Description

{Method for controlling the multimedia contents of mobile phone}

The present invention relates to a method for controlling multimedia contents of a mobile communication terminal. More specifically, when a network Java game is played out of multimedia contents in a terminal equipped with a Java engine, an abnormal operation is abnormally occurred when a flip or folder of the terminal is closed. The present invention relates to a method of controlling multimedia contents of a mobile communication terminal for maintaining an operation of a program being executed by using a suspend / resume function of a Java program.

In general, game systems and game operating methods using wireless communication / mobile communication terminals have been increasing day by day with the success of multi-user games on the wired Internet, and the characteristics of the wireless Internet.

In particular, since network games are connected to a large number of users and play games, unlike a general arcade game against a computer, the unrealized life of unspecified users in different environments can be projected and enjoyed through free imagination. You can, through this endless possibilities and fun.

To this end, network games have a database of game status, user information, and quest progress of multiple users.

In particular, wireless network games are being developed with multi-wireless Internet games that support WAP or Microsoft's Mobile Explorer (WAP), a standard technology of WAP (Wireless Application Protocol) forums led by Ericsson, Phone.com, and Nokia. have.

In addition, the conventional mobile games are game virtual machines or script-based games. When executing a Java-based virtual machine game program and closing the flip or folder of the terminal, the terminal stops all the running programs. Enter the standby state.

If the terminal user is playing a Java game on the network or storing the Java game as a terminal, if the user accidentally or intentionally closes the flip or folder of the terminal abnormally, the game is being downloaded as well as the game that was being downloaded. Are all supposed to be stopped.

In other words, if an event occurs in which the flip or folder of the terminal is closed while the Java game is in progress, if the current virtual machine is in operation, all the playing programs are stopped.

Regardless of what state the network is in, virtual machine stops game events, suspends all in-progress modes, then puts the terminal in idle state and stops all Java engines, allowing the terminal user to properly prepare for it. Serious problems arise.

Therefore, the present invention has been proposed to solve the above-mentioned problems. When the network Java game of the multimedia content is played in the terminal equipped with the Java engine, the abnormal operation stops when the flip or the folder of the terminal is abnormally closed. It is an object of the present invention to provide a method for controlling multimedia contents of a mobile communication terminal for maintaining an operation of a running program by using a suspend / resume function of a Java program.

In order to achieve the above object, the present invention provides a method of controlling multimedia content in response to a flip or a folder opening / closing event of a mobile communication terminal. The first step of pausing the network and sending a pause event to the virtual machine if it occurs, and if the first step is processed, pauses the sound of the currently playing player, generates an alert event and then displays it on the user interface. A second step and a third step of displaying a pop-up screen when the second step is processed and the event of flipping the terminal or opening the folder again occurs, and reactivating all the suspended events from the paused time point again. It is made, including.

When the network is suspended, the connection state is physically disconnected at the network layer layer, but the connection state is maintained logically.

When the pause event is transmitted to the virtual machine, the data of all the events being executed according to the pause holding command is maintained without disappearing, and when the next resume command comes in, the resumed portion is resumed. Start the run.

The alert event delivers the event to the AMS or virtual machine, and the user interface display displays a specific icon on the sub (external) LCD display of the terminal to indicate to the user that the virtual machine is alive.

The pop-up screen gives the user the option to select whether to continue playing the Java game or return to the standby screen of the terminal by selecting a pop-up option.

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

1 is a block diagram showing the internal operation of a terminal equipped with a Java engine capable of a virtual machine Java game to which the present invention is applied.

Referring to FIG. 1, the controller 100 controls an overall operation of a mobile communication terminal 150 equipped with a Java engine to perform a voice call or various multimedia and virtual machine Java game functions.

In addition, if there is a game mode request from the user to implement a virtual machine Java game, the codec 102 controls the codec 102 to decompress and decode game program data downloaded from an external network, and then decodes the video program. The input still image or moving image data is encoded and then compressed into a predetermined format of JPEG / MPEG and controlled to be transmitted and received to an external network.

