Description

  The present invention relates to the World Wide Web (WWW), which is an information disclosure mechanism used through a network all over the world spread like a spider web. The present invention relates to a web information providing method and apparatus for transmitting information corresponding to a transmission area to a user by using information on an area where the user has transmitted the transmission request (hereinafter, referred to as a user transmission area) when a request is transmitted.

  A user who wants to browse a WWW web page can browse a desired web page using a computer terminal and software called a browser. However, in many cases, the use of the Internet is indispensable for browsing a web page, and a general user uses a 32-bit integer, for example, an IP (Internet Protocol) such as "202.224.36.35". You are connected to the Internet via a provider that temporarily assigns addresses to your computer terminals. Further, the user makes a transmission request of the web page data stored in the web server on the Internet to the web server, and the web server transmits the web page data in response to the transmission request, whereby the user Can view web pages on a browser.

  FIG. 9 is a diagram illustrating a conventional web information providing apparatus. The conventional web information providing apparatus 100 includes user terminals 101a to 101c, first modems / TAs (Terminal Adapters) 103a to 103c, analog / digital lines 105a to 105c, and second modems / TAs 107a to 107c. The access points 109a to 109c, the servers 111a to 111c in the access points 109a to 109c, the first gateways 113a to 113c, the Internet 115, the second gateways 117a and 117b, and the web servers 119a to 119b. It is configured with.

  Hereinafter, the operation of the conventional web information providing apparatus 100 will be described. A general user who intends to use the web information providing apparatus 100, for example, a user in Tokyo, dials the access point 109a in Tokyo of the provider from the user terminal 101a using a communication program called communication software. When the user terminal 101a is connected to the access point 109a through the first modem / TA 103a, the analog / digital line 105a and the second modem / TA 107a, the access point 109a sends a user terminal transmission request such as a login name and a password. In response to the request, the user terminal 101a transmits information such as a login name and a password to the access point 109a.

  If the login name and password transmitted from the user terminal 101a to the access point 109a are correct and the communication environment settings of the user terminal 101a are usable at the access point 109a, the user terminal 101a is a server of the access point 109a. Connected to the terminal 111a, the server 111a of the access point 109a selects one IP address from a plurality of IP addresses possessed and allocates the selected IP address to the user terminal 101a. This assignment means that the user terminal 101a has acquired one IP address.

  Next, when the user uses the WWW, the user analyzes web data such as a program described in HTML (Hyper Text Markup Language), which is a language for describing a file in a hypertext format, and analyzes the text or text. A browser that displays and reproduces still images, moving images, and the like on the user terminal must be set in advance so that it can be used on the user terminal. The browser is software having a function of easily jumping to a site having related information or a target file on the Internet by performing a click operation using a pointing device on a screen of a user terminal.

  After the IP address is assigned from the server 111a to the user terminal 101a, the user inputs or selects a URL (Uniform Resource Locator) that expresses the type and storage location of the data at a time using a browser. This URL may be a character input to the input part of the browser using a keyboard, or a part linked to a desired URL on a web page may be selected using a mouse pointer.

It is assumed that the URL of the web page that the user wants to browse is “HYPERLINK http://www.xxx.co.jp/index.html http://www.xxx.co.jp/index0.html”. In this URL, the head "http: //" indicates HTTP (Hyper-Text Transfer Protocol) which is a protocol for web data communication, and then the web server name "www" and the domain name "xxx.co.jp" Followed by the file name "index0.html". When the user inputs or selects this URL in the browser, the user terminal 101a stores “index0.html” which is a type of web data stored in the web server 119a “www” of the domain “xxx.co.jp”. To the access point 109a, the transmission request of the HTML data of the text file, the IP address of the user, and the browser information for determining the type of browser used by the user.

  Next, the server 111a that has received these information transmits the transmission request, the IP address, and the browser information to the Internet 115 to the “www” web server 119a of the “xxx.co.jp” site. When the web server 119a receives these pieces of information, the web server 119a transmits the designated file, in this example, "index0.html" to the user terminal 101a via the Internet 115 and the access point 109a. Further, the web server 119a analyzes the program of the “index0.html” file, and transmits other data referred to to the user terminal 101a.

