[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device which receives information capable of identifying a calling party when receiving a call.

[0002]

2. Description of the Related Art In U.S. Pat. No. 3,904,830, a telephone number of the calling side is sent from the calling side upon reception of an inquiry signal from the called side, and the telephone number is called by the called side. A telephone device capable of displaying a number is disclosed.

In addition, an IN called "INS Net 64" or "INS Net 1500" of Nippon Telegraph and Telephone Corporation.
Among the DN services, there is a basic service called "caller ID notification". This service sends the telephone number of the calling side to the called side from the Internet, and if this number is displayed on the called side, it becomes easy to identify the calling side.

[0004]

In the conventional device of this type, the telephone number of the calling side can be simply known.
On the contrary, when making a call to the calling side, it is necessary to dial the above telephone number one by one. In many cases, it is not possible to identify the person on the calling side only by the telephone number of the calling side.

As a method for solving such a problem,
There is a method proposed in Japanese Patent Application No. 4-299956 filed by the applicant of the present application on Nov. 10, 1992.

According to this method, the telephone number of the calling side sent at the time of an incoming call is stored, automatic dialing by this telephone number is possible, and the telephone number is stored in advance in the speed dial memory. If it is the same as the stored telephone number, the information for identifying the other party stored in the speed dial memory in association with the telephone number is displayed. This makes it easy to identify the other party who received the call when he was absent. It is possible to specify and dial the other party easily.

However, even in the above-mentioned proposed method, it is still possible to specify the calling party for a telephone number which is not registered in advance in the speed dial memory.

FIG. 5 is a schematic diagram showing general call control at the time of line connection between the two terminals TE1 and TE2 connected to the ISDN network NW. Before explaining the operation of the apparatus of this embodiment, this will be described first. Call control will be described. still,
Signal transmission and reception in this call control are all performed via the D channel.

Now, when calling TE2 from TE1 with TE1 as the calling side and TE2 as the called side, first, TE1 has its own device in addition to the service information such as whether the device is a facsimile device or a telephone device. The telephone number for specifying the side, the telephone number for specifying the TE2, and call setting information such as subaddress information are transmitted to the NW as a SETUP signal. The sub-address information is originally information for individually specifying a plurality of terminals to be connected corresponding to one telephone number, but the sub-address information does not necessarily need to transmit the specific information. Information or the like for identifying the calling party may be transmitted.

Since the NW knows in advance the type of each terminal connected to this NW, when the SETUP signal is received, it is judged whether the TE1 and TE2 are the same type of device. If both terminals are different,
DI representing information indicating that connection is impossible (release completion information)
The SC signal (not shown) is returned to the terminal TE1 and the SETUP signal from TE1 is invalidated. On the other hand, TE1 and TE
When the NW determines that they are the same type of device, the NW returns the call setup information indicating that the connection is possible to the terminal TE1 as a CALL PROC signal. However, the above NW is this NW
Since the usage status of the B channel of each terminal connected to is also known, even if the terminals TE1 and TE2 are of the same type, connection is impossible when all the B channels of TE2 are in use. D indicating the information that
It sends back an ISC signal (not shown) to the terminal TE1.

Further, when the NW returns the information indicating that the connection is possible to the terminal TE1, the CALL PROC
Information for identifying the B channel used for communicating data (voice data, image data, etc.) between the terminal TE1 and the network NW is also carried in the signal and returned. If the B channel identification information is included in the SETUP signal from the TE 1 and transmitted, the SETUP signal is transmitted.
According to the data in the signal, on the other hand, if it is not included in the SETUP signal, the NW selects an unused B channel connecting to TE1 and returns it.

When a CALL PROC signal indicating that connection is possible is sent back to the terminal TE1, the NW continues to the terminal TE.
2 to the call setting signal SETUP. This SWTUP
The signal is the SETUP signal transmitted from the TE1 to the NW, to which information for identifying the B channel used for data communication between the NW and TE2 is added. still,
Whether the telephone number identifying TE1 included in the SETUP signal transmitted from the NW to the TE2 is an accurate number for identifying the TE1 when TE1 is transmitted to the NW. It is judged by the NW, and if it is not the correct number, the NW rewrites it with the correct number.

The terminal T which has received the SETUP signal from the NW
E2 determines whether or not the function required by this signal can be executed, and returns a CALL PROC signal indicating that the function can be connected to the NW if the function can be executed. A DISC signal (not shown) indicating that connection is impossible is returned to the device.

NW is a DI indicating that TE2 cannot connect.
When the SC signal is received, the DISC signal indicating that connection is impossible is transmitted to TE1, and the connection between TE1 and TE2 is invalidated.

