BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device in a cellular radio communication system, and more particularly, to a portable terminal device capable of mounting a dictionary for language translation.

[0002]

2. Description of the Related Art GSM (Global System for Mobile comm
unications) digital cellular system (Digital
The Cellular System) is virtually a global standard and is used in various countries, and their users frequently use portable terminal devices (hereinafter simply referred to as portable terminals) outside their native language. Outside the native language, it is convenient to have a dictionary that translates between the language used in the visiting country and the native language. As a common language, English is generally widely used, but English is not always written on the display of various places visited. If you visit many countries, you will need several dictionaries for the languages you visit.

[0003] As a technique related to such a problem, Japanese Patent Application Laid-Open No. 2000-194698 discloses that an information processing apparatus detects the position of a user by using a GPS (Global Positioning System) or the like and uses the information in a local area. There is disclosed a technology for selecting a translation word dictionary of a language to be updated and downloading and updating the dictionary from a server.

In Japanese Patent Application Laid-Open No. Hei 7-30672,
A technique for downloading a necessary dictionary or program from an external database or the like in a handy personal computer device such as an electronic organizer is disclosed.

[0005]

However, every time a visit is made to a different country, the language spoken in that country is checked, a server is accessed, and a dictionary for translating between the language and the native language is created. The work of designating and downloading the dictionary data requires cumbersome work for the user. Also, downloading of dictionary data takes a predetermined time, and a situation may occur in which it is not enough to start the download operation when the dictionary is needed. In addition, GPS
In addition to the need for a GPS receiver to separately detect the position, this not only leads to an increase in cost, but also requires periodic execution separately from the standard processing of the digital cellular system.
There is a problem that the processing load on the mobile terminal increases. Further, processing for specifying the corresponding country from the detected position information (latitude and longitude) is also required.

The present invention has been made in view of the above background, and has as its object to relatively easily and automatically confirm the language of a dictionary to be downloaded and to enter a different language zone. It is an object of the present invention to provide a mobile terminal device that can automatically download appropriate dictionary data at times.

[0007]

In order to achieve the above object, a portable terminal device according to the present invention is a portable terminal device in a cellular radio communication system, and stores native language information of a user. Means, country information confirmation means for confirming country information transmitted from the base station every time the location of the mobile terminal device is updated, network connection means for connecting to a network, and country transmitted from the base station. Download means for downloading, from the server, dictionary data for performing translation between a native language determined by the native language information and a language used in the country when the information has changed, to a server on the network; And a dictionary storage unit for storing the downloaded dictionary data, and a dictionary using unit for using the dictionary data.

[0008] With this configuration, the portable terminal device can automatically determine necessary dictionary data according to the destination and automatically download the dictionary data without the user being particularly conscious.

[0009] If there are a plurality of languages used in the country and a dictionary is required for only some of the languages, the language identification information is received, and a dictionary is set between the required language and the native language. It is also possible to make it possible to download only the dictionary data for performing the translation. Thus, unnecessary download of dictionary data can be omitted.

The system further comprises means for confirming whether or not a dictionary of a language corresponding to the country information has already been stored in the dictionary storage means. If the dictionary has not been stored, the download means downloads the dictionary data from the server. If it is downloaded and stored, the download can be omitted. Thereby, it is possible to avoid downloading the same dictionary data repeatedly.

[0011] The dictionary using means may include an input means for receiving a key input or a voice input of an arbitrary word, and an output means for displaying or outputting a word converted from the dictionary data by the dictionary data.

[0012] Preferably, the portable terminal device includes, for dictionary data stored in the dictionary storage means, a country code as the country information when the dictionary data is downloaded, and identification information of a language used in the country. And a language code table storing a language code as the language code.

The native language is a subscriber identification module (SI
M) International mobile subscriber number (IMSI) stored in
It can be determined from the country information set inside.
Alternatively, the system further includes a native language selecting unit that enables the native language to be selected from a plurality of registered languages, and the control unit updates or newly updates the language code table when the native language is changed. May be created. As such a native language selecting means, for example, a language initial setting for selecting a display language can be used.

