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

As shown, the web server 100 is connected to the user device 200 through a communication network and provides a web application to the user device 200 , and web application related data provided from the web server 100 . A cloud streaming server (Cloud Streaming Server: CSS) that receives and executes the web application-related data from the user device 200 and the web server 100 and transmits the result information generated by the streaming method to the user device 200 (300) may be included.

In this case, the user device 200 may be configured as a set-top box (STB), in addition to a smart phone having a communication function, a portable terminal, and a mobile terminal. , Personal Digital Assistant (PDA), PMP (Portable Multimedia Player) terminal, Telematics terminal, Navigation terminal, Personal Computer, Notebook computer, Slate PC, Tablet PC (Tablet PC), ultrabook (ultrabook), wearable device (including watch-type terminal (Smartwatch), glass-type terminal (Smart Glass), HMD (Head Mounted Display), etc.), WiBro ) terminal, IPTV (Internet Protocol Television) terminal, smart TV, digital broadcasting terminal, AVN (Audio Video Navigation) terminal, A/V (Audio/Video) system, flexible terminal, etc. have.

In addition, the web server 100 and the cloud streaming server 300 and the user device 200 may communicate with each other through a wired / wireless communication network, and as an example of such a wireless communication network, a wireless LAN (WLAN), DLNA ( Digital Living Network Alliance), Wireless Broadband (Wibro), Wimax (World Interoperability for Microwave Access: Wimax), GSM (Global System for Mobile communication), CDMA (Code Division Multi Access), CDMA2000 (Code Division Multi Access 2000) , Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), IEEE 802.16, Long Term Evolution (Long Term Evolution) Term Evolution: LTE), Long Term Evolution-Advanced (LTE-A), 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 Fi), Wi-Fi Direct, and the like may be included. In addition, the wired communication network may include Power Line Communication (PLC), USB communication, Ethernet, serial communication, optical/coaxial cable, and the like.

In the above configuration, the user device 200 provides selection information on a web application to be executed by accessing the web server 100 through a communication network, and the web server 100 provides the user device 200 according to the selection information. It is possible to extract the web application-related data requested from the application DB and transmit it to the web browser of the user device 200 .

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

In this case, when the user device 200 connects to the web server 100 , the user device 200 requests an application profile for the web application selected by the user device 200 to the web server 100 , and the web server 100 sends the requested web application An application profile corresponding to can be extracted from the application DB and transmitted to the user device 200 .

Here, the application profile includes the occupancy of each resource for the main processor (CPU), memory, graphic processor (GPU), etc. when executing (driving) the web application for each web application that is a service target, and HTML5 functions necessary for running the web application. It contains information about the requested resource.

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

On the other hand, the user device 200 is available for each resource of the main processor (CPU), memory, graphic processor (GPU), etc. configured in the user device 200 that can be used for the web application and HTML5 that can be supported for the execution of the web application. Information on available resources including functions and the like may be stored as a device profile.

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

Thereafter, the user device 200 receives and executes the web application-related data requested 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 streaming server 300 to the web server 100 ), the result information generated by the execution may be received from the cloud streaming server 300 in a real-time streaming manner to execute a web application through web virtualization.

At this time, when an example of servicing a web application in a cloud streaming method through the cloud streaming server 300 is described in detail with reference to FIG. 2 , first, the cloud streaming server 300 is the user device 200 from the web server 100 After receiving the selected web application-related data, driving (executing) the web application program, compressing the image information and audio information output according to the web application operation in real time to generate the result information, and then streaming it to the user device 200 in real time ( live streaming).

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

Accordingly, the user device 200 receives the result information transmitted in real time, separates the image information and the audio information, and provides image information and audio information based on the synchronization information included in the image information and the audio information. It can be synchronized and played through the web browser of the user device 200 .

In this case, the user device 200 may decode the image information and the audio information by a decoding method corresponding to the compression method of the image information and the audio information, and then output and reproduce the image information and the audio information that have undergone a rendering process.

