2 is a view illustrating in detail the configuration of the terminal and the user identification module shown in FIG.

3 is a signal flow diagram between components of a system for providing a web service according to an exemplary embodiment of the present invention.

The present invention relates to a method and apparatus for improving a response time of a user by reducing a delay time when a wireless Internet web service is provided using a terminal, and more particularly, to a system of the terminal. The present invention relates to a web service response improving method and apparatus using a module, and a system thereof.

Here, the user identification module is a module that performs functions such as registration and authentication of a user when communicating through the terminal.

Currently, web services through terminals are typically synchronous. In other words, when an address URL (Uniform Resource Locator) corresponding to a web page is input by a user through a browser interface inside the terminal, the terminal provides the input user request to the web server in the form of an HTTP request message. The web server then presents the web page according to the user input and generates the content content that the user last selected. At this time, the web server can use database, backend processing, etc. as needed. Such content is provided to the browser interface of the terminal in the form of a combination of HyperText Markup Language (HTML) and Cascading Style Sheet (CSS) data. Accordingly, the terminal displays the content content provided from the web server on the screen for the user to view.

However, the direct data transmission and reception with the web server through the browser interface may cause a significant delay when a large amount of content is provided, and an error may also occur when an abnormal download occurs. This method has a problem in that, if the content content is displayed for a long time, the user may be bored as the response is delayed or mistaken for an abnormality in the wireless Internet connection.

As a method for eliminating the delay due to the direct transmission and reception of the browser interface and the external web server, there is a method of implementing the user identification module mounted on the terminal, for example, a smart card, without the web server being external. This method is called a smart card web server (SCWS) method. In the SCWS method, since the web server is implemented in the smart card, the user hardly realizes the delay between the browser interface and the web server. Therefore, the user can feel the improved web service response compared to the existing method.

However, the SCWS method has limitations in receiving large contents or providing various contents due to the limited memory capacity of the smart card, and it is not possible to update the latest contents whenever necessary from the web server due to the predetermined update cycle. have.

As described above, the method of receiving a web service through direct transmission and reception with a web server in a conventional terminal is directly affected by network conditions such as an abnormality in a transmission / reception path and a response delay. In addition, the method of receiving a web service from a web server implemented in a smart card inserted into a terminal has a problem that it is difficult to provide various contents due to the limitation of smart card capacity.

Accordingly, the present invention provides a method and apparatus for improving a web service response using a user identification module of a terminal, and a system for reducing a delay time when receiving a wireless internet web service and improving a user's response speed.

The system of the present invention for achieving the above object is a terminal for transmitting a user input processing request to the user identification module in response to a user input, and receives and displays the content content according to the user input corresponding to the delivery; A user identification module for generating content contents corresponding to the user input and transmitting the contents to the terminal based on resources necessary for processing the user input; and an external web server for providing the corresponding resource in response to a request from the user identification module. And the user identification module is asynchronously connected to the external web server in preparation for user input, and receives and stores the corresponding resource.

The method may further include: transmitting, by the terminal, a user input processing request to the user identification module in response to a user input; and when the request is received, the user input module is based on resources required for processing the user input. To generate and deliver the contents to the terminal, and to asynchronously connect to the external web server in response to a user input to receive the corresponding resources, and to receive and display the contents from the user identification module. Include.

The terminal may also transmit a user input processing request in response to a user input for manipulating a key input unit, and display a content on the screen provided in response to the request, and between the browser module and the user identification module. It includes a connector module that acts as a protocol conversion and gateway, and is mounted on the terminal, and generates the corresponding content content based on the resources required to process the user input in response to a user input processing request from the connector module And a user identification module for transmitting to the connector module and asynchronously connected to the external web server in preparation for user input and receiving and storing the corresponding resource.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

The present invention implements a function for reducing a response delay when providing a web service in a terminal, and the web service includes not only a service through a web browser but also a data service and an internet service. Specifically, the terminal according to the present invention receives a user's wireless Internet web service access command or a command for receiving a web service through a browser interface in the terminal. Thereafter, the terminal transmits a user command to a user identity module (UIM) mounted on the terminal, and the user identification module performs a process corresponding to the user command by itself and delivers the processing result to the browser interface again. To be displayed on the screen. In this case, the user identification module may asynchronously access an external web server and receive the corresponding resource in advance in case there is no resource required to process the user command. In this way, the terminal does not connect to an external web server each time to provide a web service, and the user identification module processes the device itself, thereby reducing network traffic and improving user response speed.

