The present invention relates to utilize in the communication process dual-tone multifrequency signaling receiving system to show the method for telephone number, specifically, relating to callee in both sides' communication process receives the calling party with Dual Tone Multifrequency and pushes the telephone number of keyboard input or a kind of method of other number.This patent application proposes according to korean patent application 32144/1995, also this patent application is included usefulness for reference here.

In general telephone system, when the calling party imported telephone number with the keypad of telephone set, the telephone set of receiving words side can not write down or show this telephone number in communication process.General telephone set only adopts such method, and promptly under user's " standby " state without its telephone set, telephone number is got off by the memory means record of EEPROM (electrically-erasable programmable read only memory) that receives words side and so on after keying in the device input.Having under the situation of answering machine, when telephone set was in " conversation " state, telephone number just was recorded to tape or Digital Signal Processing part.During on-hook,, receive the words people and can record telephone number down, or after hearing recording, telephone number is write on the note board with the method for above-mentioned recording phone number if be in " standby " state.Therefore, the result is, because telephone number does not have stored record to go in the memory when receiving the words people in conversation, receives the words people and must write or remember telephone number.

In a word, in the prior art, receive the words people in communication process, must remember any telephone number at once the time, must write or learn by heart the telephone number of offering when the calling party converses.After the on-hook, receive the words people and can utilize the memory dialing function of telephone set to write down the telephone number.Also have inconvenient like this place in addition, promptly the calling party can not receive the words people certainly and whether correctly receive telephone number.

Therefore, the purpose of this invention is to provide receive receive that in communication process the calling party imports in words side any number afterwards with its a kind of method of noting.

Another object of the present invention provides a kind of method that any number of receiving that in communication process the calling party imports in words side displays it afterwards of receiving.

For reaching above-mentioned purpose of the present invention, provided by the invention have when receiving telephone system from the dual-tone multifrequency signaling receiving system of the dual-tone multifrequency signaling signal of exchange line and shows that in communication process the method for telephone number comprises the following steps: in communication process employing telephone number receiving mode exchange line is received the dual-tone multifrequency signaling receiving system; After described Connection Step, detect the corresponding dual-tone multifrequency signaling signal of telephone number of calling party's input, and show detected signal.

Consult following detailed description in conjunction with the accompanying drawings and can more fully understand the present invention and subsidiary many advantages thereof.In the accompanying drawing, same numbering is represented same or similar parts, wherein:

Fig. 1 is the block diagram of telephone set of the present invention;

Fig. 2 is the control flow chart that receives and show telephone number in the communication process.

Describe a most preferred embodiment of the present invention in detail referring to accompanying drawing below.

As shown in fig. 1, CPU (central processing unit) CPU110 controls the total course of work of telephone set, controls the record and the procedure for displaying of telephone number in the communication process in addition.It is telephone line is connected with speaking circuit device 114 or disconnects that hook switch relay 112 has individual switch hook to be subjected to the control of CPU110, the effect of relay 112.Speaking circuit device 114 is subjected to the control of CPU110, and distribution and transmission are by voice signal and other tone signal of telephone line input.DTMF generating means 116 is connected with speaking circuit device 114 and CPU (central processing unit) CPU110, will convert dtmf signal to from the digital data signal of CPU110, and output it to speaking circuit device 114.DTMF receiving system 120 will be converted to numerical data and provide digital signal to CPU110 from the dtmf signal of speaking circuit device 114.DTMF receiving system 120 receives calling party's telephone number as the dtmf signal input in both sides' communication process, and dtmf signal is offered CPU110.Ringtone detection device 122 is connected with telephone line and CPU110, detects the bell signal of importing by telephone line and provides it to CPU110.The telephone number that data that display unit 124 demonstration CPU110 provide and calling party import in both sides' communication process.Storage device 126 is stored the telephone number of importing in menu that the various functions of phone are provided and the communication process under the control of CPU110.Storage device 126 adopts EEPROM so that need not the just telephone number of energy memory storage of electric energy.Keying in a plurality of keys of device 128 has one to be multiple-frequency signal receiver MFR key, in order to MFR being connected to exchange line or disconnecting with exchange line so that in communication process receiving dialed number.Key in device 128 button data that button operation produces is offered CPU110.Key in device 128 also according to telephone number being offered CPU110 by the numerical key of self importing.