Meanwhile, the user device 200 outputs image information transmitted in real time through the screen in real time according to the driving of the web application, and a touch input or key for operating the web application while checking the operating status of the web application output on the screen. Upon receiving the input, the user input information may be generated and transmitted to the cloud streaming server 300 in real time.

Accordingly, the cloud streaming server 300 executes a function related to the web application corresponding to the user input information, and then transmits image information and audio information about the execution result to the user device 200 in real time in a streaming manner. .

In this way, the cloud streaming server 300 provides the result according to the execution of the web application as an image, and when user input information for the operation of the web application is received from the user device 200, the web application corresponds to the user input information. It is executed and the result is provided as an image in real-time streaming, so that the web application can be virtualized and provided.

Therefore, according to the present invention, when the available resources of the user device 200 do not satisfy the required resources required for the execution of the web application, the web application can be provided in the form of an online web application based on the cloud streaming server 300, and cloud streaming Since the web is provided by virtualization based on the , unrestricted services such as the main processor, graphic processor, and memory of the user device 200 are possible.

Meanwhile, in the above configuration, the user device 200 may manage various web applications serviced from the web server 100 by the web caching logic, and store the cache file (temporary file) generated through the web caching to the user device ( 200) can be stored in the configured storage unit. In addition, 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.

At this time, the storage unit configured in the user device 200 is a flash memory type (Flash Memory Type), a hard disk type (Hard Disk Type), a multimedia card micro type (Multimedia Card Micro Type), a card type memory (eg, SD or XD memory), magnetic memory, magnetic disk, optical disk, RAM (Random Access Memory: RAM), SRAM (Static Random Access Memory), ROM (Read-Only Memory: ROM), EEPROM (Electrically Erasable Programmable Read-Only Memory) ) and PROM (Programmable Read-Only Memory) may include at least one storage medium. In addition, the user device 200 may operate a web storage that performs a storage function of the storage unit 220 on the Internet, or may operate in connection with the web storage.

Accordingly, the user device 200 preferentially accesses the cache file to execute the web application when the previously serviced web application is to be serviced again through the web browser, so that the web server 100 converts the web application to a new version. If it is updated (updated), the latest web application will not be serviced.

In particular, a web application having a requirement to be driven even when not connected to the web server 100 is implemented as an offline web application stipulated by the World Wide Web Consortium (W3C). There is a problem in that the web application cannot be maintained up-to-date by preferentially executing the cached file.

On the other hand, when a user wants to remove a web application that he does not want to receive service anymore, he or she must directly find and remove a cache file related to the web application to be removed. Internal processing speed may be reduced. Such a decrease in memory efficiency causes a decrease in the service quality of the web application service.

Accordingly, a configuration is required to support the efficient management of the web application serviced from the web server 100 in the user device 200 .

Hereinafter, a detailed configuration of the user device 200 according to an embodiment of the present invention for efficiently managing a web application will be described with reference to the drawings.

In addition, the communication unit 230 is a wireless LAN (Wireless LAN: WLAN), DLNA (Digital Living Network Alliance), WiBro (Wireless Broadband: Wibro), Wimax (World Interoperability for Microwave Access: Wimax), GSM (Global System for Mobile communication) ), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data 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-A), Wireless Mobile Broadband Service (WMBS), Bluetooth (Bluetooth), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, Near Field Communication (NFC), Ultra Sound Communication: USC), Visible Light Communication (VLC), Wi-Fi (Wi-Fi), Wi-Fi Direct (Wi-Fi Direct), such as a wireless communication method may be supported. In addition, the communication unit 230 may support a wired communication method such as Power Line Communication (PLC), USB communication, Ethernet, serial communication, and optical/coaxial cable.

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

In addition, the storage unit 220 is a flash memory type (Flash Memory Type), a hard disk type (Hard Disk Type), a multimedia card micro type (Multimedia Card Micro Type), a card type memory (eg, SD or XD memory) etc.), magnetic memory, magnetic disk, optical disk, RAM (Random Access Memory: RAM), SRAM (Static Random Access Memory), ROM (Read-Only Memory: ROM), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory) may include at least one storage medium. In addition, the user device 200 may operate a web storage that performs a storage function of the storage unit 220 on the Internet, or may operate in connection with the web storage.

