Abstract

PURPOSE:To attain quick connection by implementing recall immediately when the number of times of recall up to that point of time is less than a specified number, implementing recall immediately when the number of times in much and a reference time elapses and stopping recall till the reference time elapses when the reference time does not elapse so as to prevent production of a useless wait time. CONSTITUTION:An ISDN side I/F 3 being an interface with an ISDN network, a personal computer side I/F 4 being an interface with a personal computer body, and a memory 5 (storage means) storing a program to manage the number of times of dialing are connected to a CPU 2. When an ISDN board 1 is started, the CPU 2 of the ISDN board 1 reads the program from the memory 5 and sets the number of dial times A being a variable to manage the number of times of dialing having already been made to zero. Then a dial request by the operator is awaited and when a dial request comes, prescribed dial management processing is implemented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an ISDN (Integrated Services Digital Network) installed in a personal computer, for example.
) It relates to a recalling management device which is provided in a terminal device such as a board for connecting a line to a network.

[0002]

2. Description of the Related Art For example, a connection from a personal computer which does not have a user / network interface (I interface in the case of ISDN network) compatible with a network such as ISDN network to a network is performed by an external expansion bus (expansion slot) of the personal computer. A communication board having the above interface is mounted, and this communication board is used.

In the above communication, when a large amount of communication is performed at one time, the processing capacity of the network reaches the limit and congestion occurs. Therefore, in order to prevent congestion, the ISDN network, which is one of the networks, is provided with a restriction criterion by JATE (Telecommunication Terminal Equipment Examination Association) to limit the number of re-calls to the ISDN network to 2 times within 3 minutes. Further, only communication boards that can meet the standard are approved.

However, with a communication board that manually recalls calls, the operator must manage the number of recalls.
Even with authorization, it is often impossible to manage the actual number of recalls. Therefore, a communication board that automatically calls again is manufactured. In such a communication board, in order to meet the above criteria, a forced waiting time of 1 minute is provided after the first call, and a re-call is automatically made once every waiting time. It is set.

FIG. 6 shows a flowchart of the recalling process at this time. That is, first, the operator manually makes a call (S50). If the other station does not respond (S51), it automatically waits for 1 minute (S52), and then the call is automatically re-established (S50). In this way, the waiting for 1 minute and the recalling are repeated.

[0006]

However, in the communication board configured to perform the above-mentioned automatic re-call, even if the connection is possible with the waiting time of less than 1 minute, the waiting time of 1 minute is always required. To be For this reason, there is a problem in that a wasteful waiting time occurs and a quick connection cannot be established.

The present invention has been made in view of the above problems, and an object thereof is to generate useless waiting time when a partner station responds with a re-call within the upper limit of the number of re-calls within a predetermined time. It is to provide a communication board that can prevent the above and enable a quick connection.

Another object of the present invention is to provide a communication board which can simplify the recalling operation.

[0009]

In order to solve the above problems, the recall management apparatus of the present invention is a terminal connected to a network provided with a standard for limiting the number of recalls within a standard time to n times. In the recalling management device that manages the recalling of the device, a recalling number managing means that manages the number of recalling calls,
When a calling request is issued, a calling means acquires a calling time each time a calling is made, and stores each calling time up to (n + 1) times before. n-
1) When the number of calls is less than (n-1) when the number of calls is less than (n-1), the current time is (n + 1) times before the reference time. It is determined whether or not has elapsed, and if the reference time has elapsed, a recall call is immediately performed, and if the reference time has not elapsed, the recall call is stopped until the reference time elapses. It is characterized by having and.

[0010]

With the above configuration, the recalling management apparatus of the present invention automatically determines whether or not the above criteria are satisfied even if a recalling is performed when the recalling request is manually issued by the operator. If it is not satisfied, the recalling call is stopped.

As a result, it becomes possible to manage so as to satisfy the above-mentioned criteria even by manual operation.

[0012] Further, until the number of re-calls already made reaches the limit value n times, when the re-call request is issued, the re-call is immediately made without any waiting time.

As a result, when the other station responds with a re-call within the upper limit number of times, it is possible to prevent the unnecessary waiting time from occurring, and it becomes possible to connect quickly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe one embodiment of the present invention with reference to FIGS.

As shown in FIG. 2, this I which is a communication board for connecting to an ISDN network which is one of the networks.
The SDN board 1 (recall management device) is provided with a CPU (Central Processing Unit) 2 that performs processing necessary for communication. The CPU 2 has an ISDN I / F 3 that is an interface with the ISDN network, and a personal computer body. PC side I / F 4 which is an interface with (not shown)
And a memory 5 (storage means) in which a program for managing the number of callings is stored. The personal computer body includes a monitor (not shown) having a display screen for displaying. The memory 5 has a variable Tbl described later.
[1], Tbl [2], and Tbl [3] are also stored. Then, the CPU 2 reads the above program from the memory 5 and performs a call management process. That is, in the present embodiment, the recalling number managing means and the recalling managing means are functional modules constituted by the program stored in the memory 5 and the CPU 2 executing the program.

