Abstract

PURPOSE:To always and freely transmit a specific responding message to a specific party from an incoming side without noticing a code number in advance by selecting the responding message corresponding to an identification number transmitted from a outgoing side in the incoming side. CONSTITUTION:An responding message can be recorded by operating a 'registration 1' key and a 'registration2' key of a dial key pad 7 with a user. Then, the collation of a transmitter number involved in a received 'call setting' message and the transmitter number set by a incoming side with the registration 1 is executed, and it is checked that it is specific party or not. As a result, when they are coincident, a 'responding message 1' is reproduced, and when they are not coincident, a 'responding message 2' is reproduced. Thus, when a transmitter is the party registered in advance, the 'responding message 1' is reproduced, and when he is the other arbitrary party, the 'reponding message 2' is reproduced. Thus, without noticing a code number in advance, the specific responding message can always be transmitted to the specific party freely from an incoming side.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a communication system such as I5DN.

(Prior Art) Answering machines that automatically answer calls made when the user is absent have been well known.

An answering machine is very convenient because it automatically sends out a pre-recorded response message from the callee when a call arrives while the caller is away, and can also record the caller's message if necessary.

By the way, when a user receives a call from a specific party while the user is away, there are cases where it is desired to send a specific response message only to that party.

For example, you may want to tell only specific people where you are going. With conventional answering machines, in the above-mentioned cases, a code number is notified to a specific person in advance, and once the incoming call is accepted, the other party inputs the code number, and if the numbers match, the code number is sent to a specific person. A method is used in which a response message is sent, and if the other party does not input the code number, or if the code number does not match even after inputting the code number, a general response message is sent.

However, with the conventional method of using code numbers, the scope of use is extremely limited, such as when the other party is a family member or a specific acquaintance. There was an inconvenience that response messages could not be conveyed. In addition, since a three-frequency signal such as a telephone is used to enter the code number, there are practical problems in that dial pulse telephones cannot input the number code.

(Problem to be solved by the invention) Conventional answering machines that can send a specific message to a specific party use a secret number, so the number of people using the answering machine is limited to family members, specific acquaintances, etc. This is extremely limited, and there is also the inconvenience that a specific response message cannot be conveyed to a party to whom the code number has not been notified in advance. In addition, since a three-frequency signal such as a telephone is used to enter the code number, there are practical problems in that dial pulse telephones cannot input the number code.

The present invention was made in order to solve the inconveniences of the conventional technology in incoming call answering devices, such as the above-mentioned answering machines. The purpose of the present invention is to provide a communication system that can send a specific response message to the other party.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a communication system in which an identification number of a calling party is notified to a called party during connection control, in which a response message for responding to the calling party is recorded. a first recording means in which a response message for responding to the caller and an identification number are recorded in association with each other; A number matching means compares the identification number recorded in the second recording means, and from the matching result by this number matching means, the identification number sent from the calling party matches the identification number recorded in the second recording means. When there is an identification number recorded in the second recording means, a response message corresponding to the identification number recorded in the second recording means is sent to the calling party, and the identification number sent from the calling party is the identification number recorded in the second recording means. The above-mentioned problem is solved by providing an incoming call control means for sending a response message recorded in the first recording means to the calling party when there is no matching number.

(Function) In other words, in the present invention, on the receiving side, a response message is selected according to the identification number sent from the calling side. You can send specific response messages to specific parties.

The communication system in which the identification number of the calling party is notified to the called party is, for example, I5DN (Integrated Service Digital Network). This l5DN is CCITT
(International Telegraph and Telephone Advisory Committee) has been promoting international standardization, and it is expected that it will become widely used for communications such as telephone, data, and facsimile in the future. In this I5DN, by digitally multiplexing the communication information channel (B channel) between terminals and the control information channel (D channel) between terminals and exchanges, various network services that could not be realized with conventional communication networks can be realized. is planned to be provided. For example, simultaneous multi-channel services that allow voice and data communication to be performed simultaneously using multiple B channels, and services that use D channels to notify call charges or caller IDs from exchanges when a call is received. can be given.

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

FIG. 1 is a diagram showing the configuration of an I5DN compatible digital telephone according to an embodiment of the present invention.

In the figure, 1 is data compliant with CCITT Recommendation 1.451 for transmitting and receiving data on a line compliant with CCITT Recommendation 1.430, multiplexing/separating B and D channels, or transmitting call control messages. Line control section (LIC) that performs link control, etc.
Reference numeral 2 denotes a call originating/receiving controller that controls originating/receiving calls using call control messages based on CCI TT Recommendation 1.451.

Further, 3 is a handset, 4 is a codec (C0DEC) for exchanging digital information and analog information, and 5 is a codec (C0DEC) for exchanging digital information and analog information; The audio unit controller 6 is a storage unit that stores digital information input manually from the handset 3 and passed through the codec 4.