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 controller 210 may include RAM, ROM, CPU, GPU, and a bus, and the RAM, ROM, CPU, GPU, etc. may be connected to each other through a bus. The control unit 210 may access the storage unit 220 to perform booting using an O/S (Operating System) stored in the storage unit 220 , and various programs, contents, Various operations may be performed using data or the like.

Based on the above-described configuration, 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 an update as shown. A management unit 216 may be included.

In this case, each unit constituting the control unit 210 may be implemented by a hardware circuit (eg, a CMOS-based logic circuit), firmware, software, or a combination thereof. For example, it may be implemented using 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 in the memory of the user device 200 . The memory may be an internal memory of the user device 200 , an external memory, or another type of storage device. Also, 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 a specific operation.

First, the device profile manager 211 generates a device profile that is information about available resources for the main processor, memory, graphic processor, and HTML5 function supported by the user device 200 configured in the user device 200 , and generates a storage unit (220) can be stored.

In addition, the application profile collection unit 212 requests an application profile for the web application selected by the user device 200 when accessing the web server 100 , and receives the application profile from the web server 100 to receive the service control unit ( 213) can be used.

On the other hand, 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 application profile collection unit 212, device profile or current device availability information. It can be determined whether the web application is performed locally through the web browser or the web application service is provided in the cloud streaming method through the cloud streaming server 300 by comparing the application profile with the will be described with reference to

First, as shown, the service control unit 213 may load a web browser and connect to the web server 100 through the communication unit 230 , and may transmit selection information about a web application to be executed to the web server 100 . and may receive an application profile for a 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 with the device profile stored in the storage unit 220 to determine whether the available resources according to the device profile satisfy the requested resources according to the application profile (whether the available resources are greater than or equal to the required resources) Depending on whether or not the web application is locally performed through a web browser, it may be determined whether the web application service will be provided in a cloud streaming manner through the cloud streaming server 300 .

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

In this case, the web server 100 may extract web application related data corresponding to the selection information from the application DB 101 and provide it to the user device.

On the other hand, the service control unit 213 connects to the cloud streaming server 300 through the communication unit 230 to execute the web application in the cloud streaming method according to the determination result, and corresponds to the selection information from the cloud streaming server 300 . Result information provided in real-time streaming can be received according to the execution of the web application.

For example, when the service control unit 213 does not satisfy the resources required to service the web application according to the resource availability state of the user device 200 , the service control unit 213 interworks with the web server 100 to provide a web application desired by the user device 200 . By accessing the cloud streaming server 300 that executes the related data, captures the video and audio according to the execution, and transmits the result information generated to the user device 200 in a live streaming method, the cloud streaming server ( 300), result information according to the execution of the web application may be received in real-time streaming through the communication unit 230, and the web application may be executed through 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 it 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) can be printed.

Meanwhile, the device profile manager 211 may generate device availability information, which is information on a spare resource allocable to a web application among available resources, according to the driving state of the user device 200 , and store it in the storage 220 .

In this case, the device availability information is based on the operating state of the user device 200 among available resources including availability of the main processor, memory, and graphic processor, and HTML5 functions supportable for the execution of a web application in the user device 200 . Accordingly, information on free resources that can be allocated to the web application may be included.

In this case, the device profile manager 211 may manage the device availability information separately from the device profile and store it in the storage 220 , or may update the device profile by replacing it with the device availability information.

Accordingly, when the device profile of the user apparatus 200 satisfies the condition of the application profile, the service controller 213 may compare the current device capability information of the user apparatus 200 with the application profile.

Then, the service control unit 213, if the current device availability information does not satisfy the application profile (when the spare resource according to the device availability information is smaller than the required resource according to the application profile) through the web application through the cloud streaming server (300) If it is executed and serviced in a real-time streaming method and is satisfied (when the free resource according to the device availability information is larger than the required resource according to the application profile), it 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-described embodiment, the service control unit 213 may be executed as an offline web application based on the web caching logic.

