Abstract

A network access method and device of a same frequency terminal node, which is applied to a communication network, the method comprising: a same frequency terminal node sending, at a first frequency point, an access request message to a first gateway node; the same frequency terminal node receiving, at the first frequency point, an access response message returned by a target second gateway node, the target second gateway node being a second gateway node, determined by a server, that corresponds to the same frequency terminal node, and the access response message being generated by the server according to the access request message forwarded by the first gateway node.

Description

technical field

[0001] The present application relates to the field of communication technology, and in particular to a network access method for same-frequency terminal nodes, a network access device for same-frequency terminal nodes, a method for establishing a correspondence table, and a device for establishing a correspondence table. Background technique

[0002] LoRa network is a kind of low power wide area network LPWAN (Low Power Wide Area Network). The LoRa network includes: terminal nodes, LoRa gateway nodes (or LoRa base stations) and servers.

[0003] A network consisting of two types of LoRa inter-frequency gateway nodes interleaved and compatible with both LoRa inter-frequency terminal nodes and LoRa co-frequency terminal nodes can be called a LoRa mixed-frequency network. The inter-frequency gateway node refers to a gateway node that strictly distinguishes the uplink channel from the downlink channel. The frequency point of the uplink channel of the first typ...
