Node network access method, device and equipment and readable storage medium

Abstract

The embodiment of the invention provides a node network access method, a device and equipment and a readable storage medium, a first node searches a second node in network nodes and sends network access request information to the second node, the second node obtains network access response information according to the network access request information after receiving the network access request information sent by the first node, and sends the network access response information to the first node, the first node accesses the network according to the network access response information. The first condition comprises that being adjacent to the first node, the depth is smaller than or equal to a preset value, a remaining address exists in a hierarchy to which a sub-node in the reserved address space belongs, the network access request information comprises information of a node to be accessed, and the node to be accessed comprises the first node and at least one descendant node of the first node; the information of any one to-be-accessed node indicates the relationship between the to-be-accessed node and other to-be-accessed nodes. Through signaling interaction between the first node and the second node, the network access of at least two nodes is realized, the network signaling overhead is reduced, and the network access speed is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method, apparatus, device, and readable storage medium for a node to access a network. Background technique [0002] Tree topology is a commonly used topology in ad hoc networks with a fixed center. Because of its clear parent-child node relationship, tree topology is widely used in the Internet of Things because it requires very little cost for route maintenance. [0003] In a tree topology, when a node is disconnected from its parent node, the node needs to re-select the parent node, and the node's child nodes and descendant child nodes (collectively referred to as descendant nodes) also need to re-select the parent node to re-enter the network, and a large number of nodes re-enter the network When the route switching is slow and the signaling overhead is large, it is easy to cause service delay and network congestion. [0004] Therefore, it is necess...
