【0021】

In practice, CPU 12 built in the mobile terminal apparatus body 15, life power source is stored in the is turned the program memory 13 in accordance with instruction code, and executes a predetermined procedure ST0 shown in FIG. That is, first, the CPU 12 performs the system initialization process of the entire mobile terminal device main body 15 in step ST1. During this system initialization process, the GPS unit 1A finds its own current position at regular time intervals as a check of the current position, including the process of destination registration, and always the latest position information when the CPU 12 needs it. Is set so that

【0022】

Next, in step ST2, CPU12 reads out its own absolute position information from GPS unit 1A, and based on the latest position information obtained, reads out the map information of the surrounding area from CD-ROM device 3 in step ST3, and Fig. 5 It is displayed on the liquid crystal display panel 11 as shown in. Subsequently, the CPU 12 waits for the user to operate the touch panel 10 to request information in the next step ST4, and if there is a user operation, proceeds to step ST5 to perform the user operation process. If there is no user operation or the user operation process in step ST5 is completed, the CPU 12 proceeds to step ST6, monitors the information received by the wireless communication device 4A, and receives a display request from the navigation server 5.

【0023】

If there is a display request from the navigation server 5, the CPU 12 proceeds to step ST7 and displays information on the liquid crystal display panel 11 according to the display request. When this step ST7 is completed or there is no display request from the navigation server 5, the CPU 12 moves to step ST8 and determines whether or not the system is terminated. If it does not end here, the process returns to step ST3, and the process of step ST4 (-step ST5) -step ST6 (-step ST7) described above is repeated from the process of searching and displaying a part of the map information.

【0024】

When the user operates the touch panel 10 to request information in step ST4 described above, the CPU 12 detects it and executes the subroutine of the processing procedure ST10 shown in FIG. 8 as the user operation process in step ST5. That is, the CPU 12 obtains the "request information category and request place name" by the user's operation or the like in step ST11, and transmits this to the navigation server 5 in the subsequent step ST12.

【0025】

Next, in step ST13, the CPU 12 obtains a menu of currently available services obtained from the navigation server 5 based on the "request information category, request place name", and in the following step ST14, displays the menu on the liquid crystal display panel 11. Wait for the user to select. When the user makes some selection input in this state, the process proceeds to the next step ST15, and the selected service determines whether or not further parameter selection is necessary. If further parameter selection is required here, the process proceeds to step ST16 to display a submenu and returns to step ST14. In this way, the CPU 12 receives a menu of services that can be provided from the navigation server 5 according to the request operated by the user, and menus 20, 21, 22 and submenus on the liquid crystal display panel 11 as shown in FIGS. 5 and 6. 23, 24, and 25 are displayed hierarchically in order, allowing the user to enter and select the required information.

【0026】

Then, the CPU 12 repeats this menu and submenu display and the selection input from the user until the necessary information is prepared, and when the necessary information is prepared, the information is sent to the navigation server 5 via the wireless communication device 4A in step ST17. To transfer. When information is sent from the navigation server 5 via the wireless communication device 4A, the CPU 12 acquires the information and displays the information on the liquid crystal display panel 11 as shown in FIG.

【0027】

Figure 9 shows the processing procedure ST20 showing the operation on the navigation server 5 side. In practice, when the communication protocol control means 5A receives the ID, information category, and area information transmitted from the mobile terminal means 2 in step ST21, it starts counting the communication time as billing information processing in step ST22. Further, in the next step ST23, the service inside the service table in the information schema 5C is searched using the information category and the area name as keys, services that can be provided to the mobile terminal means 2 are extracted, and the services that can be provided to the mobile terminal means 2 are extracted and extracted in step ST24. Using the result of, a list of service names and parameter sets is created and transmitted to the mobile terminal means 2, and the request is waited to be transmitted from the mobile terminal means 2.

【0028】

Next, when the navigation server 5 receives the name and parameter set of the specific service transmitted from the mobile terminal means 2 in step ST25, the navigation server 5 refers to the service table in the information schema 5C in step ST26 and changes the name to the service name. After obtaining the corresponding URL (Uniform Resource Locators), access the website 7, 8 or 9 corresponding to the URL on the Internet 6 via the information selection / conversion means 5D, and access the website 7, 8 or 9 corresponding to the URL in HTML (Hyper Text Markup Language) format. Get the service information described in.

【0029】

Next, in step ST27, the HTML-format service information acquired by using the information selection / conversion means 5D is converted and stored as a data table as shown in FIG. 10, which is an element of the service table. Further, in step ST28, a search is performed using the parameter set received in step ST25 as a key from the stored data table, only the information requested from the mobile terminal means 2 is extracted, and then the extraction result is transmitted to the mobile terminal means 2. Then, in step ST29, the information of the service usage fee generated in the series of operations of steps ST21 to ST27 described above is input to the billing DB5B, and the series of processes is completed.

