The present invention relates to a system including a mobile communication terminal and a control method thereof, and more particularly, to a content usage restriction system and a control method according to the rate plan of the mobile communication terminal.

In general, the mobile communication terminal is mainly intended for voice communication, but has been improved to enable various data communication due to a user's demand for using the mobile communication terminal.

In particular, due to the activation of the Internet in a wired communication network, a function for enabling the Internet to be used in a wireless communication network using a mobile communication terminal has been added.

The Internet (INTERNET) is the world's largest computer communication network originated from ARPANET, originally developed for military purposes, and is based on the TCP / IP protocol. Services available on the Internet include e-mail, remote computer connection (telnet), file transfer (FTP), Usenet News, Internet information search (Gopher), Internet conversation and discussion ( IRC), electronic bulletin boards (BBS), hypertext information browsing (WWW: World Wide Web), online games, and so on. Nowadays, with the rapid increase of web sites, viewing of web pages has become the main use of the Internet.

As such, the function of the mobile communication terminal has been improved to enable the Internet, among other things, to view web pages, and the number of users using the Internet using the mobile communication terminal is increasing.

However, wireless networks using mobile communication terminals have a higher network load depending on the amount of data transmitted and received compared to wired networks. come.

For example, there is no monthly fee system that can be selected when using a wired Internet network in the Internet usage plan using a mobile communication terminal. Here, the monthly fee plan refers to a plan that can be used unlimitedly regardless of the Internet usage time and transmission / reception data capacity if the carrier pays only a predetermined amount fixed on a monthly basis.

As such, due to the characteristics of the wireless network, the Internet usage plan of the mobile communication terminal provided by the mobile communication company is limited to a fee that is mainly charged according to the packet transmission amount. have.

The present invention has been made to solve the above-described problems, the purpose of which is to limit the use of the content according to the rate plan of the mobile communication terminal to limit the use of the predetermined content in accordance with various charge policies when using the Internet using the mobile communication terminal It is to provide a system and a control method thereof.

Another object of the present invention is to provide a system for limiting content usage according to a rate plan of a mobile communication terminal and a method of controlling the same, so that a content limitation process can be quickly performed according to a rate plan selected by a user of a mobile communication terminal.

In order to achieve the above object, a content usage restriction system according to a rate plan of a mobile communication terminal according to the present invention includes a mobile communication terminal; A markup page providing server including a markup page written in a markup language and transmitting a markup page response signal including a markup page according to a markup page request signal; And a relay server positioned between a communication path between the mobile communication terminal and the markup page providing server, wherein the relay server receives the markup page request signal from the mobile communication terminal and performs authentication through the authentication process. Extracting content usage restriction information of the terminal, requesting the markup page providing server to transmit a markup page, and receiving the markup page response signal from the markup page providing server, responding to the markup page response signal. Add content usage restriction information, and transmit a markup page response signal including content usage restriction information to the mobile communication terminal, and the mobile communication terminal responds to a markup page response when a markup page response signal is received from the relay server. Use according to content usage restrictions contained in the signal To limit the use of the specific content of the markup page by the features.

In addition, between the mobile communication terminal according to the present invention, a markup page providing server having a markup page written in a markup language, and the mobile communication terminal and the markup page providing server communication path. A control method of a content usage restriction system according to a rate plan of a mobile communication terminal including a relay server located at the mobile terminal includes: requesting a markup page from the mobile communication terminal; When the relay server receives a markup page request from the mobile communication terminal, extracting content use restriction information of the mobile communication terminal through an authentication process, and requesting the markup page providing server to transmit a markup page; ; Transmitting, by the markup page providing server, a markup page response signal including a corresponding markup page to the relay server according to a markup page transmission request of the relay server; When the markup page response signal is received from the markup page providing server, the content use restriction information is added to the markup page response signal, and the markup page response signal including the content use restriction information is transmitted to the mobile communication terminal. It comprises a step.

As described above, according to the present invention, the mobile communication company may provide various types of plans that can be selected by the user of the mobile communication terminal.

