Abstract

PURPOSE:To improve the calling operability by executing the dialing by other dial number information automatically when the connection is disabled by dialing of one number information among plural sets of dial number information possessed by a communication opposite party. CONSTITUTION:If it is discriminated by a connection state informing means B that the connection by the dialing of the 1st dial number information is disabled, the command of duplicated dialing by a caller operator is awaited, and when the command of the duplicated dialing is inputted, after the line is opened automatically and the redialing is applied according to the 2nd dial number information stored in the dial information memory A. The calling operator stores plural sets of dial number information possessed by a desired communication opposite party in the dial information memory A in advance corresponding to one subscriber selection key and when one subscriber selection key is operated corresponding to the communication opposite party and the connection is disabled, the dialing is applied automatically by having only to input the duplicated dialing command by the duplicated dialing input means C. Thus, the operation relating to the redialing is remarkably simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an improvement in a communication terminal device having an automatic dialing function.

(Prior Art) In recent years, many communication terminal devices such as telephone devices and facsimile devices are equipped with an automatic dialing function. This automatic dialing function, for example, stores the telephone number of the desired communication partner in advance in the dialing information memory in association with the registered number, and is activated when any registered number is input using the dial key or subscriber selection key. A telephone number to be received is read from the dial information memory, and a dial signal consisting of a dial pulse or a DTMF signal is generated in accordance with the telephone number and sent to the line. Therefore, when using a device equipped with this type of calling function, the subscriber can register the telephone number of the desired communication partner in advance in the dialing information memory, and then enter the registered number with one touch or a few digits when making a call. It is very convenient because you can make a call with simple operations just by inputting the information.

On the other hand, in recent years, with the increase in communication demand, various communication networks such as second subscriber communication networks and dedicated communication networks have been constructed in addition to subscriber telephone networks. The communication network can be selectively used by sending a dial signal according to a preset telephone number.

In addition, recently many subscribers have multiple terminals depending on the communication partner, such as large business establishments and offices, and when making a call to such a communication partner, there may be times when there are no available terminals. You can make a call by selecting the terminal that is marked.

However, the conventional communication terminal device equipped with the automatic dialing function always associates one communication network or terminal with one subscriber selection key and stores that telephone number in the dialing information memory. When making a call to a communication party that can use the telephone numbers of multiple communication networks or terminals as described above, select one of the communication networks or terminals for which the telephone number has been registered in advance in association with the subscriber selection key. Automatic dialing could only make calls to one communication network or terminal. Therefore, if the communication network from which the auto-dial call was made is in use or the other party's terminal is in use, the user can temporarily release the line by taking the handset off-hook, and then manually switch to another communication network or The call operation was extremely troublesome as the user had to enter the phone number of the terminal to make a call.

Additionally, in order to be able to make automatic dial calls to any communication network or terminal, it is also possible to store the telephone numbers of each communication network or terminal in association with different subscriber selection keys. However, since the number of subscriber selection keys is limited, this method reduces the number of communication partners to whom automatic dialing can be made, which is extremely undesirable.

(Problems to be Solved by the Invention) As described above, the conventional device is difficult to use when re-calling the same communication partner using a different communication network or re-calling another terminal owned by the communication partner. The calling operation is troublesome because the subscriber has to do everything manually, and if each communication network or terminal is made to be able to perform automatic dialing individually, the number of communication parties to whom automatic dialing can be made is small. However, the present invention focuses on this point, and does not limit the number of communication parties that can be automatically dialed, and moreover, only dials one of the plurality of dial number information possessed by the communication party. If a connection cannot be established due to a call made using number information, a call can be made automatically using other dial number information.This allows for a large number of communication parties that can be automatically dialed and eases the call operation. The present invention aims to provide a communication terminal device with good performance.

[Structure of the Invention] (Means for Solving the Problems) As shown in FIG. 1, the present invention provides a dial information memory A that stores a plurality of pieces of dial number information owned by a desired communication partner, respectively. , a connection state notification means B that notifies the calling operator of the state of the communication network after sending the dial signal, and the above-mentioned call operation in which it is determined by the connection state notification means B that connection to the communication partner is impossible. a multi-call instruction input means for a person to instruct a multi-call; first and second dial sending means; The dial sending means selectively reads the first dial number information among the plurality of corresponding dial number information from the dial information memory A, and sends the dial signal corresponding to this dial number information to the communication network after capturing the line. , when the communication network becomes unconnectable after sending the dial signal in parentheses and a multi-call instruction is input by the multi-call manual means C, the second dial sending means E releases the line; The second dial number information is selectively read out of the plurality of dial number information corresponding to the communication partner from the dial information memory, and the dial signal corresponding to this dial number information is sent to the communication network after the line is captured. This is what I did.

