Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a communication terminal device used, for example, in I5DN.

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

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. 4, for example. In other words, this system includes a digital circuit switching network 1, a packet switching network 2,
It has an 15DN exchange 4 to which a common line signal network 3, etc. is connected, and a communication terminal device 6 such as a telephone device, facsimile device, voice mail device, etc. in the user's premises is connected to this 15DN exchange t14 via a subscriber line 5. Connected.

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, a basic interface with a transmission rate of 192 bits/second has two B channels of 64 bits/second and 16 bits/second.
The two D channels are time-division multiplexed and these channels are used to transmit data.

By the way, in this type of system, a home line bus is used between the home line terminal device 7 and the terminal device 6 connected to each subscriber line 5, so that a maximum of eight communication terminals can be connected in the case of a basic interface. The device 6 can be connected. Each of these communication terminal devices 6 is configured so that the user can arbitrarily set a sub-address as terminal identification information, so that when an incoming call occurs to the in-home bus, each communication terminal device receives a sub-address from the calling side. The communication terminal device compares the received subaddress with the subaddress of its own device, and if the two subaddresses match, the communication terminal device performs a call receiving operation. Therefore, by inserting a desired subaddress into a call control message and sending it, the calling party can communicate with a desired terminal device among the plurality of communication terminal devices connected to one subscriber 15. .

(Problems to be Solved by the Invention) As mentioned above, the l5DN provides telephone, data, facsimile communications, and various communication processing services in one digital communication network, and the communication system using this l5DN is It has an L5DN switch to which a digital circuit switching network, a packet switching network, a common line signal network, etc. are connected, and communication between telephone equipment, facsimile equipment, voice mail equipment, etc. in the user's premises is made via subscriber lines to this L5DN switch. A terminal device is connected. A plurality of communication channels are time-division multiplexed for each subscriber line, and these communication channels are selectively used to perform desired communication between communication terminal devices.

By the way, this type of system consists of an in-home bus between the in-home line termination equipment connected to each subscriber line and the terminal equipment, and with this basic interface, up to eight communication terminal equipment can be connected. I'm trying to make it possible. 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 calling operation.

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

By the way, the setting of this subaddress is not managed by the network and can be set freely by the user. For this reason, it is difficult to publish a telephone directory that also includes sub-addresses.

Therefore, if a user wants to make a call using a sub-address to specify a terminal, but the user does not know or has forgotten the sub-address of the other party, or if the other party has changed the sub-address. The problem arises that there is no way to check the subaddress.

Therefore, the purpose of this invention is to enable a communication system using 15DN to notify the calling user of the sub-address of the terminal connected to his/her own private bus so that the sub-address can be changed or the caller can notify the sub-address in advance. To provide a communication terminal device which allows communication to be carried out without any trouble even without the user's knowledge.

[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, multiple terminal devices are connected to a home line with the same telephone number, and each terminal device is provided with unique identification information that can be set arbitrarily, so that when a call is made, the calling terminal can identify the called terminal to the called terminal. In a communication system in which information is sent, a called terminal compares the identification information sent from the calling terminal with its own preset identification information, and performs a call receiving operation when both identification information match. , a means for registering identification information of a plurality of terminals connected to the home line, and a list of the registered identification information to the calling party when a call is received from a telephone number to which a preset special number has been added. A communication terminal device is configured by providing means for transmitting the information.

(Function) In such a configuration, it is possible to register in advance the identification information of multiple terminals connected to the above-mentioned home line, and if this registration is completed, the telephone number with the preset special number added can be registered in advance. When a call is received by the number, the sending means sends to the calling party a list of the registered identification information of the plurality of terminals connected in the house. Therefore, in response to this, the calling terminal can learn the subaddress of the terminal with which it wishes to communicate. Therefore, by adding this subaddress and dialing the telephone number, it becomes possible to communicate with the target terminal.

Therefore, according to the present invention, it is possible to provide a communication terminal device that can know the sub-address of a target terminal at the time of communication without knowing the sub-address of the other terminal, and can carry out communication without any hindrance.

(Example) The device of the present invention provides a list of sub-addresses of terminals connected to the own private bus to the calling user by calling a predetermined special number, and thereby the calling user can By adding a special number and dialing the other party's phone number, you can find out the subaddress of the other party's terminal with which you want to communicate.
Therefore, even if the sub-address is changed or the sub-address is not known in advance, the terminal-designated call can be made without any trouble, and is configured as follows.

Hereinafter, one embodiment of the present invention will be described with reference to the mouth surface. FIG. 1 is an embodiment of the present invention, and is a block diagram showing the overall configuration. In this embodiment, a case will be explained in which the basic interface of I5DN is applied.

