5G wide-area IoT architecture based on mobile piggybacking and data transmission method thereof

Abstract

The invention provides a 5G wide-area IoT architecture based on mobile piggybacking and a data transmission method thereof. The architecture comprises a ground terminal, a mobile forwarding node, a network access node and a core network, wherein terminal is connected with the forwarding node through a low-power wireless interface, the forwarding node is connected with the network access node through a high-speed wireless link, and the network access node is connected to the core network through an optical fiber. According to the invention, the forwarding node with mobility is used for realizing data transmission, when the node passes by the vicinity of the terminal, information to be sent by the terminal is collected to a buffer area of the node, and the information is stored all the time in the moving process; and when the node arrives the vicinity of the base station, the terminal service is transmitted to the access node to realize data network access. According to the invention, the problems of power consumption overhead, deployment cost and massive user access based on the existing network architecture can be improved; the problems of high layout cost, insufficient coverage range, high operation cost and the like of the existing 5G network for massive terminal network access are solved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication architecture, and in particular relates to a 5G wide-area Internet of Things network architecture based on a mobile broadband and a data transmission method thereof. Background technique [0002] As the main development direction of the new generation of information and communication technology, 5G will open a new era of digitalization of the Internet of Everything. It is of great strategic significance to build a network power, build a smart society, develop a digital economy, and achieve high-quality economic development in my country. Statistics show that the communication between people only accounts for about 20% of the total applications, while 80% of the applications are communication between things. Mobile communication is changing from the connection between people to people Connect with things and things with things. With the maturity of the Internet of Things technology,...

Problems solved by technology

[0004] In order to overcome the problem of small base station coverage in the traditional network architecture, wide-area coverage can only be achieved by increasing the deployment density of base stations. As a result, the existing 5G network has high deployment costs, insufficient coverage, and high operating power consumption for massive
