Prior to the description of the present invention, the terms or words used in the specification and claims described below should not be construed as being limited to the ordinary or dictionary meanings, and the inventors should consider their own invention in the best way. For the purpose of explanation, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention on the basis of the principle that it can be appropriately defined as the concept of term. Therefore, the embodiments described in the present specification and the configuration shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all of the technical idea of the present invention, and various equivalents may be substituted for them at the time of the present application. It should be understood that there may be water and variations.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this case, it should be noted that like elements are denoted by like reference numerals as much as possible. In addition, detailed descriptions of well-known functions and configurations that may blur the gist of the present invention will be omitted. For the same reason, some components in the accompanying drawings are exaggerated, omitted, or schematically illustrated, and the size of each component does not entirely reflect the actual size.

Referring to FIG. 1, a system according to an embodiment of the present invention includes a user device 100 and a service device 200.

Basically, the user device 100 and the service device 200 communicate with each other via the network 300. The network 300 is not necessarily limited thereto, but is preferably an IP-based network. IP-based networks can exemplify the Internet. Hereinafter, it is assumed that the network 300 is an IP-based network.

The service device 200 services the user device 100 with content executed in an application through a network. In particular, the service device 200 provides a service to the user device 100 in a streaming manner. Such a service may representatively provide a video player (application) and a video (content) to play the video content in the video player. In this case, an application such as a video player may be provided in advance, and a video, which is a content, may be provided by streaming. As used herein, the term "streaming service" may representatively provide a video in real time. However, the “streaming service” is not necessarily limited to a service in which data is transmitted from the service device 200 to the user device 100 without interruption. Data may be discontinuously generated by the user device 100 and the service device 200, or by the service device 200, and the service device 200 may generate data that is discontinuously generated. At this point, the user device 100 may provide the information to the user device 100 in real time. As such, according to an embodiment of the present invention, all services that provide data in real time are included in the category of "streaming service."

For example, assuming that the service device 200 is a game server serving an online game, the input for the user to play the game may be discontinuous, and the user device 100 may cause the user device 100 to display the service device (eg, the discontinuous input). The service device 200 may generate data in real time by an input transmitted to the device 200, and provide the data to the user device 100 in real time.

In another example, the service device 200 is a server that executes a text editor that is an application on the service device 200 in a cloud computing environment, and provides an interface of a text editor that is part of the application and a document that is content to be edited. Assume Even in this case, the input by the user through the interface of the text editor may be discontinuous, and the input of the user device 100 to the service device 200 by the discontinuous input causes the service device 200 to display the document in real time. The data generated by the editing may be provided to the user device 100 in real time.

Meanwhile, the user device 100 may be connected to the service device 200 through the network 300 to receive the various types of applications and contents described above and execute them on the user device 100. In this case, according to a user's request, the user device 100 may execute or terminate the application. When there is an input for requesting to terminate the application from the user, the user device 100 creates a termination message and transmits it to the service device 200. Then, the service device 200 stores only some of the data related to the service provided by the streaming method. Here, the stored some data may be data necessary for providing the streaming service as it is when the service device 200 terminates the service, that is, when the application is terminated. That is, the data may be required to execute the application and the content as it is when the application is terminated. Therefore, in the embodiment of the present invention, data that stores the state when the application is terminated (when the streaming service is terminated) is referred to as "state information."

Such state information may be state information according to the application itself. That is, the state information differs depending on the type of application stored state information. Alternatively, such state information may be state information according to content executed through a corresponding application. That is, the state information may be stored differently for each content.

For example, when the application is a game, the state information according to the application may be a setting for the size and resolution of the game screen, an interface setting, a shortcut key setting, and the like when the corresponding game is finished. In addition, when the state information according to the content is a role-playing game (RPG) game in which the application nurtures the character, the state information according to the content indicates the state (level, acquired item, or date and time of the character when the game ends). Location of the virtual space in the game at the time of interruption or termination, etc.). When the application is an adventure game that proceeds sequentially according to a series of events in the game, the state information according to the content may be the progress of the event when the corresponding game is finished. When the application is a recorded game that records a score as the game progresses, the state information according to the content may be a score obtained by the user when the corresponding game ends.

