  In this embodiment, the functions shown in FIG. 2 and FIG. 3 are realized by the control unit 110 executing a program. For example, an ASIC (Application Specific Integrated Circuit) or the like is used. These functions may be realized by the hardware configuration.

  The above configuration is a configuration necessary for realizing the present invention, and other configurations necessary for basic functions and additional functions as a mobile communication terminal are provided as necessary. To do.

  The operation of the mobile communication terminal 100 configured as described above will be described below with reference to the drawings. In the present embodiment, an example in which an operation of automatically switching from a browser for PC site to a browser for mobile site is performed when a predetermined condition is met when accessing a website using the mobile communication terminal 100 will be described below. explain. First, a switching condition setting process for setting a switching condition desired by the user will be described with reference to a flowchart shown in FIG. This switching condition setting process is started when the user of the mobile communication terminal 100 operates the operation unit 130 to instruct the start of setting of the switching condition.

  When the process is started, the switching condition setting unit 111 displays a setting screen for allowing the user to set the switching condition on the display unit 140 (step S101).

  A display example of the setting screen is shown in FIG. FIG. 5A shows a display example of the initial screen in the setting screen. As shown in the figure, when switching condition setting is instructed, the prepared switching condition items are displayed in a list, and “setting” or “cancellation” is selectably displayed for each item. When “setting” is selected for any item, a detailed setting screen for performing detailed setting for the item as shown in FIG. 5B is displayed on the display unit 140, and a condition desired by the user is input. Is done.

  When the setting content is input for each condition item and an instruction to complete the setting is input through such a setting screen (step S102: Yes), the switching condition setting unit 111 stores the input setting content as setting information. The data is stored in the unit 172 (step S103), and the process ends. In this case, in the setting information storage unit 172, for example, as shown in FIG. 5C, the necessity of application (ON / OFF) and the parameter of the switching condition are recorded for each condition item.

  Next, an operation for switching browsers based on the switching conditions set in this way will be described. As described above, the mobile communication terminal 100 according to the present embodiment is equipped with both a mobile site browser and a PC site browser. Here, it is assumed that the mobile site browsed by the mobile site browser has a smaller amount of content data than the PC site, and its dynamic functions are greatly limited. Therefore, it is assumed that the operation on the PC site browser has a large amount of data on the site, as well as the power consumption during operation and the amount of transmitted packets, compared to the operation on the mobile site browser.

  In such a case, the website browsing process executed when browsing the website with the PC site browser will be described with reference to the flowchart shown in FIG. The website browsing process is started when the user operates the operation unit 130 to instruct the activation of the PC site browser.

  When the process is started, the PC site browser unit 112 is activated to activate the PC site browser, and the browser screen is displayed on the display unit 140 (step S201). When the PC site browser is activated in this manner, the PC site browser unit 112 notifies the operation monitoring unit 113 that the PC site browser has been activated.

  The operation monitoring unit 113 accesses the setting information storage unit 172 in response to the notification from the PC site browser unit 112, and determines whether or not a browser automatic switching condition is set (step S202). Here, in the setting information recorded in the setting information storage unit 172, if there is one or more condition items whose switching necessity (ON / OFF) is ON, it is determined that the automatic switching condition is set. To do.

  When the automatic switching condition is set (step S202: Yes), the operation monitoring unit 113 includes the data capacity monitoring unit 113A, the radio wave state monitoring unit 113B, the communication fee monitoring unit 113C, and the battery remaining amount monitoring unit 113D. The monitoring function corresponding to the set condition item is activated (step S203).

  The user operates the operation unit 130 to input an address (URL (Uniform Resource Locator), etc.) of a site desired to be browsed on the browser screen displayed in step S201, or to specify an address registered in advance. To instruct access to the site. The PC site browser unit 112 accesses the designated website by controlling the communication control unit 120 in response to such an instruction input (step S204).

  When the website is accessed in this way, the operation monitoring unit 113 starts monitoring the operation status of the PC site browser unit 112 by the monitoring function activated in step S203 (step S205).

  The monitoring operation started in step S205 detects the operation status of the PC site browser unit 112 every predetermined time (step S206: Yes, step S207). Then, the numerical value acquired by each monitoring function is compared with the parameters set in the setting information storage unit 172 to determine whether or not the switching condition is satisfied (step S208).

  When the operation status by the PC site browser unit 112 corresponds to the switching condition (step S208: Yes), the operation monitoring unit 113 notifies the browser switching unit 114 to that effect. In response to the notification from the operation monitoring unit 113, the browser switching unit 114 displays on the display unit 140 a switching guide screen for allowing the user to select a selection item related to execution of browser switching (step S209).