In addition, the mobile communication terminal can easily limit the use of some of the content included in the web page according to the rate plan selected by the user, or can easily inform the user of the content use restriction message.

In particular, since the content usage restriction information is included in the header information of the communication protocol and transmitted to the mobile communication terminal, additional packets related to user authentication such as content usage restriction are not generated, thereby improving the overall speed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the content usage restriction system of the mobile communication terminal 10 according to an embodiment of the present invention includes a mobile communication terminal 10, a relay server 20, and a markup page providing server 50. It is configured to include). In addition, the content usage restriction system according to the rate plan of FIG. 1 may further include an authentication server 30 and a content conversion server 40.

The markup page providing server 50 may be a kind of web server provided in the Internet network 90 as a server providing a markup page written in a markup language. Although there are many types of markup languages, in the present embodiment, the markup page providing server 50 provides a web page written in HyperText Markup Language (HTML) using HTTP (HyperText Transfer Protocol). Let's do it.

The markup page providing server 50 stores a markup page. When the markup page providing server 50 receives a signal requesting a markup page, the markup page providing server 50 generates and transmits a markup page response signal.

At this time, the markup page providing server 50 includes markup data corresponding to the requested markup page and header data including predetermined configuration information in the markup page response signal.

Here, the markup data corresponds to data constituting the markup page and may include, for example, all data between the <html> tag and the </ html> tag.

In addition, the header data includes predetermined information, which includes a server type, a content-length, a data type, a content-type, a setting language, and a connection state. , Date, etc. may be included. The header data functions to provide predetermined information related to the markup page to a browser of a terminal that receives the markup page response signal.

That is, in the transmission and reception of markup data, header data including predetermined information on the markup page and other connection states, etc. are further required in addition to the markup page actually seen in the terminal browser or the like.

 Even with reference to the known HyperText Transfer Protocol (HTTP), it can be seen that the header data and the markup data corresponding to the actual markup page are distinguished from each other.

The relay server 20 is located between the communication path of the mobile communication terminal 10 and the markup page providing server. As shown in the figure, the relay server 20 may be provided in the mobile communication network 70, but may also be provided in the internet network 90, such as a markup page providing server.

When the relay server 20 receives the markup page request signal from the mobile communication terminal 10, the relay server 20 requests the markup page providing server 50 to transmit a corresponding markup page. When the markup page response signal is received from the markup page providing server 50, the relay server 20 adds content usage restriction information of the mobile communication terminal 10 to the header data included in the markup page response signal. The markup page response signal to which the content usage restriction information is added is transmitted to the mobile communication terminal 10.

In this case, the relay server 20 may request and receive the content usage restriction information of the mobile communication terminal 10 from the authentication server 30, or, if a self database related to user authentication is established, the mobile communication from the database. Although content usage restriction information of the terminal 10 may be extracted, in this embodiment, the use of the authentication server 30 will be described as an example.

The authentication server 30 is a server that includes various types of authority information of the mobile communication terminal 10, and particularly includes content usage restriction information.

An example of content usage restriction information stored in the authentication server 30 is shown in FIG. 2.

As shown in the figure, the content usage restriction information stored in the authentication server 30 includes each mobile communication terminal 10 phone number, the type of content prohibited by the corresponding mobile communication terminal 10, and video playback restriction. Time and the like.

Such content use restriction information may be changed in various ways in connection with a rate plan selected when a user of the mobile communication terminal 10 applies for subscription to a mobile communication company.

When the content conversion server 40 is requested to transmit predetermined content from the mobile communication terminal 10, the content conversion server 40 receives a requested content from the markup page providing server 50 and delivers the requested content to the mobile communication terminal 10. To perform. In this case, the content conversion server 40 may change the content in a form executable in the mobile communication terminal 10 and limit the content transmission time through communication with the authentication server 30.

That is, various types of content may be connected to a markup page (eg, a web page) provided by the markup page providing server 50. For example, it is assumed that the domain address of the markup page is aaa.bbb. In this case, a markup tag such as "<a href=http://aaa.bbb/test.mpg>" may be used to include predetermined content (here, test.mpg) in the markup page.

