Description

  The present invention relates to a technology for generating an appropriate hyperlink corresponding to a communication carrier of a mobile terminal in data distribution toward the mobile terminal.

Currently, a large amount of electronic information is exchanged through a network such as the Internet.
The information exchanged over the Internet exists in a distributed manner on a plurality of computers so that the address can be specified and accessed by a notation called URL (Uniform Re-Source Locator) so that various types of information can be easily referred to. It is prescribed.

A hyperlink function that easily refers to other data existing on other computers by expressing this URL in data written in a predetermined markup language is often used.
By specifying link destination data information with hyperlinks described in the browsed document information using a Web browser, the viewer can browse a plurality of data across the document, and easily convert it into document information prepared by another computer. Can reach.

  However, since the hyperlink can be freely set without limitation, various hyperlinks can be set depending on the intention of the reference source. Therefore, as you can see from sites that use affiliates, even if many hyperlinks are set, they are not always necessary for viewers.

  In this regard, there is a document information browsing method that can easily select hyperlinks having information required by the viewer and reduce wasted time for browsing, and is included for each hyperlink. It has been proposed to obtain link destination data information, calculate the degree of match based on the relevant information desired by the viewer accumulated in advance, and then characterize the hyperlink according to the calculated degree of match (See Patent Document 1).

On the other hand, in recent years, mobile phones have come to play a role as tools for transmitting / receiving and browsing data via the Internet, beyond the original role of voice calls.
However, in a mobile phone, there are cases where desired data cannot be displayed because communication standards and data formats differ from carrier to carrier.

  In this regard, when distributing video content to a mobile terminal, a technique has been proposed in which the video content is converted into a format optimal for the mobile terminal and distributed. As an example of this, an optimal video conversion for a mobile terminal while referring to the information of the mobile terminal acquired from the user agent transmitted from the mobile terminal that requested the image display by the module that functions according to the parameters such as the type of video content. There is an image processing method that generates an instruction, transmits the instruction to a video server, and converts the image into video content that is optimal for the specifications of the image size, capacity, and the like of the mobile terminal (see Patent Document 2).

JP 2004-341607 A JP 2005-352589 A

  According to the technology described in Patent Document 1, only a hyperlink desired by a viewer can be effectively presented to the viewer, but when the viewer browses a document with a mobile phone, Since it is not determined whether the linked document corresponds to the carrier protocol of the mobile phone, depending on the mobile phone, the linked document is not displayed or the data compression format (regulation) corresponding to the carrier is different. Therefore, if the compression format of the data to be downloaded at the link destination does not support the mobile phone carrier of the viewer, electronic content such as music and video cannot be downloaded, but the hyperlink is There was a problem that it displayed like a link.

Therefore, if the viewer gives a hyperlink without knowing it, the desired content cannot be obtained in the end, and the viewer returns to the original page or responds again in order to download the content. There is a problem in that it is necessary to search and search for carrier data, and the effort and time for that purpose are wasted.
Such a problem is that if the viewer cannot access the link destination despite accessing the advertising link, the viewer's impression of the advertiser becomes worse, and the advertiser's brand image There was a problem of hurting.
In addition, if you use a method that charges in response to a click on a banner ad on a site that uses affiliates, the link destination does not correspond to the carrier of the mobile device used by the viewer, There is a problem that the advertiser is charged according to the number of clicks, even though the viewer cannot actually browse the linked advertisement.
Furthermore, since there is a method of acquiring unauthorized personal information by setting up a site from which content cannot be acquired originally for the unauthorized purpose of acquiring user agent information of the viewer, mobile phone users can feel at ease. There is also a problem that the user does not click on the advertisement because the link cannot be clicked and it cannot be determined whether or not the advertisement is sure even if the advertisement is performed.

Further, according to the technology described in Patent Document 2, based on the user agent acquired from the mobile terminal, it is possible to distribute the optimal video content to the mobile terminal according to the specifications of the mobile terminal.
However, in the document in which the hyperlink is set, there is no disclosure about a technique for determining whether the link destination of the hyperlink corresponds to the carrier of the mobile terminal, and depending on the technique, the link destination document Such an electronic content cannot be prevented from accessing a hyperlink that is not compatible with the portable terminal.

