However, mounting of a full browser function is also progressing in mobile phone devices and the like (see Patent Document 1). One of the differences between the simple browser function and the full browser function is whether or not the frame function is supported. Here, the “frame” is a layout in which a display area by the web browser function is divided into a plurality of areas, and a separate web page (frame page) is displayed in each of the divided areas. Each divided area.

  One of the functions provided in the above-described web browser function is a web page update function for updating the content of the web page displayed on the screen of the information communication terminal device to the latest content. When the content of a frame page displayed in a frame is updated using such a web page update function, first, a web page including frame configuration information (hereinafter referred to as “root page”) is reacquired, and then Based on the frame configuration information included in the re-acquired root page, all the frame pages displayed in each frame are re-acquired. Therefore, it is necessary to perform more communication between the information communication terminal device and the web server than when a web page that is not displayed in a frame is updated.

  In addition, the conventional general web browser function often performs the same processing as described above even when it is desired to update only the frame page displayed in a part of a plurality of frames. As a result, all frame pages including the root page are reacquired, and not only a lot of communication is performed between the information communication terminal device and the web server, but also a long time until the entire web page is redisplayed. Needed.

  In response to an instruction from the update determination unit 36, the update unit 37 acquires the latest content of the frame page to be updated to the latest content using the communication unit 31 and the analysis unit 32. Then, the update unit 37 causes the display unit 13 to display a frame display reflecting the acquired latest content via the display control unit 33.

Returning to FIG. 2, the storage unit 25 stores the intra-frame page update information 26 as described above. The intra-frame page update information 26 stores information for determining whether or not the web page displayed in each frame area after the root page is acquired. For example, as shown in FIG. 4, when the display area of the web page in the display unit 13 is divided into three frames FR1 to FR3, the intra-frame page update information 26 is shown in FIG. 26 ₁ , 26 ₂ , and 26 ₃ , which are values corresponding to the above-described FR1 to FR3, are stored.

[Operation]
Next, in the mobile phone device 10 configured as described above, the processing when the web browser program 30 updates a web page displayed in a frame will be mainly described. It is assumed that the web browser program 30 has already started processing, and the display unit 13 displays a frame as shown in FIG. In addition, the intra-frame page update information 26 ₁ , 26 ₂ , and 26 ₃ corresponding to the above-described FR1 to FR3 is already stored in the intra-frame page update information 26 in the state shown in FIG. .

  In the web page update process in the mobile phone device 10, as shown in FIG. 6, first, in step S 11, the browser control unit 34 displays the frame-displayed web by the operation of the operation unit 12 by the user of the communication terminal device. It is determined whether or not an update event for updating the page has occurred. If the result of this determination is negative (step S11: N), the process of step S11 is repeated until the update event occurs. On the other hand, when the result of this determination is affirmative (step S11: Y), the process proceeds to step S12.

In step S12, the update determination unit 36 of the browser control unit 34 determines whether or not there is a frame page for which a page change has occurred before the update event occurs. In this determination, the update determination unit 36 refers to the intra-frame page update information 26 and determines whether or not there is at least one frame page in which a page change has occurred before an update event occurs. This determination is performed by determining whether the value stored in the intra-frame update information 26 ₁ , 26 ₂ , 26 ₃ ,... Is “0” or “1”.

For example, in FIG. 5 (B), the since the value of the frame in the update information ₂₆₁ is "1", the frame page displayed in a frame region of FR1 shown in FIG. 4, the update event This indicates that the page has been changed before it occurred. On the other hand, since the values of the intra-frame update information 26 ₂ and 26 ₃ are “0”, the frame page displayed in the FR2 and FR3 areas has not been changed before the update event occurs. It shows that. Therefore, in FIG. 5B, since the content of FR1, which is at least one of FR1 to FR3, has been changed, the determination result is affirmative. If the result of this determination is affirmative (step S12: Y), the process proceeds to step S13.

  In step S13, the content of the web page displayed in the frame in which the value of the intra-frame update information 26 is “1” is updated to the latest content. Specifically, the update determination unit 36 issues an instruction to the update unit 37 to update the content of the web page that has been changed before the update event occurs to the latest content. The update unit 37 that has received this instruction acquires the latest content using the communication unit 31 and the analysis unit 32, and displays the frame display reflecting the acquired latest content via the display control unit 33. 13 is displayed.

  Subsequently, in step S14, the update determination unit 36 determines whether there is another web page whose page has been changed before the update event occurs by searching the value of the in-frame update information 26. Until this determination is negative, the processes of steps S13 to S14 described above are repeated.

  On the other hand, when the result of the determination in step S12 is negative (step S12: N), the process proceeds to step S15. In step S15, the content of the web page displayed in all frames is updated to the latest content. Specifically, the browser control unit 34 re-acquires all the web pages currently displayed in the frame. Thereafter, the process proceeds to step S11, and the processes in steps S11 to S15 described above are repeated until the web browser program 30 ends.

  As described above, in the present embodiment, the update determination unit 36 when an update event of a web page including a plurality of frames displayed in the display area of the information communication terminal device occurs with the operation of the operation unit 12. However, it is determined whether or not there is at least one web page whose page has been changed before the update event occurs. If the result of this determination is affirmative, the update unit 37 updates the web page on which the page has been changed to the latest content using the communication unit 31 and the analysis unit 32.

  Therefore, according to the information communication terminal device of the present invention, it is possible to rationally reduce the communication amount in updating the display of a plurality of web pages in the frame display.