(Function) As a result, if it is not possible to connect due to the call originating from the first dial number information, the system waits for a multiple call instruction from the caller and automatically calls when the multiple call instruction is input. After the line is released, the call will be made again according to the second dial number information stored in the dial information memory A, so the calling operator will be able to confirm that the desired communication party has the information in the dial information memory A. By associating multiple dial number information with one subscriber selection key and storing it in advance, it is possible to operate one subscriber selection key corresponding to the communication partner and issue a duplicate call instruction when connection is impossible. Just by inputting the information, not only a call based on the first dial number information but also a call based on the second dial number information will be automatically made, which greatly simplifies the operation related to re-calling. Furthermore, as mentioned above, multiple dial number information owned by a desired communication partner is stored in association with one subscriber selection key, so the number of communication partners corresponding to the number of subscriber selection keys is automatically dialed. It is possible to register for outgoing calls, which improves service quality.

(Embodiment) FIG. 2 shows the configuration of a telephone device which is a communication terminal device in an embodiment of the present invention.

This device is broadly divided into a telephone section and an automatic dialing section, which are alternatively connected to an exchange-like subscriber line 1 (not shown) through switching relay contacts 2. First, the telephone unit includes a telephone circuit 3, a transmitter 41, and a receiver 42.
The device is comprised of a handset 4 with a built-in device, and a hook switch 5 that is linked to the hook operation of the handset 4.

On the other hand, the automatic dialing device section has a control circuit 6 consisting of, for example, a microcomputer. This control circuit 6 is composed of a main control section (CG) 61, a ROM 62 that stores its operating program, and an input section 63 and an output section 64 consisting of an I10 port. Operation signals of the provided dial key 71, subscriber selection key 72, redial key 73, pause key 74, hooking key 75, registration key 76, call switch 77, and double call key 79 are input.

Note that 78 is a hook contact that generates a hook signal in conjunction with the on/off operation of the hook switch 5 and inputs it to the control section 6. Further, the control circuit 6 is attached with a RAM 8 as a dial information memory. This RAM 8 is, for example, the third
As shown in the figure, in areas corresponding to each key of the subscriber selection key 72, telephone numbers of a plurality of communication networks to which the communication partner can be connected are stored for each communication partner. still,
Reference numeral 81 is a backup power supply for the RAM 8 in case of a power outage.

On the other hand, the output section 64 of the control circuit 6 outputs drive control signals to the DTMF signal generation circuit 9, relay drive circuit 10, light emitting diode 18, and liquid crystal display 19, respectively. First of all, the DTMF signal generation circuit 9
F (Dua ITone Multi Frec
+uency) signal, and this DTMF signal is sent to the subscriber line 1 via the line transformer 12, the switching relay contact 2, and the dial contact 11, respectively. Further, the relay drive circuit 10 operates the switching relay contact 2 and the dial contact 11 for transmitting dial pulses in accordance with the drive control signal from the control circuit 6. Furthermore, the light emitting diode 18 lights up in response to the dial signal sending operation, thereby notifying the user that the dial signal is being sent. Further, the liquid crystal display 19 displays the connection state of the exchange determined from the detection results of the signal detector 13, which will be described later, in characters, especially the busy state. Furthermore, a signal detector 13 is connected to the subscriber line 1. This signal detector 13 detects signals representing the exchange connection status, such as dial tone, busy tone, ringback tone, etc., arriving from the exchange after sending the dial signal, and outputs the detection signal to the control unit 6. . Note that 14 is a loudspeaker receiving circuit used during on-footer transmission, and is composed of an amplifier 15, a speaker 16, and a mute circuit 17.

By the way, the control circuit 6 includes dial number registration control means 65, first dial transmission control means 66, and second dial transmission control means 67 as shown in FIG. 4 as control means related to the calling operation. ing. First, with the registration mode designated by the operation of the registration key 76, the dial information registration control means 65 selects a telephone number for each communication network for a desired communication partner in association with an arbitrary key of the subscriber selection key 72. When these telephone numbers are input, these telephone numbers are prioritized and stored in storage areas corresponding to the subscriber selection keys of the RAM 8, respectively. Note that this priority order is set, for example, in the order in which telephone numbers are input. The first dial transmission control means 66 also controls the subscriber selection key 72.
Alternatively, when the redial key 73 is operated, it performs capture control of the subscriber line 1, reads out the telephone number with the highest priority from the storage area corresponding to the subscriber selection key 72 in the RAM 8, and The dial pulse or DTMF signal according to the number is sent to dial contact 11 or D.
The TMF signal is generated from the TMF signal generating circuit 9 and sent to the exchange via the subscriber line 1. Further, the second dial sending control means 67 determines whether or not a tone detection signal is detected from the signal detector 13 after the first dial sending controlling means 66 sends out the dial signal. If a busy tone detection signal is being output, the operation of the heavy call key 79 is monitored, and when the heavy call key is operated, the switching relay contact 2 is switched to temporarily release the subscriber line 1 and set to a predetermined setting. After a pause period of It is sent to the exchange via line 1. If the second dial transmission control means 67 is busy again after transmitting the dialing signal by the telephone number having the second priority, the second dial transmission control means 67 will operate the multi-call key 79 to dial the telephone number having the third priority. Read and perform re-call control. In other words, the RA is used until a connectable communication network is found.
Each telephone number stored in M8 is selected according to the priority order, and automatic dialing control is performed for each telephone number.