As described above, in the data in which the hyperlink is set, it is not known whether the link destination corresponds to the carrier of the mobile terminal used unless the link destination data is requested. Therefore, the viewer once selects the link destination of the displayed hyperlink, and if there is no data corresponding to the carrier, the viewer receives a message such as receiving a message indicating that the hyperlink is not supported, and the desired information is received. Not only I couldn't see it, but I was annoyed by returning to the original site.
This is because, in mobile phone services, communication and data format standards are not uniform, so in order to distribute data corresponding to all carriers, such data is prepared for the number of existing carriers. Although it must be done, it is caused by the fact that only data corresponding to some carriers is prepared due to cost and the like.

  Therefore, the present invention generates new data whose link destination corresponds to the carrier of the mobile terminal for all hyperlinks in the data transmitted / received by the mobile terminal, and the viewer supports the mobile terminal. The purpose is to prevent access to data that has not been processed.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the system according to the present invention includes a content distribution apparatus 1 including an information processing apparatus 2 and a Web server 3, and a mobile terminal 4, which are configured to be communicable via the Internet. Has been.

  The information processing apparatus 2 is an apparatus that generates new data by converting hyperlink settings based on a predetermined algorithm for data read from the Web server 3 and distributes the data to the mobile terminal 4. The information processing apparatus 2 includes a CPU (Central Processing Unit), a computer program executed by the CPU, a RAM (Random Access Memory) for storing the computer program and predetermined data, and an external storage device such as a hard disk drive, and a user agent acquisition unit 21, a functional block including a carrier identification information extraction unit 22, a data acquisition unit 23, a link destination information extraction unit 24, a data generation unit 25, and a communication processing unit 26 can be configured.

The user agent acquisition unit 21 acquires a user agent transmitted from the mobile terminal 4.
The user agent is information described as user agent information in the header when the mobile terminal 4 requests distribution of information, and includes carrier identification information that can identify the carrier of the mobile terminal 4. Yes. This user agent is configured, for example, as “carrier identification information / version / model identification information / cache size / individual identification information”, whereby the carrier of the portable terminal 4 can be specified.

  The carrier identification information extraction unit 22 extracts carrier identification information that can identify the carrier of the mobile terminal 4 from the user agent acquired by the user agent acquisition unit 21.

In response to a data acquisition request from the mobile terminal 4, the data acquisition unit 23 reads out and acquires data related to the acquisition request from the Web server 3.
The link destination information extraction unit 24 performs a process of extracting a link property that is link destination data information of a hyperlink included in the data.
The link property includes a URL for linking to data prepared for each carrier, and the URL includes carrier identification information corresponding to the link destination data.
That is, as shown in FIG. 2, “http://example.jp/” common to each carrier is set as the URL of the link destination data of the hyperlink 30 set in the data. For example, pages 31, 32, and 33 corresponding to three types of carriers including A carrier, B carrier, and C carrier are prepared, and the URL of each page corresponds to which carrier the page corresponds to. The carrier identification information indicating whether or not For example, if “http://example.jp/a (carrier identification information) /index.html”, it can be determined from the carrier identification information “A” that the page corresponds to the A carrier.
In the data, the hyperlink is composed of a start tag <A ...> and an end tag </A>, such as “<A HREF=“URL”> character string </A>”. It is described by enclosing a predetermined character string or the like that is an anchor, and information described as the tag corresponds to the link property. In the extraction process, the <A> tag is searched from the data by syntax analysis, and the link property is extracted.

For each hyperlink included in the data, the data generation unit 25, based on the link property extracted by the link destination information extraction unit 24, sets the URL corresponding to the carrier related to the extracted carrier identification information to the link of the hyperlink. A new data generation process is performed by setting the destination URL.
At this time, if the URL of the link destination data corresponding to the carrier of the mobile terminal 4 does not exist, the hyperlink setting is canceled. Canceling the setting of the hyperlink is performed by searching for the <A> tag from the data by syntax analysis and deleting the tag, as in the extraction process by the link destination information extraction unit 24. Thereby, the character string etc. which are the anchors enclosed by the <A> tag are displayed in a text format, for example.

