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, and 400 denotes a third service server that provides a cached web page. In the present embodiment, the caching service server 100 is illustrated as being implemented separately from the service server 400 that provides the actual caching page. In contrast, the caching service server 100 and the service server that provides the caching page ( 400 may be implemented as one server.

The caching service server 100 sets a plurality of visit information collecting targets for a user who has requested a caching service, collects web page information visited by the set plurality of visiting information collecting targets, constructs a caching page list, and then requests a pre-caching. Provides a list of caching pages. The plurality of visit information collection targets are set among an acquaintance of the user or other users having similar conditions with the user. Other users with similar conditions are those who match one or more of the primary information, including one or more of the user's gender, age, or place of residence, and the secondary information, including one or more of interests, hobbies, or tastes. it means. In addition, the web page collected by the caching service server 100 may be a web page provided by the caching service server 100 itself, or may be a web page provided by the third service server 400. . In the latter case, the caching service server 100 may collect the landing page information of the visitor collecting target information through interworking with the third service server 400.

Next, the terminal device 200 is a terminal device of a user who requested a caching service. When a network connection is made, the terminal device 200 transmits a pre-caching request to the caching service server 100 to have a similar condition with an acquaintance of the user or the user. After receiving a caching page list including pages visited by a visitor collecting information of other users, one or more web pages included in the received caching page list are previously cached. When the web page connected to the network is called during the execution of an arbitrary web application, the terminal device 200 first searches its own local storage and checks whether the web page is pre-cached before accessing the corresponding address. Check it. 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.

The terminal device 200 may be, for example, a personal computer (PC), a notebook computer, a mobile phone, a tablet PC, a navigation device, a smart phone, a personal digital assistant (PDA), or a PMP. It may include a digital broadcast receiver such as (Portable Multimedia Player) or DVB (Digital Video Broadcasting). 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 pre-caching service targeting only web pages provided by one service server, or target web pages provided by a plurality of different servers providing different kinds of services. You can also provide precaching services. In the latter case, the caching service server 100 may set the visit information collection target for the same user differently for a plurality of service servers subscribed to the user. For example, in relation to the multimedia content service, other users having similar conditions as the user may be set as the visit information collecting target, and in relation to the social network service, the user's acquaintances may be set as the visiting information collecting target. In this way, by setting the visit information collection target according to the characteristics of each service, it is possible to cache the page having a higher probability of the user visiting.

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 sets and registers a plurality of visit information collecting targets for the user who requested the caching service. More specifically, the identification information (for example, ID) of the user requesting the caching service is registered, and a plurality of visit information collection targets are set for the user, and the identification information of the plurality of visit information collection targets ( For example, ID). If necessary, the registration unit 120 may perform membership registration for the user who requested the caching service. As described above, the visit information collection target may be set among an acquaintance of the user or another user having similar conditions with the user. At this time, it is preferable that an acquaintance of the user who is set as the collection target information or another user who has similar conditions with the user is subscribed to the same service as the user. In addition, the registration unit 120 requests the terminal device 200 to set the visit information collection target through the communication unit 110 to set up the visit information collection target user, and then the user from the terminal device 200 correspondingly. Receive the information about the acquaintance, and can set the received acquaintances of the user as the target of the visit information collection. In another example, the register 120 may include, for the user to set up a visitor collection target, primary information including one or more of gender, age, and place of residence, and one or more of interests, hobbies, and tastes, for the user. Collect one or more of the secondary information, and extract other users having the same conditions as the collected user information from other users subscribed to the corresponding service, and set the extracted plurality of other users as visit information collection targets. Can be.

The pre-caching execution unit 130 collects the web page information visited by the plurality of visit information collection targets set by the registration unit 120 to construct a caching page list, and from the terminal device 200 through the communication unit 110. When the pre-caching request is received, 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 visitor collects information on the visitor to the third service server 400, and correspondingly, the visitor collects the visitor's information from the third service server 400. In addition, the pre-caching execution unit 130 may receive the page information visited by the visit information collection target from the terminal device 200 of the user set as the visit information collection target.

