The proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. Thus, proximity sensors have a considerably longer life than contact sensors and their utilization is also quite high.

Examples of the proximity sensor include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

To explain an example of the operation principle of the high frequency oscillation type proximity sensor, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface in the state of oscillating the high frequency wave of the wave in the oscillation circuit. This change is converted into an electrical signal to detect the presence or absence of a sensing object. Therefore, even if a non-metallic material comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

Even when the proximity sensor is not firmly mounted, when the touch screen is capacitive, the proximity sensor may be configured to detect the proximity of the pointer by a change in an electric field according to the proximity of the pointer.

Therefore, when the pointer is located in close proximity to the touch screen although it is not actually touched, the position of the pointer and the distance between the pointer and the touch screen may be detected. Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized on the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the pointer on the touch screen is referred to as "proximity touch". The act of actually contacting will be referred to as "contact touch". In addition, the position of the proximity touch with the pointer on the touch screen refers to a position where the pointer is perpendicular to the touch screen when the pointer is in proximity touch.

When the proximity sensor is used, a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) are detected, and the detection Information corresponding to the proximity touch operation and the proximity touch pattern may be output on the touch screen.

The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying occurrence of an event of the mobile communication terminal 100. Examples of events occurring in the mobile communication terminal include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than an audio signal or a video signal. For example, the signal may be output in the form of vibration. When a call signal is received or a message is received, the alarm unit 153 may output a vibration to inform this. Alternatively, when a key signal is input, the alarm unit 153 may output a vibration in response to the key signal input. Through the vibration output as described above, the user can recognize the occurrence of the event. Of course, the signal for notification of event occurrence may be output through the display module 151 or the voice output module 152.

As shown in FIG. 4, a broadcasting transmitter (BT) 295 transmits a broadcast signal to terminals 100 operating in the system. The broadcast module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT 295.

In addition, FIG. 4 illustrates multiple satellite positioning systems (GPS) satellites 300. The satellites 300 help to locate the at least one terminal of the plurality of terminals 100. Although two satellites are shown in FIG. 4, useful location information may be obtained by two or less or more satellites. The GPS module 115 shown in FIG. 1 cooperates with the satellites 300 to obtain desired location information. Here, the location can be tracked using all the techniques that can track the location, not just the GPS tracking technology. In addition, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

During typical operation of a wireless communication system, BS 270 receives a reverse link signal from various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by a particular base station 270 is processed within by the particular base station 270. The data generated as a result of the processing is transmitted to the connected BSC 275. BSC 275 provides call resource allocation and mobility management functionality, including the organization of soft handoffs between base stations 270. In addition, the BSC 275 transmits the received data to the MSC 280, and the MSC 280 provides an additional transmission service for connection with the PSTN 290. Similarly, PSTN 290 connects with MSC 280, MSC 280 connects with BSCs 275, and BSCs 275 send BSs 270 to transmit a forward link signal to terminals 100. ).

5 is an operation relationship diagram showing the progress of the application control method according to an embodiment of the present invention.

The terminal A runs the application while the call connection is connected between the two terminals (A, B). Call connection includes video call as well as voice call connection. The application below refers to an application requiring a screen display operation. For example, the mobile communication terminal according to the present invention has a multi-tasking function that can simultaneously drive digital broadcast signals, wireless Internet, or video coloring during voice calls or video calls. The broadcast receiving module 111 provided in the terminal receives a broadcast signal using various broadcast systems. A digital broadcast signal can be received using any one of DMB-T, DMB-S, MediaFLO, DVB-H, and ISDB-T.

The wireless Internet may be executed by using the internal or external wireless internet module 113. Voice call For example, wireless voice of any one of WLAN, Wibro, Wimax, and HSDPA may be executed during voice call using an ear-mic.

As such, the driving information of any one application implemented during the video call during the voice call may be transmitted to the counterpart terminal B. That is, the information in the form of a protocol is transmitted / received using a video call protocol. For example, while watching the same digital multimedia broadcast with a friend, it is possible to voice / video call / chat about the broadcast content. Alternatively, a user can view a web page on which a predetermined user created content (UCC) or a predetermined image is displayed while talking with a friend while executing the wireless Internet.

The terminal B displays the information received from the terminal A in a specific area of the screen. That is, the application corresponding to the command received from the counterpart terminal is executed.

6 is a flowchart illustrating a process of an application control method according to an embodiment of the present invention. An operation at terminal A for transmitting control information for application sharing is illustrated in FIG. 6A, and an operation at terminal B that receives control information and implements an application driven in terminal A in the same manner is illustrated in FIG. 6B.

Looking at the process of Figure 6a terminal A and terminal B is in the voice call / video call. During the call, the terminal A drives an application for watching digital broadcasting of a predetermined channel in its terminal (S611). If the user wants to watch the digital broadcast that he is currently watching with the counterpart terminal B currently on the call, the user selects a current screen sharing function by using a predetermined menu (S612). Accordingly, information about the application currently implemented through the terminal is transmitted to the counterpart terminal B. For example, channel information and control commands of the current digital broadcast are transmitted using a video call protocol such as 3G-324M or IMS (S613).

On the other hand, the process of the application control method according to the present invention in the terminal B is as follows. The user performs a call with the terminal A user (S621).

Application driving control information is received from the counterpart terminal A. In this case, it may be desirable to display a screen that asks whether to receive application driving information from the counterpart terminal. That is, a case in which another application is being driven while making a call with the counterpart terminal A may occur (S622).

Therefore, upon receiving the application driving control information from the counterpart, the application is driven according to the application control information received from the counterpart terminal A in response to the reception acceptance signal of the user (S623).

