  FIG. 12 is a sequence diagram illustrating an example of communication processing between the mobile phone and the server when the mobile phone 10 is operated to display a search menu image including keyword ranking information and perform a search. In this example, the mobile phone 10 is a flash-incompatible device, and the display information of the sub menu image constituting the search menu image is newly downloaded from the search service providing server 41 without using the cache data. Yes.

First, the user operates the mobile phone 10 to display the WEB service top page 200 shown in FIG. 13A on the display 104 of the mobile phone 10 (S101).
Next, when the user operates the mobile phone 10 and performs a switching operation to the search menu by selecting the “search” tab displayed at the top of the top page (S102), the mobile phone 10 displays A menu image request including function identification information (in this example, information indicating that the device is not compatible with Flash) is transmitted to the menu server 30 (S103). This display function identification information can be written and transmitted in a header portion in a menu image request in HTTP format, for example.
Upon receiving the menu image request, the menu server 30 carries the display information of the main menu image excluding the display portion of the sub menu image and the URL information of the search service providing server 41 used for acquiring the display information of the sub menu image. A reply is made to the telephone 10 (S104). Here, since the mobile phone 10 is a Flash incompatible device, data in the XHTML format is selected and transmitted as display information of the main menu image.
Next, the cellular phone 10 displays the search menu top screen 201 shown in FIG. 13B based on the display information of the main menu image received from the menu server 30 (S105). However, at this stage, the display area 201a of the sub menu image in the top screen 201 of the search menu is not drawn. Further, the mobile phone 10 provides a search service for a sub menu image request for requesting information on a sub menu image to be drawn in a predetermined area in the top screen of the search menu based on the URL information received from the menu server 30. It transmits to the server 41 (S106). This submenu image request also includes display function identification information.
The search service providing server 41 that has received the sub menu image request returns the display information of the sub menu image to the mobile phone 10 (S107). Here, since the mobile phone 10 is a flash incompatible device, PNG format data is selected and transmitted as display information of the sub menu image instead of the Flash format data. The PNG format data is created so that the display image is the same as that displayed when the Flash format data is displayed.
Next, the mobile phone 10 displays the submenu image in the submenu image display area 201a of the top screen 201 of the search menu shown in FIG. 13B based on the display information of the submenu image received from the menu server 30. Drawing is performed (S108). In the example of FIG. 13B, as the sub menu image, an image showing ranking information from the first place to the third place of current-related content published on the Internet is displayed.

In the above embodiment, the display information of the sub menu image received from the search service providing server 41 may be saved as cache data in the internal memory so that it can be reused.
FIG. 14 is a flowchart illustrating an example of processing in the mobile phone when storing and reusing cache data of display information of the sub menu image. FIG. 15 is a sequence diagram showing an example of communication processing between the mobile phone and the server in this case.
First, similarly to the case of FIG. 12, the mobile phone 10 displays the search menu top screen based on the display information of the main menu image acquired from the menu server 30 (S201 to S204 in FIG. 14 and FIG. 15). S301 to S305).
Next, on the basis of the URL information acquired from the menu server 30, the mobile phone 10 displays the display information of the sub menu image provided by the search service providing server 41 specified by the URL information as cache data within the public validity period. Is determined (S205 in FIG. 14). If there is no cache data for the sub-menu image within the public validity period, the sub-menu image display information is acquired from the search service providing server 41 as in the case of FIG. 12 (S206 in FIG. 14). On the other hand, if there is cache data for the sub-menu image within the public expiration date, the top screen of the search menu shown in FIG. 13B is obtained using the cache data without newly acquiring the display information of the sub-menu image. A submenu image is drawn in the submenu image display area 201a 201 (S207 in FIG. 14 and S306 in FIG. 15).
As described above, when the display information of the sub menu image is stored as cache data within the public validity period, it is determined that there is no change in the display information of the sub menu image, and the sub menu is displayed from the search service providing server 41. Do not get image display information. In this case, the sub menu image is drawn using the display information of the sub menu image already stored in the internal memory. When it is determined that there is no change in the contents of the sub menu image in this way, the display information acquisition process for useless sub menu images is performed by using the display information of the sub menu images already stored in the internal memory. It can be avoided.