The service control unit 213 may determine whether the web application to be executed is an offline web application to be executed offline with reference to the content defined in the application profile.

For example, in the case of a web application that requires offline operation or a concurrent service user rate (CSUR) greater than a preset reference value, the web server 100 caches the web application when receiving web application related data from the user device 200 . In order to enable the execution of the web application even when access to the web server 100 is unavailable using a cache file generated through .

Accordingly, the service control unit 213 may 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 with reference to the application profile.

In this case, 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 with the web server 100 is cut off, the service control unit 213 may execute a web application in an offline state using a cache file generated through web caching.

Through the configuration as described above, 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, device availability information, and the application profile. Since the service can be determined and serviced, even for an application that cannot be executed with the available resources of the user device 200, the application can be easily executed without software and hardware limitations, and the locally executable application can be executed locally and smoothly. A web application service can be provided.

In addition, when the web application service is performed, the user device 200 can determine the current operating situation and based on this, determine whether the web application can be executed with a spare resource to adaptively determine the service type, through which the web application service can be smoothly serviced It is possible to provide and at the same time reduce the communication load.

In addition, the user device 200 adaptively classifies offline web applications that require offline execution even when the connection with the web server 100 is cut off, and provides a web application to be executed in an offline state through web caching, thereby providing smooth We can support the continuity of the service.

Meanwhile, in the above configuration, when the service control unit 213 connects to the web server 100 and executes the same application as the previously executed web application, it accesses a cache file created and stored through web caching to execute the web application. However, when a web application is executed only with a cache file, it is difficult to maintain the latest web application, and accordingly, the web server 100 cannot use various services updated for the web application.

Therefore, there is a need to manage the web application used by the user to maintain the up-to-dateness. It is important to manage

A configuration for this will be described with reference to the configuration of FIG. 3 with reference to FIG. 5 .

As described above, 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, the address acquisition unit 214 accesses the web server 100 from the service control unit 213 to receive related data for the execution of the web application, the URL accessed by the service control unit 213 to execute the web application. The (Uniform Resource Locator) address may be extracted from the web browser loaded by the service control unit 213 .

Accordingly, the address acquisition unit 214 may acquire the URL address related to the web application executed by the service control unit 213 .

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

In this case, the address management unit 215 has already created a URL list, and when the corresponding URL address does not exist in the URL list because the web application executed by the service control unit 213 has not been executed before, the current service control unit is added to the URL list. The URL list may be updated by adding the URL address related to the web application executed by step 213 to the URL list.

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

On the other hand, as described above, the service control unit 213 receives the web application-related data and executes it without installing it on the user device 200 , and generates a cache file through web caching when the web application is executed and the storage unit 220 . can be stored in

Thereafter, when re-executing a web application executed in the past, the service control unit 213 executes it using the cache file stored in the storage unit 220 without accessing the web server 100 , in particular, the web server 100 . In the case of a web application defined as an offline web application that needs to be driven offline in the application profile received from the web application, even if access to the web server 100 is possible, the web application is first executed using a cache file without access.

As a result, even when the web server 100 updates the web application running on the user device 200 , the service control unit 213 of the user device 200 executes the web application before the update, so the updated service will not be able to use

Accordingly, the user device 200 according to an embodiment of the present invention supports to receive an updated service by always maintaining a web application in the latest state, which will be described in more detail with reference to FIG. do.

As shown, the update management unit 216 may obtain a URL address when a web application executed through a web browser loaded in the service control unit 213 is executed, and is included in the URL list in conjunction with the address management unit 215 . It is possible to compare the URL address of each web application that has been created and the URL address of the executed web application.

Accordingly, if a 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 previously executed, and the corresponding web application A notification signal for update may be provided to the service control unit 213 in order to keep the service state of the .

For example, as shown, if the URL address for 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 been previously executed, , a notification signal for updating the service state of the web application 1 to the latest state is provided to the service control unit 213 .

