Radio frequency rapid frequency sweeping network access method suitable for G3 standard dual-mode communication

The invention relates to a radio frequency rapid frequency sweeping network access method for G3 standard dual-mode communication. The method comprises the following steps: periodically sending a first message in a public frequency band at a terminal with radio frequency and PLC successful network access, wherein the first message comprises a network identifier and radio frequency working frequency band information; and a terminal which does not access the network initiates a network access process at the PLC and the radio frequency simultaneously, monitors the public frequency band to obtain the network identifier and the working frequency band information, and tries to access the network according to the network identifier and the working frequency band information. And if the PLC successfully accesses the network firstly, the terminal obtains the network identifier through the PLC and completes radio frequency network access according to the message information in the public frequency band. The method and