【0030】

Next, the service table 30 and the data table 40 in the information schema 5C will be described with reference to FIGS. 10 and 11 using specific examples. Figure 10 shows an example of the information held in the service table 30 in the information schema 5C inside the navigation server 5. In FIG. 11, 31 is an information category, 32 is a region, 33 is a URL corresponding to each website, 34 is a service name, 35 is a parameter set, and 36 is a data table holding information obtained from each website.

【0031】

For example, if "town information" is sent as the information category and "Tokyo, Kanagawa" is sent as the area from the mobile terminal means 2, the navigation server 5 searches the service table 30 and searches for "town information", "Tokyo, Kanagawa". Extract the services on the 4th and 5th lines that have. The service name 34 and the parameter set 35 are transmitted to the mobile terminal means 2 and are used for display as items of the menu 23, the submenu 24, and the submenu 25 shown in FIG. FIG. 11 shows an example of the information held in the data table 36 of FIG.

【0032】

For example, suppose that "Yokohama" is selected as the location and "Die Hard 3" is selected as the movie name in the submenu 24 of FIG. 5, and the data input time is "9:00". When the location, movie name, and time information is transmitted from the mobile terminal means 2, the navigation server 5 searches the data table 40, extracts the data in the first row, and sends it back to the mobile terminal means 2.

【0033】

【0038】

Embodiment 2. FIG. 15 showing the corresponding portion with FIG. 2 with the same reference numerals shows the internal configuration of the mobile terminal means 2 according to the second embodiment of the present invention. Reference numeral 100 in the figure is a menu information database that stores information on the menu to be displayed on the screen when the user inputs a position. The mobile terminal means 2 in the second embodiment operates by using the information input by the user from the touch panel 10 as the key position information for the search instead of the GPS unit 1A and the antenna 1B in FIG.

【0039】

FIG. 16 is a screen displayed on the liquid crystal panel 11 of the mobile terminal means 2. The user uses this screen to input information on the position where he / she is or the position where he / she intends to go. In the figure, 101 is a main menu that displays the classification of keywords for position search, and 102 is a submenu that presents the user with keywords according to the classification selected in the main menu 101. The items in these menus change at any time according to the user's operation. Furthermore, 112 in the figure is displayed inside 102 and is a direct input area where you can directly enter keywords. 113 is inside the submenu 102 and is a display order specification radio button for specifying the display order of the items in the submenu 102. 104 is a keyword display window for displaying a list of location search keywords entered in the past from submenu 102. Reference numeral 103 denotes a candidate display window that displays candidates for location information searched based on keywords entered in the past.

【0040】

FIG. 17 is an example of a display screen when the user selects destination type from the main menu and selects public facility from the submenu 102 in the main menu. 114 is a checkbox for temporarily disabling or re-enabling the keyword selected from submenu 102. In the figure, the character strings of the selected main menu and submenu are displayed in the keyword display window 103, indicating to the user that the keyword currently in use is "public facility". When some keyword is selected from the submenu 102, the display of the candidate display window 104 is once deleted, and the filtering process by the keyword "public facility" displayed in the candidate window is started.

【0041】

FIG. 18 is an example of the screen display in the state after the completion of the filtering process of FIG. In order to specify the keyword in more detail, the keyword "public facility" in the item of submenu 102 has been moved to the main menu 101, and the item of submenu 102 lists more detailed items. The result of the filtering process of the result of the keyword "public facility" is displayed in the candidate display window 103.

【0042】

FIG. 19 shows the screen display immediately after inputting the character string "Yokohama City" in the direct input area 112 inside the submenu 102 from the state in which "local name" is selected as the main menu 101 from the state of FIG. This is an example. In this way, the keyword can be selected not only from the menu but also the word that becomes the keyword can be directly input using the direct input area 112. The keyword "Yokohama City" is displayed in the keyword display window 104. After that, the display of the candidate display window 103 is deleted once, as in the case where the selection is input from the menu. The filtering process by the keyword "Yokohama" entered in the candidate window is started with the direct word input to the submenu 102 as a trigger.

【0043】

FIG. 20 is an example of the screen display after the completion of the filtering process of FIG. As a result of filtering, the contents of the main menu 101, submenu 102, and candidate window 103 are updated. In addition, the content of the display order specification button 113 inside the submenu 102 has an item "arrange in zip code order" instead of "arrange in order from north". In this way, the display order of the items in the submenu 102 changes depending on what kind of field the items to be displayed belong to.

【0044】

In any of the above situations, the user can select the position information from the candidate display window 103 at any time. When the location information is selected, the CPU 12 starts acquiring the map information from the CD-ROM device 3.

【0045】

FIG. 21 shows the data structure of the elements that are the display items of the main menu and the submenu. In the figure, 200 is an item of the main menu and submenu, and is an element object consisting of a display character string of the item and the like. 201 is pointer information to the element object that is displayed as an item in the main menu above it when the element object 200 is displayed in the submenu. 202 is the display character string that is actually displayed on the screen when the element object 200 is selected as an item in the main menu or submenu. 203 is a list of sort methods for sorting other element objects displayed in the submenu when the element object 200 is displayed as an item in the main menu. 204 is a list of sort keys used as display order keys when the Element Talent 200 is displayed in the submenu.