Accordingly, when receiving a notification signal from the update management unit 216 , the service control unit 213 may switch online to access the URL address for the web application 1 executed offline by using the cache file.

Thereafter, the service control unit 213 accesses the web server 100 according to the URL address of the web application 1 to receive the latest update information related to the web application 1, and uses the update information to access the existing web application related data. The updated or replaced web application 1 may be executed with the updated web application related data. In this case, the update information may mean updated web application 1 related data, and of course, 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 for the web application 1 with the updated cache file. or can be updated.

Meanwhile, in the above configuration, the update management unit 216 may acquire the URL address through the address acquisition unit 214 .

In addition, as described above, when 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, the update management unit 216 connects to the URL address of the web application and accesses the web server ( Version information about the same web application as the web application currently executed in the user device 200 may be received from 100 , and the web application executed using the cache file stored in the storage unit 220 of the user device 200 . version information can be compared with each other.

Accordingly, the update management unit 216 determines the version according to the version information of the web application executed by the service control unit 213 using the cache file according to the version information of the web application provided from the web server 100 . If the version is older than the version, a notification signal for updating the currently executed web application may be provided to the service control unit 213 to be updated.

Also, 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 configuration as described above, a list of web applications executed in the past can be managed, and through this, the web application is managed to keep the latest state whenever the same web application is executed again, so that the updated service is provided to the user. can be made available.

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 operation or the offline application included in the application profile provided from the application profile collection unit 212 is an offline application, and determines Result In case of offline web application, it can be executed using cache file cached through web caching.

At this time, unlike other web applications, the offline web application has a requirement to be driven even when the web server is not connected, and is implemented as an offline web application stipulated by the W3C, so the service control unit 213 ) can execute the offline web application as it is through the cached web cache file even when the web server 100 is unavailable.

Therefore, even when the service control unit 213 receives a notification signal for an update from the update management unit 216, when the web server 100 is not accessible, it is difficult to update the offline web application, so it is difficult to provide the latest web application, Unlike other applications, in the case of an offline web application, since it can be continuously executed only with a cache file, the service in the state before the update is continued, and even when the web server 100 is switched to a state in which access is possible, the service in the previous state is continued. .

Accordingly, in order to update the service state of the offline web application that continues the service even when the user device 200 cannot access the web server 100, the update management unit 216 performs the application profile collection unit 212 to update the service state to the latest state. An application profile may be received from , and it may be determined whether the web application executed by the service control unit 213 is an offline web application based on the corresponding application profile.

In addition, the update management unit 216 may obtain the URL address of the corresponding offline web application through the address acquisition unit 214 and compare it with the URL list, and as a result of determining the web application currently executed through the service control unit 213 , offline In the case of a web application and a web application existing in the URL list, access may be determined by attempting to access the URL address of the offline web application periodically or in real time through the communication unit 230 .

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

That is, the update management unit 216 immediately provides a notification signal to the service control unit 213 when access to the web server 100 is possible, but when access to the web server 100 is not possible, as described above, the web server ( 100) may be determined when access is possible, and a notification signal may be provided to the service control unit 213 .

At this time, the state in which access to the web server is impossible occurs due to various factors such as a failure in the communication state of the user device 200 or the web server 100 or a state in which only access to the URL address corresponding to the offline web application is impossible. may be included.

Accordingly, when the service control unit 213 receives a notification signal while the offline web application is running, it determines that access is possible with the URL address of the offline web application, and responds to the offline web application by accessing the URL address of the offline web application It is possible to receive updated information from the web server 100 and use the update information to update offline web application-related data to the latest state.

In addition, the service control unit 213 may generate a cache file through web caching when the offline web application updated with the update information is executed, and is stored 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 query information on whether to proceed with the update through the output unit 240 when the notification signal is received, and response information according to a user input through the user interface unit 250 in response to the query information Of course, it is possible to access the web server 100 and update the running offline web application only when the update is in progress by receiving and determining based on the corresponding response information.