Finally, the storage 140 may include a caching page list including registration information 141 of a user who requested a caching service, a visit information collecting target list 142 set for the user, and a page visited by the visiting information collecting target ( 143) one or more of them. The user's registration information 141, the visitor information collecting target list 142, and the caching page list 143 are stored for each user who requested a caching service. Here, the user registration information 141 may be used to confirm the user before the caching execution unit 130 provides the caching page list according to the pre-caching request, and the visit information collection target list 142 may be the precaching execution unit. In operation 130, the caching page list may be referred to.

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, separated by 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 sets a plurality of visit information collection targets for the user who requested the caching service (S120). The visit information collection target may be set as an acquaintance of the user or another user having similar conditions with the user. The step S120 may include requesting, by the caching service server 100, the terminal apparatus 200 to set a visitor information collection target, and information on acquaintances of the user from the terminal apparatus 200 in response to the request. And receiving the acquaintance of the received user as a visitation information collecting target. That is, the caching service server 100 may receive and set acquaintance information of the user through the terminal device 200 of the user who requested the caching service in order to set the visit information collection target. In another embodiment, step S120 may include: primary information in which the caching service server 100 includes one or more of gender, age, and place of residence; and secondary, including one or more of interests, hobbies, and tastes. By extracting a plurality of other users belonging to a similar group with the user based on one or more of the information, it may be made by setting the plurality of visit information collection targets. Here, it is preferable that another user for setting the visit information collection target is set among users who use the same service as the user who requested the caching service. In the above description, a user who requests a caching service may be a visitor collecting target information of another user, and another user who is set as the visitor information collecting target may also be a caching service requester.

When the visit information collection target is set as described above, the caching service server 100 collects the web page information visited by the plurality of visit information collection targets set up 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 visited by a visitor. That is, the visitor collects information on the visitor to the third service server 400, and correspondingly, the visitor collects the visitor's information from the third service server 400. In addition, the caching service server 100 may receive the page information visited by the visited information collecting target from the terminal device 200 of the user set as the visited information collecting target.

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 is deleted and then reconfigured by collecting new visit information 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. do.

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 generate a list of caching pages including pages visited by a plurality of visitor information collecting targets. Receives and pre-caches the data of the page included in the caching page list when in the standby state. 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 storage unit 240. In addition, when the user is set as a visit information collection target, the controller 230 extracts and stores page information visited by the user in the storage unit 240 and provides the caching service server 100 with a network connection. Can be further performed. The landing page information provided to the caching service server 100 by the terminal device 200 may be used to construct a caching page list for another user in the caching service server 100.

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, the controller 230 receives acquaintance information of a user to be set as a visit information collection target through the input unit 220 according to a request of the caching service server 100, and caches the input acquaintance information of the user. The function of transmitting to the service server 100 may be further performed.

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, and is received through the landing page list 241 and the communication unit 210 generated by the controller 230. One or more caching page lists 242 and pre-caching pages 243 received in advance under the control of the controller 230 are stored. 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 240 outputs the called page under the control of the controller 230. The display unit 250 may be implemented as, for example, a liquid crystal display (LCD) or a touch screen. In particular, the display unit 250 includes 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, referring to the operation of the terminal device 200, the terminal device 200, according to the user input, sets whether to enable the pre-caching (S210). Here, when the pre-caching is set to active, 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 (S220 and S230), the terminal device 200 displays a caching page list including pages visited by a plurality of preset visit information collecting targets from the caching service server 100. In operation S260, precaching is performed on data of the page included in the received caching page list in operation S270. The step S270 may be repeated until all pages included in the caching page list are cached (S280).

In addition, the terminal device 200 may collect and store the landing page information of the user when the network is connected (S240), and transmit the stored landing page information of the user to the caching service server 100 (S250). The steps S240 and S250 may be selectively performed when the user of the terminal device 200 is set as a collection target for visiting information about another user.

Although not shown in FIG. 5, the terminal device 200 accesses the caching service server 100 to request a caching service and performs user registration before performing the above-described pre-caching processes S210 to S280. can do. In addition, in the caching service request registration process, in response to the request of the caching service server, the terminal device 200 receives the acquaintance information of the user to be set as the visit information collection target, and transmits to the caching service server 100 Can be further performed.

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 on the network is called (S320), the terminal device 200 first searches for local storage, that is, the storage unit 240, the page is pre-caching Check whether it is (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 is a diagram for describing a method 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.
