Abstract

<P>PROBLEM TO BE SOLVED: To enable efficient character input corresponding to various circumstances. <P>SOLUTION: When a user inputs a character string, a communication terminal displays an input character string in an input character string display area A1, and displays a conversion character string corresponding to the character string as a conversion candidate in a conversion candidate display area A2. Also, attributes related with a position are assigned to the conversion character string. For example, such attributes as "city section" are assigned to "conference", and such attributes as "seashore section" are assigned to "seashore". In displaying the conversion candidate, the communication terminal acquires the position information indicating the position of its own equipment, and specifies the attributes of the position of its own equipment based on the position information. Then, when the conversion character string having the attributes matched with the attributes of the position of its own equipment exists, the communication terminal displays the character string at the higher rank than that of the other character strings. For example, when a user is performing character input near the sea, such a character string as "seashore" or "sea bathing" is displayed at the high rank as shown in a figure. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a technique for converting and displaying inputted characters.

A technique for displaying / determining a desired character string with a small number of operations is known for the purpose of improving the operability of character input in a mobile communication terminal. For example, by using so-called speculative conversion, the user can select a large number of conversion candidates by inputting several characters. Further, according to the technique described in Patent Literature 1, the display order of candidates in the speculative conversion can be changed according to the transmission destination of the electronic message. As a result, for example, conversion candidates are displayed in different orders when sending a private electronic message to a friend and when sending a business electronic message to a colleague at work. Character input can be performed.

That is, in the figure, the exchange ID “a” corresponds to the subscriber exchange 92a, and the exchange ID “b” corresponds to the subscriber exchange 92b. Referring to FIG. 2, since the subscriber exchange 92a is configured to communicate with the base stations 91a and 91b, the location information represented by the exchange ID “a” is the base stations 91a and 91b. It represents an area obtained by adding together the wireless communication areas. In addition, although subscriber information other than subscriber identification information is also stored in the location information database DB1, its description is omitted.

  Next, the configuration of the mobile communication terminal 10 will be described with reference to the block diagram of FIG. As shown in the figure, the mobile communication terminal 10 includes a control unit 11, a wireless communication unit 16, an operation unit 17, a display unit 18, and a GPS (Global Positioning System) receiving unit 19. The control unit 11 includes a central processing unit (CPU) 12, a read only memory (ROM) 13, a random access memory (RAM) 14, and an electronically erasable and programmable ROM (EEPROM) 15. The CPU 12 uses the RAM 14 as a work area. A program stored in the ROM 13 or the EEPROM 15 is executed, and thereby the operation of each part of the mobile communication terminal 10 is controlled.

The GPS receiver 19 includes an antenna 191 and receives radio waves transmitted from a NAVSTAR (NAVigation Satellite Timing And Ranging) satellite (so-called GPS satellite).

  The ROM 13 stores some programs in advance. Hereinafter, this is referred to as a “preinstalled program”. Specifically, the preinstalled programs are programs of a multitask operating system (hereinafter referred to as “multitask OS”), a Java (registered trademark) platform, and a native application. To outline these programs, first, the multitasking OS is an operating system that supports various functions such as allocation of virtual memory space necessary to realize pseudo-parallel execution of multiple tasks by TSS (Time-Sharing System). System. The Java platform is a program group described in accordance with a CDC (Connected Device Configuration) that is a configuration for realizing a Java execution environment 114 described later in a portable device equipped with a multitask OS.

A Java application includes a JAR (Java Archive) file obtained by combining an entity program that describes a processing procedure itself in a Java execution environment and an image file and an audio file that are used when the entity program is executed, and the JAR file. And ADF (Application Descriptor File) in which various attributes are described. This Java application is created by a content provider or a communication carrier, stored in a server device of the external network 2, etc., and downloaded appropriately from those server devices in response to a request from the mobile communication terminal 10. .

  FIG. 5 is a diagram showing a logical configuration of each unit realized in the control unit 11 of the mobile communication terminal 10 by executing various programs stored in the ROM 13 and the EEPROM 15. As shown in the figure, in the mobile communication terminal 10 that executes various programs, a positioning application 112, a mailer 113, and a Java execution environment 114 are realized on the OS 111, and the EEPROM 15 includes a first storage 115 and a second storage. 116 is secured. The positioning application 112 and the mailer 113 are realized by native applications in the ROM 13. The positioning application 112 realizes a function of specifying the position of the own device based on the radio wave received by the GPS receiver 19, and the mailer 113 realizes a function such as transmission / reception of an e-mail. Details of functions realized by the positioning application 112 and the mailer 113 will be described later.

  The Java execution environment 114 is realized by the Java platform in the ROM 13. The Java execution environment 114 includes a class library 117, a JVM (Java Virtual Machine) 118, and a JAM (Java Application Manager) 119. The class library 117 is a group of program modules (classes) having specific functions combined into one file. The JVM 118 is a Java execution environment optimized for the above-described CDC, and has a function of interpreting and executing bytecode provided as a Java application. The JAM 119 has a function of managing download, installation, activation / termination, and the like of Java applications.

  The first storage 115 is an area for storing Java applications (Jar files and ADFs) downloaded under the management of the JAM 119. The second storage 116 is an area for storing data generated when the Java application is executed after the end thereof, and a separate storage area is assigned to each installed Java application. . The data in the storage area allocated to a certain Java application can be rewritten only while the Java application is being executed, and another Java application cannot be rewritten.

  Here, functions realized by the positioning application 112 and the mailer 113 will be described. The positioning application 112 has a function of calculating information representing the position of the mobile communication terminal 10 based on radio waves received from a plurality of NAVSTAR satellites. The information calculated at this time is hereinafter referred to as “GPS position information”. In the present embodiment, it is assumed that the GPS position information is information represented by latitude and longitude. The radio wave transmitted by the NAVSTAR satellite includes a signal indicating time and a signal indicating the position of the own satellite. The mobile communication terminal 10 receives the radio wave from a plurality of NAVSTAR satellites, The position can be specified. In addition, since the method of specifying the position of the own machine based on the radio wave received from the NAVSTAR satellite is well known, the description thereof is omitted here.

