Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] The present invention realizes the "frequency demand-frequency assignment" dynamic spectrum management between the user and the spectrum service center through the short message interaction function of the Beidou communication module. The dynamic spectrum management system is established according to different regions, different networks or different departments. Each spectrum service center can operate independently or form a network for operation.

[0023] see figure 1 A dynamic spectrum management system shown includes two parts: a spectrum service center 1 and a frequency equipment client 2 . The spectrum service center 1 includes: a spectrum server 3 and a central wireless communication module 4 . The spectrum server 3 includes: dynamic spectrum management software and a spectrum service database. The frequency equipment that the client 2 connects to the...

Abstract

The invention relates to a dynamic spectrum management system including a spectrum service center and a frequency equipment client side. The spectrum service center includes a spectrum server and a center wireless communication module. The frequency equipment client side includes a control unit and a client wireless communication module. The frequency equipment is connected with the control unit, the control unit is embedded into the frequency equipment for real-time frequency conversion, and the control unit and the client wireless communication module are connected with each other, the client wireless communication module and the center wireless communication module realize signal transmission by satellite communication or other wireless channels, the center wireless communication module and the spectrum server are connected, and the spectrum server receives the data of the spectrum sensing network. The invention further provides a method of the dynamic spectrum management system. The dynamic spectrum management system can update the state of the effective spectrum pool in real time, dynamically assign the frequency points, optimize the utilization of spectrum resources, improve the utilization of frequency, and realize the combination of dynamic spectrum management and spectrum sensing.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a dynamic spectrum management system and method. [0002] technical background [0003] At present, frequency-using equipment mainly adopts fixed-frequency assignment. Once the frequency is assigned, it will be occupied for a long time, resulting in an irreconcilable contradiction formed by the increasingly tight spectrum resources on the one hand and the low utilization rate of the allocated spectrum on the other hand. In addition, there are still problems in the current frequency usage mode that frequency users and spectrum management are basically out of touch, and frequency assignment and spectrum sensing are also out of touch. Supported by spectrum sensing data in real time, mutual interference cannot be eliminated at the source of frequency assignment during frequency use. In addition, in the fixed frequency assignment method, once the frequency is assigned, ...
