Description

 How to send and receive phone numbers and automatically save them during a phone call {METHOD FOR LOADING PHONE NUMBER WHEN LINE IS BUSY}

1 is a diagram illustrating a system configuration for a method for transmitting and receiving a telephone number and automatically storing a telephone call according to the present invention.

The present invention relates to a method for transmitting and receiving a telephone number and automatically storing a telephone number during a telephone call. Particularly, the telephone number transmitted and received during a telephone call can be automatically received and stored in a telephone directory by a receiving terminal. The automatic storage method.

In general, when a user wants to make a phone call with the other party, when the user hears a ring tone after pressing the other party's phone number, the user starts talking with the other party. The telephone number is composed of unique DTMF tones that are assigned differently for each number and is transmitted to the exchange and used to transmit the ring tone to the other terminal.

The conventional mobile communication terminal encodes and delivers a user's voice during a phone call and receives and decodes and outputs the encoded voice of the other party. When the user presses a key during a phone call, a DTMF tone is generated, which may interrupt the call.

If a user has a phone number to inform the other party during a phone call, the user orally forwards it and the other party remembers the phone number or stores it in the phone book. It can be delivered using a short message rather than verbally.

However, in the prior art as described above, the other party has to remember or memorize the received phone number and store it in the phone book, so if you receive the wrong number when you receive the phone number is a problem that must be communicated with the user again have.

Accordingly, the present invention has been made in view of the above problems, and transmits a telephone number by a combination of keys pressed during a telephone call in a calling terminal or a telephone number selected by searching a phone book to a receiving terminal in the receiving terminal. An object of the present invention is to provide a method for transmitting and receiving a telephone number and automatically storing a telephone number during a telephone call so that the telephone number received from the calling terminal can be automatically stored in the telephone book.

The present invention for achieving the above object, the step of receiving a telephone number selected by the phone book search during the telephone call operation in the calling terminal; Converting the inputted telephone number into DTMF information in the calling terminal and transmitting the DTMF burst message to a switch; Reading, converting, and converting DTMF information stored in the DTMF burst message into a telephone number in a flash information message and setting a telephone number function in a record type to a receiving terminal; And receiving the flash information message at the receiving terminal and reading the telephone number stored in the CHARi field and storing it in the telephone directory if the telephone number function is set as a record type.

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

1 is a diagram illustrating a system configuration for a method for transmitting and receiving a telephone number and automatically storing a telephone number during a telephone call of the present invention. As shown in FIG. A calling terminal 11; An exchanger (13) for receiving the DTMF burst message and storing telephone number information in a flash information message and setting the telephone number function as a record type and transmitting it to a receiving terminal; Receiving the flash information message, it is determined whether the record type is a telephone number function, and if true, it comprises a receiving terminal 14 which reads the telephone number information stored in the CHARi field and stores it in the telephone directory.

The calling terminal 11 transmits the telephone number pressed during the phone call in a DTMF burst message. In addition, the phone number retrieved from the phone book is transmitted in a DTMF burst message. The DTMF Burst Message conveys the DTMF tone and number corresponding to the pressed key.

The structure of a DTMF burst message is as follows:

TABLE 1

field NUM_DIGITS 8 DTMF_ON_LENGTH 3 DTMF_OFF_LENGTH 3 DIGITi 4 CON_REF_INCL One CON_REF 0 or 8

In this field, DTMF tones, DTMF on intervals, off intervals, and DTMF tone sequences are indicated in order.

The exchange 13 receives the DTMF burst message and transmits the DTMF information to the receiving terminal 14 in the flash information message. The flash information message sets the keypad function to record type, converts DTMF information into a telephone number, and stores it in the CHARi field.

The structure of the flash information message is as follows.

TABLE 2

Call Types for Flash Information Messages

Information record type of keypad function

Info record type Record type Message type Paging Channel Forward traffic channel Phone number function 00000011 flash No Yes

Type-specific field of keypad function

Type-specific fields Length (bits) CHARi 8

Set the phone number function to the record type of the flash information message, store the phone number information in the CHARi field, and store the phone number length in the length field.

The receiving terminal 14 receives the flash information message, determines whether the record type is a telephone number function, and if true, reads the telephone number information stored in the CHARi field and temporarily stores it in the telephone directory.

Hereinafter, an embodiment in which a user transfers a phone number to be communicated to a counterpart during a phone call with the counterpart is described.

The user selects a phonebook search from the menu or selects a keypad function if there is a phone number to be forwarded. Select Search Phonebook to select the desired phone number or enter the phone number by pressing the keys on the selected keypad function.

The calling terminal converts the telephone number input by the user during the telephone call into DTMF information corresponding to the number and transmits the DTMF burst message. The DTMF burst message stores DTMF tones and numbers corresponding to the telephone number entered by the user.

The DTMF burst message is transmitted to the exchange via the base station, and the exchange reads the DTMF information contained in the received DTMF burst message and converts it into a telephone number. The converted phone number is transmitted to the receiving terminal in a flash information message.

The exchange sets the phone number function to the record type of the flash information message and stores the phone number in the CHARi field.

When the receiving terminal receives the flash information message, the receiving terminal determines whether the telephone number function is set as the record type, and if true, reads the telephone number stored in the CHARi field.

Then, the read phone number is temporarily stored in the phone book. The other party checks the temporarily stored phone number in the phone book after completing the phone call and enters the remaining additional information.

 As described in detail above, the present invention saves the phone number to be transferred during the phone call to the phone book temporarily stored in the phone book to reduce the inconvenience of having to manually remember the phone number to be delivered or directly input by the keypad Giving effect.