When the application is a video player, the state information according to the application may be a resolution of a screen when the video player is terminated, a type of subtitle language, a type of voice language, and the like. In addition, the status information according to the content may be a time stamp indicating the position where the video was played when the video was finished.

When the application is a text editor, the state information according to the application may be a setting for an interface of the text editor when the text editor is finished. For example, in the document editing interface, tools may be arranged, shortcut keys may be set. In addition, the state information according to the content may be a setting for the corresponding document when the corresponding text editor is finished. For example, it may be a letter shape, a paragraph shape, a font size, and the like of the document.

The above state information is preferably specified differently for each user. Even when using the same device, different settings can be made for each user. For example, when the application is an online game, and the status information according to the application is the setting of the size and resolution of the game screen, the interface setting, the shortcut key setting, etc., the screen size and resolution are each different. It should be set differently according to what you set.

In addition, the state information may be specified for each user device. For example, if the application is an online game, and the status information according to the application is the setting of the size and resolution of the game screen, the interface setting, the shortcut key setting, etc., the size and resolution of the screen is the user. There is a limit that can be set according to the unique characteristics of the device. That is, even if the same user is used, when the online game is accessed through another user device, the setting may vary depending on the device characteristics of the user device, that is, the screen size of the user device and the resolution supported. have. Therefore, according to the embodiment of the present invention, even if the state information for the same application of the same user can be stored according to the state information according to the user device.

Such state information may be stored only by some of the plurality of state information by the state information indicator. The status information indicator is for setting or indicating status information to be stored. This status information indicator may be set at any time before the termination of the application.

The status information indicator allows the user to directly set the status information to be stored. That is, the status information indicator indicates the status information to be stored set by the user. For example, if the status information for the application is screen size, resolution, interface, shortcut key, etc., when the user designates only the screen size, resolution, and interface as the status information to be stored, the service device 200 may indicate the status information indicator. According to the status information, the screen size, resolution and interface are stored as status information.

On the other hand, the status information indicator may indicate the priority of the status information to be stored. In this case, the service device 200 may calculate the allocated storage capacity or the extra storage capacity, and store the state information in the order of high priority according to the size of data that the calculated storage capacity can accommodate. For example, assuming that priority of status information to be stored through the status information indicator is designated in order of interface, shortcut, screen size, resolution, and the like, the storage capacity of the service device 200 is based on the priority and status information on the interface and shortcut. Assuming that only storage can be performed, the service device 200 may store only state information on an interface and a shortcut key according to the state information indicator.

As described above, after the service device 200 stores the state information, when the user device 100 re-executes the application, the user device 100 uses the stored state information to terminate the application in the service device 100. A request message for requesting to provide a service corresponding to the state of the service is generated and transmitted to the service device 200. The request message includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. Upon receiving the request message, the service device 200 provides a streaming service to the user device 100 according to the request message. That is, the service device 100 may provide a streaming service differently according to a user by referring to a user identifier of a request message, and if there is previously stored state information, the service device 100 may provide a streaming service according to the stored state information differently according to the user. The service device 100 provides a streaming service according to the user device by referring to the user device identifier of the request message. In particular, if there is previously stored state information, the service device 100 may provide a streaming service according to the stored state information according to the user device. The service device 100 provides a streaming service according to the application of the application identifier of the request message. In particular, if there is previously stored state information, the service device 100 may provide a streaming service according to the stored state information according to an application. The service device 100 provides a streaming service in which the content identifier of the request message differs depending on the content. In particular, if there is previously stored state information, the service device 100 may provide a streaming service according to the stored state information depending on the content.

As such, according to an embodiment of the present invention, only some data is stored when an application provided by the streaming method is terminated, thereby not storing an unnecessary large amount of data. The storage space can be saved efficiently. In addition, when an application is terminated, only some data is stored so that the application can be executed again according to the type of the application, the content of the application, the user, or the user device. When re-executing, while providing a quick response to the user's request, it can be provided without the need to re-set the settings according to the user's preferences.

Referring to FIG. 2, a service device according to an embodiment of the present invention includes a communication module 210, a storage module 220, an authentication module 230, and a control module 230.

