The information providing center (AMP) 5 determines whether it is an information providing service or an Internet homepage file acquisition from the user request, performs a process for transferring the user request according to the route information, and then the dialogue (session) is performed. This is the part that monitors the state until the end. The registered user database 6 includes information on registered users, information on user-specific clipping settings referred to by the received message processing unit 12 for file acquisition, and information on user-specific cookie settings, as will be described in detail later. This is a part for recording information for the user and information for setting bookmark registration for each user.
[0021]
The gateway 9 is arranged between the mobile communication network 8 and the Internet 31, and receives a message from one network, stores it if necessary, and converts the protocol in order to ensure consistency of connection between different networks. It is a part to be transmitted to the other network, and is composed of a web gateway platform (hereinafter referred to as WGP: Web Gateway Platform) 10 as a main part of the present invention and a proxy server 30 as a firewall.
[0022]
The WGP 10 receives the file acquisition request transmitted from the information providing center (AMP) 5 side of the mobile communication network 8 and receives the file acquisition request from the mobile unit 1 based on the acquisition request from the reception unit 11. A received message processing unit 12 for recording a history set for each file and performing transmission processing for file acquisition, and a received message processing table for referring to or recording for processing in the received message processing unit 12 13, a proxy client unit 14 that transmits an acquisition request from the received message processing unit 12 to the proxy server 30 and receives an HTML file acquired from the web server 32 of the Internet 31 by the proxy server 30, and the proxy client unit Simplified transfer that mobile device 1 can display 14 acquired files A filter unit 14 for conversion to machine markup language (MML), a setting / definition unit 16 for performing setting / definition for processing of the filter unit 15, and a received message processing unit 12 are linked.

When receiving a file acquisition request from the information providing center (AMP) 5, the reception unit 11 transmits this acquisition request to the reception message processing unit 12.
[0024]
The received message processing table 13 relates to the session information table and history table written or referenced for each mobile device number, and activation / deactivation (on / off) of a cookie function set individually for each mobile device number. It consists of a user-specific cookie setting table that stores information, a user information table that stores information related to a user cut-out function, which will be described in detail later, and the like. Here, one example of the cookie function is that some homepages on the Internet require user registration / authentication. The browser remembers that a cookie was given to the registered user and received from the homepage, and the same next time When accessing the homepage, user authentication is performed based on cookies. In this case, there is no need to newly enter a password or the like. In the present embodiment, for example, the cookie function is activated / stopped on the “cookie setting” page in the service homepage so that the same cookie function can be used when browsing the homepage from the mobile device 1. It can be set. This setting information is stored in the registered user database 6, and when the cookie is activated, the cookie information is stored and managed together with the address of the homepage on behalf of the mobile device 1. When accessing the same homepage next time, the WGP 10 refers to the registered user database 6 by referring to the address and the mobile device number transmitted from the mobile device 1 stored in the table, and accesses the cookie information. It is like that. Information such as the history table of the received message processing table 13 can be periodically deleted by batch processing.
[0025]
The reception message processing unit 12 receives the acquisition request from the reception unit 11, writes the session information constituting the reception message processing table 13 into the session information table, and sets the designated address for each mobile unit number. Write to the history table, refer to the link table 17 to determine whether the address of the acquisition request from the mobile device 1 is an absolute address or a relative address, and refer to the information on start / stop stored in the cookie setting table for each user Further, by referring to the user cut-out information stored in the user information table, the processing for the acquisition request is performed and transmitted to the proxy client unit 14.
[0026]
The proxy client unit 14 receives the acquisition request transmitted from the received message processing unit 12 and transmits the acquisition request to the proxy server 30 with reference to the user-specific cookie setting information and session information. Based on the acquisition request transmitted from the proxy client unit 14, the proxy server 30 acquires a home page file in the web server 32 at a specified address on the Internet 31, and sends the acquired file to the proxy client unit 14. Send. This acquisition file is described in HTML or MML. The proxy client unit 14 transmits the acquired file to the filter unit 15 based on the conversion start request from the received message processing unit 12.
[0027]
The filter unit 15 performs conversion processing based on a setting / definition unit 16 that performs filter setting, definition for conversion between HTML and MML, or definition of a mask target.