  The communication processing unit 26 performs data transmission / reception processing with the mobile terminal 4 according to a predetermined protocol via the Internet. For example, the communication processing unit 26 performs a process of receiving a data acquisition request from the mobile terminal 4 or transmitting the data generated by the data generation unit 25 to the mobile terminal 4.

The Web server 3 is a computer that accumulates data of a mobile phone site and distributes the data in a WWW (World Wide Web) system.
The data is described in a markup language for mobile phones, such as CHTML, HDML, XML, for example.

The mobile terminal 4 is a mobile phone used by a user of this system. The mobile terminal 4 communicates via a carrier communication network, and performs communication processing unit 41 that performs transmission and reception with the content distribution apparatus 1 via the Internet using a predetermined communication protocol, and a user agent for the mobile terminal 4 as an information processing apparatus. 2, a user agent transmission unit 42 that transmits data to 2, and an output unit 43 that outputs data received from the content distribution apparatus 1 on a display.
Examples of the communication protocol include TCP / IP, UDP / IP, and the like, which are different for each communication carrier.

Next, the flow of processing in the system according to the present embodiment will be described with reference to FIG.
First, the portable terminal 4 transmits a request for acquiring data of a desired site, for example, by inputting a URL to the information processing apparatus 2 by the communication processing unit 41 (S101). At this time, along with the acquisition request, the user agent of the portable terminal 4 is transmitted to the information processing apparatus 2 by the user agent transmission unit 42 (S102).

On the other hand, the information processing apparatus 2 receives the acquisition request by the communication processing unit 26 (S103), and acquires the user agent of the portable terminal 4 by the user agent acquisition unit 21 (S104).
The carrier identification information extraction part 22 extracts the carrier identification information which can identify the carrier of the portable terminal 4 from the acquired user agent (S105).

  On the other hand, in response to the acquisition request, the data acquisition unit 23 reads data associated with the URL address from the Web server 3 that holds the data (S106). The Web server 3 transmits the corresponding data in response to reading from the information processing apparatus 2 (S107).

The information processing apparatus 2 that has acquired the data from the Web server 3 extracts link properties for all hyperlinks included in the data by the link destination information extraction unit 24 (S108). In this extraction process, the <A> tag is searched from the data by syntax analysis, and the link property described by the tag is extracted.
Then, the data generation unit 25 refers to the link property and determines whether or not the URL of the link destination data corresponding to the carrier identification information exists (S109).
As a result, if it is determined that a matching URL exists, the matching URL is set as the link destination URL of the hyperlink (S110). For example, by parsing the data and rewriting the link property described by the <A> tag to a URL corresponding to the user's mobile phone carrier, an appropriate hyperlink is generated and provided. Therefore, the user cannot be accessed and desired information can be accessed.

On the other hand, if it is determined that there is no matching URL, the hyperlink setting is canceled (S112). The hyperlink setting is canceled by, for example, parsing data and deleting the link property described by the <A> tag.
When the setting of the hyperlink is canceled, for example, the underline indicating the hyperlink 51 displayed in the output image of the data before the generation processing by the data generation unit 25 shown in FIG. As shown by 61 in the output image of the data after the generation processing by the data generation unit 25 shown in FIG. Since the hyperlink setting has been canceled, nothing is displayed even if the cursor is designated at 61 in FIG.

  After performing the generation process from S108 to S111 for all the hyperlinks included in the data, the generated new data is distributed to the mobile terminal 4 by the communication processing unit 26 (S112).

  The data distributed in this way is output to a display or the like by the output unit 43 of the mobile terminal 4, and the viewer browses data in which only the hyperlink corresponding to the carrier of the mobile terminal 4 is displayed as the link destination data. (S113), thereby completing a series of processing.

  Thereby, the user who uses the portable terminal 4 does not access a link destination that the portable terminal 4 does not support, and does not have to be bothered.

