Communication terminal system having a function for receiving and transferring selectively a voice message and controlling method therefore}

The present invention relates to a communication terminal system equipped with a voice message selection transmission and reception function and a control method thereof. In particular, after a call is connected to a set phone number, the caller automatically transmits a pre-stored voice message to the receiver to which the call is connected and inputs it from the receiver. The present invention relates to a communication terminal system having a voice message selection transmission / reception function for analyzing a button signal and executing an additional message processing function corresponding thereto.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In addition, in such a network, a telephone system is usually used through an exchange to exchange information converted into an electric signal with a counterpart.

However, such a conventional telephone system is provided with a function of storing a short message service (SMS) recently transmitted from a caller when a user is absent.

Then, referring to the conventional telephone system as described above with reference to Figure 1, the interface unit 72 for interfacing the call signal of the external caller transmitted from the switch system 71 via the PSTN network 70, and this interface unit The ring detect unit 73 detects a ring signal from the call signal input through the 72 and rings a bell (not shown), and the call signal input / output through the interface unit 72 is a predetermined signal processing. A call signal processor 74 for demodulating / amplifying and amplifying, a microcomputer 76 for controlling overall functions of the telephone system 75 including the function of the call signal processor 74, and the call signal processor 74. Memory unit 77 for storing the short messages (SMS) input in the absence of the user according to the function control signal of the microcomputer 76, and the LCD for reproducing the short message signal of the memory unit 77 as a display signal (78).

In addition, a key panel unit 79 for inputting a control command signal or a dialing signal of a user is connected to one end of the microcomputer 76, and a handset 80 is connected to one end of the call circuit unit 74.

On the other hand, referring to the operation of the conventional telephone system as described above, first, when the telephone system 75 is set up, the microcomputer 76 is in the standby state of the function setting signal of the key panel unit 79 or the ring detect unit 73. It is determined whether or not a ring signal is input. At this time, if the ring signal is detected by the ring detect unit 73 and the bell signal is emitted, the microcomputer 76 proceeds to the call standby mode and checks whether the user hooks off the handset 80 for a predetermined time. When the user hooks off in the process, the microcomputer 76 proceeds to the call mode and transmits an incoming call to the counterpart to form a call channel to execute the call function.

That is, the interface unit 72 interfaces the call signal transmitted from the exchange 71 through the PSTN network 70 and inputs it to the call signal processing unit 74. Then, the call signal processor 74 processes the input call signal through a predetermined signal and emits it through the handset 80. When the user makes a call with the handset 80, the call signal is processed through the call signal processing unit 74, and then the external telephone 81 via the interface unit 72 and the PSTN network 70. ) To execute normal call function.

However, in the above process, if the user wants to leave a text message or other call message to a specific use, for example, telemarketing or unspecified recipients, the user inputs a phone number or inputs an SMS message through the key panel unit 79. Then, the microcomputer 76 continuously attempts to connect the call to the input telephone number or transmits the SMS message inputted to the memory unit 77 to the counterpart phone 81 via the exchange 71. Here, if there is a short message from the counterpart phone 81, the exchange 71 processes the predetermined signal and transmits it to the phone 75. Then, the microcomputer 76 of the telephone 75 receives this short message through the interface unit 72 and stores it in the memory unit 77. Then, when the user wants to see the short message stored in the memory unit 77 through the key panel unit 79, the microcomputer 76 displays the desired short message on the LCD 78.

However, in the conventional telephone system as described above, when one caller orally explains the same content to a plurality of recipients, the caller has to execute the same operation each time in succession. Is not provided with the function to check whether the received counterpart is the intended recipient of the transmitted message, because it does not provide appropriate services to the user in terms of providing additional services of the telephone. There was also a problem that the functionality of the considerably degraded.

