Problems solved by technology

[0003] However, there are still some communication equipment faults that cannot be characterized by state indicators. They are expressed in the form of the occurrence or disappearance of specific discrete events, such as user connection failure faults during communication. When a user connection failure event occurs, the communication equipment is considered to be in a faulty state and is alerted, and when the connection is restored, the communication device is considered to be in a non-faulty state and the alarm is canceled
For the above-mentioned discrete events that occur more frequently in a period of time, if each time the event occurs, it is regarded as a discrete-event fault (hereinafter referred to as a frequent discrete-event fault) and the device is placed in an alarm state, And every time the event disappears and the device is placed in the no-alarm state, it may cause the communication device to switch between the two states frequently, affecting the stable operation of the device and reducing the operating efficiency of the system

Example Embodiment

[0019] Under normal circumstances, when a discrete event related to a failure occurs, it is considered that the communication device has failed, but as mentioned above, this will introduce the influence of accidental factors, resulting in frequent switching of the communication device failure state between the alarm and the cancellation of the alarm . For this reason, in the method of the present invention, the communication system uses the frequency of occurrence of such discrete events (that is, the number of occurrences of discrete events in a unit time interval) as a measure of whether the device is in a fault state, and compares this measure with a preset The threshold value is compared and the corresponding state transition is completed according to the judgment result.

[0020] In order to measure the frequency of occurrence of discrete events related to faults, the communication system selects a certain length of time interval T and uses this time interval T as a period to me

Abstract

This invention provides an alarm method for frequently happened discrete event faults in communication system. The said system takes the present time interval(T) as the period to execute the following steps to determine the state of a communication equipment related to the discrete event (1) to calculate times of discrete events happened in the present period, (2) comparing the said times with the present threshold value, (3) if the said times are smaller or equal to it, then the said device is set at alarmless state in the next period, or, it is set at the alarm state.
