Description

핸드프리용 스피커가 내장된 이동통신 단말기의 제어방법 {a method for controlling the mobil communication terminal device with a speaker for hand- free}Control method of a mobile communication terminal with a built-in handfree speaker {a method for controlling the mobil communication terminal device with a speaker for hand-free}

본 발명은 이동통신 단말기의 제어방법에 관한 것으로, 특히 운전중이거나 작업중에 전화가 걸려와도 단말기를 들지 않고서 상대방과 통화할 수 있는 핸드프리용 스피커가 내장된 이동통신 단말기의 제어방법에 관한 것이다.The present invention relates to a control method of a mobile communication terminal, and more particularly, to a control method of a mobile communication terminal having a built-in speaker for a hand-free speaker that can talk to the other party without picking up the terminal even when a call is made while driving or working. .

일반적으로, 이동통신은 무선으로 신호를 송·수신함에 따라 언제, 어디서나 상대방과 통화할 수 있다는 잇점으로 인해 대중화되고 있다. 도 3은 이와같은 이동통신에서 사용되는 일반적인 단말기의 구성을 개략적으로 나타낸 블럭도이다.In general, mobile communication is popularized due to the advantage of being able to talk to the other party anytime and anywhere as it transmits and receives signals wirelessly. 3 is a block diagram schematically illustrating a configuration of a general terminal used in such a mobile communication.

도면에 도시된 것처럼, 이동통신 단말기는 안테나(ANT)를 통해 신호를 송·수신하는 무선통신부(170)와, 상기 무선통신부(170)를 통해 수신된 신호를 디코딩하여 수화기(150)로 출력하고 마이크(160)를 통해 입력된 신호를 인코딩하여 출력하는 코덱(CODEC)(140)과, 상기 무선통신부(170)를 통해 수신된 신호를 가공하여 코덱(140)으로 인가하며 코덱(140)에서 인코딩된 신호를 가공하여 무선통신부(170)로 인가하는 ASIC(120)으로 이루어져 있다.As shown in the figure, the mobile communication terminal decodes the signal received through the wireless communication unit 170 and the wireless communication unit 170, and transmits and receives the signal through the antenna (ANT) and outputs to the receiver 150 A codec 140 for encoding and outputting a signal input through the microphone 160 and a signal received through the wireless communication unit 170 are processed and applied to the codec 140 and encoded by the codec 140. The processed signal is composed of an ASIC 120 to be applied to the wireless communication unit 170.

또한, 전화번호 등을 입력하기 위한 키입력부(180)와, 상기 키입력부(180)를 통해 입력된 전화번호와 단말기의 동작상태를 나타내는 표시부(110)와, 상기 키입력부(180)를 통해 입력된 전화번호 등을 저장하는 메모리부(190), 및 내장된 프로그램에 따라 단말기의 전체동작을 제어하는 중앙처리장치(130)를 포함한다.In addition, a key input unit 180 for inputting a phone number, etc., a phone number input through the key input unit 180 and a display unit 110 indicating an operation state of the terminal, and input through the key input unit 180 Memory unit 190 for storing the telephone number and the like, and a central processing unit 130 for controlling the overall operation of the terminal according to the embedded program.

이와같이 구성된 이동통신 단말기는 상기된 것처럼 안테나(ANT)를 통해 신호를 무선으로 송·수신함에 따라 언제, 어디서나 상대방과의 통화를 가능하게 한다.As described above, the mobile communication terminal configured as described above enables communication with the other party anytime and anywhere by wirelessly transmitting and receiving signals through the antenna ANT.

그러나, 이동통신 가입자가 차량을 운전하는 도중에 전화가 걸려오면 한손으로는 차량의 핸들을 잡고 운전을 하며 다른 한손으로는 단말기를 들고 통화를 하여한다. 따라서, 운전에 집중하지 못함에 따라 교통사고를 유발시키는 경우가 있다.However, when a mobile communication subscriber receives a phone call while driving a vehicle, the mobile communication subscriber holds the handle of the vehicle with one hand and drives the vehicle while holding the terminal with the other hand. Therefore, there is a case where a traffic accident is caused by being unable to concentrate on driving.

