Problems solved by technology

[0002] In engineering applications, if a large number of terminal devices receive or send data in the same frequency band in a similar time in a LoRaWAN network, it will cause mutual interference and affect the communication effect
If you manually configure communication-related parameters such as frequency and rate for each terminal device during project deployment, it will take a lot of manpower
Moreover, due to the complexity of the on-site situation, it is impossible to accurately find the best affiliation relationship between the device and the gateway

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0037] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

[0038] In the LoRaWAN protocol, the network access methods of the second communication node (ie, the terminal device) include two modes: Over-The-Air Activation (OTAA) mode and Activation By Personalization (ABP) mode. Among them, OTAA mode: after the terminal device is deployed or di...

Abstract

The invention discloses a parameter distribution method, device and storage medium for Internet of Things applications. The method includes: receiving the downlink communication frequency automatically allocated by the cloud platform according to the criterion of not allocating similar frequencies in proximity; when receiving the network access request sent by the second communication node, obtaining the corresponding frequency of the second communication node from the cloud platform according to the first communication protocol. the communication key; if the communication key is valid, send the network access success message and the communication key to the second communication node according to the downlink communication frequency; and dynamically allocate communication parameters to the second communication node according to the preset allocation criteria. In the embodiment of the present invention, through the cooperation between the first communication node, the second communication node and the cloud platform, the communication parameters of the second communication node are dynamically allocated, so that the second communication node can be allocated the best uplink communication frequency and The uplink communication rate makes full use of bandwidth resources and ensures communication efficiency.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a parameter allocation method, device and storage medium for Internet of Things applications. Background technique [0002] In engineering applications, if a large number of terminal devices receive or send data in the same frequency band in a similar time in a LoRaWAN network, it will cause mutual interference and affect the communication effect. If during project deployment, manually configure communication-related parameters such as frequency and rate for each terminal device, it will take a lot of manpower. Moreover, due to the complexity of the on-site situation, it is impossible to accurately find the best affiliation relationship between the device and the gateway. Contents of the invention [0003] In view of this, the present invention provides a parameter allocation method, equipment and storage medium for Internet of Things applications, which...
