Problems solved by technology

In the prior art, when using the silent period parameter values ​​(Ni, mi, di) of the base station for synchronization, each base station does not know precisely whether to readjust each parameter, 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

Embodiment 1

[0126] Figure 5 It is a schematic structural diagram of the first embodiment of the system of the present invention, and the first embodiment of the system of the present invention includes:

[0127] The first base station 1 is configured to obtain silent period scheduling information according to the current silent period parameter value and the expected silent period parameter value, and send the silent period scheduling information to the second base station 2;

[0128] The silent period scheduling information includes a silent period parameter value and a silent period parameter survival time value corresponding to the silent period parameter value;

[0129] The second base station 2 is configured to receive the silent period scheduling information sent by the first base station 1 , and adjust its own silent period parameters according to the silent period scheduling information of the first base station 1 .

[0130] Wherein, the first base station 1 includes means for a...

Abstract

A method, apparatus for obtaining quiet period parameters and system thereof, wherein the method includes: valid time length values of the quiet period parameters corresponding to current quiet period parameter values are adjusted according to the current quiet period parameter values and expected quiet period parameter values, the current quiet period parameter values are set to be the expected quiet period parameter values and the valid time length values of the quiet period parameters are set to be initial values when adjusted valid time length values of the quiet period parameters reach preset trigger values. With the application of the present invention, each base station can reduce the quiet period parameter values according to self requirement and quiet period synchronization parameters of base stations in the same network can be reduced finally.

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, IEEE802.22 requires base stations to achieve synchronization of silent periods by exchanging silent period paramet...
