Some hyperlinks for converting from an ML document to another HTML document are all converted, while others are not converted at all. However, for web-based mobile phone terminals, while improving the usability of users, it is also necessary to separate confidential information and protect copyrights between intranet users (members of the organization) and Internet users (outside the organization). From the viewpoint, there is a problem that flexibility in selecting a hierarchy to which a hyperlink can be appropriately selected is poor.

[0006] Further, there is a case where a Web service for a mobile phone is connected to an existing authentication system for a WWW browser for user authentication. However, the user has a complicated identification code ID specified or set by the administrator.
Or password. Web for mobile phones
In the service, a user needs to input a complicated identification code ID and a password from a Web mobile phone terminal by a special method before starting to use the mobile phone Web service. However, in the case of a web-based mobile phone terminal, the number input is one.
Although it can be done with a single keystroke, it is necessary to enter the key several times with English characters, katakana, and hiragana, and there is a problem that the operation is complicated and the user's convenience is greatly reduced as compared with a WWW browser. Was.

The present invention solves the above-mentioned problems, and
The first purpose is to convert existing HTML documents into Web documents.
It is an object of the present invention to provide a mobile intranet system for converting into a compact HTML document for mobile phone terminals for b. A second object is to provide a mobile intranet system in which an identification code ID and a password input from a Web mobile phone terminal can be easily input before starting to use the Web service for mobile phones.

[0010] Preferably, as set forth in claim 2, We
The document conversion means for a mobile phone terminal for b divides the HTML document within a predetermined data amount range, and the web mobile phone terminal converts the converted HT when displaying information.
It is preferable to have a function of displaying an ML document. In a mobile intranet system, when a user browses information using a Web mobile phone terminal, the document capacity that can be displayed on one page of a file is limited to, for example, 5 kilobytes due to restrictions of the Web mobile phone terminal system. On the other hand, existing WWW
The HTML document prepared in the server basically has an arbitrary capacity, and there are many HTML documents exceeding the allowable capacity of the Web-based mobile phone terminal system. Therefore, the mobile intranet system automatically divides an HTML document acquired with a data amount set in advance by the system administrator, for example, the number of lines, when displaying information on the Web mobile phone terminal,

Japanese kanji codes for Web mobile phone terminals are limited to, for example, Shift JIS HTML documents. Therefore,
The mobile intranet system automatically analyzes the kanji code of the HTML document acquired at the time of displaying the information on the Web mobile phone terminal, and converts the kanji code into shift JIS.

[0014] In addition, the document conversion means for the Web mobile phone terminal changes the meta tag defining the document form of the HTML document and shifts the kanji code information contained in the meta tag to JI.
It is preferable to provide a function to correct for S. More preferably, the document conversion means for a Web mobile phone terminal is HTML
After optimizing the tags used in the document, it is preferable to have a function of converting the tag into a document layout display optimized for browsing from a Web mobile phone terminal. Web mobile phone terminals are limited in screen size and displayable tags (instruction commands) used in Compact HTML documents, so it is useful to be able to check the document layout after conversion in advance. It is.

Preferably, the means for acquiring the hyperlinked HTML document (a mechanism for moving from an HTML document to another HTML document) is provided by the WWW.
If the configuration is such that the HTML document is acquired within the range of the HTML document stored in the server, the mobile intranet system automatically acquires the HTML document from the conversion destination WWW server. Further, the mobile intranet system prohibits the acquisition of HTML documents other than the WWW server specified by the administrator. As a result, the administrator can automatically limit the HTML documents to be viewed by the user on the Web mobile phone terminal. Then, when the HTML document creator holds an HTML document that he does not want to be viewed on the Web mobile phone terminal, the administrator does not specify the corresponding document, thereby infringing the copyright of the HTML document creator. Can be prevented. Also, the mobile intranet system
By setting a plurality of acquisition source WWW servers, the user can freely browse the acquired WWW servers with the Web mobile phone terminal.

Preferably, if the title of the WWW server to be acquired is specified in advance, it is possible to freely add or delete the acquired HTML document without any knowledge of creating the HTML document. Further, the display procedure may be configured such that a weight can be set for each title and the display order can be controlled. More preferably, when an HTML document creator creates an important HTML document and publishes it to a Web mobile phone terminal, the HTML document creator is required to prevent the HTML document from being converted in a manner that does not conform to the intention of the HTML document creator. It is preferable to provide a function for confirming how the HTML document is converted.

The mobile intranet system according to claim 8 which achieves the second object, as shown in FIG.
In a mobile intranet system that acquires Web information stored in the Web-based mobile phone terminal server 15 using the Web-based mobile phone terminal 31, a member management unit that pre-registers users of the Web-based mobile phone terminal server 158, and a member authentication unit 159 for authenticating the user registered in the member management unit using the identification code, and inputting the authentication code using the operation key of the web-based mobile phone terminal 31; When the authentication code thus entered matches the authentication code registered in the member authentication means 159, access from the Web mobile phone terminal 31 to the Web mobile phone terminal server 15 is authorized.

