Abstract

PURPOSE:To execute calling with proper volume corresponding to each user by determining each individual terminating subaddress, setting up and registering the subaddress and a terminating personal calling volume and ringing a calling tone by the set/registered volume. CONSTITUTION:A terminating subaddress is previously determined in each specific person, the subaddress and the volume specification information of a terminating calling tone to the person are registered in a registering means 26b, and when data including the terminating subaddress of a specific person are transmitted from the calling side, a collating means 26d extracts the terminating subaddress in the received data at the time of termination and collates the extracted subaddress with the information registered in the means 26b. When both the terminating subaddresses coincide with each other, the volume specification information of the calling tone to the person determined by the subaddress is obtained from the registered information and applied to a calling tone volume switching means 26e to switch the volume to the specified level.

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 an in-home bus of an integrated service digital network 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.
integrated 5erv1ces dlglta
lnetwork).

This I5DN provides telephone, data, facsimile communication, and various communication processing services in one digital communication network, and a communication system using this I5DN is configured as shown in FIG. 9, for example. That is, this system has an 15DN switch 4 to which a digital circuit switching network 1, a packet switching network 2, a common line signaling network 3, etc. are connected, and a T line (up line) and an R (down line) ) A communication terminal device 6 such as a telephone device, a facsimile device, a voice mail device, etc. in the user's home is connected via a home bus of a digital communication network subscriber line 5 consisting of -. A plurality of communication channels are time-division multiplexed for each subscriber line 5, and these communication channels are selectively used to perform desired communication between communication terminal devices. For example, in a basic interface with a transmission rate of 192 bits/second, two B channels of 64 bits/second and one D channel of 16 bits/second are time-division multiplexed, and these channels are used to transmit data, etc. Perform transmission.

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 (ISDN The subaddress is searched from the call setup message sent from the exchange (exchange side), and if a subaddress is found, this subaddress is compared with the subaddress of the own device, and if the two subaddresses match, the communication terminal device performs call receiving operation. .

Therefore, by inserting a desired sub-address in addition to the called number corresponding to the subscriber line 5 into a call control message and sending it, the calling side can send a call control message to a plurality of communication terminals connected to one subscriber line 5. It is possible to communicate with a desired terminal device among the devices, 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 I5DN switch 4 of the central office.

That is, when communicating in the 15DN, the calling side terminal sends a call setup message containing the telephone number of the called side's private bus on the 16 kbps control signal channel (D channel) via the network termination device 7. , and send it to the network side. Then, at the called side terminal, each terminal connected to the called side 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. Then, each terminal performs the calling operation. In addition, when the calling side terminal identifies a terminal that is connected to multiple buses on the called side's premises bus and attempts to make a call,
In the call setting message sent to the network side, a subaddress, which is an identification information element of the terminal, may be added after the called party's home bus telephone number element and then sent to the network side. As a result, each of the multiple terminals connected to the called party's home bus checks the terminal identification information element in the call setup message received from the network, and if it has the identification information of its own terminal, calls the network side. Sends the element and enters the call operation. Like this l5
With DN, multiple terminals can be connected to one in-home bus, and it is also possible to distinguish between these terminals and receive calls.

On the other hand, in general, in offices, etc., a single telephone is often shared by multiple users, and in such cases, there are users who are seated very close to the telephone and users who are seated quite far away. . Although a low-volume ringtone may be used to notify nearby users of an incoming call, a high-volume ringtone is required to notify a user in a far seat of an incoming call.

Conventional telephones were unable to differentiate between these users and the ring volume was the same for all users. In addition, in most cases, these volumes are set by users sitting near the phone, and users who are near the phone may choose to set the ringer at a low volume because setting it at a high volume would be noisy. In many cases, it is set to the volume.

For this reason, when a user near the phone is seated at his or her own seat, he or she can receive an incoming call from a co-user located at a seat further away from the phone and have the user answer the call before continuing. Sometimes this is not possible, and the ringing tone is so low that it is difficult for users who are far away to hear the ringing tone, making it difficult for users to answer incoming calls.

(Problem to be Solved by the Invention) As described above, a communication system using 15DN is configured by connecting a network termination device and a terminal device connected to each subscriber line by a home bus, As a result, in the case of the basic interface, a maximum of eight communication terminal devices can be connected. 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, the calling party can communicate with a desired terminal device among the plurality of communication terminal devices connected to one subscriber line by inserting a desired subaddress into a call control message and sending it. Can be done.

However, when the called phone receives a call to its own phone,
The ringtone only sounded at a preset volume, making it impossible to distinguish between users.

Therefore, if the ring tone is set at a low volume, the system is configured to ring at a low volume even for users who are far away, so there is a problem that the user has difficulty hearing the ring tone. , ISDN's advanced identification capabilities have not contributed to any improvement in this respect.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a communication terminal device that is capable of emitting a ring tone at a volume appropriate for the user by using the destination address received at the time of an incoming call. .

