The communication unit 6 includes a radio unit, a baseband unit, a demultiplexing unit, and the like, for example, for transmitting and receiving data to and from the nearest base station during the operation of the call function, the e-mail function, and the Internet connection function. During operation of the call function, a signal is acquired from the receiving side of the baseband unit and demodulated into a received baseband signal, and then the sound is output from the speaker SP for calling via the telephone unit 7, and the input sound from the calling microphone MC is also output. Data is fetched from the telephone unit 7 and encoded into a transmission baseband signal, which is then given to the transmission side of the baseband unit and transmitted from the antenna.

FIG. 2 is a diagram for explaining data (function / setting menu) stored in a hierarchical structure.
This function / setting menu includes, for example, a function menu for selecting a function such as network service / answering service / call forwarding service, and a setting menu for setting a notification method. A setting menu for setting the method is shown. That is, the data (menu item) of “call charge”, “sound / vibration / LED”, “screen display / lighting”,... Belongs to the highest hierarchy following the route, and this “sound / vibration / LED”. The menu items “Normal incoming call”, “E-mail reception”, “Receive notification”, “C-mail reception”,... Belong to the lower layer following “”. Each menu item of “Volume”, “Melody”, “Vibrator”, “LED setting” belongs, and “Volume”, “Melody”, “Vibrator”, “LED setting” are in the lower hierarchy after “C-mail reception”. ”And“ Time ”menu items belong to each other.

FIG. 3 is a view showing a display example for explaining a process until various sound volumes are set using the function / setting menu shown in FIG.
FIG. 3 (1) shows a display screen when the function / setting menu is selected, and the main screen MD displays a list of menu items in the highest hierarchy. In the example shown in the figure, for example, “Sound / Vibration / LED” is selected as the desired item from the list display of the main screen MD, and the highlighted data in the figure is selected. Data are shown (the same applies hereinafter).

The search input area (search window) SW constitutes a search function, and a keyword (search character string) for searching data (function / setting menu in the illustrated example) stored and managed in a hierarchical structure is provided. Entered. That is, a keyword that is directly input by a user operation is input to the search window SW, and the keyword is extracted from the function / setting menu as a search character string and displayed. Note that inputting a keyword into the search window SW is synonymous with entering a keyword into the search function. In the function / setting menu of FIG. 2, a character string (sound volume) marked with a circle indicates a part of the extracted keyword (the same applies to FIGS. 12 and 14 described later).

In this case, when there is a menu item belonging to the lower hierarchy in the selected menu item, the control unit 1 sets a keyword (search character string) for searching for the menu item belonging to the lower hierarchy as a predetermined condition. Extract according to (see FIG. 4). FIG. 4 is a diagram for explaining keyword extraction conditions. As keyword extraction conditions in the function / setting menu, for example, as an excluded character string, set / not set / display / not display ... particles and auxiliary verbs are set. Also, setting / incoming / reception,... Are set as character strings that are not divided into front and rear. For example, if the character string is “LED setting”, the character string that is not divided before and after indicates that it is not divided into “LED” and “setting”.

In this case, according to the selection of “sound / vibration / LED”, “volume”, “melody”, “vibrator”, “LED setting”,... Is done. Here, the keywords “volume”, “melody”, “vibrator”, “LED setting”, etc. associated with “sound / vibration / LED” of the selected menu item are set according to the extraction flag described later. It is stored in the keyword table KT of FIG. This keyword table KT stores each keyword extracted from data belonging to a lower hierarchy of data selected from a plurality of data stored and managed in a hierarchical structure and a priority order for determining the ranking of each keyword. In the example of FIG. 5, each keyword extracted from the lower hierarchy corresponding to “call charge”, “sound / vibration / LED”, “screen display / lighting”,. This is the case.

The keywords extracted as described above are displayed in the search window SW. In the illustrated example, “volume”, “melody”, and “vibrator” are scrolled and displayed in the search window SW in that order. The case is illustrated. In this case, whether the extracted keywords are scroll-displayed in the search window SW in accordance with the above-described order of priority or whether only the top-priority keywords are displayed in the search window SW (highest priority display) is arbitrarily determined in advance. In the illustrated example, the case of scroll display is shown. If the above-mentioned highest priority display is selected, for example, only “volume” is fixedly displayed in the search window SW as the highest priority keyword.

