Problems solved by technology

[0007] 2. Through the way of transmission on the existing basic network, it needs to be carried on the existing network, which is highly dependent on the existing network
Due to the large amount of cognitive flow information in cognitive wireless networks, existing basic network services may be affected in this way
When the network is paralyzed, the cognitive flow, as important cognitive information in the cognitive wireless network, may not be transmitted in a timely and effective manner.
[0008] 3. There is no better solution for the transmission of cognitive flows between heterogeneous networks

Embodiment Construction

[0072] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0073] In an embodiment of the present invention, a device-to-device (Device-to-Device, D2D)-based solution for cognitive stream transmission between heterogeneous cognitive wireless networks is proposed.

[0074] Based on the cognitive radio technology, the present invention proposes a new method for transmitting cognitive information between heterogeneous wireless networks through a D2D border gateway in view of the low efficiency of cognitive information sharing and low spectrum utilization among existing heterogeneous networks. , to achieve efficient transmission of cognitive information between heterogeneous networks, realize seamless integration of heterogeneous cognitive wireless networks, and improve spectrum utilization efficiency.

Abstract

An embodiment of the invention provides a method, device and system for transmitting cognitive flows between heterogeneous cognitive radio networks. A D2D link exists between a first D2D border gateway and a second D2D border gateway, the first heterogeneous cognitive radio network is used for transmitting the cognitive flows to the first D2D border gateway, the first D2D border gateway is used for transmitting the cognitive flows to the second D2D border gateway based on the D2D link, and the second D2D border gateway is used for transmitting the cognitive flows to a cognitive flow receiving node of the second heterogeneous cognitive radio network. According to the method, device and system, cognitive information can be efficiently transmitted between the heterogeneous networks, and the frequency spectrum utilization efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of cognitive radio technologies, and more specifically, to a method, device and system for transmitting cognitive flows between heterogeneous cognitive wireless networks. Background technique [0002] Cognitive Radio (CR), as an intelligent spectrum access technology, can rely on spectrum sensing technology to detect the surrounding wireless communication environment, and obtain surrounding spectrum usage information according to certain learning and reasoning algorithms. The system working parameters are changed in real time through the software radio function, so as to achieve multi-dimensional spectrum multiplexing in time, spectrum and space, and improve spectrum utilization. Cognitive Nodes with cognitive radio capabilities perceive surrounding communication parameters, including cognitive information such as spectrum usage, power, and location distance of authorized users (Primary Users...
