ABSTRACT:
A method of detecting a signal degrade of transmission data, a method of detecting a restoration from a signal degrade, and a signal restoration detecting device are provided. The method of detecting a signal degrade includes measuring a discarded data rate of traffic; and comparing said discarded data rate with a threshold value to detect the signal degrade. The method of detecting restoration from a signal degrade includes obtaining a first value by multiplying a threshold value and a multiplier, the threshold value used to detect a signal degrade; and comparing a discarded data rate of a control traffic after a signal degrade with the first value to detect a restoration from the signal degrade. The methods and devices disclosed herein are suitable for precisely determining a signal degrade in a communication system.