On the other hand, the user identification module is equipped with an AJAX engine to perform the above functions, the user identification module according to an embodiment of the present invention smart card (Smart Card), SIM card (SIM Card), a variety of removable media ( Removable Media) and other memory cards with other security features.

Prior to describing the present invention, the AJAX method used in the present invention will be briefly described.

In general, AJAX (Asynchronous Javascript and XML) method is proposed in a wired environment. When a user's command is input to a browser interface such as a PC, the user's command is transmitted to the AJAX engine through a JavaScript call in the browser interface. . The AJAX engine then creates a service corresponding to the user input and provides it to the browser interface. In the present invention, the AJAX engine is mounted on the user authentication module to reduce the response delay caused by the transmission and reception with the external web server, and asynchronously loads content for user commands not provided by the AJAX engine. Pre-loading is requested by an external web server in advance.

Hereinafter, a system configuration diagram according to an embodiment of the present invention in which such a function is implemented will be described with reference to FIG. 1.

In FIG. 1, a system to which the present invention is applied includes a terminal 105 including a user identification module 115, an external web server 130, and an information providing system 140.

Specifically, the terminal 105 includes a browser module 100, a connector module 110, and a user identification module 115. The user identification module 115 attached to the terminal 105 is an AJAX engine, SCAE. (Smart Card Ajax Engine) module 120 is mounted. The browser module 100 of the terminal 105 transmits a message such as a JavaScript call to the connector module 110 in response to a user input of a user operating a key input unit. This user input may include selecting one of the menus having multiple structures, entering a site access command, or executing a desired URL. The connector module 110 converts the message transmitted from the browser module 100 into the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol for delivery to the SCAE module 120 of the user identification module 115. do. In addition, the connector module 110 serves to deliver a web service such as content delivered from the SCAE module 120 of the user identification module 115 to the browser module 100. As such, the connector module 110 serves as a protocol conversion and gateway between the browser module 100 and the SCAE module 120 of the user identification module 115.

In addition, the SCAE module 120 mounted in the user identification module 115 processes a message according to a user input in the form of TCP / IP converted through the connector module 115 using a resource currently owned by the user. Determine whether you can. In this case, the SCAE module 102 may store in advance resources such as image information, content, and a submenu list for any upper menu, which are necessary for a site that the user frequently uses or accesses. And may be stored at 115.

Accordingly, when there is a corresponding resource corresponding to the user input, the SCAE module 120 may directly process the user input. For example, when a user inputs a web page execution command, content corresponding to the executed web page may be generated and displayed for the user to view based on a resource he has. In addition, when the user selects an arbitrary menu, the user has several levels of submenus in advance, such as submenus for the menu. Therefore, even if the user selects any of the submenus of the various levels, the user immediately brings up the submenu list of the selected menu. It can be displayed.

On the contrary, if the user's input cannot process user input, the resource is requested and provided to the external web server 130. In this case, the SCAE module 120 does not request the external web server 130 each time a resource required for processing a user input is required, but asynchronously prepares the external web server 130 in advance in case a resource is needed. Will be requested. For example, when the user selects a certain upper menu, the SCAE module 120 not only sub-menus that are resources for the upper menus that the user has, but also the predictable sub-menus of the upper menus in advance. 130 to secure. In this way, the resource can be requested asynchronously in advance in preparation for user input, thereby minimizing the delay of the user input processing.

