class A mode, the window for receiving downlink data is opened 1 second after each uplink, and the...
