A terminal automatic registration method of lpwan Internet of things

Abstract

The invention discloses a terminal automatic registration method of the LPWAN Internet of Things, which is characterized in that it comprises the following steps: 1) assigning frequency points of working channels to the ISM frequency band; 2) selecting some channels as default channels to form a default channel group ; 3) The base station side of the network configures working channels, including at least one default channel; 4) When the terminal side registers, it randomly selects one of the default channel groups to send a registration message, and can repeat it multiple times if it fails; 5) The network side receives After receiving the registration message of the terminal, the terminal is authenticated, and if successful, a registration acceptance message is returned to the terminal, carrying the indication of the working channel; 6) The terminal receives the registration acceptance message and obtains all working channels on the base station side. Beneficial effects achieved by the present invention: the method has made great progress, achieved the effect of fast terminal registration, saved power consumption in the terminal registration process, solved the problem of mutual interference when multiple networks coexist, and improved the network working channel notification efficiency.

Description

technical field [0001] The invention relates to a terminal automatic registration method of LPWAN Internet of Things, and belongs to the technical field of low-power wide-area Internet of Things communication. Background technique [0002] In the field of wireless communication technology, the communication parties must adopt the same frequency point and the same modulation method to communicate. Therefore, the terminal must obtain the working channel information of the network in order to adjust its own working channel parameters to the network working channel and carry out mutual communication. communication. [0003] For the LPWAN (Low Power Wide Area Network: Low Power Wide Area Internet of Things) Internet of Things, most networks work in the ISM frequency band, which requires the network not to occupy the channel for a long time to send broadcast information, so terminals cannot use the current PLMN before network access (Public Land Mobile Network: Public Land Mobile...

AI Technical Summary

Problems solved by technology

[0010] In order to solve the deficiencies of the existing technology, the purpose of the present invention is to provide a terminal automatic registration method of LPWAN Internet of Things, which solves the problem that the fixed frequency point method is not flexible enough to search the network or the full frequency point random transmission method consumes too much time. At the same time, it solves the problem of quick notification of a large number of network work channels
