Abstract

PURPOSE:To effectively use a limited memory capacity by executing recording in automatic answering only in a recording allowable time stored corresponding to a transmitting source address and a transmitting source subaddress respectively when call-arriving is generated on an automatic answering setting mode and it is from a calling side terminal registered in advance. CONSTITUTION:On selecting an originating side terminal which is a control object, the originating source address and the originating source subaddress of the applying terminal are stored in an IC card 35 in advance corresponding to respective recording allowable time fixed separately. When the generating of call-arriving is detected, a CPU 30 monitors a call setting message transmitted from an exchange and detects the originating source address and the originating source subaddress of the calling side terminal. Then, continuously, the CPU 30 takes in the storing content of the IC card 35 read by an IC card control circuit 34 and collates it with a detected result. Then, when the originating source address and the originating source subaddress are registered, next, recording allowable time information is taken in through the IC card control circuit 34. Thus, the waste of a memory capacity can be suppressed.

Description

[Detailed description of the invention] [Object of the invention] (Industrial application field)
(abbreviated as "N")) is connected to a communication terminal device with an answering machine function.

(Prior Art) In this type of communication terminal device, as an operation related to the answering function, an answering message is recorded in advance on a cassette tape or on an I/O.
When a call arrives in the answering machine setting mode, the stored answering message is immediately sent to the calling terminal.

The voice message returned from the calling terminal in response to the answering message is recorded in the above-mentioned storage means such as the cassette tape or IC memory in the own terminal.

In conventional communication terminal devices of this type, the recording time of the voice message returned from the calling terminal is always fixed at a constant value for any calling terminal. Occasionally there were situations in which a message could only be recorded halfway.

One way to overcome this inconvenience is to lengthen the recording time, but this method requires a huge amount of memory capacity and is therefore limited mainly in terms of cost.

Another method is to increase the recording time while keeping the memory capacity Q unchanged; however, this method inevitably reduces the number of voice messages recorded.

Moreover, in this type of conventional communication terminal device, even if an unimportant voice message is returned, it is always recorded (within the above-mentioned certain period of time), which hinders the effective use of memory capacity ω, resulting in an efficient use of the voice message. The answering machine function was not possible.

(Problem to be Solved by the Invention) In this way, in the conventional communication terminal device described above, if there are a large number of incoming calls in the answering machine setting mode, the answering machine 11 function is activated and used without asking the calling terminal. Since messages were only recorded for a certain period of time, important messages could not be recorded completely, and memory capacity was used only for recording useless messages, making it impossible to realize an efficient answering machine function. There was a point.

The present invention has been made in view of the above-mentioned circumstances, and provides a communication terminal Vt that can reliably record business matters according to the degree of necessity and can realize an efficient answering function by effectively utilizing limited memory capacity. The purpose is to provide

[Structure of the invention]

(Means for Solving the Problems) A communication terminal device of the present invention includes a line connection means for connecting to an integrated digital service line network, and a function for receiving a message by recording on a calling terminal when an incoming call is received in an answering machine setting mode. In a communication terminal device that has an answering machine function that sends an answering machine response message and records a voice message returned from the calling terminal in response to the answering machine response message, A registration means for pre-registering an address and a sender sub-address in correspondence with each permissible recording time, and a sender address and a caller sub-address received from a calling terminal when a call is received in the answering machine setting mode, and the registration means a verification means for verifying the source address and source sub-address recorded in the FL; When the source sub-address is registered by the registration means, the apparatus further comprises a control means for controlling to permit the answering machine recording only for the recording permissible time corresponding to the source address and the source sub-address.

(Function) According to the communication terminal device of the present invention, as shown in the conceptual structure of FIG. It has a storage means such as an IC card 14 in which the source address and the source sub-address are stored in advance in correspondence with the respective recording permissible times, and if there is an incoming call in the answering machine setting mode, the call is received from the exchange in response to the incoming call. The source address and source sub-address of the calling terminal are extracted by the source address verification means 15 and compared with the source address and source sub-address previously stored in the storage means.