  The web data obtained by the user terminal 101a in this manner, that is, the data of the “index0.html” file and the data referred to by the “index0.html” are analyzed by the browser of the user terminal 101a, and characters, still images, moving images, etc. Displayed with. Further, according to this system, the same information is displayed on the user terminal regardless of where the web page is viewed from. Therefore, the above-described conventional web information providing apparatus reduces a regional disparity in using information.

  However, local information such as advertisements and weather forecasts that have nothing to do with the transmission area of the user has a problem that the advertising effect is small for people outside the transmission area and the utility value is low.

  In addition, when the user wants to display information related to the area among a large number of web information, the user manually inputs the URL from the keyboard into the input part of the browser, or links to the URL with the mouse pointer. It has been essential for the user to once perform a selection operation relating to the area, as if selecting a part. Therefore, this operation is not only troublesome, but also difficult and inconvenient for those who are not good at operating the user terminal and the browser.

Hereinafter, the prior invention relating to the present invention will be described with reference to FIGS.
[First Prior Invention]
FIG. 1 is a diagram showing a web information providing device (system) according to a first prior invention. (However, the same members as those in the prior art are denoted by the same reference numerals.) FIGS. 2 and 3 are flowcharts showing the web information providing method according to the first prior invention. Hereinafter, a web information providing apparatus of the present invention and a web information providing method using the same will be described in detail with reference to FIGS. The web information providing apparatus 200 of the present invention includes user terminals 101a to 101c, first modems / TAs 103a to 103c, analog / digital lines 105a to 105c as communication networks, and second modems / TAs 107a to 107c. , Access points 109a to 109c, servers 111a to 111c in the access points 109a to 109c, first gateways 113a to 113c, the Internet 115 as a communication network, second gateways 117a and 117b, and automatic selection means. The web information providing apparatus 200 is provided with an IP address pool database 201 as an IP address vs. regional database.

  Hereinafter, the operation of the web information providing apparatus 200 of the present invention will be described. A general user who intends to use the web information providing apparatus 200, for example, a user in Tokyo, dials the access point 109a of the provider from the user terminal 101a using a communication program called communication software (step 401). When the user terminal 101a is connected to the access point 109a through the first modem / TA 103a, the analog / digital line 105a and the second modem / TA 107a (step 403), the access point 109a transmits the user's login name, password, and the like. A request is made to the user terminal 101a (step 405), and the user terminal 101a transmits information such as a login name and a password to the access point 109a in response to the request (step 407).

  If the login name and the password transmitted from the user terminal 101a to the access point 109a are correct and the communication environment setting of the user terminal 101a is usable at the access point 109a (step 409), the user terminal 101a sets the access point. Connected to the server 111a of the access point 109a (step 411), the server 111a of the access point 109a selects one IP address from a plurality of IP addresses possessed and assigns it to the user terminal 101a (step 413). This assignment means that the user terminal 101a has acquired one IP address as regional information.

  Next, when the user uses the WWW, the user analyzes a web data as web information such as HTML data and displays and reproduces a text, a still image, a moving image, and the like on the user terminal in advance on the user terminal. It must be set so that it can be used in 101a.

  After the IP address is assigned from the server 111a to the user terminal 101a, the user inputs or selects a URL, for example, as shown in FIG. This URL may be input by characters into the input part of the browser using a keyboard, or a part linked to a desired URL on a web page may be selected by using a mouse.

  It is assumed that the URL of the web page that the user wants to browse is “HYPERLINK http://www.xxx.co.jp/index.html http://www.xxx.co.jp/index1.html”. When the user inputs or selects this URL in the browser, the user terminal 101a stores “index1.html” which is a type of web data stored in the web server 119a “www” of the domain “xxx.co.jp”. A transmission request of the HTML data of the file, a user's IP address, and browser information for determining the type of browser used by the user are transmitted to the server 111a of the access point 109a (step 415).

  Next, the server 111a that has received the information transmits the transmission request, the IP address, and the browser information to the Internet 115 to the “www” web server 119a of the “xxx.co.jp” site ( Step 417).

  When the web server 119a receives the information (step 419), the web server 119a analyzes the program of the "index1.html" file requested to be transmitted (step 421), and retrieves the web data and the reference in "index.html". The other data being transmitted is transmitted to the user terminal 101a (step 423).

