Strategy-based spectrum resource dynamic allocation method, device and system

Abstract

The invention relates to a strategy-based spectrum resource dynamic allocation method, device and system. The strategy-based spectrum resource dynamic allocation method comprises the following steps: summary processing node level spectral perception data and obtaining network level spectral perception data; according to spectrum management information and the network level spectral perception data, centrally controlling frequency spectrums through a common signal channel to obtain each spectrum management strategy; and carrying out spectrum resource allocation on spectrum-using equipment through a corresponding network general node according to each spectrum management strategy. The strategy-based spectrum resource dynamic allocation method enables the center of a frequency spectrum management framework to shift from the management center to the perception side of the spectrum-using equipment; and for the bounded perception result of a cognition user, by dynamically making a spectrum management strategy and sending the spectrum management strategy to the spectrum-using equipment, the spectrum-using equipment realizes dynamic spectrum access according to the given strategy, and spectrum decision is allowed to be made faster.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a strategy-based dynamic frequency spectrum resource allocation method, device and system. Background technique [0002] Traditional wireless communication systems adopt a static (fixed) spectrum allocation policy, that is, authorized users have exclusive rights to their spectrum, and other users are not allowed to use it. Although this spectrum allocation method is conducive to ensuring the service quality of the system, due to the imbalance of communication services in the time domain, region, and frequency domain, spectrum resources have not been fully utilized. With the rapid growth of demand for wireless communication services, wireless spectrum resources are increasingly scarce. [0003] Facing the complex electromagnetic environment, in recent years, people have proposed the concept of dynamic spectrum access and management in the application of spe...
