Abstract

PROBLEM TO BE SOLVED: To easily confirm the state of holding a receiver and to enable speaking even without executing a call originating operation again when a callee performs on-hook while a howler tone is sent out. SOLUTION: A test call, which is to be originated when a caller meets a callee busy for a long time, is identified (S103), at the time of test call, whether the callee is busy or not is discriminated (S104), when the callee is not busy, a ring back tone is sent out to the caller and the howler tone is sent out to the callee (S105 and S106). At the same time, a timer is started. When the callee performs on-hook before time out, a calling signal is sent out to the callee in place of the howler tone. When it is not the test call (S103), the cellee is busy (S104) and the timer gets time out (S107), a busy tone is sent out to the caller.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic test system for long-time busy subscribers, and in particular, a test for allowing a calling subscriber to easily confirm whether a called telephone terminal is busy or unhooked. Regarding the scheme.

[0002]

2. Description of the Related Art Busy conditions encountered when a calling subscriber dials a desired called subscriber's telephone number include the case of the called subscriber's long telephone call, the disconnection of the handset due to vibration, etc. There is a case where the receiver is in a so-called detached state due to forgetting to return the receiver at the end or half-hanging the receiver.

When a calling subscriber encounters during a call, he or she usually cannot know the cause of the call, and therefore repeats the calling operation many times, especially when the receiver is out of the handset. Even if you repeat, you will not be able to talk. For this reason, the exchange usually sends a howling sound to notify the called subscriber that the handset is in the handset disconnection state when the handset detachment continues for a predetermined period of time or more, and a procedure for quickly recovering the handset disconnection is usually performed. Such a handset disconnection recovery method is proposed in, for example, Japanese Patent Laid-Open No. 60-260258 (transmission connection method in an automatic exchange).

The outgoing connection system in this automatic exchange is
When the called party is busy or the line is busy When the caller is notified by calling the caller that the called party is busy or the line is busy, and the handset disconnection state is identified Sends a howler sound to the called party and sends a toe sound to the caller indicating that the called telephone terminal is sending the howler sound because the called telephone terminal is off the receiver. By notifying the middle cause by voice, the service for the caller is improved and the work time is shortened due to the decrease of the failure report to the subscriber test stand.

[0005]

In the conventional outgoing call connection method in the automatic exchange, when the caller encounters the called party while the called party is busy, the switching machine identifies the busy factor and the busy factor is called. If the caller is busy or line-busy, the caller is notified by voice.If the busy factor is the handset disconnection state, a howling sound is sent to the callee and the caller is called. Since the caller is configured to notify by voice that the howler sound is being sent because the caller is in the off-hook state, the called party who recognizes that the caller is in the off-hook state returns the handset to the on-hook state. Even after the call is restored, the caller must hook the handset to open the line once, and then dial the subscriber number of the called party again to make a call again.

Therefore, although the service to the caller is improved by notifying the caller of the busy factor and informing the current state of the callee side, the caller must re-call, so the service It cannot be said that the sexuality has improved sufficiently.

Further, in order to notify the calling party of the busy factor, it is necessary to connect the talkie device each time.
The central control unit of the exchange is overloaded and the processing capacity is reduced. Further, an expensive talkie device is required, and the cost of the exchange becomes high.

An object of the present invention is that a calling party encountered during a call can easily confirm the unhooked state of the called party telephone terminal, and the called party telephone terminal goes on-hook while sending out a howler sound. In this case, it is to provide an automatic test method for long-time busy subscribers, which can improve serviceability and maintainability for callers by enabling a call without performing a recall operation. .

[0009]

The automatic test method for a long-busy subscriber according to the present invention is a busy-subscriber test method performed by a calling subscriber when encountering during a long talk. When the calling party encounters the called party for a long time, the calling party issues a test call to confirm whether the called party is in a call with another telephone terminal or is in the state of disconnecting the handset. It is characterized in that the busy tone sent back from the terminal recognizes that the call is in progress and that the ringing tone indicates that the handset is disconnected.

Further, the test call is characterized in that a special number indicating that it is a test for a long-busy subscriber is added to the subscriber number of the called party.

The automatic test method for a long-busy subscriber of the present invention is a busy-subscriber test method performed by a calling subscriber when encountering during a long talk; When a caller encounters the called party for a long time, the test call originating for a long-term busy subscriber test is received and it is discriminated whether or not it is a test call based on the presence or absence of a special code included in the test call. A call identifying means; a busy identifying means for identifying whether or not the called telephone terminal is in a call when the test call identifying means identifies the special number "present"; and the busy identifying means for "non-call" When "medium" is identified, a first ringing tone is sent to the calling party telephone terminal and a howling tone is sent to the called party telephone terminal; ringing tone / howling tone sending means; Timer means for timing out after a lapse of time; the test call identification means recognizes the special number "none" A busy tone sending means for sending a busy tone to the caller telephone terminal when the busy identifying means identifies "busy", and when the timer means times out; An on-hook detecting means for monitoring the on-hook state of the telephone terminal; and when the timer means has not timed out and the on-hook detecting means detects the on-hook state of the called telephone terminal, the ringing signal is used instead of the howler sound. And a calling signal sending means for sending to the called telephone terminal.