The memory 108 stores a predetermined program for controlling the operation of the virtual machine Java game of the terminal and a downloaded game program, and a predetermined area for data input / output when the overall operation of the terminal is performed by the controller 100. Store in

The RF (Radio Frequency) unit 110 refers to a comprehensive configuration of the high frequency processing unit, the intermediate frequency processing unit and the baseband processing unit, and wirelessly through an external network as well as voice and various virtual machine Java game data received through the antenna ANT. The received still image or game data is first processed at a wireless communication band frequency, and the intermediate frequency processing is lowered back to a low frequency band, and this is processed as a signal of a frequency band that can be processed by the controller 100 again.

In addition, various still images or video data inputted from the image input unit 104 provided in the terminal and encoded and compressed by the codec unit 102 are modulated into wireless communication band frequency signals and wirelessly transmitted to an external network.

The audio unit 112 modulates the voice signal input through the microphone MIC into a wireless signal under the control of the control unit 100, and demodulates the wireless game sound signal received through the RF unit 110. ) As an audio signal.

In addition, in the video call mode, the wireless audio signal included in the still image or video data received from the RF unit 110 is demodulated and reproduced through a speaker SPK.

The key input unit 114 includes a plurality of function keys including a plurality of numeric keys and a game mode key implemented to set a game mode for a game service on a terminal, and corresponding key data when a user presses a predetermined key. Is generated and output to the control unit 100.

The first display unit 116 is a sub screen of the terminal, which is configured on the outside of the terminal, and includes a liquid crystal display (LCD) for displaying various information of the terminal in a normal call mode, and a key generated from the key input unit 114. Data and various information signals of the controller 100 are received and displayed.

The second display unit 118 displays a still image or game data received from an external network in the game mode and a still image or game data input from an external device through the short-range wired / wireless transceiver 120 in the main mode of the terminal in color. .

The video input unit 104 is for a video call service. The video input unit 104 inputs the user's image or various still images and video images of the calling terminal user as image data to the codec unit 102 in the video call mode.

The codec unit 102 converts a captured image signal provided from the image input unit 104 into a JPEG or MPEG format under the control of the control unit 100 and compresses it at a predetermined rate, and receives still images or game data wirelessly received from an external network. Decompresses and decodes the compressed image to be output to the second display unit 118.

Game data wirelessly received from the external network may be game data downloaded from a multimedia game server, and may be web servers or a plurality of video content servers connected to a mobile switching center (not shown). It may be various VOD / AOD (Video / Audio On Demand) data provided from (Image Contents Servers).

The terminal cover detecting unit 120 detects an event in which the terminal user flips or opens or closes a folder cover of the terminal, either consciously or unconsciously, and transmits the event to the control unit 100.

When the flip or folder cover of the terminal is abnormally closed, the control unit 100 controls the game event or the download being executed on the virtual machine of the Java engine as a suspend holding command, which is a pause command, without controlling the downloading command. .

In the stop command, all of the running events are stopped and all of the corresponding data are lost. However, the suspend holding command, which is the pause command, is resumed next in the state in which the data of all the running events are held without disappearing. When the command comes in, execution resumes from the paused portion.

2 is a flowchart illustrating an overall operation flow according to a method of controlling multimedia contents in a mobile communication terminal according to an embodiment of the present invention. When the operation is started, the terminal 150 equipped with the Java engine is in a normal operation 201 state. After all the downloads 202 that receive various multimedia contents (game contents in the embodiment of the present invention) through the antenna ANT and the RF unit 110 are completed, the corresponding game is executed according to the terminal user's selection. (203).

In this case, the download 202 may be executed, but if a previously downloaded game is stored in the memory 108, the game may be selected and executed.

The terminal 150 on which the Java engine is mounted is only an embodiment of the present invention, and terminals in which all engines, such as a 3D engine, are selectively mounted in addition to the Java engine, are all included in the technical scope of the present invention.

The terminal 150 determines whether the terminal 150 is opened or closed during the download 202 or game execution 203, and whether the terminal 150 is opened or closed (204). If the cover of the terminal is abnormally closed, the currently downloaded network is temporarily suspended. It is suspended (205).