[0014] The dictionary storage means may be a memory detachable from the portable terminal device. In this case, the language code table may be stored in the detachable memory together with the dictionary data. preferable. In this case, when the removable memory attached to the portable terminal device is replaced, the control unit checks the presence or absence of the language code table in the newly attached memory. If it does not exist, a new language code table is created.

Further, according to the present invention, a computer program operating on a portable terminal device in a cellular radio communication system confirms country information transmitted from the base station every time the location of the portable terminal device is updated. Automatically accessing a server on a network when country information transmitted from the base station changes, and a language determined by native language information set in the portable terminal device. Downloading dictionary data for translation between languages used in the country from the server. This computer program may be initially installed when the portable terminal device is shipped, or may be installed afterward.

The user enters the telephone number of the other party into the portable telephone A1.
Enter 03 and make a dial call. This call can be automatically made by internal software of the mobile phone A103. The mobile phone A103 connects to the nearest mobile phone base station A101 through a wireless interface (Air Interface) A105. The mobile phone base station A101 is a digital interface (Digital Interface).
e) Mobile phone base station B at 106 (usually IDSN etc.)
The mobile phone B104 is connected to the mobile phone base station B102 via a wireless interface B107.
Has been registered in the mobile phone A1
In 03, a line is connected to the mobile phone B104, and a call can be made. Similarly, first, the portable telephone B104 performs location registration with the nearest portable telephone base station B102. At this time, LAI B112, which is information of the base station, is sent from the mobile phone base station B102 to the mobile phone B104. Further, in order to authenticate the user to the mobile phone base station B102, the IMS stored in the SIM B115 is used.

t), Broadcast SMS-CB (Short Message Service)
Cell Broadcast) or GPRS (General Packet Rad)
io Service), send certain data to the user,
In response to this, a message of the user, a selection result, and the like are sent back. Also, a web page on the Internet (Web Page) can be browsed through a dedicated gateway so that it can be displayed on the mobile terminal A103 or the mobile terminal B104. In the present embodiment, the service provider 109 further provides a dictionary data download service. Preferably, the dictionary data is accompanied by speech synthesis or speech recognition data.

Next, referring to FIG. 2, a schematic configuration of a general digital cellular portable telephone as an example of a portable terminal device according to the present invention will be described. The reception signal input from the antenna 201 is guided to the reception RF section 203 by the selector 202. Here, the band limitation and automatic gain control (Automatic Gain Control) are required so that the received signal is at an appropriate level.
And so on. Next, in order to convert a desired reception frequency to a constant frequency, the frequency controlled local oscillator 21 is controlled.
Then, the process proceeds to a mixer 204 that mixes the signal from No. 1 and the output of the reception RF unit 203. This output is input to the reception IF unit 205, A / D converted, and output at a constant bit rate (Bit Rat).
It becomes IQ digital data having e). This IQ digital data is subjected to fading (Fadi
ng), the type of received signal, de-interleave (De-Interleave), error correction (Error Correlation)
(rection), appropriate decoding is performed, and the data is separated into audio data and communication data. Since the audio data is usually compressed and sent in blocks for each received burst (Burst), the audio data is expanded and decoded (Decoded) by the audio decoding unit 207, and then the audio sampling rate (Sa
D / A conversion is performed according to the mpling rate. After this, D
The / A-converted analog signal is power-amplified by the speaker amplifier 208 and reaches the speaker 209 to be emitted.
The pronunciation reproduction of words specified in dictionaries etc. is usually performed by DSP
(Digital Signal Processor) or the like, for example, by sending voice synthesis data or sampled signal data to a voice decoding unit 207. On the other hand, the communication data is also separated by the reception demodulation unit 206 and returned to the final original data by the communication data decoding unit 210.
This data is sent to the I / O 220 via the CPU bus 225.
To the external device via the data I / F 220c.

