Subsystem ID construction method and networking application

Abstract

The invention discloses a subsystem ID construction method and a networking application. The subsystem ID construction method comprises the steps: equally dividing a system ID into N segments of sequences, and enabling the length of each segment to be M; scrambling the N sections of sequences respectively to obtain N scrambling sequences with the length of M * N_SUBSYSTEM, wherein the N_SUBSYSTEMis the number of subsystems; preprocessing the N scrambling sequences to obtain a to-be-allocated sequence with the length of M * N_SUBSYSTEM; and dividing the sequence to be allocated into N_SUBSYSTEM sub-sequences, wherein each sub-sequence is a subsystem ID. Based on the subsystem ID construction method, the invention discloses an IOT networking structure which comprises a network of a three-layer structure. The private IOT networking structure comprises a subsystem, and a roaming networking deployment method among multiple IOT systems, wherein each IOT system is provided with an IOT of a first-layer structure using the same carrier, and the IOT of each system adopts the same subsystem ID. According to the subsystem ID construction method, the same-frequency networking of the IOT, the non-blind area coverage of the IOT and the switching of the equipment among multiple systems can be realized.

Description

technical field [0001] The invention relates to a networking method of the Internet of Things, in particular to a method for constructing a subsystem ID and a networking application. Background technique [0002] Since the concept of the Internet of Things (IoT) was proposed at the end of the 20th century, its technology and application fields have been continuously enriched and improved. Provides good support. [0003] As an Internet-based Internet of Things technology, the Internet of Things has played a good role in promoting the construction of efficient production and intelligent facilities. However, the Internet of Things based on wireless Internet communication technology is highly restricted by limited communication frequency bands with the expansion of the network and the increasing number of access terminals. For the Internet of Things under the unlicensed spectrum, it can only use limited frequency band carriers, which limits the coverage of the Internet of Thin...

Problems solved by technology

However, with the expansion of the network and the increasing number of access terminals, the Internet of Things based on wireless Internet communication technology is highly restricted by the limited communication frequency band.

For the Internet of Things under the unlicensed spectrum, it can only use limited frequency band carriers, which limits the coverage of the Internet of Things to a large extent

However, direct multiplexing of carriers will cause co-channel interference in the network.