The user of the mobile communication terminal 10 may request the transmission of test.mpg to the markup page providing server 50 having a domain of aaa.bbb by selecting such a connection (link).

In this case, the content conversion server 40 receives the test.mpg file from the markup page providing server 50 and converts the test.mpg file into a real-time stream format executable by the mobile communication terminal 10 and transmits it to the mobile communication terminal 10. The transmission time is based on the content usage restriction information of the mobile communication terminal 10 as described above.

Referring to FIG. 2, when the mobile number of the mobile communication terminal 10 is "010-1111-1111", since the video playback time limit is 3 minutes, the content conversion server 40 converts a real time stream of test.mpg. It transmits to the mobile communication terminal 10 only for 3 minutes.

The mobile communication terminal 10 is a portable communication device including a mobile phone, personal digital assistants (PDAs), and the like. The markup page providing server 50 of the Internet network 90 is connected to the mobile communication network 70 through the base station 60. ) Can be communicated with. A router 80 may be provided between the mobile communication network and the internet network.

The mobile communication terminal 10 requests the transmission of the markup page according to a user's request. When the markup page response signal is received from the relay server 20, the mobile terminal 10 interprets the markup data included in the markup page response signal and marks it. Display the up page. At this time, the mobile communication terminal 10 limits the user's use of the predetermined content included in the displayed markup page based on the content usage restriction information included in the header data of the received markup page response signal.

For example, if certain content is linked by a hyperlink, change the hyperlink to inactive to prevent the user from requesting the link, or if the user requests a hyperlink, You can also notify the user by popping up information about usage restrictions. In this case, the user may press the confirmation button after reading the usage restriction content so that the corresponding content may be received.

As described above, the mobile communication terminal 10 imposes the above predetermined restrictions on the use of the predetermined contents included in the markup page of the user, which is added to the header data of the markup page response signal by the relay server 20. It is based on usage restriction information.

Hereinafter, a control flow of a content usage restriction system according to a rate plan of a mobile communication terminal 10 according to an embodiment of the present invention will be described with reference to FIG. 3. In the description of this embodiment, the markup page providing server 50 is an example of providing a web page.

First, when a mobile terminal user requests a predetermined web page by pressing a wireless Internet connection key (not shown) or the like, the mobile terminal 10 transmits a web page request signal to the relay server 20 (step). S1).

The relay server 20 first requests authentication of the mobile communication terminal 10 from the authentication server 30 (step S3), and the authentication server 30 restricts content usage of the corresponding mobile communication terminal 10. Is transmitted to the relay server 20 (step S5).

The above process of the relay server 20 may be performed every time a web page request signal is received from the mobile communication terminal 10, but preferably, only when the first web page request is received from the mobile communication terminal 10. Can be.

Here, the "first request" means the first web page request made whenever the mobile communication terminal 10 connects to the wireless Internet. For example, after terminating the wireless Internet function of the mobile communication terminal 10 after web surfing, when the wireless Internet is connected again, the first request from the mobile communication terminal 10 is generated again.

On the other hand, the relay server 20 receiving the content usage restriction information requests the web server to transmit the web page requested from the mobile communication terminal 10 (step S7).

The web server, which has been requested to transmit a web page from the relay server 20, transmits a web page response signal to the relay server 20 (step S9). In this case, the web page response signal includes web data corresponding to the web page and a predetermined value. Header data including setting information and the like is included.

The relay server 20 receiving the web page response signal from the web server adds the content usage restriction information received from the authentication server 30 to the header data of the web page response signal (step S11), and sends the web page response signal. Transmit to mobile communication terminal 10 (step S13).

For example, in the case of sending and receiving a web page using HTTP, the relay server 20 adds content such as "HTTP-X-LGT-SERVICE-INFO = Browising: 0, Streaming: 3, Download: 5" to the HTTP header. can do. Here, 'Browising: 0' means that there is no limit when browsing the web, 'Streaming: 3' means that video streaming is limited to 3 minutes, and 'Download: 5' means that downloading is only possible up to 5 megabytes. This additional header information can be variously changed by appointment.

