Description

[Detailed Description of the Invention] [Summary] This is a monitoring method in which, in an electronic switching system, when the number of calls exceeding a predetermined communication time does not satisfy a predetermined value within a monitoring time, information on the corresponding subscriber is obtained.

[Industrial application field]

The present invention relates to a subscriber communication monitoring system, and more specifically to a subscriber communication monitoring system in which subscriber monitoring is performed using the number of incoming and outgoing calls that exceed the minimum communication time within each monitoring period.

It is important for the communication (speech) path exchanged and formed in an electronic exchange system to be formed without any failure in order to perform the communication normally.

However, the reality of electronic exchange systems currently in operation is that failures occur in the communication path system formed by exchange due to various failure factors.

Therefore, it becomes necessary to be equipped with technical means to monitor the occurrence of such failures.

[Conventional technology]

In the past, technical means for solving the above-mentioned technical problems have been developed and put into practical use. It is a processing means that periodically monitors subscribers who have been on the phone for a long time or are locked out (LOCK OUT) in an electronic switching system, and is also an automatic subscriber test means and an automatic subscriber circuit test means using commands using a test circuit.

[Problem that the invention seeks to solve]

According to the above-mentioned means, it is possible to detect most of the faulty subscribers that occur with each means individually, but it is not possible to detect all the faults that occur with each individual means, and it is difficult to detect special terminal faults etc. There are some problems where it is not possible.

The present invention has been made in view of the above-mentioned problems.It is an object of the present invention to make it possible to specify the minimum communication time of a call time, to enable special faults and detection targets to be determined according to purpose, and to easily and quickly detect faults. is its purpose.

[Means for solving problems]

The present invention will be explained using the principle block diagram shown in FIG.

In an electronic switching system, an exchange processing control unit (for example, a common control unit) is provided with a lower limit value for communication time used for call communication and a lower limit for the number of calls for each type of subscriber line accommodated in the electronic switching system. A registration means 9i for registering values is provided. Further, a counting means 11i for counting the number of calls whose communication time exceeds the lower limit of the communication time is provided corresponding to the subscriber line. and,
A determining unit 8 compares the number of calls counted by the counting means 11i within a predetermined monitoring time with the lower limit value of the number of calls, and outputs the subscriber information if the number of calls does not exceed the lower limit value. This is what I did.

Furthermore, the determining section is activated periodically so that the monitoring time is carried out at regular intervals, and by constantly monitoring, it is possible to detect failures, etc.

[Effect]

With the above configuration, when subscribers are divided into types such as general subscriber telephones, public telephones, PBX (private branch exchange)-accommodating subscriber telephones, etc., the talk time of calls made for each subscriber type, Since the number of such calls (or the number of incoming calls) that will occur within a predetermined period of time can be predicted, it is possible to detect subscribers (or lines) that are making and/or receiving calls that do not meet the conditions. Processing such as failure detection and countermeasures can be easily performed based on the subscriber information thus detected.

Furthermore, by changing and monitoring the lower limit value, it is possible to know the usage frequency of the subscriber, which can also be used to review the installation conditions of telephones, etc.

〔Example〕

FIG. 2 shows an electronic exchange system that is the object of the present invention. In this figure, 1 is a common control device (CC) of an electronic exchange, and 2 is a main memory that is connected to the common control device 1 and stores various information. 3 is a network controlled by the common control device 1 to form an exchange path (communication path) between a calling subscriber and a called subscriber. 4 is a line circuit, and 5 is a trunk. As shown in FIG. 3, the common control device 1 receives a monitored subscriber format (i in FIG. 3) in response to a command input from a typewriter provided on the common control device console (not shown). Registration or cancellation, lower limit of call time (see Figure 3)
t ₁ to _{t 3} ), a command processing means 6 for setting and changing the lower limit of the number of calls (n ₂ to _{n 2} in FIG. 3), and changing the monitoring cycle (T in FIG. 3); Means (see Figure 4) 7 and periodic processing means (see Figure 5)
8 is provided. The main memory 2 stores subscriber categories to be monitored (for example, general subscribers, public,
A call time/call count lower limit table 9 that registers the call time lower limit value and call number lower limit value for each PBX), a cycle counter table 10 that registers monitoring time and has a cycle counter (TCNT), and A call counter table 11 having a corresponding call counter (CNCNT) is provided to constitute the main part of the present invention.

The operation of the present invention under the above configuration will be explained below.

When the calling subscriber is connected to the called subscriber via the electronic exchange and the call is terminated, the common control unit (CC) 1 of the electronic exchange initiates call termination processing as shown in FIG. Therein, the call time is calculated (S1 in Figure 4), and the call time is compared with the lower limit of call time for that subscriber (S2 in Figure 4), and the call time exceeds the lower limit of call time. If so, the call counter (CNCNT) corresponding to the subscriber in the call counter table is incremented by 1 (S3 in FIG. 3).

In parallel with the call processing described above, the periodic activation control section 20 of the common control device 1 of the electronic exchange is operated as shown in FIG. (S10 in Figure 5), and when the counted value reaches the monitoring time T (S11 in Figure 4), the number of incoming and outgoing calls for that call counter (CNCNT) is added to each call counter. The number of calls is compared with the lower limit of the number of calls corresponding to the user (S12 in FIG. 5). Call counter (CNCNT)
When the number of incoming and outgoing calls is greater than the lower limit of the number of calls,
The cycle counter (TCNT) and call number counter (CNCNT) are cleared to 0 (S13 in FIG. 5).

On the other hand, if it is smaller, the subscriber's phone number (communication monitoring information) is output (S14 in FIG. 5) and the process in step S13 in FIG. , the periodic processing is repeated.

In this way, by performing subscriber-specific monitoring processing, it is possible to perform more detailed failure detection when handling subscriber call failures. In other words, even though general public telephones are installed on the premise that there will be more than a required number of calls per day, an abnormality may occur if usage does not meet certain conditions. It is thought that there are many people, and it will be effective in detecting them. Further, by arbitrarily setting the monitoring time, the lower limit value of call time, and the lower limit value of the number of calls, the fineness of failure detection is enhanced and various types of failures can be dealt with.

Although the above embodiments have been described with respect to telephone calls, the present invention can also be applied to other types of communication.

[Effects of the Invention] As described above, according to the present invention, since each terminal type can be monitored and a communication time lower limit value and a call number lower limit value are set corresponding to the type, abnormality detection processing can be performed for each usage type. Furthermore, it is possible to easily detect special failures such as abnormal terminals that are forcibly disconnected immediately after responding. In addition, abnormality monitoring can be performed by dividing the investigation target according to purpose.
