Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional communication terminal device connected to an ISDN user/network interface, and more particularly to a communication terminal device having a message input/output function.

0002

[Prior Art] Conventionally, answering machines that can be connected to existing telephone networks can record several types of messages, and have a function that allows the calling terminal to select and output a specific message from among multiple messages. There are things that I have. In such answering machines, a password corresponding to each message is predetermined, and when the caller makes a call to the answering machine and the answering machine answers, the normal answering message is played back. Let the caller listen. At this time, when the caller enters the predetermined PIN number using the push button, the answering machine checks the entered number with the PIN number pre-registered in the phone and responds accordingly. and starts playing a message that can only be heard by the user who knows the password. After the caller listens to this message, the caller records the message from the caller on the answering machine.

0003

However, in such conventional answering machines, it is not possible to operate the answering machine from a calling terminal before establishing a call. In other words, all communication terminals connected to the existing telephone network are allowed to exchange information only after the call is established, so when using this answering machine, the calling user does not hear the normal response message. This corresponds to the time spent on the phone, the time spent entering the PIN using the push button, the time listening to the individual messages corresponding to the PIN, and the time the answering machine records the messages from the caller. There was a problem in that the user had to pay communication charges for the time, and if the communication distance was long, the user was forced to pay a considerable amount of communication charges.

0004

[Means for Solving the Problems] Accordingly, it is an object of the present invention to provide a system that, when an incoming call from a specific caller arrives, allows each individual caller to receive a call without sending a normal response message or establishing a call. An object of the present invention is to provide a communication terminal device capable of sending a message corresponding to a side user. That is, in order to achieve the above object, the present invention provides ISDN user information.
In a communication terminal device connected to a network interface, an ID registration means for registering a plurality of caller addresses in correspondence with message classification numbers, and a caller ID record for recording a caller address received at the time of incoming call in correspondence with the date and time of incoming call. means, a calling ID verification means for comparing a calling party address received at the time of receiving a call with an address registered by the ID registration means, and a message for determining a number for classifying the message based on the calling party address received at the time of receiving a call. classification number determination means; user message selection means for selecting a message to be sent according to the message classification number determined by the message classification number determination means; automatic disconnection means for automatically disconnecting an incoming call; and automatic disconnection means for automatically disconnecting an incoming call. It is equipped with an automatic transmission means.

[0005]

[Operation] In the present invention, the sender's address, that is, the caller's ID is used as a password, and the user message is used as a message message for the other party's communication terminal device.
When a call arrives at a communication terminal device, the ISD that received the call
I registered in advance in the layer 3 call setup message of N.
When the same caller ID as D is recorded, an individual user message corresponding to the caller's communication terminal device is sent to the ISD.
This is recorded and transmitted in the layer 3 paging message of N, and the calling ID of the calling side communication terminal device is also recorded. As a result, the calling party can listen to user messages corresponding to individual calling users without establishing a call, and
It becomes possible to record the calling ID sent from the calling side.

[0006]

[Example] Integrated Service Digital Communication Network (ISDN:
Intergrated Services Digi
tal Network), the interface that specifies the connection conditions at the boundary point when connecting a terminal and the network is called the user-network interface.
It is defined by CCITT in the 400 series and is generally called the I-interface. Also, I.S.D.
N's services are controlled by layer 3 (network layer) information, which is commonly referred to as "call control" messages. Therefore, in this embodiment, normal messages such as voice messages are expressed as voice messages, and layer 3 messages such as call setup, paging, and response are expressed as "call setup" messages, and "call setup" messages.
"Call" message, "Response" message, etc.
We will use the notation separated by `` and ''.In addition, in this embodiment, the user message is a ``call setup'' message that is included in the ``call setup'' message, which is the layer 3 message mentioned above. This information is sent from the calling terminal to the receiving terminal along with the message, indicating a message from the user, and is information that can be freely set by the user.

[0007] In general, the "call control" messages include the above-mentioned "call setup" message, "calling" message, "response" message, "answer confirmation" message, "disconnect" message, "release" message, and "release" message. There are many other messages in addition to the "Call Setup" message, but at present, the only messages that can record user messages such as the one described above are the "Call Setup" message and the "Call Setup" message.
It is limited to five types of "call control" messages: "call" message, "answer" message, "disconnect" message, and "release" message. The calling party address, or calling ID, is also recorded in the "call setup" message. Such user messages are defined as "inter-user information notification" by CCITT in the I400 series.