In FIG. 1, 11 is an l5DN home bus, 12 is a line interface that connects the home bus 11 and this communication terminal device, 13 is a copier, 14 is a speech synthesizer, 15
1 is a control unit, 16 is a display unit, and 17 is a keyboard. The voice synthesizer 14 receives character information (character code data) as input and generates the voice of the character indicated by this character information as an analog signal. Further, the line interface 12 separates B channel information and D channel signals on the home bus 11, respectively. Further, the codec 13 AD converts the audio signal sent from the audio synthesizer 14.
It is converted into a digital signal and provided to the line interface 12.

The display 16 and keyboard 17 are used to register sub-addresses, etc., and display the character code entered on the keyboard 17 on the display 16.
When a registration command is given, the control section 15 takes in this input character code as a subaddress.

The control unit 15 has such a subaddress registration means 15.
It has a subaddress list sending means 15b for subaddresses registered as a.

Among these, the sub-address registration means 15a uses the keyboard 17 and the display 16 to register the sub-addresses of terminals connected to the same local bus. or,
After setting the device to subaddress registration mode, automatic registration may be performed by calling the device from another terminal on the same bus. In l5DN, this is
This is possible because the called party is notified of the caller's number, including the subaddress.

Further, the sub-address list sending means 15b sends a registered sub-address when there is an incoming call with a preset specific service number (special number) added to the communication terminal device.
It has a function of transmitting the list data to the calling side, and then sending the character information of the subaddress list to the speech synthesizer 14, converting it into speech information and sending it out, and then temporarily disconnecting the line. As for the method of sending out the list of subaddresses, in the 15DN, arbitrary user information can be transmitted through the D channel, so this can be used, for example, by adding it to the response message. As mentioned above, the subaddress -
When the list is sent as text information, there is no problem if the calling terminal is equipped with a display and can display D channel user information on that display, but it can be handled if the device is not capable of displaying the information. It also sends audio information. This is done by inputting character information from the control section 15 to the speech synthesis device 14.

FIG. 2 is a flowchart showing the operation. A detailed explanation of the present invention having the above configuration according to this 70 chart is as follows:
First, the calling terminal makes a call to find out the sub-address of the other party, but the telephone number dialed at this time is the main number indicating the other party's home bus, as well as the main number indicating the communication terminal device. Subaddress special code (e.g. "
00'' etc.) (Sr1-1).

When this device receives this, it determines whether or not the subaddress designates itself, and if there is a subaddress that designates itself, it accepts the incoming call.

If the subaddress is different, it will be ignored if no subaddress is added. When an incoming call is accepted, the process goes to 5T1-2, where a pre-registered sub-address list is retrieved. Next, the process goes to 5T1-3, where this sub-address list is stored in the user information area of the response message and sent. The calling terminal receives and displays this (Sr1-2). When the called side sends a response message, a B channel line is established, so the communication terminal device on the called side sends the text information of the sub-address list from the control unit 15 to the speech synthesis device 14, where the text information is 5TI-4>
, the calling terminal receives and reproduces it (Sr1-3>
.

At this point, the line is disconnected. Thereafter, the calling terminal performs a re-call by dialing a desired sub-address from among the displayed sub-addresses (Sr1-4). As for the dialing method here, since it is troublesome to dial the main number again, it is preferable to use a combination of a re-dial key and a sub-address to enable dialing.

FIG. 3 is an example of the structure of a control message sent through the D channel. It consists of a common part into which the call number, message type, etc. are inserted, and an individual part into which other individual information is inserted. The destination sub-address and user information are inserted into the individual section.

In this way, this device has means for registering the sub-addresses of multiple terminals connected to the home bus, and when a call arrives at the device using a special number, the home bus connection registered by the registration means is sent to the calling party. This system consists of a means for sending out a list of sub-addresses of multiple terminals, and when a special code is added and dialed, a list of registered sub-addresses of terminals connected to the destination bus is sent to the calling party. This is so that you can be informed. Therefore,
By connecting one device to each local bus, you can immediately check the sub-address of the target terminal on the other side when necessary without knowing it, and you can communicate with the target terminal by specifying the sub-address. .

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications within the scope without changing the gist thereof. For example, although the above-mentioned device is connected to a home bus as a single unit, it may also be incorporated into a telephone or the like as a module.

[Effects of the Invention] As described in detail above, according to the present invention, even if you do not know the subaddress of the other party's terminal, you can know the subaddress of the target terminal when you want to communicate.

It is possible to provide a communication terminal device that allows communication to be carried out without any hindrance.
