Communication method between LoraWan network and client server

Abstract

The invention relates to a communication method between a LoraWan network and a client server. According to the invention, the client server adds a priority to a current packet to be sent before sending the packet, and then sends the current packet to a LoraWan server; after receiving the current packet, the LoraWan server determines the queue length of a cache queue; if the queue is full, a command that the queue is full is sent to the client server; and if the queue is not full, the current packet is inserted into the cache queue and is sorted by priority, and the packet with the highest priority is sent. If receiving the command that the queue is full sent by the LoraWan server, the client server sends a queue length query command to the LoraWan server at a preset time; and if the queuelength is less than a preset threshold, the current packet is sent again. If the client server does not receive a command that the packet is properly voted sent by the LoraWan server within a presettime, the client server sends a packet deleting command to the LoraWan server. By means of the communication method between the LoraWan network and the client server, different service quality can beprovided for different services.

Description

technical field [0001] The invention relates to a communication method, in particular to a communication method between a LoraWan network and a client server. Background technique [0002] With the continuous development and extension of the Internet, as well as the development of communication technology, big data and other related supporting technologies, the Internet, which was previously connected by people and people, people and machines, and machines and machines, has extended to information exchange between any object. Internet of Things. Among them, LoraWan, as a solution for the Internet of Things, has been applied in many countries and regions, and has a broad prospect. [0003] As a type of LPWAN, LoraWan's main advantages are low power consumption and long distance, but the disadvantage is that the speed is low. In the case of high node density and frequent uplink and downlink data interactions, it is easy to cause communication congestion, resulting in data pac...

Problems solved by technology

[0003] As a type of LPWAN, LoraWan's main advantages are low power consumption and long distance, but the disadvantage is that the speed is low. In the case of high node density and frequent uplink and downlink data interactions, it is easy to cause communication congestion, resulting in data packets not being uplinked in time. downlink

In practical applications, different applications have different sensitivity to congestion due to different business types.