It provides a control method of a communication terminal system having a voice message selection transmission and reception function consisting of steps.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the apparatus of the present invention includes an interface unit 3 for interfacing a call signal transmitted / received with the exchanger 2 via the PSTN network 1, and a call signal input through the interface unit 3; Ring signal generation unit 4 for detecting a ring signal and ringing a bell (not shown) and call signal input / output through the interface unit 3, for example, a signal signal processing unit for modulating / demodulating and amplifying a call signal. (5), a DTMF decoder (6) for decoding and outputting a response signal of a receiver received through the call signal processing unit (5), and storing and transmitting a telephone number and a voice message of a receiver to be carried on the call signal And a control unit 8 for controlling overall functions of the telephone 7, including a function of analyzing the response signal of the receiver received through the DTMF decoder 6 and transmitting a voice message corresponding thereto. (8) storage control A digital signal processor (DSP) for receiving a caller's telephone number and voice message and a confirmation voice message signal according to the receiver's voice as a caller's voice and converting it into a digital signal or performing a reverse process thereof; Flash memory 10 for storing the telephone number and voice message of the receiver converted by the DSP (9) and the confirmation voice message signal according to the receiver's response.

One end of the control unit 8 is connected to a key panel unit 11 for inputting a user's control command signal or dialing signal, and the other end of the control unit 6 includes a voice message confirmation function. The LCD panel 12 which reproduces the function processing matters as a display signal is connected, and the handset 13 is connected to one end of the call signal processing unit 5. In addition, a speaker 14 and a microphone 15 are connected to one end of the DSP 9.

Next, the control method of the present invention as described above will be described.

In the method of the present invention, as shown in FIG. 3, the process proceeds to the receiver information storage step S2 in the initial state S1 and inputs the telephone numbers of the receivers the caller wants to call, respectively, and corresponds to the entered telephone numbers. Input and store the name of the receiver as the caller's voice. After the receiver information storing step S2, the caller voice message storing step S3 is performed to store the sender's voice message for transmitting the voice message.

That is, the controller 8 of the telephone system 7 firstly inputs the telephone numbers of all the recipients whom the caller wishes to call through the key panel unit 11, and stores them in the flash memory 10, respectively. . Then, the control unit 8 requires the caller to input the name of the receiver corresponding to the telephone number by voice through the LCD panel 12. At this time, when the caller inputs the name of the receiver through the microphone 15, the controller 8 converts the voice signal into a digital signal through the DSP 9 and stores it in the corresponding address of the flash memory 10. . Here, if the caller wants to monitor the process, the control unit 8 emits and monitors the voice signal input by the caller to the speaker 14 through the DSP 9.

In addition, during the process, the controller 8 receives a voice message to be transmitted to each of the receivers , in which the caller inputs a message that he / she wants to convey to each receiver through the microphone 15. Then, the control unit 8 converts the incoming caller's voice message through the DSP 9 and stores it in the flash memory 10.

On the other hand, after the voice message storage step (S3) proceeds to the call connection attempt step (S4) to read the recipient phone number currently stored in the memory and attempts to make a call connection. After the call connection attempt step (S4) The call connection determination step (S5) proceeds to determine whether the call of the currently attempted recipient phone number is connected. At this time, when the call connection determination step (S5), if the call of the telephone number of the currently attempted recipient is not connected to the memory address increase step (S6) to increase the memory address and then to the call connection attempt step (S4) Proceed. However, if it is determined during the call connection determination step (S5) that the call of the telephone number of the currently attempted recipient is connected, the process proceeds to the recipient confirmation message transmission step (S7) and sends a voice message confirming the recipient to the other party.

