1 is a block diagram illustrating a system for precaching web pages for offline execution according to the present invention.

Referring to FIG. 1, the pre-caching system of a web page for offline execution according to the present invention includes a caching service server 100 and a terminal device 200. In FIG. 1, reference numeral 300 denotes a network connecting the caching service server 100 and the terminal device 200, and 400 denotes a third service server providing a cached web page. In the present exemplary embodiment, the caching service server 100 is illustrated as being implemented separately from the third service server 400 that provides the actual caching page. Alternatively, the caching service server 100 and the caching service server 100 may be provided. The third service server 400 may be implemented as one server.

The caching service server 100 receives and registers a keyword from a user who requests a caching service, collects web page information related to the registered keyword, constructs a caching page list, and then configures a caching page list configured according to a pre-caching request. To the device 200. Here, the keyword is arbitrarily selected by the user, and it is preferable that one or more keywords are set for the object of interest. For example, the keyword may be variously set such as a name of a person who is interested in the user, an area of interest, an area of interest, a product name, a store name, a food name, and the like. As described above, when a keyword is registered, the caching service server 100 searches for a web page provided by the third service server 400 and extracts one or more pages related to the keyword. For example, when the third service server 400 is a server providing music service, if a user sets a singer's name as a keyword, the caching service server 100 may perform the third service server 400. Extracts a page related to the set mantissa from the. The extracted pages are collected to form a caching page list. The caching page list is provided to the terminal device 200 according to a pre-caching request from the terminal device 200.

Next, the terminal device 200 is a terminal device of a user who requested a caching service, requests a caching service to the caching service server 100 according to a user input, and transmits a registered keyword. Then, the terminal device 200 checks the network connection state of the terminal, and when a network connection is established, transmits a pre-caching request to the caching service server 100, the caching page consisting of a page related to the keyword After receiving the list, precaching is performed to receive one or more web pages included in the received caching page list in advance and store them in local storage. When the web page to be connected through the network 300 is called during the execution of any web application, the terminal device 200 searches for its own local storage and accesses the web page before accessing the corresponding address. Make sure it is precached. If the web page is pre-cached, the data of the page temporarily stored in the local storage is retrieved and displayed on the screen. In this case, the terminal device 200 can normally execute the web application even when offline. In addition, even when online, the data of the page stored in the local storage can be directly imported without a network connection, thereby reducing the screen output time. In addition, the terminal device 200 may delete the pre-cached pages according to a predetermined condition.

The terminal device 200 is a device capable of executing a web application and connecting to a network, for example, a personal computer (PC), a notebook computer, a mobile phone, a tablet PC, a navigation device, a smart phone ( It may be implemented by any one of a digital broadcasting receiver such as a smart phone, a personal digital assistant (PDA), a portable multimedia player (PMP), or a digital video broadcasting (DVB). Of course, this is only an example, and in addition to the above-described examples, it should be interpreted as a concept including all communication devices that are currently developed and commercialized or will be developed in the future.

The network 300 is a transmission path for transferring data between the caching service server 100, the third service server 400, and the terminal device 200. The network 300 may include any existing communication network and next-generation communication network. May also be implemented. For example, an IP network that provides a large-capacity data transmission / reception service and an uninterrupted data service through the Internet protocol, an all-IP network structure that integrates different networks based on IP, and a Wibro (Wireless Broadband) network. In addition, one or more known communication networks, such as a wireless LAN including a Wi-Fi network, a WPAN, a wired communication network, a mobile communication network, a high speed downlink packet access (HSDPA) network, and a satellite communication network, may be used. . In particular, in the case of smart phones, such as the recent spotlight, since not only a mobile communication network but also a communication through the Wi-Fi network, in this case, the network 300 may be a mobile communication network or a Wi-Fi network.

Finally, the third service server 400 may correspond to any kind of server that provides a web page to the terminal device 200 through the network 300. For example, a server that provides multimedia content such as a video or music, or a server that provides a social network service may be used.

