Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an improvement in a communication terminal device connected to a home bus of a digital subscriber line.

(Prior Art) In recent years, various communication network systems have been developed with the advancement of communication technology and the diversification of communication formats.
ntearrated 5 services digita
lnetwork).

This ISDN provides telephone, data, facsimile communications, and various communication processing services in a single digital communication network.A communication system that utilizes this ISDN is configured, for example, as shown in Figure 7. Ru. In other words, this system is an ISDN to which digital line switching 1!41, packet switching network 2, common line signaling network 3, etc. are connected.
This ISDN exchange 4 is connected to a digital communication network consisting of a T line (up line) and an R (down line), and a telephone device in the user's premises via the subscriber line 5's in-home bus. A communication terminal device 6 such as a facsimile device or a voice mail device is connected. And each subscriber line 5
For example, when the transmission rate is 192 bits/
sec basic interface, 64 bits/sec B
Two channels and one D channel of 16 bits per second are time-division multiplexed, and these channels are used to transmit data.

By the way, this type of system is configured by connecting a home network terminal device 7 connected to each subscriber line 5 and a communication terminal device 6 via a home bus. A maximum of eight communication terminal devices 6 can be connected. Each of these communication terminal devices 6 is configured such that the user can arbitrarily set a sub-address as terminal identification information, and when an incoming call occurs to the in-home bus, the calling side (I Search for a subaddress from the call setup message sent from the SDN exchange (on the SDN exchange side), and if there is a subaddress, compare this subaddress with the subaddress of the own device, and if both subaddresses match, the communication terminal device performs call receiving operation. There is.

Therefore, by inserting a desired sub-address in addition to the called number corresponding to subscriber i5 into a call control message and sending it, the calling party can send a call control message to multiple communication terminal devices connected to one subscriber line 5. It is possible to communicate with a desired terminal device among them, and each communication terminal responds individually if there is no subaddress.

Here, the call connection from the originating terminal to another local bus via another network termination device is performed by the ISDN exchange 4 in the central office.

In other words, when communicating in ISDN, a call setup message containing the telephone number of the called party's private bus is sent from the calling terminal via the network termination device 7 on a 16 kbps control signal channel (D channel). and sends it to the network side.

At the called terminal, each terminal connected to the called terminal's home bus receives this call setup message, which is transmitted from the network via the network termination device 7 on a 16 kbps control signal channel. In the call setup message sent to the network side, each terminal performs a calling operation, and when the calling terminal identifies a terminal that is connected to multiple buses on the called party's home bus and makes a call, A call setup message is sent to the network side by adding a subaddress, which is an identification information element of the terminal, after the telephone number element of the called side's home bus, and each terminal connected to the called side's home bus with multiple buses receives a call setup message from the network. The terminal identification information element in is checked, and if the identification information of the own terminal is found, the calling element is sent to the network side and the calling operation begins.

By the way, in the above case, each terminal can be identified if a call is to be received, but it is impossible for each terminal to identify the cheering party.

Therefore, in the case of an incoming call to a specific called party, it was necessary to have the calling terminal answer once, and then have the person to be called answer the call.

(Problem to be Solved by the Invention) As mentioned above, a communication system using ISDN is configured by connecting a network termination device connected to each subscriber line and a terminal device using an in-home bus. This allows up to eight communication terminal devices to be connected in the case of the basic interface. Then, each of these communication terminal devices is set with a sub-address as terminal identification information, and when an incoming call occurs on the home bus, each communication terminal device uses the sub-address sent from the calling side as its own sub-address. If the two sub-addresses match, the communication terminal device performs a call receiving operation.

Therefore, by inserting a desired subaddress into a call control message and sending it, one calling party can communicate with a desired terminal device among the plurality of communication terminal devices connected to one subscriber line. .

However, the communication terminal device on the called side only emits a ringing tone in response to an incoming call. Therefore, even if the call is to a specific person, someone answers the call and then asks the other party for the individual to be called. Then, I have to do what I said I would pass on to the person in question, which is very bothersome.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a communication terminal device that allows a call to be received by a specific terminal device so that when a user wants to communicate with a specific individual, the call is made to the specific individual.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows.

