Then, the runtime module 311 controls the generated renderer to render any page of the web application 200 and display the rendered result on the generated window. The runtime module 311 may receive an instruction to terminate the browser or an instruction to extinguish the window. In this case, the runtime module 311 retrieves the renderer and window resources of the browser engine module 313, and then terminates the web application 200 or extinguishes the window. In addition, the runtime module 311 terminates the corresponding web application 200 when all the windows in which the web application 200 is running have disappeared.

In addition, the runtime module 311 processes events that occur when the web application 200 is executed.

The runtime module 311 manages the life cycle of the web application 200 and the windows and pages of the web application 200. [ The web application 200 may be composed of a plurality of pages. In addition, at least one page is displayed through a window by starting at least one window for each web application 200. If you navigate to another page, the previous page may disappear. Also, when all the windows related to the web application 200 are closed, the web application 200 is terminated. As described above, there is a life cycle of the web application 200, the window and the page of the web application 200, and the runtime module 311 manages the life cycle.

In particular, the runtime module 311 stores the links of pages that have already been opened according to the order in which they were executed when a plurality of pages were executed, and stores the forward and backward page lists accordingly. The forward and backward page lists may be transmitted to other terminals as status information.

The runtime module 311 manages the registry. The registry takes up a part of the area of the storage unit 140, and the runtime module 311 stores a specific value in this registry and loads it if necessary. In particular, when the script language of the web application 200 is executed, the runtime module 311 stores the file type and various parameters according to script execution of the script language in the registry. In addition, the runtime module 311 is a function targeting the web application 200. When the web application 200 is installed, deleted, or updated, the runtime module 311 stores the information in the registry.

The browser engine module 313 interprets the web application 200 and displays it on the screen through rendering. To this end, the browser engine module 313 includes a browser engine for processing a markup language and a style sheet, and a script engine, which is an interpreter for processing a scripting language.

The browser engine module 313 also includes a protocol processor, an XML processor, a window processor, a font processor, an image decoder processor, an internationalization processor, and a system processor.

The protocol handler provides HTTP and HTTPS protocol functions and provides management functions such as uploads, proxies, and cookies required for HTTP function operations. The XML processor provides XML parser functionality and Extensible Style Sheet Language Transformations (XSLT) transformation. The window handler provides a window system to be used by the browser engine module 313, and provides UIs such as a button, a list box, a combo box, and a text editor to be used by the browser engine as components. It is called a UI component that a UI is provided as a component. Each operating system 400 may have its own window system and UI components. According to the embodiment of the present invention, when the status information of the web application 200 is transmitted to another terminal, the value of the UI component can be transmitted as the status information. The font processor provides a font system to be used by the browser engine.

The image decoder handler provides an image decoder function to be used by the browser engine. The internationalization processor provides the string conversion function necessary for multilingual processing. The system handler provides system functions such as a timer.

The protocol processor, the XML processor, the window processor, the font processor, the image decoder processor, the internationalization processor, and the system processor may be implemented as a function of the web application , And may request the operating system to perform a corresponding function through the porting layer 320.

The authentication module 315 performs authentication when transmitting, receiving, installing, and executing the web application 200. Here, authentication is a procedure for confirming whether or not the web application 200 is transmitted, received, installed and executed by a proper procedure. For this authentication, the authentication module 315 has a hashing algorithm and various security libraries, and performs an authentication function accordingly. Next, the transplantation layer 320 according to the embodiment of the present invention will be described.

The porting layer 320 provides an interface by the execution layer 310 so that the web application 200 can be implemented and operated independently of the type of the operating system 400. To this end, the interface of the transport layer 320 is implemented according to the type of the operating system 400 transplanted into the terminal. Accordingly, when the web application 200 requests the execution layer unit 310 to execute the function, the execution layer unit 310 can deliver the function to the transplantation layer unit 320. The porting layer 320 may instruct the operating system 400 to execute a corresponding function through the function execution request received from the execution layer 310.

The porting layer 320 includes a plurality of interface modules, and each interface module includes a plurality of interfaces that are related to each other by functions. Each interface is for requesting the operating system 400 to execute the functions of the terminal according to the type of the operating system 400.

The interfaces of the interface module can be implemented and managed in the form of a library, respectively. If you want to provide additional interfaces to execute additional functions, you can define a separate interface, implement it as a library, and link it to the corresponding interface module. Such an interface may be implemented to execute the corresponding function through the operating system 400 according to the type of the operating system 400 or may be implemented by converting only the format of the request of the web application 200 according to the operating system 400 Or may be a stub that bypasses system 400.

Syntax that can be interpreted by the first operating system 401 is referred to as a first syntax, and syntax that can be interpreted by the second operating system 402 is referred to as a second syntax I suppose. It is also assumed that the syntax provided by the library of the interface module of the porting layer unit 320 for performing the specific function is the third syntax. According to an embodiment of the present invention, the source file 210 of the web application 200 is created according to the third syntax.