[0028]
FIG. 3 is a flowchart showing the processing procedure of the filter unit. When the proxy client unit 14 acquires a file and receives a filter processing start message in response to an instruction from the received message processing unit 12 (ST1), first, Japanese code conversion is performed. After performing frame control processing (ST3), the acquired file described in HTML is converted into a corresponding file described in MML, and when it is described in MML, conversion is performed. Leave as it is (ST4). This MML is proposed by the applicant in the information providing service system and is described in detail. The setting / definition unit 16 is a shortened portion where efficiency is increased by shortening the HTML in order to reduce the amount of data. Defines an MML corresponding to HTML, and when it is not defined, deletes it at the time of conversion. Next, when a link extension that does not correspond to the converted file described in the MML is included, mask processing of a keyword that does not correspond to the mask target definition defined in the setting / definition unit 16 is performed. (ST5).
[0029]
FIG. 4 is a diagram showing an extension table when mask processing is performed. For example, the extensions .html and htm are HTML documents and the corresponding extensions, but the extension is .txt. , .Ps, .au, .gif, etc. are file types of ASC / text, postscript, audio, GIF image, etc., and are unsupported extensions. In the above mask processing, if there is a link with an extension that does not correspond in the acquired file, the link itself is ignored, and if there is a character string indicating the contents of the link destination, only that is extracted. Display, and do not implement unsupported extensions. For example, if the file to be masked is
<AH = http: //www.sky-web.org/index.html> Sky-Web homepage </A>
<AH = http: //www.sky-web.org/index.img/SkyWeb1.gif> Sky-Web image 1 </A>
<AH = http: //www.tdp.co.jp> TDP homepage </A>
In this case, after mask processing,
<AH = http: //www.sky-web.org/index.html> Sky-Web homepage </A>
Sky-Web image 1
<AH = http: //www.tdp.co.jp> TDP homepage </A>
become that way. In this way, image display and the like that cannot be handled on the mobile device 1 side is limited by mask processing, and if there is a character string, only that can be displayed.
[0030]
Next, as shown in FIG. 3, when there is link information in the acquired file after the mask process, a link table creation process is performed to write the absolute address to the link table 17 (ST6). As described above, the received message processing unit 12 determines whether the acquisition request from the mobile device 1 side is an absolute address or a relative address. For example, in the case of a relative address such as L001, the link table 17 uses this L001. For example, in the filter unit 15, if there is link information in the acquisition file, the absolute address is linked to the link table 17. Register with. In this case, a relative address that is unique is assigned. For example,
Relative address Absolute address
L000 http://aaa.co.jp
L001 http://bbb.co.jp
L002 http://ccc.co.jp
Write like this. Next, the processing message is transmitted to the transmission message processing unit 18 under the instruction of the reception message processing unit 12 (ST7).
[0031]
The transmission message processing table 19 is a table of session information, history, user information, etc. for each mobile device that is referred to by the transmission message processing unit 18 for division processing.
[0032]
The transmission message processing unit 18 divides the processing message converted by the filter unit 15 into a package, assigns a unique address to the package, and inserts a tag as necessary. This package is processed within 384 bytes including, for example, three concatenated 128 bytes, which is a capacity that can be transferred on the mobile communication network 8 side including the tag.
[0033]
FIG. 5 is a diagram for explaining the division processing in WGP and the display in the mobile device. For example, when the processing message after conversion is 2304 bytes, it is divided into six packages, but each has a unique H = 1. , H = 2,..., And the <next> tag indicating that the message is in the WGP 10 is inserted in the first package. The <next> tag contains the unique address H = 2 of the package 2. When the <next> tag is selected on the mobile device 1, the WGP 10 side transmits the package 2. The package 2 includes a <next> tag including the address H = 3 of the package 3 to indicate that the message is continuing, and an address H = 1 of the package 1 for selecting the package 1 transmitted first. <Previous> tag is inserted. Similarly, tags are inserted up to the last package.
[0034]
FIG. 6 is a diagram for explaining the processing when the home page is divided into frames and the display of the mobile device. When the home page of the acquired file is divided into frames on the left and right, for example, the filter unit 15 A control process is performed (ST3), the WGP 10 side transmits to the mobile device 1 side that it is divided into frames, the address of each frame is edited and displayed, the frame selection process is performed, and the mobile device 1 side is selected. The result is transmitted to the WGP 10 again.
