Abstract

PURPOSE:To monitor special troubles for every purpose and to detect troubles quickly by obtaining subscriber information where the number of calls counted within a prescribed monitor time by a counting means does not reach a lower limit value to designate a lower limit communication time of the service time. CONSTITUTION:In an electronic switching system, a switching processing control part (for example, a common control part) is provided with means 9i which set a lower limit value (t) of the service time and a lower limit value (n) of the number of calls correspondingly to subscriber's lines (i)-i+1. Call number counting means 11i which update counted values when the service time exceeds a certain lower limit value are provided correspondingly to subscriber's lines. The counted value which each means 11i counts within the monitor time is compared with the lower limit value of the number of calls by a discriminating part 8, and corresponding subscriber information is outputted if the number of calls does not exceed the lower limit value. The discriminating part 8 is started periodically so that this monitoring is performed at a certain period, and steady monitoring is performed to detect troubles or the like.

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.

communications exchanged and formed in an electronic exchange system (
It is important from the viewpoint of normal communication that the communication path be formed without any obstacles occurring.

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 long call or lockout (LOCK) in an electronic switching system.
0UT) processing means for periodically monitoring subscribers in the state;
It is also an automatic subscriber line test means and an automatic subscriber circuit test means based on 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 by each means individually, but it is not possible to detect all the faults that occur with each means, and special terminal faults etc. cannot be detected by each means. There is also the problem that it cannot be detected.

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, a means 9i for setting a lower limit value t of call time and a lower limit value n of the number of calls for each subscriber line (i % i + n) in an exchange processing control unit (for example, a common control unit).
This is provided. Further, a call number counting means 11i is provided corresponding to the subscriber line to update the counted value when the call time exceeds a certain lower limit. Then, the determination unit (8) compares the count value counted within the monitoring time by the call count counting means with the lower limit value of the number of calls, and if the number of calls does not exceed the lower limit value, the subscriber information is output. This is what I did.

Further, the determining section is activated periodically so that the monitoring time is performed at a constant period, and by constantly monitoring, it is possible to detect a failure.

[Effect]

With the above configuration, the subscriber can, for example, use a general subscriber charger,
When subscriber telephones are divided into public telephones, PBXs (private branch exchanges), etc., the call duration and number of calls occurring (or number of incoming calls) within a predetermined time are predicted for each subscriber type. It is possible to detect subscribers (or lines) that do not meet the conditions despite the Based on this detected subscriber information, processing such as failure detection and countermeasures can be easily performed.

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 Φ installation conditions of telephones, etc.

〔Example〕

FIG. 2 shows an electronic exchange system that is the object of the present invention.

In this figure, ■ is the common control unit CCC of the electronic exchange
'), 2 is a main memory connected to the common control device 1 and storing various information. A network 3 is controlled by the common control device 1 and forms an exchange path (communication path) between a calling subscriber and a called subscriber. 4 is a line circuit, and 5 is a trunk. And, as shown in Figure 3,
The common control device 1 registers or cancels the type of subscriber to be monitored (i in FIG. command processing means 6 for setting and changing the call number lower limit value (n1 to ng in Fig. 3), and changing the monitoring cycle (T in Fig. 3); means (see FIG. 4) 7, and periodic processing means (
(see FIG. 5) 8 are provided. The main memory 2 stores monitored subscriber categories (for example, general subscribers, public).

A call time/call count lower limit value table 9 that registers the call time lower limit value and call number lower limit value for each PBX), a cycle counter table IQ that registers monitoring time and is provided with a cycle counter (TCNT), and Corresponding call counter (CNCN)
A call counter table 11 having a call counter table T) is provided and constitutes 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 electronic exchange's common control unit (
At CC) 1, the call termination process as shown in Figure 4 is started, during which the call time is calculated (Figure 4, 8
1), and the call time is compared with the call time lower limit value corresponding to that subscriber (Fig. 4, 82), and if the call time exceeds the call time lower limit value, the call time corresponding to the subscriber in the call counter table is compared. The call counter (CNCNT) is incremented by 1 (FIG. 33).

In parallel with the call processing as described above, the periodic activation control section 20 of the common control device 1 of the electronic exchange is operated as shown in FIG.
CNT) is incremented by 1 at every fixed period (Fig. 5, 81).
0), when the counted value reaches the monitoring time T (Fig. 4, 3
11) For each call counter, its call counter (CNCN
The number of outgoing and incoming calls of T) is compared with the lower limit of the number of calls corresponding to the subscriber (812 in FIG. 5). When the number of incoming and outgoing calls in the call counter (CNCNT) is greater than the lower limit of the number of calls, the cycle counter (TCNT) and the number of calls counter (CNCNT) are cleared to O (813 in FIG. 5).

On the other hand, if it is smaller, the telephone number (communication monitoring information) of the subscriber is output (814 in FIG. 5) and step S1 in FIG.
As in the case where no match is obtained in step Sll after performing the process in step 3, the periodic process 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 of call time, and the lower limit of the number of calls, the fineness of failure detection is enhanced, and it is possible to cope with various types of failures.

In addition, in the above embodiment, a telephone call was described, but
The present invention can also be applied to other types of communication.

〔Effect of the invention〕

As described above, according to the present invention, since each terminal type can be monitored and a lower limit value for communication time and a lower limit value for the number of calls are set corresponding to each type, abnormality detection processing can be performed for each usage type, and further, It is also 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.
