Embodiment Construction

[0027] 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 and embodiments.

[0028] Compared with the design technology of the traditional network system, the introduction of cognitive radio technology adds more degrees of freedom to the architecture design of the cognitive wireless network system, which is mainly reflected in three aspects: cognition, autonomy and adaptability. Changeability, while cognitive ability, autonomy and adaptability are quantitative descriptions of cognition, autonomy and adaptability, respectively. Among them, cognitive ability refers to the ability to acquire, express, transmit and utilize multi-domain environmental information; autonomous ability refers to the ability to make independent decisions and control with the goal of achieving overall effectiveness in a complex and changeable environme...

Abstract

The invention discloses an intelligent cognitive wireless network system for realizing heterogeneous network convergence. New function entities with multi-domain active cognition, high-efficiency heterogeneous network resource management, and network or terminal reconstruction are added in the network elements of the existing wireless network system, namely, a cognitive information management module, an intelligent management module and a heterogeneous network convergence management module are added on a network side; a reconstruction management unit, a united wireless resource management & self-optimization unit, a cognitive information/knowledge base and cognitive information management module are added on a terminal side; four interactive interfaces, namely interfaces among operators, interfaces between the network side and the terminal side, interfaces among respective modules and interfaces among units inside the modules are arranged. Modules or units inside the modules realize information exchange via interfaces, and realize corresponding network functions jointly, so that the cognitive capacity, autonomous capacity and adaptive capacity of the network are extended, the intellectualization of network management is promoted, the efficient utilization of heterogeneous network convergence and system frequency spectrum is realized, and overall performance of the network is promoted.

Description

technical field [0001] The present invention relates to cognitive radio technology, to be more precise, relates to an intelligent cognitive wireless network system that realizes the integration of heterogeneous networks, which is used to break through the limitations of existing network spectrum utilization and solve the spectrum utilization existing in existing networks It solves the problems of low efficiency and heterogeneity, effectively improves the utilization rate of network spectrum, and realizes the seamless integration of heterogeneous wireless networks, which belongs to the technical field of network structure of the network layer of wireless communication systems. Background technique [0002] The emergence of cognitive radio technology relieves the pressure of low spectrum utilization in existing networks. At present, some researches have been done on the cognitive wireless network system. A few typical scenarios are briefly described below: [0003] see figu...
