Method, device and system for sharing spectrum resource among wireless systems

Abstract

The invention discloses a method, a device and a system for sharing a spectrum resource among wireless systems, which are used for achieving spectrum share between an authorized system and an unauthorized system in the application scene of unauthorized system wide-range networking. The method comprises the following steps of: receiving statistical information of an available frequency band of the unauthorized system, wherein the statistical information of the available frequency band is determined according to the use information of a frequency band of the authorized system, and includes the information of the available frequency band, region information corresponding to the region of the available frequency band and time information corresponding to the time of the available frequency band; determining an available carrier cluster of a base station in the region corresponding to the region information in a time period corresponding to the time information according to the available frequency band information; and according to the preset allocation policy, determining target carrier allocated to each section included in the base station in the region corresponding to the region information from the carrier included in the available carrier cluster.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for sharing frequency spectrum resources between wireless systems. Background technique [0002] The wireless communication network is currently developing in the direction of broadbandization, heterogeneity, and all-IP (Internet Protocol, Internet Protocol). The contradiction between users' increasing wireless communication needs and limited wireless spectrum resources continues to increase. However, studies have shown that the spectrum resources suitable for wireless communication are very scarce on the one hand, and some frequency bands are very tight, such as mobile communication frequencies; There is a serious imbalance in wireless spectrum utilization, and the overall efficiency of spectrum use is low. Therefore, the prior art proposes a spectrum sharing technology, hoping to enable wireless application systems with tight...

Problems solved by technology

However, the network area of ​​the entire cellular mobile communication network covers a large area. In the entire network area, the idle frequency band of the authorized system may vary greatly with different geographical locations, making the available frequency bands of each cell of the cellular mobile communication network incomplete. The same, therefore, the existing spectrum sharing technology is not suitable for the application scenario of large-scale networking of unlicensed systems

[0005] From the above analysis, it can be seen that how to realize the sharing of spectrum resources between the licensed system with low spectrum utilization rate and the unlicensed system with high spectrum utilization rate in a large-scale network has become one of the technical problems to be solved urgently in the existing technology.
