Is a line alarm receiving unit that receives a communication line alarm message output from the communication line monitoring device 2. Reference numeral 12 denotes an alarm distribution destination determination unit that determines a destination to distribute the alarm information included in the communication line alarm message based on the content of the communication line alarm message received by the line alarm reception unit 11. Symbol 13 is
This is a distribution destination table that the alarm distribution destination determination unit 12 refers to when determining a distribution destination, and in this table, the identification number of the distribution destination alarm receiving terminal 4 is defined. Symbol 14 is
This is a table definition unit that defines distribution destination information for the distribution destination table 13. Reference numeral 15 denotes a distribution unit that distributes alarm information to the distribution destination determined by the alarm distribution destination determination unit.

Next, an operation of notifying an alarm of the communication line to the alarm receiving terminal 4 will be described with reference to FIGS. First, the communication line monitoring device 2 constantly monitors the status of the communication line, and sends out a communication line alarm message when an abnormality or the like is detected. FIG. 3 shows the format of the communication line alarm message. As shown in FIG. 3, the communication line alarm message includes a "type 1 communication company code" for identifying the type 1 communication carrier owning the abnormal line, and a customer using the line. "Customer code", "Line code" to identify the line
And "alarm information" indicating the content of the alarm.

Next, the line alarm receiving section 11 receives the communication line alarm message transmitted from the communication line monitoring device 2,
The communication line alarm message is held in the line alarm receiving unit 11 and the message is output to the alarm destination determining unit 12.

Next, the alarm distribution destination determining unit 12 receives the communication line alarm message output from the line alarm receiving unit 11 and includes a “first type communication carrier code” included in the message.
"Customer code" and "line code" are extracted.

Subsequently, the alarm destination determining unit 12 refers to the destination table 13 based on the extracted “first type communication carrier code”, “customer code” and “line code”, and Search for and extract candidates.

FIG. 3 shows a table structure of the distribution destination table 13. As shown in FIG. 3, the distribution destination table 13 includes “line number”, “first type carrier code”, “customer code”, “line code”, “distribution destination ID”, and “non-distribution destination ID”. It has six fields. "Destination I
“D” is an identification number for specifying the alarm receiving terminal 4 that distributes the alarm. When this “delivery destination ID” is “00000”
000 "means that no alarm is delivered unconditionally, and" **** "means that there is no corresponding delivery destination. The “non-distribution destination ID” means that the alarm is not distributed only to the alarm receiving terminal 4 having this identification number. This non-delivery destination I
When "D" is "****", it means that the alarm receiving terminal 4 that does not distribute is not specified.

Here, the distribution destination table will be described with reference to FIG. In each field of the distribution destination table 13, a blank field indicates that the code of the field is not specified. For example, "line number"
However, for "1 to 4", the "customer code" and the "line code" are blank, but these are the "type 1 carrier code", "customer code",
"Customer code" and "Line code" of "Line code"
Means to ignore. Therefore, if the “Type 1 carrier code” is “0077”,
Regardless of the value of “customer code” and “line code”, “delivery destination ID” is “AAA” and “non-delivery destination ID” is “****”.

Similarly, if only the "customer code" is defined, such as "line number" of "5-6", what kind of "type 1 carrier code" and "line code" are Even if it is a value, it means that it is distributed to the alarm receiving terminal 4 specified in the field of “distribution destination ID”.

When the "line number" is "8 to 10", only the "line code" is defined, and the "type 1 communication carrier code" and the "customer code" Also means to deliver to the delivery destination defined here. However, in this example, the “delivery destination ID” is “000”.
00000 ", alarm information is not unconditionally distributed. This can be applied to prevent an alarm from being notified many times when a specific line is under construction.

The alarm information in which the "line number" is "15" and the "customer code" is "555555555" is "US
"ER_E" is defined to be delivered to the alarm receiving terminal 4. However, if the "line number" is "16-18",
"Line code" is "88811111", "88822"
Only when the information is the alarm information of the line of “222” or “88833333”, it is defined that the information is not distributed to the alarm receiving terminal 4 of “USER_E”.

As described above, by defining the contents of the distribution destination table 13 as necessary, it becomes possible to select and distribute the alarm information to be distributed.

The distribution destination table 13 updates distribution destination information via the table definition unit 14.

Next, the alarm distribution destination determining unit 12 outputs to the distribution unit 15 the ID of the previously determined destination of the alarm receiving terminal 4 and the alarm information extracted from the communication line alarm message.

In response to this, the distribution unit 15 receives the ID of the alarm receiving terminal 4 and the alarm information output from the alarm destination determining unit 12, and distributes the alarm information to the alarm receiving terminal 4 having this ID. I do. The distributed alarm information reaches the alarm receiving terminal 4 via the Internet 3.