FIG. 3 (2) shows that when the search window SW is selected by a user operation so that the search window SW can be used, each keyword extracted as described above is displayed as a pull-down menu according to the order of priority. It is the figure which showed the state displayed as a list. In the illustrated example, this pull-down menu PM is a case where “volume”, “melody”, “vibrator”, “LED setting”,... Are listed in that order. FIG. 3 (3) illustrates the case where “Volume” is selected from the pull-down menu PM. The selected “Volume” is input and displayed in the search window SW, and the main screen MD is displayed. On the front side, another screen WD is superimposed and displayed as a search result display screen. In this case, on the separate screen WD as a search result display screen, “normal incoming”, “email received”, “notice received”, and “C mail received” are displayed as search results. In this case, even if there is a menu related to “volume” in the lower layer of “screen display / lighting” of the menu item shown in FIG. 2 on another screen WD for displaying the search result, this time Since it is not a lower hierarchy of “Sound / Vibration / LED” of the selected menu item, “Volume” in a lower hierarchy of “Screen display / Lighting” is not displayed.

Next, the operation concept of the mobile phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This also applies to other embodiments described later, and in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 6 is a flowchart (main flow) showing the overall operation of the mobile phone device that is started when the power is turned on.
First, after initial setting such as clearing a predetermined memory (step A1 in FIG. 6), the control unit 1 enters a standby state while reading and displaying a predetermined standby image (step A2). In this standby state, the presence or absence of an incoming call from the communication unit 6 is checked (step A3). When an incoming call is detected, in response to an off-hook operation for connecting a line (YES in step A4), a call process for making a call ready state Is executed (step A5), and thereafter, in response to an on-hook operation for blocking the line (YES in step A6), line blocking processing is performed (step A7). And it returns to the standby state of the above-mentioned step A2.

In the standby state, when a selection operation for displaying the function / setting menu and instructing the selection of the function / setting is performed (YES in step A8), the process proceeds to a function / setting process described later (step A9). When a selection operation for selecting a desired folder / file from a plurality of folders / files is performed (YES in step A10), the process proceeds to a folder / file process described later (step A11). When a selection operation for selecting an e-mail to be browsed is performed (YES in step A12), the process proceeds to an e-mail process described later (step A13), and when other operations are performed (YES in step A14), As processing according to the operation, for example, voice call transmission processing or the like is performed (step A15).

FIG. 7 is a flowchart for explaining the function / setting process (step A9 in FIG. 6) in detail.
First, the control unit 1 displays a function / setting menu in response to a function / setting selection operation (step B1). In this case, as shown in FIG. 3 (1), the main screen MD displays a list of menu items in the highest hierarchy, and when an operation for selecting any of the menu items is performed in this state (step) If the selection item has a lower hierarchy (step B3), if there is no lower hierarchy, the process proceeds to step B21. If there is a lower hierarchy (YES in step B3), the search item is searched. With reference to the extraction flag indicating the timing for extracting the keyword, it is checked whether the value is “1” (step B4). FIG. 15 (1) is a diagram for explaining an extraction flag. “0” indicates that a keyword is extracted when a function / setting is selected, and “1” indicates that a keyword is extracted when a function / setting is added. It is stored in the keyword table KT. The extraction flag can be freely set at any time by a user operation, and the contents thereof can be changed as necessary.

If the extraction flag is “1” (YES in step B4), each keyword stored in the keyword table KT is referred to (step B5), and a keyword list in an arrangement order corresponding to the priority order is generated. (Step B6). In this case, the priority order is the order in which the keywords are selected in the descending order, and a list of keywords corresponding to the order of selection times is generated. Then, it is checked whether the highest priority display flag is “1” (step B7). Here, FIG. 15B is a diagram for explaining the highest priority display flag. “0” indicates that the keywords extracted for search are scroll-displayed in the search window SW according to the arrangement order according to the priority. “1” indicates that the highest priority keyword is fixedly displayed in the search window SW. The highest priority display flag can be freely set at any time by a user operation, and the contents thereof can be changed as necessary.