  At this time, in the present invention, it is assumed that, in the program of the "index1.html" file requested by the user to be transmitted, there is a description as a regional program for automatically selecting different data depending on the region. The web server 119a analyzes the program of the "index1.html" file (step 421) and finds a description for automatically selecting different data depending on the area, and finds an IP in the same site or an external site. The originating area of the user is determined using the IP address pool database 201 as shown in FIG. 5, which is an example of a database in which addresses and areas correspond one-to-one, and the IP address transmitted by the user terminal 101a (step 425). .

  After the web server 119a determines the transmission area of the user, the web server 119a selects web data corresponding to the transmission area determined by the IP address pool database 201 (step 427), and in addition to the step 423, the user terminal 101a (Step 429).

  The data of the “index1.html” file obtained by the user terminal 101a, other data referred to by the “index1.html”, and web data such as data corresponding to the region are analyzed by the browser of the user terminal 101a. , Characters, still images, moving images, etc. (step 431).

  For example, assume that “http://www.xxx.co.jp/” is a site that provides weather forecast information. The main page of this site, "index1.html", describes a program for selecting the weather forecast information for each prefecture. The web server uses the IP address pool database to determine the user's transmission area. The weather forecast web data corresponding to the prefecture to which the transmission area belongs is transmitted to the user terminal. Therefore, when the user opens this site, the user can automatically browse the weather forecast of the prefectures belonging to the transmission area of the user on the browser.

  As described above, according to the present invention, it is possible to automatically browse regional information without manually selecting the regional information while browsing a web page, thereby saving the trouble of selection. it can. Of course, if you want to view information in an area other than the user's origin area, the user can connect to an access point in an area other than the origin area or select using the same method as before using the same method as before. It goes without saying that it is good.

  In the present invention, access as a telephone number vs. area database having a database in which the telephone number of an access point and a region correspond one to one instead of an IP address pool database and a telephone number of an access point instead of an IP address pool database. A point pool may be used. The access point may be at either the same site or an external site.

[Second prior invention]
Next, a second prior invention relating to the present invention will be described. FIG. 6 is a diagram showing a web information providing apparatus according to the present invention. The web information providing apparatus 300 according to the present invention is provided with a telephone / postal code database 301 as a telephone number and / or postal code pair area database instead of the IP address pool database 201 of the first prior art. You. (However, the same members as those of the prior art and the first prior invention are denoted by the same reference numerals.)

  Hereinafter, the operation of the web information providing apparatus 300 of the present invention will be described. As in the first prior invention, it is assumed that a program for automatically selecting different data for each region is included in the program of the “index2.html” file stored in the web server 119a. As described in the first prior invention, the web server 119b uses the IP address transmitted from the server 111b and the IP address pool database 201 to determine the originating area of the user. Requesting a more detailed area than the user's originating area, the web server 119b can further restrict the user terminal 101b to the user terminal 101b, such as the user's telephone number (or a part thereof) or the area's postal code. We demand disclosure of such information.

  For example, it is determined that the transmission area of the user determined using the IP address pool database 201 is, for example, “Omiya City, Saitama Prefecture”, but “index2.html” is a more detailed area than “Omiya City, Saitama Prefecture”. If the information is divided into files, the web server 119b requests the user terminal 101b to transmit information such as the user's telephone number or postal code to the web server 119b. When the information is transmitted to the web server 119b, the web server 119b establishes a telephone / postal code database comprising a database in which a telephone number, a postal code, or an address and an area are in a one-to-one correspondence within the same site or an external site. Is used to limit the area, and data corresponding to the area is transmitted to the user terminal 101b via the Internet 115 and the access point 109b.

  Therefore, in the present invention, the user can disclose information such as a telephone number and a postal code, so that the area can be further narrowed down, and the area can be further subdivided than the first prior art. Information can be provided to the user.

  However, in the present invention, when the user terminal 101b transmits a transmission request to the access point 109b, the communication program may be set in advance so as to simultaneously transmit information such as the user's telephone number and postal code. Also, without using a communication program, such information registered in the provider in advance may be automatically transmitted from the access point 109b to the web server 119b. In addition, when the user connects to the connection destination, a function of automatically notifying the connection destination of the user's telephone number is used, and the user permits the provider to transmit the telephone number on the Internet 115 in advance. Thus, the telephone number of the user notified from the user terminal 101b to the access point 109b may be automatically transmitted from the access point 109b to the web server 119b. Further, when the user manually transmits information such as a telephone number and a postal code, information of another area can be obtained by transmitting information of another area.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. 7 and FIG.
[First Embodiment]
FIG. 7 is a diagram illustrating the web information providing apparatus according to the first embodiment. (However, the same members as those of the prior invention are denoted by the same reference numerals.) The web information providing apparatus 400 of the present embodiment includes a group 401 such as a company, a school, and other organizations, a dedicated line 403, and a provider 405. , The Internet 115, a web server 119, and an IP address pool database 201 as an IP address vs. regional database.

