Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the apparatus of the present invention is installed on a part of the body of the mobile communication terminal 1 and displays an LCD panel 2 for displaying various information signals processed by the terminal to the outside, and the mobile communication terminal 1 After measuring the RPM of the vehicle according to the detection control signal of the transmission to the mobile communication terminal (1) as a wireless signal and the RPM detection sensor 10 is installed on one side of the engine driver of the vehicle and the mobile communication terminal (1) When the incoming call signal is received, the vehicle checks whether the vehicle is running through the RPM detection sensor 10, and automatically performs a hands-free function according to the user's request to process the incoming call and function of the mobile communication terminal (1). A mobile station modem (3) for controlling the overall, a memory unit (4) for storing various information processed in the mobile communication terminal (1) in accordance with the storage control signal of the MSM (3), and In accordance with the call connection control signal of the MSM unit (3) Converts the analog voice signal inputted through the equalizer 5 to the digital signal, or including the codec unit (6) which converts the digital voice signal into an analog signal.

One end of the MSM unit 3 is connected to a key panel unit 7 for inputting a function setting signal of the user to the MSM unit 3.

Next, a control method applied to the terminal of the present invention as described above will be described.

As shown in FIG. 3, the method of the present invention proceeds to the call signal reception confirmation step S2 in the initial state S1 to check whether the wireless call signal is received at the current terminal. At this time, if the wireless signal is not received in the current terminal as a result of the call signal incoming confirmation step (S2) proceeds to the general terminal menu execution step (S3) and executes the general terminal menu provided in the mobile communication terminal. However, if the wireless call signal is received at the current terminal as a result of checking during the call signal reception confirmation step (S2), the process proceeds to the vehicle driving search step (S4) and checks whether the vehicle is currently running through the sensor, and then the current wireless call signal. A bell signal is sent to the outside indicating that the call has been received. After the vehicle driving search step S4, the vehicle driving check step S5 is performed to check whether the vehicle is currently in operation. If the vehicle is not currently in operation as a result of checking during the vehicle operation checking step (S5), the process proceeds to the general call processing step (S6) to connect a radio call to execute a call through the receiver.

That is, when power is applied to the terminal 1 of the present invention, the MSM unit 3 of the terminal 1 proceeds to an initialization state, forms necessary information from the memory unit 4, executes an initialization process, and then waits. Proceed to

At this time, the MSM unit 3 of the terminal 1 recognizes when the user inputs a telephone number through the key panel unit 7 and presses a call button, and the user inputs the telephone number to the memory unit 4. In addition to the storage, the system accesses the base station system unit 8 through the access channel, and then transmits an outgoing signal to the corresponding telephone number. Then, the base station system unit 8 processes the outgoing signal sent from the terminal 1 and transmits an incoming call to the counterpart terminal 9 to form a call. That is, when the user of the terminal 1 inputs the voice signal through the handset 5, the codec unit 6 of the terminal 1 signals the voice signal input through the handset 6 to the MSM unit. Enter (3). The MSM unit 3 of the terminal 1 wirelessly processes a voice signal input through the codec unit 6 and transmits the voice signal to the counterpart terminal 9 via the base station system unit 8 so that a normal call can be made. Is achieved.

However, as a result of checking during the vehicle operation checking step (S5), if the vehicle is currently in operation, it proceeds to the incoming call request confirmation step (S7) to check whether the user who is driving the vehicle inputs a desired button signal while driving. At this time, when the incoming call request confirmation step (S7) is confirmed as a result of the user running the vehicle does not input the desired button signal during the incoming call proceeds to the automatic call transmission step (S8) and the terminal automatically incoming the current call Send a message to the other party indicating that the call is not available due to driving.

However, as a result of checking during the incoming call request confirmation step (S7), when the user operating the vehicle inputs a desired button signal for incoming call while driving, proceed to the hands-free mode execution step (S9) to automatically switch the terminal to the hands-free mode and then make a call. Run

In other words, when the wireless call is received by the terminal 1, the MSM unit 3 emits a bell signal indicating the incoming call to the outside and transmits and drives the wireless driving control signal to the RPM detection sensor 10. Then, the RPM detection sensor 10 checks whether the vehicle is currently running, and transmits the result to the MSM unit 3 by putting the result in a radio signal. Therefore, the MSM unit 3 analyzes the detection signal input from the sensor 10 to check whether the vehicle is currently running.

At this time, when the MSM unit 3 determines that the vehicle is not currently running based on the result value detected by the detection sensor 10, the MSM 3 proceeds to the normal terminal mode and the call mode through the receiver. Run

However, when the MSM unit 3 confirms that the vehicle is currently in operation based on the result value detected by the detection sensor 10, it is determined whether the user who is driving the vehicle inputs a desired button signal while driving. Check it.

Here, if the MSM unit 3 does not input a button signal for incoming call while the user who is driving the vehicle has elapsed a certain time, the MSM 3 automatically receives a current call and then informs that the call is impossible due to driving. The message is retrieved from the memory unit 4 and sent to the other party. On the other hand, the MSM unit 3 automatically switches the terminal to hands-free mode when the user who is driving the vehicle inputs a desired button signal while driving, and then executes a call as a normal hands-free through the handset 5.

 As described above, the present invention analyzes the vehicle operation information transmitted wirelessly from the RPM detection sensor provided in the vehicle when the radio call is received, and changes the current communication mode of the terminal to the hands-free mode according to the result. Since the user executes the call by executing the hands-free function as a mobile communication terminal without any additional manipulation, the user convenience of the terminal is also significantly improved.

In addition, according to the present invention, since the hands free function can be executed automatically through the mobile communication terminal without having a separate hands free device in the terminal, there is also an effect of significantly improving the functionality of the mobile communication terminal.