When the web application is executed in the first terminal 101 in which the first operating system 401 is implanted and the third syntax is executed, the interface module performs a function of the first operating system 401, To a first syntax that can be interpreted by the first processor 401, and provides it to the operating system. Accordingly, the first operating system 401 can perform the corresponding function.

When the web application 200 is executed in the second terminal 102 to which the second operating system 402 is implanted and the third syntax is executed, 2 operating system 402 to a second syntax that the operating system 402 can interpret and provides to the second operating system 401. [ Accordingly, the first operating system 401 can perform the corresponding function.

Accordingly, the first and second terminals 101 and 102 having different operating systems 400 can execute the web application 200 in the same manner.

As described above, the interface module provides a syntax for performing a specific function for each type of the function. That is, the interface module includes a module that performs a hypertext transfer protocol (HTTP) related function, a module that performs XML (eXtensible Markup Language) related functions, a module that performs a thread related function, a module that performs a UI related function, A module for performing storage related functions, a module for performing resource management, and the like. 6 is a flowchart illustrating a method of executing a web application by transmitting and receiving status information in different terminals according to an embodiment of the present invention.

Referring to FIG. 6, the first terminal 101 is executing the web application 200 in step S601. If the first terminal 101 detects a request to transmit the web application 200 from the first terminal 101 to the second terminal 102 in step S603, ) Is not installed, the corresponding web application 200 is transmitted. The second terminal 102 receiving the web application 200 installs the corresponding web application 200 in step S605.

If the same web application 200 exists or the same web application 200 is transmitted, the first terminal 101 transmits the status information of the web application 200, which is being executed in step S607, to the second terminal 102 send. The second terminal 102 receiving the status information executes the web application 200 according to the status information in step S609.

The status information is information on a state in which the web application 200 is currently executing and includes a page currently being executed, a registry value, a UI (User Interface) component value, and a forward / backward page list . By executing the web application 200 through the status information, the user can execute the web application 200 as it is running in various terminals.

7 is a diagram for explaining a method for providing an execution environment of the same web application in a terminal having different operating systems according to an embodiment of the present invention.

In FIG. 7, one of the pages 700 of the web application 200 is shown in FIG. Reference numeral a indicates a page 700 displayed on the window 710 in the first terminal 101 and reference numeral b indicates a page displayed on the window 710 in the second terminal 102 700). The page 700 is displayed on the window 710 and the UI component 720 is displayed on the page 700. Here, the UI component 720 illustratively shows an edit box 721 and a button 723.

The platform 300 according to the embodiment of the present invention may include a window 710 and a UI component 720 according to each operating system 400. In this case, ). ≪ / RTI > For this reason, the operating system 400 can execute the same web application in the first terminal 101 and the second terminal 102, which are different from each other. This will be described in more detail as follows.

When the first terminal 101 and the second terminal 102 execute the page 700 of the web application 200, the web application 200 calls and displays the window 710 on the platform 300, It requests the platform 300 to display the page 700 in the called window 710 and display the UI component 720 in the page 700. [ This is the same for both the first terminal 101 and the second terminal 102. In the case of the first terminal 101, the platform 300 displays the window 710 on the screen using the interface according to the first operating system 401, and the page 700 displayed on the window 710 The platform 300 requests the first operating system 401 to display the UI component 720 on the window 710 using the interface of the second operating system 402. In the case of the second terminal 102, To request the second operating system 402 to display the page 700 and to display the UI component 720 on the page 700 of that window 710.

For example, the syntax provided by the platform 300 to display the window 710 is assumed to be the third syntax "OpenWindows () ", and the web application 200 uses the third syntax It is written according to "OpenWindows ()". Accordingly, when the operating system 400 executes the web application 200 on the other first terminal 101 or the second terminal 102, the third syntax "Open.Windows ()" .

On the other hand, the syntax for calling the window 710 according to the first operating system 401 is assumed to be the first syntax "OPEN_WINDOWS () ", and the syntax for calling the window 710 according to the second operating system 401 is The second syntax is " Show.Windows () ".

Accordingly, in the case of the first terminal 101 in which the first operating system 401 is implanted, the platform 300 can determine whether or not the "Open " Windows () "to" OPEN_WINDOWS () ", and provides it to the first operating system 401. Accordingly, the first operating system 401 calls the window 710 and displays it on the screen.

In addition, in the case of the first terminal 102 to which the second operating system 402 has been implanted, the platform 300 may execute the "OpenWindows () " Open.Windows () "to" Show.Windows () ", and provides it to the first operating system 401, the first operating system 401 calls the window 701 to display it on the screen .

