Embodiment 1

[0043]In order to solve the problems that the traditional dynamic spectrum allocation has high requirements on the reliability of the transmission link, prone to frequency conflicts and poor invulnerability, the present invention provides a policy-based dynamic allocation of spectrum resources implemented from the perspective of the network central node Method embodiment 1; figure 1 It is a schematic flow diagram of embodiment 1 of the policy-based spectrum resource dynamic allocation method implemented from the perspective of the network central node in the present invention; as figure 1 As shown, the following steps may be included:

[0044] Step S110: When the wireless communication network perceives that there is an inter-network spectrum conflict, perform inter-network spectrum coordination through a public channel, and obtain an inter-network coordination result;

[0045] Step S120: Based on the results of the inter-network coordination, the spectrum is centrally manage...

Embodiment 2

[0143] In order to solve the problems that traditional dynamic spectrum allocation requires too high reliability of transmission links, frequent frequency conflicts, and poor invulnerability, and at the same time further describe the technical scheme of the strategy-based dynamic spectrum resource allocation system of the present invention, the present invention Embodiment 2 of a strategy-based dynamic spectrum resource allocation system is also provided; compared with the above-mentioned embodiment 1, the policy-based spectrum resource dynamic allocation system embodiment 2 may include a first-level network center node and several second-level The central node of the network, so that the spectrum coordination between the networks only needs to be in each wireless communication network (secondary network) where the spectrum conflicts, and the coordinator conducts interactive negotiation on the division and use of the spectrum, and the (first-level) network central node adjusts t...

Abstract

The present invention relates to a strategy-based dynamic spectrum resource allocation method, device and system, wherein the policy-based spectrum resource dynamic allocation method includes the following steps: summarizing and processing node-level spectrum sensing data to obtain network-level spectrum sensing data; Management information and network-level spectrum sensing data are used to centrally control the spectrum through the public channel to obtain various spectrum management strategies; the general nodes of the network allocate the spectrum resources of the frequency-using equipment according to each spectrum management strategy. The present invention shifts the focus of the spectrum management architecture from the management center to the perception side of the frequency-using equipment through a strategy-based method, and aims at the limited perception results of the cognitive users, dynamically formulates spectrum management strategies and sends them to the frequency-using equipment, and uses the frequency-using equipment Perform dynamic spectrum access according to a given strategy to make spectrum decisions more quickly.

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...