As a result of this verification, if a source address and a source subaddress that match the received source address and source subaddress are stored, the calling side terminal responds to the response message sent from the response message sending means 16. When recording the returned message to the message recording means 17, the recording time control means 18 is configured so that the recording time does not exceed the permissible recording time stored in correspondence with the sender address and sender sub-address. We are trying to regulate it by.

In the communication terminal device of the present invention, which regulates the recording time related to the answering function on each terminal registered in advance, a special measure is taken to lengthen the permissible recording time according to the expected demands of the business. By taking the following measures, it is possible to effectively utilize the limited memory capacity Q, and of course, for unregistered partner terminals, recording is not permitted at all, or recording is permitted only for a very short period of time. It is possible to minimize waste of capacity.

The switch circuit 38 is switched by inputting an instruction for audio reproduction by the operator of this device, and by selectively connecting the voice synthesis circuit 36,
0 (stored in a recording IC memory 42, which will be described later), can be played back.

The switch circuit 39 selectively connects either the telephone call circuit 25 or the voice analysis circuit 41 to the voice transmission path with the other party's terminal.

The voice analysis circuit 41 A/D converts the voice signal of the calling side terminal received through the line in the answering machine setting mode, and stores it in the recording IC memory 42.

In a SON to which a communication terminal device having such a configuration is connected, a call setting message as shown in FIG. 3 is generally used.

In FIG. 3, (a) shows a call setup message sent from the optical calling terminal, and (b) shows a call setup message sent from another exchange to the called terminal in response to this call. .

As is clear from FIG. 3, in the 15DN, the optical calling side terminal uses the message common area 432 source subaddress 442
Destination address 45. When the call setup message [FIG. 6(a)] consisting of the destination subaddress 46 is sent, the exchange □ adds the originating address 47 of the optical calling side terminal immediately after the message common part 43 of the call setup message [FIG. (b)] is transmitted to the called terminal.

Furthermore, the detailed structure of this call setting message has a form as shown in FIG.

That is, in FIG. 4, (a) corresponds to the call setting message shown in FIG. 3(a), and (b) corresponds to the source address 47 in the call setting message shown in FIG. 3(b). are doing.

As is clear from this Figure 4, the source address 4
7 is an optical source address information element 47a and an information element length 47b.
After the number identification 47c, the sender address is entered one digit at a time up to m digits.

In this embodiment, the caller address 47 and caller sub-address 44 are used to variably control the recording time at each caller's end when the answering function is activated in response to an incoming call in the answering setting mode. It is something.

In order to realize such control, the communication terminal device of the present invention includes:
After selecting the originating terminal to be controlled, the originating address and originating sub-address of the terminal are stored in advance in the IC card 35 in correspondence with the permissible recording time determined for each terminal.

This IC card 35 can be attached and detached as necessary.
When installed, the C
The registration status can always be recognized and recognized by the PU 30.

An advantage of using a portable recording medium such as the IC card 35 is that the controlled T11 terminal and the corresponding recording permissible time can be easily set or changed by simply attaching and detaching the card. can give.

It goes without saying that other storage means may be used in consideration of operational convenience, cost, etc.

Based on these setting conditions, the operation of the communication terminal device of the present invention will be described in detail below with reference to the flowchart shown in FIG.

First, the main sending end device is normally maintained in a state where it monitors the occurrence of issuing and incoming calls (steps 5a and 5b).

In this monitoring state, when the occurrence of a call is detected in step 5a, for example, the CPLI 30 performs a prescribed call processing based on the instruction from the instruction input unit 31 accompanying the operator's call operation (step 5c). ).

Separately, when the occurrence of an incoming call is detected in step 5b with the arrival of a call setup message from the exchange, C
The PLI 30 determines whether or not its own terminal is in the answering machine setting mode (step 5d).

If it is determined in this judgment that the mode is not the answering machine setting mode, the CPLJ 30 performs normal incoming call processing (step 5e).