이러한 문제점을 해결하기 위하여 단말기를 들지 않고서도 상대방과 통화할 수 있는 차량용 핸드프리세트가 제공되고 있다. 이 핸드프리세트(200)는, 도 4에 도시된 것처럼 차량의 시거잭에 접속되는 전원단자(210)와, 이동통신 단말기(100)를 통해 수신된 신호를 스피커(230)로 출력하고 마이크(240)로 입력된 신호를 상기 단말기(100)를 통해 송신하는 제어부(220)로 구성되어 있다.In order to solve this problem, a vehicle hand preset capable of talking with the other party without carrying a terminal has been provided. As shown in FIG. 4, the hand preset 200 outputs a signal received through the power supply terminal 210 connected to the cigar jack of the vehicle and the mobile communication terminal 100 to the speaker 230 and the microphone 240. The control unit 220 transmits a signal input through the terminal 100.

따라서, 차량의 일측에 설치된 거치대에 이동통신 단말기(100)를 장착하고, 이 단말기(100)의 접속단자에 핸드프리세트(200)의 접속단자를 결합한 후, 시거잭에 전원단자(210)를 접속하면 이동통신 단말기(100)의 중앙처리장치(130)는 인가되는 외부전원, 다시말해 차량의 배터리로 부터 인가되는 외부전원에 따라 단말기 (100)의 동작모드를 핸드프리모드로 절환시킨다.Therefore, the mobile communication terminal 100 is mounted on a cradle installed on one side of the vehicle, the connection terminal of the hand preset 200 is coupled to the connection terminal of the terminal 100, and then the power terminal 210 is connected to the cigar jack. The central processing unit 130 of the mobile communication terminal 100 switches the operation mode of the terminal 100 to the hand free mode according to the external power applied, that is, the external power applied from the battery of the vehicle.

즉, 이동통신 단말기(100)의 중앙처리장치(130)는 외부전원이 검출되면 내장된 제어프로그램에 따라 코덱(140)의 신호 입출력 경로를 내장된 수화기(150)와 마이크(160)로 부터 핸드프리세트(200)의 스피커(230)와 마이크(240)로 변경한다. 따라서, 이후에 걸려오는 전화는 핸드프리세트(200)를 통해 통화가 가능하게 된다.That is, when an external power source is detected, the central processing unit 130 of the mobile communication terminal 100 transfers the signal input / output path of the codec 140 from the built-in handset 150 and the microphone 160 according to a built-in control program. The speaker 230 and the microphone 240 of the preset 200 are changed. Therefore, the incoming call can be made through the hand preset 200.

그러나, 상기와 같은 차량용 핸드프리세트는 단말기와 별도로 구입하여 차량에 장착하여야 함에 따라 추가적인 비용이 발생하게 되며, 또한 핸드프리세트의제어부가 마이크와 스피커 및 전원단자와 와이어로 연결되어 있음에 따라 설치에 어려움이 있다.However, the vehicle hand preset as described above is purchased separately from the terminal and installed in the vehicle, which incurs an additional cost, and is also installed as the control unit of the hand preset is connected with a microphone, a speaker, and a power terminal. There is a difficulty.

아울러, 모든 통화가 핸드프리세트를 통해 이루어짐에 따라 비밀통화를 위해서는 이동통신 단말기의 접속단자와 핸드프리세트의 접속단자를 분리하고 단말기의 동작모드를 일반통화모드로 절환시킨 후, 통화를 하여야 한다는 불편함이 있으며, 또한 차량내에서만 사용이 가능하다는 문제점도 있다.In addition, as all calls are made through the hand preset, for the secret call, the user must disconnect the connection terminal of the mobile communication terminal and the connection terminal of the hand preset, switch the operation mode of the terminal to the general call mode, and then make the call. There is an inconvenience, and there is also a problem that can be used only in the vehicle.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 키입력에 따라 수신된 신호를 내장된 수화기나 스피커로 선택적으로 출력함에 따라 별도의 핸드프리세트를 구입하여 설치하지 않아도 단말기를 들지 않고서 상대방과 통화할 수 있는 핸드프리용 스피커가 내장된 이동통신 단말기의 제어방법을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been invented to solve the above problems, by selectively outputting the received signal according to the key input to the built-in handset or speaker without having to purchase and install a separate hand preset without lifting the terminal It is an object of the present invention to provide a control method of a mobile communication terminal having a built-in speaker for hands-free communication with the other party.

