FIG. 1 is a configuration environment diagram of a web application service providing system to which a user apparatus 200 for web application management according to an embodiment of the present invention is applied.

A web server 100 connected to the user device 200 through a communication network to provide a web application to the user device 200 and a web application 100 providing web application related data And a cloud streaming server (CSS) that transmits data generated by executing web application-related data from the web server 100 to the user device 200 in a streaming manner, (300).

In this case, the user device 200 may be a set-top box (STB), or may be a smart phone, a portable terminal, a mobile terminal, A personal digital assistant (PDA), a portable multimedia player (PMP) terminal, a telematics terminal, a navigation terminal, a personal computer, a notebook computer, a slate PC, A tablet PC, an ultrabook, a wearable device (for example, a smartwatch, a glass-type terminal, a head mounted display, etc.), a Wibro ) Terminal, an IPTV (Internet Protocol Television) terminal, a smart TV, a digital broadcast terminal, an AVN (Audio Video Navigation) terminal, an A / V (Audio / Video) system, a flexible terminal, There All.

The web server 100, the cloud streaming server 300 and the user device 200 can communicate with each other through a wired / wireless communication network. Examples of the wireless communication network include a wireless LAN (WLAN), a DLNA Digital Living Network Alliance), Wireless Broadband (Wibro), World Interoperability for Microwave Access (Wimax), Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 , Enhanced Voice-Data Optimized or Enhanced Voice-Only (EV-DO), Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), IEEE 802.16, Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE), Wireless Mobile Broadband Service (WMBS), Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association IrDA), UWB (Ultra Wideband), ZigBee, Near Field Communication (NFC), Ultra Sound Communication (USC), Visible Light Communication (VLC), Wi-Fi, Wi-Fi Direct, . The wired communication network may include a power line communication (PLC), a USB communication, an Ethernet, a serial communication, and an optical / coaxial cable.

In the above-described configuration, the user device 200 provides selection information for a web application to be accessed and executed by the web server 100 via a communication network, and the web server 100 may transmit the selection information to the user device 200, Can be extracted from the application DB and transmitted to the web browser of the user device 200. [

Accordingly, the user device 200 can execute the web application using the web application related data received from the web server 100 through the web browser.

At this time, the user device 200 requests an application profile for the web application selected by the user device 200 to the web server 100 when the web server 100 accesses the web server 100, Can be extracted from the application DB and transferred to the user device 200. [

Herein, the application profile includes resource occupation per the resource of the main processor (CPU), memory, graphics processor (GPU), and the HTML5 function necessary for driving the web application when the web application is executed And the like.

In addition, the application profile may include information for identifying that the offline web application is an offline web application that requires offline operation.

Meanwhile, the user device 200 can use available resources for a resource such as a main processor (CPU), a memory, a graphics processor (GPU), and the like configured in the user device 200, Information about available resources including functions and the like can be stored as a device profile.

Accordingly, the user device 200 compares the device profile or the current device availability information with the application profile to determine whether to use the web caching logic for the offline application operation through the application profile received from the web server 100, It is possible to determine whether to perform the web application through the cloud streaming server 300 or the web application service through the cloud streaming method through the cloud streaming server 300.

Thereafter, the user device 200 receives and executes the requested web application related data according to the selection information from the web server 100 according to the determination result, or transmits the web application related data from the cloud server 300 to the web server 100 And receives the generated result information from the cloud streaming server 300 in a real-time streaming manner to execute the web application through web virtualization.

2, the cloud streaming server 300 receives a request from the web server 100 from the user device 200 to the web server 100 through the web server 100, Receives the selected web application-related data, drives (executes) the web application program, and compresses the video information and audio information output in response to the driving of the web application in real time to generate the result information, live streaming) method.

At this time, the cloud streaming server 300 may encode H.264 to improve compression efficiency, but it is not limited thereto and various compression algorithms (codecs) can be applied.

Accordingly, the user apparatus 200 receives live-streaming result information, separates the video information from the audio information, and generates video information and audio information based on the video information and the synchronization information included in the audio information. And can be reproduced through the web browser of the user device 200 in synchronization.

At this time, the user apparatus 200 may decode the video information and the audio information according to a decoding scheme corresponding to the compression method of the video information and the audio information, and then output the video information and the audio information after the rendering process.

