AI Technical Summary

Problems solved by technology

Heterogeneous integration and multi-hop relay are generally considered to be the characteristics of future networks. However, due to the relative independence and autonomy of heterogeneous networks, there is no effective coordination mechanism between them, resulting in interference between systems, overlapping coverage, and limited service provision capabilities of a single network. Problems such as scarcity of spectrum resources and seamless switching of services cannot be solved

Embodiment Construction

[0021] Exemplary embodiments of the present application are described in detail with reference to the accompanying drawings.

[0022] figure 1 Shown is a centralized cognitive network system 1000 with cognitive capabilities according to one embodiment of the present application. As shown in the figure, the system 1000 includes multiple iNodes 10 - 1 , 10 - 2 , 10 - 3 , 10 - 4 , . . . , Root-iNode 20 and CN-OAM subsystem 30 .

[0023] Each iNode is used to perceive the relevant information of the cell under its jurisdiction, such as which network coverage is currently available in the area, the current congestion level of these networks, and so on. In addition, the learning unit 230 of each iNode also has a learning ability, which is used to learn the topology information, network flow information and physical information of the current network from the Root-iNode 20 and the CN-OAM subsystem 30, and the learned information can be used for all The analysis of the network statu...

Abstract

The invention discloses a centralized cognitive network system with cognitive capabilities and a distributed cognitive network system with cognitive capabilities. The centralized cognitive network system comprises at least one iNode for sensing network information of jurisdiction area thereof; a Root-iNote for receiving the network information and respectively establishing a configuration access plan for each iNode according to the network information; a CN (communicating net)- OAM (operation administration and maintenance) subsystem for obtaining the configuration access plan from the Root-iNote and respectively building communication link with related iNode based on the configuration access plan, wherein the communication link based on the iNode downloads related configuration parameters from the CN-OAM subsystem so as to perform self-configuration by use of the configuring parameters.

Description

technical field [0001] This application relates to centralized and distributed wireless cognitive network systems in the field of communication technology. Background technique [0002] The seamless cognitive mode is the best solution to solve the limited spectrum resources and the current extremely low spectrum utilization. By intelligently and dynamically recognizing the spectrum usage status of surrounding communication devices, a reasonable competition / cooperation strategy is adopted to meet the requirements of maximizing spectrum usage efficiency and system performance. A cognitive network with intelligent learning capabilities can most harmoniously integrate existing cellular networks and unlicensed band networks such as Ad-hoc, Mesh, and WiFi, and make future intelligent Multi-mode terminals can seamlessly switch between various communication technologies, providing users with a truly ubiquitous, personalized, universally aware and adaptable business environment.
