The subscriber of the third telephone who heard the busy tone had to redial occasionally to call the first telephone, which was troublesome to operate.

On the other hand, a method has been proposed in which the third telephone is called back when the first telephone is released from the busy state. However, in this case, the billing and the priority order when there are a plurality of telephones to call back are disclosed. There wasn't.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention does not require redialing when the calling party is busy, and automatically calls when the calling party is released from busy. Connection is made and raises the issue of billing during this time.

[0005]

In order to solve the above-mentioned problems, the present invention sets the calling telephone (third telephone) to be in an off-hook state when the calling party (first and second telephones) is busy. When the call is continued, even when the other party's busy state is released, the means to enter the call state, the billing means, and the calling side telephone (third telephone) being on-hook while the other party is busy. Means is provided for returning the third telephone to bring it into a call state after the other party's busy state is released, and a billing means at that time.

[0006]

1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, 1a to 1x are calling telephones (hereinafter referred to as "telephones"), 2a to 2x are called telephones (hereinafter referred to as "telephones"), 3 is a switching device, and 4 is a telephone 2a to.
Detects if the 2x is busy or has ended,
A state detecting device 5 having a function of notifying the information to the control device 8 detects a call from the line 11, a call to the line 11, and an ID sent from the public communication network to detect the control device 8.
It is a signal detection device having a function of notifying to.

Reference numeral 6 denotes a call back confirmation signal sent from the telephones 1a to 1x, a waiting time signal, and the telephone 1a.
~ 1x is a calling side signal transmission / reception trunk having a function of detecting whether or not 1x continues to be in an off-hook state for waiting and notifying the control device 8 and a function of sending a ringing tone, and 7 to telephones 2a to 2x A destination signal transmission / reception trunk having a function of transmitting a call back start signal and receiving a confirmation signal from the telephone to notify the control device 8 and a function of sending a ringing tone; 8 is a control device including a microprocessor; It is a memory.

Next, the specific operation will be described with reference to the flow charts showing the operation procedure of FIGS. For example, if the calling operation of the telephone set 1a is detected via the signal detection device 5, step S1 becomes affirmative, and then the telephone set 1a
When the telephone number (for example, for the telephone 2a) is detected through the signal detection circuit 5 (step S2), if the telephone 2a is idle (on-hook) by the state detecting device 4, the telephone 2a receives the signal from the receiving side signal transmission / reception trunk 7. A ringing tone is transmitted (step S3).

Then, the response of the telephone 2a is detected by the state detecting device 4
When it is detected through (step S4), the state detection device 4
The control device 8 receives a signal from the telephone set 1 and the telephone set 1a and the telephone set 2a are connected to each other for a call via the communication path device 10 by the signal from the control device 8 (step S5).

Subsequently, the call start time is recorded in the area for the telephone 1a of the processing memory 92 for charging the telephone 1a (step S6).

Then, when the call ends and the end signal due to the on-hook of the telephone 1a is detected by the signal detection device 5, the step S7 becomes affirmative, and the call end time of the telephone is recorded in a predetermined area of the processing memory (step S7). S8), frequency calculation processing is performed to calculate the call charge, and the result is recorded in the area of the telephone 1a of the frequency meter 91 (step S).
9).

On the other hand, the control procedure shown in FIG. 2 and the control procedure shown in FIG. 3 can be operated in parallel. Therefore, when a call is made from, for example, the telephone set 1x and an incoming call is made to the telephone set 2a in the above-described telephone call state between the telephone set 1a and the telephone set 2a, it is identified via the state detection device 4 that the telephone set 2a is busy. Is affirmative.

Then, a busy tone is transmitted from the originating side signal transmission / reception trunk 6 to the telephone set 1x.

Then, for example, a timer of 10 seconds is started (step S42). Then, it is tested in step S44 via the signal detection device 5 whether or not the telephone 1x is hooked on within 10 seconds.

Since it is not an emergency call, if the telephone 1x is on-hook within the above 10 seconds as in the conventional case, step S44 becomes affirmative and the busy tone transmission to the telephone 1x is canceled (step S45). Exit the flowchart. In this case, of course, the telephone 1x is not charged.

On the other hand, the subscriber of the telephone set 1x who knows that the telephone set 2a is busy has an urgent business.
Operate the telephone 1x within a second to obtain the ID as the telephone 1
When a code that can identify the telephone number of x, for example, a specific code such as a pre-registered abbreviated code is input, the above ID is received via the signal detection device 5 and step S4.
6 is affirmative.

When it is confirmed that the ID is normal, step S47 becomes affirmative, and a tone (or message) for notifying that the ID has been confirmed is sent from the originating side signal transmission / reception trunk 6 to the telephone 1x ( Step S48).

Then, the loop of the telephone 1x is broken (step S49), and the call back order for the telephone 1x is stored in a predetermined area of the processing memory 92 (data table (2) in FIG. 5) (step S50). The procedure shown in FIG. 3 is exited.

As described above, when the subscriber of the telephone 1x desires to make an emergency contact with the other telephone 2a, the telephone 1x is kept off-hook even when the telephone 2a is talking. When 10 seconds have passed in this state, step S43 becomes affirmative, and after the busy state of the telephone 2a is released, the connection order for connecting the telephone 2a and the telephone 1x is determined in the predetermined area of the processing memory 92 (the data table of FIG. 1)) (step S51).