And a fourth step indicating that the signal is received, and when the operation mode of the terminal is switched to the hands-free mode, amplifying the received voice signal and outputting the received voice signal to the speaker. When described in detail with reference to as follows.

도 1은 본 발명이 적용되는 핸드프리용 스피커가 내장된 이동통신 단말기를 나타낸 블럭도로, 안테나(ANT)를 통해 신호를 송·수신하는 무선통신부(18)에 수신된 신호 및 마이크(17)를 통해 입력되어 인코딩된 신호를 가공하는 ASIC(12)이 접속되어 있다.1 is a block diagram illustrating a mobile communication terminal having a built-in handfree speaker to which the present invention is applied. The signal and the microphone 17 received by the wireless communication unit 18 transmitting and receiving a signal through an antenna ANT are shown in FIG. The ASIC 12 which processes the signal which is input through the encoded signal is connected.

한편, ASIC(12)에 의해 가공된 수신신호는 코덱(CODEC)(14)에 의해 디코딩되어 설정된 단말기의 동작모드에 따라 내장된 핸드프리용 스피커(15)나 수화기(16)로 출력되며, 또한 마이크(17)를 통해 입력된 신호는 코덱(14)에 의해 인코딩되어 ASIC(12)로 출력된다.On the other hand, the received signal processed by the ASIC (12) is decoded by the codec (14) and output to the built-in hand-free speaker 15 or receiver 16 according to the operation mode of the set terminal, The signal input through the microphone 17 is encoded by the codec 14 and output to the ASIC 12.

내장된 프로그램에 따라 단말기의 전체동작을 제어하는 중앙처리장치(13)에는 전화번호 등을 입력하기 위한 키입력부(19)가 접속되어 있으며, 중앙처리장치 (13)는 키입력부(19)를 통해 입력된 전화번호와 단말기의 동작상태를 표시부(11)에 나타내고, 아울러 키입력부(19)를 통해 입력된 전화번호 등을 메모리부(20)에 저장한다.The central processing unit 13 for controlling the overall operation of the terminal according to the built-in program is connected to a key input unit 19 for inputting a telephone number, etc., the central processing unit 13 through the key input unit 19 The input telephone number and the operation state of the terminal are shown on the display unit 11, and the telephone number input through the key input unit 19 is stored in the memory unit 20.

다음에는 상기와 같이 구성된 이동통신 단말기에 적용되는 본 발명에 따른 제어방법을 도 2를 참조하여 설명한다.Next, a control method according to the present invention applied to the mobile communication terminal configured as described above will be described with reference to FIG.

이동통신 단말기에 전원이 인가되면 제 1 단계에서 중앙처리장치(13)는 키입력부(19)의 스위칭 상태를 검출하고 제 2 단계에서 현재 설정된 단말기의 동작모드에 대한 스위칭 절환이 있는지를 판단한다.When power is supplied to the mobile communication terminal, the CPU 13 detects the switching state of the key input unit 19 in the first step and determines whether there is a switching switch for the operation mode of the terminal currently set in the second step.

상기 제 2 단계에서 절환스위칭 입력이 있으면, 단말기의 동작모드가 일반통화모드로 설정되어 있을 경우 제 3 단계에서 중앙처리장치(13)는 안테나(ANT)를 통해 수신된 신호를 디코딩하는 코덱(14)의 신호출력경로를 내장된 핸드프리용 스피커(15)로 절환하는데, 신호가 수화기(16)로 출력되는 경우 보다 음량이 크도록 증폭하여 스피커(15)로 출력하며 또한 표시부(11)에는 단말기의 동작모드가 핸드프리모드로 절환되었음을 나타낸다.If there is a switching switching input in the second step, when the operation mode of the terminal is set to the general call mode, in the third step, the CPU 13 decodes a signal received through the antenna ANT.