In the present invention, the caller ID described above is used as a password, and the user message is used as a message from this communication terminal device to the other party's communication terminal device. Then, when an incoming call arrives at this communication terminal device, if the calling ID that is the same as the ID registered in the communication terminal device is recorded in the received "call setup" message, the communication terminal device sends an individual user message corresponding to the calling communication terminal by recording it in a "call" message, and also records the caller ID of the calling communication terminal. In addition, if the calling ID recorded in the "Call Setup" message does not correspond to any ID registered in this communication terminal, a standard user message is sent to the calling communication terminal. It is transmitted by recording it in a "calling" message, and also records the originating ID of the originating communication terminal device. In addition, if the caller ID is not recorded in the received "Call Setup" message, after establishing the call, similar to a conventional answering machine, a message is sent to the caller's communication terminal device, and then The message sent from the originating communication terminal device to this communication terminal device is received and recorded.

The present invention will be explained in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a communication terminal control device of the present invention. In the figure, 101 is a line interface, 102 is a codec, 10
3 is a route switching unit, 104 is a handset, 105 is a voice storage unit, 106 is a keyboard having dials, function keys, etc., and 110 is a control unit that performs overall control.

[0010]The line interface 101 also has B
The channel signal and the D channel signal are separated and distributed to the codec 102 and the control unit 110. Further, the codec 102 converts an audio signal, which is an analog signal, into a digital signal, and also converts a digital signal into an analog signal. The route switching unit 103 switches the audio route between the codec 102, the handset 104, and the audio storage unit 105. Furthermore, the audio storage unit 105 stores various audio such as message messages recorded by the user in addition to standard message texts prepared in advance.

[0011] The control section 110 also controls the ID registration means 11.
1. Caller ID recording means 112, caller ID verification means 113, message classification number determination means 114, user message selection means 115, user message sending means 116, fixed form message sending means 117, message recording means 118, automatic disconnection means 119, automatic Transmission means 120, mode management means 121
, date and time management means 122.

[0012]The ID registration means 111 registers a plurality of I
This is for registering and recording D in correspondence with the message classification number, and the input is made using the keyboard 106.
This is done by operation. Further, the caller ID recording means 112 is for recording the caller ID together with the date and time of arrival when the caller ID is included in the received "call setting" message. Further, the ID verification means 113 verifies the ID registered by the ID registration means 111 and the ID recorded in the received "call setting" message. Furthermore, the message classification number determining means 114
The message classification number is determined based on the ID recorded in the received "call setup" message. Further, the user message selection means 115 determines a user message based on the message classification number determined by the message classification number determination means 114. Further, the user message sending means 116 sends out the user message selected by the user message selecting means 115.

Further, the fixed message sending means 117 is for sending a fixed message after the call is established if the calling ID is not recorded in the received "call setting" message. The message recording means 118 is for recording the message sent from the other party's communication terminal device after sending the standard message. Further, the automatic cutting means 119
This automatically sends a disconnection signal to the network. Further, the automatic calling means 120 is for automatically sending a "call setup" message to the network. Further, the mode management means 121 is for switching whether the communication terminal device is in the at-home mode or the absentee mode, and this switching is performed by operating the keyboard 106. Further, the date and time management means 122 is for marking the date and time so that when a caller ID and a message are sent from the other party's communication terminal device, they can be recorded together with the date and time of arrival.

Table 1 is an example of an ID registration table showing the correspondence between message classification numbers and IDs registered in the ID registration means 111.

[0015]

[Table 1]

As shown in Table 1, message classification numbers are assigned in order starting from "0" and "1", and there may be any number of the same message classification number. Further, both the message classification number and the ID are input by operating the keyboard 106. It can be seen that the table shown in Table 1 uniquely determines the message classification number that corresponds to the caller ID recorded in the received "call setup" message.

Next, Table 2 shows an example of a calling ID recording table showing the correspondence between the date and time of incoming call and ID recorded in the calling ID recording means 112, and shows the "call setting" of the incoming call.
If an ID is recorded in the message, this ID
is recorded along with the date and time the call was received.