Next, the operation of the device configured as described above is controlled by a control circuit 6.
This will be explained according to the control procedure. The following description assumes that the RAM 8 already stores the telephone numbers of each terminal owned by a desired communication partner in association with each subscriber selection key 72, as shown in FIG. 3, for example.

In the standby state, the control circuit 6 monitors the operation of the registration key 76, monitors the occurrence of incoming calls, and monitors the occurrence of outgoing calls in steps 5a, 5b, and 5c, respectively, as shown in FIG. In this state, when the subscriber goes off-hook by picking up the handset 4 or pressing the call button 77, the control circuit 6 detects this in step 5C and proceeds to step 5d, where the switching relay contact 2 is first connected to the telephone. By switching from the department side to the automatic dialing device side, the line (subscriber line 1) is captured using the line transformer 12. Note that if the user goes off-hook by picking up the handset 4, the line is captured when the hook switch 5 is turned on. When the line is captured, the control unit 6 causes the subscriber to abandon the call and send the dial tone DT from the exchange in steps 5e and 5f, respectively.
When the dial tone DT arrives, the input operation of the dial number is monitored in step 5g.

Incidentally, if the subscriber abandons the call by performing an off-footer operation, the process moves to step 5k to release the line and then return to the standby state.

Now, when the subscriber specifies the calling party by operating the subscriber selection key 72 while the dial tone DT has arrived, the control unit 6 detects this operation in step 5g and proceeds to step 5h. Then, it is determined whether the dialing operation is manual or automatic. In this case, since automatic dialing is made by operating the subscriber selection key 72, the control section 6 moves to step 51, sets the key code of the subscriber selection key 72 to II, and sets a predetermined pause time in step 5j. Thereafter, the process moves to step 6a in FIG. Then, in step 6a, the telephone number of the communication network with the first priority is read out from the storage area of the RAM 8 corresponding to the key code of the subscriber selection key 72, and in step 6b, the dial pulse or A DTMF signal is generated from the dial contact 11 or the DTMF signal generating circuit 9 and sent to the subscriber line 1, and in step 6C, the light emitting diode 18 is turned on to notify the subscriber that dialing is being sent. Then, each time the dial signal for one digit of the telephone number is sent out, in step 6d and step 6e, the end of sending the dial signal is determined and the arrival of the busy tone BT from the exchange is monitored, and the dial signal for all digits is checked. The above dial signal transmission control is repeated until transmission is completed. In this way, a dialing signal corresponding to the telephone number of the first communication network is sent out. On the other hand, if the communication network line corresponding to the first telephone number is idle, the other party's terminal will be called via this line, and the calling terminal will receive a ring pack tone. It will be sent back. In this state, when the communication partner terminal responds by picking up the handset, the called terminal and the calling terminal are connected, and communication between the two terminals is possible thereafter.

When the call ends, the control circuit 6 detects the end of the call in step 6g, moves to step 5h, releases the line, performs predetermined call end processing, and then returns to the standby state.

By the way, if the communication network corresponding to the first telephone number is currently in use, a busy tone BT is sent from the exchange to the calling terminal. Then, the control unit 6
After stopping the transmission of the dial signal and the display during dial transmission by the light emitting diode 18, a message indicating that connection is not possible is displayed on the liquid crystal display 19 in step 61, and then, in step 6j, the operation of the double call key 79 is monitored. Do this.

Incidentally, at this time, the busy tone arriving via the subscriber line 1 is amplified and output from the speaker 16 of the loudspeaker receiving circuit 14.