On the other hand, the user device 200 outputs real-time image information transmitted in real time in accordance with the driving of the web application on the screen in real time, and displays a touch input or key for operating the web application, Upon receipt of the input, user input information may be generated and transmitted to the cloud streaming server 300 in real time.

Accordingly, the cloud streaming server 300 may execute the functions related to the web application corresponding to the user input information, and then transmit the video information and the audio information of the execution result to the user device 200 in real time by the streaming method again .

As described above, the cloud streaming server 300 provides the result of the execution of the web application as an image, and when the user input information on the operation of the web application is received from the user device 200, And provides the result as an image in real time streaming, so that the web application can be virtualized and provided.

Accordingly, the present invention can provide a web application in the form of an online web application based on the cloud streaming server 300 when the available resources of the user device 200 do not satisfy the required resources required for executing the web application, It is possible to provide unlimited services such as a main processor, a graphic processor, a memory, and the like of the user device 200.

Meanwhile, in the above-described configuration, the user device 200 can manage various web applications that are serviced by the web server 100 by using the web caching logic, and the cache file (temporary file) 200). ≪ / RTI > In addition, the web application related data is transmitted to the user device 200 as a separate download logic through the web server 100 and is not installed.

The storage unit configured in the user device 200 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD Or XD memory), a magnetic disk, a magnetic disk, an optical disk, a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read- ), And a programmable read-only memory (PROM). In addition, the user device 200 may operate in association with web storage or operate web storage that performs the storage function of the storage unit 220 on the Internet.

Accordingly, when the user device 200 desires to receive a service previously received through the web browser, the web server 100 first accesses the cache file to execute the web application, If updated (updated), the latest web application will not be serviced.

In particular, in the case of a web application having a requirement to be driven even when it is not connected to the web server 100, the user device 200 is implemented as an offline web application defined by the World Wide Web Consortium (W3C) There is a problem in that the web application can not be maintained up to date by preferentially executing the cached file.

Meanwhile, when the user wishes to remove a web application which is no longer desired to receive a service, the cache file related to the web application to be removed must be directly found and removed. In case of neglecting the cache file, unnecessary data occupies the memory, The internal processing speed can be lowered. This degradation of memory efficiency causes degradation of the service quality of the web application service.

Accordingly, there is a need for a configuration for supporting efficient management of a web application that is serviced by the web server 100 in the user device 200.

At this time, the external arbitrary terminal may include a network service system, a server, and the like. The communication unit 230 may be a wireless LAN (WLAN), a Digital Living Network Alliance (DLNA), a Wireless Broadband (Wibro), a World Interoperability for Microwave Access (WIMAX) ), Code Division Multi Access (CDMA), Code Division Multiple Access (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA) , HSUPA (High Speed Uplink Packet Access), IEEE 802.16, Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), Wireless Mobile Broadband Service (WMBS) (Bluetooth), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Near Field Communication (NFC), Ultra Sound Communication USC), Visible Light Communication (VLC), WiFi (W i-Fi, and Wi-Fi Direct. The communication unit 230 may support wired communication methods such as power line communication (PLC), USB communication, Ethernet, serial communication, and optical / coaxial cable.

In addition, the storage unit 220 stores data and programs necessary for the user apparatus 200 to operate.

The storage unit 220 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, an SD or XD memory A random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a PROM (Programmable Read-Only Memory). In addition, the user device 200 may operate in association with web storage or operate web storage that performs the storage function of the storage unit 220 on the Internet.

Meanwhile, the control unit 210 executes the overall control function of the user device 200 by using the program and data stored in the storage unit 220. The control unit 210 may include a RAM, a ROM, a CPU, a GPU, and a bus, and the RAM, the ROM, the CPU, and the GPU may be connected to each other via a bus. The control unit 210 accesses the storage unit 220 and performs booting using an O / S (Operating System) stored in the storage unit 220. The control unit 210 may execute various programs stored in the storage unit 220, Various operations can be performed using data or the like.

The control unit 210 includes a device profile management unit 211, an application profile collection unit 212, a service control unit 213, an address acquisition unit 214, an address management unit 215, And a management unit 216.

At this time, each unit constituting the control unit 210 may be implemented by a hardware circuit (for example, a CMOS-based logic circuit), firmware, software, or a combination thereof. For example, it can be implemented utilizing transistors, logic gates, and electronic circuits in the form of various electrical structures.

