As shown in fig. 1, the method for alarming channel degradation and network overload provided in this embodiment mainly includes: the method comprises an information acquisition step, an information analysis step and an alarm prompt step.
An information acquisition step of acquiring channel response estimation information and bandwidth information; in the information acquisition step, the channel response estimation value with high reliability can be counted through the channel response estimation of each signal point, so that the channel response estimation value is calculated. The bandwidth information may refer to reasonably allocating network traffic transmission to ensure normal transmission of real-time services in a limited bandwidth, so that the phenomenon of network congestion (i.e., network overload) due to too large traffic volume, which causes mosaic of video or discontinuity of audio, is avoided.
An information analysis step, which analyzes the channel response estimation information and the bandwidth information and judges whether channel deterioration and network overload phenomena exist or not; in the information analysis step, whether a channel deterioration phenomenon exists can be judged through the analysis of the channel response estimation information; and judging whether the network overload phenomenon exists or not by analyzing the bandwidth information. The network overload phenomenon may refer to a phenomenon that a transmission workload exceeds a normal transmission capacity of a network in a network transmission process.
And an alarm prompting step, namely performing alarm prompting when the information analysis step judges that the channel deterioration phenomenon and/or the network overload phenomenon exist. Channel deterioration phenomena may cause transmission signal attenuation, etc.; the network overload phenomenon can cause that signals cannot be transmitted or processed in time, and the like; the generation of the channel deterioration phenomenon or the network overload phenomenon directly affects the normal operation of the system.
