Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a calling method in a telephone device connected to an ISDN network, and in particular, the present invention relates to a calling method in a telephone device connected to an ISDN network. This invention relates to a calling method when making a call again to the same party as the party to whom the telephone call ended.

[Conventional technology]

Conventionally, when you make a call and the other party does not respond or the other party is busy, you have to stop the call operation and make a re-call to the same party, or when you call the other party (hereinafter referred to as "outgoing call"). If you want to call the same destination again after a call (referred to as a call) has ended, you can use the redial button by memorizing the phone number of the other party that was dialed just before the call. A repeat dialing system is known that allows dialing to be made to the same destination by a simple operation.

[Problem to be solved by the invention]

In the conventional redialing method described above, a call can be made by operating the redial button only if the previous call was an outgoing call, and the call is made in response to an incoming call (hereinafter referred to as an incoming call). If you make a call to the same destination after the end of the call, the conventional redial method described above is not effective.

In view of the above, the present invention provides a calling method that allows calls to be made easily to the same destination after an incoming call ends, or a call method that allows calls to be made easily to the same destination both after an outgoing call and after an incoming call ends. The challenge is to find a transmission method.

[Means to solve the problem]

In the ISDN network that is being constructed recently, it is possible to receive a service in which the telephone number information of the caller is sent when a call is received.The present invention focuses on this service and
The telephone number information of the caller sent from the SDN network is memorized, and when making a call to the same party after the incoming call ends, dialing based on the memorized telephone number information is performed by operating the telephone number withdrawal operation means. It is designed to send signals to the ISDN network.

In addition to the above, the called party number information sent to the ISDN network when making a call is stored, so that the same operation can be used to make a call to the same party after the call has ended.

[For production]

The telephone number information of the calling party sent from the ISDN network when a call is received is stored in the storage means, and when the call is made to the same party as the other party of the incoming call after the incoming call is completed, the telephone number sending operation means is used. As a dialing signal based on the telephone number information stored in the storage means is automatically sent by the above operation, it is extremely easy to make a call again, and there is no fear of incorrect dialing, and the dialing signal is automatically sent out based on the telephone number information stored in the storage means. You can now make calls even if you don't know the number.

In addition, by storing the called party's telephone number information in the case of an outgoing call, it is possible to easily perform operations on the same destination regardless of whether the previous call was an outgoing call or an incoming call. and can make a call without fear of incorrect dialing.

(Embodiment) The drawings are for explaining the present invention in detail, and FIGS. 1 and 4 are block diagrams, and FIGS. 2 and 3 are diagrams showing the telephone number memory in the embodiment shown in FIG. FIG. 5 is a diagram illustrating the configuration of the telephone number memory of the embodiment shown in FIG. 4. In addition, in the embodiments described below, embodiments for a standalone telephone (telephone directly connected to a line) are explained in FIGS. 1 to 3, and embodiments for a button telephone device are explained in FIGS. 4 and 5, respectively. be done.

1st Embodiment - Embodiment of a standalone telephone in which a call can be made to the other party of the incoming call after the incoming call is completed. 7 and dial 8 are involved. That is, the telephone according to the first embodiment has l
5 S interface 1, which is a connection device with ONWA, and a central control device (hereinafter referred to as CP) that controls all telephones.
It's called U. ) 2. Storage means for storing the caller's telephone number information sent on the D channel (data channel) via the telephone line of the ISDN network, specifically a telephone number memory 3 composed of RAM; It has a telephone number sending operation means for sending dial data based on the telephone number information stored in the telephone number memory 3, specifically a telephone number sending button 4 constituted by a push button switch,
In addition, although not directly related to the operation of the present invention, there is also a telephone communication network 5 including a copier, a handset 6, etc.

As shown in FIG. 2, the telephone number memory 3 is constructed using, for example, seven addresses of a RAM in which one address is composed of 8 bits, and the first four bits and the last four bits of each address correspond to one part of the telephone number. Assigned to digits. Therefore, in the embodiment, it is possible to store up to 14 digits of telephone number information. In the example, the number information of each digit is as follows: the first half of the address "1" is the first digit, the second half is the 'J42 digit, the first half of the address "2" is the third digit, and the second half is the fourth digit -111. It is now stored.

