본 발명은 셀룰라폰의 톤신호송출방법에 관한 것으로, 특히 셀룰라폰에 저장된 전화번호를 다이얼링하여 일반전화기를 통해 전화 통화하는 경우 셀룰라폰에 메모리된 전화번호의 검색후에 톤신호 송출버튼을 사용하여 일반전화기의 송화기에 톤다이얼링 함으로써 일반전화 통화시의 사용 편리성을 향상시킴과 동시에 저렴한 통화가 가능하도록 하는 셀룰라폰의 톤신호송출방법에 관한 것이다.The present invention relates to a method for transmitting a tone signal of a cellular phone. In particular, when dialing a telephone number stored in a cellular phone to make a telephone call through a general telephone, a general purpose of using a tone signal transmitting button after searching for a telephone number stored in the cellular phone The present invention relates to a method for transmitting a tone signal of a cellular phone, which improves the convenience of use in a general telephone call and enables a low-cost call by tone dialing a telephone transmitter.
일반적으로 셀룰라폰은 이동하면서 통화할 수 있다는 장점 때문에 이동 통신 수단으로 널리 이용되고 있다. 그러나 셀룰라폰은 통화요금이 일반 유선전화 보다 비싸기 때문에 이동하지 않는 상태에서 통화하는 경우에는 주변의 일반 유선전화기를 사용하여 통화하는 것이 보편화되어 있다.In general, the cellular phone is widely used as a mobile communication means due to the advantage of being able to talk while moving. However, since cellular phone calls are more expensive than ordinary landline phones, it is common to use a general landline phone when a phone call is not moved.
이와 같이 셀룰라폰 사용자가 일반 유선 전화기를 사용하여 통화하고자 하는 경우 상대방의 전화번호를 직접 다이얼링해야 하는 번거로운 점이 있었다.As such, when a cell phone user wants to make a call using a general landline telephone, there is a cumbersome point of having to dial the phone number of the other party directly.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로 셀룰라폰에 기억된 전화번호가 하드웨어적으로 일반 유선 전화기의 송화기에 직접 톤다이얼링 되도록 함으로써 유선전화기 사용할 때에 직접 다이얼버튼의 조작을 하지 않더라도 통화할 수 있도록 하는 셀룰라폰의 톤신호 송출방법을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, so that the telephone number stored in the cell phone can be dialed directly to the telephone of a general landline telephone by hardware, so that the user can make a call even without using a direct dial button when using a landline telephone. The purpose of the present invention is to provide a method for transmitting a tone signal of a cellular phone.
상기한 목적을 달성하기 위한 본 발명의 특징은, 셀룰라폰의 톤신호송출방법에 있어서 셀룰라폰의 메모리에 전화번호를 저장하는 단계와; 셀룰라폰의 메모리에 저장된 전화번호를 스캐닝하여 수화자전화번호를 선택하는 단계와; 선택된 수화자전화번호에 대응하는 DTMF톤신호를 발생하여 일반 유선전화기의 송화부에 송출해서 다이얼링하는 단계를 포함하는데 있다.A feature of the present invention for achieving the above object comprises the steps of: storing a telephone number in a memory of a cellular phone in a tone signal transmission method of a cellular phone; Selecting a called party number by scanning a telephone number stored in a memory of the cellular phone; And generating a DTMF tone signal corresponding to the selected called party's telephone number and sending it to a transmitter of a general landline telephone for dialing.
본 발명의 바람직한 실시예에 따르면, 상기 DTMF톤신호 발생송출단계에서는 전화번호의 디지트를 하나씩 순서대로 독취하여 대응되는 DTMF톤신호를 발생하여 내부 타이머에 의해 계속되는 소정 시간 동안 송출하는 것을 특징으로 한다.According to a preferred embodiment of the present invention, in the DTMF tone signal generation and sending step, the digits of the telephone numbers are read one by one to generate corresponding DTMF tone signals, and are transmitted for a predetermined time period continued by an internal timer.
이하, 본 발명에 대해 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명이 적용된 DTMF 톤신호 발생 셀룰라폰의 구성도로서, 10은 안테나(ANT)를 통한 데이터의 교환을 행하기 위한 듀플렉서이고, 11과 12는 주파수 합성부(13)에서 발생되는 합성주파수신호를 인가받아 전화메세지를 송, 수신하는 수신부와 송신부이며, 14는 전화메시지등과 같은 오디오신호를 처리하는 오디오/논리제어부로서, 본 발명을 위한 DTMF톤 발생장치(15)가 내장된다. 16은 전화기 전체의 동작을 제어하면서 본 발명에 따른 DTMF톤 신호발생 및 송출기능을 제어하는 마이크로프로세서를 채용한 제어부이고, 17 ~ 19는 각종 데이터의 저장이라던지 동작프로그램의 저장, 특히 수화자의 전화번호가 등록되는 메모리이다. 20은 셀룰라폰의 동작상태를 표시하는 LCD표시부이고, 21은 기능설정이라던지 전화번호의 입력을 위한 키패드부로서 통상 셀룰라폰의 상부패널과 같은 적절한 부위에 설치된다. 22는 호출음 또는 오디오데이터의 출력을 위한 스피커이고 23은 오디오데이터의 입력을 위한 마이크이다.1 is a configuration diagram of a DTMF tone signal generating cellular phone to which the present invention is applied, wherein 10 is a duplexer for exchanging data through an antenna ANT, and 11 and 12 are synthesis generated by the frequency synthesizer 13. A receiving unit and a transmitting unit for receiving and transmitting a frequency message by receiving a frequency signal, 14 is an audio / logical control unit for processing an audio signal such as a telephone message, etc., and a DTMF tone generating device 15 for the present invention is incorporated. 16 is a control unit employing a microprocessor for controlling the operation of the entire DTMF tone signal generation and transmission according to the present invention, while controlling the operation of the entire phone, 17 to 19 is the storage of various data or the operation program, in particular the telephone of the receiver The memory whose number is registered. 20 is an LCD display unit for displaying the operation state of the cellular phone, and 21 is a keypad unit for inputting a phone number for setting a function or the like, and is usually installed at an appropriate portion such as an upper panel of the cell phone. 22 is a speaker for output of a ring tone or audio data and 23 is a microphone for input of audio data.
