Abstract

A method for controlling a mobile terminal having a projector function is provided to prevent a caller from unnecessarily attempting call or message origination by automatically sending a response message to inform the caller, who has made a call or has sent a short message, that a projector function is being executed. A control part in a mobile terminal confirms whether the user inputs a projector selection button or a key to execute a projector function(S11). If a key associated with the execution of the projector function is inputted, the control part makes the user select a notification mode for calls or short messages to be received during the execution of the projector function(S15). If the user selects contents to be projected on an external screen after selecting a notification mode(S17), the control part controls a projector module so that the selected contents can be projected on the external screen(S19). If a call or a short message is received(S21), the control part judges whether the mobile terminal is in idle mode(S23). In case that the mobile terminal is in idle mode, the control part intercepts the notification of the received call or short message by controlling associated parts of the mobile terminal so as not to operate all the notification units(S27). The control part confirms the caller number received together with the call or the short message and sends an automatic response message to inform the caller, who has made the call or has sent the short message, that the projector function is being executed.

3 is a flowchart illustrating a control method of a mobile communication terminal having a projector function according to the present invention, and the subject is a control unit 210.

First, in step S11, it is checked whether there is a key input for the projector selection button 115 or the protector function from the terminal user. As a result of the check in step S11, if the key input is an input not related to performing the projector function, the process proceeds to step S13 to perform a function related to the key input. By selecting the operation mode of the mobile communication terminal, that is, the notification mode of the call or text message received during the week of performing the projector function. Here, the notification mode of the terminal is a standby mode for blocking the reception notification of the call or text message when performing the projector function, the silent mode for visually displaying the reception notification through the LED 272, and the reception notification vibration motor 272 It is classified into a vibration mode for vibrating the terminal through and a ringtone mode for outputting sound through the speaker 254.

On the other hand, after the notification mode is selected in step S15, the next step S17 receives the content to be projected on the external screen from the terminal user. In this case, the projection content may be various images or document information stored in the memory 240, or may be image information displayed on the flat panel display 262. Next, in step S19, the projector module unit 286 is controlled so that the image information or document information selected in step S17 is projected on the external screen.

Next, in step S21, it is checked whether a call or a text message is received through the radio frequency transmitter / receiver 220. If no call or text message is received as a result of the confirmation in step S21, the flow proceeds to step S35, whereas if the call or text message is received, the flow proceeds to step S23. In operation S23, it is determined whether the operation mode of the terminal is in the standby mode. If the determination result is in the silent mode, the vibration mode, or the ring mode, the process proceeds to step S25 to correspond to each mode. Each part of the terminal is controlled to operate the notification means, that is, the speaker 254, the LED 276, or the vibration motor 272.

On the contrary, when the determination result in step S23 is that the operation mode of the terminal is in the standby mode, the terminal proceeds to step S27 so that all the notification means, that is, the speaker 254, the LED 276, or the vibration motor 272 are not operated. By controlling the unit, a call or text message reception notification that is an obstacle to performing the projector function is blocked.

Next, in step S29, the caller's telephone number provided with the call or the text message is checked to answer the caller who attempted the call or sent the text message to the caller who sent the text message. A short message containing the contents of the message is transmitted, and in step S33, the caller's telephone number or the text message contents are stored. Of course, the contents of the auto-reply message should be stored in advance in the data storage unit 244, and also, the mobile communication terminal according to the present invention, in order to transmit the auto-reply message, can be provided with caller information. It is desirable to subscribe to a Calling Number Identification Presentation (CNIP) or Calling NAme Presentaion (CNAP).

Next, in S35, it is determined whether the projector function is terminated, that is, whether there is a key input related to the end of the projector function from the user. If the projector function is not terminated as a result of the determination, the process returns to step S19. On the other hand, if the projector function is terminated as a result of the determination in step S35, the process proceeds to step S37 to notify the terminal user that the received caller information or the text message has arrived when the terminal operation mode state is the standby mode.

The method of controlling the mobile communication terminal having the projector function of the present invention is not limited to the above-described embodiments, and various modifications can be made within the range allowed by the technical idea of the present invention.