On the other hand, on the transmitting side, the sound is
The signal can be converted to an analog audio signal through 18. Microphone 2
Since the output of 18 is small, it is amplified to a required voltage by the microphone amplifier 217. The amplified audio signal is first A / D converted and digitized by the audio encoding unit 216 at an appropriate sampling rate. When inputting a dictionary or the like by voice, the voice coding unit 216 usually composed of a DSP
And a speech recognition processing program. During a call, the voice signal is encoded and compressed, and collected into blocks that match burst signals in RF. On the other hand, the digital data input from the data I / F 220c of the I / O 220 is compiled into an appropriate block by the communication data encoding unit 219. Data from the voice encoding unit 216 and the data from the communication data encoding unit 219 are collected by the transmission modulation unit 215, and are converted into IQ digital data having a constant data rate. This signal is D / A-converted by the transmission IF unit 214 and converted into an analog modulation signal, and then mixed with a signal for conversion from the local oscillator 211 by the mixer 213 in order to convert the signal to a desired transmission frequency. The signal converted to the desired frequency is power-amplified by the transmission RF unit 212 in order to obtain necessary transmission power, and is radiated from the antenna 201 via the selector 202.

The ROM 221 which is a read-only memory has:
A program executed by the central processing unit CPU 224 and data such as fonts for display are stored. The RAM 222, which is a write / read memory at any time, has a central processing unit C
It is used when the PU 224 stores data during calculation as needed during execution of the program, or temporarily stores data when moving data from the receiving unit or the transmitting unit or vice versa. The EEPROM 223, which is an electrically erasable non-volatile memory, has a power supply of a cellular phone which is OF
Even if F is set, for example, the immediately preceding setting conditions are stored,
In the case of using the same setting when the power is turned on next time, storing these setting parameters provides convenience to the user. A real-time clock (RTC) 226 for timekeeping is a part that provides date and time data, and is used for, for example, a time stamp of data, a clock display of a mobile phone, an alarm, and the like. . The input / output unit I / O 220, which is an interface with an external device, includes a display I / F 220a, a keyboard / jog dial (Jog dial).
Dial) I / F 220b, data I / F 220c, and the like. By the way, the movable direction of the five-dimensional (5D) jog dial is forward rotation, reverse rotation, dial push,
There are five directions of front push and back push.
The external storage I / F 220d is used when the main unit uses data from a removable nonvolatile memory such as a memory stick (trademark of Sony Corporation).
In the case of downloading a large amount of data such as a dictionary from the service provider 109 shown in (1), when the RAM 222 of the random access memory of the main unit cannot sufficiently cope with it, the I / F used for storing the data is used. is there. The SIM I / F 220e controls an interface with the SIM.

The example of the dictionary selection screen of the screen 300 shown in FIG. 3 displays a state after the dictionary data is automatically downloaded when the user goes to a certain area and the portable terminal performs location registration. . Here, a case where the user goes to Switzerland is shown as an example. The location of the user can be known from the LAI A111 sent from the mobile base station A101 in the system shown in FIG. Therefore, the country name or place name “Switzerland” in the text 301 on the screen 300 can be inserted into other fixed phrases and displayed. Since the languages used in Switzerland are French, German and Italian, they are displayed as candidates for the dictionary language. Here, the user's native language is Japanese. If the user is in Switzerland, by providing information on the user's native language (identification information for specifying the country or language) stored in the mobile terminal to a server such as an operator (carrier) or a service provider The mobile terminal can automatically download the dictionary between the native language and these three languages. Screen 300
The first option 302 displays a check box for selecting the use of dictionaries of all languages used in the visited place. In order to save the user's operation, this check box can be automatically selected as a default. The second option 303 displays a check box for using French, and the third option 304
Displays a checkbox for using German, and similarly, a fourth option 305 displays a checkbox for using Italian. In the example of FIG. 3, it is assumed that the user has selected French, which is the second option 303, and German, which is the third option 303, by using an arbitrary operation means such as a jog dial, and the check boxes thereof are displayed in black. I have.

An example of a dictionary voice input screen of the screen 400 shown in FIG. 4 shows a setting screen in a case where a user inputs voice and uses a dictionary. A text 401 indicates an operation method for the user. The user can set the voice input according to the instruction of the text. The first option 402 has its check box turned black, indicating that the native language has been selected as the language for voice input. Similarly, the second option 403 indicates that French is selectable but not selected as the conversion output by a white check box.
A third option 404 indicates that German is selected as the conversion output by the check box being hatched. Although the fourth option 405 includes an Italian dictionary, the use of the fourth option 305 in the example of the dictionary selection screen shown in FIG. This indicates that use has been suspended as not being selected.