  The group 401 has a network for each specific area, and the networks are connected by a dedicated line or the like so that they can communicate with each other. For example, in the present embodiment, the network 401A is provided in Tokyo and the network 401B is provided in Osaka, and are connected to each other. Further, the group 401 is connected to at least one provider by a dedicated line. In the present embodiment, the network 401A is connected to the provider 405.

  At least one IP address is assigned to each network. When a terminal configuring the network uses the Internet, one of the IP addresses owned by the network is used.

  The IP address pool database 201 is a database in which the IP addresses owned by the networks 401A and 401B are associated one-to-one with the regions. In the present embodiment, the network 401A is located in Tokyo, and the network 401B is located in Osaka. Therefore, the IP address pool database 201 associates the IP address owned by the network 401A with Tokyo, and the IP address owned by the network 401B. Osaka is associated with the address. The registration of the IP address in the IP address pool database 201 can be freely registered by the group 401 or the network 401A or 401B.

  Hereinafter, the operation of the web information providing apparatus 400 of the present embodiment will be described. When a user using a user terminal in the network 401A uses the Internet, one of the IP addresses assigned to the network 401A is provided to the user terminal by a server (not shown) in the network 401A. Assigned from. The user terminal is connected to the provider 405 via the dedicated line 403 using the IP address as the ID information of the terminal.

  Next, the user requests transmission of certain web page information by inputting or selecting a URL using a browser. The transmission request is transmitted to the web server 119 having the requested web page information via the dedicated line 403 and the Internet 115, and the IP address assigned to the user terminal is also transmitted at this time.

  The web server 119 analyzes the program of the web page information. If the program includes a description for selecting different information depending on the region, the web server 119 accesses the IP address pool database 201 to access the IP address pool database 201. And the transmitted IP address of the user terminal is used to determine the location area of the user terminal. Next, the web server 119 selects web data information based on the determined location of the user terminal, and transmits the selected information to the user terminal.

  In the present embodiment, a communication network such as a dedicated line and the Internet is used. However, communication using a cable television, a broadcasting satellite (BS), a communication satellite (CS), or the like can be similarly used.

[Second embodiment]
FIG. 8 is a diagram illustrating a web information providing apparatus according to the second embodiment. The web information providing apparatus 500 according to the present embodiment includes a mobile communication terminal 501 such as a mobile phone as a user terminal, a base station 503, a mobile communication network 505 as a mobile communication network, and a base as an IP address versus ID information database. A station ID / IP address database 507, the Internet 115, and a web server 119 are provided.

  There are many base stations 503, and each base station is distributed and arranged for each area, and is connected to the mobile communication network 505 by a dedicated line. In addition, each base station is assigned ID information (hereinafter, referred to as a base station ID) serving as an ID of the base station. Since the base stations are distributed in each area, the base station ID is used as area information.

  The base station ID / IP address database 507 is a database in which the IP address of the mobile communication terminal 501 and the base station ID of the base station to which the mobile communication terminal 501 is connected correspond one-to-one. However, when the mobile communication terminal 501 moves and changes the base station to which the mobile communication terminal 501 is connected, the existing data becomes invalid. Therefore, every time the base station to which the mobile communication terminal 501 is connected changes, a new connection is made. The base station ID of the base station and the IP address of the mobile communication terminal 501 are sent to the base station ID / IP address database 507. Therefore, while the mobile communication terminal 501 is connected to any one of the base stations, the base station ID / IP address database 507 stores data on the correspondence between the IP address of the mobile communication terminal 501 and the base station ID in a dynamic manner. And the latest data is always stored. Since the base stations are distributed in each area, predetermined area information of the base station that owns the base station ID is associated with the base station ID. It should be noted that the base station ID / IP address database 507 can be constructed only by a communication carrier.
