Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a communication terminal device with a so-called answering function that is connected and operated to an 15DN network (integrated digital service network). .

(Prior Art) Conventionally, communication terminal devices are known that have a function of automatically answering an incoming call and sending a predetermined message back to the calling party when an operator is absent. In this type of communication terminal device, an answering machine response message is stored in advance on a cassette tape, an IC memory, etc., an answering machine response message is stored in the cassette tape player IC memory, and when there is an incoming call in the answering machine setting mode, This stored answering message is immediately sent to the calling terminal.

Then, the voice message returned from the calling terminal in response to this answering message is stored (recorded) in a storage means such as a cassette tape or IC memory installed in the own terminal.
I try to do that.

In conventional communication terminal devices of this type, the recording time of a voice message returned from a calling terminal is always fixed at a constant value, even for the calling terminal.

For this reason, there has been a problem in that even though the voice message is extremely important, it can only be recorded halfway.

In order to solve this problem, there is a method of lengthening the recording time, but this method requires a huge amount of memory capacity and has the drawback of increasing the size of the device and increasing costs.

Another possibility is to increase the recording time while keeping the memory capacity the same, but this method would inevitably result in an extremely small number of recorded voice messages.

Moreover, with this type of conventional communication terminal device, even if an unimportant voice message is returned, recording is always performed for the specified period of time, which hinders the effective use of memory capacity, resulting in an efficient answering function. There was a problem that I couldn't do it.

(Problem to be Solved by the Invention) As described above, in the conventional communication terminal device, when a voice message is returned, it is necessary to record for a certain period of time. There were problems in that a large amount of the storage area was used, and important messages were not recorded, which hindered the effective use of the memory capacity and, as a result, made it impossible to realize an efficient answering machine function.

The present invention has been made in order to eliminate the problems of the conventional communication terminal device described above, and its purpose is to provide a communication terminal device that can realize an efficient answering function by effectively utilizing storage capacity. It is to be.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes: a line connection unit connected to a network that sends a called address and a called subaddress regarding a called side terminal; and a message that sends a predetermined message stored in advance. sending means; storage means for storing a message sent from a calling terminal; and controlling said message sending means to send said predetermined message when an incoming call is detected when answering mode is set; and a control means for controlling the storage time of the message in the storage means to perform the storage based on the incoming call sub-address.

(Function) According to the above configuration, if the calling side does not send the terminating subaddress for the terminating terminal as a predetermined terminating subaddress, the memory time is set to zero or extremely short, or the predetermined terminating subaddress is sent. If you receive a call, you can memorize it for a predetermined period of time, or store it in a variety of ways.You can also make the answering function more efficient by letting important parties know the predetermined incoming sub-address. can be realized.

IC memory 4
2) can occur. 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 tC memory 42.

In the 15DN network, a communication terminal device having such a configuration is
It controls outgoing and incoming calls by sending and receiving call setting messages as shown in the figure. Figure 3(a) shows a call setup message sent from the calling terminal, and Figure 3(b) shows the call setup message sent from the calling terminal.
The call setup message sent from the exchange to the called terminal in response to the call setup message shown in FIG. The call setup message (FIG. 3(a)) sent from the calling terminal is composed of a message common part 43, a source subaddress 44, a called address 45, and a called subaddress 46. Upon receiving a)), the exchange adds the source address 47 immediately after the message common section 43 to create a call setting message (FIG. 3(b)) and sends it to the called terminal. FIG. 4 shows the detailed structure of the call setting message. Here, the source address 47 includes a source address information element 47a, an information element length 47b1, a number identification 47c, and then the source address is separately m
It has a structure that includes up to digits.