In addition, each component of the user device 200 may be software stored on the memory of the user device 200. The memory may be an internal memory of the user device 200, and may be an external memory or other type of storage device. Further, the memory may be a non-volatile memory. The software stored on the memory may include a set of instructions that, when executed, cause the user device 200 to perform certain operations.

First, the device profile management unit 211 generates a device profile, which is information on available resources, with respect to an HTML5 function that can be supported by the main processor, the memory, the graphics processor, and the user device 200 configured in the user device 200, (220).

The application profile collecting unit 212 requests an application profile for the web application selected by the user device 200 when accessing the web server 100, receives the application profile from the web server 100, 213). ≪ / RTI >

The service control unit 213 determines whether to use the web caching logic for the offline web application operation through the application profile transmitted from the web server 100 through the corresponding application profile collection unit 212, The application profile may be compared to determine whether to perform a web application locally through the web browser or a web streaming service through the cloud streaming server 300. Based on the configuration shown in Fig. 3, .

As shown in the figure, the service control unit 213 loads the web browser and accesses the web server 100 through the communication unit 230, and transmits selection information for the web application to be executed to the web server 100 And receive the application profile for the web application corresponding to the selection information from the web server 100 through the application profile collection unit 212. [

Thereafter, the service control unit 213 compares the application profile and the device profile stored in the storage unit 220 to determine whether the available resource according to the device profile satisfies the requested resource according to the application profile (whether or not the available resource is the requested resource) It is possible to determine whether to perform a web application locally through the web browser or a web application service through the cloud streaming server 300 in a cloud streaming manner.

When the service control unit 213 executes the web application locally through the web browser according to the determination result, the service control unit 213 can receive the web application related data corresponding to the selection information from the web server 100 via the web browser and execute the web application .

At this time, the web server 100 can extract the web application-related data corresponding to the selection information from the application DB 101 and provide it to the user apparatus.

The service control unit 213 accesses the cloud streaming server 300 through the communication unit 230 if the web application is to be executed in a cloud streaming manner according to the determination result, and responds to the selection information from the cloud streaming server 300 It is possible to receive the result information provided in the real-time streaming according to the execution of the web application.

For example, if the service controller 213 does not satisfy the resource required to service the web application according to the resource availability state of the user device 200, Related data, captures video and audio according to execution, and accesses the cloud streaming server 300, which transmits the generated information to the user device 200 in a live streaming manner, 300 via the communication unit 230 in real-time streaming to execute the web application through the cloud streaming-based web virtualization.

At this time, the service control unit 213 generates output information according to the execution of the web application through the web browser and outputs the generated output information through the output unit 240, or outputs the result information provided in real time from the cloud streaming server 300 to the output unit 240).

Meanwhile, the device profile management unit 211 may generate device availability information, which is information on free resources that can be allocated to the web application among the available resources according to the driving state of the user device 200, and store the information in the storage unit 220.

At this time, the device availability information includes information on the availability of the main processor, the memory, the graphics processor, and the HTML5 function that can be supported for execution of the web application in the user device 200, And may include information on available resources that can be allocated to the web application.

At this time, the device profile management unit 211 may manage the device availability information separately from the device profile, store the device availability information in the storage unit 220, or replace the device profile with the device availability information.

Accordingly, when the device profile of the user device 200 satisfies the condition of the application profile, the service control unit 213 can compare the current device capability information of the user device 200 with the application profile.

Thereafter, when the current device availability information does not satisfy the application profile (when the free resource according to the device availability information is smaller than the requested resource according to the application profile), the service control unit 213 transmits the web application through the cloud streaming server 300 (When the available resources according to the device availability information are larger than the requested resources according to the application profile) in a real-time streaming manner and can be executed locally through a web browser.

On the other hand, when the web application is implemented as an offline web application as described in the above embodiment, the service control unit 213 can be executed as an offline web application based on the web caching logic.

The service control unit 213 can determine whether the web application to be executed is an offline web application to be executed offline by referring to the contents defined in the application profile.

For example, in the case of a web application requiring offline operation or requiring a concurrent service user rate (CSUR) equal to or higher than a predetermined reference value, the web server 100 may perform a web caching The application profile may further include information for identifying whether the application is offline or an offline application so that the web application can be executed even when the web server 100 can not access the web server 100 by using a cache file generated through the cache file .

Accordingly, the service control unit 213 can generate and store a cache file through web caching of web application-related data received from the web server 100 in the case of an offline web application by referring to the application profile.

