Abstract

PURPOSE: A method for receiving number-related information in a cellular phone is provided to exactly display the number-related information to store the information in a memory while a telephone line of the cellular phone is busy, and to optionally retrieve the number-related information to make a user use or delete the information, so that the user can easily receive various number information messages without a pencil or other recorded media. CONSTITUTION: A user starts a call with other terminal according to an incoming signal in a call stand-by state. If the user has to receive number-related information from other terminal, the user sets up a self terminal mode into a number information receiving mode. A system controller delivers a mode setup stand-by signal to the other terminal. The system controller detects number-related information received from an antenna, and sequentially displays the detected number-related information on a screen. If a signal for completing transmissions relating to the number-related information is received, while displaying the information on the screen, the system controller automatically stores the information in a memory. If the call is not completed, the system controller automatically converts the self terminal mode into a calling mode to continuously make the call with the other terminal.

First, in the call waiting state, the wireless call processor 10 amplifies and demodulates an RF signal received by the antenna 1, converts it into a digital signal, and outputs it to the system controller 80. The system controller 80 transmits a wireless call. Receiving a destination address among the digital signals output through the processing unit 10, and compares and determines with a unique number (ID number) and outputs a bell signal indicating that the call has been received (S1).

When the user initiates a call according to the incoming ring signal and talks with the other party through the voice input / output unit 20, and is verbally notified that there is numerical information to be transmitted from the other party during the call, the user can enter a specific key of the wireless terminal. In addition, the system controller 80 generates a signal corresponding to the numeric information receiving key and sets the baseband processing unit 16 and the modulator 18 of the wireless call processing unit 10 by selecting. And a signal indicating that the numeric information reception mode is standby through the amplifying unit 19 is notified to the counterpart (S2).

Thereafter, the system controller 80 receives data corresponding to the DTMF (Dual Tone Multiple Frequency) pulses output through the radio call processor 10 and the DTMF detector 30 to determine whether transmission of the numeric information is started from the counterpart. After the numeric information has been transmitted, the numerical information is sequentially controlled to display the numerical information on the screen of the display unit 40 (S3).

That is, the number of key switches pressed by the other party through the key matrix of the wireless or wired terminal is sequentially transmitted and displayed on the screen of the user's wireless terminal.

Subsequently, after sequentially displaying the numeric information transmitted by the counterpart on the screen of the display unit 40, the system controller 80 determines whether the numeric information completion signal for completing the transmission of the numeric information is transmitted from the counterpart (S4). .

Here, since the terminal of the other party transmitting the numeric information may be a wired terminal or a wireless terminal, a key switch for sharing the numeric information may be shared between the wired terminal and the wireless terminal, for example, a ＃ or ＊ key switch. It is desirable to set and program with.

In addition, as a result of the determination, when a signal corresponding to the numeric information transmission completion signal is received from the counterpart, the system controller 80 automatically receives the received numeric information, that is, the numeric information displayed on the screen of the display unit 40, of the data memory 50. After storing at the predetermined address # 1, the wireless terminal is automatically switched to the call mode, and if the call is not terminated, the call is continuously made with the other party (S5).

If there is no numeric information to be received in step S2 of determining whether to receive the numeric information from the counterpart terminal, the wireless terminal user determines whether to terminate the call and continuously performs the call otherwise. (S6).

Subsequently, the user searches for numerical information stored at a predetermined address (# 1) of the data memory 50 using the search key of the key input unit 70 and displays it on the screen, or displays it on the screen using the delete key. You can also delete numeric information.

In addition, the numerical information may be transmitted to other wireless terminal users in the same manner as in FIG. 3.

Although specific embodiments of the present invention have been described and illustrated in FIGS. 1 to 3, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

Therefore, in the present invention, during the call with the other party using the wireless terminal, the number related information to be communicated by the other party is accurately received and displayed using a simple key operation and stored in a memory, and the numeric information received by the user as needed. Can be searched and used or deleted arbitrarily, so that various numeric information messages such as the phone number, account number and social security number of the other party can be accurately and easily even when there is no writing device or other recording medium to record the numeric information during the call. Not only can it receive it, but it can be used more effectively.
