Method of transmitting a telephone number of a cellular wireless communication terminal.

The present invention relates to a telephone number transmission in a mobile communication system. More particularly, the present invention relates to the transmission of a telephone number through a cellular wireless communication terminal in order to form a communication path between two parties. The present invention relates to a method for transmitting a telephone number of a cellular wireless communication terminal for counting a time for pressing a number to transmit a telephone number or a set telephone number including the last pressed number.

In general, a mobile communication system transmits a call message including a unique number of a called terminal through a call control channel of a base station to call a cellular wireless communication terminal to a cellular wireless communication terminal and then receives a call from the terminal. It is supposed to provide.

However, according to the protocol of the cellular radio communication terminal specified in the call processing of the Electronics Industry Association, the cellular radio communication terminal may miss the call message transmitted by the base station in a special situation. It is supposed to fail to call.

Such a general wireless communication terminal has a built-in transmission device and a reception device, and is a device that enables two-way communication at a long distance by using a radio signal to connect a line between a portable device and a fixed device of a general wireless phone. Its purpose is to pursue the convenience and mobility of telephone calls.

2 is a signal flow diagram of a method for transmitting a telephone number in a conventional cellular wireless communication terminal.

Referring to FIGS. 1 and 2, a method of transmitting a telephone number in a conventional cellular wireless communication terminal is described. First, when a user presses a call key through a keypad 113 to turn on a terminal for a two-way call (step ST10). In the non-call mode, the wireless communication terminal searches for a dedicated control channel of the base station 112 having the largest intensity, i.e., the closest base station, from the point where it is located (step ST11).

When the designated control channel of the nearest base station 112 is found, the wireless communication terminal receives and transmits a message transmitted by the base station 112 through the channel.

In the state in which the designated control channel of the base station 112 is selected through the non-call mode as described above, when the caller operates the keypad 113 (step ST12) and inputs the telephone number of the other party, the microprocessor 106 performs a program. As the program of the ROM 104 executes, the input telephone number is stored in the memory 105 and displayed on the liquid crystal display 107.

In this way, when the caller completes dialing through the keypad 113 to call the other party (step ST13), the microprocessor 106 inputs a Send Key 113a from the keypad 113. Search is made (step ST14).

At this time, when the caller presses the transmission key 113a of the keypad 113 to transmit the telephone number, the microprocessor 106 starts at this time the telephone number of the other party (the other party's call signal) stored in the memory 105. Is read and transmitted to the modulator 101 through the audio / logical controller 103 (step ST15).

The modulator 101 modulates the other party's dialing signal transmitted from the microprocessor 106 to the high frequency signal of the local oscillator 102 input by the control of the audio / logic controller 103 to transmit the high frequency transmitter 100. ).

The high frequency transmitter 100 amplifies the high frequency signal input from the modulator 101 and transmits the amplified signal to the base station 112 through the antenna ANT1. The base station 112 closest to the wireless communication terminal receives the received signal. One call signal is transmitted to the mobile communication switching center.

Therefore, after the mobile communication exchange station transmits a ring signal between the two parties to call the other party, if the other party does not receive the call for a predetermined time, it is determined that the call is failed (ST17) and the ring signal transmission is stopped.

Then, when the other party receives the call from above, the transmission of the ring signal is stopped from this time, thereby forming a two-way communication path (step ST16).

On the other hand, when the call path is formed through the step (ST16) and the voice signal and data from the other party is loaded on the high frequency through the corresponding base station 112 and through the antenna ANT1 of the wireless communication terminal high frequency receiving unit 111 Extracts only the required band from the received high frequency signal and amplifies it to a sufficient size to provide it to the demodulator 110.

The demodulator 110 extracts the intermediate frequency signal by mixing the input high frequency signal with the oscillation frequency of the local oscillator 102 and demodulates the extracted intermediate frequency signal into the original signal to the audio / logic controller 103. Will be provided.

The audio / logical controller 103 separates the voice signal and the data from the signal input from the demodulator 110, and outputs the voice signal through the speaker 109 and the data through the microprocessor 106. ) Is displayed.

On the other hand, during transmission, as a reverse process of the reception, the voice signal input from the microprocessor 106 is modulated to the high frequency signal through the audio / logic control unit 103 and the modulator 101 and then the high frequency transmitter 100 The power is amplified through and transmitted to the nearest base station 112, thereby making a call between the two parties (step ST18).

However, the conventional cellular wireless communication terminal described above is known that the caller's phone number is transmitted and made a call only when the caller presses the sender's phone number again after pressing the caller's phone number to be called through the keypad.

Therefore, in order to make a call between the two parties through the cellular wireless communication terminal, there is not only an inconvenience in operating the telephone number and the transmission key, but also the size of the keypad is increased due to the allocation of the transmission key to the keypad. The problem is that the size itself is not miniaturized and the size is increased.

Accordingly, the present invention excludes the inconvenience of having to press the transmission key simultaneously with the completion of dialing in the above-described prior art, and in one aspect of the present invention, transmits the other party's telephone number with the time of pressing the last number when the telephone number is transmitted. It is an object of the present invention to provide a method for transmitting a telephone number of a cellular wireless communication terminal to determine whether or not.

In another aspect of the present invention, it is an object of the present invention to determine whether or not to transmit a setting key, that is, a counterpart telephone number set with a pressing time of a shortcut key.

In still another aspect of the present invention, an object thereof is to simplify a keypad by deleting a transmission key for transmitting a telephone number.