이와 같이 구성된 셀룰라폰은 주지된 바와 같이 동작하여 전화메시지의 교환이 이루어지게 된다. 여기서 제2도와 제3도를 참조하여 본 발명에 따른 톤신호 송출동작에 대해 설명한다.The cellular phone configured as described above operates as is well known to exchange telephone messages. Here, the tone signal transmitting operation according to the present invention will be described with reference to FIG. 2 and FIG.
먼저, 제2도는 셀룰라폰에서의 통화모드와 톤발생모드의 분기동작을 설명한 플로우차트로서 단계 S21에서는 제어부(16)의 제어하에 메모리(18)에 저장된 전화번호를 스캐닝하여 단계 S22에서 수화자전화번호를 선택하게 된다. 이 전화번호의 선택후, 단계 S23에서 셀룰라폰의 키패드부(21)에 구비된 송신버튼을 조작하면 단계 S24에서 선택된 수화자전화번호가 송신되는 반면, 단계 S25에서 DTMF톤신호 송출버튼을 조작하면 제어부(16)의 제어하에 오디오/논리제어부(14)내의 DTMF톤신호 발생장치(15)에서 톤신호가 발생되어 단계 S26에서 일반전화기의 송화기에 톤다이얼링 신호가 다이얼링되고, 이어 단계 S27에서 톤다이얼링된 전화번호가 송신된다.First, FIG. 2 is a flowchart illustrating the branching operation of the call mode and the tone generation mode in the cellular phone. In step S21, the telephone number stored in the memory 18 is scanned under the control of the controller 16, and the telephone receiver is called in step S22. The number will be selected. After the telephone number is selected, when the transmit button provided in the keypad 21 of the cellular phone is operated in step S23, the telephone number of the called party selected in step S24 is transmitted, while the DTMF tone signal transmitting button is operated in step S25. Under the control of the control unit 16, the tone signal is generated in the DTMF tone signal generator 15 in the audio / logical control unit 14, and the tone dialing signal is dialed to the talker of the general telephone in step S26, followed by the tone dialing in step S27. Telephone number is sent.
좀 더 구체적으로 설명하면 셀룰라폰의 아이들(idle)모드 상태에서 키패드부(21)를 조작하여 RCL + XX를 입력하면 XX번에 기억된 전화번호가 LCD표시(20)상에 표시되고, 이 상태에서 DTMF톤신호 송출버튼을 조작하면 톤신호 송신모드로 되어 제3도 단계 S31에서처럼 제1디지트를 위하여 그 디지트에 할당된 DTMF톤신호가 DTMF발생장치(15)에서 발생되어 스피커(22)를 통해 일반 유선 전화기의 송화기에 송출된다. 이러한 송출은 내부타이머에 의한 계수시간이 종료될 때까지 제1디지트의 톤신호 송출후 그 후속 디지트에 대해 반복적인 톤신호 발생동작이 수행되고, 최종 디지트에 해당하는 톤신호가 송출되면 통화가능 상태로 된다.In more detail, when the RCL + XX is input by operating the keypad 21 in the idle mode of the cellular phone, the telephone number stored at XX is displayed on the LCD display 20, and this state When the DTMF tone signal transmitting button is operated at, the tone signal transmission mode is entered, and the DTMF tone signal assigned to the digit for the first digit is generated in the DTMF generator 15 as shown in step S31 of FIG. It is sent to the handset of a regular landline telephone. Such transmission is performed by repeating the tone signal of the first digit until the end of the counting time by the internal timer, and then performing the repeated tone signal generation operation for the subsequent digit, and when the tone signal corresponding to the last digit is transmitted, the call is available. It becomes
상기한 바와 같이 본 발명에 따르면 셀룰라폰의 메모리에 저장된 전화번호를 선택하여 일반 유선 전화기의 송화기에 DTMF톤신호를 송출하게 되므로 일반 유선 전화기를 사용하는 경우 전화번호의 기억이 불필요하게 될 뿐만 아니라 직접 전화버튼을 조작해야 할 필요성도 배재된다. 더욱이 본 발명에 따른 톤신호송을 방법에 의하면 일반 유선 전화기를 편리하게 사용할 수 있게 하므로, 통화료의 절감효과가 기대될 수 있는 장점이 있다.As described above, according to the present invention, since the DTMF tone signal is transmitted to the transmitter of the general landline phone by selecting the phone number stored in the memory of the cellular phone, the memory of the phone number is not only necessary when using the landline phone directly. The need to operate the phone buttons is also excluded. Furthermore, according to the method for transmitting a tone signal according to the present invention, it is possible to conveniently use a general landline telephone, and there is an advantage that a reduction in call charges can be expected.