The automatic download display example of the screen 600 shown in FIG. 5 shows a case where a new English dictionary is downloaded when the user first moves to Switzerland and then moves to the UK. In this example, when a mobile device first registers in the UK, it checks for a dictionary in the language corresponding to the country code of the destination (ie, an English dictionary)
It is assumed that it is determined that the dictionary data does not exist in the portable terminal (an internal memory or an external storage device such as a mounted memory stick). Text 5
01 "UK" can be determined by location registration, and as described above, since the dictionary does not exist, the word "new dictionary was automatically imported and switched" is automatically added. Also, the dictionary that was downloaded when he was in Switzerland previously remains without being deleted because there is still room in the memory.
0 has been added to the available dictionary list. A first option 502 displays a check box for selecting to use all dictionaries. The second option 503 includes a check box for selecting the use of English, in this example, moving from Switzerland to the UK and automatically switching the dictionary, so that the check box is blackened and English is selected. It indicates that. The third option 504 is French, obtained in the place where it was before, the fourth option 5
05 is the German available at the previous location, the fifth option 506 is the Italian available at the previous location, the respective dictionaries are still stored in the mobile terminal and are available Check boxes are displayed.

An example of a sound output operation screen shown on a screen 600 in FIG. 6 is an example of a screen for confirming the pronunciation of a word input using a keyboard or a jog dial or the like. Here, it is assumed that the German dictionary has been selected in advance. The text 601 indicates a dictionary selected as an output language and an instruction for a pronunciation operation. Input word 60
Numeral 2 is a word input using a keyboard or a jog dial. When the word input is completed, the voice output can be heard each time the jog dial is pressed.

The LAI specification shown in FIG. 7 is, for example, the LAI A transmitted by the base station A 101 in the system shown in FIG.
111 is received by the mobile phone A103 and SIM A11 is received.
3 shows a part of the format when stored in the LAI file (for details, see European Telecommu
nication Standard Institute (ETSI) GSM 11.11). The LAI 700 includes a mobile country code “MCC” (Mobile Country Code) as country information for specifying a country (or area) to which the base station belongs, and a mobile network code “MNC” (Mobile Network Code) for specifying a network to which the base station belongs. ).
The lower 4 bits (Bit) of the first byte (Byte) 701 indicate the most significant digit of the MCC, and the upper 4 bits indicate the second digit. The lower 4 bits of the second byte 702 indicate the third digit. The upper 4 bits of the second byte 702 indicate a data break. The third byte 703 indicates the MNC and is a two-digit number in the same order as the MCC. This MNC is not directly related to the present invention.
This MCC allows the user to determine which country
(Country or region).

FIG. 8 shows an example of the IMSI specification. In the system shown in FIG. 1, for example, the mobile phone A103
The IMSI A114 stores an IMSI A114, and FIG. 8 shows a format of the IMSI 800 (for details, see the above-mentioned ETSI GSM 11.11). The first byte 801 is the length of IMSI (Length of IMSI).
The number indicating I) is coded, in this case "
9 ". The lower 4 bits of the second byte 802 are used for data check, etc., and" P "indicates parity. It is not particularly relevant to the present invention. The upper 4 bits of the second byte 802 are the MCC. It shows the most significant digit (Digit 1) The lower 4 bits of the third byte 803 represent the second digit of the MCC (Digit 2) The upper 4 bits are the three digits of the MCC The least significant digit (Digit 3) is shown.
The lower 4 bits of the fourth byte 804 represent the first digit of the MNC, and the upper 4 bits represent the second digit (lower digit). The fifth to ninth bytes 805 indicate a subscriber unique number issued to a user at the time of subscription.