If the highest priority display flag is “1” (YES in step B7), the highest priority keyword is fixedly displayed in the search window SW (step B8), but if it is “0” (NO in step B7). Each keyword is scroll-displayed in the search window SW according to the order of arrangement according to the priority order (step B9). On the other hand, if the extraction flag is “0” (NO in step B4), a keyword for searching for a menu item belonging to a lower hierarchy of the selected menu item is extracted according to the keyword extraction condition of FIG. B10) With reference to the number of selections (priority order) associated with each keyword, the order of the selection is determined based on the number of selections (step B12). Then, the process proceeds to step B6 described above, and after generating a keyword list, each keyword is scroll-displayed according to the highest priority display flag or the highest priority keyword is fixedly displayed (steps B7 to B9).

When an addition operation for adding a new item to the function / setting menu is performed (YES in step B13), a process for adding a new item is executed (step B14), and the extraction flag is referred to. Whether the value is “1” is checked (step B15). If it is “1”, the newly added item is also included in the extraction target and the keyword extraction process is performed (step B16). That is, keywords for searching for menu items that belong to the lower hierarchy of the selected menu item are extracted according to the keyword extraction conditions of FIG. 4, stored in the keyword table KT, and their contents are updated (step B17).

Further, as other operations, it is checked whether a selection operation for selecting the search window SW and making it active is performed (step B18), or whether an end operation for closing the function / setting menu is performed. (Step B19). Now, when the function / setting menu end operation is performed (YES in step B19), the process returns to the standby state (step A2 in FIG. 6), but when the search window selection operation is performed (YES in step B18). The process proceeds to search operation processing (step B20).

FIG. 8 is a flowchart for explaining the search operation process (step B20 in FIG. 7 and the like) in detail.
First, the control unit 1 displays a list of keywords generated as described above as a pull-down menu PM as shown in FIG. 3B (step C1). Whether an operation for selecting a keyword from the pull-down menu PM has been performed (step C2) or whether an operation for inputting a keyword from the operation unit 5 has been performed (step C7). If there is, after inputting the keyword into the search window SW (step C8), a keyword belonging to the function / setting menu below the currently specified hierarchy is searched based on the keyword (step C9).

As a result, if there is no corresponding menu item (NO in step C10), the process returns to the above-described step C2, but if there is a corresponding menu item (YES in step C10), a search as shown in FIG. The result is displayed (step C5). If the keyword is selected from the pull-down menu PM (YES in step C2), after the selected keyword is input to the search window SW (step C3), the function / setting menu is searched based on the keyword (step S3). C4), the search result is displayed (step C5). When a desired item is selected from the search results in the state where the search results are displayed in this way (step C6), the flow returns to the flow of FIG.

When the search operation process (step B20 in FIG. 7) is completed as described above, the extraction flag is referred to to check whether the value is “1” (step B21). The number of selected functions / settings (priority order) is updated and stored in the keyword table KT (step B22). Thereafter, after displaying the function / setting screen (step B23), the function / setting process is executed (step B25) according to the function / setting operation (step B24). Thereafter, the process shifts to a standby state (step A2 in FIG. 6).

FIG. 9 is a flowchart for explaining the folder / file processing (step A11 in FIG. 6) in detail.
First, the control unit 1 displays a list of folders / folder names in response to a folder / file selection operation (step D1). FIG. 11 is a display example for explaining a process until a desired file is selected from folders / files, and FIG. 11 shows a display screen when a data folder is selected. This data folder is stored and managed in a hierarchical structure as shown in FIG. 12, and each main folder MD has, for example, “all data”, “travel”, “rackby” as the name of each folder in the highest hierarchy. , ... are displayed in a list.

When an operation for selecting a desired folder / file name from the main screen MD is performed (YES in step D2), it is checked whether a folder is selected (step D3). Now, when a folder is selected, since there is a lower hierarchy in the folder, the process moves to step D4, and a keyword (search character string) for searching for a folder / file belonging to the lower hierarchy of the selected folder. Are extracted according to a predetermined condition (see FIG. 4) (step D4).

In this case, as shown in FIG. 4, excluded character strings (particles, auxiliary verbs) are set as keyword extraction conditions corresponding to folders / files, and keyword extraction is performed according to these conditions. At that time, it is extracted from the folder name / file name. In the case of a text file, the text content (character string) is also extracted, and in the case of an image, music, or moving image file, it is added to it. Character strings added to the data are also extracted. At that time, after performing morphological analysis on the character string to be extracted and dividing it into elements, a character string satisfying the keyword extraction condition is extracted as a keyword.