The network can be divided into several layer layers, whether Java or browser, and the network currently used in Java is largely a point-to-point protocol (PPP) layer and a specific service on a specific node of a connected communication network. It is divided into a socket layer (socket layer) that is an identifier for identifying each, can be divided into open (open), connected {connected (send / recv data state)}, closed (close state) for each layer.

Each layer and each state supports a dormant function, which is connected to the content server by a session and only ppp is suspended (205). .

That is, when the network connection state is physically disconnected but logically connected, and the terminal user unknowingly closes the flip or the folder of the terminal, the virtual machine (VM) If the event corresponding to the doment process is sent to the end, the doment process is performed and the cover of the terminal is closed.

In addition, the terminal user attempts to reconnect when the terminal user flips or reopens the folder.

The network can receive calls even when in a dormant state and can handle various messages and alert events.

The suspend event is sent 206 to the virtual machine with the network temporarily suspended 205.

The suspend event is controlled by a suspending holding command (207), which is a pause command without controlling a game event or a download being executed in a virtual machine of a Java engine when a flip or folder cover of a terminal is abnormally closed. do.

In the stop command, all of the running events are stopped and all of the corresponding data are lost. However, the suspend holding command 207, which is the pause command, is held in the state in which the data of all the running events are held without disappearing. When the resume command is received, execution resumes from the paused portion.

In other words, the virtual machine engine holds (207) all events and interpreters, a sub-processor that executes a Java program, a timer, and a timer, and when a virtual machine resume event is received. Wait until

When a suspend event is transmitted 206 to the virtual machine and the currently running events are held 207, the Java sound of the Java engine is paused 208.

When the cover closing event of the terminal is generated when the sound is currently used in Java, the Java sound forcibly transmits the closing cover event of the terminal to the sound interface and suspends the player currently in progress.

When the cover opening event of the terminal occurs, the suspended Java sound is resumed.

Pause 208 the Java sound and then generate an alert event 209.

The alert event generation 209 is a virtual machine is not dead in the standby state of the terminal when the cover closing event of the terminal during the Java progress, the alert event to the AMS (access method services) or virtual machine Deliver the event.

When the cover closing event of the terminal occurs, conventionally, a routine to process in the standby state of the terminal when receiving various events (sms), schedule (schedule), low battery (etc. In the present invention, since the virtual machine is not currently dead in the standby state of the terminal, the alert event is delivered to the AMS (access method services) or the virtual machine.

As described above, the present invention does not handle the existing case, so even if a cover closing event of the terminal occurs in the suspended state of the virtual machine, all alert events are processed in the standby state of the terminal and cannot be delivered to the virtual machine. do.

The alert event processing is performed according to a method supported by the UI structure of the corresponding terminal model.

In the state where the alert event has occurred 209, the user interface display 210 normally has no indication on the sub (external) LCD display of the terminal when the virtual machine is normal.

However, when the virtual machine is alive, a specific icon is displayed on the sub (external) LCD display of the terminal to indicate to the user that the virtual machine is alive.

In addition, when the reopening event occurs, the terminal cover may determine whether the event of reopening has occurred (211), and if the user continues to perform Java or return to the standby screen, a popup screen 212 may be displayed to the user. Provide options.

The pop-up option selection gives the terminal user the choice to continue playing the Java game or return to the standby screen of the terminal.

Therefore, regardless of the state of the terminal internally when the terminal user is running Java, all the execution of Java is suspended while the terminal cover closing event occurs and the terminal cover is reopened when the event of reopening the terminal occurs. This can be understood as the phenomenon of resumption (213).

Therefore, the operation of the terminal can be seen that the game or Java that was previously performed is continuously executed when the cover closing event of the terminal occurs and the terminal cover is reopened during the Java execution.

As described in detail above, the present invention uses the suspend / resume function of the Java program to stop abnormally when the terminal is abnormally closed when the network Java game is played in the multimedia content. By maintaining the operation of the running program, it provides a useful effect to preserve the program data of previously downloaded or running content without losing.