Next, a procedure of information transfer when the line alarm notification device 1 distributes alarm information to the alarm receiving terminal 4 will be described. FIG. 4 is a sequence diagram showing an information transfer sequence between the line alarm notification device 1 and the alarm receiving terminal 4. First, the alarm receiving terminal 4 transmits a connection request to the line alarm notification device 1 ((a) in FIG. 4).

In response to this, the line alarm notification device 1 authenticates the alarm receiving terminal 4 to which the connection request has been made, and returns a connection response to the alarm receiving terminal 4 (FIG. 4B).

Next, when the communication with the line alarm notification device 1 is established, the alarm receiving terminal 4 waits for alarm information to be transmitted from the line alarm notification device 1.

On the other hand, the line alarm notification device 1 waits for a communication line alarm message to be transmitted from the communication line monitoring device 2.
Then, when the communication line alarm message is transmitted, the line alarm is distributed by the above-described operation ((c) in FIG. 4).

In response, the alarm receiving terminal 4 receives the line alarm information and displays it on a display device (not shown).

Subsequently, the line alarm notification device 1 distributes a dummy line alarm after a lapse of a certain time (T2 in FIG. 4) from the distribution of the line alarm (FIG. 4 (d)). In addition, the line alarm notification device 1 distributes a dummy line alarm so that the period of no transmission to the alarm receiving terminal 4 does not become longer than the time T2. Therefore, when the communication line alarm message from the communication line monitoring device 2 is not transmitted, a period from when the connection response is transmitted (FIG. 4B) to when the connection response is disconnected (FIG. 4F). A dummy line alarm is always transmitted at intervals of time T2.
However, if the communication line alarm message is transmitted from the communication line monitoring device 2 during that time, a dummy line alarm is sent from the line alarm notification device 1 to the alarm receiving terminal 1 after a time T2 from the time when the communication line alarm message is received. 4 is transmitted. This time T2 is set to a time sufficiently shorter than the minimum value of the timeout time due to the continuation of the no-data state set in the proxy server 6 on the Internet connection path.

As a result, it is possible to avoid a timeout due to the continuation of the no-data state set in the proxy server 6 on the Internet connection path.

Next, when a line alarm is distributed from the line alarm notification device 1 (FIG. 4E), alarm information is displayed on the alarm receiving terminal 4 by the same operation as described above.

Next, the line alarm notification device 1 receives a connection request from the alarm receiving terminal 4 for a certain period of time (see FIG. 4).
After the elapse of T1), the communication with the alarm receiving terminal 4 is disconnected.
This time T1 is set to a time sufficiently shorter than the minimum value of the connection timeout time set in the proxy server 6 on the Internet connection path. As a result, a connection timeout set in the proxy server 6 on the Internet connection path can be avoided.

Next, when the communication with the line alarm notifying device 1 is disconnected, the alarm receiving terminal 4 transmits a connection request again to the line alarm notifying device 1 to execute the above-described procedure (FIG. 4).
(A) to (f)) are repeated.

By using the information transfer sequence shown in FIG. 4, it is possible to notify the alarm receiving terminal 4 of a line alarm in real time while complying with the Internet Protocol (HTTP).

Further, a program for realizing each function shown in FIG. 2 is recorded on a computer-readable recording medium, and the program recorded on this recording medium is read by a computer system and executed, whereby alarm information is obtained. May be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a portable medium such as a floppy disk, a magneto-optical disk, a ROM, a CD-ROM, and a storage device such as a hard disk built in a computer system.

Further, a "computer-readable recording medium" is a program that is dynamically transmitted for a short time, such as a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line. And those holding programs for a certain period of time, such as a volatile memory in a computer system serving as a server or a client in that case. Further, the above-mentioned program may be for realizing a part of the above-mentioned functions, or may be for realizing the above-mentioned functions in combination with a program already recorded in a computer system.

[0045]

As described above, according to the present invention, the following effects can be obtained. Many systems using the Internet perform processing on the server side in response to a request from the terminal and return the result to the terminal. According to the present invention, apparently, alarm information is received from the line alarm notification device by an alarm. The terminal can be notified in real time. Therefore, there is an effect that a customer who needs to receive alarm information can receive an alarm of a communication line using a general-purpose computer system.

According to the present invention, the distribution of the alarm information is determined with reference to the distribution destination table.
With the merger / separation of telecommunications companies and the entry of new telecommunications carriers, it is possible to easily change the distribution destination simply by updating the distribution destination table, even if a new line is installed or changed. The effect is obtained.