  Next, FIG. 6 is a functional block diagram showing functions realized by the mailer 113. As shown in the figure, the functions realized by the mailer 113 are roughly divided into a character input function 113a, a data transmission function 113b, and a data reception function 113c. The character input function 113a is a function for determining a character string described as an e-mail destination, subject, and mail text. More specifically, the character input function 113a displays a character input by the user as a character string and a converted character string (hereinafter referred to as “converted character string”) corresponding to the character string. It is divided into a function and a function for allowing the user to select any one of the converted character strings and confirming it as character data. The data transmission function 113b is a function for generating e-mail data in a predetermined format based on the character data determined by the character input function 113a, and transmitting it to the mobile packet communication network 90. The data receiving function 113c is a function for receiving e-mail data from the mobile packet communication network 90 and displaying character data included therein. The data transmission function 113b and the data reception function 113c are the same as the well-known e-mail transmission / reception function, and thus detailed description thereof is omitted.

  The character input function 113a is realized by referring to the dictionary table TB1, the position attribute table TB2, and the character string attribute table TB3. These tables are stored in the ROM 13 or the EEPROM 15, and the contents thereof are as follows, for example.

  FIG. 7 is a diagram showing the contents of the dictionary table TB1. The dictionary table TB1 is a table that stores the converted characters and their readings in association with each other. As shown in the figure, the dictionary table TB1 is a record (row) composed of two columns of “character string” and “reading”. Is a collection of In the “character string” field, a value (data) indicating a character string such as an idiom or fixed phrase composed by combining one or a plurality of characters is stored. In addition, a value indicating the reading corresponding to the character string represented by the record is stored in the “reading” field. In the figure, all the fields are represented by characters having ideograms, but the actually stored values are values represented by predetermined code information such as character codes.

  It should be noted that at least a part of the display mode is different between the character represented by the “character string” field and the character represented by the “reading” field. Further, the value of “Reading” does not necessarily match the actual reading of the character represented by the “character string” field. For example, a “character string” field having a value of “Good morning” may be associated with “Good morning” “Good morning”. Further, the character string here may be a so-called pictogram (image assigned to a predetermined character code) or emoticon (a character or symbol string imitating a human face).

  FIG. 8 shows the contents of the position attribute table TB2. The position attribute table TB2 is a table that stores a position and an attribute related to the position in association with each other, and as shown in FIG. 6, a collection of records composed of two columns of fields “position information” and “attribute” It is. In the “position information” field, a value indicating a predetermined position by a range (area) is stored. In the “attribute” field, a value representing an attribute corresponding to the area represented by the position information is stored. In the present embodiment, it is assumed that the value of “position information” is expressed using latitude and longitude. In the present embodiment, there are three types of “attribute” values, each representing “city (1)”, “coast (2)”, or “mountain (3)”.

  Here, the meaning represented by the record of the position attribute table TB2 will be described using a specific example. For example, in the record in the first row of the position attribute table TB2 shown in FIG. 8, the value of “position information” is “N35 ° 40 ′, E139 ° 44 ′”, and the value of “attribute” is “1”. is there. That is, this record has a quadrilateral shape whose latitude is 35 degrees 40 minutes 0 seconds north to 35 degrees 40 minutes 59 seconds north latitude and longitude is 139 degrees 44 minutes 0 seconds east longitude 139 degrees 44 minutes 59 seconds east. It represents that the attribute “urban area” is associated with the area. This means that this area is an urban area.

  FIG. 9 is a diagram showing the contents of the character string attribute table TB3. The character string attribute table TB3 is a table that stores a character string and an attribute relating to a location assigned to the character string in association with each other. As shown in FIG. A collection of records composed of fields. In the “character string” field, the same value as the “character string” field of the dictionary table TB1 is stored. The character string attribute table TB3 stores a part or all of the character strings stored in the dictionary table TB1. The “attribute” field stores the same value as the “attribute” field of the position attribute table TB2. That is, in this embodiment, there are three types of “attribute” values: “1 (urban area)”, “2 (coast area)”, and “3 (mountain area)”.

  Here, the meaning represented by the record of the character string attribute table TB3 will be described with a specific example. For example, in the record in the first row of the character string attribute table TB3 shown in FIG. 9, the value of “character string” is “conference (kaigi)” and the value of “attribute” is “1”. That is, this record represents that the character string “meeting” is associated with the attribute “city”. This means that this string is related to the city, that is, the place of work or life. In the record in the third row of the character string attribute table TB3 shown in FIG. 9, the value of “character string” is “coast” and the value of “attribute” is “2”. In other words, this record represents that the character string “coast” is associated with the attribute “coast”. This means that this string relates to the coast, that is, the sea and its surroundings.

  Next, the configuration of the operation unit 17 will be described focusing on what is used especially when sending an e-mail. FIG. 10 is a diagram illustrating an external configuration of the operation unit 17. As shown in the figure, the operation unit 17 includes a mail button Bm, dial buttons B1 to B0, an upper selection button Bu, a lower selection button Bd, a confirmation button Bf, and a transmission button Bs. The functions assigned to each button will be described below.

  The mail button Bm is a button that is pressed when the user creates an e-mail. When the mail button Bm is pressed, the control unit 11 activates the mailer 113. The dial buttons B1 to B0 are buttons that are pressed when the user inputs characters. The dial buttons B1 to B0 correspond to line A, line A, line A, line A, line A, line A, line A, line A, line R, or line (Wa, A, N), respectively. . When the dial buttons B1 to B0 are pressed, the control unit 11 causes the display unit 18 to display characters corresponding to the buttons and the number of times the buttons are pressed. For example, “A” is displayed on the display unit 18 when the dial button B1 is pressed once, and “KU” is displayed on the display unit 18 when the dial button B2 is pressed three times. The upper selection button Bu and the lower selection button Bd are buttons that are pressed when the user moves the selection target. When the upper selection button Bu is pressed, the control unit 11 controls the display to move the selection target upward, and when the lower selection button Bd is pressed, the control unit 11 moves the selection target downward. Control the display so that The confirmation button Bf is a button that is pressed when the user confirms the selection target. When the confirmation button Bf is pressed, the control unit 11 specifies the content of the subsequent processing according to the selection target at that time. The send button Bs is a button that is pressed when the user confirms the content of the e-mail and sends it. When the send button Bs is pressed, the control unit 11 generates and transmits e-mail data based on the contents input by the user.

