Embodiment Construction

[0032] The technical solutions and other beneficial effects of the present invention will be apparent through the detailed description of specific embodiments of the present invention below in conjunction with the accompanying drawings.

[0033] The present invention divides the spectrogram model into multiple different sub-clusters through spectrogram segmentation, independently selects the cluster head and manages the sub-clusters through each sub-cluster, and then allocates spectrum.

[0034] see figure 1 , the frequency spectrum allocation method of the present invention comprises:

[0035] First step S1, constructing a spectrum graph model, obtaining available spectrum information and constructing a spectrum graph model according to the network topology;

[0036] The specific steps are as follows:

[0037] S11. Set the following attribute matrix for the available spectrum information: spectrum availability: A={a i，k |a i，k ∈ {0, 1}} N×M , which represents the availa...

Abstract

The invention discloses a method and a device for allocating frequency spectrum. The method comprises the following steps of: S1, acquiring available frequency spectrum information and constructing a spectrogram model according to network topology; S2, performing spectrogram segmenting on the spectrogram model and acquiring different clusters; S3, managing the clusters obtained by the spectrogram segmenting; and S4, calculating a frequency spectrum efficiency value of nodes of the clusters, and allocating the frequency spectrum to the nodes of the clusters according to the frequency spectrum efficiency value. According to the method and the device for allocating the frequency spectrum, the use ratio of the frequency spectrum resource reaches the maximum, the allocation of the frequency spectrum resource can be balanced, and the justification of the frequency spectrum resource use is improved.

Description

【Technical field】 [0001] The present invention relates to a spectrum allocation method and device, in particular to a spectrum allocation method and device. 【Background technique】 [0002] With the rapid development of society, economy and science and technology, the application fields of radio technology are becoming wider and wider, especially in the radio business of urban emergency response, subway, port and other departments, the demand for frequency resources is extremely urgent. At the same time, the research and development of various new technologies and the application of new services have rapidly increased the demand for frequency resources, and the shortage of radio frequencies has become a bottleneck restricting the development of radio communications. [0003] The traditional management of radio frequency spectrum adopts the method of fixedly allocating frequency spectrum, and authorizes users to use frequency spectrum. However, not all authorized users (autho...