That is, firstly, in a communication terminal device that is connected to a digital subscriber line premises bus to which a plurality of terminal devices can be connected, and is specified by a set unique sub-address and can receive a call, multiple types of ring tones can be used. a ring tone switching means for selecting one of the predetermined ones; a registration means for setting and registering a sub-address determined for each specific individual and designation information of a ring tone when a call is received to that individual; If there is a sub-address in the sub-address, it is extracted and compared with the information registered in the registration means, and when the sub-address matches, information on setting the ring tone for the individual determined by the sub-address is obtained from the registered information and the ring tone is switched. verification means for switching to the specified ring tone and switching to a normal ring tone when there is no subaddress in the received data, and ring tone switching means when the received data does not have a subaddress or when the subaddresses match; and communication management means for executing ringing with a ring tone switched by.

Also, secondly, multiple terminals! A communication terminal device that is connected to a digital subscriber line in-home bus that can be connected to, and that can receive calls specified by a unique sub-address that is set, has a sub-address determined for each specific individual and when receiving a call to that individual. a registration means for setting and registering call information;
Collation means extracts the sub-address when there is a sub-address in the received data when a call is received, collates it with the information registered in the registration means, and when the sub-addresses match, obtains call information for the individual determined by the sub-address from the registered information; , and notification means for notifying the call information obtained from the verification means (Function) In such a configuration, in the case of the first configuration, the device has the following functions:
It has multiple types of ring tones, and one of these multiple types of ring tones can be selected by command as the ring tone to be sounded when a call arrives. Then, the sub-address specified for each specific individual and the designation information of the ring tone when the call arrives to that individual are registered in the registration means, and when the calling party sends the sub-address including the specific individual's sub-address, the verification means Extracting the sub-address from the received data and collating it with the information registered in the registration means, and when the sub-addresses match, obtaining information for designating a ring tone for the individual determined by the sub-address from the registered information and transmitting the information to the ring tone switching means. Give it a ringtone to switch to that designated ringtone. Note that when there is no subaddress in the received data, control is performed to switch to a normal ringing tone. Then, the call management means executes ringing with the ring tone switched by the ring tone switching means when there is no subaddress in the received data and when the subaddresses match.

In addition, in the second configuration, the sub-address determined for each specific individual and the calling information at the time of incoming calls to that individual are registered in the registration means, and when the calling side sends a message including the sub-address of the specific individual, the verification means When a call is received, a subaddress is extracted from the received data and compared with information registered in the registration means, and when the subaddresses match, call information for the individual determined by the subaddress is obtained from the registered information.

Then, this call information is notified by the notification means.

Therefore, it is possible to immediately know to whom the call is directed by the contents of the call notification notified at the time of the incoming call before answering.

Therefore, according to the present invention, there is provided a communication terminal device that allows a user to easily know to whom the call is received when a call is received on a terminal device connected to a home bus. can.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a telephone that is an embodiment of the present invention.゛In the figure, 21 is a digital subscriber line home bus, 22 is a line interface, 23 is a codec, 24 is a communication circuit, 25 is a handset, 26 is a control unit that controls the entire system, and 27 is a device that generates ringtones, etc. 28 is a hook switch for the handset 25; 29 is a display for displaying characters, etc.; 3;
0 is a key portion having dial keys, designation keys, function keys, etc. The above-mentioned digital subscriber line premises bus 21 includes:
There are two 54 kbps B channels (mainly used as voice communication lines) and a 16 kbps D channel.
Channels (mainly used for network control signal transmission and data communication) are multiplexed.

Further, the line interface 22 separates the B channel signal and the D channel signal and sends them to the codec 23 and the control section 26.
Allocate to. The codec 2-3 converts an audio signal, which is an analog signal, into a digital signal, and converts a digital signal into an audio signal.

The telephone communication circuit section 24 is connected to the codec 23 and drives the handset 25, and supplies the voice signal obtained from the transmitting section of the handset 25 to the codec 23, and receives the signal from the home bus given by the codec 23. is given to the receiver of the handset 25.

Further, the control section 26 plays a central role in controlling the entire device, and includes a communication management means 26a, a called party personal identification information registration means 26b, a called party personal identification information storage means 26C1, and a called party personal identification information collation. Of these, the call management means 26a drives the sounder 27 when a subaddress matches the subaddress collated in the received data at the time of an incoming call, and when there is no subaddress. , hook switch 2
8 is detected, the call is terminated, the call is made, and communication control is performed.

Further, when the called person's personal identification information registration means 26b enters the called person's personal identification information through the key part 30 in the registration mode, it stores it in the personal identification information area of the called person's personal identification information storage means 26c. At the same time, when the tone color information of the ringing tone used for calling the called person is inputted from the key section 30, it has a function of storing this information in the tone color information area of the called person personal identification information storage means 26c.