  The configuration of the mobile communication system 1 is as described above. Next, the operation when the mobile communication terminal 10 transmits an e-mail using the mobile communication system 1 will be described focusing on the characteristic features of the present invention. That is, in the following description, the main part is the part related to the character input function 113a and the data transmission function 113b described above. Note that in the following description, description of general processing when sending an e-mail is omitted as appropriate.

  First, before starting the mailer 113, the mobile communication terminal 10 calculates GPS location information and performs processing for storing it. This process is realized when the control unit 11 of the mobile communication terminal 10 executes the positioning application 112. The control unit 11 performs this process in a so-called background regardless of a user request. The GPS position information calculated at this time is information represented by latitude and longitude, and is stored in a predetermined storage area of the RAM 14 or the EEPROM 15 by the control unit 11. This process may be executed at predetermined time intervals, or may be executed each time the radio communication area to which the mobile communication terminal 10 belongs is switched to the radio communication area of another base station 91.

  Next, a process executed when the user presses the mail button Bm and the control unit 11 of the mobile communication terminal 10 activates the mailer 113 will be described with reference to the flowchart of FIG. When the mailer 113 is activated, first, the control unit 11 reads GPS position information representing the position of the own machine from a predetermined storage area (step Sa1). At this time, the CPU 12 of the control unit 11 acquires GPS position information from a predetermined storage area of the RAM 14 or the EEPROM 15. Subsequently, the control unit 11 specifies the attribute assigned to the position of the own device based on the read GPS position information and the position attribute table TB2 (step Sa2). The specific operation in step Sa2 is as follows.

  In step Sa2, the control unit 11 compares the value of “position information” in the position attribute table TB2 with the GPS position information, and identifies a record having a value of “position information” including the position of the own device. Then, the control unit 11 refers to the value of “attribute” of the record identified at this time, and identifies the attribute represented by this value as the attribute assigned to the position of the own device. For example, if the position attribute table TB2 has the contents shown in FIG. 8, when the acquired GPS position information is “35 degrees 40 minutes 12 seconds north latitude, 139 degrees 44 minutes 37 seconds east longitude”, the control unit 11 Specifies that the attribute assigned to the position of the aircraft is “urban area”.

  Next, the control unit 11 causes the display unit 18 to display a screen for allowing the user to select one of “Destination”, “Subject”, and “Text” (Step Sa3). The screen displayed on the display unit 18 at this time is hereinafter referred to as an “input selection screen”. FIG. 12 is a diagram illustrating an example of the input selection screen. On this screen, the items “destination”, “subject”, and “body” can be selected, and the item to be selected is highlighted (that is, outlined). The user selects an item to be input by pressing the upper selection button Bu or the lower selection button Bd shown in FIG. 10 to move the selection target and pressing the confirmation button Bf shown in FIG. 10 for a desired item. Until the user selects an item to be input, the control unit 11 receives supply of an operation signal from the operation unit 17 and presses the enter button Bf while changing the display content on the display unit 18 according to the operation signal. Wait for it.

  Returning to the description of FIG. When receiving an operation signal indicating that the confirm button Bf has been pressed, the control unit 11 determines an item selected by the user (step Sa4). The control unit 11 performs different processes depending on the determination result. However, since “subject” is selected and “text” is selected, almost the same process is performed. explain. When “destination” is selected by the user (step Sa4: NO), the control unit 11 causes the display unit 18 to display a screen for allowing the user to select a destination (that is, an e-mail address) (step Sa18). . The screen displayed at this time is, for example, a screen that displays a list of e-mail addresses stored as an address book.

  When “subject” or “text” is selected by the user (step Sa4: YES), the control unit 11 causes the display unit 18 to display a screen for inputting the “subject” or “text” (step Sa5). . The screen displayed by the display unit 18 at this time is hereinafter referred to as a “character string input screen”. FIG. 13 is a diagram illustrating an example of a character string input screen, which is a screen for inputting “text”. As shown in the figure, the character string input screen has an input character string display area A1 and a conversion candidate display area A2. The input character string display area A1 is an area for displaying an undetermined character among characters input by the user as a character string. The conversion candidate display area A2 is an area in which a plurality of conversion character strings (hereinafter referred to as “conversion candidates”) corresponding to the character strings displayed in the input character string display area A1 are displayed as a list.

  Returning to the description of FIG. When the character string input screen is displayed, the control unit 11 waits for the user to input a character string. That is, the control unit 11 determines whether or not the user has input a character (step Sa6). Specifically, the control unit 11 determines whether or not an operation signal corresponding to the dial buttons B1 to B0 is supplied. When it is determined that the user has input a character by acquiring the operation signal (step Sa6: YES), the control unit 11 displays a character string corresponding to the acquired operation signal in the input character string display area A1 (step S1). Sa7). At this time, the control unit 11 supplies display data for displaying the character string to the display unit 18.

  At this time, the control unit 11 refers to the contents of the dictionary table TB1, and determines whether or not there is a record in which the character string displayed in the input character string display area A1 matches the leading portion of the value of “Yomigana”. Judgment is made (step Sa8). Here, when there is no record that matches the condition (step Sa8: NO), the control unit 11 determines that there is no conversion candidate and does not display the conversion character string in the conversion candidate display area A2 (step Sa19).

  On the other hand, when there is a record that matches the condition (step Sa8: YES), the control unit 11 further determines whether or not there are a plurality of records that match the condition (step Sa9). If there is only one record that matches the condition (step Sa9: NO), the control unit 11 displays the value of the “character string” field of the record as a converted character string in the conversion candidate display area A2. (Step Sa20).