FIG. 9 shows the language initialization (Language Preferenc).
e) An example of the table 900 is shown. This corresponds to, for example, the SIM A of the mobile phone A103 in the system of FIG.
The language initialization table 900 shown in FIG. 9 shows the format (for details, see ETSI
GSM 11.11). The language selected in the table 900 is used for display on the portable terminal. The first byte 901 indicates the language with the highest priority. Normally, this byte is mandatory information and the other bytes are optional. The second byte 902 indicates the language of the second priority, and the third byte 903 indicates the language of the third priority. Since the number of bytes n up to the byte n904 is determined in consideration of the amount of other information used inside the SIM,
The number of languages that can be registered in this file differs depending on the operator who issues the SIM. The user checks the language list from the display on the mobile terminal, and selects a language to be used for display or the like, and the language is recorded in the SIM. The user can change the priority of the language once set. The user can also use the language code with the highest priority stored in the language initial setting table 900 as the native language information.

FIG. 10 shows a language code table (Language
Code Table) 1000 is shown. This table shows the correspondence between the MCC and the language used in the country (or region) indicated by the MCC. For the dictionary stored in the mobile terminal, the country code of the country where the download was performed and the correspondence Are stored in the terminal as a set. When dictionary data is stored in a removable memory, the language code table 1000 is also preferably created in the same memory. This table 100
By referring to 0, the country where the dictionary data stored in the portable terminal was downloaded and the language used in the country are recognized. The language corresponding to one country code is
There may be more than one as in the Swiss example above. The language code table 1000 is created corresponding to the native language set by the user, and a dictionary is specified by the native language and the language code in the table. When the native language code as the native language information is changed, the language code table 100 is initialized (that is, the MCC is changed).
And language codes are erased). Alternatively, a new language code table 1000 is created, and the valid language code table is switched from the old one to the new one.

In the example of FIG. 10, language information for two MCCs is described, but it goes without saying that this list can be as long as the memory allows. The lower 4 bits of the first byte 1001 are the first byte 100
1 to the total number of bytes (T
otal Bytes). For example, here is the first
Of the third language code (3rd Language Code) of the fifth byte 1005, which is "5" in this example. First byte 100
The upper 4 bits of 1 are the most significant digit (MCC1 Dig) of the first MMC.
It indicates 1). The lower 4 bits of the second byte 1002 indicate the second digit (MCC1 Digit 2) of the first MMC. The upper 4 bits are the third digit of the first MMC (MCC1 D
igit3), and the first MMC (MCC
1) Make up. For example, in the example of the dictionary selection screen shown in FIG. 3, it is assumed that the user is in Switzerland.
C1 becomes “228”. The third byte 1003 is the first
Language code (1st Language Code). For example, following the example of the dictionary selection screen shown in FIG.
The language code is indicated by 03Hex. Similarly, the fourth byte is the second language code (2nd Language Cod
e), which is 00Hex in German. Fifth
Is the third language code (3rd Language Code)
In Italian, it is indicated by 02Hex. The sixth byte indicates the first data of a portion to be added when performing location registration in another country (or region).
Total number of language codes used in C (MCC2) area (To
tal Bytes). For example, here, it indicates the number of bytes from the sixth byte 1006 to the first language code (1st Language Code) of the eighth byte 1008. Therefore, in this example, it is "3". 6th byte 1
The upper 4 bits of 006 are the most significant digit of the second MMC (MCC2
Digit 1). The lower 4 bits of the seventh byte 1007 indicate the second digit (MCC2 Digit 2) of the second MMC. The upper 4 bits are the third digit of the second MMC (MCC2D
igit3), and these three digits indicate the second MMC (MCC
2) Make up. For example, here, the next eighth byte 1008 is the first language code (1st Language Code).
Indicates that the country uses the same language as the third byte 1003. In this example, French is used, so MCC2 represents France. "
208 ". In the example described in the automatic download display example of FIG.
4 "enters the MCC2, and 01Hex representing English is entered as the fourth language code (4th Language Code). The ninth byte 1009 contains a code (for example, FFHex) representing the end of the language code table data. In addition, the end of data is easily detected when referring to this table.