[0018]

[Table 2]

Table 3 is an example of a user message table showing the correspondence between message classification numbers and user messages used when selecting user messages in the user message selection means 115.

[0020]

[Table 3]

Then, using the ID registration table shown in Table 1, a user message is determined based on the message classification number determined by the sender ID verification means 113. If the message classification number cannot be determined by the caller ID verification means 113 (if the caller ID recorded in the received "call setup" message is not recorded in the ID registration table), the caller ID verification means 113 automatically selects the general The user selects "00", which is the message classification number corresponding to the message, and sends the user message.

Table 4 is an example of a message table showing the correspondence between the date and time of incoming call recorded in the message recording means 118 and the voice storage unit address for determining the address in the voice storage unit 105. In other words, if the caller ID is not recorded in the received "call setup" message,
A voice storage unit 1 in which a message is stored in order to determine the message to be sent to the calling terminal device after the call is established.
05 address is determined.

[0023]

[Table 4]

Next, the operation of the control section 110 of the communication terminal device of the present invention when receiving a call will be explained based on the flowchart shown in FIG. When the at-home mode is set by the mode management means 121, the determination in step ST1 when an incoming call arrives is "N", and the telephone functions as a normal telephone (step ST2). If it is set to the away mode, it operates as shown below. That is, if the calling ID is recorded in the received "call setup" message, the determination in step ST3 is "
In this case, the caller ID is recorded by the caller ID recording means 112 (step ST4), and
This incoming call is automatically disconnected without "call setting" (step ST5). Then, the ID registration table registered by the ID registration means 111 is searched, and it is confirmed whether or not there is an ID that is the same as the originating ID recorded in the above-mentioned "call setting" message (step ST6). In step ST6, if the same ID as the calling ID recorded in the "call setup" message exists in the ID registration table, the determination in step ST7 is "Y", and in this case, the message classification number determining means 114, the message classification number is determined (step ST8). Then, based on the message classification number determined in step ST8, a user message is selected by the user message selection means 115 (step ST9), and the user message selected in step ST9 is
The call setting message is recorded and transmitted from this communication terminal device to the other party's communication terminal device (step ST10). Immediately thereafter, automatic disconnection from this communication terminal device is performed (step ST11).

[0025] Also, in step ST6, "call setting" is performed.
The ID is the same as the sender ID recorded in the message.
If it does not exist in the registration table, proceed to step S.
The determination at T7 is "N", and in this case, the message classification number is determined to be "00" (step ST12).
, Subsequently, the user message selection means 115 searches the user message table and selects a user message (step ST13), records the user message selected in step ST13 in a "call setting" message, and transmits it from this communication terminal device. It is transmitted to the other party's communication terminal device (step ST14). And immediately after that,
Automatically disconnect from this communication terminal device (step ST1
5).

[0026] Furthermore, if the calling ID is not recorded in the received "call setup" message, the determination in step ST3 is "N", and in this case, a "response" message is sent to the network ( Step ST16). If a "response confirmation" message is returned from the network in response to this transmission, the determination in step ST17 is "
In this case, the format message sending means 117 selects the field corresponding to the format message in the message table.
A message corresponding to an address whose "Date and time of incoming call" is all "0" is transmitted from the voice storage section 105 to the calling terminal on the other party's side (step ST18). Then, the message recording means 118 records the message from the other party's calling terminal in the message table (step ST19), and then performs call release processing (step ST20).

[0027] As explained above, by recording a user message in a "call setup" message using "inter-user information notification" provided by ISDN, moreover, without establishing a call, It becomes possible to transmit individual messages from the present communication terminal device to the communication terminal device of the other party with a very low communication fee, and it also becomes possible to record the ISDN number of the communication terminal device of the other party.

[0028]

As explained above, the present invention utilizes the calling party's address, that is, the caller's ID as a password, and the user message as a message message for the other party's communication terminal, so that an incoming call is received at the communication terminal. If the ID that is registered in advance is the same as the calling ID of the incoming call,
If D is recorded, an individual user message corresponding to the calling ID is sent and this calling ID is recorded, so the calling party can respond to each calling user without establishing a call. This has the effect that it is possible to listen to user messages sent by the sender, and to record the caller ID sent from the sender, thereby significantly reducing communication costs.