In addition, the external web server 130 refers to a server in an external network such as an internet, an intranet, or the like that the terminal 105 and the user identification module 115 can access. The external web server 130 stores a resource for a web service used in the terminal 105, and then accesses the SCAE module 120 of the user identification module 115 that requires the resource in advance through a mobile communication network. If you do, it serves to provide resources for the service. At this time, the external web server 130 may obtain a resource for processing a user input from the information providing system 140 as needed. The information providing system 140 includes at least one of a database 145, a backend processing 150, and a legacy system 155. The database 145 refers to a set of data organized in a structure for receiving, storing, and supplying data in response to a request of a plurality of users, and the backend processing 150 performs frontend processing for directly interacting with users. In order to support indirectly, provide a resource close to a resource required by a user, or perform a function of communicating with a required resource. The legacy system 155 means those inherited from the past in programming languages, platform technologies, and the like.

2 is a diagram illustrating in detail the configuration of the terminal and the user identification module shown in FIG.

As shown in FIG. 2, in order to receive a web service from the terminal 105, a browser module 100 capable of accessing a wireless Internet service using a predetermined protocol and transmitting and receiving data should be installed. The browser module 100 receives a user input such as a web service request corresponding to a web service to be accessed as indicated by the reference numeral 200 through an initial browsing screen, and transmits a web service message and responds to the user input. Receive a response message to display the content for the executed web service.

Meanwhile, the connector module 110 is composed of a TCP / IP stack module 210 and an OMA Gateway module 220. The HTTP request, that is, the web service request from the browser module 100, is the TCP / IP of the connector module 110. It is delivered to the IP Stack module 210. The TCP / IP Stack module 210 then forwards the request to the OMA Gateway module 220 by protocol conversion.

The OMA Gateway module 220 is a gateway that can exchange information between a communication network compatible with the OMA standard specification and a communication network that is not. The OMA Gateway module 220 configures an application protocol data unit (APDU) according to a web service request from the terminal 105. In order to pass the script to the SCAE module 120 of the user identification module 115, the JavaScript is first passed to the Card Connector module 230. Then, the card connector module 230 delivers the JavaScript to the SCAE module 120, and the SCAE module 120 generates the content corresponding to the JavaScript request based on the resources it has. The APDU means a data packet unit for sending a command message or a response message through a smart card on which the SCAE module 120 is mounted. The generated content is delivered to the card connector module 230 in the form of HTTP and CSS data. The card connector module 230 constructs an APDU from the contents and delivers the APDU to the TCP / IP stack module 210 via the OMA Gateway 220. The browser module 100 receives the APDU, analyzes it, and displays the corresponding content to the user.

Hereinafter, referring to FIG. 3, a process of providing a web service using the AJAX method using a user identification module detached from a terminal in a wireless environment will be described. To this end, reference is made to FIG. 3, which is a signal flow diagram between components of a system for providing a web service according to an exemplary embodiment of the present invention.

First, in step 300, the browser module 100 determines whether there is a user input according to the use of a browser. As a result of the determination, if there is a user input, the browser module 100 transmits a resource request message for processing the user input to the OMA Gateway module 220 through the TCP / IP stack module 210 of the connector module 110. Then, the OMA Gateway module 220 configures the APDU in step 310 and transmits the JavaScript to the SCAE module 120 in step 315. Then, the SCAE module 120 checks the received JavaScript in step 320 and makes an HTTP request to the external web server 130 for an expected resource in advance, or asynchronously to secure necessary resources regardless of the JavaScript. You can request Accordingly, the external web server 130 checks in step 325 whether it can provide itself a resource corresponding to the HTTP request transmitted asynchronously from the SCAE module 120. If the web server 130 can support the resource corresponding to the HTTP request by itself, provide the corresponding resource in step 350 to generate content based on the additional resource. Otherwise, the information providing system 140 in step 330. In step 335, the corresponding resource is transmitted to the corresponding resource request, and the corresponding resource may be provided in step 350.