  When there are a plurality of records that match the conditions (step Sa9: YES), the control unit 11 performs processing for determining in what order the conversion candidates are displayed. Specifically, first, the control unit 11 refers to the character string attribute table TB3 to identify an attribute corresponding to the character strings (that is, converted character strings) represented by the plurality of records (step Sa10). At this time, the control unit 11 identifies a record having the same value as the “character string” value of each of the plurality of records from the character string attribute table TB3, and refers to the “attribute” value of the record. Thus, the attribute of the conversion character string is specified. Subsequently, the control unit 11 determines the display priority for the converted character string that is a conversion candidate based on the position attribute of the own device specified in step Sa2 and the attribute of each converted character string specified in step Sa10. (Step Sa11).

  Here, a method for determining the priority will be described. The control unit 11 gives a higher priority than the other converted character strings to the converted character string having an attribute that matches the attribute of the position of the own device. In addition, the priority given to the conversion character string which has an attribute different from the attribute of the position of an own machine is arbitrary, and you may use a well-known method suitably. For example, the control unit 11 may store the frequency determined as the converted character string in the past for each character string, and increase the priority as the frequency of the character string increases. Similarly, even when there are a plurality of conversion character strings having an attribute that matches the attribute of the position of the own device, the priority of conversion character strings that have been determined more in the past may be made higher.

  When the priority of the converted character string is determined in this way, the control unit 11 displays the converted character string in the conversion candidate display area A2 in the order based on the determined priority (step Sa12). At this time, the control unit 11 displays the converted character string so that a higher priority can be selected with fewer operations.

  After displaying the converted character string, that is, after the display in step Sa12 or Sa20, the control unit 11 determines whether any converted character string is selected by the user (step Sa13). Specifically, the control unit 11 determines whether or not a control signal corresponding to the confirmation button Bf is supplied. Then, when any conversion character string is selected by the user (step Sa13: YES), the control unit 11 determines the selected conversion character string as a part of the character data.

  When the conversion character string selected by the user is confirmed (step Sa13) or when a screen for selecting a destination is displayed (step Sa20), the control unit 11 selects the item (destination, subject or It is determined whether or not the content of (text) has been confirmed (step Sa14). When it is determined that the content of the item input by the user has been confirmed (step Sa14: YES), the control unit 11 determines whether all the content of the input item has been confirmed (step Sa15). These determinations are made based on, for example, whether or not the user has pressed the confirmation button Bf.

  In addition, when the conversion character string is not selected (step Sa13: NO) or when the content of the item input by the user is unconfirmed (step Sa14: NO), the control unit 11 causes the user to input the character string again. (Step Sa6), and the processing after this step is repeated. When all the contents of the input items are not confirmed (step Sa15: NO), the control unit 11 displays the input selection screen again (step Sa3), and repeats the processes after this step.

  When it is determined that all the contents of the input items have been confirmed (step Sa15: YES), the control unit 11 determines whether or not the user has instructed transmission of an e-mail (step Sa16). Specifically, the control unit 11 determines whether or not a control signal corresponding to the transmission button Bs is supplied. And when transmission of an e-mail is instruct | indicated (step Sa16: YES), the control part 11 produces | generates e-mail data based on the content which the user input, and transmits this (step S17).

  The process until the mobile communication terminal 10 transmits an e-mail is as described above. Subsequently, a screen displayed by the display unit 18 by executing the above-described process will be described with a specific example. Here, a case where the user inputs a character string “Kai” will be described as an example. In the following description, as the dictionary table TB1, the position attribute table TB2, and the character string attribute table TB3, those shown in FIGS. 7 to 9 are used, respectively.

  First, the case where the acquired GPS position information is “north latitude 35 degrees 40 minutes 12 seconds, east longitude 139 degrees 44 minutes 37 seconds” will be described. According to the position attribute table TB2 of FIG. 8, since the attribute assigned to the GPS position information is “city”, the control unit 11 preferentially displays the converted character string associated with this attribute. . According to the dictionary table TB1 shown in FIG. 7 and the character string attribute table TB3 shown in FIG. 9, the character string associated with the attribute “city” is “conference (kai)”. ”) And“ company ”. Therefore, the control part 11 displays these character strings preferentially over other character strings. Specifically, for example, when a conversion candidate is displayed in the conversion candidate display area A2, when the highest conversion candidate is first selected (inverted display), the control unit 11 As shown in FIG. 14, a character string such as “meeting” or “company” associated with the attribute “urban area” is displayed higher than other character strings.

  On the other hand, if the acquired GPS position information is “35 degrees 37 minutes 43 seconds north latitude, 139 degrees 47 minutes 4 seconds east longitude”, the attribute assigned to this GPS position information is “shore”. Therefore, as illustrated in FIG. 15, the control unit 11 displays a character string such as “coast” and “sea bathing” associated with the attribute “coast” in a higher rank than other character strings. By displaying the conversion candidates in this way, the user can select and confirm a conversion character string having a higher relevance with the position of the mobile communication terminal 10 possessed (that is, the own position) with fewer operations. Is possible.

[Second Embodiment]
Subsequently, a second embodiment of the present invention will be described. The first embodiment described above is characterized in that the display order of conversion candidates is changed according to the position of the own device, whereas the present embodiment is a communication terminal that is a destination of an e-mail. The display order of conversion candidates is varied depending on the position. Below, it demonstrates centering on the part which concerns on the characteristic of this embodiment.

  The overall configuration of this embodiment is the same as that of the mobile communication system 1 shown in FIG. However, the data stored in the mobile communication terminal is different from the first embodiment described above. Therefore, in the present embodiment, the mobile communication terminals are denoted by “mobile communication terminal 20a” and “mobile communication terminal 20b”, and are distinguished from the mobile communication terminals 10 (10a and 10b) of the first embodiment described above. If there is no need to distinguish between the mobile communication terminals 20a and 20b, they are collectively referred to as “mobile communication terminal 20”. The configuration of the mobile packet communication network 90 is the same as that of the first embodiment and is as shown in FIG.