When your phone receives a call from the ISDN network, the phone line's D
In addition to the incoming call data being sent by the channel, the caller's telephone number information is also being sent by the D channel. This incoming call data and telephone number information are separated and extracted at the S interface 1 and sent to the CPU 2.
Upon receiving the incoming call data, the PU 2 causes a tone ringer (not shown) to sound to indicate the incoming call, and also stores the sent telephone number information of the caller in the telephone number memory 3. For example, if the caller's phone number is "814-512"
3", data as shown in FIG. 2 is stored in the telephone number memory 3. At this time, if telephone number information is already stored in the telephone number memory 3, the telephone number information is is rewritten to the telephone number information related to the new incoming call.

After the incoming call ends, if you want to talk to the other party of the incoming call again, press the telephone number sending button 4'' after turning off the footer.

When the CPU 2 detects that the telephone number sending button 4 is pressed, the CPtJ2 reads the telephone number information stored in the telephone number memory 3, creates dial data based on this, and transmits it to the S interface. The S interface 1 transfers the dial data sent from the CPU 2 to the D channel of the telephone line and sends it to the IS via the telephone line.
Send to DN network. When making a call to the same party as the party to whom the incoming call was terminated as described above, the call can be made reliably and without error by simply pressing the telephone number sending button 4.
Moreover, the caller can make a call even if he or she does not know the telephone number of the other party.8
is possible.

Second Embodiment 1 An embodiment of a stand-alone telephone in which a call can be made to the destination of the previous call regardless of whether the call is an incoming call or an outgoing call. The dial 8 is newly involved, and the telephone number memory 3 stores not only the calling party's telephone number information from the ISDN network but also the called party's telephone number information sent by the dial 8 when making a call. The point is that it is like this.

That is, when the operator of the telephone dials the telephone number of the other party using the dial 8 when making a call, the CPU 2 sends dial data based on the dialed telephone number to the S interface 1, and from the S interface 1, the above-mentioned The dial data is sent to the ISDN network in the same manner as in the first embodiment. Simultaneously with the above operations, the CPU 2 stores and stores the telephone number information from the dial 8 in the telephone number memory 3. At this time, if there is already stored telephone number information, the telephone number information is updated to new telephone number information as in the first embodiment.

Further, as in the first embodiment, the CPU 2 also stores in the telephone number memory 3 the telephone number information of the caller sent from the ISDN network when an incoming call is received. In other words, the telephone number memory 3 stores the telephone number information of the party of the last telephone call, regardless of whether the call is an incoming call or an outgoing call.

After the call ends, if you want to talk to the other party again, press the phone number sending button 4 and the first
Dial data based on the telephone number information stored in the telephone number memory 3 is sent to the ISDN network in the same manner as in the embodiment, so that it is possible to make a telephone call to the other party.

This second embodiment has the advantage that a call can be made without error to the same party as the previous call, regardless of whether the previous call was an outgoing call or an incoming call.

Third embodiment: In the first embodiment or the second embodiment, even if a new incoming call or a new outgoing call occurs, the telephone number memory 3
The third embodiment is different from the first or second embodiment in that the telephone number information stored in the telephone number memory 3 is not updated. A telephone number storage operation means to be operated when wishing to save the telephone number information that has been received (prohibiting rewriting by newly arrived telephone number information), specifically a telephone number storage button 7 composed of a push button switch. is newly related, and a flag bit for storing the telephone number is added to the telephone number memory 3. As will be described later, the function of the telephone number save button 7 can also be added to the telephone number send button 4, and in this case, the telephone number save button 7 becomes unnecessary.

As shown in FIG. 3, the telephone number memory 3 is a RAM similar to the telephone number memory 3 of the first embodiment or the second embodiment.
It is configured using eight addresses, and address “1”
For example, the first bit F is assigned to a flag for saving the telephone number, and the address “2” to address °゛8°
° indicates telephone number information (1st to 14th digits) corresponding to addresses “1” to “7” in the configuration shown in Figure 2, respectively.
(column) is assigned to storage. The storage example of telephone number information shown in Figure 3 is the same as the data storage example of Figure 2.
14-5123'' is stored.