On the other hand, when the CALL PROC signal indicating that the TE2 is connectable is returned to the NW, the TE2 notifies the user that there is an incoming call, and informs that the TE2 is in the process of being notified. The ALERT signal shown is transmitted to the NW. Upon receiving the ALERT signal from TE2, the NW transmits this signal to TE1. When the terminal TE2 becomes operable in response to the notification, the TE2
Transmits the response signal CONN to the NW, waits for reception of the response confirmation signal CONN ACK from the NW, and starts communication with the TE1.

When the NW receives the CALL PROC signal indicating that it is connectable from the TE2 and then receives the ALERT signal, the NW transfers the CALL PROC signal to the terminal TE1 and returns the CONN ACK signal to the terminal TE2. Allows data communication between terminals.

After that, the terminals TE1 and TE2 exchange data via the B channel determined by the call control. Note that this communication control is performed by the LAPB (19), not the LAPD (18).

Next, the operation of the apparatus of this embodiment will be described with reference to the flowcharts shown in FIGS. 6 and 7. The flowcharts of FIGS. 6 and 7 show the control program in the program memory (14).

In step S1 of FIG. 6, the control unit (13)
From the network side via the ISDN line (16)
LAPD (18) determines whether an ETUP signal has been sent.
Is determined by the signal from, and if not sent, the process proceeds to step S2 in FIG.

In step S2, the hook detector (24)
It is determined whether or not the handset (2) is in the picked-up off-hook state based on the detection result of 1., and if it is determined that the handset (2) is not in the off-hook state, the process proceeds to step S3.

In step S3, it is determined whether or not the key of the key input section (25) has been operated. If it is determined that the key has not been operated, the process returns to step S1.

That is, in the standby state where there is no incoming call from the line (16) and there is no operation on the handset (2) and the key input unit (25), the control unit (13) circulates through a loop consisting of steps S1 to S3. To process.

On the other hand, if it is determined in step S1 that there is an incoming call, it is determined in step S4 based on the SETUP signal transmitted as described with reference to FIG. 5 that connection is possible. If it is determined that connection is possible, LAPD (18 ), S-
CAL to ISDN line (16) via I / F (17)
While sending the L PROC signal, the user is informed of the incoming call, and the ALERT indicating this notification is given.
The signal is sent to the ISDN line (16) via the LAPD (18) and the S-I / F (17).

In the following S5 step, the telephone number of the other party (calling side) transmitted in the SETUP signal or the information for specifying the telephone number and the subaddress information (hereinafter, this information and the telephone of the calling side) The calling number information (generally called calling party information) is stored in the calling number memory (23).
Specifically, first, it is determined whether or not the calling party telephone number matches the other party telephone number registered in the speed dial memory (22), and when they match, the corresponding shorter party telephone number is shortened. The other party information stored in the dial memory (22) is stored in the other party information column of the calling number memory (23), and the speed dial memory (23) is stored in correspondence with the other party information stored in the other party information column. )
The shortened number is stored in the corresponding shortened number column of the calling number memory (23), and the sub address information is further stored in the sub address information column. Further, the date and time data when the incoming call is received is stored in the incoming call date and time column of the calling number memory (23).
The date and time data is read from a clock circuit (not shown) built in the control unit (13).

On the other hand, if it is determined that the telephone number of the calling side does not match the telephone number of the other party in the speed dial memory (22), the telephone number of the calling party is stored in the other party information column of the calling number memory (23). Is stored, a numerical value such as “99” that does not match the abbreviated number in the abbreviated dial memory (22) is stored in the corresponding abbreviated number column, and subaddress information is further stored in the subaddress information column. Even at this time, the data indicating the date and time of the incoming call is stored in the incoming call date and time column.

The calling side information is stored in the calling number memory (23) in the order of the incoming call, corresponding to the smaller numerical value of the item number.

When the processing in step S5 is completed, the processing is
Go to step 6. In step S6, it is determined whether the called side has answered. That is, the control unit (13) determines whether or not the handset (2) has been picked up in response to the notification given in step S4, based on the output from the hook detector (24).

If it is determined that there is no response in this determination, the process proceeds to step S7. In this S7 step,
It is determined whether or not the incoming call is completed. Specifically, when the calling party places the handset and terminates the call because the called party does not respond, the calling party sends a DISC signal indicating the termination of the incoming call to the called party through the ISDN network. Therefore, the presence or absence of this DISC signal is determined. If it is determined in this determination that the incoming call has not ended, the process returns to step S6.

Therefore, the steps S6 and S7 are repeated unless the caller responds to the call when the call is received and the caller does not perform the call end operation.

If it is determined in step S7 that the incoming call has been completed, the process proceeds to step S8. In step S8,
On the display unit (6), a message indicating that there is an incoming call such as "I had a telephone while I was absent." Is displayed and a flag F indicating that the message is being displayed is displayed in the following S9 step. Is set to "0". The flag F is set in the working memory (21). When the process of step S9 is completed, the process returns to step S1 and enters a standby state.