With such a configuration, an authentication function is provided to make the information of the intranet in the organization using the Web mobile phone terminal server 15 available to only a specific user. For the member authentication means 159, for example, UN
In IX (registered trademark), it is preferable to use the / etc / passwd method (a standard authentication method of UNIX), RADIUS (a system for performing authentication at the time of remote access by dial-up), and a communication method to an authentication server using a socket. Preferably, in a password used as an authentication code, a password input method of inputting four or more half-width numeric characters may be adopted in order to save trouble of inputting complicated alphanumeric characters. For the operation key input of the web-based mobile phone terminal 31, half-width numbers can be easily input due to restrictions of the web-based mobile phone terminal system. However, it is difficult to input characters that are more complicated than numbers such as hiragana and katakana. This is because a lot of trouble is required.

Preferably, as described in claim 9, user registration in the member management means 158 or the member authentication means 1
It is preferable that the registration of the identification code into 59 is performed by a user using a WWW browser. In the mobile intranet system of the present invention, it is possible to communicate with an existing authentication server on an intranet of an organization or the like to share authentication information. In this case, in order to avoid complicated character input due to operation key input of the web-based mobile phone terminal 31, a process of setting a password using a WWW browser is performed in advance. Preferably, the personal identification number is for the mobile phone terminal 31 for the Web, and is managed independently of the password provided for the WWW browser. As a result, it is possible to manage the Web mobile phone terminal user with an independent password, which is not used in the existing authentication server for the WWW browser, and it is possible to duplicate security and prevent information leakage. It is possible.

Preferably, as described in claim 10, the UR in which the identification code to the member authentication means 159 is registered in advance.
The L address is distributed to the mobile phone terminal 31 for Web, and
It is preferable that the mobile phone terminal 31 for b access the distributed URL address and authenticate the member authentication unit 159 without re-entering the identification code. With this configuration, the mobile intranet system is accessed in advance by the WWW browser, the member authentication registration is completed, and the ID information is transmitted by e-mail to the e-mail address of the Web mobile phone terminal owned by the user. The user can access the authentication screen in which the identification code ID has been entered simply by opening the transmitted mail and selecting a special Internet address included in the mail. This eliminates the need for the user to input a complicated identification code ID from the Web mobile phone terminal, and can access the information on the top page of the organization and the intranet by inputting only a preset password. Therefore, the input of the complicated identification code ID and password can be reduced to one time at the time of the initial registration, and the convenience for the user is improved.

Preferably, as described in claim 11, W
The eb mobile phone terminal may be configured to store the distributed URL address in the web mobile phone terminal so that it can be called at any time. According to such a configuration,
By storing the information at the time of member authentication registration in the URL address, it is possible to use the bookmark function of the Web mobile phone terminal to access the member-specific URL address. Then, it is not necessary to input the authentication code required for the member authentication using the web-based mobile phone terminal, and the security management can be reliably performed while ensuring the convenience of the user.

Further, a server 15 for a mobile phone terminal for Web
The content for Web mobile phone terminals stored in
In order to enable browsing with a WW browser, it is preferable to use an HTTP cookie to perform session management when accessing from a device other than the Web mobile phone terminal. Here, the HTTP cookie is a program that is transmitted and received in a frozen state, and that operates on a Web-based mobile phone terminal when decompressed. In this way, when accessing with a WWW browser, it is preferable to always input the identification code ID and the personal identification number to perform the member authentication. Then, on the side of the web-based mobile phone terminal server 15, the Web
It is possible to distinguish the access from the mobile phone terminal for b and the WWW browser and maintain the security level.
Even if an attempt is made to access intranet information for members without going through the authentication process with the WWW browser, the HTTP cooki stored in the WWW browser on the system side is used.
The authentication information stored in e and the authentication information included in the URL are compared, and if they do not match, browsing of the content stored in the web-based mobile phone terminal server 15 is suppressed.

According to a twelfth aspect of the present invention, in the mobile intranet system according to the twelfth aspect, the Web mobile phone terminal server 15 converts the HTML into a Web mobile phone terminal that allows a registered member to view the Web member. A document and an HTML document converted for a web-based mobile phone terminal that allows browsing when a user other than the member accesses the web-based mobile phone terminal, and a valid authentication code is issued from the web-based mobile phone terminal 31. If no input is made, a configuration is adopted in which access to HTML documents converted for Web mobile phone terminals that are permitted to be viewed by users other than members is authorized.

[0024] With this configuration, the mobile intranet system can provide information to the Web mobile phone terminal holder by installing the mobile intranet system in a network accessible from the Internet. By combining with an authentication system, limited information can be provided to members, and versatility is enhanced. In addition, the user authentication makes it possible to browse contents on the WWW and related information on a Web mobile phone terminal by distinguishing between a specific member and an unspecified number of non-member users.

The expiration date of the HTTP cookie is limited to the currently connected session, and the identification code ID
And the DES encrypted personal identification number as a value. Then
The site top page for the user is displayed on the WWW browser that is the client terminal that the user is browsing (S534). Then, the identification code ID specified in the URL and the DES encrypted personal identification number are used as the HTTP coo.
It is determined whether the contents are the same as the contents of kie (S536). If they are equal, the user authentication is performed, and the user freely browses the page in the site (S538). Then, page browsing is continued until there is a browsing end request (S540). When there is a browsing end request, the HTTP cookie is deleted (S542), and the process is terminated.

