Abstract

The present invention relates to a system diagnosis apparatus and method for promptly diagnosing a subscriber line in which a call failure or a failure in a corresponding line exceeds a predetermined threshold value in a switching system, thereby allowing a system operator to take action. In case of a call failure, the reason for the failure of the call is received from the call processing software, and the number of call failures of each line is accumulated, and the cumulative value is periodically examined to quickly diagnose the subscriber line exceeding the threshold and notify the operator to take action. To improve the quality of service to subscribers.

Description

An apparatus and method for diagnosing a system

The present invention relates to a system diagnostic apparatus and method, and more particularly, to a system diagnostic apparatus and method for automatically verifying the presence or absence of a subscriber line in case of a call failure due to an abnormal call attempt or abnormal cause of a telephone subscriber.

In the conventional switching system, there are two methods for determining the normality of the subscriber line.

First, there is a method of requesting an operator to test the normality by designating a specific subscriber line desired and determining the normality as a result.

Second, there is a method of requesting the operator to test the normality of all subscriber lines mounted by specifying a specific time, and determining the normality as a result.

These methods are performed without a direct connection with call processing, and the operator designates a specific subscriber or requests all subscribers to be normal at a specific time, that is, at the minimum time (the time of the least call during the day).

This is inconvenient to delay the determination of the normal status until the request to the operator or when the abnormal subscriber occurs.

Accordingly, the present invention has been made in view of the above-described conventional situation, and a system diagnosis apparatus for prompting a system operator to take an action by quickly diagnosing a subscriber line having a call failure or a failure in a corresponding line above a predetermined threshold in a switching system. And to provide a method.

In order to achieve the above object, a system diagnostic apparatus according to a preferred embodiment of the present invention includes: call processing means for detecting a failure occurrence or a subscriber call failure during call processing;

Receiving a call failure history from the call processing means increases the number of call failures per subscriber line, and periodically checks the call failure times for each subscriber line accumulated when entering the automatic test mode, and has a call failure count exceeding a threshold. It is provided with a maintenance means for diagnosing the problem and informing the operator of the result.

In addition, the system diagnosis method according to an embodiment of the present invention, the process of detecting a call failure occurring in the call processing process,

Receive the detected call failure details to increase the number of call failures for each subscriber line, and periodically check the call failure times for each subscriber line accumulated when entering the automatic test mode, and then for the subscriber lines having the number of call failures above the threshold. After the diagnosis is made, the result is notified to the operator.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a system diagnostic apparatus according to an embodiment of the present invention, reference numeral 10 denotes a call processing unit for detecting a failure or a subscriber call failure during normal call processing, and reference numeral 20 denotes a call processing unit ( 10) Receives call failure history from subscribers, increases the number of failures per subscriber line (cumulative), and checks the number of call failures per subscriber periodically (particularly every minute) when entering the automatic test mode. After the test is performed on (to be diagnosed; the line / circuit), the maintenance unit is notified to the operator 30 of the result. The operator 30 may set the threshold and change the set threshold.

Here, the subscriber line refers to the overall concept of the physical components connected from the telephone terminal to the switching system, and the threshold refers to the limit of any number of call failures determined by the operator as valid.

Next, a system diagnosis method according to an embodiment of the present invention will be described based on the flowchart of FIG. 2.

The diagnostic operation according to the embodiment of the present invention operates when the following three cases occur.

That is, in case of call initiation from non-existent subscriber, in case of call initiation / call termination request signal in normal subscriber line, in case of call failure in normal call processing.

First, in the first case, when a call initiation is requested from a subscriber, the call processing unit 10 first searches a database that stores subscriber mounting information to check whether the subscriber is registered, and then performs the next call processing only when it is determined to be a normal subscriber. Will continue processing. However, if it is determined that the subscriber does not exist (step 21), the call processing unit 10 notifies the maintenance unit 20 of the call failure (24) to increase the number of call failures of the corresponding subscriber line.

In the second case, the allowance value of the call initiation / call termination signal received in the normal subscriber line is set as a threshold for a predetermined time, and when the call initiation / call termination signal is received above the threshold, the call processing unit 10 receives the corresponding subscriber. The maintenance unit 20 is notified of the abnormal signal reception due to the line failure (step 22) (step 24). Accordingly, the maintenance unit 20 immediately increases the number of call failures of the corresponding subscriber line, which stores the number of failures, in order to test unconditionally in the next automatic test mode, above the threshold.

In the third case, when a call failure occurs in the normal call processing step before the number translation (step 23), the call processing unit 10 notifies the maintenance unit 20 of the call failure (step 24). Accordingly, the maintenance unit 20 increases the number of call failures. In this case, it is assumed that a call failure is a case in which a connection of signaling equipment that can receive and process a number pressed by the subscriber is not normal, and the subscriber hangs up without pressing any number after requesting to start a call by lifting a telephone receiver.

For these cases, if the number of call failures for each subscriber line is stored / managed, and if the automatic test mode is entered (“Y” in step 25), the number of call failures for each subscriber line is queried every minute. 26) and compare with the threshold specified by the operator. As a result of the comparison, when there is a line having a call failure count per subscriber line equal to or greater than the threshold (“Y” in step 27), the maintenance unit 20 determines the subscriber line as a diagnosis target and performs circuit and line test on the subscriber line as the diagnosis target. (Step 28). Then, the maintenance unit 20 notifies the operator 30 of the result of the test (step 29), and as a result, the operator 30 sees the test result and takes action when the subscriber line is broken. (Step 30).

According to the present invention as described above, in the field of maintenance, call failure and failure occurs in connection with the call processing field, deviating from the passive concept such as the diagnosis of subscriber lines by a conventional operator and the diagnosis of all subscriber lines mounted at the latest time. By performing a quick diagnosis on these frequent subscribers and notifying the operator to take action, the system reliability and the quality of service to the subscriber can be improved.

On the other hand, the present invention is not limited only to the above-described embodiments, but may be modified and modified without departing from the scope of the present invention.