The present embodiment describes an example in which the present recalling management apparatus is applied to the ISDN board 1. However, the present invention is not limited to this, and other devices connected to the network, such as a telephone or a facsimile, are used. It is also applicable to other terminal devices.

Next, the operation of the call management process will be described. When the operator issues a command to activate the ISDN board 1 in the personal computer main body, the command is transmitted to the ISDN board 1 via the personal computer side I / F 4 and the ISDN board 1 is activated. Then, the CPU 2 in the ISDN board 1 reads the program from the memory 5, and first sets the value of the number of times of calling A, which is a variable for managing the number of times of calling already made, to zero. And wait for the call request from the operator,
When a call request is made, the call management process shown below is started. Flowcharts of this call management process are shown in FIGS. 1 and 4.

First, the current time is acquired (S1). Next, the number A of calls is checked (S2).

Since the number of calls A is 0 at this time, the process goes to S3, and the obtained current time is written in Tbl [3]. Then, the number of calls A is increased by 1 (S4) (therefore, the number of calls A becomes 1). After that, a calling process is performed via the ISDN I / F 3 (S5).

When the connection with the partner station is established and the line is disconnected thereafter, the number A of calls is changed to zero.

When the connection with the partner station cannot be established, this I
If a request for re-calling is made again without terminating the SDN board 1 or resetting or turning off the power of the personal computer, the current time is acquired as above (S1).
After that, S2 to S
6 and write the acquired current time in Tbl [2]. Then, in S4, the number of times of calling A is increased by 1 to 2 (S4), and then a calling process is performed (S5).

If the re-call request is made again without the termination of the ISDN board 1 or the like, the above process is repeated. However, the number of calls A is now 2
Therefore, the process proceeds from S2 to S7, and the acquired current time is written in Tbl [1]. Then, in S4, the number of calling times A is increased by 1 to 3 and then the calling process is performed (S
5).

At this point, the call has already been made three times. FIG. 3 shows a time table showing the writing status of each calling time at this time. That is, the above Tbl
[1], Tbl [2], and Tbl [3] respectively indicate the calling time one time before, the calling time two times before, and the calling time three times before.

If the re-calling request is made again without the termination of the ISDN board 1 and the like because the connection with the partner station cannot be established this time, the above-mentioned processing is repeated again.
Do not call again immediately. This is because the JATE (Telecommunications Terminal Equipment Examination Association) has established a standard that sets the number of re-calls to the ISDN network to 2 times within 3 minutes.

In order to satisfy the above criteria, first, the current time is acquired in the same manner as described above (S1), and then S2 is obtained in accordance with the number A of calls.
To S8. Here, since the call has already been made three times, the following formula is evaluated to satisfy the above criteria. Current time-Tbl [3] <180 seconds (1) If the expression (1) is true, it is 3 from the call three times before to the present.
Minutes have not passed, in other words, if a call is made now, the call is retried three times within 3 minutes, which violates the JATE standard. Therefore, in this case, the recalling process is stopped (S9).

At this time, an error message is displayed on the display screen, indicating that the call cannot be recalled because the JATE standard is not satisfied, and how many minutes should be left before the call can be recalled.

If the expression (1) is false, it means that 3 minutes have passed from the call made three times before to the present, in other words, the call has been recalled only twice in the past 3 minutes. So, even if you make a call now, you will still meet the JATE standards. Therefore, in this case, the call is made. However, before that, it is necessary to perform the following work.

That is, the calling time two times before the current time point becomes the "calling time three times before the current time point" after one re-call from now on. On the other hand, if a call is requested again after making a call again from now, the number of calls A
According to (A = 3), the process proceeds to S8 and the above expression (1) is evaluated again. At this time, the "calling time three times before the current time" can be handled using Tbl [3]. There is a need to.

The time table rewriting process (S10) is a process for performing the above work, and its flowchart is shown in FIG.
Shown in. First, the value of Tbl [2], which indicates the calling time two times before from the present time, is changed to Tbl [3] which is the calling time three times before from the time point after one call is recalled. ]
(S21).

Next, similarly to the above, the value of Tbl [1] (calling time one time before before from the current time) is set to Tbl [2] (two times before from the time point after one re-call from now on). (Calling time of) (S22), and then write the current time to Tb
It is written in l [1] (calling time one time before, as viewed from the time point after one call is made again) (S23).

