Method, device, and system for processing communications system signal

摘要

The present invention provides a method, a device, and a system for processing a communications system signal. The method includes: acquiring, by a communications system of a first standard, a first message, where the first message carries a signal strength, sent by a communications system of a second standard, on a frequency where interference of the communications system of the second standard on the communications system of the first standard exists; and performing, by the communications system of the first standard, according to the signal strength, filtering processing for a signal to be processed of the communications system of the first standard. In embodiments of the present invention, interference can be reduced and receiving performance can be improved.

1. A method comprising:
acquiring, by a communications system of a first standard, a message sent by a communications system of a second standard to the communications system of the first standard on a frequency where interference of the communications system of the second standard on the communications system of the first standard exists, the message including an indication of signal strength detected by the communications system of the second standard; and performing, by the communications system of the first standard, according to the indication of the signal strength included in the acquired message, filtering processing for a signal to be processed of the communications system of the first standard, wherein the performing comprises:
using a band-stop filter with a first bandwidth to perform filtering processing, when the indication of signal strength indicates that the signal strength is greater than a first threshold, for the signal to be processed of the communications system of the first standard; orusing a low-pass filter with a second bandwidth to perform filtering processing, when the indication of signal strength indicates that the signal strength is less than or equal to the first threshold and greater than a second threshold, for the signal to be processed of the communications system of the first standard; orusing a low-pass filter with the first bandwidth to perform filtering processing, when the indication of signal strength indicates that the signal strength is less than or equal to the second threshold, for the signal to be processed of the communications system of the first standard; whereinthe first threshold and the second threshold are preset values, and the first threshold is greater than the second threshold.