FIG. 8 is a flowchart showing an example of a site browsing procedure in a Web mobile phone terminal. The Web-based mobile phone terminal displays in the memory of the terminal that the site top page for the user can be registered (S550). W
When Netscape is used for the WW browser, this page registration is also called a bookmark. In response, the user bookmarks the site top page for the user (S552). When the user accesses the bookmark in which the site top page has been registered in the case of access from the Web mobile phone terminal, the authentication procedure is not required (S554). Next, when the authentication is completed, the web-based mobile phone terminal server 15 checks whether the access is from the web-based mobile phone terminal (S556). When the access from the Web mobile phone terminal is confirmed, the user freely browses the page in the site (S558). Then, page browsing is continued until there is a browsing end request (S560), and when there is a browsing end request, the process ends.

When accessing the mobile intranet system from the Web mobile phone terminal, various inputs such as input of URL are required. The simple access function can simplify the trouble of the user and omit the setting of the ID and the password. FIG. 9 is a flowchart illustrating the simple access function. The user accesses the public top page of the mobile site using the WWW browser, and transitions from the public top page to the member authentication page (S570). On the member authentication page, the user inputs the identification code ID of the existing authentication system and the set personal identification number for the mobile phone terminal for Web (S572).

When the user selects the URL in the body of the e-mail, a member authentication page in which the identification code ID has been input is displayed on the Web mobile phone terminal (S598). Next, the user inputs a preset personal identification number (S599). Subsequent processing is performed by transiting to S524 of FIG.

In the device configured as described above, W
Two types of menus are available for connection from the eb mobile phone terminal to the mobile intranet system: a system that can be viewed by all Web mobile phone terminal contract users and a system that can be viewed by a specific user specified by the system administrator. are doing. In order to utilize it in a closed environment such as a membership organization, security is improved by using authentication technology.

[0038] Of the membership organizations, various corporations such as corporations and local public bodies often have a LAN system or the like for information sharing. When accessing the mobile intranet system from the Web mobile phone terminal, by utilizing the existing installed authentication server, it is possible to improve security and improve user convenience. At the same time, when browsing information using a WWW browser, the session can be managed using an HTTP cookie, so that access from an unauthorized WWW browser can be avoided. This technology has greatly contributed to improving security. Further, by making it independent from the existing authentication server, the authentication of the mobile intranet system can be made independent from the information of the authentication server. As a result, security can be duplicated,
Even if an unauthorized access is made to the mobile intranet system, information contained in the existing authentication server can be prevented from leaking.

FIG. 11 shows an HTML document for WWW on the Web.
Is a flowchart for explaining a function of converting an HTML tag for a mobile phone terminal. Web-based mobile phone terminals use the compact HTML WW on the Internet.
A language that simplifies HTML used as a standard for W is used as a description term of a document. Compact HT
Since MLs are limited in the tags (display instruction commands) that can be used, WWW contents cannot be directly used for Web-based mobile phone terminals. At the same time, the tag contains important information for constructing the page layout, and if rewritten, the layout is broken, and there is a risk that the user will provide meaningless information when the user browses. Therefore, it is necessary to perform optimization while keeping tags as much as possible.

Further, a certain type of device such as a mobile phone terminal for Web has an image format of 2 bit GIF at the time of initial shipment.
If only images in the other formats are allowed and an image in any other format is read, unnecessary waiting time will be required, and unnecessary data will flow, causing unnecessary packets to flow and being reflected in the monthly usage fee. There are issues. At the same time, HTML that can be displayed is limited due to system limitations of Web-based mobile phone terminals.
There is a restriction that the kanji code of the document is only shift JIS and the document per page is less than 5 kilobytes.

Taking the above restrictions into account, the mobile intranet system converts a WWW HTML document into an HTML tag for a Web mobile phone terminal as follows. First, the administrator performs conversion setting (S1102). The item to be converted is the starting page UR of the page group to be converted.
L, the number of layers from the starting page, the number of divided lines of the page, the update frequency, and the title. The converted items are registered in the Web mobile phone terminal server 15 from the administrator terminal 12 by data transmission (S1104). Furthermore,
The web-based mobile phone terminal server 15 stores the input data in the mobile phone database server 16 (S110).
6). The title is added to the related WebPage management menu (S1108).

The Web mobile phone terminal server 15 waits until the update frequency reaches the designated time (S111).
0), when it is confirmed that the designated time has been reached (S111)
2) Acquire the starting HTML document and set the hierarchy to zero (S1114). Next, the acquired H
It is checked whether a link instruction tag to the same WWW server as the TML document is included (S1116), and if the tag is not included, the process ends. If it is included, the link destination URL is held in the memory, and the hierarchy is incremented by +1 (S111).
8). Next, it is checked whether or not another link destination is specified in the same document (S1120). If another link destination is specified, S11 is performed.
Return to 18. If there is no other link destination designation, it is checked whether the hierarchy is less than the setting of the administrator (S1122). If the hierarchy is less than the setting, the process returns to S1118 to acquire a document of a deeper hierarchy. When the hierarchy reaches the setting, the link destination HTML document stored in the memory is obtained, the link information is rewritten, and the link information is stored in the mobile phone database server 16.