The called person's personal identification information storage means 26c has a personal identification information area and a tone information area, and the called person's personal identification information registered by the called person's personal identification information registration means 26b and the called person's The tone information of the ringing tone used for calling is associated and stored.

In addition, the called party personal identification information matching means 26d matches the received personal identification information with the personal identification information stored in the called party personal identification information storage means 26c, and if there is matching personal identification information, , has a function of giving an instruction to the ringing tone switching means 26e for switching the tone of the ringing tone, and setting the tone of the sounder 27 to the tone specified for the called party.

Next, we will explain the operation of this device with the above configuration.4 As an embodiment of the present invention, the called party's personal identification number is used as the called party address, that is, the called subaddress that is sent after the called party's telephone number. This will be explained using a telephone that specifies a terminal as an example.

For example, as shown in FIG. 2, it is assumed that eight telephones tip-P8 from terminal #0 to terminal #7 are connected to the home bus 21 of one digital subscriber line.

Assume now that the ring tone setting for the telephones tlP1 to P8 of terminals #0 to #7 has been input and set by operating the key section 30 as shown in FIG.

Here, the called party personal identification number storage means 26 of FIG.
The storage format stored in c is shown. For example, in the case of the called party A with setting NQ 1, the subaddress is ``rlAH'' (1B and H indicate hexadecimal notation), the tone is ``AJ'', and in order to execute the call, the subaddress is This means that the flag is set to "1". In this case, when the called subaddress rlAHJ is received at the time of an incoming call, a ringtone with the tone "A" will sound. Also, the contents of the setting NGO are such that when the called subaddress is not added (no subaddress), the tone will be rC,
In this case, a ringing tone with tone "C" is sounded in the case of an incoming call without a destination address. Similarly, the setting amount 2 is to make a ringtone sound with the tone rB'' for a call from the subaddress rlBH, indicating Mr. 8, and to sound the ringtone with the tone r(, for a call from the subaddress rlcHJ indicating Mr. 0). , Mr. 0, and Mr. 8 indicate that there is no subaddress and the ring tone is tone "C".

Tone "C" is a general tone, and tone "A" and rB.
is a specific tone different from this one. And this tone ``
Regarding timbres ``A'' and ``rB,'' it is possible to specify by a setting flag whether or not to execute calls using the timbres ``A'' and rB.

Focusing on the telephone P2 of terminal #1 in Fig. 2,
The operation will be explained according to the flowchart shown in FIG.

Currently, the sub-address roOH for the bus in my house is roOH.

(However, H is a code indicating hexadecimal notation) Telephone P1 of terminal #10 is set. Mr. A, Mr. B.

Phone P2 of terminal #1, where Mr. 0's calling address rlAH, IBH, and ICHJ are set, and 6 phones from terminal #2 to terminal #7 with no subaddress settings tlIP3 to P8. Suppose that it is connected.

For example, if a caller wants to call Mr. A personally, he adds Mr. A's personal called subaddress rlAH, after the telephone number corresponding to the relevant subscriber line, makes the call, and then the telephone of terminal #1 In P2, when the control unit 26 detects an incoming call (sTl), it next checks whether there is a called subaddress, and if there is a subaddress, it enters Sr1, where the called party personal identification information verification means 26d checks the called party's personal identification information. It is compared with the destination sub-address stored in the identification information storage means 26c as shown in the format shown in FIG. If the destination sub-address rlAHJ is received here, this matches the stored destination sub-address of Mr. A. Therefore, the control section 2
6, the call management means 26a causes the telephone P2 of terminal #1 to return a "call" response to the network as shown in FIG. Controls the ring tone switching means 26e to specify Mr. A's ring tone, that is, the ring tone with the tone color "A," gives a ring tone generation command, and causes the sounder 27 to sound the ring tone with the tone color "A." The ringer is controlled to ring to alert Mr. A that there is an incoming call. Here, the other terminals do not respond because their subaddresses do not match.

By the way, if Mr. A moves near the phone ttlP3 of terminal #2, and if the same settings as above are made on the phone P3 of terminal #2, then the phones ttlP3 of terminal #1 and terminal #2 will be connected to each other.
IP2. Similarly, the P3 can be made to ring with the tone "A" to notify Mr. A of an incoming call. Further, at this time, if the setting of the telephone P2 of the terminal #1 is canceled, only the telephone P3 of the terminal #2 will ring with the tone "A". Therefore, if you select and set the most convenient telephone for Mr. A and specify the tone, the telephone near Mr. A will ring with the tone for calling Mr. A to notify you of an incoming call designated by Mr. A. It is possible to tell Mr. A by distinguishing it from a general call by the difference in tone. When the call is answered, the call becomes possible (Sr1, 5T8), and if there is no response, the call continues until the other party hangs up (Sr1, 5T7), and when the other party hangs up, the control unit 26 stops the ringing sound (Sr9).
).