A second ringing tone generator 80-2 that generates a ringing tone, a howler sound generator 90 that generates a howler tone, a busy tone generator 100 that generates a busy tone, and a predetermined call control program. The main storage device 70 is stored in advance, and the central control device 60 executes a call control process based on a program stored in the main storage device.

First, the long-time busy test operation of the first invention will be described with reference to FIG. 1 together with FIG. Caller telephone terminal 10
-1 repeatedly makes a call to the called telephone terminal 10-2, and when the telephone terminal 10-2 is in a busy state for a long time, the subscriber of the telephone terminal 10-1 temporarily goes on hook and then the telephone terminal 1
In order to confirm whether 0-2 is in a call with another telephone terminal, for example, 10-n, or is in the state where the handset is disconnected, the subscriber number of the telephone terminal 10-2 is redialed after the predetermined special number.

The central control unit 60 of the electronic exchange 20 receives the selection signal via the subscriber circuit 31-1 (step S100 in FIG. 1), performs numerical analysis and determines whether or not the call is an incoming call (step S101). ). When the central control device 60 determines that it is an incoming call, it subsequently determines whether or not the telephone terminal 10-2 is off hook (step S10).
2).

If the determination result is the on-hook state, the process proceeds to step S109, and a predetermined call signal generated by a call signal generator (not shown) is sent from the switch 40 to the subscriber circuit 3.
It is sent to the telephone terminal 10-2 via 1-2 (step S109). Here, when the telephone terminal 10-2 goes off-hook, the central control unit detects this and sets a predetermined call path of the switch 40, and the telephone terminals 10-1 and 10-
2 is connected and a call is established.

When the central processing unit 60 determines in step S102 that the telephone terminal 10-2 is off-hook, the received subscriber number is given a special number indicating that it is a long busy test. It is determined whether the call is a call (step S103). If the special number is not assigned, it is determined that the call is a normal incoming call, and the busy tone generating apparatus 10
A predetermined busy tone generated by 0 is sent to the telephone terminal 10-1 via the switch 40 to the subscriber circuit 31-1 (step S110).

If it is determined in step S103 that the test call has a special number, the telephone terminal 10-2
It is determined whether or not the busy factor is in a call with another telephone terminal by the presence or absence of a connection destination (step S104), and if there is a connection destination, a conversation with another telephone terminal (for example, 10-n) is in progress. Then, a predetermined busy tone generated by the busy tone generator 100 is sent to the telephone terminal 10-1 via the switch 40 to the subscriber circuit 31-1 (step S110).

In this way, the telephone terminal 10 is assigned a special number.
-2, if the busy tone is returned from the electronic exchange even when the telephone terminal 10-1 is called again, the subscriber of the telephone terminal 10-1 has the telephone terminal 10-.
It can be seen that 2 is in a call with another telephone terminal.

When it is determined in step S104 that there is no connection destination (during non-communication), the central control device 60 outputs a predetermined ringing tone generated by the ringing tone generating device 80 to the switch 40.
~ Sending to the telephone terminal 10-1 via the subscriber circuit 31-1 (step S105), and at the same time, the howler sound generator 1
A predetermined howler sound generated by 00 is sent to the telephone terminal 10-2 via the switch 40 to the subscriber circuit 31-2 (step S106), and a timer (not shown) is started.

The central controller 60 monitors the timer and, when a preset predetermined time has elapsed, determines that the telephone terminal 10-2 is in the receiver off state (step S107), and the busy tone generator 100 generates a predetermined signal. Switch the busy tone of 40
~ Sending to the telephone terminal 10-1 via the subscriber circuit 31-1 (step S110). The subscriber of the telephone terminal 10-1 knows that the telephone terminal 10-2 is in the handset disconnection state because the busy tone is returned from the electronic exchange instead of the ringing tone, and the calling subscriber makes a telephone call. The on-hook test of the terminal 10-1 ends the long-time busy test.

The central control unit 60 monitors the off-hook state of the telephone terminal 10-2 after transmitting the howler sound, and confirms the telephone terminal 10-2.
-2 subscriber hears the howl sound and notices that the handset is disconnected and on-hook is detected before a certain period of time (before the timer times out) (step S108), a predetermined ringing signal generated by the ringing signal generator is switched. 40 ~
The data is sent to the telephone terminal 10-2 via the subscriber circuit 31-2 (step S109). Here, if the subscriber of the telephone terminal 10-2 who hears the ringing by the calling signal responds off-hook and responds, the call state is established.