  In the above embodiment, the new data generation process by the data generation unit 25 cancels the hyperlink setting for a hyperlink that does not have a link destination corresponding to the carrier of the mobile terminal 4. In the data output image, new data may be generated by making the display of the hyperlink distinguishable from the display of other hyperlinks. For example, the color of the hyperlink can be changed from that of another, or the font form can be changed. Such processing can be performed by changing the color designated by the <BODY> tag in the data.

  Further, according to another embodiment of the present invention, the information processing apparatus 2 includes a user agent acquisition unit 21, a carrier identification information extraction unit 22, a data acquisition unit 23, and a link destination information extraction unit 24 as illustrated in FIG. In addition to the data generation unit 25 and the communication processing unit 26, a functional block including a model information storage unit 27, a model identification information extraction unit 28, a specification information specifying unit 29, and an image conversion processing unit 30 can be configured.

The model information storage unit 27 is a storage unit that stores the specification information of the model in association with each model of the mobile terminal 4.
In the model information storage unit 27, for example, as shown in FIG. 7, for each model identification information 71 that can identify the model of the portable terminal 4, a screen size 72, the number of colors 73, which are specification information of the model, a display A possible format 74 is stored. In the screen size 72 column, the maximum displayable size on the display of the mobile terminal 4 is stored, for example, 320 pixels vertically × 240 pixels horizontally. The number of colors 73 column stores the number of colors that can be displayed on the mobile terminal 4 such as 12 bits and 8 bits, and 4096 colors and 256 colors can be displayed, respectively. The displayable format 74 column stores PNG (Portable Network Graphics), GIF (Graphic Interchange Format), and the like as image formats that can be displayed on the mobile terminal 4.
Note that the model identification information is included in the user agent.
By referring to the model information storage unit 27, the specification of the model of the portable terminal 4 can be specified.

  The model identification information extraction unit 28 extracts model identification information that can identify the model of the mobile terminal 4 from the user agent acquired by the user agent acquisition unit 21.

  The specification information specifying unit 29 specifies the model specification information of the mobile terminal 4 with reference to the model information storage unit 27 based on the model identification information extracted by the model identification information extracting unit 28.

  The image conversion processing unit 30 performs processing for converting an image included in the data acquired by the data acquisition unit 23 into an image suitable for the specification information of the portable terminal 4 specified by the specification information specifying unit 29.

Next, the flow of image conversion processing performed in the information processing apparatus 2 in the present embodiment will be described with reference to FIG.
First, similarly to the first embodiment described above, the process up to S107 is followed to acquire data from the Web server 3.

Then, it is determined whether or not image data is included in the data (S201). As a result, when it is determined that the image data is not included, the processing after S109 is performed as in the first embodiment described above.
On the other hand, when it is determined in S201 that the image data is included in the data, the model identification information is extracted by the model identification information extraction unit 28 from the user agent acquired by the user agent acquisition unit 21 (S202).
Then, the specification information specifying unit 29 refers to the model information storage unit 27 and specifies the specification information stored in association with the extracted model identification information (S203).

  The image conversion processing unit 30 converts the image data according to the specification information. In this processing, for example, when the original image is saved in the JPEG (Joint Photographic Experts Group) format with an image size of 320 (vertical) × horizontal 320 (horizontal) (pixels) and a color number of 12 bits (4096 colors). Furthermore, if the specifications of the portable terminal 4 are a screen size of 320 (vertical) × 240 (horizontal) (pixels), a color number of 8 bits (256 colors), and a displayable format is GIF, the image size is set to the screen size. The image size is changed to 240 (vertical) × 240 (horizontal) (pixel) that can be displayed at maximum, the number of colors of the image is changed to 256 colors, and the displayable format is changed to GIF format.

When the image conversion process is performed, the process after S109 in the first embodiment described above is followed, and only the hyperlink in which the URL of the link destination data corresponding to the carrier of the mobile terminal 4 is set is displayed. Data on which an image corresponding to the output specification of the mobile terminal 4 is displayed is distributed to the mobile terminal 4.
Thereby, even if an image is included in the data, the user of the mobile terminal 4 is converted into an appropriate size or the like according to the specifications of the mobile terminal 4 without requiring any operation.