In addition, the caching service server 100 may provide a precaching service for only web pages provided by a service server, or may provide a precaching service for web pages provided by a plurality of different servers. have. In the latter case, the caching service server 100 may set different keywords for each service for the same user. For example, in relation to a multimedia content service, a keyword for a genre of interest such as an action, a drama, a horror is set, and for a music t service server, a keyword for an interest singer is set as a keyword. Can be set.

Hereinafter, configurations and operations of the above-described caching service server 100 and the terminal device 200 will be described in more detail.

2 is a block diagram showing the configuration of the caching service server 100 in the pre-caching service system according to the present invention.

Referring to FIG. 2, the caching service server 100 according to the present invention includes a communication unit 110, a registration unit 120, a pre-caching execution unit 130, and a storage unit 140.

The communication unit 110 is a means for transmitting and receiving data through the network 300, and in particular, transmitting and receiving data with the terminal device 200 or a third service server 400 through the network 300. The communication unit 110 may include protocol processing means for performing processing according to a corresponding communication protocol according to the type of the network 300 to be connected.

The registration unit 120 receives and registers one or more keywords, which are criteria for performing caching, from a user who requests a caching service. More specifically, the registration unit 120 stores identification information (eg, user ID) of a user according to a caching service request from the terminal device 200, and receives and registers a plurality of keywords for the user. do. The keyword can be changed at any time at the request of the user. In addition, the registerer 120 may perform membership registration for the user who requested the caching service.

The pre-caching execution unit 130 collects web pages related to the keyword from the third service server 400 based on the plurality of keywords set in the registration unit 120 to form a caching page list, and the communication unit 110. When the pre-caching request is received from the terminal device 200 through), the configured caching page list is transmitted to the terminal device 200. The pre-caching execution unit 130 may interwork with a third service server 400 that provides the web page in order to collect web page information visited by the visit information collection target. That is, the keyword may be provided to the third service server 400, and corresponding information of the web page related to the keyword may be received from the third service server 400.

Finally, the storage 140 stores one or more of the registration information 141 of the user who requested the caching service and the caching page list 143 configured for the user. The registration information 141 of the user includes user identification information and one or more keywords selected by the user. The caching page list 143 is composed of pages related to the keyword.

3 is a flowchart illustrating an operation of a caching service server 100 according to a method of precaching web pages for offline execution according to the present invention.

Referring to this operation of the caching service server 100 will be described as follows.

That is, the caching service server 100 registers a user who will provide a caching service according to a user's request (S110). When registering a user, the user's identification information is basically set, and a range to be pre-cached (for example, a service name or a service server address) can be set. If the caching service server 100 is implemented with a third service server 400 that provides a specific service and one server, precaching may be performed only for web pages provided by the caching service server 100. In this case, caching There is no need to set the range.

In addition, the caching service server 100 receives and sets one or more keywords from the terminal device 200 of the user who requested the caching service (S120). When a plurality of service servers are designated as a range to be pre-cached in operation S110, keywords may be set for each service server.

When the keyword is set as described above, the caching service server 100 collects pages related to the set keyword from the corresponding third service server 400 to construct a caching page list (S130). In step S130, the caching service server 100 may interwork with a third service server 400 to collect web page information related to a keyword. That is, the keyword may be provided to the third service server 400, and corresponding web page information related to the keyword may be received from the third service server 400.

In addition, the step S130 may be repeated until a pre-caching request is received from the terminal device 200 of the user who requested the caching service.

When a pre-caching request is received from the terminal device 200 of the user who requested the caching service (S140), the caching service server 400 transmits the caching page list configured up to the corresponding time point to the terminal device 200 (S150). ). The caching page list transmitted to the terminal device 200 may be deleted, and then the caching page list may be reconstructed by the caching service server 100.

4 is a block diagram showing the configuration of the terminal apparatus 200 in the pre-caching system for web pages for offline execution according to the present invention.

Referring to FIG. 4, the terminal device 200 may include a communication unit 210, an input unit 220, a control unit 230, a storage unit 240, and a display unit 250.

