A low-power communication system based on IoT gateway

Abstract

The invention relates to a low-power-consumption communication system based on an Internet-of-Things gateway. The communication system comprises a forwarding server, a communication base station, a core network, an Internet-of-Things gateway and a mobile terminal. The forwarding server is connected with the core network; the core network is connected with the forwarding server and the communication base station; the communication base station is connected with the core network in a wired communication mode and is connected with the Internet-of-Things gateway in a wireless communication mode; the Internet-of-Things gateway is connected with the communication base station and the mobile terminal in a wireless communication mode. According to the invention, the workload of the communication base station is greatly reduced, so that the purpose that large-scale Internet-of-Things mobile terminals are accessed to the Internet-of-Things at the same time is achieved. The mobile terminal performs short-distance communication with the Internet-of-Things gateway by adopting the Internet-of-Things wireless communication protocol, and the mobile terminal is not directly connected with the communication base station, so that the low power consumption characteristic of the terminal equipment is maintained while the communication reliability of the mobile terminal is ensured.

Description

technical field [0001] The invention relates to a method for a wireless communication terminal to access a network, in particular to a method for allowing wireless communication terminals of a large-scale Internet of Things to simultaneously access the Internet of Things. Background technique [0002] With the arrival of the 5G era, the entire communication field is striving to achieve the goal of "Internet of Everything". It wants to transform information into action through the Internet of Everything, create new functions for enterprises, individuals and countries, and bring richer experiences and unprecedented economic development opportunities. [0003] In the field of the Internet of Things, the current mainstream wireless large-scale connection communication protocols (Internet of Things terminal network access solutions) are NB-IoT, LoRaWAN and Sigfox. The base station capacity of NB-IoT technology can theoretically reach 50,000, but the actual measurement can only r...

AI Technical Summary

Problems solved by technology

The base station capacity of NB-IoT technology can theoretically reach 50,000, but the actual measurement can only reach 3,000 to 5,000; LoRaWAN and NB-IoT have similar design ideas and working principles, so their base station capacities are also similar, and they cannot Realize simultaneous access of large-scale IoT terminals

Sigfox has the widest coverage among the above three technical solutions, with a base station capacity of hundreds of thousands, but in order to achieve hundreds of thousands of base station capacity, it limits the bandwidth of terminal equipment to 100bps, and limits the daily communication of terminal equipment The number of times does not exceed 140, which limits the application scenarios of Sigfox

To sum up, there is currently no technical solution that can realize large-scale Internet of Things terminal devices to access the Internet of Things at the same time, while allowing the terminal devices to maintain the characteristics of low power consumption, high reliability, low cost and small size
