Description

Method, device and smart device for smart device network access

This application is based on the Chinese patent application with the application number of 202110119794.3 and the filing date of January 28, 2021, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is incorporated herein by reference.

technical field

The present application relates to the technical field of smart devices, for example, to a method, an apparatus, and a smart device for accessing a network of smart devices.

Background technique

The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc. It enables all intelligent devices that can be independently addressed to form an interconnected network. The existing NbIOT and LORAWAN communication technologies occupy half of the Internet of Things, and are widely used in smart devices that require low power, long distance, low speed, wide coverage, and multiple access. However, both NbIOT and LORAWAN network deployments are star networks, and such networks have many problems. For example, the entire network relies on a central node, and when the central node fails, the smart devices in the entire network will be unable to connect to the network. In practical applications, when there is a relatively remote network with few smart devices (such as townships, schools, etc.), the base station signal may be blocked by a building or a big tree, resulting in the inability of smart devices to access the network , affecting the user experience and business management of smart devices. If a smart device that cannot access the network is to restore the network connection, a base station must be established for the network separately, but this method increases a lot of network deployment costs.

In the prior art, by establishing a bluetooth mesh network and a wifi mesh local area network network, smart devices on the same floor or even in the same building can be connected, and data can be exchanged between smart devices, but the above communication methods cannot be targeted. Data communication between smart devices in a wide range.

For example, two consecutive operations or steps may, in fact, be performed substantially concurrently, or they may sometimes be performed in the reverse order, depending upon the functionality involved. Each block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, can be implemented in special purpose hardware-based systems that perform the specified functions or actions, or special purpose hardware implemented in combination with computer instructions.
