Embodiment 1

[0103] The embodiment of the present invention provides a communication method, the method is applied to the first LoRa terminal, image 3 A schematic flowchart of a communication method provided by an embodiment of the present invention, such as image 3 As shown, the method mainly includes the following steps:

[0104] Step 301, receiving a downlink signal sent by a first upper-level network device; wherein, the downlink signal includes a target terminal identifier and an operation instruction for instructing the target terminal to operate; the first upper-level network device includes a LoRa gateway, or A second LoRa terminal that is closer to the LoRa gateway than the first LoRa terminal;

[0105] Step 302, determine whether the first LoRa terminal itself is the target terminal according to the downlink signal;

[0106] Step 303, corresponding to determining that the first LoRa terminal itself is the target terminal, executing the operation instruction in the downlink si...

Embodiment 2

[0157] The embodiment of the present invention provides to realize a kind of communication method, and described method is applied to LoRa gateway, Figure 6 A schematic flowchart of a communication method provided by an embodiment of the present invention, such as Figure 6 As shown, the method mainly includes the following steps:

[0158] Step 601, from the LoRa terminals under the jurisdiction of the LoRa gateway itself, determine the LoRa terminal with the highest order according to the preset sorting strategy;

[0159] Step 602, generating a downlink signal; wherein, the downlink signal includes a target terminal identifier and an operation instruction for instructing the target terminal to operate;

[0160] Step 603, sending the downlink signal to the LoRa terminal with the highest order.

[0161] for Figure 6 In the technical solution shown in step 601, from the LoRa terminals under the jurisdiction of the LoRa gateway itself, the LoRa terminal with the highest orde...

Embodiment 3

[0179] The embodiment of the present invention implements a communication method, Figure 8 A schematic diagram of a communication method provided by an embodiment of the present invention, such as Figure 8 As shown, the method mainly includes the following steps:

[0180] Step 801, the LoRa gateway sends a signal S1 to the LoRa terminal 1, wherein the signal S1 includes the LoRa destination terminal address, the signal transmission end identification and the operation instruction, wherein the signal transmission end identification is used to judge whether the LoRa terminal currently receiving the signal is a LoRa terminal If the destination terminal is judged to be the address of the LoRa destination terminal, the signal transmission process is ended.

[0181] Here, the signal S1 belongs to the downlink signal sent by the LoRa gateway to the LoRa terminal.

[0182] It should be noted that the signal transmission end identification can be the only identification that the Lo...

Abstract

The embodiment of the invention relates to the Internet of Things technology, and discloses a communication method and device, a terminal, a gateway and a computer storage medium, the method comprising: receiving a downlink signal sent by a first superior network device; wherein the downlink signal comprises a target terminal identifier and an operation instruction for indicating the target terminal to operate; wherein the first superior network device comprises a LoRa gateway or a second LoRa terminal closer to the LoRa gateway than the first LoRa terminal; determining whether the first LoRaterminal is the target terminal or not according to the downlink signal; correspondingly determining that the first LoRa terminal is the target terminal, and executing the operation instruction in thedownlink signal; and correspondingly determining that the first LoRa terminal is not the target terminal, forwarding the downlink signal to a third LoRa terminal which is farther from the LoRa gateway than the first LoRa terminal.

Description

technical field [0001] Embodiments of the present invention relate to Internet of Things technologies, and in particular to a communication method, device, terminal, gateway, and computer storage medium. Background technique [0002] With the continuous development of the Internet of Things technology, the quality of life is increasing, and people's demand for intelligent experience is also increasing. The application of various traditional communication transmission technologies in various Internet of Things industries is gradually unable to meet people's needs. 2.4GHz WiFi, Bluetooth, Zigbee and other traditional communication technologies, as well as traditional wide area network technology 2G / 3G / 4G and other wireless technologies, although they can realize the network interconnection and communication of various terminal devices, they cannot take into account both long-distance transmission and low power consumption. consumption transmission. [0003] Until the emergenc...