The communication module 210 transmits and receives data with the user device 100 through the network 300. In particular, the device 100 is configured to transmit data such as an application or content to the user device 100 and receive a request message, an end message, and the like. In this case, the communication module 210 may transmit data in a streaming manner. That is, the communication module 210 receives data such as an application or content from the control module 230 and provides the corresponding data to the user device 100 in real time. The communication module 110 may further include a function of processing data according to the type of the network 300 and the protocol applied to the network 300.

The storage module 220 basically stores an application and content, and stores identification information and state information mapped to the identification information. The storage form of the storage module 140 may be stored according to a file system or may be stored according to a database system.

The control module 230 is basically for providing an application and content executed in the application to the user device 100 in a streaming manner. When the control module 230 receives the request message requesting to provide a service corresponding to the state at the end of the application from the user device 100 through the communication module 210, the control module 230 corresponds to the application identifier and the content identifier of the request message. The application and the content are extracted from the storage module 220. Then, the control module 230 transmits at least one of an application and content executed in the application to the user device 100 through the communication module 210 in a streaming manner. In this case, when there is prestored state information, the control module 230 may service an application and content corresponding to the application identifier and the content identifier of the request message to the user device 100 through the communication module 210 in a streaming manner. have. In addition, the control module 230 may service an application and content to the user device 100 through the communication module 210 in a streaming manner according to the state information corresponding to the user identifier or the user device identifier.

In addition, upon receiving the termination message from the user device 100 through the communication module 210, the control module 230 may store state information according to at least one of the user identifier and the user device identifier of the termination message. In addition, the control module 230 may store state information according to at least one of an application identifier and a content identifier. The control module 230 may store state information according to the state information indicator.

Referring to FIG. 3, the user device 100 according to an embodiment of the present invention includes a communication unit 110, a display unit 120, an input unit 130, a storage unit 140, and a controller 150.

The communication unit 110 may transmit a request message for requesting an application, content, or the like to the service device 200 under the control of the controller 150. In addition, the communication unit 110 may receive an application and content from the service device 200. At this time, the communication unit 110 receives an application according to a streaming technique. The communication unit 110 may further include a function of processing data according to the type of the network 300 and the protocol applied to the network 300.

The display unit 120 is a means for outputting information generated according to the use of the user device 100 so that the user can visually recognize it. The display unit 120 may be a touch screen. When the display unit 120 is formed in the form of a touch screen, the display unit 120 may perform some or all of the functions of the input unit 130. have.

The input unit 130 is a means for receiving at least one of a user's command, selection, data, and information, and may include a plurality of input keys and function keys for receiving numeric or text information and setting various functions. The input unit 130 detects a user's key input and transmits an input signal according to the detected key input to the controller 150. The input unit 130 may illustrate an input device such as a keyboard, a keypad, a mouse, a joystick, and the like. In particular, when the display unit 120 is formed in the form of a touch screen, some or all of the functions of the input unit 130 may be performed through the display unit 120.

The storage unit 140 is a device for storing data, and includes a main memory device and an auxiliary memory device. The storage unit 140 may store an operating system (OS), an application, and the like. In particular, the storage 140 may store state information according to an embodiment of the present invention. In addition, the storage 140 may store various types of data generated according to the use of the user device 100. Various data stored in the storage 140 may be deleted, changed, or added according to a user's manipulation.

The controller 150 may be a process device that actually runs an operating system. For example, the controller 150 may be a central processing unit (CPU). When the user device 100 is powered on, the controller 150 moves the operating system from the auxiliary storage device of the storage unit 140 to the main memory device, and then boots the operating system. In addition, when there is a request through the user's input unit 130, according to an embodiment of the present invention, a request message for requesting an application and content is generated, and the generated request message is transmitted through the communication unit 110. In addition, when there is a request through the input unit 130 of the user, an end message for terminating the application and the content is generated, and the generated end message is transmitted through the communication unit 110.