FIG. 11 shows a language data address table 1
100 is shown. This is a table that links language codes with dictionary data that is actually used. The first byte 1101 contains a first language code (1st Language Cod).
e) is included, and when using a dictionary, the dictionary data is searched by referring to this code. In the second to fifth bytes 1102 (1st Language Data Address), for example, the native language and the first language (1st Language) actually used are used.
The address (Address) of the memory in which the dictionary function data between them is stored is described. In the present embodiment, the above-described EEPROM 223 or memory stick is used as the memory. In this table, similarly, addresses can be set up to n as long as the memory capacity permits. The reason why the code indicating the end of the table element is not included in this table is that the number of language codes can be known by referring to the language code table 1000 in FIG. Note that the language data address table 1100 of FIG. 11 is used when the location registration is performed frequently and the number of languages increases, and when the memory capacity is insufficient, the less frequently used and older dictionary data is deleted. This is because, considering that a new address is added, the search can be easily performed because there is an intermediate table for managing the address where the dictionary data starts.

For example, an access counter indicating the frequency of use of each dictionary is set in each dictionary data area. The latest use date and time information may be recorded in addition to the use frequency. These dictionary use history information can be used in an automatic download process of FIG. 12 described later. The retention of such usage history information is not limited to the language data address table 1100, but may be in another table or a dedicated data storage area.

FIG. 12 shows an example of the automatic download process in the portable terminal. This process is started each time the mobile terminal performs location registration. First, an MCC is obtained based on the LAI from the base station (S1). Next, this MCC
MC that does not exist in language code table 1000
It is checked whether it is C (S2). If there is, the dictionary data does not need to be downloaded, so this processing is terminated. If it does not exist, it is determined that it has moved to a new country (or region). Next, the above-mentioned native language code is transmitted to the server (S3). The native language code sent here is
The MCC stored in the IMSI is used, or the language used for displaying the portable terminal selected in the language initial setting table 900 inside the SIM is used. That is, each functions as the native language information storage means in the present invention. Which one to use is fixedly set in advance or selectively set by the user. When the MCC stored in the IMSI is used as the native language code, the language can be specified on the server side.

The server that has received the native language code sets the L
The language code of the language used (not necessarily one) in the country indicated by the MMC in the AI, and the data capacity of dictionary data for translating between this language and the language specified by the received native language code To the mobile device. The server assumed in the present embodiment is a server such as an operator or a provider used in the country where the user is located, and this server includes at least a language used in the country and other languages. Provide dictionary data to users for translation between languages. Therefore, the dictionary provided to the user by the server is determined based on the language used in the country and the native language code given by the user. However, the server may be provided in common in a plurality of countries and provide dictionary data of a language group used in the plurality of countries. In this case, the server specifies the country where the user is located by, for example, receiving a notification of the MCC of the country where the user is located from the portable terminal, and prepares the language used in that country in advance. Recognize based on a table or the like.

The portable terminal receives the language code of the language used in the country and the data capacity of the dictionary data transmitted from the server (S4), and receives the language code table 1000.
Is further checked to see if the same language code as the received language code is stored in the language code table 1000 (S5). If the same language data exists, the dictionary data has already been stored in the mobile terminal.
This processing ends. If it is a new language code that does not exist in the language code table 1000, the process proceeds to a process of downloading dictionary data between the language of the language code and the user's native language.

Therefore, it is confirmed whether or not the memory for storing the dictionary data has a free space capable of accommodating the dictionary data of the data capacity (S6). Since the memory allocated to dictionary data in the mobile terminal is limited, if the amount of dictionary data to be downloaded exceeds the free memory capacity, secure unused memory by deleting old unused dictionary data. It is necessary. If there is enough space, the process immediately proceeds to the dictionary data transmission request (S12). On the other hand, when the free space is insufficient, in order to secure a memory area for new dictionary data, an unused language (dictionary) having a low priority is listed with reference to the use history information. (S7). If it is determined based on the result that there is an unused dictionary (S8, Yes), the dictionary is set as a candidate for deletion. If there is no unused dictionary, the dictionary that is used less frequently is deleted, and a dictionary data use frequency check is performed based on the use history information (S
9). In this way, a deleteable dictionary list up process is performed (S10). When a candidate is selected in this way, candidate dictionary data deletion processing is performed (S11). This processing includes rewriting (updating) of each of the tables 1000 and 1100 and the like.

