Abstract

The present invention discloses a phone number transmitting and receiving and automatic storage method in phone talking, which includes the following steps: 1) a transmitting terminal judges whether the phone number is selected for search in the phone talking, if it is true, the selected phone number will be inputted; 2) the transmitting terminal transforms the phone number to DTMF information and load it to DTMF pulse signal for transmitting; 3) a switchboard receives the DTMF pulse signal, reads out the DTMF information and transforms it to phone number, and sets the record type to phone number function and transmits it to a receive terminal after storing the phone number in express information message; 4) the receive terminal receives the express information message and judges whether the record type is set to phone number function, if it is true, reads out the phone number stored in the CHARi field and stores it to phone number book. The invention can reduce the inconvenience that the receiver should remember the phone number to be received one by one or the phone number should be input by key region.

Example Embodiment

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0011] figure 1 It is a system structure diagram of the method for sending, receiving and automatically storing telephone numbers in a telephone call of the present invention. As shown in the figure, it includes: a sending terminal 11, which loads the telephone number pressed during the telephone conversation or the telephone number retrieved in the telephone directory into the DTMF pulse signal for transmission; the switch 13, which receives the above-mentioned DTMF pulse Signal, store the telephone number information in the express information message, set the record type to the telephone number function and transmit it to the receiving terminal; the receiving terminal 14, which receives the above-mentioned express information message, judges whether the record type is the telephone number function, and if it is true value, the phone number information stored in the CHARi field is read and stored in the phone directory.
[0012] The sending terminal 11 loads the telephone number pressed during the telephone conversation into the DTMF pulse signal and transmits it. In addition, the telephone number retrieved in the telephone directory is loaded into the DTMF pulse signal and transmitted. The DTMF pulse signal conveys the DTMF tone and number corresponding to the pressed key.
[0013] The structure of the DTMF pulse signal is shown in Table 1:
[0014] field
[0015] In the above fields, the number of DTMF tones, the DTMF start (ON) interval, the end (OFF) interval, and the DTMF tone sequence are sequentially indicated.
[0016] The exchange 13 receives the above-mentioned DTMF pulse signal, loads the DTMF information into the express information message and transmits it to the receiving terminal 14, sets the record type of the express information message to the keypad function, converts the DTMF information into a telephone number and stores it in the CHARi field.
[0017] The structure of the express information message is shown in Table 2:
[0018] Table 2
[0019] Call Types for Express Information Messages
[0020] Information record type
[0021] type - specific field
[0022] Set the record type of the express information message to the phone number function, load the phone number information in the CHARi field, and store the phone number length in the length field.
[0023] The receiving terminal 14 receives the above-mentioned express information message, determines whether the record type is a telephone number function, and if it is a true value, reads the telephone number information stored in the CHARi field and temporarily stores it in the telephone directory.
[0024] The following describes an embodiment in which a user transmits a phone number to the other party during a phone call with the other party.
[0025] When the user has a phone number to transfer, select the phone directory search or select the keypad function in the menu. Select Phone Book Search to select the desired phone number, or press a key in the selected keypad function to enter a phone number.
[0026] The sending terminal converts the telephone number input by the user during the telephone conversation into DTMF information corresponding to the number, and loads it into the DTMF pulse signal for transmission. The DTMF tones and the number corresponding to the telephone number input by the user are stored in the DTMF pulse signal.
[0027] The DTMF pulse signal is transmitted to the switch via the base station, and the switch reads the DTMF information loaded in the received DTMF pulse signal and converts it into a phone number. The converted phone number is loaded in an express information message and transmitted to the receiving terminal.
[0028] The switch sets the record type of the express information message to the telephone number function, and stores the telephone number in the CHARi field.
[0029] After receiving the express information message, the receiving terminal determines whether the record type is set to the telephone number function, and if it is a true value, reads the telephone number stored in the CHARi field.
[0030] Also, the read telephone number is temporarily stored in the telephone directory. After the phone call ends, the other party confirms the phone number temporarily stored in the phone directory, and can also enter other additional information.