【0046】

22 and 23 are diagrams illustrating how the element objects are organized inside the menu information database. The element object 200 constitutes a tree structure as shown in the figure by a hierarchical relationship based on a pointer 201 to another element object. In the figure, 210, 211, and 214 are the top-level element objects displayed in the main menu on the initial screen. In addition, the existence of an element object having a plurality of upper element objects such as the element object 213 having "Yokohama" as a display character string is also allowed. However, the tree structure composed of the top-level element objects is not allowed to have element objects in common with each other.

【0047】

In practice, the CPU 12 built into the mobile terminal device 15 follows the instruction code stored in the program memory 13 when the power is turned on, and the same steps as those in FIG. 7 are designated by the same code as shown in FIG. 24. To execute. That is, first, the CPU 12 performs all initialization processing of the mobile terminal device main body 15 in step ST1. In this initialization process, the CPU 12 also performs the initial screen configuration process. That is, the top-level element object is acquired as an item of the main menu 101, the number of keywords in the search keyword display window 104 is set to 0, and the items in the candidate display window 103 are displayed in the order in which they have been used in the past.

【0048】

In the next step ST222, the user waits for the operation of the touch panel 10. After the reference position is determined by the user's operation, ST3 to ST9 are executed using this position information as a key. In step ST222 described above, the CPU 12 executes the subroutine of the processing procedure ST230 shown in FIG. 25 as the position acquisition process. First, it is determined whether or not the target operated by the user in step ST231 is the main menu 101, and if it is correct, the process moves to the main menu selection process ST232 and then returns to step ST230.

【0049】

When the main menu 101 is not operated by the user in step ST231 It is determined whether or not the user operated the submenu 102 in step ST233, and if it is correct, the process moves to the submenu selection process ST234. After that, the process returns to step ST230 again. When the user operated in step ST233 is not the submenu 102. In step ST235, the user operates the search keyword display window 104. If it is correct, the search keyword display window processing ST236 After moving to, return to step ST230 again.

【0050】

In step ST235, if the search keyword 104 is not operated by the user, it is determined whether or not the candidate display window 103 is operated by the user in step ST237, and if it is correct, the next step is performed. In ST238, the position information acquisition process is started, and in step ST239, the subroutine is terminated. If it is determined in step ST237 that the user has not operated the candidate display window 103, step ST230 waits for the user's input again.

【0051】

When the main menu selection process is executed in step ST232 described above, the CPU 12 executes the subroutine of the process procedure ST240 shown in FIG. That is, in step ST241, the CPU 12 acquires the element object 200 corresponding to the main menu item selected by the user, and in ST242, the CPU 12 subordinates all the element objects having the acquired element object as the upper element object in the information pointer 201. Selected as an element object for the menu 102 configuration, in step ST243, the element objects for the submenu configuration are sorted by the sort method of the element object acquired in ST241, and in step ST244, based on the result of sorting in ST242. The display character string 202 of each element object of the element object group for the submenu 102 configuration selected in ST242 is displayed on the submenu 102.

【0052】

When the submenu selection process is executed in step ST234 described above, the CPU 12 executes the subroutine of the process procedure ST250 shown in FIG. 27. That is, the CPU 12 acquires the element object 200 corresponding to the selected menu item in step ST251. Subsequently, in step ST252, the display character string 202 possessed by the element object acquired in step ST251 is added to the display items of the search keyword display window, and in step ST253, it is the upper element object of the element object acquired in step ST251 and is the main. Remove the element object for which the display character string 202 is displayed in the menu from the items of the main menu 101.

【0053】

Further, in step ST254, the CPU 12 adds the display character string 202 of the element object acquired in step ST251 to the item of the main menu 101 in place of the element object removed in step ST253. Subsequently, in step ST255, the CPU 12 selects the element object acquired in step ST251 as a higher-level element object and all the element objects in the information pointer 201 as element objects for submenu configuration. Next, in step ST256, the element object group for submenu configuration is sorted by the sort method of the element object acquired in ST251, and in step ST257, it is selected in step ST255 based on the result of sorting in step ST256. The display character string 202 of each element object of the element object group for the submenu 102 configuration is displayed on the submenu 102, and in step ST258, the step is taken against the list of candidates held by the candidate display window 103. The search process is performed using the display character string 202 of the element object acquired in ST251 as a key, and the result is reflected in the display of the candidate display window 103.

When the search keyword display window selection process is executed in step ST236 described above, the CPU 12 executes the subroutine of the process procedure ST260 shown in FIG. 28. That is, in step ST261, the CPU 12 acquires the keyword corresponding to the check box 114 removed from the search keyword display window, and in step ST262, the keyword acquired in ST261 from the contents of the main menu 101 is before being specified by the user. Return to the state, in step ST263, initialize all the contents of the submenu 102, and in step ST264, the candidates obtained as a result of removing the keyword acquired in ST261 from the candidate list held by the candidate display window 103 from the search key and searching. Change to a list.
