CHANNEL BANDWIDTH SWITCHING METHOD AND NETWORK EQUIPMENT

摘要

Embodiments of the present invention provide a channel bandwidth switching method and network equipment. In the method, an MSE is acquired; a target bandwidth of a first space link is acquired according to the MSE and a correspondence between the target bandwidth of the space link and the MSE; in a case in which the signal has an interfering signal outside the operating bandwidth, the interfering signal is acquired; it is determined, according to the interfering signal and an error-free threshold, whether the operating bandwidth can be switched to the target bandwidth of the first space link; and if it is determined that the operating bandwidth can be switched to the target bandwidth of the first space link, information that carries the target bandwidth of the first space link is sent to the second network element, thereby avoiding a problem such as interruption of signal transmission.

1. A channel bandwidth switching method, comprising:
acquiring, by a first network element, a mean square error (MSE) used for identifying channel quality of a first space link from a second network element to the first network element; acquiring, according to the MSE and a correspondence between a target bandwidth of the first space link and the MSE, the target bandwidth of the first space link; acquiring a signal, which is received by the first network element, of the second network element in a case in which the target bandwidth of the first space link is greater than an operating bandwidth of the first network element; acquiring an interfering signal in a case in which the signal has the interfering signal outside the operating bandwidth; determining, according to the interfering signal and an error-free threshold, whether the operating bandwidth can be switched to the target bandwidth of the first space link; and if it is determined that the operating bandwidth can be switched to the target bandwidth of the first space link, sending information that carries the target bandwidth of the first space link to the second network element, so that a channel bandwidth of the first space link is switched from the operating bandwidth to the target bandwidth of the first space link.