In addition, if Sr2 cannot receive the called sub-address, all the telephones will answer and ring tone "C" as shown in Figure 5(a), and the incoming call without the called sub-address will be answered. It is possible to notify the user of certain things.

Also, if Mr. A is absent or cannot leave his seat due to a meeting, etc.,
If you add a call rejection label and register it, it will be very convenient to avoid receiving calls when you are busy. At this time, if the caller is provided with an answering function and the caller is informed of the answering function, the system will be more convenient and friendly.

Note that the present invention can be implemented by installing only one terminal in a private bus or by using all eight terminals.

FIG. 6 shows the data format of control information exchanged with the network through the D channel.

As shown in the figure, the message type is stored in octet 4. For example, when a call is received, a call setup message is sent from the network to the terminal.

After octet 5, parameters necessary for each message, that is, a group of information elements are arranged. Since the destination subaddress identifier is placed in octet n and the destination subaddress number is stored in octets n+3 and below, this is read out and compared with the value of the stored subaddress.

Wooden like this! is a communication terminal device that is connected to a digital subscriber line home bus to which multiple terminal devices can be connected and that can receive calls by being specified by a set unique sub-address. Therefore, the control unit includes a ring tone switching means for selecting one of multiple types of ring tones, and a sub-address determined for each specific individual and a ring tone switching means for selecting a specified one from among multiple types of ring tones, and a sub-address determined for each specific individual and a ring tone switching means for selecting a specified one from among multiple types of ring tones. A registration means for registering designation information of a ringing tone, and when a call is received, if there is a sub-address in the received data, it is extracted and compared with the information registered in the registration means, and when the sub-addresses match, it is sent to the individual determined by the sub-address. a verification means for controlling to obtain designation information of a ringing tone from the registered information and supplying it to the ringing tone switching means to switch to the specified ringing tone, and to switch to a normal ringing tone when there is no subaddress in the received data; The apparatus further comprises a call management means for causing ringing with the ringing tone switched by the ringing tone switching means when there is no subaddress in the data and when the subaddresses match.

This device has multiple types of ring tones,
One of these multiple types of ring tones can be selected by command as the ring tone to be played when a call arrives, and the sub-address specified for each specific individual and the ring tone to be used when a call is received to that individual are used. The specified information is registered in the registration means, and when the calling party sends a call including the sub-address of the specific individual, the verification means extracts the sub-address from the received data when the call arrives and collates the information registered in the registration means. When the subaddresses match, information for specifying a ringing tone for the individual determined by that subaddress is obtained from the registered information and is sent to the ringing tone switching means to switch to the specified ringing tone, and when there is no subaddress in the received data, control to switch to normal ringtone,
Then, the call management means controls so that when a call arrives, when there is no sub-address in the received data, or when the sub-addresses match, a ringing is performed using the ringing tone switched by the ringing tone switching means.

Therefore, depending on the type of ringing tone when a call is received, it is possible to immediately know who the call is for, and since it can be set on each terminal, if the individual registers it on the terminal at his/her place of work, it is possible to immediately know who the call is for. This allows calls to be terminated only to terminals near the individual.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings; for example, in the embodiments described above, a conversation machine was explained as an example, but if the terminal is connected to a digital subscriber line home bus, it can be used as a facsimile machine, a facsimile machine, etc. The present invention can also be applied to e-mail terminals and the like if necessary.

In addition, in the above embodiment, an example was shown in which the called person is called by changing the tone of the ringing tone, but instead of the tone, voice data is registered and when a call is received to an individual, voice synthesis is used to send a message to Mr. A. It's a phone call.

The message may be announced by a speaker, or may be displayed by a character display such as an LCD (liquid crystal display).

These can be realized by providing the call management means 26a of the control unit 26 with a control function for this notification.

Furthermore, the personal identification information can also be modified and implemented as desired.

[Effects of the Invention] As explained above, the present invention is capable of receiving an incoming call to which an individual subaddress is added, so that the registered terminal device can know to whom the call is being received. Therefore, it becomes possible to know that an incoming call addressed to a designated individual is addressed to that individual before answering, and a communication terminal device that can dramatically improve usability can be provided.