  In this embodiment, the mobile communication terminal 20 specifies the position of the communication terminal that is the destination of the e-mail using the location information used in the location registration. Therefore, the mobile communication terminal 20 is different from the first embodiment described above in the method of associating the position and the attribute related to the position.

  The mobile communication terminal 20 of the present embodiment stores a location attribute table TB2a shown in FIG. 16 instead of the location attribute table TB2 shown in FIG. As shown in the figure, the position attribute table TB2a is a collection of records composed of two columns of fields “position information” and “attribute”. In the “location information” field, a value corresponding to the exchange ID of the subscriber exchange 92 is stored. In the “attribute” field, a value representing an attribute corresponding to the position (area) represented by the position information is stored. That is, the position attribute table TB2a is different from the position attribute table TB2 in that the object represented by the “position information” is the exchange ID. The “attribute” values in the position attribute table TB2a are the same three types as in the position attribute table TB2.

  Here, the meaning represented by the record of the position attribute table TB2a will be described using a specific example. As described above, the value stored in the “location information” field is a value corresponding to the exchange ID. This exchange ID represents the wireless communication area of the base station 91 belonging to the corresponding subscriber exchange 92. For example, in the first row record of the position attribute table TB2a shown in FIG. 16, the value of “position information” is “a” and the value of “attribute” is “1”. Therefore, this record means that the attribute “urban area” is associated with the wireless communication area formed by the base stations 91a and 91b. Similarly, the record in the second row of the position attribute table TB2a means that the attribute “coast” is associated with the wireless communication area formed by the base stations 91c and 91d, and the record in the third row is This means that the attribute “mountain part” is associated with the wireless communication area formed by the base stations 91e and 91f.

  The configuration of the mobile communication terminal 20 is as described above. Next, processing executed when the control unit 11 of the mobile communication terminal 20 activates the mailer 113 will be described with reference to the flowchart of FIG. In the figure, the same reference numerals as the steps shown in the flowchart of FIG. 11 are used for the steps for performing the same processes as those described with reference to the flowchart of FIG. Detailed description of these steps will be omitted. In the present embodiment, it is assumed that the destination of the e-mail is the mobile communication terminal 20 that uses the packet communication service by the mobile packet communication network 90.

  When the mailer 113 is activated, the control unit 11 first displays a screen for allowing the user to select a destination (that is, an e-mail address) on the display unit 18 (step Sb1). In the present embodiment, the destination is first selected in order to identify the destination e-mail address before inputting the character string corresponding to the subject or the text. The screen displayed at this time is, for example, a screen that displays a list of e-mail addresses stored as an address book. When the screen for selecting the destination first is displayed, the control unit 11 waits for the user to input an e-mail address. That is, the control unit 11 determines whether or not the user has input an e-mail address (step Sb2).

  When the e-mail address is input, the control unit 11 acquires the location information of the destination mobile communication terminal 20 (step Sb3). Specifically, the control unit 11 transmits the input e-mail address to the service control station 94 via the base station 91 or the like. When the service control station 94 receives this e-mail address, the service control station 94 reads the exchange ID (that is, area information) stored in association with this e-mail address (that is, subscriber identification information) from the position information database DB1. This is notified to the mobile communication terminal 20 that is the sender of the e-mail address.

  When the location information, that is, the information indicating the location where the destination mobile communication terminal 20 is located is acquired in this way, the control unit 11 specifies the location attribute of the destination mobile communication terminal 20 (step Sb4). The control unit 11 specifies an attribute associated with the acquired location information by referring to the position attribute table TB2a. For example, if the location attribute table TB2a has the contents shown in FIG. 16, when the acquired location information is “a”, the control unit 11 sets the attribute associated with the location of the own device to “city”. Part ".

  Subsequently, the control unit 11 causes the display unit 18 to display a screen for allowing the user to select either “subject” or “text” (step Sb5). The screen displayed at this time is different from the input selection screen of FIG. 12, and only the items “Subject” and “Body” can be selected. This is because the contents of the destination are already determined.

  Thereafter, the control unit 11 displays a character string and the like in the same manner as in the first embodiment described above, but the priority of display of the converted character string (step Sb6) is different from that in the first embodiment. By the way. In step Sb6, the control unit 11 determines a conversion character string that is a conversion candidate based on the attribute of the position of the destination mobile communication terminal 20 specified in step Sb4 and the attribute of each conversion character string specified in step Sa10. Determine the priority. The control unit 11 gives a higher priority than the other conversion character strings to the conversion character string having an attribute that matches the attribute of the position of the destination mobile communication terminal 20. Thereafter, the control unit 11 performs transmission of e-mail data in the same manner as in the first embodiment described above.

  The operation when such processing is executed will be described by taking as an example a case where an e-mail is transmitted from the mobile communication terminal 20a to the mobile communication terminal 20b. Here, it is assumed that the e-mail address of the mobile communication terminal 20b is “def@****.jp”, and the contents of the position information database DB1, the dictionary table TB1, the character string attribute table TB3, and the position attribute table TB2a are as follows: Suppose that they are as shown in FIGS. 3, 7, 9, and 16, respectively. For example, if the user inputs the mobile communication terminal 20b as the destination and then inputs the character string “Kai”, the control unit 11 of the mobile communication terminal 20a sets the exchange ID “b” as the location information. Therefore, based on the contents of the position attribute table TB2a, the area where the mobile communication terminal 20b is located is specified as the “coast”. Therefore, at this time, the control unit 11 displays the conversion character strings such as “coast” and “sea bathing” to which the attribute “coast portion” is assigned higher than the other conversion character strings. That is, the screen displayed at this time is as shown in FIG.

  By executing such processing, the mobile communication terminal 20 displays a converted character string having an attribute associated with the position of the destination mobile communication terminal 20 with priority over other converted character strings. Is possible. As a result, the user can select and confirm a converted character string having a higher relevance to the position of the destination mobile communication terminal 20 (that is, the position of the communication partner) with fewer operations.

