Problems solved by technology

If the frequency band used by the cognitive system is unstable or unreliable, this spectrum will be frequently requisitioned by the authorized system, which will cause a large number of users to switch frequently in the cell using this spectrum, and even cause call drop

Embodiment 1

[0144] like Figure 8 As shown, it is a schematic flowchart of the first cognitive system allocation method provided by the embodiment of the present invention, including the following steps:

[0145] S801. Obtain a set of idle spectrum units detected and reported by the cognitive system cell;

[0146] S802. Perform spectrum negotiation with all cognitive system cells that request spectrum, delete idle spectrum units in the set of idle spectrum units that cause interference to other cognitive system cells that have allocated spectrum resources, and form the remaining idle spectrum units into An optional collection of spectral units.

[0147] According to steps S801 and S802, a set of optional spectrum units allocated to the cognitive system cell requesting spectrum resources can be obtained.

[0148] S803. Determine the reliability of each optional spectral unit in the cognitive system according to the use characteristic information of each optional spectral unit in the set ...

Embodiment 2

[0157] like Figure 9 As shown, it is a schematic flowchart of the second cognitive system allocation method provided by the embodiment of the present invention, including the following steps:

[0158] S901. Obtain a set of idle spectrum units detected and reported by the cognitive system cell;

[0159] S902. Perform spectrum negotiation with all cognitive system cells requesting spectrum, delete idle spectrum units in the set of idle spectrum units that cause interference to other cognitive system cells that have allocated spectrum resources, and form the remaining idle spectrum units into An optional collection of spectral units.

[0160] According to steps S901 and S902, a set of optional spectrum units allocated to the cognitive system cell requesting spectrum resources can be obtained.

[0161] S903. Determine the reliability of each optional spectral unit in the cognitive system according to the use characteristic information of each optional spectral unit in the set o...

Abstract

The invention relates to a radio communication technique, in particular to a cognitive system cell spectrum allocation method, and provides a cognitive system cell spectrum allocation method, a device and a system, which are used to enhance the stability of a cognitive system. The spectrum allocation technique provided by the embodiment of the invention takes the reliability of spectrum into fullconsideration, enhances the stability of the cognitive system and gives consideration to reliability and continuity at the same time during spectrum allocation, consequently, the system can reliably use spectrum, the frequency-switching frequency of the cognitive system is effectively reduced, meanwhile, the continuity of the allocated spectrum is ensured as much as possible, the increase of system overhead is avoided, and the spectrum-utilizing rate is increased.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a frequency spectrum allocation technology of a cognitive system cell. Background technique [0002] With the development of wireless communication technology and the expansion of its application fields, spectrum resources are becoming increasingly scarce, which has become a problem that the wireless communication research field and operators have to face. However, studies by relevant agencies in various countries have shown that the irrational use of spectrum by various wireless access technologies is the essential cause of spectrum scarcity. Waste of resources and overcrowding of unlicensed frequency bands. [0003] At present, cognitive radio technology is considered to be the best solution to solve the "scarce" problem of spectrum and improve spectrum utilization. By detecting other licensed frequency bands, the cognitive radio system obtains information about idle spect...