Here, in order to realize the functions of S1110 to S1122, in the mobile intranet system, W
A method of periodically acquiring an HTML document on the WW by a robot is adopted. The advantages are as follows. Once the HTML document has been obtained, it is easy to freely process it. Even if the server of the acquisition source goes down, the data is acquired from the local disk of the mobile intranet system, so it is not affected. By combining with a full-text search engine, keyword search becomes possible. This greatly improves searches from vast resources. When managing the pages to be moved, the terminal display agent does not need to query the database each time, which simplifies the mechanism and improves the speed.

The robot starts acquiring an HTML document starting from a URL registered every cycle designated by the administrator, for example, every 3 hours, 6 hours, 1 day, 3 days, 1 week, and 1 month. The acquired HTML document is stored in a file format on the hard disk of the mobile intranet system. For example, “http: //www.△△△.com/cfo/dfo/
If you get the URL "index.html", "/ r / http:
//www.△△△.com/cfo/dfo/index.html ”. At this time, all the hyperlinks should be called from the display agent for Web mobile phone terminals. Rewritten.

Some normal URLs do not indicate a link in a file specification format. For example, "http: // w
ww. △△△ .com / ”etc. In the above case, when saving locally, use“ http: //www.△△△.com.com/index.ht ”.
ml ”and the file name are auto-completed and saved.
In a WWW server implemented by IX, a symbol “〜” (tilde) indicating a personal home directory may be included. Since "~" is a special character, it is all deleted. The Web-based mobile phone terminal display agent holds the conversion information, accesses the file, and displays the information.

Further, the mobile intranet system is designed so that a robot accesses an existing WWW server and acquires a document. At that time, the robot automatically patrols based on the URL set by the administrator. The administrator can set how many layers can be moved from the starting URL. As a result, it is possible to restrict the pages that can be browsed from the Web mobile phone terminal. If the specified layer is separated from the starting layer by more than the specified layer, the link acquisition is abandoned. At the same time, in the mobile intranet system, the WWW server to be obtained is obtained only by the WWW server designated by the administrator. As a result, even if a link to another WWW server is included in the HTML document, the acquisition is stopped at that point, and the processing shifts to the analysis of the part including the hyperlink to another same host. As a result, unexpected disclosure of the content can be prevented.

Further, the administrator can make detailed settings for the robot. For example, by not permitting movement to another WWW server, conversion of an HTML document (for example, a newspaper company) posted on an unacceptable WWW server can be prevented. With this, unexpected HTML
Document conversion can be prevented, and copyright infringement on the HTML document creator can be prevented.

Further, by the patrol by the robot, the hyperlink in the HTML document stored in the hard disk in the system is rewritten so as to call the Web mobile phone terminal display agent. In FIG. 11, a link between different WWW servers cannot be moved, but is described.
It may be configured to have a function of freely moving between WWW sites permitted by the administrator. Thus, depending on the setting of the administrator, the movement between the WWW servers is realized, and the convenience is not impaired at all.

FIG. 12 is a list of corresponding tags for converting an HTML document into an HTML tag for a Web-based mobile phone terminal.
The document format conversion means 155 performs the following optimization and performs HTM
Process and display the L document. All normal hyperlinks and hyperlinks using style sheets are changed so that they are referred to as arguments from the display agent program. If line break instructions (tags such as <BR> and <p>) are continuous on two or more lines, it is often meaningless for content browsing.
All duplicate instructions are once deleted and optimized to one. The table display (<table> tag) cannot be recognized by the Web mobile phone terminal. If this tag is included in the HTML document, the <table> tag is deleted. In a hurry, change the display to itemize each <td> and <th> tag that distinguishes each column. If a <tr> or </ tr> tag indicating the end of a line is included,
Change the lines so that they are clearly distinguishable.

Web mobile phone terminals do not support an automatic transition instruction of an HTML document using a meta tag. Automatic transition instruction of page by this meta tag is HTML
If included in the document, remove the meta tag,

The message "META tag specification" is displayed and the link can be changed. Web-based mobile phone terminals do not support a frame <frame> tag for displaying a page in a divided manner. Recently, there are many WWW sites that use frames, and these can be displayed on a Web-based mobile phone terminal. Specifically, when a tag called <frameset> tag for initializing a frame is included, a message “a frame is used in this page” is displayed on the web-based mobile phone terminal. The <frame> tag usually contains the name of the HTML document file that constitutes the frame and the layout information of the frame. However, in the mobile intranet system, the purpose is to enable page transition, so that the frame Extract the HTML document file name, assign a serial number, and follow the link
Reconstruct the ML document. Also delete all <noframe> tags that are displayed for browsers that do not support frames.