The communication unit 210 is a means for transmitting and receiving data through the network 300, and the terminal device 200 transmits and receives data to and from the caching service server 100 or the third service server 400 through the communication unit 210. .

The input unit 220 generates a user input signal according to a user's manipulation. The input unit 220 may be implemented as various input devices that are commonly used, for example, a keyboard, a mouse, a touch screen, a touch pad, a gesture input unit, a joystick, and the like.

When the terminal device 200 is connected to the network 300, the controller 230 requests the caching service server 100 through the communication unit 210 to receive a caching page list including pages related to a keyword registered in advance. In the waiting state, precaching is performed on the data of the page included in the caching page list. That is, when the pages included in the caching page list are in a standby state, the pages are received one by one and stored in the local storage, that is, the storage unit 240. In addition, before receiving the caching page list, the controller 230 may request a caching service to the caching service server 100 according to a user's input, and transmit a keyword to be pre-cached to request registration. In addition, before receiving the caching page list, the controller 230 may set precaching activation or deactivation according to a user's input signal transmitted from the input unit 220. Receive caching page list and pre-cache pages. In addition, when the pre-caching activation is set, the controller 230 needs information for accessing the caching service server 100 for the pre-caching request, that is, address information and access authentication information (for example, the caching service server 100). , User ID and PW) can be received from the user and further stored.

In addition, when an arbitrary page connected through the network 300 is called during the execution of any web application, the controller 230 first searches for the local storage of the terminal device 200, that is, the storage unit 240. In addition, the controller determines whether the page is a pre-cached page, and if the page is a pre-cached page, the storage unit 240 obtains and outputs data of the corresponding page. Accordingly, the terminal device 200 can normally execute the web application even when offline. In addition, even in an online state, since the data of the page stored in the storage unit 240 can be directly imported without a network connection, the screen output time can be shortened.

Subsequently, the storage unit 240 is a local storage for temporarily or semi-permanently storing data in the terminal device 200. The storage unit 240 controls the caching page list 242 received through the communication unit 210 and the control unit 230. Store one or more of the pre-caching pages 242 previously received. The storage unit 240 may include a main memory such as a RAM (Read Access Memory) and an auxiliary memory such as a hard disk drive (HDD) or a flash memory.

Finally, the display unit 250 outputs the called page under the control of the controller 230. The display unit 240 may be implemented as, for example, a liquid crystal display (LCD) or a touch screen. In particular, the display unit 240 may include some or all of the functions of the input unit 220.

Next, FIG. 5 is a flowchart illustrating the operation of the terminal device 200 according to the pre-caching method of the web page for offline execution according to the present invention.

Referring to this, when the operation of the terminal device 200 is described, the terminal device 200 requests a caching service to the caching service server 100 according to a user input, and transmits a keyword to be pre-cached (S210). ).

In addition, the terminal device 200 sets whether to enable precaching according to a user's input (S220). In this case, when the pre-caching is enabled, the terminal device 200 needs to access the caching service server 100 to obtain a caching page list, that is, address information of the caching service server 100 and the caching service server ( A step (not shown) of setting access authentication information for accessing 100 may be further performed. This may be omitted when the address information of the caching service server 100 and the access authentication information for accessing the caching service server 100 are preset or set as default.

When the pre-caching activation is set and connected to the network (S230 and S240), the terminal device 200 receives a caching page list composed of pages related to the transmitted keyword from the caching service server 100 ( In operation S260, precaching is performed on data of a page included in the received caching page list. The step S260 may be repeated until all pages included in the caching page list are cached (S270).

The terminal device 200 which pre-caches a web page that is likely to be visited by a user through the above-described process executes a web application using the data of the pre-cached page.

6 is a flowchart illustrating a step of executing a web application made in the terminal device 200.

Referring to FIG. 6, the terminal device 200 executes an arbitrary web application in response to a user's request (S310).

During execution of the web application, if any page existing in the network 300 is called (S320), the terminal device 200 first searches for local storage, that is, the storage unit 240, the page is called Check whether it is pre-cached (S330).