The controller 150 detects an input requesting to execute a specific application of the user through the input unit 130, and generates a request message and transmits the generated request message to the service device 200 through the communication unit 110. Here, the request message includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. The user identifier of the request message is for requesting to provide a streaming service differently according to a user. In particular, if there is prestored state information, the user identifier is for requesting a streaming service according to state information stored differently according to a user. The user device identifier of the request message is for requesting that the streaming service is provided differently according to the user device. In particular, if there is previously stored state information, the user device identifier is for requesting the streaming service according to the stored state information according to the user device. The application identifier of the request message is for requesting that a streaming service is provided differently according to an application. In particular, if there is previously stored state information, the application message is for requesting a streaming service according to state information stored differently according to an application. The content identifier of the request message is for requesting to provide a streaming service differently depending on the content. In particular, if there is previously stored state information, the content identifier is for requesting a streaming service according to the state information stored differently according to the content.

In addition, the controller 150 receives a streaming service. That is, the controller 150 receives the application and the content through the communication unit 110 and executes the application and the content.

The controller 150 receives the application and the content executed in the application through the communication unit 110 in a streaming manner, and detects an input for terminating the corresponding application through the input unit 130 during execution. And a termination message is transmitted to the service apparatus 200 through the communication unit 110. The end message is a request for storing state information, which is information about a state of an application or content at the end of a service. This termination message, like the request mesh, includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. The end message also includes a status information indicator. The status information indicator is for setting or indicating status information to be stored. This status information indicator may be set at any time before the termination of the application. The user identifier of the termination message is for requesting to store the state information differently according to the user, and the user device identifier of the termination message is for requesting to store the state information differently according to the user device. The application identifier of the termination message is for requesting to store state information differently according to the application, and the content identifier of the termination message is for requesting to store state information differently depending on the content.

The status information indicator allows the user to directly set the status information to be stored. For example, if the status information for the application is screen size, resolution, interface, shortcut key, etc., when the user designates only the screen size, resolution, and interface as the status information to be stored, the service device 200 may indicate the status information indicator. According to the status information, the screen size, resolution and interface are stored as status information. Alternatively, the status information indicator may specify the priority of the status information to be stored. Then, the service device 200 may calculate the allocated storage capacity or the extra storage capacity and store the state information in the order of high priority according to the size of data that the calculated storage capacity can accommodate. For example, assuming that priority of status information to be stored through the status information indicator is designated in order of interface, shortcut, screen size, resolution, and the like, the storage capacity of the service device 200 is based on the priority and status information on the interface and shortcut. Assuming that only storage can be performed, the service device 200 may store only state information on an interface and a shortcut key according to the state information indicator.

Referring to FIG. 4, if there is an input for requesting a user to execute a specific application, the user device 100 detects this at step S400 and requests for a service of a streaming method for a specific application or specific content at step S405. Create a message. In operation S410, the user device 100 transmits a request message generated to the service device 200. The request message includes identification information. The identification information includes at least one of a user identifier for distinguishing a user from another user and a user device identifier for distinguishing a user device from another user device. The request message may further include at least one of an application identifier for distinguishing an application, which is a target of requesting execution, from another application, and a content identifier for distinguishing content executed in the application from other contents.

It is assumed that the request message transmitted in step S410 is a request message transmitted first for the corresponding application or content. The service device 200 receiving the request message extracts an application and content with reference to the request message received in step S415. That is, the service device 200 extracts an application and content corresponding to the application identifier and the content identifier of the request message.

Next, the service device 200 determines whether the state information corresponding to the user identifier or the user device identifier is stored in advance, and if so, provides the application and the content to the user device 100 according to the state information. do. However, since it is assumed that the request message of step S410 is first transmitted for the corresponding application or content, there is no pre-stored state information. Therefore, the service device 200 may provide an application and content executed in the corresponding application to the user device 100 in operation S420. These applications and content are serviced in a streaming manner.

The user device 100 executes the corresponding application and the content in step S425. During this execution, the user device 100 may detect a request to suspend or terminate the user's application in operation S430. Then, the user device 100 generates an end message requesting to terminate the corresponding application in step S435, and transmits the end message to the service device 200 in step S440. The termination message, like the request mesh, includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. The end message also includes a status information indicator. The status information indicator is for setting or indicating status information to be stored. This status information indicator may be set at any time before the termination of the application.

The status information indicator allows the user to directly set the status information to be stored. For example, if the status information for the application is screen size, resolution, interface, shortcut key, etc., when the user designates only the screen size, resolution, and interface as the status information to be stored, the service device 200 may indicate the status information indicator. According to the status information, the screen size, resolution and interface are stored as status information.