  A display example of the switching guide screen is shown in FIG. As shown in the figure, the switching guide screen displays selectable options that the user can take when the set switching condition is met. Here, for example, “switch from browsing for PC site browser to browsing for mobile site browser”, “continue browsing by browser for PC site without switching to browser for mobile site”, “operating browser for PC site” “End and finish browsing” are provided. Such a switching guide screen is displayed in a pop-up on the display screen of the web page that has been browsed so far.

  When such a switching guide screen is displayed, the user operates the operation unit 130 to select a desired option. An input signal indicating the selection operation by the user is input from the operation unit 130 to the control unit 110, and the selection content is determined by the browser switching unit 114.

  Here, when the user's selection is “continuation of PC site browser” (step S210: No, step S211: No), the browser switching unit 114 continues the operation of the PC site browser unit 112. In this case, the browser switching unit 114 accesses the setting information storage unit 172, and cancels the setting for the corresponding switching condition by, for example, changing from ON to OFF (step S212). In this case, the browsing operation on the browser for the PC site is continued by continuously performing the operations after step S202.

  In this case, since the automatic switching condition determined in step S208 is cancelled, automatic switching based on the condition is not performed thereafter. Since other switching conditions are not changed, when multiple switching conditions are set, a separate switching guide screen will be displayed when the operating condition corresponding to each condition is reached. .

  Note that if the setting of all the condition items is canceled by the cancellation in step S212, the operation monitoring unit 113 determines that there is no automatic switching condition setting (step S202: No). In this case, a normal browsing operation by the PC site browser unit 112 is performed until a predetermined end instruction is given (step S213, step S214: No).

  If the detected operating condition does not correspond to the switching condition (step S208: No), the operating condition detection for every predetermined time is continued unless a predetermined end instruction is given (step S215: No).

  Here, for example, when a user operates the operation unit 130 and there is an instruction for ending the browsing operation, or an instruction for ending due to the occurrence of an interruption process due to battery exhaustion or the like (step S214: Yes, step S215: Yes). ), And the process ends accordingly.

  If the user's selection is “end PC site browser” (step S210: No, step S211: Yes), the browser switching unit 114 instructs the PC site browser unit 112 to end the operation. In this case, the processing ends when the PC site browser unit 112 ends the operation.

  As described above, when the set automatic switching condition is satisfied, if switching to the mobile site browser is not desired according to the user's judgment at that time, an operation in accordance with the user's instruction is performed.

  On the other hand, when switching to the mobile site browser under a predetermined condition is selected as set in advance (step S210: Yes), the browser switching unit 114 is used to switch from the PC site browser to the mobile site browser. Browser switching processing is executed (step S300). This browser switching process will be described with reference to the flowchart shown in FIG.

  When the processing is started, the browser switching unit 114 instructs the PC site browser unit 112 to store the address information (URL and the like) of the currently accessed website and the content data. In response to an instruction from the browser switching unit 114, the PC site browser unit 112 saves the address information of the website being accessed in a work area or the like (step S301), and contents data (for example, HTML) of the website. Etc.) is cached in the browser cache unit 174 (step S302).

  Here, when address information (herein, it is assumed to be a URL) is stored, the URL is processed so as to reach the portion indicating the host. That is, the part (path to the content) indicating the resource on the host is deleted and stored. For example, if the URL of the website that you were accessing was "http: //www.+++.com/abc/def.htm", go to "http: //www.+++.com/" Save the part.

  When the storage of the address information and the content data cache are completed, the PC site browser unit 112 notifies the browser switching unit 114 to that effect. In response to the notification from the PC site browser unit 112, the browser switching unit 114 instructs the PC site browser unit 112 to terminate the PC site browser. The PC site browser unit 112 terminates the operation of the PC site browser in response to an instruction from the browser switching unit 114 (step S303).

  The browser switching unit 114 activates the mobile site browser unit 115 in response to the stop of the PC site browser unit 112 (step S304). The browser switching unit 114 instructs the mobile site browser unit 115 to perform access using the address information stored in step S301.

  In response to an instruction from the browser switching unit 114, the mobile site browser unit 115 acquires address information stored in a work area or the like, and controls the communication control unit 120 to attempt access to the address. (Step S305).

  Here, since this address information is the address of the website that the PC site browser unit 112 has accessed, the website is a PC site. Therefore, although the site for PC is prepared in the said site, it is unknown whether the portable site which can be accessed also with the browser part 115 for portable sites is prepared. In the case of a website that has both a PC site and a mobile site, for example, it is determined whether the access is from a mobile communication terminal or from a personal computer based on the type of browser that has been accessed. It is common practice to automatically navigate to a PC site or mobile site. Therefore, if such a site is accessed, the mobile site browser unit 115 is guided to the mobile site, so that the site can be displayed.