This time table rewriting process (S1
0) is completed, the process proceeds to call origination (S5) in the flowchart of FIG.

Again, it is not possible to connect to the other station, and
When the call is requested again, the above process is repeated.
However, if the above S8 check is performed again and a call can be made, the call reoccurrence process is performed while shifting each call origination time by one again at S10. In this way, the call management process is completed.

As described above, in the ISDN board 1 of this embodiment, when a manual re-call request is issued, the JATE "permits re-call up to twice in 3 minutes" criterion even if the current re-call is made. It is automatically judged whether or not is satisfied, and if not satisfied, the re-call is not made.

As a result, even if it is manually operated, the JATE
It can be managed to meet the criteria of.

In addition, until the number of calls already made reaches three times, if a request for re-call is issued, the call is re-issued immediately without any waiting time.

As a result, when the partner station responds by calling again within two times, quick connection becomes possible.

Further, in the above-mentioned call management process, the operator manually issues a call request, but it can be omitted and automated.

In this case, when the ISDN board 1 is started up, the value of the number of calls A, which is a variable for managing the number of calls already made, is set to zero. Then, it waits for a call request from the operator, and if there is a call request, the call management process described below is started. This call management process will be described with reference to the flowchart shown in FIG.

First, the current time is acquired (S31), and the number A of calls is checked (S32).

The writing of the current time, the increase of the number of calls A, and the calls shown in S33 to S35, respectively, are performed in the same manner as the manual re-call management process shown in the flowchart of FIG. If it is not possible to connect to the partner station in S36, rather than waiting for the operator's manual re-call request, a predetermined standby time (that is, one minute) shorter than a predetermined preset time (that is, one minute) is set. Eg 30
Wait for only seconds) (S37) and then return to S31.

Since this waiting time can be freely changed by the operator in advance for the ISDN board 1, it is possible to make a short-term re-call for the first and second re-calls. Has become.

When the number of calls A is 1 and 2, the current time is written (S38 and S39), the number of calls A is incremented by 1 (S34), and the call is made (S35), as in the flowchart of FIG. Then, when it is not possible to connect with the other party (S3
6) The same as above, after waiting for a predetermined time (S37), S
Return to 31.

When the number of outgoing calls A = 3, that is, when the number of outgoing calls actually made is three or more, whether or not the JATE standard is satisfied is determined in the same manner as the flowchart shown in FIG. 1 (S40). ). However, when the criteria are met, the timetable rewriting process (S42) and the calling (S
35) and waiting for the above-mentioned predetermined time (S37), if the standard is not satisfied, the call is stopped (S4).
1) and returns to S31. Then, the determination in S40 is repeated until the criterion is satisfied, and if the criterion is satisfied, the call is made as described above (S35).

As described above, the automated ISDN described above is used.
After the first call, the board 1 does not wait for a request for a manual call again, but repeats the call twice with a predetermined waiting time, and thereafter, it goes up from that point for three minutes. If the call has been made three times, the call recall process is stopped, and if not, the call is recalled again.

Therefore, the operator sets the waiting time in advance to be shorter than the conventional set time (that is, one minute), so that the operator does not manually request a recall call and the JATE standard is set. 2 quickly while meeting
Recalls are made twice.

As a result, even when it is automated, when the partner station responds with a re-call within two times, it is possible to prevent the useless waiting time from occurring and to make a quick connection.

The ISDN board 1 of this embodiment is IS
Although it is dedicated to the DN network, the above-mentioned recalling management processing is performed by ISDN.
The present invention can be applied not only to the network but also to any communication network such as the ISDN network in which the frequency of the recalling is limited.

[0048]

As described above, the recalling management device of the present invention manages the recalling of the terminal device connected to the network provided with a standard for limiting the number of recalling calls within the reference time to n times. In the recalling management device, a recalling number managing means for managing the number of times of recalling, and a storage means for acquiring a calling time for each calling and storing each calling time at least (n + 1) times before. When a request for re-calling is issued, if the number of re-calling up to that point is (n-1) or less, the re-calling is immediately performed, while the number of re-calling up to that point is (n-).
1) When it is more than the number of times, it is judged whether or not the current time has passed the reference time from the (n + 1) th previous call time, and when the reference time has passed, the call is reissued immediately. If the reference time has not elapsed, the recalling management means stops the recalling call until the reference time elapses.

Therefore, there is an effect that it is possible to manage so as to satisfy the above criteria even by manual operation.

Further, when the other station responds with a re-call within the upper limit number of times, it is possible to prevent an unnecessary waiting time from occurring and to achieve a quick connection.
