[Industrial application field]

The present invention relates to a failure notification method for notifying users of a dedicated communication network of the occurrence of a failure when a dedicated communication network fails.

In recent years, the number of dedicated communication networks called intra-company networks has been increasing, but as the dependence on dedicated communication networks for daily business increases, network management has become even more important. More and more places are installing network management systems. Furthermore, some dedicated communication network management systems are equipped with a fault determination processing device that automatically determines and displays the location of a fault when a fault occurs.

However, conventionally, when a failure occurs in a dedicated communication network, the people who are automatically notified of failure information are limited to network administrators or maintenance personnel, and the users of the dedicated communication network are automatically notified of the failure. Generally, notifications are not sent over the phone, and notifications are sent by phone or other means when necessary.

Nowadays, as dedicated communication networks become more sophisticated and complex, and the dependence on dedicated communication networks increases, there is a need to notify not only maintenance and operators but also users of failures as soon as possible. .

[Conventional technology]

FIG. 3 is a diagram showing the configuration of a conventional system.

In the figure, 3l is a dedicated communication network, 32 is a dedicated communication network management system, and 33 is a dedicated communication! This is a failure determination processing device that automatically determines the location of the failure and displays the information when a failure occurs in the il31.

Dedicated communication networks include those in which networks such as telephone networks and packet communication networks are set up individually, and those in which they are combined.
In addition, failure management is not only carried out on a rope-by-rope basis, but also on PBX
This is generally carried out in network units such as switching equipment, packet switching equipment, high-speed digital multiplex transmission equipment (MUX), and facsimile equipment (FAX).

It is now assumed that a failure has occurred in a part of the dedicated communication 131 and it has become unusable. For example, a fault may occur in a high-speed digital multiplex transmission equipment, making communication through the equipment impossible, but the PBX exchange itself that accommodates the line that goes through the equipment is not affected. Assume a case. The affected device 31a in FIG. 3 indicates the device that has caused the problem, and the non-affected device 3lb indicates the device that can be used without causing the problem.

The affected device 31a sends fault information to the fault determination processing device 33 when a fault occurs. The failure determination processing device 33 determines and displays the failure location by means not shown. The administrator of the dedicated communication line management system 32 takes necessary measures based on the determination result of the failure determination processing device 33, but if it is determined that it is necessary to notify the users of the dedicated communication 131 of the occurrence of a failure. Notification is done manually. For example, among the users of the dedicated communication y431 who use the telephone 34, for the user who has the telephone 36a housed in the non-affected device 3lb, the route via the non-affected device of the dedicated communication network is used. For the user accommodated in the affected device 31a, the public network 35 is connected to the telephone 36b, which is an accommodation terminal of the public line 35 installed adjacent to or in the vicinity of the user.
to notify you of the occurrence of a failure via a phone call.

Although only two terminals are listed in Figure 3 as the terminals that issue fault notifications, in reality, the terminals that issue fault notifications are determined based on the importance, frequency of use, etc. among the users of dedicated communication y431. An appropriate number is selected in advance, and the notification range may be changed depending on the scale of the failure. In addition, dedicated communication m
Even if some of the unaffected devices 3lb are available, all of them may be notified via the public communication network 35.

However, in any case, in the conventional method 2, the notification of a failure to the user is performed manually, so it takes time from the occurrence of the failure to the notification, which often causes confusion for the user.

[Problems to be Solved by the Invention] As described above, in the conventional system, users are notified of failures manually using telephones, etc., so it takes time from the occurrence of the failure to the notification, and users are required to use dedicated communications. For a while, it was unclear why the network was unavailable, which often caused confusion.

An object of the present invention is to automatically notify terminals of users of a dedicated communication network of the occurrence of the fault when a dedicated communication network fails.

[Means to solve the problem]

It is a terminal that accommodates public communication networks.

[For production]

In FIG. 1, it is assumed that a failure occurs in a part of the dedicated communication 11 and it becomes unusable. Affected device 1a in Figure 3
indicates the device that has caused this failure, and non-affected device 1b indicates a device that can be used without causing any failure. Affected device 1a
sends fault information to the fault determination processing device 3 when a fault occurs. The failure determination processing device 3 determines and displays the failure location by means not shown, and sends information regarding the failure location to the notification destination determining means 5.

On the other hand, the notification destination information storage means 4 stores in advance information on terminals to be notified when a failure occurs in the dedicated communication line 1. The information includes, for example, terminal identification information (telephone number, etc.), and information on the dedicated communication network 1 that makes it impossible for the terminal to communicate.
information on the location of the fault, the type of communication line used for fault notification (whether it is a dedicated communication network line or a public communication network line),
It consists of information such as communication media (voice, fax, etc.).

The notification destination determining means 5, which has received the information about the failure location from the failure determination processing device 3 as described above, receives the above-mentioned terminal information regarding the notification destination from the notification destination information storage stage 4, and selects the terminal 9a to notify the failure. , 9b and the terminal to be used, respectively, and output them to the automatic fault notification means 7. For example, the failure determination processing device 3
Based on the failure location information and the terminal information from the notification information storage means 4, the terminal 9a can be connected via the dedicated communication network when a failure occurs within the range of the affected device 1a, and the notification medium is It was decided that the terminal 9b would be connected via a public communication network if a failure occurs within the range of the affected device 1a, and the notification medium would be facsimile (FAX) communication. shall be

Here, the communication device 6a is a device that notifies by voice, for example, a communication device capable of transmitting a plurality of fault information by voice, and the communication device 6b is a device that sends a plurality of facsimile/text messages to a FAX receiving device as a fault notification. Assume that the communication device has the following.

The automatic failure notification stage 7 receives the identification information of the terminals 9a and 9b to be notified of failure from the notification destination determination means 5, and the communication line and communication medium used for each of the terminals.
A is connected to a line connected to the unaffected device 1a of the dedicated communication network 1, and connected to the terminal 9a by automatic calling. The terminal 9a
When the terminal 9a responds, the communication device 6a transmits the above-mentioned talkie voice to notify the terminal 9a of the occurrence of a failure. At the same time or subsequently, the automatic fault notification 7 connects the communication device 6b to a line accommodated in the public communication network 8, and automatically connects it to the terminal 9b. As mentioned above, the terminal 9b
Since this is a terminal having a FAX receiving function, when the communication device 6b responds, it sends one of the plurality of facsimile texts described above, and causes the terminal 9b to record the occurrence of the failure. When the automatic failure notification 7 completes a predetermined communication, it disconnects the communication line and restores the communication devices 6a and 6b.

Although only two terminals are shown in FIG. 1 as the terminals to be notified of a failure, notifications are made in the same manner even if there are many terminals to be notified.

As described above, according to the present invention, when a fault occurs in a dedicated communication network, the user of the dedicated communication network is automatically notified of the fault.