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. In other words, it is connected to the digital network subscriber line in-house bus, and it is possible to set and register a destination sub-address as desired.
In the call terminal device that enables an incoming call specified by a call including the called sub-address, a volume switching means for selecting a ringing volume at the time of an incoming call, and a predetermined called sub-address and its identification. a registration means for setting and registering information specifying a ringing volume when a call is received; When there is a sub-address to be called, the information for specifying the ringing volume for the specific person corresponding to the matching sub-address is obtained from the registered information and is given to the volume switching means, and when there is no called sub-address in the received data, the ringing volume is set to the normal ringing volume. and a communication management means that, when a call arrives, sounds a ringing tone at the volume selected by the volume switching means to notify the user of the incoming call.

(Function) In such a configuration, a called sub-address is determined in advance for each specific individual, this and information for specifying the volume of the ringtone when a call is received to that individual is registered in the registration means, and the calling party can send a call to the specific individual. When a call is sent including the called sub-address, the verification means extracts the called sub-address from the received data at the time of an incoming call, collates it with the information registered in the registration means, and when the called sub-address matches, calls the individual determined by that sub-address. Sound volume designation information is obtained from the registered information, and is applied to the ring tone volume switching means to switch to the designated volume. Furthermore, when there is no subaddress in the received data, the volume is controlled to be switched to the normal volume. Then, the call management means sounds the ring tone at the normal volume if the received data does not contain a sub-address or does not match, and when the called sub-address matches, it sounds the ring tone at the volume switched by the ring tone volume switching means. let

Therefore, it is now possible to make the ringer sound at a volume that is appropriate for the user, such as ringing at a high volume when receiving a call to a person who is far away from the communication terminal device, and at a low volume when receiving a call from a person who is nearby. You will be able to make calls based on the situation, such as by making a sound.

(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 private bus, 22
2 is a line interface, 23 is a codec, 24 is a telephone communication circuit section, 25 is a node set, 26 is a control section that controls the entire system, 27 is a sounder that generates a ring tone, etc., 2
8 is a hook switch of the handset 25, 29 is a display for displaying characters, etc., 30 is a dial key or designated key,
This is a part of the key that has function keys etc. The above-mentioned digital subscriber line home bus 21 has two 64 kbps B channels (mainly used as a voice communication line) and a 16 kbps D channel (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 connects the codec 23 and the control unit 2 to each other.
Allocate to 6. The codec 23 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 communication management means 26a, called party sub-address registration means 26b, called party sub-address storage means 26c,
It has a caller sub-address verification means 26d and a ring tone volume switching means 26e. Among these, communication management means 26
When a subaddress matches the received data by checking the destination subaddress, or when there is no subaddress, a operates the sounder 27, and also performs call termination, call origination, and communication control based on the detection of the hook switch 28.

Further, when the called party sub-address registration means 26b enters the registration mode and inputs the called party sub-address through the key part 30, it stores this in the sub-address area of the called party sub-address storage means 26c, and also inputs the called party sub-address from the key part 30. When the volume information of the ringing tone used for calling the called party is input, this information is stored in the called party sub-address storage means 26c.
It has a function to store in the volume information area of.

The called party sub-address storage means 26c has a sub-address area and a volume information area, and includes the called party sub-address registered by the called party sub-address registration means 26b and the volume of the ringing tone used for calling the called party. Correlate and memorize information.

Further, the called party sub-address verification means 26d verifies the received called party sub-address with the sub-address stored in the called party sub-address storage means 26c, and if there is a matching sub-address, the ringing tone changes the volume of the ringing tone. The sounder 2
7 to a volume specified for the called party.

Next, the operation of this device having the above configuration will be explained. As an example of the present invention, the volume of the ring tone is "loud".

A telephone set that can be set to three levels: "medium" and "small" will be described.

For example, as shown in FIG. 2, it is assumed that eight telephones P1 to P8 with terminal numbers #0 to #7 are connected to a home bus 21 of one digital subscriber line. Now, phone P1
It is assumed that the volume for each called party at the time of incoming call is stored in the called party sub-address storage means 26c in the control section 26 in the format shown in FIG. Incidentally, this setting is performed by operating the key part 30.

Here, in FIG. 3, for example, in the case of the called party A with setting Nα1, the subaddress is rlAHJ (however, H is 16
This means that the volume is set to "loud" and the setting flag is set to "1" in order to execute the call. In this case, when receiving the called subaddress rlAHJ at the time of an incoming call, a ringing tone with a "loud" volume is sounded.