In this embodiment, the incoming call sub-address 46, the calling source address 4γ, and the calling sub-address 44 are used, and when the answering function is activated in response to an incoming call in the answering mode (setting), the recording time is set for each calling terminal. It is designed to be variably controlled. Therefore, in order to select the calling side terminal that should be allowed to record the calling side's message in the IC card 35 for a predetermined recording time, the calling side address, the calling side subaddress, and the called subaddress sent from the 15DN network are used. are stored in association with each separate recording allowable time. The IC card 35 can be attached to and removed from the device as needed, and when it is attached to the device,
The above data can be read by the CPU 30 via the IC card control circuit 34. In addition, this IC card 3
The advantage of using a portable storage medium such as No. 5 is that when multiple communication terminal devices of the same type are connected to the home bus 21, the communication terminal device to which the answering service should be answered can be changed by a simple operation of attaching and detaching the medium. The main feature is that it is possible to easily change the settings of the calling terminal that should allow message recording and the recording time. Of course, other means may also be used, such as manually setting and changing the keys depending on the system.

In the communication terminal device configured as described above, the CPU 30 executes the operation in the answering mode using a program of a flowchart as shown in FIG.

When this communication terminal device is powered on and the CPU 30 starts operating, it determines whether to make a call (5a), whether to set the answering machine (proxy answering) mode (5C), and whether calls are rarely received (5d). Starts monitoring operation. Here, if it is detected that a call is being made (off-footer, etc.), the call processing (5b
), the call processing is controlled by a program (not shown), and when an incoming call is detected (arrival of a given call address), the process advances to normal call processing (5g), where a program (not shown) controls the call processing. Controls call processing.

On the other hand, for example, when a predetermined key of the instruction input section 31 is operated,
When the setting input for the answering machine (proxy response) mode is made, the process branches to YES from step 5C, and a message indicating that the answering machine (proxy response) mode is set is displayed on the display 32 (5e). next,
The CPU 30 detects whether there is an incoming call (5f), and if no incoming call is detected, the process returns to step 5a, and if the incoming call is detected, the process returns to step 5D.
The incoming subaddress sent from the N network (45 in Figure 4)
) is detected (5g), and whether it matches the incoming sub-address stored in the IC card 35 (already registered).
5h). Here, if there is a mismatch, normal incoming call processing is performed (51). Therefore, although a ringing tone is generated, the user is not answered because the user is away. If they match in step 5h, the source address and source sub-address sent from the 15DN network are detected (5j), and whether they match the source address and source sub-address stored in the IC card 35 (registered address detected). (5k). If there is a mismatch here, the CPt 130 controls the voice synthesis circuit 36 to send out an answering proxy response - that is, a predetermined message - and controls the switch circuit 37 to send the codec 24 and frame assembly circuit 28. , the audio signal is transmitted through the path of the transmitting circuit 29 (51), and the response message from the other party is not recorded, and the process proceeds to step 5p.Meanwhile, step 5
When the CPU 30 detects that the call has been made, the CPU 30 controls the speech synthesis circuit 36 to send a message as a reply on behalf of the answering machine (5m). Prompt for input. Then, the corresponding recording time information is read out from the corresponding IC card 35 (5n), and upon completion of sending the message for answering by proxy, the switch circuit 39 is controlled to analyze the voice signal sent from the calling terminal. A route is created to reach the circuit 41, and the operation of the voice analysis circuit 41 is controlled for the recording time read above to store the voice signal in the recording IC memory 5o). After this time has passed, the line is disconnected. (5p) and ends. Thus, according to this embodiment, it is possible to allocate the required amount of recording time in response to the incoming call sub-address, the sender address, and the sender sub-address sent from the sender terminal, and to ensure that important messages are not sent. Messages that may be received from the calling terminal can be accurately stored, and memory capacity can be used efficiently.

In this embodiment, whether or not to record is solely determined based on the incoming call sub-address, but the storage time may be changed based on the incoming call sub-address. Furthermore, if it is inconvenient not to record at all, the recording may be limited to about 10 seconds, for example.

[Effects of the Invention] As explained above, according to the present invention, since the storage time of messages sent from the calling terminal is controlled using the incoming call address sent from the network, By teaching a predetermined incoming call sub-address to the recipient, the necessary storage time can be secured according to each recipient, and the storage capacity of the storage means can be effectively utilized to realize an efficient answering function.