On the other hand, although it is determined in the above judgment that the terminal is in the answering machine setting mode, the CPU 30 sends an answering machine response message to the calling terminal to the effect that the operator of the own terminal is absent and that if there is any business, it will be accepted by a recorded shout. (Step 5f).

This answering message can be recorded using a recording IC, for example.
CPLJ the fixed message stored in the memory 42
30, the voice synthesis circuit 36 converts the voice signal into a voice signal and sends it from the transmission circuit 29 to the calling terminal via the home bus 21.Another method is to send text information corresponding to this fixed message. be.

The calling terminal that received this answering machine response message,
If there is a message to be conveyed to the called terminal through answering machine recording, the operator uses the handset 26 to transmit this message to the called terminal at the same time as a normal call.

During this time, the CPU 30 sends an i! The call setting message sent from ki is monitored, and the source address and source subaddress of the calling terminal at this time are detected (step 5a).

Subsequently, the CPU 30 reads the memory content of the IC card 35 read by the IC card control circuit 34, and compares this memory content with the detection result in step 5g to determine what was sent from the exchange during the above-mentioned incoming call. It is determined whether a source address and a source subaddress that match are registered (step 5h).

As a result of this verification, if a source address and source subaddress that match the source address and source subaddress of the calling terminal are registered, then the CP
U30 takes in recording permissible time information stored in IC card 35 corresponding to these source addresses and source subaddresses through IC card control circuit 34 (step 5i).

Thereafter, when the CPU 30 records the voice message returned from the calling terminal in response to the answering message to the recording IC memory 42 through the voice analysis circuit 41, the CPU 30 recognizes the recording time recognized by the processing in step 51 and allows the recording. Regulate this by setting an upper limit on the time (step 5)
j).

Thereafter, when the recording of the voice message from the calling terminal is completed by reaching the recording permissible time, the CPU
Step 3-0 performs a prescribed disconnection process to disconnect the line (step 5k>).

On the other hand, as a result of the verification in step 5h, if the source address and source sub-address that match the source address and source sub-address of the calling terminal are not registered, that is, the call was received from an unspecified person. In case, C
The PU 30 performs a normal answering service without the above-mentioned restriction on the permissible recording time (step 51).

As a specific example of this normal answering machine response, for example, when an incoming call from an unspecified person is detected, a message is sent to the calling terminal to inform the operator that the message cannot be recorded, and the calling terminal There is a method of performing the disconnection process (step 5k) without recording any voice messages from the user.

In addition, recording may be enabled only for a very short fixed period of time, for example, about 10 seconds, and the quick cutting process may be performed.

Such control in a normal answering service regulates the recording time of a voice message from an unspecified person and contributes to suppressing the waste of memory 8 of the recording 1c memory 42.

In addition, in this embodiment, when a call is received in the answering machine setting mode, when the calling terminal is identified and the recording time of the voice message is variably controlled by the calling terminal, the message is sent from the exchange in response to the above-mentioned incoming call. This is done by referring to both the source address and the source subaddress that are sent, but the same effect can be expected by checking each separately, such as only the source address or only the source subaddress. It is possible.

〔Effect of the invention〕

As explained above, according to the communication terminal device of the present invention, when there is an incoming call in the answering machine setting mode, the originating address and originating sub-address of the calling terminal that receives the incoming call from the exchange is registered in advance. If the calling terminal is registered in advance, the calling terminal is recognized depending on whether the calling terminal is registered in advance or not, and if the calling terminal is registered in advance, only the recording permissible time stored in correspondence with the above calling source address and calling source sub-address is recorded. Since answering machine recording is performed, incoming calls from unregistered terminals are restricted, thereby reducing wastage of memory capacity Q, and even registered terminals can only be used for the time set for each. This system has an excellent advantage in that it is possible to disable recording during an answering session, and it is possible to realize an extremely efficient answering function that makes effective use of the limited memory capacity Φ.