Returning to step S6, if it is determined that there is a response in this step, the process proceeds to step S10. In this step S10, each data of the destination information, the corresponding shortened number, the sub address information and the incoming call date and time stored in the calling number memory (23) by the latest execution of step S5 is erased. Therefore, the call number memory (23) stores only the information corresponding to the incoming call that the user did not answer.

In the subsequent step S11, it is determined whether or not the call has ended. Specifically, the hook detector (24)
Based on the output from, it is determined whether the handset (2) is in the on-hook state in the standby state,
Until the on-hook state, the call is regarded as being continued, and the step S11 is cycled. If it is determined that the on-hook state has been entered, the process returns to step S1 to enter the standby state.

Returning to step S2 in FIG. 7, when the off-hook state is detected in this step, the control unit (1
In 3), it is considered that the calling operation is performed, and the process proceeds to step S12.

The calling operation in step S12 is as follows. Method of entering the other party's telephone number using only the numeric keypad b. Method by reading the other party's telephone number in the speed dial memory (22) c. There are three methods, that is, a method based on the other party information in the calling number memory (23). When the ten key is input following step S2, the control unit (13) considers it to be the method a. Then, in accordance with this input, the number string output from the key input unit (25) is used as the other party's telephone number and the ISDN line (1
The LAPD (18) is controlled so as to be output as one data of the SETUP signal to the D channel of 6).

Further, when the asterisk key (4) and the numeric keypad are continuously input after the processing of step S2, the control unit (13) considers it to be the method of the above b, and the asterisk key (4) The number string input thereafter is used as an abbreviated number and the other party's telephone number stored in the abbreviated dial memory (22) corresponding to this number is read out, and LAPD (1
8) The D channel of the line 16 is output as one data of the SETUP signal from 8).

Further, when the asterisk key (4) is input twice in succession following the processing of step S2, the control unit (13) considers it to be the above method c, and as shown in FIG. The calling party's telephone number corresponding to the information pointed to by the cursor (11) in the calling side information displayed on the display unit (6) is read from the calling number memory (23) or the speed dial memory (22), The LAPD (18) causes the D channel of the line (16) to output as one data of the SETUP signal. Then, when the other party responds to this call, the information in the designated calling number memory (23) is erased. Since the display of the calling side information on the display unit (6) will be apparent from steps S14 to S16 described below, detailed description thereof will be omitted here.

When the process of step S12 is completed, the process proceeds to step S13. In this S13 step, S
It is determined whether or not the call started based on the calling operation in 12 steps is completed. Specifically, after the end of step S12, the determination of step S13 is repeated until the handset (2) is returned to the home position and the signal indicating that the hook detector (24) is in the on-hook state is output.
When the above signal is detected, the process returns to step S1 and enters the standby state.

Returning to step S3, if it is determined that an operation has been performed in this step, the process proceeds to step S14. In step S14, it is determined whether or not the flag F is "0", and if it is "0", the process proceeds to step S15.

In step S15, the calling number memory (2
The calling information in 3) is displayed on the display unit (6) as shown in FIG. 1, and the flag F is set to "1" in the subsequent step S16 to indicate that this display is being performed. Thereafter, the process returns to step S1.

On the other hand, in step S14, the flag F
When it is determined that is not "0", the process proceeds to step S17. In step S17, the operation corresponding to the key whose operation is detected in step S3 is executed. As an example, when the up / down cursor keys (9) and (10) are operated in the display state of the display unit (6) shown in FIG. 1, the cursor (11) on the display unit (6) moves up and down, and also scrolls up and down. When the keys (7) and (8) are operated, the display on the display unit (6) is scrolled to sequentially display the data in the calling number memory (23) on the display unit (6). When the clear key (12) is operated, the calling number memory (2) indicated by the cursor (11) on the display (6) is displayed.
The calling party information in 3) is deleted.

After that, the process returns to the step S1 to enter the standby state.

[0060]

According to the present invention, since the subaddress information sent as one data of the SETUP signal at the time of an incoming call can be displayed on the display section, the calling side can identify the calling side as the subaddress information at a glance. By registering the name, message, etc. of the caller, the callee can immediately and easily identify who the call came in when he was absent.

Further, the sub-address information sent at the time of an incoming call is stored in the calling number memory together with the telephone number of the calling side, and the sub-address information is stored in this memory in association with the sub-address information by simply selecting the sub-address information at the time of calling. Since it is possible to make a call using the provided telephone number, it is possible to easily make a call again to the called party after returning home even if there is an incoming call when the user is away from home or the like.

The sub-address information stored in the called number memory at the time of an incoming call is also erased from the memory when the user answers the incoming call, so that only the incoming call that cannot be answered can be reliably determined. .