On the other hand, the SCAE module 120 received the JavaScript from the OMA Gateway 220 in step 315 and the SCAE module 120 in step 340 simultaneously with a series of processes to request the resource to the web server 130 asynchronously in advance. It determines whether the processing of the user input in the JavaScript itself is possible. That is, the SCAE module 120 determines whether the corresponding content can be generated in response to a web service request that is a user input. If the user input processing is possible, the SCAE module 120 generates content corresponding to the user input based on its own resource in step 345. Subsequently, in step 355, the content is configured as an APDU, and in step 360, the browser module requesting a corresponding resource via the OMA Gateway module 220 and the TCP / IP stack module 210 performs a response message composed of the APDU. 100). Accordingly, in step 360, the browser module 100 reads the content from the response message and displays the content on the screen for the user to view. If there is no resource for the user input processing request in step 340, the content is generated on the basis of additional resources asynchronously provided from the external web server 130 in steps 325 and 335 in step 350. The above-described steps 355, 360, and 365 are sequentially performed to display the corresponding content to the user.

As described above, the SCAE module 120 asynchronously acquires an expected resource and processes a user input itself.

As a result, according to an embodiment of the present invention, the SCAE module 120 does not directly receive the corresponding resource from the external web server 130 each time in response to user input such as frequently used content, or the like according to the user input pattern in advance. By having the latest resources and the like provided from the external web server 130 as necessary, the delay of user input processing can be minimized by reducing the impact of network traffic. In addition, the SCAE module 120 has its own resources for the user input to directly process the user's input without providing access to the external web server 130 to provide the web service, thereby improving the user's response speed Will be.

On the other hand, the operation in the SCAE module 120 will be described with a specific example as follows.

According to a preferred embodiment of the present invention, when the user selects a certain upper menu, the SCAE module 120 has a lower menu for the upper menu itself, and the lower menu of the lower menu is used as a sub menu. The submenu of SCAE module 120 may be obtained in advance from the external web server 130 and stored. Therefore, even if the user selects any of the submenus of the menu, the SCAE module 120 can immediately retrieve a list of the pre-stored submenus so that the display can be displayed on the screen immediately without a response delay. This allows the user to experience improved response speeds. In addition, according to an exemplary embodiment of the present invention, the SCAE module 20 satisfies any menu selection required by the user through a submenu that the SCAE module 20 has without communication with the web server 130 to provide a quick display. do.

As a result, the terminal 105 secures the necessary submenu in advance without the user having to simultaneously access a submenu for any menu selected by the user and a submenu for the submenu to an external web server to synchronously load a menu list. Multi-menu setting is possible, and delay due to transmission and reception between the browser interface of the terminal and the external web server can be minimized. Therefore, even if the user selects any menu among the submenus of the menu, the SCAE module 120 can immediately recall a list of the submenus stored in advance so that the screen can be displayed immediately without a response delay. This allows the user to experience improved response speeds.

Meanwhile, according to another preferred embodiment of the present invention, the SCAE module 20 may support a mobile game. In mobile games, where a game must be performed through several stages as a game progresses to perform a mission, when the user is performing a specific stage, information about some or all of the stages that the user can go to next may be previously displayed on an external web server. By importing, when a user actually goes to a particular stage, the game can be played on that stage without any delay. Therefore, the SCAE module 20 can obtain the corresponding data from the external web server 130 asynchronously with respect to the case where the user can input at any point in time, so that the user can respond in real time when the user actually makes a specific input. .

According to another preferred embodiment of the present invention, the SCAE module 120 may support mobile navigation. In general, mobile navigation should provide information about the location (traffic status, geographic information, business information, etc.) according to the location with the user. In this case, the SCAE module 120 obtains the location information for all or part of all possible cases of the user's location after a certain time in advance if the location is at any point in time, thereby allowing the user to actually specify the specific information. When you go to a location, you can provide information in real time.

 In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, in the foregoing description, a case of supporting a multi-menu, mobile game, and mobile navigation has been described as an example. However, the embodiment of the present invention is not limited thereto, and may be applied to various cases. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

According to the present invention as described above, to provide a web service, without receiving an external web server each time, asynchronously receives data from an external web server, and immediately receives user input, thereby reducing network traffic by processing itself by the user identification module. Not only can it be expected, it also has the advantage of improving user response speed.
