Problems solved by technology

In the prior art, when using the silent period parameter values ​​(Ni, mi, di) of the base stations for synchronization, each base station does not know precisely whether to readjust the parameters, which may easily cause unnecessary reselection, and if the silent period If the period scheduling information is lost during the transmission process, it will also affect the global silent period adjustment of the network, and the fault tolerance is poor

Abstract

The embodiment of the invention discloses a method for obtaining parameters of silent period. The method is characterized in that the method comprises the following steps: according to the current silent period parameters and expected silent period parameters adjusting the survival time value of the silent period parameters corresponding to the current silent period parameters; when the adjusted survival time value of the silent period parameters reach the expected activation value, setting the current silent period parameters as the expected silent period parameters and setting the survival time value of the silent period parameters as the original value. By using the invention, all base stations can adjust downward the silent period parameters according to different needs of base stations so as to finally realize that the silent period synchronous parameters of base stations in the same network can be adjusted downward.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for acquiring silent period parameters. Background technique [0002] With the development of radio technology, cognitive radio technology has been more and more widely used, and spectrum detection is cognitive radio technology to realize the use of existing allocated but often idle spectrum by the network. [0003] In order to improve the accuracy of spectrum detection, during the detection period, the IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.22 standard requires each base station to schedule a quiet period (quiet period, QP) to detect the spectrum being used, In order to avoid interference between base stations and make spectrum detection results more effective, IEEE 802.22 requires base stations to achieve synchronization of silent periods by exchanging silent period paramet...