Then, the appearance frequency of the extracted keyword is obtained, the priority order of each keyword is determined according to the appearance frequency (step D5), and a keyword list according to the order of the priority order is generated (step D6). If the highest priority display flag is “1” (YES in step D7), the highest priority keyword is fixedly displayed in the search window SW (step D8), but if it is “0” (NO in step D7). ), The respective keywords are scroll-displayed in the search window SW in accordance with the arrangement order according to the priority order (step D9). In the case of FIG. 11 (1), “travel”, “Hokkaido”, “ryokan”,... Are scrolled and displayed in the search window SW according to the order.

Further, as other operations, it is checked whether a selection operation for selecting the search window SW and making it active is performed (step D10), or whether a closing operation for closing a folder / file is performed (step D10). Step D14). Now, when a folder / file end operation is performed (YES in step D14), the process shifts to a standby state (step A2 in FIG. 6), but when a search window selection operation is performed (YES in step D10), FIG. The process proceeds to the search operation process shown in FIG. 8 (step D11). As a result, a list of keywords is displayed as a pull-down menu PM as shown in FIG. 11B (step C1 in FIG. 8).

When a keyword is selected from the pull-down menu PM (step C2), search processing is executed accordingly (steps C3 and C4), and as shown in FIG. The search result is displayed on the matching separate screen WD (step C5). In this search result another screen WD, “travel as a keyword that may exist in a lower hierarchy of“ Rackby ”in the same hierarchy as the currently selected“ travel ”is not displayed. Unnecessary information is not given to the user, and when an arbitrary file is selected from such a search result (step C6), the search operation process proceeds to step D12 in FIG. When the operation for closing the selected file is performed (step D13), the process shifts to a standby state (step A2 in FIG. 6), and the file is selected from the pull-down menu without performing the search window selection operation. Is selected (NO in step D3), the process proceeds to an open process for opening the selected file (step D12).

FIG. 10 is a flowchart for explaining the e-mail process (step A13 in FIG. 6) in detail.
First, the control unit 1 displays a folder / mail list in response to an e-mail selection operation (step E1). FIG. 13 is a view showing a display example for explaining a process until a desired mail is selected from received e-mails. (1) shows a display screen when an inbox is selected. ing. This inbox is stored and managed in a hierarchical structure as shown in FIG. 14, and the main screen MD has, for example, “main folder”, “family”, “friend” as the names of the folders in the highest hierarchy. ", ... are displayed in a list.

When an operation for selecting a desired folder / mail from the main screen MD is performed (YES in step E2), it is checked whether a folder is selected (step E3). Now, when a folder is selected, since there is a lower hierarchy in the folder, the process moves to step E4, and a keyword (search string) for searching for each mail belonging to the lower hierarchy of the selected folder is entered. Extraction is performed according to a predetermined condition (see FIG. 4) (step E4). In this case, the character string included in the body text of the lower-level mail and the character string included in the header portion are to be extracted. At that time, after performing morphological analysis on the character string to be extracted and dividing it into elements, a character string satisfying the keyword extraction condition is extracted as a keyword.

Then, the appearance frequency of the extracted keyword is obtained, the priority order of each keyword is determined according to the appearance frequency (step E5), and a keyword list according to the order of the priority order is generated (step E6). If the highest priority display flag is “1” (YES in step E7), the highest priority keyword is fixedly displayed in the search window SW (step E8), but if it is “0” (NO in step E7). ), The respective keywords are scroll-displayed in the search window SW according to the order of arrangement according to the priority order (step E9). In the case of FIG. 13A, “Tomorrow”, “schedule”, “free time”... Are scrolled and displayed in the search window SW in the order.

Further, as other operations, it is checked whether a selection operation for selecting the search window SW and making it active is performed (step E10), or whether an e-mail end operation is performed (step E14). . Now, when the closing operation for closing the mail is performed (YES in step E14), the process shifts to a standby state (step A2 in FIG. 6), but when the search window selecting operation is performed (YES in step E10), FIG. (Step E11). As a result, a list of keywords is displayed as a pull-down menu PM as shown in FIG. 13B (step C1 in FIG. 8). When a keyword is selected from the pull-down menu PM (step C2), search processing is executed accordingly (steps C3 and C4), and as shown in FIG. The search result is displayed on the matching separate screen WD (step C5). In the search result, only “Tomorrow” in the lower hierarchy of the currently selected “friend” folder is extracted, and “Tomorrow” information in the lower hierarchy of other folders that the user does not want is excluded. Can be narrowed down to the target data.

