Abstract

PURPOSE: A method for automatically storing a telephone number of a mobile communication system is provided to implement a DTMF detect module in a cellular phone, and to detect a number when other party presses a number key in a busy state, thereby automatically storing the number in a memory. CONSTITUTION: The first caller dials a predetermined telephone number by using a mobile phone, and presses a send key(S1). A speech path is formed with the other party through a base station by using the dialed telephone number. A telephone decides whether a set burst DTMF message including the predetermined telephone number is received through a forward traffic channel from the other party while calling the other party(S4). If so, the telephone decides whether a detected DTMF tone corresponds to a number button(S5). If so, the telephone stores the detected DTMF tone in a DRAM(S7). If the DTMF tone is not the number button, the telephone decides whether the tone corresponds to a specific character(S6). If so, the telephone stores the telephone number in a flash memory(S8).

Description

How to save phone number of mobile communication system automatically {MOBILE PHONE}

The present invention relates to a method for automatically saving a telephone number of a mobile communication system, and in particular, receives a telephone number of a counterpart during a telephone call in the form of a DTMF (Dual Tone Multi Frequency) signal, and receives a DTMF tone from a communication terminal. The present invention relates to a method for detecting whether the DTMF tone is received and automatically storing the same in a memory by including a module for detecting.

A user who makes a phone call using a mobile phone may have a situation in which it is difficult to memorize a phone number of the other party, compared to a user who uses a general telephone.

For example, a user who makes a phone call using a mobile phone is very inconvenient and dangerous to take note of the phone number that the other party calls while driving. In addition, the user of the mobile phone must also remember the phone number informed by the other party until the end of the call also occurs a problem that can not concentrate on the phone call with the other party.

Accordingly, the present invention has been made to solve the problems of the prior art, the mobile telephone is equipped with a DTMF module when the other party presses the key (Key) during the call detects the number and stores in the memory using a method To save the other party's phone number automatically.

That is, a DTMF tone discrimination step of determining whether DTMF tones are detected during the counterpart video call,

In the DTMF tone determination step, when DTMF tones are detected, a numeric tone determination step of determining whether they are 0-9 tones,

Storing the number in the DRAM when the number tone is determined in the number tone determination step;

A special character determination step of determining whether the number tone is '*' or '#' tone when the number tone is not determined;

In the case of the special character determination step, if the special character is stored in the flash memory, the phone number of the counterpart may be automatically stored.

11: second caller 12: first caller

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

1 is a diagram showing a schematic situation of a communication method according to the present invention. During communication, a first caller 12 inputs a number button corresponding to a phone number and a special character indicating a phone number input to the second caller 11. To). The terminal of the second caller 11 determines whether the DTMF tones are received during communication, and stores the DTMF tones in the memory (Dram) and corresponds to a special character indicating that the input of the telephone number is completed. When the # 'button is input, the number stored in the memory is stored in the FLASH memory.

2 is a flowchart illustrating a method for automatically storing a telephone number of a mobile communication system according to the present invention.

Referring to Fig. 2, first, a first caller dials a predetermined telephone number using a mobile telephone and presses a transmission key (S1) to form a call path 26 with a call counterpart via a base station. . One telephone determines whether a set-burst DTMT message including a predetermined telephone number has been received from the other party during the call with the other party through the forward traffic channel (S4). When the DTMF tone is detected, the step of determining whether the corresponding DTMF tone corresponds to the number button (S5) and the number button is stored in the DRAM (S7). In the case, the telephone number stored in the memory (DRAM) is stored in the FLASH MEMORY (S8).

As described above, the present invention receives the counterpart's telephone number through a send burst DTMF message and stores it in a memory during a telephone call, so that it can be retrieved later. Therefore, it is possible to eliminate the inconvenience of not taking notes in a situation that can not take notes, such as driving, and can increase the use efficiency of the mobile phone.