Accordingly, based on the amplified busy tone and the display result on the liquid crystal display 19, the calling operator can know that the first communication network is unavailable. Assuming that the calling operator operates the multi-call key 79 within a certain period of time, the line is temporarily released in step 6, and the predetermined time necessary for the exchange to return to the standby state in step 6β has elapsed. Thereafter, in step 6m, the line 18- is again captured, and as shown in FIG. 7, in steps 7a and 7b, the call abandonment operation is monitored and the arrival of dial tone DT is monitored, respectively. And step 7d
After inserting the predetermined pause time in step 7e, RA
Read the telephone number of the second communication network from M8, and step 7
Dial pulse or DT corresponding to this phone number with f
An MF signal is generated and sent to the subscriber line 1, and in step 7Q, the light emitting diode 18 is turned on to notify the subscriber that dialing is being sent. Thus, a call is now made to the communication network corresponding to the second telephone number. Note that if the multi-call key 79 is not operated within a certain period of time after making a call to the first communication network, the control unit 6 moves from step 6j to step 6n and step 60, where each call is made. The call abandonment operation is monitored and a certain period of time is monitored, and when the subscriber abandons the call by performing an on-hook operation or a certain period of time has elapsed, step 6p
to release the line and return to standby mode.

In response to a call made using the telephone number of the second communication network, if that communication network is currently idle, 11JI1
After confirming the ringback tone coming from the exchange, the circuit 6 moves to call control in step 6f shown in FIG. 6, thereby allowing the subscriber to make a call with the communication partner terminal. On the other hand, if the communication network corresponding to this second telephone number is also in use, the control section 6 confirms this by the busy tone BT coming from the exchange in step 71, and sends out a dial signal and lights up the light emitting diode 1.
8 is stopped, and then, in step 7j, a message that connection is not possible is displayed on the liquid crystal display 19, thereby notifying the calling operator. At this time, the busy tone arriving from the exchange is amplified from the speaker 16 of the loudspeaker receiving circuit 14, thereby notifying the calling operator that the communication network is not connectable. If the caller confirms this notification and operates the multi-call key 79 within a certain period of time, the control circuit 6 detects this operation in step 7 and proceeds to steps 8a to 8m in FIG. The control then proceeds to the control shown in FIG. 2, and as in the case of calling based on the second telephone number, control for sending out a dialing signal using the telephone number of the third communication network is executed.

On the other hand, if the multiple transmission key 79 is not operated within a certain period of time, the process returns to the standby state through steps 6n to 6p in FIG.

As described above, in this embodiment, when attempting to make a call using automatic dialing to a communication partner terminal that can be connected via multiple communication networks, the communication network corresponding to the first telephone number is in use. In this case, the liquid crystal display 19 notifies the calling operator, and when the calling operator confirms this notification and operates the double call key 79, the second telephone number is automatically selected. If a dial signal is sent to that communication network and the communication network of this second telephone number is also in use, the third telephone number is automatically selected by operating the double call key 79. Since a call will be made to that communication network, the subscriber stores in advance the telephone numbers of each communication network for one communication partner terminal in the RAM 8, which serves as dial information memory, in order of priority. By memorizing it, you can simply operate the subscriber selection key corresponding to the communication partner terminal and the multi-call key 79.
Even if the communication network from which the call was made is in use, an idle communication network is automatically selected and the call can be made to this communication network. Therefore, the operability of the subscriber's call operation has been greatly improved, and the occurrence of input errors is reduced compared to conventional devices in which the telephone number had to be entered manually each time, making it more accurate. You can make calls. Further, since each subscriber selection key stores the telephone number for each communication network for one communication partner terminal, the subscriber selection key 72
It is possible to automatically dial a number of communication partner terminals corresponding to the number of keys, and thereby make it possible to make calls to a large number of communication partner terminals by automatic dialing.

Furthermore, in this embodiment, if the communication network that made the call is in use, this is detected and the fact is displayed on the liquid crystal display 19 to notify the calling operator. The person can clearly know the status of the communication network, and after confirming this notification, when the calling operator operates the multi-call key 79, he or she can select the next telephone number and dial the corresponding communication network. Since the signal is transmitted, calls using telephone numbers having the second or higher priority can be made according to the intention of the calling operator.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, an automatic dial call is made to a communication partner terminal that can be connected via multiple communication networks, but an automatic dial call is made to a communication partner who owns multiple terminals with different telephone numbers. It may be applied when doing so.

Further, the name of the communication party being called and the type of communication network may be displayed on the liquid crystal display. If you do this,
The subscriber can clearly know which communication partner is being called via which communication network. In addition, the type of communication network, the configuration of the connection status notification means and the multiple call instruction input means, the control procedure and control contents of the first and second dial sending means, the configuration and storage form of the dial information memory,
The type of communication terminal device (it may be a data communication device such as a facsimile device), etc. can be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, there is a dial information memory storing a plurality of pieces of dial number information owned by a desired communication party, and a communication network after sending a dial signal. A connection status notification means for notifying the calling operator of the status, and a double call manual for the calling operator to instruct multiple calls if the connection status notification unit determines that connection to the other party is impossible. means, first and second
dial sending means, when a call request to the communication partner is input, the first dial sending means reads the first dial number information from among the plurality of corresponding dial number information from the dial information memory.