In this way, the user device 200 according to the present invention can continuously access the URL address of the offline web application during execution of the offline web application requiring offline operation (execution) even when access to the web server 100 is unavailable. It can be checked whether or not it is available, and if it is accessible, it can be updated during execution to ensure that the service is up-to-date.

That is, since an offline web application requiring offline operation can be easily and automatically updated, the service state of the offline web application can be maintained up to date.

Accordingly, the user does not need to separately download web application-related update information, and it is supported to maintain the latest status through updates every time it is executed, thereby increasing user satisfaction with the web application service, and at the same time increasing user convenience by supporting automatic updates. .

Meanwhile, in the above configuration, the service control unit 213 may allow only the web application that the user wants to manage so that the latest is always maintained according to a user input through the user interface unit 250 to be added to the URL list.

For example, whether the service control unit 213 adds the URL address of the corresponding web application to the URL list through the output unit 240 when the web application is executed through a web browser according to a user input through the user interface unit 250 . You can print query information about

Accordingly, the service control unit 213 receives response information according to a user input through the user interface unit 250 in response to the corresponding query information, and adds the currently executed web application to the URL list based on the response information. If desired, the URL address is obtained by controlling the address acquisition unit 214, and the URL address of the currently executed web application is added to the URL list through the address management unit 215, or a URL list including the URL address is generated. can make it happen

Thereafter, the service control unit 213 may perform an update through the web server 100 as described above whenever a web application included in the URL list is executed.

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, so that the cache file of the web application with low frequency of use is constant. By deleting it over time, it is possible to efficiently manage web applications that are frequently used.

On the other hand, the present invention supports to secure the resource capacity of the user device 200 necessary for web application management by removing the web application that the user does not want from the URL list, and also removes the cache file related to the web application to be removed. By doing so, it is possible to allocate resources to the execution of other web applications, thereby increasing the internal processing speed of the user device 200 and thereby improving the service quality.

In addition, it is possible to increase user convenience by deleting all data stored in the user device 200 related to the web application only by a removal input, which 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 may receive a selection input for uninstalling a specific web application through the user interface unit 250 , and may remove the web application to be uninstalled according to the selection input.

For example, when receiving a selection input for removal, 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 .

At this time, the address management unit 215 may receive the identification information related to the web application corresponding to the URL address from the web server 100 by accessing the URL address when receiving information about the URL address from the address acquisition unit 214, A URL list may be created by matching the URL address with 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, and receives identification information related to the web application to be removed through the user interface unit 250, A URL address matching the corresponding identification information can be removed.

In addition, the service control unit 213 may delete a cache file generated through web caching with respect to a web application to be removed from the storage unit 220 when a removal input is received.

For example, the service control unit 213 may search for attribute information for each cache file by comparison with a URL address corresponding to a web application to be removed, and delete the cache file having attribute information including the URL address.

As described above, the present invention prevents unnecessary updates by removing a corresponding URL address from a URL list for a web application with low frequency of use, and deletes a cache file related to a web application to be removed at the same time, so that the memory resource By securing the capacity, it can be provided so that the internal processing speed can be increased.

Through the embodiment of the present invention as described above, the web application connects to the web server 100 each time with a unique URL of the web application when running and maintains the latest state, and the local file of the offline web application is stored according to the web caching logic. When accessing the web server 100 , the update may be performed by replacing the updated file.

In addition, the web application may be managed by the web caching logic, and the web application is transmitted to the user device 200 as a separate download logic through the web server 100 and is not installed. In the case of a web application having a requirement to be driven even when not connected to the web server 100, the web application is implemented as an offline web application stipulated by the W3C, and when the web server 100 cannot be accessed through a web cached file, the web application is it works

In addition, the present invention manages the web application being used by the user through the URL list management of the web application, and if necessary, the web application can be removed by removing a specific web application from the URL list. In the case of an offline web application, if it is deleted from the URL list, a separate process is used to remove the cached file.

By managing the application in this way, it is possible to use the application through a caching file when offline while maintaining the up-to-dateness of the application when online.