[Third Embodiment]
Subsequently, a third embodiment of the present invention will be described. Whereas the first and second embodiments described above are characterized in that the display order of conversion candidates is changed according to the position of the mobile communication terminal, this embodiment transmits an e-mail. The display order of conversion candidates is varied according to time. Below, it demonstrates centering on the part which concerns on the characteristic of this embodiment.

  The overall configuration of this embodiment is the same as that of the mobile communication system 1 shown in FIG. However, the configuration of the mobile communication terminal, stored data, and the like are different from those of the first embodiment described above. Therefore, in the present embodiment, the mobile communication terminal code is “mobile communication terminal 30”, and is distinguished from the mobile communication terminal 10 of the first embodiment described above. The configuration of the mobile packet communication network 90 is the same as that of the first embodiment and is as shown in FIG.

  FIG. 18 is a block diagram showing a configuration of the mobile communication terminal 30. The mobile communication terminal 30 includes a control unit 11, a wireless communication unit 16, an operation unit 17, a display unit 18, a GPS reception unit 19, and a timer 31. In response to a request from the control unit 11, the timer 31 supplies time information indicating the time at the time of the request. The time information is information represented by hours, minutes, and seconds, for example, “01.23.45 (1:23:45)”. The configurations of the control unit 11, the wireless communication unit 16, the operation unit 17, the display unit 18, and the GPS reception unit 19 are the same as those of the mobile communication terminal 10.

  Further, the mobile communication terminal 30 of the present embodiment stores a time zone attribute table TB4 shown in FIG. 19 in place of the position attribute table TB2 shown in FIG. The time zone attribute table TB4 is a table that stores the time and the attribute assigned to that time in association with each other, and as shown in the figure, is composed of two columns of fields “time zone information” and “attribute”. Is a collection of records. In the “time zone information” field, a value representing a time zone obtained by dividing one day into a predetermined range is stored. In the “attribute” field, a value representing an attribute corresponding to the time zone represented by the time zone information is stored. In the present embodiment, it is assumed that the value of “time zone information” is expressed using hours, minutes, and seconds. In the present embodiment, there are three types of “attribute” values, each representing “morning (1)”, “daytime (2)”, or “night (3)”.

  Here, the meaning represented by the record of the time zone attribute table TB4 will be described using a specific example. For example, the record in the first row of the time zone attribute table TB4 shown in FIG. 19 has a “time zone information” value of “0.00.00-4.59.59” and an “attribute” value of “3”. is there. In other words, this record represents that the attribute “night” is associated with the time zone from 0: 0: 0 to 4:59:59. This means that this time zone is regarded as night. Similarly, for the records after the second line, the time from 5:00:00 to 11:59:59 is morning, the time from 12:00:00 to 17:59:59 is noon, and 18:00 It means that from 0:23 to 23:59:59 is regarded as night.

  Further, the mobile communication terminal 30 of the present embodiment stores a character string attribute table TB3a shown in FIG. 20 instead of the character string attribute table TB3 shown in FIG. The character string attribute table TB3a is a table that stores a character string and an attribute assigned to the character string in association with each other, and includes two columns of “character string” and “attribute” as shown in FIG. Is a collection of records to be processed. In the “character string” field, the same value as the “character string” field of the dictionary table TB1 is stored. The character string attribute table TB3a stores some or all of the character strings stored in the dictionary table TB1. The “attribute” field stores the same value as the “attribute” field of the time zone attribute table TB4. That is, in this embodiment, there are three types of “attribute” values: “1 (morning)”, “2 (daytime)”, and “3 (night)”. That is, in the records in the first and second lines of the character string attribute table TB3a shown in FIG. 20, the attribute “morning” is assigned to the character string “Hello!”, And “Please take a rest”. Represents that the attribute “night” is assigned.

  The configuration of the mobile communication terminal 30 is as described above. Next, processing executed when the control unit 11 of the mobile communication terminal 30 starts the mailer 113 will be described with reference to the flowchart of FIG. In the figure, the same reference numerals as the steps shown in the flowchart of FIG. 11 are used for the steps for performing the same processes as those described with reference to the flowchart of FIG. Detailed description of these steps will be omitted.

  When the mailer 113 is activated, the control unit 11 first acquires time information from the timer 31 (step Sc1). The time represented by the time information acquired at this time is hereinafter referred to as “current time”. Subsequently, the control unit 11 specifies the attribute assigned to the current time based on the acquired time information and the time zone attribute table TB4 (step Sc2). The specific operation in step Sc2 is as follows.

  In step Sc2, the control unit 11 compares the value of “time zone information” in the time zone attribute table TB4 with the time information, and identifies a record whose value of “time zone information” includes the current time. Then, the control unit 11 refers to the value of “attribute” of the record identified at this time, and identifies the attribute represented by this value as the attribute assigned to the current time. For example, if the time zone attribute table TB4 has the contents shown in FIG. 20, if the acquired time information is “9.00.00 (9:00:00)”, the control unit 11 The attribute assigned to is identified as “morning”.

  Thereafter, the control unit 11 displays a character string and the like in the same manner as in the first embodiment described above, but the priority of display of the converted character string (step Sc3) is different from that in the first embodiment. By the way. In step Sc3, the control unit 11 determines the priority for the conversion character string that is a conversion candidate based on the attribute of the current time specified in step Sc2 and the attribute of each conversion character string specified in step Sa10. The control unit 11 gives a higher priority than the other conversion character strings to the conversion character string having an attribute that matches the attribute of the position of the destination mobile communication terminal 20. Thereafter, the control unit 11 performs transmission of e-mail data in the same manner as in the first embodiment described above.

  The operation when such processing is executed will be described. Here, the contents of the position information database DB1, the dictionary table TB1, the time zone attribute table TB4, and the character string attribute table TB3a are as shown in FIGS. 3, 7, 19, and 20, respectively. . For example, if the current time is in the 10 o'clock range and the user inputs a character string “O”, the control unit 11 of the mobile communication terminal 30 calculates the current time based on the contents of the time zone attribute table TB4. Identified as “morning” time zone. Therefore, at this time, as shown in FIG. 22, the control unit 11 converts the conversion character string “Morning” to which the attribute “morning” is assigned, and “sleeping” to which the attribute “night” is assigned. Is displayed above the converted character string.