7 is an operation relationship diagram showing the progress of the application control method according to another embodiment of the present invention. Unlike the exemplary embodiment described with reference to FIG. 5, the terminal A is running an application. In other words, the terminal A while driving the wireless Internet or watching the digital multimedia broadcasting receives a call.

In this case, the call may be a voice call or a video call. In the case of a voice call, an ear microphone may be used for a call while shopping over the wireless Internet. If a user wants to share an application displaying the screen of the current terminal A with the other terminal B during a call, an application driving control of the other terminal B is performed by pressing a set menu or button.

For example, when watching a digital multimedia broadcast, the current broadcast channel information is included in the driving control signal and transmitted to the counterpart terminal B. In this case, the video call protocol may be used. When sharing the wireless Internet screen, the current Internet address is included in the driving control signal and transmitted to the counterpart terminal B.

The counterpart terminal B receiving the application driving control signal performs the same application performed on the terminal A according to the received signal. That is, the same web page may be displayed by watching digital broadcasting of the same channel or by performing internet access with the same internet address.

The operation flow in the terminal A performing the operation is as shown in the flowchart of FIG. 8.

The application is driven to watch a broadcast or perform wireless Internet (S801).

If a call is received while driving the application, the call is connected (S802).

If a need arises to share a screen by driving an application as necessary during a voice / video call, the application driving control information is transmitted to the counterpart terminal through a set menu or by using a function key provided separately (S803).

9 is an exemplary view showing an operation relationship according to another embodiment of the present invention.

Rather than simply sharing an application with a counterpart terminal, the operation state of the counterpart terminal is checked and control for driving an application of the counterpart terminal is shown.

When a call is connected between terminal A and terminal B, a voice / video call is performed.

The terminal A transmits a signal for requesting control right to the terminal B. The control right represents the authority for controlling the operation of the terminal B in the terminal A. On the screen of the terminal B, as shown in FIG. 10, a screen for notifying that the control right request signal has been received from the counterpart and receiving the user's selection signal for it is displayed. If the terminal B selects the acceptance, the terminal B transmits a control right accept signal to the terminal A. Whether the terminal A obtains the control right may be displayed on the screen according to the received signal or may be checked whether the function can be controlled through the menu function.

Subsequently, the terminal A transmits a "operating status confirmation request" signal to the terminal B in order to confirm the status information of the terminal B.

Since the control authority has already been accepted by the terminal A, the terminal B provides the current operating state information to the terminal A. That is, the parent can check the current state of the terminal operation of the child by obtaining a control right during the call with the child. However, such control right acceptance may be limited by the terminal B. That is, only the status information of the terminal B is transmitted to the terminal A, but the control right may not be granted.

The terminal A receives the operation state information from the terminal B and transmits a control command for the terminal B. That is, after confirming the operation state information of the terminal B, and transmits a signal for controlling the application driving of the counterpart terminal B. In this case, the driving control signal may be performed immediately, as well as a reserved control signal that may be driven at a predetermined time. For example, when the terminal B is the child's terminal, the parent of the terminal A, which has received the operation information indicating that the user is watching the music broadcast, may be controlled to switch to the education broadcast channel or may transmit a reservation signal for watching the education broadcast. In the description of this embodiment, an immediate execution of an application is taken as an example.

The terminal B receives the driving control signal and performs the application. If you are currently watching a music broadcast, a procedure for viewing a digital multimedia broadcast and a procedure for selecting an education broadcast channel are performed according to a driving control signal transmitted from the counterpart terminal A. Of course, each procedure is included in the driving control signal, so that the user of the terminal B does not need to perform a separate operation for processing. Of course, not only the viewing of digital multimedia broadcasting, but also the entry of the wireless Internet for classes through the Internet goes through a similar process.

The acknowledgment signal for informing the terminal A that the control command has been received after or during the execution of the application according to the driving control signal is transmitted.

Since the terminal A has completed the operation control, the terminal A transmits the control right revocation signal to the terminal B, and the terminal B transmits the revocation confirmation signal.

The screen is controlled as shown in (c) according to the control signal received from the opposite terminal. That is, the screen for the video call is simultaneously displayed on the digital multimedia broadcasting viewing screen and the video call screen. In this case, the screen layout may be set by the receiver or included in a control signal received from the counterpart terminal. As shown in (d), a part of the screen is displayed by receiving the same digital broadcast as the counterpart terminal, and the video call screen is reduced. Of course, as described above, in the case of a voice call using the ear microphone, the display may be displayed through the entire screen.

12 is an exemplary view of a screen according to another embodiment of the present invention. Similar to FIG. 11, there is a difference in that the driven application is driven by wireless Internet rather than digital multimedia broadcasting.

As in the displayed guide information, the video call is maintained but the same Internet web page is shared with the other terminal. That is, the UCC address viewed by the terminal A is transmitted with the control signal.

The screen is controlled as shown in (c) according to the control signal received from the opposite terminal. That is, the same UCC screen and the screen for the video call are simultaneously displayed. In this case, the screen layout may be set by the receiver or included in a control signal received from the opposite terminal. The configuration of the screen layout may be set by any one of two terminals, and an example for setting the screen layout is as shown in FIG. 13. As shown in (d), a part of the screen is displayed with the same UCC screen as the counterpart terminal, and the video call screen is reduced. Of course, as described above, in the case of a voice call using the ear microphone, the display may be displayed through the entire screen.

14 is an exemplary diagram illustrating an embodiment of an interface to be shared with a counterpart terminal during application execution. There may be various processing methods for sharing an application. You can use the menu function during a video call or use a special function button provided separately. If the terminal has a touch screen screen, as illustrated in FIG. 14, a drag and drop method of selecting an address screen of the current UCC using a stylus or a finger and dragging it to a screen of a partner in a video call is also implemented. Can be.
