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 and device for an Internet of Things application and a storage medium. The method comprises the following steps: receiving a downlink communication frequency automatically allocated by a cloud platform according to a near non-allocation similar frequency criterion; under the condition that a network access request sent by a second communication node is received, acquiring a communication key corresponding to the second communication node from the cloud platform according to the first communication protocol; under the condition that the communication key is legal, sending a network access success message and the communication key to the second communication node according to the downlink communication frequency; and dynamically allocating the communication parameters to the second communication node according to a preset allocation criterion. According to the embodiment of the invention, the communication parameters of the second communication node are dynamically allocated through cooperation among the first communication node, the second communication node and the cloud platform, so that the second communication node can be allocated to the optimal uplink communication frequency and uplink communication rate, bandwidth resources are fully utilized, and the communication efficiency is ensured.

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...