The calling party's telephone number information or the called party's telephone number information is stored in the telephone number memory 3 in the same manner as in the first embodiment or the second embodiment.
Before storing the telephone number, the CPU 2 checks whether a flag is set in the flag area of the telephone number memory 3, that is, whether the bit F is "1" or "0".

When the above bit F is "0", the CPU 2 transfers the telephone number information stored below the address "2" of the telephone number memory 3 to the new incoming call or Rewrite to the phone number information related to the call.

After an incoming call or an outgoing call ends, if you want to keep the phone number information of the other party of the call even after another call occurs, press the phone number save button 7 before the next incoming or outgoing call. Press down.

When the telephone number save button 7 is pressed, the CPU 2 reads this and sets bit F of the telephone number memory 3 to "1". That is, a save flag for telephone number information is set.

If there is an incoming or outgoing call after the save flag is set, the CP
U2 identifies that bit F of the telephone number memory 3 is "1", and therefore does not perform the operation of rewriting the telephone number information.

That is, the telephone number information stored in the telephone number memory 3 is preserved as is even when a new call is received or made.

To cancel the storage of the above phone number information, press the phone number storage button 7 again (in this sense, the button 7 is a phone number storage/cancellation button), and the CPU 2
reads this and sets bit F of telephone number memory 3 to “0”.
”.After that, when there is an incoming or outgoing call, the phone number memory 3
The stored information is rewritten with new incoming or outgoing telephone number information.

The phone number memory 3 is sent by operating the phone number send button 4.
The operation when making a call to the destination of the telephone number information stored in is the same as in the first embodiment or the second embodiment.

Next, an embodiment will be described in which the function of the phone number save button 7 is also added to the phone number send button 4 (in this sense,
The button 4 is a phone number send/save button. ).

Whether the pressing of the telephone number sending button 4 is an operation for sending a telephone number or an operation for storing telephone number information is determined by the CPU 2 based on the state of the telephone at the time of pressing. That is, when the telephone number transmission button 4 is pressed while the telephone is in a calling state (generally when the handset 6 is in a state where a call is not made and is picked up), the CPU
2 determines that the call operation to the destination of the telephone number information stored in the telephone number memory 3 has been performed based on the two conditions of the calling state and the pressing of the telephone number sending button 4, and stores the telephone number information in the telephone number memory 3. The dial data corresponding to the stored telephone number report is sent to the TSDN network via the S interface.

Additionally, if the phone presses the phone number sending button 4 at any point between the start of a call and the start of the next call,
The CPU 2 assumes that the operation to save the telephone number information has been performed under two conditions: a non-call state (-generally, the handset 6 is put down) or a call state, and the telephone number sending button 4 is pressed. Then, bit F of the telephone number memory 3 is set to "1" and the data stored in the telephone number memory 3 at that time is saved. Bit F of telephone number memory 3 is set to 0'' after one subsequent call, and by doing so, there is no need to perform an operation to release the save.However, if the telephone number information of the same call destination If you want to continue saving,
Each time a call is made, it is necessary to repeat the pressing operation of the telephone number sending button 4 at any time from the start of the call to before the start of the next call.

In addition, in the above method of saving phone number information by operating the phone number sending button 4, pressing the phone number sending button 4 during a call is considered to be a saving operation, and pressing the phone number sending button 4 while a call is not made is a saving operation. CP to judge it as manipulation
By setting the U2 software, it is possible to continuously save telephone number information.

Fourth embodiment: An embodiment equivalent to the first embodiment in a button telephone device The key telephone device according to the fourth embodiment has one main device M and a plurality of (n ) telephones T1 to T
The main device M includes an S interface 11 having the same function as the S interface 1 in the embodiment of the single telephone, and a central control device (hereinafter referred to as CPU 4) that controls the main device M all at once. 12. A telephone number memory 13 having the same function as the telephone number memory 3 in the above embodiment;
It has a buffer memory 14 for temporarily storing the telephone number information of the caller sent from the ISDN network when a call is received, and a switch 15 for selectively connecting the telephone line to any of the telephones T1 to T.

Further, the telephones T1 to T, . 23. Handset 24. It has a phone number save button 25, a dial 27, etc. Incidentally, in this fourth embodiment, the telephone number save button 25 is not required.

The telephone number memory 3 of the main device M is provided with storage areas E1 to En for telephone number information corresponding to each telephone T1 to To, as shown in FIG.
E7 has the same structure as the telephone number memory 3 shown in FIG. 2 above.

