Abstract

The invention discloses a dynamic spectrum distributing method and device based on information channel management. The dynamic spectrum distributing method and device based on information channel management is used for solving the technical problems that time delay of spectrum distribution in spectrum resource reconfiguration is long, overall performance and spectrum utilization efficiency of spectrum resource reconfiguration are low. The method includes the steps that a network node generates an information channel set according to a usable information channel list and information channel classifying information, and maintains and updates the information channel set ; the network node selects spectrums from the information channel set and conducts spectrum distribution; the usable channel information list is obtained from a database through the network node; the information channel classifying information comprises following one item or multiple items, namely, a channel information quality condition, information channel idle time, information channel sending parameter limitation, information channel geographical isolation degree and channel information spectrum frequency. By the adoption of the dynamic spectrum distributing method and device based on information channel management, the time delay of the spectrum resource reconfiguration of a wireless system spectrum can be lowered, the overall performance of spectrum resource reconfiguration is improved, and spectrum utilization efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication and cognitive radio, and more specifically, to a method and device for dynamic frequency spectrum allocation based on channel management. Background technique [0002] In a cognitive radio (Cognitive Radio, CR) system, wireless communication devices with cognitive functions can use the licensed frequency band in a "opportunistic" way. The spectrum utilization rate is improved, and the contradiction between the increasing demand for wireless services and the increasingly scarce spectrum resources is resolved. CR technology breaks the fixed spectrum allocation system in the traditional sense, dynamically allocates spectrum among systems, and improves spectrum utilization efficiency. As one of the core technologies of cognitive radio, dynamic spectrum allocation technology has become a research hotspot. [0003] In cognitive radio, wireless resource management can be improved...