In the case of a call to window 710, the window system of each operating system 401, 402 is different, so the type of window 710 displayed depends on the operating system 401, 402. For example, by comparing reference numerals (a) and (b), it can be seen that the form of minimizing, maximizing, shortening, minimizing, maximizing, and closing buttons 711 is displayed differently. The platform 300 has an interface (third syntax) that calls the UI component 720 even in the case of the UI component 720 as in the case of the call of the window 710. The platform 300 includes the web application 200 (Third syntax) to call each UI component 720 to the UI component 720. When the web application 200 invokes the UI component 720 using this interface (third syntax), the platform 300 May change the interface (first syntax or second syntax) according to each operating system 400 to call the UI component 720 according to the operating system 400.

However, the form of the UI component 720 is displayed differently according to the respective operating systems 401 and 402 as shown in (a) and (b).

In addition, as described above, the platform 300 provides the interface performing the above-described role through the interface module of the transplantation layer 320, and the interface module performs functions related to hypertext transfer protocol (HTTP) Modules that perform XML (eXtensible Markup Language) related functions, modules that perform thread related functions, modules that perform UI related functions, modules that perform storage related functions, and perform resource management And provides an interface that performs the same function to the web application 200 regardless of the type of the operating system 400,

8 is a diagram for explaining status information of a web application transmitted and received according to an embodiment of the present invention.

The user sequentially executes the first, second, and third pages 810 of the web application 200 at the first terminal 101 to create the questionnaire described in the first and second pages 810 and 820 It is assumed that the second page 820 has been executed in order to correct the questionnaire of the second page 820 while preparing the questionnaire of the third page 830. [ At this time, it is assumed that the user inputs a request to the first terminal 101 to execute the web application 200 at the second terminal 102 in order to execute the web application 200 at the second terminal 102 do. The first terminal 101 transmits the same web application 200 when the same web application 200 does not exist in the second terminal 102. The first terminal 101 transmits status information when the second terminal 102 installs the web application 200 or when the same web application 200 as the first terminal 101 is already installed.

The status information includes a currently running page, a registry value, a UI (User Interface) component value, and a forward and backward page list.

The first terminal 101 transmits the identifier of the second page 820 to the second terminal 102 as a page identifier.

The first terminal 101 transmits to the second terminal 102 a file type and parameters of a script language currently being executed in the second page 820 as a registry value.

The first terminal 101 receives the value of the radio button 802 that checks that the questionnaire item asking gender is gender in the first page 810 and the value of the radio button 802 that checks the age of the question item asking age The value of the radio button 804 checked twice a month in the question item asking the frequency of using the store in the second page 820 and the value of the radio button 804 checked in the edit box of the third page 830 805, " Please extend the weekend discount time zone "to the second terminal 102.

Since the forward and backward page lists have been executed in the order of the first, second and third pages 810, 830 and 840, the first terminal 101 has the second page 820 ) Is the third page 830 and the backward page of the second page 820 is the first page 810 to the second terminal 102. [

The second terminal 102 receiving the above-described status information executes the second page 820. This method of execution is the same as that of the first terminal 101, as described above with reference to FIG. Also, the second terminal 102 links the third and first pages 830 and 810 to the forward and backward pages of the second page 820, respectively, and sends a radio button And the value of the text editor. The storage space for storing the file type and the parameter according to the type is allocated to the memory through the registry value according to the execution of the script language.

9 is a flowchart illustrating a method of transmitting status information of a terminal according to an embodiment of the present invention. In FIG. 9, a description will be given of a method of transmitting status information of the web application 200 of the first terminal 101 of FIG.

Referring to FIG. 9, the controller 170 is executing the web application 200 in step S901. As described above, the control unit 170 drives the platform 300 and executes the web application 200 through the platform 300. The web application 200 is executed as described above with reference to FIG. That is, the web application 200 requests the platform 300 to execute a specific function using the interface of the platform 300. The platform 300 then requests the first operating system 401 to perform the corresponding function using the interface according to the first operating system 401 of the first terminal 101, (401) performs the corresponding function.

At this time, it is assumed that the user requests the other terminal to execute the web application 200. In step S905, the controller 170 determines whether the web application 200 can be transmitted through one of the wireless communication unit 110, the wireless LAN communication unit 120, and the wireless fan communication unit 130 in step S905. And searches the terminal 100 to see if it exists in the vicinity. Then, the control unit 170 displays the identifier of the terminal 100 searched in step S907 through the display unit 150. [

The user can select the desired terminal 100 among the displayed terminals 100. When the user selects the terminal 100 to which the web application 200 is to be transmitted, the controller 170 senses the terminal 100 in step S909 and requests a connection to the terminal 100 in step S911. Here, it is assumed that the terminal 100 selected by the user is the second terminal 102. For this reason, the controller 170 determines whether the connection with the second terminal 102 is successful in step S913. If the connection is successful, the connection success message is received from the second terminal 102. If the connection is unsuccessful, the connection success message can not be received within the predetermined time.