[0035]
The transmission message processing unit 18 writes the address of the link destination home page in the history table and returns to the link source page when the filter unit 15 includes a valid link after performing the mask process, The process which shows that it continues is performed. Further, in the case of a package corresponding to an address for bookmark registration, a <registration> tag is inserted into the first 384 bytes of the package. If character cutout is set, the designated keyword is searched for when dividing into 384-byte packages. If the number of skips is set, the same keyword is skipped the set number of times, and if there is a specified keyword, the information is divided into 384 bytes starting from the specified keyword, and <previous>, < Insert a tag such as after>.
[0036]
FIG. 7 is a diagram for explaining processing when there is a valid link in WGP and display on the mobile device. A valid link is included in the package N on the WGP 10 side, its address is recorded in the history table, and the package N When the link keyword is selected by the mobile device 1, the WGP 10 refers to the link table 17 to obtain the link destination message, and the mobile device 1 receives the link destination as described above. Process so that it can be displayed. Then, the address of the link destination homepage is written in the history table, and the <return> tag for returning to the link source in the package 1, 2,...
[0037]
  FIG. 8 is a diagram for explaining processing in the case of bookmark registration. In general, when searching the Internet from a personal computer, so-called bookmark registration can be performed, but any home page can also be registered when searching for the Internet by the mobile device 1. That is, the address of the Internet homepage is transmitted from the mobile device 1 side, the homepage of the designated address is fetched, the above-described processing is performed, and <registration> together with the <next> tag in the first 384 bytes of package 1 A tag is inserted and transmitted to the mobile device 1 side. When the mobile device 1 selects this <Register> tag,WGP10 isSeparate addresses in the built-in history table for each mobile device numberAs a bookmarksave.IeWhen the <Register> tag is selected, the WGP 10 displays the designated address on the screen of the mobile device 1 and confirms whether or not registration is possible. The bookmarked address is saved even after the session is disconnected.Registered user database 6To be saved. The mobile device 1 can select a bookmark added to the menu from the next time and select a registered address to obtain a message on the home page of the same address.
[0038]
FIG. 9 is a diagram for explaining character cutout setting, its processing, and display on the mobile device. Since the amount of information that can be displayed at one time by the mobile device 1 is limited, depending on the homepage, it may be necessary to turn the page many times before reaching the desired location. From the personal computer side, access the web screen dedicated to the service, and enter the address of the frequently viewed homepage, the keyword contained in that part, and how many times the same keyword is skipped. For example, as shown in FIG. 9, when the address: http://www.tdp.co.jp. Is set as the keyword: the latest information, and the number of skips: 2, this setting information Are stored and managed in the registered user database 6 for each telephone number which is a mobile device number. When the mobile device 1 accesses the corresponding home page next time, after the WGP 10 performs processing by the filter unit 15 as described above, the transmission message processing unit 18 first searches for a designated keyword when dividing the package into 384 byte packages, If the skip count is set, the same keyword is skipped the set number of times. If there is a designated keyword, it is divided into 384 bytes starting from the designated keyword, and tags such as <previous> tag and <next> tag are inserted as necessary. That is, in the character cutout setting described above, the keyword: the latest information is searched for on the homepage of the address: http://www.tdp.co.jp. The number of skips: skipped twice: the third is selected, and the latest information Is divided into 384 bytes, and the <previous> tag and the <next> tag are inserted. If the designated keyword does not exist due to the modification of the home page, the transmission message processing unit 19 displays only the <previous> without displaying the target home page. Process to display.
[0039]
According to the above configuration, the present invention inputs an address from the mobile device 1 of the mobile communication network 8 having a message communication function, transmits the address to the gateway 9, and performs processing for file acquisition by the WGP 10 of the gateway 9. A file described in HTML and MML at a specified address via the proxy server 30 is acquired, and the acquired HTML file is converted into a simplified MML that can be displayed by the mobile device 1 by the filter unit 15 of the WGP 10, or A process including deleting a link including an unsupported extension is performed, and the processed file is divided by the transmission message processing unit 18 according to the display capacity on the mobile device 1 side and transmitted to the mobile communication network 8. Therefore, it is possible to support the display unit of the mobile device 1 without making any changes to the home page created on the conventional website. That capacity and the home page in the configuration can be made to the message display. In addition, in the present invention, bookmark registration for searching the Internet enables bookmark registration similar to that of a personal computer, and by setting character extraction as user information, pages can be accessed many times. You can easily reach the page you want to see without sending. When the home page is created in MML, it can be displayed on the mobile device 1 as it is by designating an address.
[0040]
In the above embodiment, the example in which the short message service is used for the bearer and the transmission data amount is divided into 384 bytes has been described.