At this time, the service control unit 213 may store the cache file generated through web caching in the storage unit 220 or the cache memory (buffer memory).

Thereafter, when the connection to the web server 100 is disconnected, the service control unit 213 can execute the web application in an off-line state using the cache file generated through web caching.

Through the above-described configuration, the user device 200 can easily and adaptively execute the web application based on the local browser or the cloud streaming server 300 using the device profile, the device availability information, and the application profile The application can be easily executed without restriction of software and hardware even for an application that can not be executed by the available resources of the user device 200. The application that can be executed locally can be executed locally Web application services can be provided.

In addition, the user device 200 can recognize the current operation status of the web application service, determine whether the web application can be executed with the free resource based on the current operation status, and determine the service type adaptively. And the communication load can be reduced.

In addition, the user device 200 adaptively divides an offline web application that requires offline execution even if the connection to the web server 100 is disconnected, and provides a web application so that the web application can be executed in an offline state through web caching Services can be sustained.

Meanwhile, in the above-described configuration, when the service control unit 213 accesses the web server 100 and executes the same application as the previously executed web application, the service control unit 213 accesses the cache file created and stored through web caching and executes the web application However, when the web application is executed only by the cache file, it is difficult to maintain the up-to-date web application. Accordingly, the web server 100 can not use various updated services for the corresponding web application.

Therefore, there is a need to manage the web application used by the user in order to maintain the up-to-date property. When the web application having low frequency of use is removed, the related cache file is deleted so that the resource capacity of the memory is secured, It is important to manage.

The configuration for this will be described with reference to FIG. 5 with reference to FIG.

The control unit 210 may include an address acquisition unit 214, an address management unit 215, and an update management unit 216 in addition to the above-described configuration.

First, when the service obtaining unit 214 accesses the web server 100 from the service control unit 213 and receives related data for executing the web application, the service obtaining unit 214 obtains the URL (Uniform Resource Locator) address from the web browser loaded by the service control unit 213. [

Accordingly, the address obtaining unit 214 can obtain the URL address related to the web application executed by the service control unit 213. [

Meanwhile, the address management unit 215 can receive the URL address acquired by the address acquisition unit 214 from the address acquisition unit 214, and can generate a URL list including the URL address.

At this time, the address management unit 215 has already generated the URL list, and if the web application executed by the service control unit 213 is not previously executed and the URL address does not exist in the URL list, It is possible to update the URL list by adding a URL address related to the web application executed by the web browser 213 to the URL list.

Accordingly, the address management unit 215 can generate a URL list by collecting the URL addresses obtained through the address acquisition unit 214 for each of various web applications executed by the service control unit 213, You can manage the web application you are using.

The service control unit 213 receives the web application related data and installs it in the user device 200. The cache control unit 213 generates a cache file through web caching when the web application is executed, Lt; / RTI >

The service control unit 213 executes the web application 100 using the cache file stored in the storage unit 220 without accessing the web server 100 when the currently executed web application is re- In the case of a web application defined as an offline web application that needs to be driven offline in an application profile received from the web server 100, the web application 100 is preferentially accessed using the cache file without connection even when connection to the web server 100 is possible.

As a result, even if the web server 100 updates the web application being executed in the user device 200, the service control unit 213 of the user device 200 executes the web application before the update, Will not be available.

Accordingly, the user device 200 according to the embodiment of the present invention supports the web application to keep the web application always up-to-date and to receive the updated service, which will be described in more detail with reference to FIG. 6 with reference to the above- do.

As shown in the figure, the update management unit 216 can acquire the URL address when executing the web application executed through the web browser loaded in the service control unit 213, and is included in the URL list in cooperation with the address management unit 215 The URL address of each web application to be executed can be compared with the URL address of the web application to be executed.

Accordingly, when the URL address matching the URL address of the web application executed by the service control unit 213 exists in the URL list, the update management unit 216 determines that the web application has been executed in the past, The service control unit 213 may provide a notification signal for updating in order to maintain the service state of the service control unit 213 in the latest state.

For example, as shown in the figure, when the URL address of the web application 1 executed by the service control unit 213 exists in the URL list, the update management unit 216 determines that the web application 1 has already been executed , And provides a notification signal for updating the service state of the web application 1 to the latest state to the service control unit 213.

Accordingly, the service control unit 213 can switch on-line to access the URL address for the web application 1 that is executed offline using the cache file upon reception of the notification signal from the update management unit 216.