Sending information from the page to the server <fo
Basically, delete all rm> tags. Basically, delete all <img> tags that display image information. Delete all JavaScript tags and Applet tags that cannot be interpreted by the web-based mobile phone terminal. Delete all <font> tags that specify the font size. (10) When describing an HTML document, the kanji code is EUC
Code, JIS code, shift JIS can be selected. A normal WWW browser can automatically determine a kanji code. However, the browser mounted on the web-based mobile phone terminal only allows shift JIS for kanji codes. In addition, in a normal HTML document, meta
In general, a kanji code is defined by an instruction tag called a tag. From these, the kanji code of all HTML documents is changed to shift JIS. At the same time, when viewing an HTML document from a WWW browser, all meta tags are changed to support the shift JIS in order to avoid occurrence of display abnormality of the content.

(11) The comment tag (<!-~->) Tag is deleted. (12) When the above document format conversion of the entire page is completed,
Check the converted page again. Generally, in an HTML document, structural information is controlled by a tag, so that all line feeds included in the HTML document are ignored during display. However, in the mobile intranet system, in order to divide a page by the number of lines, all unnecessary line breaks are deleted and unified into structural information indicated by a tag. As a result, it is possible for the administrator to efficiently perform page division with the number of lines specified. At the same time, CR and LF of line feed code are all L
F. (13) Delete all unnecessary byte characters such as duplicate spaces.

As described above, in the mobile intranet system, it is possible for the system administrator to control the system using the WWW interface without any knowledge of editing the HTML document. All control of the system can be realized by using a WWW browser. It has the following functions. The titles of the pages obtained by the robot can be freely rearranged and displayed. Thereby, for example, in the case of the job hunting season, the WW that provides job-related information
It is possible to move the information of the W server upward, or delete it when the time has passed. This is realized by setting a weight for each registered page for the administrator. The weight can be set in 10 levels, and a mechanism in which the one with the larger weight comes up is adopted. You can also delete the index by simply checking the checkbox.

The WWW interface is linked to a robot that acquires HTML documents from a WWW server, and an administrator can easily publish pages by adding an index. In addition to the pages acquired by the robot, statically prepared pages can also be controlled by the WWW interface. Here, the authentication information can be inherited, and only a limited number of users can view the information.

FIGS. 13A and 13B are explanatory diagrams of a document arrangement by document conversion. FIG. 13A is an HTML document for WWW, and FIG.
HTML document converted for a mobile phone terminal. Although the mobile intranet system has a function of optimizing and converting and displaying a page, there is a possibility that the page may be converted into a page that is not intended by the creator of the HTML document. At the same time, the patrol period of the robot is, for example, at least one hour, and there is no guarantee that the patrol will start immediately. As a solution to these problems, the creator of the HTML document can check in advance how the page will be converted. As a result, when converting important information, it is expected that the possibility of transmitting incorrect information is greatly reduced. Also, by making this page publicly available, it can be used by an HTML document creator in the organization.

FIG. 14 shows an HTML document for WWW on the Web.
FIG. 7 is an explanatory diagram of a specific example converted into an HTML document for a mobile phone terminal for use in mobile phones. In the figure, an HTML document for WWW includes a top page (A1) of "@Gakuen Job Hunting Department", a page (A2) of "Job Hunting Event Information" located in the next hierarchy, and "HTML" in the second hierarchy. (A3) for use during the spring holidays. Correspondingly, Web
HTML document for mobile phone terminal is "Gakuen Job Hunting Department"
Page (B1), a page for the "Job Employment Event" located on the next level (B2), and a page on the second level for "Use during the Spring Break" (B
3) Further, it has a page (B4) of “display of unlinkable hierarchical document” located at the third hierarchical level.

FIGS. 15 to 17 are flowcharts for explaining the state of browsing the converted HTML document in the Web-based mobile phone terminal. First, a related WebPage menu screen is displayed on the Web-based mobile phone terminal (S150).
2). Then, a page title to be browsed is selected from the list (S1504), and the starting HTML document name is set in the page name and zero is set in the position information (S1506). Mobile phone terminal server 15 for Web
Acquires the HTML document corresponding to the page name from the hard disk in the system (S1508). If it cannot be obtained, a link disapproval display is performed on the Web-based mobile phone terminal.

The acquired HTML document is read all at once into the memory in the Web-based mobile phone terminal server 15 (S
1510). Then, the kanji code is converted to EUC and full-width conversion of half-width katakana is performed (S1512). And HTM
L tag analysis is started (S1514), and tag optimization is performed (S1516). Then, unnecessary blank lines and unnecessary blanks are deleted from the converted document (S1518). Then, it is checked whether the number of lines of the entire document is less than (position information + 1) × (the number of lines specified by the administrator) (S1520). If not, an end code is input to the last line of the specified number of lines (S1522). ), And count the number of lines after that. Then, the number of divided lines and the link button to the first page are added to the memory (S1524).

