Short-distance communication method, system and device based on NB-LOT network and storage medium

Abstract

The invention discloses a short-distance communication method, system and device based on an NB-LOT network and a storage medium, and the method comprises the steps: detecting all terminal devices inthe NB-IoT network, and carrying out the networking of the terminal devices; reading the signal intensity of the terminal equipment in the NB-IoT network, and establishing a signal intensity list; sending data through a first terminal device by using the NB-IoT network and selecting a second terminal device as a relay route when the data sending fails; and forwarding the data to be sent by the first terminal device through the second terminal device. According to the invention, networking is carried out on the application terminals in the NB-IoT network, the optimal relay interaction channel is established according to the signal intensity, and when the terminal device fails to send data smoothly, other terminal devices are used as relay routes to complete data sending. The situation thatthe data of the terminal equipment fails to be sent due to signal coverage is avoided. The short-distance communication method, system and device based on the NB-LOT network and the storage medium canbe widely applied to the technical field of indoor NBIOT communication.

Description

technical field [0001] The present invention relates to the technical field of indoor NB-IOT communication, in particular to a short-distance communication method, system, device and storage medium based on NB-LOT network. Background technique [0002] Nowadays, the application trend of the Internet of Things is gradually accelerating, and the supporting communication requirements are gradually increasing. As an important branch of the Internet of Things application, NB-IoT network is widely used because of its low power consumption operation advantages. With the basic completion of NB-IoT network coverage at this stage, the number of indoor use scenarios and corresponding application terminals based on NB-IoT networks is gradually increasing. However, in the face of complex indoor scenarios, the network often has coverage blind spots, which leads to the fact that not all applications All terminals can successfully complete data interaction, but some application terminals ar...

With the basic completion of NB-IoT network coverage at this stage, the number of indoor use scenarios and corresponding application terminals based on NB-IoT networks is gradually increasing. However, in the face of complex indoor scenarios, the network often has coverage blind spots, which leads to the fact that not all applications All terminals can successfully complete data interaction, and some application terminals often cannot successfully complete data uplink and downlink tasks due to poor NBIOT network signal coverage