The buffer memory 14 may basically have the same configuration as the telephone number memory 3 shown in FIG. 2), a structure having addresses that are integral multiples of the structure shown in FIG. 2 is used. The number of addresses in the buffer memory 14 is determined by the estimated maximum number of simultaneous incoming calls calculated from the number of lines accommodated in the key telephone device (for example, if the estimated maximum number of simultaneous incoming calls is 3, the memory 14 shown in FIG. ).

When a call is received from the ISDN network via the telephone line, the caller's telephone number information sent via the D channel of the telephone line is sent to the S of the main device M by the same operation as in the first embodiment. Separated and extracted at interface 11 and CPU1
2 is sent out. Upon receiving the telephone number information, the CPU 412 stores it in the buffer memory 14.

On the other hand, the CPU 12 detects incoming data from the ISDN network and sends out incoming information to each telephone meter device n via the control line C. The CPU 21 of each telephone meter device n reads the above incoming call information and displays the incoming call on a display means (not shown).

When the #1 telephone T1 responds to the above-mentioned incoming call, for example, the CPU 21 of the #1 telephone T1 detects the response and sends response information to the main device M via the control line C. In the main device M, the CPU 12 reads the response information from the #1 telephone, controls the switch 15, and connects the B channel (information channel) where the call was received to the #1 telephone T1. As a result, the B channel where the telephone line call was received is connected to the communication network 23 of #1 telephone T1, and #1
Incoming calls can now be made on the telephone T1.

Further, when the CPU 12 of the main device M reads the response information from the #1 telephone T1, the CPU 12 of the main device M reads the response information from the #1 telephone T1.
The caller phone number information stored in 4 is transferred to phone number memory 1.
3 and stored in the area E1 assigned to the #1 telephone T1. By the above operations, the destination telephone number information of the incoming call to telephone number 11 has been stored.

Next, when making a call from the #1 telephone T1 to the same destination as the incoming call, the telephone number sending button 22 is pressed after hook-off. Through the above operations, the CPU of the main device M is connected via the control line C from the CPU 21 of the #1 telephone T1.
12, the off-hook information and the press information of the telephone number sending button 22 are sent, and the CPU 12 selects the vacant B channel of the telephone line based on the above-mentioned off-hook information, controls the switch 15, and sends #1 telephone T1 to the above of the telephone line. It connects to the selected B channel, reads telephone number information from area E1 corresponding to #1 telephone T1 of telephone number memory 13, and sends corresponding dial data to S interface 11. S interface 1
1 carries the dial data sent from the CPU 12 onto the D channel of the telephone line and sends it out to the ISDN network. With the above operations, the outgoing call operation to the same destination as the incoming call is completed.

Furthermore, when an incoming call is transferred to another telephone, the telephone number information of the other party of the incoming call is also stored in the transferred telephone.

That is, for example, if an incoming call being made on #1 telephone T1 is transferred to #2 telephone T2 by known operation and control, #2 telephone T2 first calls #1 via an extension line (not shown). After talking to the telephone T1, a response is made to the incoming line (at this time, the incoming line is on hold). As a result, the hold response information is sent from the zTL talk In T2 to the main device M, and the CPU 12 identifies that this hold response information is sent from the #2 telephone 1%lT2 and controls the switch 15. , the B channel related to the incoming call is switched from #1 phone! 117. to “2 phone T,” and the phone number information stored in area E1 of the phone number memory 13 is transferred to area E2 corresponding to 112 phone T2. Transfer to. As a result, the phone number sending button 22 is pressed on the transferred #2 phone T2.
By pressing , you can re-call the person you made the incoming call to.

In addition, in the process of transferring telephone number information in the telephone number memory 13, if the telephone number information in the transfer source area El is left as is, the transfer source #1 telephone TI and the transfer destination #2 telephone T2 It is possible to make a re-transmission to the same destination from both sides using the above method.

Fifth Embodiment: An embodiment equivalent to the second embodiment in a button telephone device. In the fifth embodiment, the telephone number information of the called party dialed from each telephone T1 to Tn when making a call is also It is stored in the telephone number memory 13 of the main device M in the same way as the calling party's telephone number information.