Subsequently, the kanji code is shifted from EUC to J
It is converted to IS (S1526). At the same time, double-width alphanumeric characters are converted to half-width alphanumeric characters, and full-width katakana is converted to half-width katakana. If the number of divided lines is 2 or more, "previous page",
A “back page” button is added to the memory (S152
8). Then, the converted HTML document is displayed (S153).
0), the user browses the contents (S1532). Then, when the user selects a hyperlink to another document (S1534), the HTML to be the link destination is added to the page name.
At the same time as setting the document, zero is set in the position information (S1536), and the process proceeds to S1508. When the user selects the “previous page” or “back page” button (S1538), the current HTML document name is set as the page name (S1540). When "previous page" is selected, the position information is set to "-1", and when "back page" is selected, the position information is set to "+1", and the process transits to S1508. When the user selects the "stop" button (S154
2) The current HTML document name is set as the page name and zero is set as the position information (S1544), and S1 is set.
Transition is made to 508. If the user selects the "return" button (S1546), the flow shifts to S1502; otherwise, the flow returns to S1532.

FIG. 18 is a site map showing an example of a mobile site, which shows a case of a school corporation. The mobile intranet system uses the Internet (W
The Web mobile phone terminal gateway server accesses the Internet via the Internet), or is installed in a space accessible from the network where the Web mobile phone terminal gateway server is installed.
Information can be browsed from the mobile phone terminal.

In a system that can be browsed from all Web mobile phone terminal contract users, the WWW for general release such as entrance guidance to universities, disclosure of research contents, open seminars, information on undergraduate departments, etc.
It prepares the contents prepared in the above, and enables the provision of information for those who wish to enroll, parents of those who wish to enroll, high school teachers, preparatory schools for entrance examinations, other university students, faculty and staff. Specific contents include information on university entrance, the spirit of foundation, the history of establishment, organizational information on the university, information on entrance examinations, laboratory research, faculty and staff information, and public seminar information.

In a system that can be browsed by a specific user designated by the system administrator, students who live on campus,
The University Secretariat will provide information to faculty and staff, information on course cancellations, course information, on-campus schedules, calendars, etc., to improve user convenience. Specific items include the following items.

Emergency News Information that occurs irregularly, such as notification of facility construction and special seminars, can be transmitted to students independently or by a plurality of university offices. In addition, if a natural disaster occurs, for example, if the university is closed due to heavy snow, etc., there is a mechanism to broadcast simultaneously to students, faculty and staff,
It can be used as an emergency means of contacting faculty and staff.
Only the administrator having the administrator ID can input the emergency news, and also input the ID and password of the existing authentication system, thereby maintaining double security. At the same time, it is possible to prevent improper information from being input by separately storing in the database who has input the emergency news to the mobile site.

University calendar Information regularly generated for students, opening hours of various counters,
Provides schedule information for each department. The input of the university calendar data is in CSV (Comma Separated Value) format, and can be input to the server side by the administrator side in a lump. Here, CSV is
A data format in which each field in a record is separated by commas and records are separated by line feed codes. The data can be posted by the administrator for each department or all departments at once. When accessing from the top page in the menu on the Web mobile phone terminal side, a list of window opening hours of the day is displayed. If there is a schedule, a hyperlink is displayed, and when the user selects it, the content is displayed. If there is no plan, W
The contents of the department for which the WW conversion function is set are automatically displayed. If the conversion function is not set, no hyperlink is displayed, and there is no need to follow useless links.

Related WEB page Connects to the campus intranet WWW and other WWW sites designated by the system administrator and
The information of the WW page can be automatically converted for the Web mobile phone terminal and displayed on the screen of the Web mobile phone terminal. Specifically, refer to facilities on campus, find employment-related pages,
Event schedule, computer center, contact from library, new information, window opening time, etc. In addition, there are websites related to mobile phone terminals for web that are useful for student life, and a list of phonebooks that can be more convenient to share by sharing the campus life. As for the telephone directory, it is preferable that the function of the Web-use mobile phone terminal allows a user to directly make a telephone call by selecting a hyperlink.

It should be noted that the above-mentioned information of the WWW page is
When converting all HTML documents as a target, the function of automatically converting the original HTML document and displaying it on the Web mobile phone terminal may infringe the copyright held by the creator of the original HTML document. As a countermeasure against this copyright infringement problem, a system administrator can freely set a hierarchy that can be browsed by a user from a Web mobile phone terminal. Even if the HTML document is a hyperlinked HTML document, the HT included in the server specified by the administrator
It has a function to prevent browsing other than ML documents.

Cancellation Information Since information on lectures can be obtained, the cancellation information can be quickly obtained. Information on canceled classes is obtained automatically and periodically from the on-campus host computer and provided. My curriculum It is possible to collectively manage timetables (learning information), personal schedules of students, faculty and staff (private schedule). For the course information, the timetable of the corresponding student is selected and displayed in conjunction with the authentication information. This allows the student to check the timetable of the daily schedule on the Web mobile phone terminal. At the same time, students' individual schedules can be managed. The schedule can be entered by using either a WWW browser or a web-based mobile phone terminal. When browsing from a WWW browser, it has a function to efficiently enter a schedule.

In addition, since the WWW browser has a function of batch inputting the schedule in the CSV format to the Web-based mobile phone terminal server 15, it is possible to cooperate with software such as another scheduler. This allows students to manage their lecture schedule and private schedule daily. That is, the mobile phone terminal for Web has a function like an electronic organizer. This allows students to spend more efficient campus life.

