A part 4, a call circuit part 5 for connecting a call path when an off-hook signal of the handset 7 is applied from the hook detecting part 4, and an additional function part 6 for storing a separate service function And the key to the other party's phone number Keypad unit 11 for inputting a signal, memory unit 10 for storing data for the other party's telephone number, and dial signal generation unit 8 for transmitting DTMF signals to the other party's telephone number which is automatically dialed and sent And a display unit 12 for displaying general operations according to the use of the telephone, and a control unit 9 for controlling the overall operation of the telephone.

In the conventional telephone configured as described above, when the user off-hooks the handset 7 in a state in which a required operating power is applied to each circuit unit from the power supply unit 3, the hook detection unit 4 detects this and the call circuit unit ( The call path of 5) is connected to the interface unit 1. Subsequently, when a key signal for automatic dialing to a specific counterpart is input by operating a predetermined key of the keypad unit 11, the controller 9 detects the input key signal and selects a key signal for the selected counterpart stored in the memory unit 10. Access your phone number. Thereafter, the control unit 9 controls the dial signal generation unit 8 to transmit a DTMF signal for the telephone number accessed from the memory unit 10 and apply it to the call circuit unit 5 side. The call circuit unit 5 amplifies the DTMF signal applied to the tip line and the ring end of the trunk line connected to the interface unit 1 through the connected communication path.

In addition, a bell signal that can be audible by the user according to the incoming signal of a predetermined cycle is applied to the bell generating unit 2 through the interface unit 1 from the tip end and ring end of the trunk line. It generates a beep and applies the state of application of the incoming signal to the control unit 9 side. When the handset 7 is off-hook according to the ring tone, the hook detection unit 4 detects this and connects the call 5 from the conference call. When the call circuit unit 5 is connected, the voice signal of the other party applied through the interface unit 1 from the tip and ring ends of the trunk line is transmitted through the call path of the connected call circuit unit 5. To the side. At this time, the call circuit unit 5 amplifies and outputs the applied side voice signal to a predetermined level, and the display unit 12 displays general operation information according to the use of the phone, that is, the called party's telephone number. The additional function unit 6 performs an automatic answering function, a holding sound transmission function, and the like, for the incoming signal applied in the absence of the telephone user.

As described above, the conventional telephone is equipped with only a simple memory function for the other party's telephone number, and thus fails to check the information about the stored telephone number or the meaning of the number when calling a specific counterpart. There was a problem.

In addition, a phone equipped with a separate display function also displays only the called party's phone number. Therefore, when a user wants to recognize information about a called phone number in detail, it is necessary to check a separate record or rely on the memory of the user who stored the phone number. There was this.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and its object is to provide a convenient way for a user to access a call after confirming related information about the other party's phone number stored in a memory means and general information about a user by a voice transmission in a communication system.

Process of doing; When the handset means is off-hook within a predetermined time as a result of the determination, and there is a call connection request, the speed dialing method includes automatically transmitting the read telephone number as a DTMF signal.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram of a single-axis dialing apparatus in which a single-axis dialing method according to the present invention is implemented. FIG. 3 is a flowchart for explaining a single-axis dialing method according to the present invention.

As can be seen in Figure 2 the present invention, the interface unit 101, the hook switch 102, the handset 103, the bell generating unit 104, the microphone 105, the speaker 106, recording memory unit 107, recording and playback section 108, voice signal processing section 109, dial signal generating section 110, additional function section 111, control section 112, keypad section 113, memory section 114 And a display unit 115.

The interface unit 101 is connected to a tip end and a ring end of the trunk line to connect voice and data transmission and reception between the user and the trunk line. The hook switch 102 detects whether the handset 103 is off-hook and applies it to the signal control unit 112 corresponding thereto and at the same time to the interface unit 101 to control the connection to the call.