In this way, when the calling party dials the called party's subscriber number many times in the usual manner and the busy tone is returned each time, the called party's telephone terminal is To test whether you are in a call with a telephone terminal or when you are out of the handset, the caller adds a special special code in front of the called party's subscriber number and dials, and the busy tone is sent from the electronic exchange. Is returned, it is possible to recognize that the called party is in a call, and when the ringing tone is returned after the ringing tone is returned, it is possible to recognize that the handset is off the handset.

Further, when the called party goes on-hook while the ringing tone is returned, a ringing signal is sent to the telephone terminal of the called party instead of the howler sound, and the ringing by the ringing signal is heard. When the called party responds by going off-hook, the call remains in that state, and the caller does not need to make a redial operation.

Next, referring to FIG. 2 together with FIG. 4, the long-time busy test operation of the second invention will be described. Similar to the first invention,
When the calling telephone terminal 10-1 repeatedly calls the called telephone terminal 10-2 and the telephone terminal 10-2 is busy for a long time, the subscriber of the telephone terminal 10-1 once goes off-hook. The rear telephone terminal 10-2 is another telephone terminal such as 10-n.
In order to confirm whether the call is being made or the handset is disconnected, the subscriber number of the telephone terminal 10-2 is redialed after the predetermined special number.

The central control unit 60 of the electronic exchange 20 receives the selection signal via the subscriber circuit 31-1 (step S200 in FIG. 2), performs numerical analysis and determines whether or not it is an incoming call (step S201). ). When the central control device 60 determines that it is an incoming call, it subsequently determines whether or not the telephone terminal 10-2 is off hook (step S20).
2).

If the determination result is the on-hook state, the process proceeds to step S210, and a predetermined call signal generated by a call signal generator (not shown) is sent from the switch 40 to the subscriber circuit 3.
It is sent to the telephone terminal 10-2 via 1-2 (step S210). Here, when the telephone terminal 10-2 goes off-hook, the central control unit detects this and sets a predetermined call path of the switch 40, and the telephone terminals 10-1 and 10-
2 is connected and a call is established.

When the central processing unit 60 determines in step S202 that the telephone terminal 10-2 is off-hook, the received subscriber number is given a special number indicating a long-time busy test. It is determined whether the call is a call (step S203). If the special number is not assigned, it is determined that the call is a normal incoming call, and the busy tone generator 10
A predetermined busy tone generated by 0 is sent to the telephone terminal 10-1 via the switch 40 to the subscriber circuit 31-1 (step S211).

When it is identified in step S203 that the test call has a special number, the telephone terminal 10-2
It is determined whether or not the busy factor is in a call with another telephone terminal based on the presence or absence of a connection destination (step S204), and if there is a connection destination, a conversation with another telephone terminal (for example, 10-n) is in progress. Then, the predetermined busy tone generated by the busy tone generator 100 is sent to the telephone terminal 10-1 via the switch 40 to the subscriber circuit 31-1 (step S211).

In this way, the telephone terminal 10 is assigned a special number.
-2, if the busy tone is returned from the electronic exchange even when the telephone terminal 10-1 is called again, the subscriber of the telephone terminal 10-1 has the telephone terminal 10-.
It can be seen that 2 is in a call with another telephone terminal.

When it is determined in step S204 that there is no connection destination, the central controller 60 searches the ringing tone setting memory (not shown) and determines the ringing tone type information registered in advance (step S205). ). In the ringing tone setting memory, whether the ringing tone to be returned to the telephone terminal 10-1 when the connection destination is determined in step S204 is the first ringing tone or the second ringing tone is registered in advance. It is assumed that

When it is determined in step 205 that the first ringing tone is registered in the ringing tone setting memory, the first ringing tone generated by the first ringing tone generator 80-1 is switched to the switch 40. -If it is determined that the second ring back tone is registered by sending it to the telephone terminal 10-1 through the subscriber circuit 31-1 (step S206), the second ring back tone generator 80- The second ringing tone different from the first ringing tone generated by No. 2 is sent to the telephone terminal 10-1 via the switch 40 to the subscriber circuit 31-1 (step S21).
2).