In the above embodiment, after the top screen of the search menu is displayed on the mobile phone 10, the search result is displayed and the search is narrowed down as follows.
FIG. 16 is a sequence diagram illustrating an example of processing in the case where search results are displayed and narrowed down search is performed on the top items of the current affairs ranking from the top screen of the search menu displayed on the mobile phone 10 not compatible with Flash.
First, the user operates the mobile phone 10 to select a current event ranking display area 201a that is a sub-menu image portion in the top screen 201 of the search menu in FIG. 13B (S401). With this selection, the cellular phone 10 transmits a sub menu image request for requesting display information of the sub menu image in the XHTML format to the search service providing server 41 (S402).
The search service providing server 41 that has received the sub menu image request returns to the mobile phone 10 display information of the sub menu image in the XHTML format that can individually select and instruct each of the upper items of the current affair ranking (S403).
Next, the mobile phone 10 displays the XHTML format sub menu image received from the search service providing server 41 (S404). When the user selects one of the top items in the current topic ranking in the submenu image (S405), the mobile phone 10 requests a search process for the current keyword (eg, “Tetris”) of the specified item. A search request is transmitted to the search service providing server 41 (S406).
The search service providing server 41 that has received the search request sends a search request including information on the current keyword (for example, “Tetris”) of the designated item to the search server 42, and uses the search result information returned from the search server 42 as XHTML. The data is transmitted to the mobile phone 10 as format data (S407).
Next, the cellular phone 10 displays the search result of the current keyword (for example, “Tetris”) of the designated item received from the search service providing server 41 (S408). On the search result display screen, an input column and a category specification column for auxiliary keywords (auxiliary words) and deletion keywords (deleted words) for narrowing search are also displayed. Here, when the user desires further refinement search, the cellular phone 10 is operated to designate the refinement search condition (S409). Specifically, the narrowing search condition is designated by designating a specific category name or inputting an auxiliary keyword or deletion keyword as the narrowing search condition. When the user instructs the narrow search, the mobile phone 10 transmits a narrow search request including information on the designated category (S410).
The search service providing server 41 that has received the refined search request sends a refined search request including refined search information such as the specified category to the search server 42, and the refined search returned from the search server 42. The result information is transmitted to the mobile phone 10 as data in the XHTML format (S411).
The mobile phone 10 can display the search result of the narrow search for the current keyword (for example, “Tetris”) of the specified item received from the search service providing server 41 (S412).

In the embodiment described above, the display of the search result or the narrowed search after the top screen of the search menu is displayed on the mobile phone 10 can be performed as follows.
For example, when an arbitrary keyword is input in the keyword input field 201b displayed at the top of the top screen of the search menu shown in FIG. 13B and the “Search” button is selected, the search result executed for the input keyword (Content list) can be displayed. In this keyword search, the category can be specified by selecting the category specifying button 201d. In the initial setting, “all menus” in which no category is specified is selected, but when the category specifying button 201d is selected, a category specifying screen 202 for narrowing search shown in FIG. 17A is displayed. On this category designation screen 202, the user can designate a desired category.
When “Chaku-Uta / Ringing Melody” is selected in the “TOP Ranking” field on the top screen of the search menu shown in FIG. 13B, the ring-tone / ringing melody ranking display screen shown in FIG. 203 is displayed. When any item (singer, song title, etc.) in the ranking of the ringtone / ring melody is selected, the selected item is searched for as a keyword, and the search result (content list) as shown in FIG. A screen 204 is displayed. Also on the search result (content list) screen 204, the user can further perform a refinement search by inputting an auxiliary keyword.

  In the above-described embodiment, the case where the mobile phone 10 is a flash incompatible device is shown. However, when the mobile phone 10 is a flash compatible device, a search menu image is displayed and an additional refinement search is performed as follows. .