Furthermore, in addition to the dial key, 7 also has "Registration 1" and "Registration 2" keys.
” key, etc., 8 is a key controller that exposes the keys input by the dial key bat 7 and converts them into IA5 characters, 9 is a CPU that centrally controls the entire device, and 10 is a handset 3.
This is a switch for switching between transmitting information from the storage unit 6 or information from the storage unit 6.

Next, the incoming call operation of this digital telephone will be explained based on FIGS. 2 and 3. Note that FIG. 2 is an operation state transition diagram, and FIG. 3 is an operation sequence for responding to an incoming call.

In FIG. 2, step 201 is a ready state in which there is no outgoing or incoming call. In this step, in the same way as a normal telephone, in response to an outgoing request (sending a "call setting" message) or notification of an incoming call from the network (receiving a "call setting" message), the system enters the outgoing and incoming operations, respectively. In addition, in this step 201, "Registration 1" provided on the digital telephone
Key The user can record a response message by operating the "Registration 2" key. That is, in "Registration 1" shown in step 202, in order to send a specific response message when receiving a call from a specific caller, after operating the "Registration 1" key, the dial key is operated to enter the caller's number. Please enter your phone number (Step 203)
, memorize this. Next, reply message 1 to this caller, for example, ``I'm out of town right now.
-Please call number xxxxx'' is recorded (step 204), and after the ``absence registration'' key is operated (step 205), the process returns to step 201.

On the other hand, "Registration 2" shown in step 206 is for registering a response message to be sent when receiving a call from a caller other than a specific caller, that is, from any caller, and after operating the "Registration 2" key, the user Then, a response message 2 to an arbitrary party is recorded, for example, a response message to the effect of ``I'm out of town now, if you have a message, please record it'' (step 207). Thereafter, it is set to "absence registration" (step 205), and the process returns to step 201.

Next, the operation when an incoming call is received while the "absent registration" is set and the state of step 201 is set will be explained.

In FIG. 3, when the caller makes a call by dialing the called party on the above-mentioned digital telephone, the call request is sent to the 15DN exchange as a "call setup" message. This "call setting message" includes the telephone number of the other party, that is, the called party's number, and the exchange notifies the called party of the incoming call by transmitting a "call setting" message. This “call setup” message includes l
Caller ID is included as a network service of 5DN special a.

If the receiving party's digital telephone that receives this "call setup" message is set to "absent registration," it will automatically ring for a certain period of time as necessary.
By sending a "Connection" message to the network, a call can be made between the caller and the called party using the B channel. In this case, a response message will be played on the called side to let the caller hear it.

In other words, when there is an incoming call notification (call setup reception) from the network (
Step 20g), first, it is determined whether "absence registration" is being set (step 209), and if it is not, a ring tone is sounded (step 21O) and "absent registration" is set.
When the called party goes off-hook, a "connect" message is sent and normal telephone notification is entered (steps 211 and 212).

On the other hand, if the setting is "absent registration", a "response" message is automatically sent, and the state becomes available for conversation on the B channel (step 213).

At this time, the caller number included in the received "call setup" message is compared with the caller number set by the called party in "Registration 1" (step 214) to check whether it is a specific party. (step 215). As a result, if they match, "Response message 1" is played (step 21B), and if they do not match, "Response message 2" is played. If "Response Message" is for any other party, "Response Message 2" will be played.

In the above embodiment, a case has been described in which one specific caller number is manually input into the storage unit, but it is also possible to input and register a plurality of different caller numbers. Furthermore, the recording means is not particularly limited, such as a tape recorder or an IC memory.

Further, although the above embodiment describes the case where the present invention is applied to a digital telephone, it can also be applied to a facsimile personal computer, etc., it can be made independent as an incoming call answering device, and it can also be implemented on the exchange side. It is also possible to provide the example functionality.

Furthermore, the response message is not limited to voice, but can also be text information or the like depending on the type of terminal.

Furthermore, if the caller numbers do not match or if the caller number is not notified from the network, it is possible to not respond to the incoming call.

Furthermore, in the above embodiment, when registering a specific caller number, the case where all the digits of the caller number are registered is explained, but this also applies even if the lower digits of the caller number are registered. good. In this way, the operation for registering the caller number becomes simple, and there is no problem in practical use.

In addition, in the above embodiment, when comparing the registered caller number and the caller number notified from the network, a complete match of all digits is performed. It may be possible to partially match. In this way, in internal communication within a company, the department or section of the caller can be identified by a certain number of digits, so it is possible to identify not only a certain personal number but also a certain department or section. You can respond to incoming calls.

[Effects of the Invention] As explained above, according to the present invention, the called party can freely send a specific response message to a specific party at any time without notifying the code number or the like in advance.