The central control unit 60 sends the first or second ringing tone to the telephone terminal 10-1, and at the same time, outputs the predetermined howling tone generated by the howling tone generating unit 100 to the switch 4.
0 to the telephone terminal 10-2 via the subscriber circuit 31-2 (step S207), and a timer (not shown)
Start

The central controller 60 monitors the timer and when a preset fixed time elapses (step S20).
8), the telephone terminal 10-2 determines that the handset is disconnected, and sends a predetermined busy tone generated by the busy tone generating device 100 to the telephone terminal 10-1 via the switch 40 to the subscriber circuit 31-1. Yes (step S211). The subscriber of the telephone terminal 10-1 finds that the telephone terminal 10-2 is in the handset disconnection state because the busy tone is returned from the electronic exchange instead of the first ringing tone, and the calling party joins. Is a telephone terminal 10-1
The on-hook test ends the long busy test.

The central control unit 60 monitors the off-hook state of the telephone terminal 10-2 after sending out the howler sound, and confirms the telephone terminal 10-2.
-2 subscriber hears the howler sound and notices that the handset is disconnected, and detects that the receiver is off-hook before a certain period of time (before the timer times out) (step S209), the predetermined ringing signal generated by the ringing signal generator is switched. 40 ~
The data is sent to the telephone terminal 10-2 via the subscriber circuit 31-2 (step S210), and the processing of the long-time busy test program ends. Here, if the subscriber of the telephone terminal 10-2 who hears the ringing by the calling signal responds off-hook and responds, the call state is established.

In this way, when the calling party dials the called party's subscriber number many times in the usual manner and the busy tone is returned each time, the called party's telephone terminal is To test whether you are in a call with a telephone terminal or when you are out of handset, the calling party dials with a special special code in front of the called party's subscriber number, and the busy tone from the electronic exchange. If the call is sent back, it recognizes that the called party is in a call, and if the first ringing tone is returned and then the busy tone is returned, it is recognized that the handset is disconnected. You can

When the second ring back tone is returned, the ring back tone is the same as the ring back tone that is usually returned (when the handset is not disconnected) when the second ring back tone is returned.
Since it is a ringing tone different from the ringing tone of, it is possible to recognize that the howler tone is being sent out before listening to the busy tone returned instead of the second ringing tone after a certain time. , It is possible to recognize the handset disconnection state of the called telephone terminal more clearly and in a short time.

Further, if the called party goes on-hook while the ringing tone is returned, a ringing signal is sent to the telephone terminal of the called party instead of the howler sound, and the ringing by the ringing signal is heard. When the called party responds by going off-hook, the call remains in that state, and the caller does not need to make a redial operation.

Although both the first and second inventions have been described with respect to the automatic test method for the long-busy subscriber on the extension line, the automatic line test for the outside line via the station line trunks 50-1 to 50-m is performed. In this case, the effect of the present invention does not change.

[0042]

As described above, according to the first aspect of the present invention, when a caller encounters during a long talk of a called party, the cause of the long talk is talking to another telephone terminal. If a special number indicating a long busy test call is added before the called number of the called party in order to test whether the called party is in the status When a call is being made to another telephone terminal, the busy tone is returned as usual, and when the handset is off, a howling sound is sent to the called telephone terminal and a normal ringing tone is sent to the calling telephone terminal. Return the
Since it is configured to send the busy tone instead of the ring tone after a certain period of time, the caller can easily identify the unhooked state of the called terminal by listening to the busy tone after receiving the ring tone. The serviceability to the caller is improved.

When the called party goes on-hook while the howler sound is being sent to the called party telephone terminal, when the called signal is sent instead of the howling sound and the called party answers, the call state is maintained. , The caller does not need to perform redialing operation, and the serviceability to the caller is improved. Furthermore, since it is possible to deal only with software without adding hardware,
The manufacturing cost of the electronic exchange is unchanged. Furthermore, it is easy to adapt to the existing exchange system.

In the second invention, ringing tone type information is registered in advance in the ringing tone setting memory, and like the first invention, when a special number is added to the called party's subscriber number and dialing is performed, the electronic When the called party is not in a call, the exchange searches the ringing tone setting memory and returns the ringing tone to the calling telephone terminal.
Since the first ringing tone which is the same ringing tone as in the first invention and the second ringing tone having a different first ringing tone are selected and returned, the first ringing tone is stored in the ringing tone setting memory. By setting the ringing tone of No. 2, whether the caller is calling the called party's telephone terminal which is not in the handset disconnection state or whether the howler sound is being sent out in the handset disconnection state, a second call is made after a certain time. Before hearing the busy tone returned instead of the sound, it is possible to recognize that the Howrah sound is being sent to the called telephone terminal, so the called telephone terminal is in the off-hook state. This can be surely recognized in a short time.

Further, as in the first aspect of the invention, when the called party goes on-hook while the howling tone is being sent to the called party telephone terminal, when a calling signal is sent instead of the howling tone and the called party responds,
Since the call is maintained as it is, the caller does not need to perform redialing operation, and the serviceability to the caller is improved.