Thereafter, the service control unit 213 accesses the Web server 100 according to the URL address of the web application 1, receives the latest update information related to the web application 1, and uses the update information to retrieve the existing web application related data The web application 1 can be executed with the updated web application related data updated or replaced. In this case, the update information may refer to data related to the updated web application 1, and it is needless to say that the service control unit 213 may execute the web application 1 only with the updated web application 1 related data.

In addition, the service control unit 213 generates an updated cache file through web caching when the updated web application 1 is executed, and replaces the cache file stored in the storage unit 220 with the updated cache file for the web application 1 Or updated.

Meanwhile, in the above-described configuration, the update management unit 216 may obtain the URL address through the address acquisition unit 214. [

If the URL address of the web application executed when the web application is executed by the service control unit 213 is included in the URL list as described above, the update management unit 216 accesses the URL address of the corresponding web application, The web application 100 can receive version information on the same web application as the web application currently being executed in the user device 200 and can receive the version information of the web application executed using the cache file stored in the storage unit 220 of the user device 200. [ Can be compared with each other.

Accordingly, the update management unit 216 updates the version according to the version information of the web application executed using the cache file by the service control unit 213 according to the version information of the web application provided in the web server 100 Version, it is possible to provide a notification signal for updating the currently executed web application to the service control unit 213 to update the service.

The update management unit 216 may not provide a notification signal when the version of the web application executed by the service control unit 213 is the same as the version of the web application provided by the web server 100. [

Through the above-described configuration, it is possible to manage a list of web applications executed in the past, so that whenever the same web application is executed again, the web application is managed to maintain the latest state, .

On the other hand, the service control unit 213 determines whether the currently executed web application is an offline application, based on the information for identifying whether the offline application included in the application profile provided from the application profile collection unit 212 is offline or an offline application, If the result is an offline web application, it can be executed using a cached cache file via web caching.

At this time, since the offline web application has a requirement to be operated even when the web server is not connected unlike the other web applications and is implemented as an off-line web application defined by W3C, the service control unit 213 Can execute the web application as it is through the web-cached cache file even if the offline web application is not accessible to the web server 100. [

Accordingly, even when the service control unit 213 receives the notification signal for the update from the update management unit 216, it is difficult to update the offline web application in the inaccessible state of the web server 100, Unlike other applications, the offline web application can be continuously executed only by the cache file. Therefore, the service in the pre-update state continues, and the service in the previous state continues even when the web server 100 is switched to a state in which connection is possible .

Accordingly, in order to update the service status of the offline web application in which the service continues even when the user apparatus 200 can not be connected to the web server 100, the update management unit 216 updates the application profile collection unit 212, And can determine whether the web application executed by the service control unit 213 is an offline web application based on the application profile.

The update management unit 216 can acquire the URL address of the offline web application through the address acquisition unit 214 and compare the URL address with the URL list. If the determination result of the web application executed through the service control unit 213 is negative In the case of a web application and a web application existing in the URL list, it is possible to determine whether or not the connection is possible by attempting to access the URL address of the offline web application periodically or in real time via the communication unit 230.

Thereafter, the update management unit 216 may provide a notification signal for the update to the service control unit 213 when the URL address of the offline web application is connectable.

That is, if the connection to the web server 100 is possible, the update management unit 216 provides an immediate notification signal to the service control unit 213. However, when the connection to the web server 100 is inaccessible, 100) is available, and can provide a notification signal to the service control unit 213.

At this time, the state in which the connection to the web server can not be established may include various factors such as a failure in the communication state of the user device 200 or the web server 100, a state in which only the connection to the URL address corresponding to the offline web application is impossible May be included.

Accordingly, when the notification signal is received during execution of the offline web application, the service control unit 213 determines that connection is possible with the URL address of the offline web application, connects to the URL address of the corresponding offline web application, From the web server 100, and update the offline web application related data using the updated information.

In addition, the service control unit 213 can generate a cache file through web caching when the offline web application updated with the update information is executed, and stores the cache file in the storage unit 220 as a new cache file corresponding to the updated offline web application It is possible to replace or update the existing cache file corresponding to the offline web application before the stored update.

