Embodiment approach
[0067] As a preferred implementation, the weight threshold is determined by the following method:
[0068] Obtain the proportion of the current dedicated network gateway device;
[0069] If the proportion is less than or equal to 5%, the weight threshold is set to 0;
[0070] If the proportion is greater than or equal to 10%, the weight threshold is set to 1;
[0071] If the proportion is greater than 5% and less than 10%, the weight threshold is generated according to the probability.
[0072] In this embodiment, there is also dynamic adjustment and control for the weight threshold, and the weight threshold is dynamically set according to the number of gateway devices in the private network, which can adjust the number of gateway devices in the private network to prevent excessive consumption of the generated network and excessive Less link complexity leading to point-to-point communication is too high.
[0073] As a preferred implementation manner, the construction of the...

The invention belongs to the technical field of communication, and particularly relates to a LoRa-based public and private network intercommunication talkback method, device and system, and the method comprises the steps: determining whether a node is gateway equipment or not according to a preset dynamic gateway generation rule, and carrying out the broadcasting of the gateway equipment to a private network; if the node is gateway equipment and receives the public network talkback data, converting the received talkback data; constructing talkback links from the node to a target node, and determining resource consumption of each talkback link; determining an optimal link according to the resource consumption of each link; and transmitting the converted talkback data to the next node of the optimal link according to the optimal link. According to the method provided by the invention, public network talkback and private network talkback are combined, and meanwhile, the problems of long-distance transmission and no network coverage are solved; by dynamically generating the gateway node and screening the talkback link according to the resource consumption, the resource consumption of the private network for transmitting the point-to-point talkback data can be reduced, and the data delay is reduced.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a LoRa-based public and private network intercommunication intercom method, device and system. Background technique [0002] With the vigorous development of all walks of life, the application of walkie-talkies is becoming more and more extensive. The walkie-talkie is mainly used for communication and command and dispatch among group members, so as to improve communication efficiency and improve the rapid response ability to deal with emergencies. As the walkie-talkie enters the civilian market, people begin to use it more and more, and the requirements for the performance of the walkie-talkie, such as voice transmission distance and voice quality, are getting higher and higher. [0003] At present, there are two main types of walkie-talkies: private network walkie-talkies and public network walkie-talkies. [0004] Traditional private network intercoms includ...