In addition, the contents of settings No. and O mean that the volume is set to "low" when the called subaddress is not added. In this case, the volume is set to "low" for an incoming call without the called subaddress. A ringtone sounds. Similarly, setting No.
, 2, for a call from the sub-address rlBHJ indicating Mr. 8, a ring tone is sounded at a medium volume, and for a call from a sub-address rlcHJ indicating Mr. 0, a ring tone is sounded at a volume of ``low''. , Mr. 0 and Mr. 8 have no sub-address and the ring tone is f1 "low".

The characteristic operation of the present invention will be explained below using the flowchart shown in FIG.

For example, if the caller wants to make a call to Mr. A, the caller adds Mr. A's personal subaddress rlAHJ after the telephone number corresponding to the subscriber line and makes the call. In the receiving telephone P1, when the control unit 26 detects an incoming call (ST1
), the presence or absence of the called party sub-address is checked, and if there is a sub-address, the process goes to ST3, where the called party sub-address verification means 26d stores the called party sub-address rlAHJ in the called party sub-address storage means 26c as shown in the format of FIG. If received, this matches Mr. A's memorized subaddress.

Therefore, the control section 26 uses its call management means 26a to "call" the telephone P1 of terminal #1 to the network as shown in FIG. 5(b).
It returns the following response.

Further, the control unit 26 controls the ring tone volume switching means 26e to specify the ring tone of Mr. A stored as shown in FIG. 3, that is, the ring tone with the volume "high",
A ringing tone generation command is given, and the sounder 27 is controlled to emit a ringing tone at a volume r high, thereby notifying Mr. A of the incoming call (ST5). At this point, the other terminals do not respond because their subaddresses do not match.

Then, if you answer the call, you will be able to make a call (ST6,
5T8) If there is no response, keep calling until the other party hangs up (
ST6.5T7) If the other party hangs up, the control unit 26 stops the ringing tone (ST9).

Furthermore, if the destination sub-address cannot be received in ST2, all the telephones respond individually and emit a ring tone at a "low" volume (STIO), as shown in FIG. 5(a).

Therefore, it is possible to make a ringtone sound at a volume appropriate for the user.

In addition, in this embodiment, if there is no subaddress, the volume is
Although we have shown an example where the volume is set to "low", this is due to the settings, so by changing the settings, it can be seen that the volume is implemented in exactly the same way whether it is set to "high" or "medium".

Further, as shown in FIG. 7, as an example of the configuration of the volume switching circuit system, the output of the oscillator 83 is connected to a series resistor 84a.

84b to the sounder 27, and series resistors 84a and 84b are connected to relays 81a and 81.
The series circuits b are connected in parallel, and the slide switch 8
The series circuits of 2 and relay 81c are connected in parallel, and one of the switching contacts of slide switch 82 is connected to the connection point of resistors 84a and 84b and the connection point of relays 81a and 81b, and the selection of relays 81a and 81b or the relay By selecting 81c and slide switch 82, the output of oscillator 83 is output without attenuation, and through one of resistors 84a or 84b.
Alternatively, by using a circuit configured to select one of the routes through the resistors 84a and 84b, the relays 81a to 81c1 are controlled by the ring tone volume switching means 26e.
The configuration is such that the on/off of the oscillator 83 is controlled. As a result, normally, that is, when there is no called party sub-address, the volume is set by the key switch such as the slide switch 82, and when the called party sub-address is received, the volume is set by the relay 81a, 81b.
, 81c can be activated in combination to switch the amount of attenuation and control the sound volume to a desired set volume. In this case, the volume is as follows.

81 a: OFF, 81 b: OPF, 8
1 c: ON Volume set with slide switch 8 81a: OFF, 81b: OFF, 81c
:OFP :Volume "low" 81a :OPF, 81b :ON, 81c :O
FF: Volume “medium” 81 a: ON, 81 b: ON, 81
c: OFF: Volume is "high" Here, 84a and 34b are resistors for adjusting the volume.

Moreover, as shown in FIG. 8, the same effect can be obtained by using an element such as a slide volume 85 or the like which can continuously vary the resistance steplessly in place of the slide switch 82.

In addition, in the embodiment, the settable volume is set to "loud".

Although there are three levels, ``medium'' and ``small,'' it is possible to implement the process in exactly the same way even if it is made variable in two or four or more levels.

Further, 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, 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. When the destination subaddress identifier is placed in octet n, the destination subaddress number is stored in octet n+3 and below, so this is read out and compared with the value of the stored subaddress.

[Effects of the Invention] As explained above, the present invention determines a called sub-address for each individual, sets and registers the personal ringing volume at the time of receiving a call, and registers the called sub-address to be received at the time of an incoming call and the preset user's sub-address. The communication terminal device is configured to match the sub-address and, when a match is made, sound a ringtone at the volume registered for the setting, so that a communication terminal device that sounds a ringtone at an appropriate volume according to the user is provided. can.

Furthermore, according to the present invention, the volume of the ringtone can be changed between a user who is far from the communication terminal device and a user who is close to the communication terminal device. You can also get the effect that it becomes very convenient.