At this time, the service control unit 213 outputs inquiry information about the progress of the update through the output unit 240 upon receipt of the notification signal, and responds to the inquiry information corresponding to the user input through the user interface unit 250 It can be determined based on the response information and connected to the web server 100 only in the case of the update progress, and the update to the offline web application that is being executed can be performed.

As described above, the user apparatus 200 according to the present invention can continuously connect to the URL address of the corresponding offline web application during execution of the offline web application that requires offline operation (execution) even when connection to the web server 100 is inaccessible And if the connection is possible, update can be performed during execution so that the service is kept up to date.

That is, the offline web application can be easily updated automatically even if the offline web application is requested to be offline, so that the service state of the offline web application can be kept up to date.

Accordingly, it is possible to maintain the latest state by updating each time when the user does not need to download the update information related to the web application separately, thereby improving the user satisfaction with the web application service and supporting the automatic update, thereby enhancing the user convenience .

Meanwhile, in the above-described configuration, the service control unit 213 may add only the web application that wants to maintain the user's up-to-date status to the URL list according to the user input through the user interface unit 250.

For example, the service control unit 213 determines whether to add the URL address of the corresponding web application to the URL list through the output unit 240 when executing the web application through the web browser according to the user input through the user interface unit 250 Can be output.

Accordingly, the service control unit 213 receives the response information corresponding to the user input through the user interface unit 250 in response to the inquiry information, and adds the currently executed web application to the URL list based on the response information The URL address of the currently executed web application is added to the URL list or the URL list including the URL address is generated through the address management unit 215 .

After that, the service control unit 213 can proceed to update through the web server 100 at the time of execution of the web application included in the URL list, as described above.

In addition, the service control unit 213 allows the cache file of the web application included in the URL list to be stored and managed in preference to the cache file of the web application not included in the URL list, It can be deleted after a lapse of time so that efficient management of a frequently used web application can be performed.

Meanwhile, the present invention can support a resource capacity of the user device 200 required for web application management by removing a web application that the user does not desire from the URL list, and at the same time, So that resources can be allocated to the execution of other web applications, thereby enhancing the internal processing speed of the user device 200 and improving the service quality thereof.

In addition, all the data stored in the user device 200 related to the web application can be deleted only by the deletion input, thereby enhancing the user's convenience. This will be described in more detail with reference to FIG. 7 based on the above-described configuration.

As shown in FIG. 7, the service control unit 213 receives a selection input for removal of a specific web application through the user interface unit 250, and removes the web application to be removed according to the selection input.

For example, the service control unit 213 may delete a URL address corresponding to a web application to be removed from the URL list managed through the address management unit 215 upon receiving a selection input for removal.

At this time, the address management unit 215 accesses the corresponding URL address when receiving the information on the URL address from the address acquisition unit 214, and receives the web application related identification information corresponding to the URL address from the web server 100, The URL list can be generated by matching the URL address and the identification information corresponding to the web application.

Accordingly, the service control unit 213 provides the URL list generated through the address management unit 215 through the output unit 240, receives the web application related identification information to be removed through the user interface unit 250, The URL address matching the corresponding identification information can be removed.

Also, the service control unit 213 can delete the cache file generated through web caching from the storage unit 220 for the web application to be removed when receiving the removal input.

For example, the service control unit 213 may compare the cache file attribute information with the URL address corresponding to the web application to be removed, and delete the cache file having the attribute information including the URL address.

As described above, according to the present invention, a URL address is removed from a URL list for a web application having a low frequency of use so that unnecessary update is not performed, and a cache file associated with a web application to be removed is deleted, The internal processing speed can be increased by securing the capacity.

According to the embodiment of the present invention as described above, the web application is connected to the web server 100 every time as a unique URL of the web application, and the local file of the offline web application is updated according to the web caching logic It can be updated by replacing it with an updated file upon connection to the Web server 100. [

Also, the web application may be managed by web caching logic, which is sent to the user device 200 as separate download logic via the web server 100 and is not installed. In the case of a web application having a requirement to be driven even when the web server 100 is not connected to the web server 100, the web application is implemented as an offline web application defined by the W3C and the web server 100 can not be accessed through the web- .

In addition, the present invention manages a web application used by a user through URL list management of a web application, and removes a specific web application from a list of URLs, if necessary, thereby removing the corresponding web application. In the case of the offline web application, if the URL is deleted from the URL list, the cached file is removed through a separate process.

By managing the application in this way, the application can be used through the caching file when offline while maintaining the latestness of the application at the time of online.