  By executing such processing, the mobile communication terminal 30 can preferentially display the converted character string having the attribute associated with the current time over other converted character strings. As a result, the user can select and confirm a converted character string having a higher relevance with the current time (that is, the time when the electronic mail is transmitted) with fewer operations.

[Fourth Embodiment]
Subsequently, a fourth embodiment of the present invention will be described. While the first and second embodiments described above are characterized in that the display order of conversion candidates is changed according to the position of the mobile communication terminal, this embodiment is close to the own device. The display order of conversion candidates is made different depending on the existing mobile communication terminal. Below, it demonstrates centering on the part which concerns on the characteristic of this embodiment.

  The overall configuration of this embodiment is the same as that of the mobile communication system 1 shown in FIG. However, the configuration of the mobile communication terminal, stored data, and the like are different from those of the first embodiment described above. Therefore, in the present embodiment, the mobile communication terminals are denoted by “mobile communication terminal 40a” and “mobile communication terminal 40b”, and are distinguished from the mobile communication terminals 10 (10a and 10b) of the first embodiment described above. If there is no need to distinguish between the mobile communication terminals 40a and 40b, these are collectively referred to as “mobile communication terminal 40”. The configuration of the mobile packet communication network 90 is the same as that of the first embodiment and is as shown in FIG.

  FIG. 23 is a block diagram showing the configuration of the mobile communication terminal 40. The mobile communication terminal 40 includes a control unit 11, a wireless communication unit 16, an operation unit 17, a display unit 18, a GPS reception unit 19, and a short-range wireless communication unit 41. The configurations of the control unit 11, the wireless communication unit 16, the operation unit 17, the display unit 18, and the GPS reception unit 19 are the same as those of the mobile communication terminal 10. The short-range wireless communication unit 41 includes an antenna 411 and performs wireless communication with the mobile communication terminal 40 existing within a predetermined range near the own device. Although the communication method of the short-range wireless communication unit 41 is arbitrary, for example, a method based on the Bluetooth (registered trademark) standard can be used. When this method is used, it is possible to perform communication between terminals within a radius of about 10 m.

  The control unit 11 is configured to be able to acquire information that can identify other mobile communication terminals 40 via the short-range wireless communication unit 41. The information acquired at this time is hereinafter referred to as “terminal identification information”. The terminal identification information may be, for example, an appropriate character string determined in advance, or may be a telephone number or an e-mail address. For convenience of explanation, in this embodiment, the terminal identification information is a code of the mobile communication terminal 40. Use the alphabet attached to the end of.

  The mobile communication terminal 40 of the present embodiment stores a character string condition table TB5 shown in FIG. 24 instead of the character string attribute table TB3 shown in FIG. The character string condition table TB5 is a table that stores a character string and a predetermined condition assigned to the character string in association with each other. As shown in FIG. A collection of records composed of fields. In the “character string” field, the same value as the “character string” field of the dictionary table TB1 is stored. The character string attribute table TB3 stores a part or all of the character strings stored in the dictionary table TB1.

  In the “condition information” field, a value representing a predetermined condition for determining display priority is stored. The predetermined conditions include terminal identification information, the number of mobile communication terminals 40 existing in the vicinity of the own device, and the like. For example, the value of “condition information” in the record in the first row of the character string condition table TB5 shown in FIG. 24 indicates that the acquired terminal identification information is “b”. This means that the “predetermined condition” described above is “the mobile communication terminal 40 whose terminal identification information is“ b ”(that is, the mobile communication terminal 40 b) exists in the vicinity of the own device”. is doing. Further, the value of “condition information” in the record in the fourth row of the character string condition table TB5 shown in FIG. 24 indicates that the total number of acquired terminal identification information is equal to or greater than a predetermined number (here, “5”). ing. This means that the “predetermined condition” described above is “there are five or more mobile communication terminals 40 in the vicinity of the own device”. In the “condition information” field, it is not necessary to store significant values in all of the fields, and it is sufficient that values are stored only in records for which conditions need to be set.

  The configuration of the mobile communication terminal 40 is as described above. Next, processing that is executed when the control unit 11 of the mobile communication terminal 40 activates the mailer 113 will be described with reference to the flowchart of FIG. In the figure, the same reference numerals as the steps shown in the flowchart of FIG. 11 are used for the steps for performing the same processes as those described with reference to the flowchart of FIG. Detailed description of these steps will be omitted.

  When the mailer 113 is activated, the control unit 11 first acquires terminal identification information via the short-range wireless communication unit 41 (step Sd1). And the control part 11 specifies the mobile communication terminal 40 and the number which exist in the vicinity of an own machine based on the acquired terminal identification information (step Sd2). Then, the control part 11 displays a character string etc. in the same way as 1st Embodiment mentioned above (step Sa3-Sa9).

  When there are a plurality of records in which the character string displayed in the input character string display area A1 matches the leading portion of the “Yomigana” value (step Sa9: YES), the control unit 11 refers to the character string condition table TB5. By doing this, the condition information corresponding to the character string (that is, the converted character string) represented by the plurality of records is specified (step Sd3). And the control part 11 determines the priority of a display about the conversion character string which is a conversion candidate based on the specified condition information (step Sd4).

  Here, a method for determining the priority will be described. The control unit 11 refers to the condition information specified in step Sd3, the mobile communication terminals 40 existing in the vicinity of the own device specified in step Sd2, and the number thereof, and there is a converted character string that satisfies the condition. Determine whether or not. And when the conversion character string which satisfy | fills conditions satisfy | fills, the control part 11 gives a priority lower than other conversion character strings with respect to the conversion character string. Thereafter, the control unit 11 performs transmission of e-mail data in the same manner as in the first embodiment described above.