If it is determined in step S913 that the connection success message is not received within a predetermined time, the controller 170 displays on the display unit 150 that the web application 200 can not be transmitted due to the connection failure in step S915, Terminate the process. On the other hand, if it is determined in step S913 that the connection is successful, the controller 170 determines whether the same web application 200 is already installed in the second terminal 102 in step S917. This can be confirmed by receiving a message requesting the web application 200 from the second terminal 102.

If it is determined in step S917 that the same web application 200 is not installed, the control unit 170 transmits the corresponding web application 200 in step S919. Accordingly, the second terminal 102 will install the received web application 200. On the other hand, if it is determined in step S917 that the same web application 200 is already installed, the controller 170 proceeds to step S921.

If the web application 200 is transmitted or the web application 200 is already installed in the second terminal 102, the controller 170 transmits status information of the web application 200 in step S921.

The status information is information on a state in which the web application 200 is currently executing, and includes a page identifier, a registry value, a UI (User Interface) component value, and a forward and backward page list.

For example, referring to FIG. 8, the first terminal 101 transmits an identifier of the second page 820 as a page identifier, and as the registry value, the type of the file of the script language currently being executed in the second page 820 Parameters and the like to the second terminal 102. Also, the first terminal 101 checks the value of the radio button 802 that checks that the questionnaire item asking gender is gender in the first page 810 and the 20 items of the survey item asking the age as the value of the UI component A value of a radio button 804 that is checked two times a month in the question item asking the frequency of using the store in the second page 820 and a value of the radio button 804 that is checked twice in a month, To the second terminal 102, the text "Please extend the weekend discount time zone" The first terminal 101 is a forward and backward page list and the forward page of the second page 820 is a third page 830 and the backward page of the second page 830 is a first page 810. [ And transmits information informing that it is.

As described above, a method for the second terminal 102 to execute the web application 200 using the status information when the first terminal 101 transmits status information will be described.

10 is a flowchart illustrating a transmission method for executing a web application according to an embodiment of the present invention.

In FIG. 10, a method of transmitting the web application 200 corresponding to the second terminal 102 of FIG. 6 will be described.

Referring to FIG. 10, the controller 170 receives a connection request from the first terminal 101 in step S1001. This connection request is a request for establishing a connection for receiving the web application 200 and status information.

The controller 170 determines whether the connection is possible in step S1003. If it is determined in step S1003 that the connection can not be established, the controller 170 transmits a connection failure message in step S1005 and terminates the process. On the other hand, if the connection is possible, the controller 170 transmits a connection success message indicating that the connection is successful in step S1007.

Then, the controller 170 determines whether the web application 200 based on the connection request received from the first terminal 101 exists in step S1009.

At this time, if the corresponding web application 200 does not exist, the controller 170 requests the corresponding web application 200 in step S1011, and receives and installs the web application 200 in step S1013. On the other hand, if the corresponding web application 200 exists, the controller 170 transmits a message indicating that the corresponding web application 200 is already installed in step S1015.

When the web application 200 is installed, the control unit 170 receives the status information in step S1017 and executes the web application 200 according to the status information received in step S1019.

8, the controller 170 receives the identifier of the second page 820 as the page identifier under execution, and transmits the identifier of the second page 820 ). At this time, the controller 170 causes the second page 820 to execute the second page 820 using the file type and parameters of the script language being executed.

For example, the control unit 170 may cause the platform 300 to execute a window for displaying the second page, using the interface provided by the platform 300, to execute the second page, This is the same as the first terminal 101. [ The platform 300 running in the control unit 170 of the second terminal 102 may request the second operating system 402 to execute a window using an interface of a format suitable for the second operating system 402 And thus, the operating system 402 executes the window. The control unit 170 then requests the platform 300 to display the UI component of the second page. Accordingly, the platform 300 requests the second operating system 402 to display the UI components. Accordingly, the second operating system 402 displays a radio button which is an UI component of the second page. 7, the control unit 170 determines, based on the received UI component value, the number of radio waves indicating two times a month in the question item asking the frequency of using the store of the second page 820, Button 804 is checked.

On the other hand, the control unit 170 determines the value of the radio button 802 that checked the gender in the first page 810, the value of the radio button 803 that checked the age of 20 in the question item asking age, And the text "Please increase the weekday discount time zone" entered in the edit box 805 of the third page 830 are stored, and the corresponding values are applied when the corresponding page is executed.

And the forward page of the second page 820 as the forward and backward page list is the third page 830 and the backward page of the second page 820 is the first page 810 If the user requests to execute a forward page or a backward page, respectively, the third page 830 and the first page 810 are executed.