Alternatively, the status information indicator may specify the priority of the status information to be stored. Then, the service device 200 may calculate the allocated storage capacity or the extra storage capacity and store the state information in the order of high priority according to the size of data that the calculated storage capacity can accommodate. For example, assuming that priority of status information to be stored through the status information indicator is designated in order of interface, shortcut, screen size, resolution, and the like, the storage capacity of the service device 200 is based on the priority and status information on the interface and shortcut. Assuming that only storage can be performed, the service device 200 stores only state information on an interface and a shortcut key according to the state information indicator.

The service device 200 receiving the termination message stores the state information with reference to the termination message in operation S445. That is, the service device 200 stores the state information according to at least one of the application identifier and the content identifier of the termination message and the state information indicator, and maps and stores the state information to at least one of the user device identifier and the user identifier. In operation S450, the service device 200 terminates the service for the corresponding application for the user device 100 that has transmitted the termination message.

On the other hand, the user may input to request the user device 100 to execute a specific application or content. Then, the user device 100 detects such an input in step S455, and generates a request message for requesting a streaming service for the corresponding application or the corresponding content in step S460. Generate a request message. The request message includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. Next, the user device 100 transmits a request message in step S465. The service device 200 receiving the request message extracts an application and content with reference to the request message in step S470. That is, the service device 200 extracts an application and content corresponding to the application identifier and the content identifier of the request message.

In operation S475, the service device 200 provides the user device 100 with at least one of an application and content according to the user information or the status information corresponding to the user device identifier. This is provided as a streaming service. Then, the user device 100 executes the application and the content provided according to the state information in step S480.

Referring to FIG. 5, it is assumed that the user device 100 transmits a request message requesting to execute a specific application to the service device 200. Here, the request message includes at least one of a user identifier and a user device identifier as identification information, and at least one of an application identifier and a content identifier. Here, it is assumed that the request message is a request message that is first transmitted for the corresponding application or content.

When the control module 230 receives the request message through the communication module 210 in operation S500, the control module 230 extracts an application and content corresponding to the application identifier and the content identifier of the request message from the storage module 220 in operation S505.

Then, the control module 230 transmits at least one of the application and the content executed in the application to the user device 100 through the communication module 210 in step S510. That is, the control module 230 services these applications and content in a streaming manner. Accordingly, the user device 100 will execute the corresponding application and content.

In addition, the user device 100 may generate an end message for requesting to terminate the corresponding application in response to a request for terminating the user's application while executing the application, and transmit the end message to the service device 200. .

If the control module 230 receives the end message through the communication module 210 in step S515, the control module 230 proceeds to step S520. On the other hand, if the end message is not received, the control module 230 continues to perform step S510.

The end message, similar to the request message, includes at least one of a user identifier and a user device identifier, at least one of an application identifier and a content identifier, and a status information indicator. The status information indicator is for setting or indicating status information to be stored. This status information indicator may be set at any time before the termination of the application. The status information indicator allows the user to directly set the status information to be stored. Alternatively, the status information indicator may specify the priority of the status information to be stored. When receiving the termination message, the control module 230 stores state information with reference to the termination message in operation S520. That is, the service device 200 stores the state information according to at least one of the application identifier and the content identifier of the termination message and the state information indicator, and maps and stores the state information to at least one of the user device identifier and the user identifier. In addition, the control module 230 terminates the service for the corresponding application for the user device 100 that has transmitted the termination message in step S525, and the service device 200 switches to the standby mode in step S530.

On the other hand, the user may input to the user device 100 to run the application again. In this case, the user device 100 may detect an input for executing an application and generate a request message. As described above, the request message includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. In addition, the user device 100 may transmit the generated request message to the service device 200.

Accordingly, when the control module 230 of the service device 200 receives the request message through the communication module 210 in step S535, the control module 230 proceeds to step S540, and if the request message is not received, the standby mode of step S530. Keep it.

When the request message is received, the control module 230 extracts an application and content from the storage module 220 with reference to the request message in operation S540. That is, the control module 230 extracts an application and content corresponding to the application identifier and the content identifier of the request message.