The address book registered in the My Address Book or the System Book can be managed and browsed on the Web mobile phone terminal. As with the private schedule described above, the address book can be entered from either a WWW browser or a web-based mobile phone terminal. Also WW
Since the W browser has a function of batch inputting the address book in CSV format, it is possible to cooperate with other address management software. In addition, it has a function to use a common address book for each group, so that information can be shared in, for example, a laboratory or a seminar.

Confirmation of Courses In connection with the above-mentioned my curriculum, students' course information can be checked from the on-campus database. The student submits the course registration report to the Academic Affairs Department, and the user can confirm whether there is any error in the content on the Web mobile phone terminal. For example, contents such as registered lecture time being duplicated or registered lecture not being opened are displayed. Students can refer to the content and correct the registration again.

Club Activity (Club, Circle) Information A bulletin board function makes it possible to browse the activity schedule of club activities and club activities on campus. It is possible to contribute to the enhancement of communication between members. Laboratory Information The bulletin board function makes it possible to view the activity schedule of the laboratories on campus. It is possible to contribute to the enhancement of communication between laboratory members. (10) University organization information We can provide information on the organization within the university. Specifically, there is information from the president, each faculty, the employment department, the educational affairs department, and the like. (11) Co-op information Information on co-ops that provide inexpensive products to student faculty and staff will be provided. Specifically, sales of magazines and textbooks, inventory information,
Information on travel, CDs, etc., driving school, language school information, etc.

In the above embodiment, a case has been described where a mobile intranet system is constructed by taking a school corporation as an example. However, a university co-op, a local co-op, a department store / department store,
Applicable to local supermarkets, shopping streets, educational institutions, and various membership organizations. The mobile intranet system can be used anywhere if it is installed on a network accessible from the Internet. At the same time, if a mobile intranet system is connected to an authentication system that has a mobile intranet system in advance, it is possible to additionally install the mobile intranet system in a data center that provides specific information to members. As a result, services for members can be developed.

University Co-op The University Consumer Co-op is characterized in that it enables PR (Electric Commerce) of various products and services handled by the co-op targeting university students, using a mobile phone terminal for the Web. There is. Furthermore, simultaneous distribution of information becomes possible by using a mail transmission function which is a basic function of the Web mobile phone terminal system. If a similar mobile intranet system has already been introduced at a university, or if it is to be introduced at the same time, a synergistic effect can be achieved by sharing contents and sharing menus.

Regional Co-op A local co-op provides local store sales and delivery services. In the case of store sales, we will provide various consumer information such as promotion of special sale items, promotion of visits to the store, provision of local information, provision of health information, provision of living information, etc. Can be promoted. In the case of the delivery service, information is usually communicated on a paper basis, but it is possible to receive and place orders using Web-based mobile phone terminals, promote products, provide health information, and provide food knowledge. In this way, it is possible to provide daily life information, etc., and to provide more necessary information to consumers. It also leads directly to efficiency.

Department stores and department stores Department stores and department stores are currently developing various measures, such as issuance of point cards, in order to enclose customers. However, by transmitting information using a mobile phone terminal system for the Web, There are two advantages. (i). Follow-up to your specialty becomes possible in a timely manner. Event information, bargain item information, point information, and trend information are provided by a Web-based mobile phone terminal system, so that for customers who have high purchase prices, it is possible to enclose information such as high-priority information and high-priority information. A synergistic effect can be expected by linking with existing point cards and DMs issued at department stores and the like. (ii). Information can be transmitted to general customers. W
The characteristics of the web mobile phone service of the web mobile phone terminal system are its portability such as being able to catch information anytime and anywhere, instantaneousness, and personality. There is a merit that can be transmitted. In particular, department stores that mainly target young people can improve the visit rate by providing information on trends, bargain items, and topical products. Moreover, by continuously transmitting information, it becomes possible to enclose the user with specialty. Further, a synergistic effect can be expected by linking with the Web site.

Regional supermarkets Information on special sales of local retailers, which has been provided by insert leaflets and the like, can be transmitted by a Web mobile phone terminal. In addition, a retailer who already owns a homepage can construct a more effective information provision mechanism by linking it with an existing webpage. In addition, by transmitting information regularly, it is possible to keep customers in place and differentiate from other major supermarkets and convenience stores.

Shopping streets One of the reasons for the decline of shopping streets in recent years may be a decrease in the rate of attracting customers due to competition with major supermarkets and convenience stores. However, since the mobile intranet system can provide customers with more community-based information. It is possible to stop customer loss. Specifically, even when it is difficult to construct a system only by a retail store, information can be provided as a local shopping district, and an efficient system can be constructed mainly by providing information on nearest products. If you already own a shopping street homepage,
Content can be automatically converted from the site, and similar information can be provided to customers near the shopping district. In addition, since it is possible to send information to housewives who work and work at the company during the daytime, which is a customer group who works at the company, the housewife can return shopping information while staying at the company, and stores such as when to close. You can get city information. In building the system, it is not necessary for each store or the like to purchase a server by the hosting service provided by the data center, and the system can be constructed without waste.