That is, for example, when hooking off with #1 telephone T1 and dialing the telephone number of the other party (called party) using the dial 26, the CPU 21 sends telephone number information of the called party to the main device M via the control line C. , in the main device M, the CPU
The M12 receives the telephone number information and sends dial data to the S interface 11, and the CPUv12 stores the telephone number information in the area E1 of the telephone number memory 13 corresponding to the #1 telephone T1. This makes it possible to make a call to the same destination using the telephone number sending button 22 even if the previous call was an outgoing call.

The operations of the fifth embodiment other than those described above are easily understood from the operations of the first to fourth embodiments, and therefore will not be explained again.

Sixth embodiment: An embodiment equivalent to the third embodiment in a button telephone device In the sixth embodiment, each telephone T1 to To is provided with a telephone number save button 25, and the main device M has a telephone number memory. 13 are areas E1 to E corresponding to each telephone T, to Tn;
are each constructed in the same manner as the telephone number memory 3 shown in FIG. 3 above. That is, a bit F for setting a flag for storing telephone numbers is provided at the first address of each area E1 to En, and telephone number information is stored sequentially from the second address in each area.

When the phone number save button 25 is pressed, the CPU 21
sends the press information of the button 25 to the CPU 12 of the main device M via the control line C, and the CPU 12 receives this information and selects the area of the telephone number memory 13 corresponding to the telephone on which the above operation was performed. For example, if #1 telephone T1 is operated, area E of telephone number memory 13! The flag bit F set at the start address of is set to "1". This prohibits the telephone number information stored in area E1 of the telephone number memory 13 from being updated with newly arrived telephone number information. That is, the already stored telephone number information will be saved. To cancel the storage of this phone number, by pressing the phone number storage button 25 again, the same control as in the third embodiment is used (however, information on pressing the phone number storage button 25 is transmitted to the main device M. ), the storage is canceled.

Further, in this embodiment of the button telephone device, the control form is similar to that of the third embodiment, so that the telephone number sending button 22 is used to perform the saving operation of telephone number information, and the telephone number save button 25 is eliminated. Can be done.

That is, as in the case of the third embodiment, the difference in the state of the telephone (the telephone on which the pressing operation was performed) when the telephone number sending button 22 was pressed (uncalled state, in call state, or outgoing state) It is determined whether the pressing of the telephone number sending button is for dialing 8 or for saving or unstoring the telephone number information. This determination may be made by the telephones T1 to To, or may be made by the main device M. That is, when using telephones T, to Tn, CP
Telephone T when the telephone number sending button 22 is pressed in U, 21
1~T.

The CPU 21 determines the state of the CPU 21 and creates save information or save release information for the call information and telephone number information, and sends this to the CPU 12 of the main device M via the control line C. The CPU receives this and performs call control, storage control or storage release control of telephone number information. In addition, when performing this on the main device M, the telephones T1 to To send press information of the telephone number sending button 22 to the CPU 12 of the main device M via the control line C, and the CPU of the main device M receives this information. Then, from the state of the telephones T1 to Tn at that time (the state of the telephones T1 to To is always monitored by the CPU of the main device, it is a general control of the button telephone device, and when the telephone number sending button 22 is pressed, (Generally, there is no need to send information indicating the status of the telephones T1 to To to the main device M.) The determined control, that is, call control, telephone number information storage control, or storage cancellation control is performed.

Operations other than those described above in the sixth embodiment can be easily understood from the operations of the first to fourth embodiments, and therefore will not be explained again.

〔Effect of the invention〕

As explained above, in the present invention, when receiving a call, the ISDN
The telephone number information of the caller sent from the network is stored, and when a call is to be made again to the same party after the incoming call is completed, the call can be returned by operating the telephone number sending means. With simple operations, you can reliably call back without dialing incorrectly, and as long as you only call back after an incoming call, you can make a call without knowing the telephone number of the other party.

In addition to the above, the present invention also stores the telephone number of the other party (called party) dialed when making a call, so that after the call ends, when talking to the same party, Regardless of whether the previous call was an outgoing call or an incoming call, it is possible to make a call with a simple operation.

In addition to the above, the present invention enables the telephone number information of the other party stored in the telephone device to be saved with a simple operation regardless of subsequent calls.