In operation S545, the control module 230 provides the user device 100 with at least one of the application and the content according to the state information corresponding to the user identifier or the user device identifier. This is provided as a streaming service. Then, the user device 100 will execute the application and the content provided according to the state information.

The controller 150 assumes the standby mode in step S610. In this standby mode, if there is an input for requesting a user to execute a specific application, the controller 150 detects such a request through the input unit 130 in step S615 and generates a request message requesting a specific application in step S620. do. The request message includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. Subsequently, the controller 150 transmits the request message to the service device 200 through the communication unit 110 in step S625.

The user identifier of the request message is for requesting to provide a streaming service differently according to a user. In particular, if there is prestored state information, the user identifier is for requesting a streaming service according to state information differently set according to a user.

The user device identifier of the request message is for requesting to provide a streaming service differently according to the user device. In particular, if there is previously stored state information, the user device identifier is for requesting a streaming service according to state information differently set according to the user device.

The application identifier of the request message is for requesting to provide a streaming service differently according to an application. In particular, if there is previously stored state information, the application message is for requesting a streaming service according to state information differently set according to an application.

The content identifier of the request message is for requesting that the streaming service is provided differently according to the content. In particular, if there is prestored state information, the content identifier is for requesting the streaming service according to the state information differently set according to the content.

Accordingly, the service device 200 provides the application and the content executed in the application, and if there is the state information stored in advance, the service device 200 will provide the application and the content according to the state information.

Then, the controller 150 receives the application and the content through the communication unit 110 in step S630, and executes the application and the content in step S635. These steps S630 and S635 are provided with a streaming service and are sequentially performed before the application is terminated.

During this execution, the user may make an input for terminating the application. Then, the controller 150 may detect this through the input unit 130 in step S640. Accordingly, the controller 150 generates an end message in step S645, and transmits an end message in step S650.

The termination message, like the request mesh, includes at least one of a user identifier and a user device identifier, and at least one of an application identifier and a content identifier. The end message also includes a status information indicator. The status information indicator is for setting or indicating status information to be stored. This status information indicator may be set at any time before the termination of the application.

The user identifier of the termination message is for requesting to store the state information differently according to the user, and the user device identifier of the termination message is for requesting to store the state information differently according to the user device.

The application identifier of the termination message is for requesting to store state information differently according to the application, and the content identifier of the termination message is for requesting to store state information differently depending on the content.

The status information indicator allows the user to directly set the status information to be stored. Alternatively, the status information indicator may specify the priority of the status information to be stored. Then, the service device 200 may calculate the allocated storage capacity or the extra storage capacity and store the state information in the order of high priority according to the size of data that the calculated storage capacity can accommodate.

The service device 200 receiving the end message will store state information with reference to the end message. That is, the service device 200 may store state information according to at least one of the application identifier and the content identifier of the termination message and according to the state information indicator, and map the state information to at least one of the user device identifier and the user identifier. The service device 200 will terminate the service for the corresponding application for the user device 100 that has transmitted the termination message.

On the other hand, after transmitting the termination message, the controller 150 may proceed to step S610 again to maintain the standby mode.

The above-described steps of FIG. 6 are repeated until the power supply of the user device 100 is terminated.

The present invention relates to an apparatus for storing data in a streaming service and a method therefor. The present invention provides a service in which a service device provides an application and content executed in an application to a user device in a streaming manner. Upon receiving the termination message requesting the termination of the service from the user device, the storage module stores the state information, which is information about the state upon termination, in the storage module. In addition, upon receiving the request message requesting to resume the service, the service device provides the user device with a service corresponding to the state at the end according to the stored state information. As described above, the present invention stores only some data necessary for executing the application as it is at the end of the application when the application is executed, depending on the application, the type of content, the user, or the device characteristics of the user device. By not storing unnecessarily large amounts of data, you can effectively save storage space. In addition, when the service providing the application and the content in the streaming method is terminated, the state may be stored, and when the service is provided again, the service may be provided as it is when the service is terminated. Accordingly, when the application is executed again, it is possible to provide a fast response speed to the user's request, and there is an advantage that it can be executed again as it was before the execution again. As such, the present invention can provide a user experience (UX, User eXperience) with increased convenience. This has industrial applicability because it is not only sufficient marketable or business possibility, but also practically evident.