When an arbitrary file is selected from the search result (step C6), the search operation process proceeds to step E12 in FIG. 10, and an open process for opening a mail is performed. Then, when an operation for closing the mail is performed (step E13), a transition is made to a standby state (step A2 in FIG. 6). Even when the search window selection operation is not performed and mail is selected from the pull-down menu (NO in step E3), an open process for opening the mail is performed (step E12).

As described above, in this embodiment, the control unit 1 extracts a keyword for searching for data belonging to a lower hierarchy of data selected from a plurality of data stored and managed in a hierarchical structure. Since the keyword selected from the list is input to the search function, it is possible to easily search for the target data without tracing the hierarchical structure to the target data, and an appropriate keyword cannot be imagined. In both cases, it is possible to easily search for the target data without performing the operation of directly entering the keyword, and it is possible to perform a reliable search by reducing the burden on the user. It becomes. Note that data belonging to the lower hierarchy of the selected data is searched, and data belonging to the lower hierarchy of the non-selected data is not searched, so that the target data can be easily searched and unnecessary for the user. Will not give you any information.

In addition, when a keyword extracted from data belonging to a lower hierarchy of the selected data is displayed, the keyword selected from the keywords is input as a keyword for the search function. It is only necessary to select a keyword, and the burden on the user can be greatly reduced.

Since keywords are extracted from the character strings included in the names of data belonging to lower layers, for example, keywords can be easily extracted from folder names, file names, etc. A keyword can be appropriately extracted from the aggregated name, and a search can be performed using an appropriate keyword even if the name of the data does not come to mind.

Since keywords are extracted from the character strings included in the contents of the data belonging to the lower hierarchy, for example, various keywords can be extracted from the mail body, text in the file, etc. You can also search for missing keywords from the data contents.

Since the keyword is extracted from the character string of the additional data added to the data belonging to the lower hierarchy, for example, various keywords can be extracted from the additional data of the image file. Further, since various information other than the lower layer is not extracted, it is easy to narrow down to target data.

Since the keyword extracted in association with the selected data is stored in the keyword table KT, it is not necessary to perform the extraction for each data selection, so that the keyword can be displayed immediately.

Since a keyword is extracted every time data is selected, even when new data is added or changed, it can be dealt with.

Since the character string included in the data belonging to the lower hierarchy is analyzed and the keyword is extracted according to the predetermined condition, the keyword is extracted appropriately.

When a keyword is input to the search function, the keyword is input to the search window SW. Therefore, from the keyword input to the start of search can be efficiently performed without placing a burden on the user.

Since each extracted keyword is displayed in a list, the user only has to select a desired keyword from the list display.

Since each extracted keyword is displayed in a list so as to be arranged in accordance with the priority order, a desired keyword can be selected in accordance with the arrangement order of each keyword, and the keyword can be easily selected. Is possible.

Since the priority order of each keyword is determined according to the number of selections of data belonging to the lower hierarchy, it is possible to preferentially display keywords that are likely to be selected when the list is displayed.

Since the priority order of the keywords is determined according to the appearance frequency of the character strings included in the data belonging to the lower hierarchy, it is possible to preferentially display the keywords that are likely to be selected when displaying the list. .

In the above-described embodiment, the extracted keywords are displayed as a list as a pull-down menu PM in the arrangement order according to the priority order. However, in addition to the arrangement order according to the priority order, the extracted keywords are in accordance with the priority order. Each keyword may be displayed as a list in the main screen MD so as to have a form. For example, FIG. 3D shows a list of the extracted keywords in the main screen MD in the order of arrangement according to the priority (order of appearance), and the frequency according to the priority (data selection frequency). A higher keyword may be displayed in a larger character font. This makes it easy to select keywords with high priority such as the highest priority.

Similarly, as shown in FIGS. 11 (4) and 13 (4), the extracted keywords are displayed in a list in the main screen MD in the arrangement order corresponding to the priority order (time stamp order), and the priority is given. Depending on the rank (data selection frequency), a keyword with higher frequency may be displayed in a larger character font. This makes it easy to select keywords with high priority such as the highest priority.

In the above-described embodiment, the pull-down menu PM is displayed from the search window SW, but may be displayed in another window.