Then, the charge start time is stored in a predetermined area of the processing memory 92 (step S52), and the charging is started from this time. It should be noted that a tone different from the busy tone or a message notifying that the charging is being performed may be transmitted from the time the charging is started. Then, the procedure shown in this flowchart is ended.

Since the connection order in step S51 is charged rather than the call back order in step S50, priority is given as follows.

That is, as described above, in step S7 of FIG.
The call between a and 2a is released, and the charging process is executed in step S9. After this operation, it is tested whether or not the data table (1) for the telephone 2a stores an ID relating to the telephone number of the person called during the call (step S10). If the ID is stored in the data table (1), step S10 becomes affirmative, and the ringing tone is sent from the receiving side signal transmission / reception trunk 7 to the telephone set 2a (step S11).

When the response of the telephone set 2a is detected through the state detection unit 4 (step S12), the control unit 8 connects the telephone set 1x waiting for the call in the off-hook state and the telephone set 2a so that the telephone set can be called. (Step S1
3).

When the on-hook of the telephone 1x which is being charged is detected by the signal detecting device 5 due to the end of the call (step S14), the call end time is stored in the processing memory 92 (step S15). , Count the number of times for billing, and total the total number of bills 91 with the telephone 1
The data is stored in a predetermined area of x (step S16).

Subsequently, the highest priority ID stored in the data table (1) which has been used as described above.
Erase (data about 1x telephone) (step S
17) and returns to step S10 described above.

When the ID of the next rank of 1x is stored as the highest priority data in the data table (1), the above-described operation corresponding to this ID is repeated.

If this ID is not stored, step S10 is negative and the next step S18.
And move to the above data table (2) for the telephone 2a.
Test if D is stored. If the ID is not stored, this step is negative and the procedure shown in this flowchart is ended.

If the above-mentioned ID is stored, step S18 becomes affirmative, and at the next step S19, the telephone having the ringing tone as the highest priority from the calling side signal transmission / reception trunk 6, for example, the telephone shown in the data table (2) of FIG. 1
to n. At the same time, a ringing tone is sent from the destination signal transmission / reception trunk 7 to the telephone set 2a (step S2).
0).

When the responses of the telephones 1n and 2a are detected (steps S21 and S22), the control device 8 connects the telephones 2a and 1n via the communication path device 10 so that the telephones can communicate (step S23). Further, the call start time is stored in the processing memory 92 for billing (step S24).

Since the ringing tone is transmitted to the two telephones as described above, when one of the telephones is off-hooked first, the present embodiment is configured to transmit the ringback tone to the telephones. However, the flowchart of this part is omitted.

When the mutual call ends and the on-hook of the telephone 1n to be charged is detected, the call end time is stored in the processing memory 92 and the frequency is calculated as described above (steps S25 to S27).

Further, in step S28, the highest priority ID (for the telephone 1n in the above example) of the data table (2) is erased and the process returns to step S10.

The above-mentioned operation is performed in the ID of the data table (2).
Is repeated until all the data are erased, and the procedure of this flowchart is completed.

As described above, if the calling telephone transmits the ID when the calling telephone is busy and then waits on-hook, the above-mentioned calling is issued when the called telephone of the called party is released. Call back the side phone.

Therefore, the calling side telephone and the called side telephone that was busy are in a call state.

However, at what time the called party telephone that is busy cancels the call, the calling party telephone side does not know, and the calling party telephone side sometimes goes out and can wait for call back forever. Not necessarily.

Therefore, in the present application, it is possible to set the waiting time after transmitting the ID from the calling telephone as described above. This operation will be described with reference to the flowchart of FIG.

In FIG. 4, steps S46 and S50 are the same as the steps shown in FIG. 3, and step S60 for inputting the time code during this step, and the on-hook of the calling side telephone (for example, 1n described above) is detected. Steps S61 and S63, and steps S62 and S for storing the time code in the processing memory 92 after this on-hook.
64 has been inserted. In this case, step S49 of FIG. 3 becomes unnecessary.

When the on-hook of the calling side telephone (1n) is detected without receiving the time code from the calling side telephone (1n), step S60 is negative and step S63 is affirmative. For example, “15 minutes” is stored in the processing memory 92 as a predetermined value (default value) as a code.

On the other hand, when, for example, "# 30" is received as the time code from the telephone 1n, "30 minutes" is stored in the processing memory 92 as the standby time of the telephone 1n.

The control unit 8 refers to the time code stored in the above-mentioned processing memory, and as described above, the telephone 1n.
It controls whether to call back the side, but the flowchart at this time is omitted.

【The invention's effect】

(1) As described above, when the called party's telephone is busy, the following charges are made even when the telephone is off-hook. However, if your telephone is kept off-hook, the other party's busy is released when the other party's busy is released. The phone is connected to your phone. Therefore, it is not necessary to dial the other party's telephone many times as in the conventional case.

(2) When the called telephone sends an ID for identifying his / her own telephone while busy, and then goes on hook, the called telephone will call back when the called telephone is released. The charge at this time is reasonable for the charge since it becomes a burden on the user after the call is made, and it is not necessary to dial the other party's telephone many times.

(3) Also, the above (1) and (2) can be selected by the telephone subscriber. That is, since (1) above is prioritized over (2), if the other party's telephone is busy and there is an urgent matter, the charge will be high, but it is also possible to select (1) above. is there.
