JP4791926B2 - Web page storage management method and information communication terminal device - Google Patents

Description

  The present invention relates to a web page storage management method and an information communication terminal device that can use the web page storage management method.

  Conventionally, information communication terminal devices such as mobile phone devices have been widely used. In recent years, with the improvement of functions of information communication terminal devices, in addition to the call function and e-mail transmission / reception function, information communication terminal devices having a web browser function for browsing web pages published on the Internet have become widespread. Progressing.

  Such web browser functions include a full browser function adopted in general information communication terminal devices such as personal computers, and a simple browser function adopted in many small information communication terminal devices such as mobile phone devices. However, the mounting of full browser functions is also progressing in mobile phone devices and the like. 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 browser display area where an image is displayed by the web browser function is divided into a plurality of areas, and a separate web page is displayed in each of the divided areas. In this case, each area is divided.

  In an information communication apparatus having such a frame function, frame configuration information and a web page corresponding to each frame (hereinafter also referred to as “frame page”) are obtained from a web server. In the information communication device, the browser display area is divided based on the frame configuration information, and a corresponding web page image is displayed in each divided area (see Patent Document 1). Each of the frame configuration information and the web page information corresponding to each frame includes information related to the update.

  Incidentally, a web page storage function for storing a web page displayed on the screen of the information communication terminal device is generally prepared as one of the web browser functions described above. Web pages once saved using this web page saving function are widely used because they can be viewed even in an environment not connected to the Internet, that is, in an offline state.

  When performing web page saving in a state where a plurality of frames are displayed using such a web page saving function, it is generally performed to save frame configuration information and all frame pages at that time ( Hereinafter referred to as “conventional example”). This is because the display in the browser display area at the time of saving can be reproduced from the saved information at the time of saving.

Then, the web page storage processing unit 37 stores new individual display page identification information at the display page identification information position in the new individual index information.

  On the other hand, when the report from the identification information collation determination unit 36 indicates that the same entity information as the entity information of the currently displayed web page is not stored, the web page storage processing unit 37 displays the current display. The entity information of the inside web page is stored in the entity information 28 of the storage unit 25, and new individual display page identification information associated with the entity information of the newly stored web page is created. Then, the web page storage processing unit 37 stores the new individual display page identification information at the display page identification information position in the new individual index information.

  If the currently displayed web page has a frame configuration and the entity information corresponding to all the frame pages has already been saved, the web page save processing unit 37 has already saved and is currently displayed. The individual display page identification information corresponding to the middle page is used as it is to create new individual display page identification information. Then, the web page storage processing unit 37 stores new individual display page identification information at the display page identification information position in the new individual index information.

  When the currently displayed web page has a frame configuration and no entity information corresponding to the frame page is stored, the web page storage processing unit 37 stores the web page currently being displayed. All the entity information is stored in the entity information 28 of the storage unit 25, and new individual display page identification information associated with the entity information of the newly stored frame page is created. Then, the web page storage processing unit 37 stores new individual display page identification information at the display page identification information position in the new individual index information.

  If the currently displayed web page has a frame structure and entity information corresponding to some frame pages is already stored, the web page storage processing unit 37 stores the unstored entity. Information is stored in the entity information 28 of the storage unit 25. Subsequently, the web page storage processing unit 37 updates the individual display page identification information that is already stored and corresponds to the currently displayed page so that the newly stored entity information is associated with the new individual display. Create page identification information. Then, the web page storage processing unit 37 stores new individual display page identification information at the display page identification information position in the new individual index information.

[Operation]
Next, in the mobile phone device 10 configured as described above, the processing when the web browser program 30 stores a web page displayed in a frame will be mainly described. It is assumed that the web browser program 30 has already started processing. Further, it is assumed that a frame as shown in FIG. 11 is displayed on the display unit 13, and web pages having different URLs are displayed on the frames FR1 to FR3.

  In the web page storage process in the mobile phone device 10, as shown in FIG. 12, first, in step S11, the identification information collation determination unit 36 of the browser control unit 34 operates the operation unit 12 by the user of the communication terminal device. To determine whether or not a save event to save the web page has occurred. If the result of this determination is negative (step S11: N), the process of step S11 is repeated until the save 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 identification information collating / determining unit 36 analyzes the root page in which the frame configuration information is described, and acquires the URLs of all web pages displayed in each frame. Subsequently, in step S13, the identification information collation determination unit 36 acquires display page identification information of each URL. The display page identification information acquired at this time is assumed to be version information that changes according to the last update date and time of the frame page indicated by each URL and the content of the frame page. It is obtained by referring to the “Last-Modified” header and the “ETag” header included in the response content of the web server.