When the input time of the last number and the setting key input time have not passed the setting time as determined by the steps ST106 and ST110, a re-entry message of the telephone number and the setting key is transmitted through the liquid crystal display unit 107. Displaying (ST112), searching for whether a call loop is formed between both sides after transmitting the dialing signal (telephone number) (ST113); and if the call loop is not formed as a result of the search, it is determined that the call has failed and the call If a loop has been formed, it is a step (ST114, ST115) to complete the call between the two parties.

Preferred embodiments of the present invention made as described above are described in detail below.

First, when the caller turns on the terminal for a call with the other party and presses the call key through the keypad 113 (step ST100), the microprocessor 106 of the cellular wireless communication terminal is located from the point where it is located in the non-call mode. The designated control channel of the base station 112 having the largest intensity of the received signal is found (step ST101).

When the designated control channel of the nearest base station 112 is found, the microprocessor 106 of the cellular wireless communication terminal receives the message transmitted by the base station 112 through the selected channel and transmits its own unique number. .

In the state in which the designated control channel of the base station 112 is selected through the non-call mode as described above, the caller operates the keypad 113 (step 102) and sequentially inputs the telephone number of the other party, but the last of the telephone numbers is inputted. When the number (the last number) is pressed for a predetermined time, the microprocessor 106 searches whether the serial telephone number from the keypad 113 is input (step ST103).

As a result of the search, if consecutive telephone numbers are sequentially input, the telephone numbers are combined and stored in the memory 105 according to the program execution of the program ROM 104, and the last number of the telephone numbers is stored through the time counting unit 114. The pressing time of the number is counted (step ST104).

Subsequently, it is determined whether dialing is completed through the keypad 113 (step ST105). If not, the process after step ST101 is repeated to input a phone number and if the dialing is completed, the microprocessor 106 is performed. ) Compares the pressing time of the final number counted by the time counting unit 114 with the reference time set in itself (step ST106).

The microprocessor 106 controls the liquid crystal display unit 107 to reset the telephone number when the pressing time of the last number, that is, the input time of the last number has not passed the set reference time as a result of the comparison in the step ST106. The input message is displayed in text (step ST112).

When the input time of the last digit has passed the reference time as a result of the comparison in the step ST106, the telephone number (dialing signal) including the last pressed digit is read from the memory 105 and the audio / logical control unit 103 is read. Through the modulator 101, the high frequency transmitter 100, and the antenna ANT1, the signal is transmitted to the base station 112 closest to the cellular radio communication terminal (ST107).

If it is not a consecutive telephone number in step ST103, a setting key assigned to the keypad 113, i.e., any one of the numeric keys, is searched (step ST108).

If any one of the numeric keys is inputted, the pressing time of the numeric keys (setting key) is counted through the time counting unit 114 in the same manner as described above (step ST109) and compared with the set reference time (step ST109). ST110).

As a result of the comparison in the step ST110, if the pressed time of the numeric key has not passed the set reference time, a re-entry message of the setting key is displayed as a text through the step ST112, and the pressed time of the numeric key is When the set time has elapsed, the corresponding telephone number stored in advance in the memory 105 in correspondence with the numeric key is read, and the audio / logical controller 103, the modulator 101, the high frequency transmitter 100 and the antenna ( ANT1) is transmitted to the base station 112 closest to the cellular radio communication terminal (ST111).

In another embodiment of the present invention, the next number is entered for a predetermined time even when a continuous telephone number, for example, a 114 telephone number is input in step ST103 and the pressing time of the final number has not passed the set time. If not input, the telephone number may be transmitted to the base station 112 through the antenna ANT1.

As a result, the same result as pressing a transmission key of the keypad of the prior art and transmitting a telephone number is obtained, thereby eliminating the necessity of disposing a separate transmission key on the keypad.

Subsequently, the base station 112 which has received the dialing signal from the cellular radio communication terminal transmits it to the mobile communication switching center.

In addition, the mobile communication switching station located between the base station 112 and the base station transmits a ring signal between the two parties until the other party receives the call. If the other party receives the call, the ring signal is stopped and the call loop is stopped. Will form.

Therefore, the microprocessor 106 determines whether the call loop is formed with the arrival of the ring signal (step ST113). If the call loop is not formed, the microprocessor 106 determines that the call has failed (step ST114).

When the call loop is formed in step ST113, the audio / logical control unit 103 is controlled to transmit the voice signal input from the microphone 108 to the base station through the modulation process and the amplification process, and the base station 112. The voice signal received from the other party is output to the speaker 109 through an amplification process and a demodulation process to make a call between the two parties (step ST115).

As described above, in the present embodiment, when the telephone number of the other party is transmitted, the telephone number including the last pressed number is transmitted or set by another method even when the last number is pressed for a few seconds without the transmission key provided in the keypad 113. When the key is pressed for a predetermined time, a telephone number corresponding to the setting key is transmitted to form a call loop, thereby simplifying the structure of the keypad due to deletion of the key.

In addition, although specific embodiments of the present invention have been described and illustrated above, 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.

It is clear from the above description that the telephone number transmission method of the cellular radio communication terminal of the present invention transmits the other party's telephone number only by pressing the last number or the setting time without pressing the transmission key when the telephone number is transmitted. In addition, the convenience of the transmission is provided as well as the effect of simplifying the keypad due to the deletion of the transmission key for transmitting the telephone number.