  The operation when such processing is executed will be described. Here, it is assumed that the subject of operation is the mobile communication terminal 40a, and the contents of the dictionary table TB1 and the character string condition table TB5 are as shown in FIGS. 3 and 24, respectively. For example, when the mobile communication terminal 40b exists in the vicinity of the own device and the user inputs a character string “Baka”, the control unit 11 of the mobile communication terminal 40a reads the contents of the character string condition table TB5. Based on the above, the priority of the conversion character string “idiot” is made lower than the priority of other conversion character strings such as “kasuka” and “vacation”. Therefore, at this time, as shown in FIG. 26, the control unit 11 displays a conversion character string such as “Kasuga” or “Vacance” at a higher level than the conversion character string “Idiot” (Example 1).

  For example, if there are five or more mobile communication terminals 40 in the vicinity of the own device, and the user inputs the character string “Hana”, the control unit 11 of the mobile communication terminal 40a Based on the contents of the character string condition table TB5, the priority of the conversion character string “Hanako-chan” is set lower than the priority of other conversion character strings such as “flower” and “nose”. Therefore, at this time, as shown in FIG. 27, the control unit 11 displays a converted character string such as “flower” or “nose” above the converted character string “Hanako-chan” (example 2).

  By executing such processing, the mobile communication terminal 40 displays a specific conversion character string according to the presence of the mobile communication terminal 40 existing in the vicinity of the own device, that is, other users around the user. It becomes possible to make it difficult or to display easily. For example, condition information is set in advance in the same manner as in Example 1 for expressions that are inappropriate for display or input (for example, violent words or inferior words) for the mobile communication terminal 40 that the parent has for the child. This makes it difficult for the child to select the inappropriate expression described above when the parent is near the child. In this case, furthermore, by preventing the conversion character string satisfying the predetermined condition from being displayed, an inappropriate expression is not displayed on the child's mobile communication terminal 40, and the child sees the inappropriate expression. Opportunities can also be reduced.

  In addition, for example, by setting condition information in advance as in Example 2 for expressions that are not desired to be seen by others (for example, words related to personal privacy and business secrets) When other users can see the character string input screen, it is possible to make it difficult to display expressions that other people do not want to see. Thereby, it becomes possible to suppress the matter that the user wants to keep secret from being revealed to others.

[Modification]
In the above, the present invention has been described by exemplifying four types of embodiments, but the present invention is not limited to the above-described embodiments, and can be implemented in various other modes. In the present invention, for example, the following modifications can be applied to the above-described embodiment. These modifications can be combined as appropriate.

  In the first embodiment described above, the GPS position information is used as the position information of the own device. In the second embodiment described above, the location information is used as the position information of the transmission destination. The location information may be used, or the GPS location information may be used as the location information of the transmission destination. In the above-described embodiment, the location information is information representing an area obtained by adding the wireless communication areas of the plurality of base stations 91. However, the location information is the wireless communication area of the single base station 91. You may comprise by. In this way, it is possible to further improve the accuracy of the location information.

  In the second embodiment described above, the location information is acquired as the location information of the transmission destination, and the priority of display of the converted character string is determined by referring to the attribute associated therewith. Instead of the area information, the above-described attribute may be acquired as the position information. For example, the service control station may store the association between the location information and the attribute, and the service control station may transmit information representing the attribute to the mobile communication terminal.

  In the above-described third embodiment, the time information is information representing time, and the attributes of “morning”, “daytime”, and “night” are associated with this time information. It may be a shorter period or a longer period. For example, the time information may be information that also represents a date, and the attributes “spring”, “summer”, “autumn”, and “winter” may be associated with the time information. In this way, it is possible to preferentially display a converted character string that is highly relevant to the season. Also, for example, a conversion character string that is highly relevant to work is preferentially displayed during working hours, or a conversion character string that is highly relevant to entertainment is preferentially displayed on holidays. May be.

  In the above-described embodiment, an electronic mail is shown as an example of the electronic message. However, the electronic message created by the user is not limited to the electronic mail, and may be, for example, a so-called SMS (Short Message Service). . Further, embodiments that do not require the presence of a transmission destination (that is, other than the second embodiment) can be applied not only to character input in electronic messages but also to various other character inputs.

  In order to be able to use it for various character input, it is desirable that the functions necessary for the processing for determining the display priority are configured as a single program and provided in the form of a so-called library. . Further, such a program can be provided by being recorded on a recording medium such as a CD-ROM, or can be provided from a predetermined server device via the Internet or a mobile packet communication network.

  In the above-described embodiment, the information indicating the attribute such as the position and the time zone is provided separately from the dictionary table TB1, but for example, a plurality of dictionary tables are provided and the attribute is associated with each dictionary table. It may be. In short, in the present invention, it is sufficient that data (“character string” and “converted character string”) corresponding to the above-described dictionary table TB1 and information corresponding to the attribute are stored with some association, The specific storage mode is not particularly limited. Note that when the attribute is associated with each of the plurality of dictionary tables, only the dictionary table associated with the specified attribute may be used when displaying the converted character string corresponding to the input character string. Then, the control may be performed such that the conversion character string stored in the other dictionary table is used together with the conversion character string stored in the dictionary table preferentially.

  In the above-described embodiment, a mobile phone is exemplified as a mobile communication terminal for inputting characters. However, a PDA (Personal Digital Assistants) having a communication function or a notebook personal computer may be used. In addition to a mobile communication terminal, a stationary communication terminal such as a server device or a desktop personal computer may be used.

  In the above-described embodiment, as an example of displaying the conversion character string preferentially, an example in which the conversion character string is displayed higher than other conversion character strings has been described. However, the conversion character string is preferentially displayed. The display mode in the case is not limited to such an example. For example, if conversion candidates are displayed one by one, a mode in which a conversion character string with a high priority is displayed before other conversion character strings may be used. In short, any display form may be used as long as the conversion character string with higher priority can be selected and confirmed with fewer operations.

  In the above-described embodiment, the conversion candidate display operation in so-called speculative conversion has been described. However, of course, the present invention may be applied to kana-kanji conversion in which only conversion candidates that completely match the input character string are displayed. Is possible.