Educational Institutions In addition to universities, application to kindergartens, nursery schools, elementary schools, junior high schools, high schools, junior colleges, study private supplementary schools, cooking schools, cooking schools, English conversation schools, computer schools, culture centers, business schools, sports clubs, etc. The feature is that it can be easily performed. In kindergartens and nursery schools, parents of kindergartens can be notified in a timely manner about childcare information, various information on kindergartens and nursery schools, and unexpected matters.
Parents can easily obtain information, so they can perform their jobs with peace of mind. In addition, since event information can be quickly obtained from a destination, scheduling can be made with private in mind. Similarly, at elementary schools, junior high schools, and high schools, information can be transmitted to parents as parents.

In addition, with regard to private schools such as the study private supplementary school and the preparatory school, examination information from the school side, schedule and curriculum information can be provided to the private school students and the preparatory school students. Living information can be provided to parents who have children.
Furthermore, it is also advantageous that information can be easily transmitted to students at a culture center and an English conversation school.

Various Member Organizations Information can be easily shared even with small groups such as fan clubs and local baseball teams. In the portability, which is a major feature of the mobile intranet system, the conventional information communication uses a LAN system to share information in a fixed place such as an office,
If the user is out of the office, a mobile phone is connected to the notebook computer and the office LAN system is accessed by remote access. However, the web mobile phone terminal system can take on the role of an intranet in the company. Was. If the company has already sent information on the website, it will automatically convert the content,
The content can be converted to the content for the Web mobile phone terminal system without any trouble.

In the above embodiment, the case where the Web mobile phone terminal uses the Compact HTML has been described. However, the present invention is not limited to this, and the WML (Wir
The present invention can be similarly applied to a Web mobile phone terminal using another language such as eless Markup Language (eless Markup Language), for example, a Web service provided by DDI under the trade name EZWeb.

[0082]

As described above, according to the mobile intranet system of the present invention, the WWW server from which the HTML document is to be obtained, and the HTML in which the upper limit of the number of hyperlink layers of the HTML document is set.
W set by the document management means and the HTML document management means
HTM communicated with WWW server and stored in WWW server
HTML document acquisition means for acquiring an L document, hyperlink structure analysis means for analyzing a hyperlink structure in the acquired HTML document, and HTML document to be hyperlinked to the acquired HTML document, the upper limit of the number of hyperlink layers Means for acquiring a hyperlink document within a range of values, HT acquired within a range of an acquired upper limit of the acquired HTML document and the number of hyperlink layers.
A document format conversion unit for converting an ML document into a document format for a Web mobile phone terminal, and a Web mobile phone terminal document storage unit for storing the converted Web mobile phone terminal document. So the intranet,
An HTML document transmitted to the Internet can be easily transmitted to a Web-based mobile phone terminal by a single document format conversion. Therefore, the creator of the HTML document only needs to once designate the URL or the like including the name of the WWW server where the HTML document to be created is stored on the management screen of the mobile intranet system or the management screen of the mobile intranet system. After that, the creator of the HTML document only needs to be aware of the normal update work of the HTML document.
Thereafter, the HTML document acquisition unit, the hyperlink structure analysis unit, the hyperlink document acquisition unit, the document format conversion unit, and the document storage unit for the mobile phone terminal for the Web process appropriately.

Further, as in the embodiment, when the server for the mobile phone terminal for Web also serves as a gateway server for transmitting information to the mobile phone terminal for Web,
There is no need to install a plurality of servers, and only one server has the role of a Web mobile phone terminal gateway server for the entire organization. For this reason, the introduction cost can be significantly reduced.

According to the present invention, in a mobile intranet system for acquiring Web information stored in a Web-based mobile phone terminal server using a Web-based mobile phone terminal, a user of the Web-based mobile phone terminal server is provided. And a member authentication unit for authenticating a user registered in the member management unit by using an identification code, and using an operation key of the web-based mobile phone terminal to execute an authentication code. Is entered, and when the entered authentication code matches the authentication code registered in the member authentication means, access from the Web mobile phone terminal to the Web mobile phone server is authorized. The authentication server installed in the organization can be used for the system, and the identification code ID can be unified. This greatly improves user convenience.

Also, identification code IDs and passwords registered in an authentication server usually installed in an organization usually contain complicated alphanumeric characters, and it is convenient to input them from a Web mobile phone terminal. Expected to be significantly impaired. Thus, as shown in the embodiment, if authentication using a password is introduced, if only an ID is input, an HTML document in the intranet can be accessed only by inputting a simple registered password. Further, if the "simple access function" by the WWW browser shown in the embodiment is used to support the ID input, even the complicated ID input on the Web mobile phone terminal is unnecessary, and the convenience of the user is remarkably improved. .

Further, according to the present invention, since information can be transmitted to a Web-based mobile phone terminal regardless of the information content,
Necessary information can be accessed not only by the in-house LAN environment but also by the users located in the service area where the Web mobile phone terminal can be used to access the same latest information.
