Method and device for automatic dialing of sequence number in telephone terminal

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone terminal, and more particularly, to a method and an apparatus for automatically dialing a sequence number of a telephone terminal, which is capable of automatically dialing the next phone number by a simple key operation when the dialed number is busy.

The telephones, which are widely used throughout our living spaces, including homes and businesses, are the most basic necessities of modern people in the information age. Recently, the telephone function as a simple call device has been provided for this role. Increasingly, telephone terminals with various and convenient functions are emerging.

Also, in recent years, as the communication technology is rapidly developed, a mobile phone terminal has been developed and utilized in which an individual can communicate with another person while moving from an arbitrary place or from one place to another.

1 is a block diagram showing the internal structure of the above-mentioned mobile telephone terminal among telephone terminals.

In the drawing, reference numeral 10 denotes a terminal for communication by receiving a channel from a base station, 11 denotes an antenna for transmitting and receiving data with the base station, and 12 denotes a low noise amplifier (LNA) for amplifying a frequency signal received by the antenna 11. A low noise amplifier section 13 consisting of a low noise amplifier, etc., 13 is a demodulation section that demodulates an original code signal from a frequency signal inputted through the low noise amplifier section 12.

Further, reference numeral 14 denotes interleaving, block coding, and convolutional coding for data transmitted and received through the demodulator 13 and the modulator 19 to be described later. A base band circuit 15 for executing coding is a LAPDm processor for processing control data transmitted and received according to a LAPDm standard with a base station.

Further, 16 is a speaker for outputting an audio signal from an opposite station terminal in an audible voice, 17 is a microphone for converting and inputting a user's voice input into an electric voice signal, and 18 is an analog voice signal input from the microphone 17. Converts the digital data into digital data, converts the voice data applied through the baseband processor 14 into an analog voice signal, and outputs the voice data to the speaker 16.

Reference numeral 19 denotes a modulator for modulating the transmission data output through the baseband processor 14 into a predetermined frequency signal, and 20 denotes an amplifier for amplifying the frequency signal modulated by the modulator 19. .

Reference numeral 21 denotes a key input unit having a plurality of numeric keys and function keys, 22 denotes a display unit such as a liquid crystal display (LCD) for displaying various operating states or operating states of the terminal, and 23 denotes a terminal of the terminal. A control unit for controlling the terminal according to the operation signal input through the key input unit 21, the operation state of the use state, 24 is a program memory in which the operation program of the control unit 23 is stored, 25 is the control unit ( It is a data memory that stores various processing data related to the operation of (23).

Further, reference numeral 26 denotes an analog / digital converter for digitally converting the received data demodulated by the demodulator 13 and outputting a data value corresponding to the received power level to the controller 23, which is a base station of the terminal. It is provided for selection or handover function.

That is, in the terminal having the above-described configuration, when the user turns on the power of the terminal 10, the controller 23 is received through the antenna 11 while sequentially increasing or decreasing the demodulation frequency of the demodulator 13. In addition to searching the wireless carrier, the base station to which it belongs is identified based on the level of each demodulated signal input through the A / D converter 26. At this time, the controller 23 stores the control data for controlling the demodulator 13 and the level value of the received data input through the A / D converter in the data memory 25 and then has the highest level value. The demodulation frequency of the demodulator 13 is set based on the reception frequency.

Then, the control unit 23 receives the broadcast channel from the base station received by the demodulator 14, grasps the information of the base station, and then transmits its own information through the baseband processor 15 and the modulator 19. The registration procedure is performed by transmitting to the base station.

Accordingly, when the base station receives the terminal information from the terminal 10, the base station transmits the terminal information to the base station controller (not shown), and the base station controller transmits the terminal information to the authentication center (not shown) through the exchange (not shown). ), It is checked whether the terminal 10 is legally registered.

If the terminal 10 is normally registered, the base station controller sends the encryption code to the terminal 10 through the base station to register the terminal 10 in a usable state.

In the state where the terminal 10 is normally registered as described above, when the user operates the key input unit 21 and there is a transmission request (call request) to the base station, the control unit 23 detects the key input and then the base station. A random access channel (RACH: Random Access Channel) is sent out for the connection request. At this time, an access grant channel (AGCH) is received from the base station or a voice signal is transmitted / received through an assigned time slot so that a call can be made with another terminal.

On the other hand, when the terminal 10 is registered in the usable state, when there is a large number of terminals possessed by the counterpart party (for example, 3452-1431 to 3), one of the telephone numbers is inputted. When dialing, when the dialed terminal is in a call, the controller 23 transmits a busy tone through the voice processor 18 and a speaker.

Then, the user hears this and presses the END key provided on the key input unit 21 and then presses the SEND key again to key in another telephone number to dial.

In addition, if the terminal of the dialed telephone number is busy, the user performs a cumbersome operation of keying another telephone number again.

Accordingly, the present invention has been made in view of the above circumstances, and provides a method and an apparatus for automatically dialing a sequence number of a telephone terminal which enables the next telephone number to be automatically dialed by a simple key operation when the telephone terminal of the dialed number is busy. The purpose is to provide.

First, after identifying the base station to which the mobile terminal belongs according to the present invention performs a registration procedure for the base station in the standby mode registered in the usable state (step ST1), if the telephone number by the user is input (step ST2) ) The control unit 33 generates a DTMF signal corresponding to the number input through the DTMF generation circuit 34, modulates it through the modulator 19, and then transmits the signal wirelessly through the antenna 11. The number is stored in the data storage unit 31 (ST3 step).

After that, if the call terminal is not in a call, the control unit 33 makes a phone call or performs other normal control processing and ends (ST4 step).

On the other hand, when receiving a busy signal from the call terminal (step ST5), the control unit 33 controls the voice processing unit 18 to transmit the busy tone through the speaker 16, and then can continuously call its own mode. Mode is entered (ST6).

In the state of switching to the continuous call mode, when a volume down key is input by the user (step ST7), the control unit 33 changes the line and then stores the telephone number stored in the data storage unit 31. Is read out to reduce the last digit by one (ST8 step), and the DTMF generation circuit 34 generates and sends a DTMF signal corresponding to the reduced number (step ST9).

In addition, in the state of switching to the continuous call mode, if the user inputs an UP key instead of a DOWN key (step ST10), the control unit 33 switches the line in a call and then the data storage unit ( Read the telephone number stored in 31) and increase the last digit by 1 (step ST11), and generate the DTMF signal corresponding to the increased number through the DTMF generating circuit 34 to modulate the antenna 19 and the antenna. Radio transmission is performed through step 11 (ST12 step).