  It is common that such an automatically guided web page is placed on the top page of the site. Therefore, when the mobile site browser unit 115 accesses using a URL that has been processed so as to show the host name, if the mobile site is prepared, normal display can be performed. On the other hand, when only the PC site is prepared, the mobile site browser unit 115 tries to display the PC site. However, usually, the functions that can be executed are limited or the description of the source text is different. The mobile site browser unit 115 cannot display normally, resulting in an error.

  Based on such a difference, the mobile site browser unit 115 can determine whether the mobile site is provided on the site accessed by the PC site browser unit 112 (step S306).

  If the mobile site is provided (step S306: Yes), the site accessed by the PC site browser unit 112 can be browsed by the mobile site browser unit 115, so that the browsing can be continued as it is. In this case, since the site can be browsed without using the content data cached in step S302, the PC site browser unit 112 deletes the cache data in the browser cache unit 174 (step S307). The process is terminated. In other words, the browser for the mobile site is switched from the browser for the PC site to continue browsing the website.

  On the other hand, when the mobile site is not provided (step S306: No), the mobile site browser unit 115 cannot continue browsing the site. In this case, as shown in FIG. 8B, the mobile site browser unit 115 makes an inquiry to the user as to whether or not to perform offline display using the cache data of the PC site browsed before switching. An offline confirmation screen is displayed on the display unit 140.

  As shown in the figure, the offline confirmation screen displays whether or not it is necessary to switch to offline display. The user of the mobile communication terminal 100 operates the operation unit 130 and selects a desired operation for offline display.

  When an input signal indicating this selection operation is input from the operation unit 130 to the control unit 110, the browser switching unit 114 determines whether offline display has been selected (step S308).

  When the offline display is selected (step S308: Yes), the browser switching unit 114 activates the PC site browser unit 112 and instructs the offline display using the cache of the browser cache unit 174. In response to an instruction from the browser switching unit 114, the PC site browser unit 112 accesses the browser cache unit 174, performs offline display using the stored cache data (step S309), and ends the process. .

  On the other hand, when the offline display is not selected (step S308: No), the process ends as it is. In this case, the web browsing operation on the mobile communication terminal 100 ends.

  By such an operation, when an operation state corresponding to a preset condition is reached while browsing the PC site with the browser for the PC site, if no exception processing is performed by the user, the browser for the PC site is terminated, and the mobile site Can be switched to the browser. In other words, the operation by the browser for PC site generally requires more power than the operation of the browser for mobile site and requires a good radio wave condition to ensure high-speed communication. When the radio wave condition is poor, the browser for the PC site can be switched to the browser for the mobile site.

  In addition, when browsing the PC site with the browser for the PC site, the amount of packets is larger than when browsing the mobile site with the browser for the mobile site. Therefore, when the communication charge or the packet amount set in advance is reached, the browser for the PC site can be switched to the browser for the mobile site.

  In addition, if the browser for mobile sites cannot be browsed after switching from the browser for PC sites to the browser for mobile sites, the pages accessed by the browser for PC sites are cached and displayed offline using cache data. Therefore, even if the communication with the browser for the PC site is terminated, the content that has been browsed until immediately before can be presented to the user.

  As described above, according to the above-described embodiment of the present invention, it is possible to switch from the operation by the browser for the PC site to the operation of the browser for the mobile site according to an arbitrary condition, and the usage status of the mobile communication terminal Web access can be made efficiently according to

  The said embodiment is an example and the application range of this invention is not restricted to this. That is, various applications are possible, and all embodiments are included in the scope of the present invention.

  In the above embodiment, the browser switching conditions are data amount, packet amount, communication fee, radio wave state, remaining battery level, etc., but these are only examples, and the switching conditions can be arbitrary. Therefore, the configuration of the operation monitoring unit 113 can be set arbitrarily according to the prepared switching condition.

  In the above embodiment, when the operating condition corresponding to the set switching condition is reached, the switching guide screen is displayed to allow the user to make a selection. However, without displaying such a screen, it is automatically performed. It may operate to switch to a mobile site browser.

  In the above embodiment, when the browser is switched, if the mobile site is not provided, the offline display by the cache is performed. However, the condition for performing the offline display is arbitrary and is not limited to this. Absent. For example, when the termination of the PC site browser is instructed by the user's selection, offline display in the cache may be performed.