The bell generating unit 104 is connected to the interface unit 101 and generates a bell signal so that a user can recognize when an incoming signal is applied from a tip end and a ring end of the trunk line. The microphone 105 is connected to the voice signal processor 109 and inputs information about a voice signal of a user who makes a call while the handset 103 is on hook and information on a counterpart phone number to be stored. The speaker 106 outputs an incoming call tone according to the bell signal applied from the bell generating unit 104 and outputs a received voice signal applied from the voice signal processing unit 109 when the call is made while the handset 103 is placed on hook. And transmits information on the other party's telephone number stored in the recording memory unit 107. The control unit 112 controls the overall operation of the phone. The recording memory unit 107 stores general information such as personal information and position of the other party's telephone number input to the microphone 105 as a digital PCM (Pulse Code Modulation) signal. The recording and reproducing unit 108 converts the analog voice information of the other party's telephone number applied from the microphone 105 through the voice signal processing unit 109 into a digital signal, and stores the digital PCM signal stored in the recording memory unit 107. Is converted into an analog signal. The additional function unit 111 performs a separate service function, that is, a service function such as an automatic response or a pending sound transmission. The keypad unit 113 includes ten keys (0 to 9) for dialing and a predetermined function key to store and dial a counterpart phone number (including a speed dial). The memory unit 114 stores the counterpart phone number input from the keypad unit 113. The display unit 115 displays the general operation according to the use of the phone and the counterpart phone number that is automatically dialed. The dial signal generator 110 generates a DTMF (Dual Tone Multi Frequency) signal according to the transmission of the telephone number input from the keypad 113 and the telephone number stored in the memory 114.

Referring to the single-axis dialing method according to the present invention with reference to the single-axis dialing device configured as described above with reference to the flow chart of FIG.

When the control unit 112 detects the input of the key signal for the voice reduction dial function from the keypad unit 113, it is determined whether the input key signal is the input mode of the telephone number (step 1) and then the telephone number input. In the mode, the telephone number input from the keypad 113 is stored in the memory 114 (step 2), and then a key signal for voice recording of information on the telephone number input from the keypad 113 is checked. It judges (step 3). If no key signal is input for voice recording, the storage of the input telephone number is completed (step 7). If it is determined that the key signal for voice recording is input, the recording and playback unit 108 is controlled to control the recording from the speaker 106. The applied audio analog signal is converted into a digital PCM signal and stored in the voice memory unit 107 (step 4). Thereafter, it is determined whether or not the key signal for confirming whether or not the voice signal is stored is input to the voice memory unit 107 (step 5). Input of the audio information is completed (step 7), and the program returns to the main program mode.

If the other party's phone number for the voice short dial and the voice information thereof are stored, the control unit 112 operates if the key signal determined in step 1 is not a key signal for the phone number input mode but a speed dial key signal using voice. The mode is set to the transmission mode of the telephone number stored in the memory unit 114 (step 11). If the telephone number is set to the transmission mode, it is determined whether or not the signal applied from the hook switch 102 is on-hook (step 12). If it is determined that the on-hook signal is applied, the controller 112 accesses the selected telephone number from the memory unit 114 (step 13), and then inputs a key signal for reproducing the recorded voice from the keypad unit 113. It judges (step 14). When inputting a key signal for reproducing the recorded voice, general information about the telephone number accessed from the memory unit 114 is accessed from the recording memory unit 107, and then the digital PCM is transmitted through the recording and reproducing unit 108. The signal is converted into an analog signal to reproduce the voice recorded through the speaker 106 (step 15). Thereafter, the controller 112 continuously detects whether or not the recorded voice is completed (step 16) and determines whether the handset 103 applied from the hook switch 102 is an off-hook signal when the playback is completed. (Step 17). When the handset 103 is detected as an off-hook signal, the control unit 112 transmits the telephone number accessed from the memory unit 114 through the dial signal generation unit 110 as a DTMF signal and applies it to the interface unit 101. . The interface 101 outputs an applied DTMF signal to a tip end and a ring end of the trunk line through the connected communication path (step 18). When the transmission of the telephone number is completed, the control unit 112 clears the data of the accessed counterpart telephone number and waits for connection of the call (step 19).

If the handset 103 is judged to be in an off-hook state in the determination of step 12, the control unit 112 accesses data on the telephone number stored in the memory unit 114 (step 23), and then the dial signal generation unit 110 is performed. Is transmitted to the trunk line side as a DTMF signal (step 24), the data accessed from the memory unit 114 is cleared, and the connection of the call is awaited (step 25). If it is determined in step 14 that the input of the key signal for reproducing the recorded voice is not detected, the data read out from the memory unit 114 is cleared (step 21) and then enters the standby state (step 22). If the handset 103 is detected to be on-hook in the determination of step 15, it is determined whether the predetermined time set for off-hook has elapsed (step 20), and the other party read from the memory unit 114 if the predetermined time set has elapsed. The data for the telephone number is cleared (step 21) and the standby state is entered (step 22).

As described above, in the present invention, when automatically transmitting a phone number stored in a memory unit by using a speed dial function, the call connection is made by automatically checking the information on the phone number to be transmitted before the stored phone number is transmitted. To provide convenience.

It also provides convenient use for visually impaired situations or blind people.