  Next, in step S14, the identification information collation determination unit 36 determines whether or not the same entity information as each of the frame pages displayed in the frame is already stored. When determining whether to store the entity information, the identification information collation determination unit 36 first determines whether or not the individual display page identification information in which the same URL as the URL of the root page being displayed is stored is stored. If the result of the determination of the root page URL identity is negative, the identification information collation determination unit 36 determines that no entity information of the currently displayed frame page is stored.

  If the determination result of the root page URL identity is negative, the determination process shown in FIG. 13 is performed for each frame page displayed in the frame. That is, in step S21, it is determined whether or not the same URL as the URL of the frame page displayed in the frame is stored in the display page identification information 27. When this determination is negative (step S21: N), the identification information collation determination unit 36 sets a return value “1” in step S25. On the other hand, when the result of this determination is affirmative (step S21: Y), the process proceeds to step S22.

  In step S <b> 22, the identification information collation determination unit 36 further determines whether or not the last update date / time of the frame page matches. This determination is made based on the value of the “Last-Modified” header. When this determination is negative (step S22: N), in step S25, the identification information collation determination unit 36 sets a return value “1”. On the other hand, when the result of this determination is affirmative (step S22: Y), the process proceeds to step S23.

  In step S23, the identification information collation determination unit 36 further determines whether or not the web page version information matches. This determination is made based on the value of the “ETag” header. If this determination is negative (step S23: N), the identification information collation determination unit 36 sets a return value “1” in step S25. On the other hand, if the result of this determination is affirmative (step S23: Y), the identification information collation determination unit 36 sets a return value “0” in step S24.

  The result of the determination in step S14 performed as described above is reported to the web page storage processing unit 37.

Returning to FIG. 12, if the result of the determination in step S14 is affirmative (step S14: Y), the process proceeds to step S15. In step S15, firstly, the web page storage processing unit 37, creates a new individual index information about the web page information to be newly stored, by referring to the latest saved index position 26 _0, saving page index information 26 Save to. Subsequently, the web page storage processing unit 37 creates new individual display page identification information by using the individual display page identification information in the storage unit 25 that is the basis of the determination in step S14 as it is. Then, the web page storage processing unit 37 stores the new individual display page identification information in the position of the display page identification information in the new individual index information.

If the result of the determination in step S14 is negative (step S14: N), the process proceeds to step S16. In step S16, firstly, the web page storage processing unit 37, creates a new individual index information about the web page information to be newly stored, by referring to the latest saved index position 26 _0, saving page index information 26 Save to. Subsequently, the web page storage processing unit 37 stores the entity information determined not to be stored in the entity information 28 of the storage unit 25. Then, the web page storage processing unit 37 associates (links) the newly stored entity information with the already stored entity information when there is already stored entity information for the display frame page. ) Create new individual display page identification information. The web page storage processing unit 37 stores the new individual display page identification information thus created at the display page identification information position in the new individual index information.

  If the web page for which the save command has been issued does not have a frame configuration, the web page is saved in the same manner as when only the root page is displayed.

  After executing the storage processing of the web page displayed in the frame as described above, when a frame display reproduction command is given via the operation unit 12, the browser control unit 34 displays the stored frame-displayed web page. The page information is read from the storage unit 25. Specifically, the browser control unit 34 first reads the individual index information corresponding to the frame display designated by the frame display reproduction command. Subsequently, the browser control unit 34 reads the individual display page identification information with reference to the display page identification information position in the read individual index information. Then, referring to the entity information position in the individual display page identification information, the page entity information of each frame to be displayed in a frame is read.

  Based on the individual index information, the individual display page identification information, and the page entity information of each frame thus read out, the browser control unit 34 reproduces the display image data of all frames at the time of storage. The display image data of all frames reproduced in this way is sent to the display control unit 33. As a result, the frame display at the time of the storage is accurately reproduced and displayed on the display unit 13.

  As described above, in the present embodiment, when a web page storage event including a plurality of frames displayed in the display area of the information communication terminal device occurs in accordance with the operation of the operation unit 12, the identification information collation determination is performed.