On the other hand, after the recipient confirmation message transmission step (S7) proceeds to the recipient confirmation determination step (S8) to determine whether the recipient currently connected to the call recipient is the intended recipient. At this time, if the receiver connected to the current call is not the desired receiver as a result of the determination during the receiver confirmation determining step (S8), the memory address increasing step (S6). However, if it is determined during the recipient confirmation determining step (S8) that the caller is the recipient who is currently connected, the caller proceeds to the sender voice message sending step (S9) and the voice message containing the message that the caller wants to deliver to the recipient is received. Send to. Then, after the sender voice message transmission step (S9) to proceed to the receiver response determination step (S10)

It is determined whether a response signal for receiving a voice message is received from the receiver. At this time, if the response signal for receiving the voice message from the receiver is not input even after a predetermined time as a result of the determination in the receiver response determining step (S10), the process proceeds to the previous step (S9) and repeats the loop. However, when the response signal for receiving the voice message from the receiver is input within a predetermined time as a result of the determination in the receiver response determining step (S10), the process proceeds to the receiver response response step (S11) and analyzes the response information input from the receiver. Send the corresponding message.

Here, in the receiver response response step (S11), if it is confirmed that the response signal of the receiver is understood, the receiver further transmits a completion message to the receiver, and then stores the completion time in the memory.

In addition, if it is confirmed in the receiver response response step (S11) that the response signal of the receiver is a request for rehearsal, the voice message retransmission step of retransmitting the voice message is further executed.

If the receiver response signal is confirmed as a signal requesting the sender to leave the receiver message, the receiver response message storing step of receiving and storing the response message is further performed.

On the other hand, during the receiver response response step (11), the caller may perform a direct call execution step of performing a direct call with the receiver when the caller wants to talk with the receiver to which the current call is connected.

In other words, the control unit 8 of the telephone system 7 sequentially reads the phone numbers stored in the flash memory 10 and attempts to continue the call connection through the call signal processing unit 5 and the interface unit 3. At this time, if any one of the phone number attempted to connect the call is connected to the control unit (8) by using the DSP (9) the recipient confirmation message with the corresponding recipient name (XXX) stored in the flash memory (10) 16). For example, "Hello, this message is from XXX. If it is correct, press the phone button 1 or hang up."

In this case, if the other party's receiver hangs up, the controller 8 attempts to call the next address by increasing the address of the flash memory 10 to 1.

However, in the process, if a button signal '1' is input from the opposite receiver, the controller 8 receives it through the DTMF decoder 6 via the interface unit 3. Then, the controller 8 determines that the current recipient is his or her desired recipient, and transmits the sender's voice message stored in the flash memory 10 to the other recipient and waits for the response signal.

Here, the control unit 8 receives and analyzes the response signal transmitted from the receiver through the DTMF decoder 6, and the control unit 8 determines that if the signal of the DTMF decoder 6 is 1; After determining that the sender's voice message is understood and understood, the complete voice message is sent to the other party's receiver, and the completion time is stored in the flash memory 10.

However, when the signal of the DTMF decoder 6 is confirmed to be 2, the control unit 8 determines that the receiver does not understand the voice message of the sender and retransmits the voice message so that the receiver can listen again.

When the signal of the DTMF decoder 6 is determined to be 3, the controller 8 determines that the receiver listens to the sender's voice message and requests to leave the receiver message. 9) After recording through the flash memory 10 to store the reception completion message to the other party.

On the other hand, if the caller monitors during the receiver response response process and wants to make a call with the receiver to which the current call is connected, the control unit 8 proceeds to the call mode and reports the caller's contents through the handset 13. And the transmission through the interface unit 3 to the other party to make a normal call.

Here, although the description of the present invention has been described with reference to the telephone system, the present invention is not limited thereto, and the above functions can be implemented in the same manner as the mobile communication terminal or the WLL terminal.

As described above, the present invention connects a call to a set phone number and then automatically sends a caller's pre-stored voice message to the receiver to which the call is connected, analyzes a button signal input from the receiver, and performs an additional message processing function corresponding thereto. By doing so, since one caller automatically sends a voice message to a plurality of recipients according to the response state, the caller has an advantage of significantly reducing the inconvenience of the caller due to repeated use of the telephone call.

In addition, according to the present invention, since the transmission of the voice message is automatically controlled in both directions according to the response state of the caller receiving the voice message sent by the caller, the functionality of the communication terminal system is also significantly improved.