As a result of the check, if the called page is pre-cached and exists in the local storage, the terminal device 200 reads the data of the page from the local storage and displays it on the screen (S350 and S370).

On the contrary, if the called page is not pre-cached and does not exist in the local storage, the terminal device 200 connects to a network, requests and receives the corresponding page, and displays the received page on the screen as in the conventional processing procedure. (S360, S370)

FIG. 7 illustrates a process of processing a page read from local storage or taken from a specific address of a network.

In general, programming languages can be divided into imperative and declarative description languages. An imperative description language is a language that is written with an emphasis on how to solve it. It specifies the algorithm to be executed and does not specify the goal. Typical Fortran, C, and Java are imperative description languages. In contrast, a declarative description language is a language that is written with a focus on explaining what the 'solution' is. It specifies goals, not algorithms. Web pages processed in the present invention are usually written in a declarative description language.

Referring to FIG. 7, data 70 of a web page includes a markup language 71 and a style sheet 72. In addition, it may include a script language, but a description of a part of processing the script language will be omitted.

In step S410, the markup language 111 and the stylesheet 113 decompose the components into meaningful tokens according to the method of interpretation of the declarative description language, and analyze the hierarchical relationship therebetween to determine the structure of the sentence. Construct a parse tree. Here, the parse tree includes a Document Object Model (DOM) tree 73 and a style tree 74. That is, the markup language 71 is composed of a tag, its attributes, and plain text. The markup language 71 is decomposed and forms a DOM tree 73 according to each hierarchical relationship. The style sheet 74 has a style for specifying letters, margins, layout, and the like of the page 80 represented by the markup language 71. The style sheet 72 is decomposed so that a plurality of styles are hierarchically related. A style tree 74 arranged in a tree structure is configured accordingly.

Then, in operation S420, the DOM tree 73 and the style tree 74 are combined to form the renderer tree 75. Subsequently, in step S430, a layout suitable for a style is set through analysis of the renderer tree 750, and the page data 76 is generated by arranging values of each attribute in the corresponding layout. This page data 76 is data before being rendered and displayed as the page 80 on the screen.

When performing the pre-caching of the web page, the terminal device 200 configures the page data 76 by performing the above-described steps (S410 to S343) for each page, and the page data 76 You can change the structure of (serialization) and save it in binary form. As such, the page data stored in binary form will be referred to as binary page data 77. In this state, if the user requests to execute the corresponding page 10, the binary page data 77 may be directly rendered and output in operation S450.

The web page pre-caching method for offline execution according to the present invention may be implemented in software form readable through various computer means and recorded on a computer readable recording medium. Here, the recording medium may include a program command, a data file, a data structure, etc. alone or in combination. Program instructions recorded on the recording medium may be those specially designed and constructed for the present invention, or they may be of the kind well-known and available to those having skill in the computer software arts. For example, the recording medium may be magnetic media such as hard disks, floppy disks and magnetic tapes, optical disks such as Compact Disk Read Only Memory (CD-ROM), digital video disks (DVD), Magnetic-Optical Media, such as floppy disks, and hardware devices specially configured to store and execute program instructions, such as ROM, random access memory (RAM), flash memory, and the like. do. Examples of program instructions may include high-level language code that can be executed by a computer using an interpreter as well as machine code such as produced by a compiler. Such hardware devices may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be apparent to those skilled in the art. In addition, although specific terms are used in the specification and the drawings, they are only used in a general sense to easily explain the technical contents of the present invention and to help the understanding of the present invention, and are not intended to limit the scope of the present invention.

According to the present invention, after the web page information related to the keyword set by the user is configured to construct a caching page list, the terminal device displays the web page included in the caching page list when the terminal device is connected to the network and is in a standby state. By pre-caching to local storage, you can execute the web application by bringing the data of the previously cached page even in the offline state, and output the screen as the page data of the local storage directly without sending or receiving data through the network even when online. There is an excellent effect of improving performance.
