The present invention relates to a method and a device for storing input telephone numbers during a call.

The telephones, which are widely used throughout our living spaces, including general homes and businesses, are the most basic necessities of modern people in the information age. Recently, the telephone functions as a simple telephone equipment that has been conventionally provided for this role. Increasingly, more efficient and convenient functions using microprocessors are being added to telephones.

1 is a block diagram showing an internal configuration of a general telephone with a built-in microprocessor. In the drawing, reference numeral 1 is a trunk line connecting port for connecting an external trunk line, and 2 is applied through this trunk line connecting port 1. A ring signal detecting unit for detecting a ring signal, 3 is a ring generating unit for outputting a ring tone on the basis of the applied ring signal, 4 is impedance matching with the other terminal (hereinafter referred to as a large country) and in the device Interface circuit that performs the interface function of overall communication signals.

Further, reference numeral 5 denotes a handset, 6 denotes a call path controller which interlocks with a hook switch (not shown) driven on / off and controls whether a call is connected, and 7 denotes a call with the interface circuit 4. A network that amplifies the voice signal of the sender applied from the power station and the user's voice signal applied from the handset 5 to the predetermined level as well as performs signal processing for the side tone through the low speed controller 6. (network) circuit.

Reference numeral 8 denotes a voice input unit for allowing a user to directly input voice through the microphone 8a installed on the surface of the phone case without passing through the transmitter 5a of the handset 5, and the voice input unit 8 Microphone 8a for converting a user's voice into an electrical signal, and a microphone interface circuit 8b for interfacing the signal output from the microphone 8a into the device.

On the other hand, reference numeral 9 is a voice output unit for directly outputting the voice signal transmitted from the power station through the speaker without passing through the handset 5b of the handset 5 according to the user's needs, the voice output unit 9 is A speaker amplification interface circuit 9c for interfacing a voice signal applied from the speaker phone driver 15 to be described later, a buffer 9b for amplifying a signal output from the interface circuit 9c, and this buffer 9b. The speaker 9a converts and outputs the signal output from the audio into a predetermined level of audible sound.

Reference numeral 12 is a microprocessor for controlling the operation of the entire apparatus, and 10 is a display unit for informing the user of the current operation state of the telephone under the control of the microprocessor 12, and 11 is a conventional dial telephone such as a speed dial function.

Reference numeral 13 denotes a keypad provided with numeric keys and function keys used for dialing or performing a specific function by the user, and 14 denotes the microprocessor 12 for a predetermined key input entered through the keypad 13. The DTMF generation circuit outputs a DTMF (Dual Tone Multi-Frequency) signal corresponding to the control command.

That is, in the conventional general phone having the above-described configuration, as the user presses a button key provided on the keypad 13 while the user picks up the handset 5, the user dials the corresponding DTMF through the trunk line connection port 1. When a call line is established with the called party by transmitting a signal, a network line 7 is processed by processing the user's voice input through the transmitter 5a or the microphone 8a through the network circuit 7. By transmitting to the other subscriber side through the connection port 1 and outputting the voice signal transmitted from the other subscriber through the receiver 5b or the speaker 9a to provide a call function between the subscribers.

Also, in addition to the normal call function with the above-described communication partner, a phone number storage function for storing a phone number entered in advance, and automatically dialing by a user's specific key selection based on the stored phone number It is possible to provide a speed dial function and a speaker phone function for making a call using a microphone 8a and a speaker 9a without lifting a handset.

Therefore, the existing telephone, after the calling subscriber picks up the handset and confirms the dial tone, dials the called telephone number to send DTMF tones to the switching center, and the switching station translates the received DTMF tones to transmit the ringback tone signal to the called subscriber.

At this time, after the called subscriber picks up the handset and the call path between the incoming and the outgoing call is formed, only a voice signal of mutually generated audible frequency band is converted into an electric signal so that there is no function other than the voice call.

Accordingly, the present invention was created in view of the above circumstances, and during a phone call with the other party, when the other person presses a specific button such as # or * and then presses a phone number, the in-call input recognizes and stores the current phone. It is an object of the present invention to provide a telephone number storage method and apparatus.