The mobile communication terminal 10 interprets and displays web data included in the web page response signal (step S15). That is, in this step, a web page provided by the web server is displayed on the display unit of the mobile communication terminal 10.

The user of the mobile communication terminal 10 may select predetermined content included in a web page displayed on the mobile communication terminal 10, for example, as a hyperlink such as <a href=aaa.bbb/test.mpeg>. You can select (click) the linked content.

At this time, the mobile communication terminal 10 determines whether the content selected by the user is content whose use is restricted based on the content use restriction information (step S17). Here, whether the content selected by the user is a content whose use is restricted may be determined by a method of comparing the extension of the content. For example, since the extension of test.mpeg is "mpeg", the mobile communication terminal 10 determines that the format of the corresponding content is the MPEG (Moving Picture Experts Group) format, and the video including the mpeg format in the content usage restriction information. If there is restriction information on, it may be determined that the content of test.mpeg is restricted content.

Since the format of the content based on the extension may not be accurate, the MIME (Multipurpose Internet Mail Extensions) type for the content may be received and determined from the web server through the content conversion server 40 in advance.

Since a process of requesting and receiving a MIME type of a specific file is a known technique, a detailed description thereof will be omitted.

When the restricted content is selected by the user (step S17), for example, when a mobile terminal user whose video usage is limited to 3 minutes clicks a video link included in a webpage as shown in FIG. 4 (a), The mobile communication terminal 10 generates a content usage restriction message (for example, a service usage restriction message) and displays the popup window as shown in FIG. 4 (b) (step S19).

A specific example of the content usage restriction message is shown in FIG. 4 (b2).

Referring to the figure, it can be seen that the playback of the corresponding video is limited to 3 minutes unless the user changes the plan.

When the user who confirms the message of the pop-up window as shown in FIG. 4 (b2) and presses a confirmation key (Yes key), the mobile communication terminal 10 requests content from the content conversion server 40 (step S21).

The content conversion server 40 requests the authentication server 30 to authenticate the mobile communication terminal 10 (step S23), and the authentication server 30 restricts the content use of the corresponding mobile communication terminal 10. Is transmitted (step S25).

Subsequently, the content conversion server 40 requests the web server (aaa.bbb) 50 to transmit the content (test.mpeg) (step S27), and when the content is received from the web server 50 (step S29). Transfer to mobile communication terminal 10 (step S31). In this case, the content conversion server 40 may convert the content received from the web server 50 into a real time stream and transmit the content to the mobile communication terminal 10 only for a period of time (eg, 3 minutes) according to the content restriction information. (Step S35).

When the content is received from the content conversion server 40, the mobile communication terminal 10 executes as shown in FIG. 4 (c) (step S33), and after the content transmission from the content conversion server 40 is terminated. As shown in Fig. 4D, the display returns to the original web page display screen (step S39).

In the above embodiment, the mobile communication terminal 10 restricts the use of the content by the user. When the restricted content is selected, the mobile terminal 10 displays the usage restriction information of the corresponding content in a pop-up window, and the user presses a confirmation key. In this case, a method of executing the corresponding content in a state where the playing time is limited is described as an example. However, the execution of the corresponding content may be previously limited on the mobile communication terminal 10.

For example, the limited use included in web pages can disable the link itself for content. The web page displayed on the mobile communication terminal 10 is changed according to a plan subscribed to a mobile carrier, and whether or not to activate / deactivate predetermined content depends on whether the member is a member of a conventional web server. This is different from what is determined in. That is, according to the plan, the specific content of the web page received from the web server is made inactive so that the user cannot select it.

On the other hand, the present invention is not limited to the above specific embodiments, but can be modified and modified in various ways without departing from the gist of the present invention. In particular, the restriction of use for a predetermined content among the contents of the markup page on the mobile communication terminal can be variously modified based on the above-described embodiments.

In addition, in the above-described embodiment, the function of the content conversion server has been described based on the video, but the content conversion server may change various types of data such as document data and multimedia data into a format that can be processed by the mobile communication terminal.

It will be apparent that such variations and modifications are included in the present invention as long as they belong to the appended claims.