After securing a free memory area for storing new dictionary data in this way, a dictionary data transmission request is made (S12), and the server is notified that data reception is ready. Next, the received dictionary data is received (S13), and writing is sequentially performed on a previously secured or designated memory area. The language code table 1000 is updated based on the language code of the sent dictionary (S14), and then the language data address table 1100 is updated (S15), and all the processing ends.

The above-described processing in FIG. 12 assumes that all the mobile terminals automatically execute the processing without depending on the user's instruction. May be inserted. For example, when there are a plurality of languages used in the country, selective download of some of them may be accepted, or the user's consent may be obtained when deleting the dictionary or executing the download. In such a case, the initiative of the processing is solely in the portable terminal. Therefore, the "automatic" town load processing of the present invention can include this degree of user involvement.

FIG. 13 shows a process executed on the portable terminal when the user's native language on the portable terminal is changed.
The "native language" here is a language that is a reference of the translation dictionary, and is not necessarily determined by the user's nationality or address. The change of the user's native language is mainly performed by changing the first language code or changing the priority when the setting is made such that the highest priority display language of the language initial setting table 900 is used as the native language in translation. Can occur. Such a situation may occur when translation between languages other than the native language normally used by the user of the mobile terminal is required, or when the user of the mobile terminal changes.

When the native language is changed, the portable terminal updates the language code table 1000 (S21), and also updates the language data address table 1100 (S22).
These updates refer to the current language code table 1000
Is initialized, and the language data address table is also initialized. As a result, the dictionary data stored in the memory becomes invalid. However, if a dictionary for a new native language happens to exist in the portable terminal, the language code of the dictionary may be left at the time of this update. For example, if the native language is Japanese and there are Japanese-English, Japanese-German, and Japanese-French dictionaries, and the native language is switched to English, the Japanese-English dictionary is left as it is. It is possible to use it. Here, the expression “Japanese-English” means not only bidirectional translation from Japanese to English but also English to Japanese (the same applies to other languages). Thereafter, when the position registration of the mobile terminal is performed, the automatic download process described in FIG. 12 is started, and the download of the new native language and the dictionary data suitable for the country are automatically performed.

In the above, the case where only a single table 1000 or 1100 exists in the portable terminal was considered. However, a new table is additionally created for each different native language code, and the new table is created according to the native language code. It is also possible to switch the table to be used.

According to the processing at the time of changing the native language of FIG. 13, it is possible to automatically download new dictionary data in response to the change of the native language automatically.

Finally, the processing when the memory stick is replaced when the memory stick is used as the storage device for storing the dictionary data will be described. As described above, when the dictionary data is stored in the memory stick, the language code table 1000 and the language data address table 1100 can be stored in the storage device of the terminal main body side. It is desirable for management to be held in a memory stick.
FIG. 14 shows a flowchart of a process executed when such a memory stick is replaced.

First, the native language code set in the portable terminal is confirmed (S31), and it is checked whether or not dictionary data corresponding to the native language exists in the newly inserted Memory Stick. (S32). If there is, this process ends. If not, it is confirmed whether or not it is necessary to store dictionary data in this memory stick (S33). This can be determined by the portable terminal by inquiring the user or by initial setting. The initial setting is a fixed or selectively set item such as not storing dictionary data in a memory stick dedicated to music data.

If the dictionary data is unnecessary, this processing is terminated. If dictionary data is required, a language code table 1000 for the native language is newly created (S3).
4). Further, a language data address table 1100 is newly created (S35). Then, at the time of location registration,
The automatic download process described in 2 is started. In that process, the table 100 as a result of the process of FIG.
If the content of 0 is blank, the MCC obtained from the base station is determined as a new MCC in step S2, and
In step S5, the language of the country is determined to be a new language, and the corresponding dictionary data is downloaded to the memory stick. If dictionary data exists in the memory stick, it is checked based on the contents of the table 1000 whether the MCC acquired from the base station is new, and if new, the language code of the country already exists, The necessity of download is determined according to the check result.

As described above, according to the process at the time of replacing the memory stick shown in FIG. 14, it is possible to automatically make an appropriate judgment at the time of replacing the memory stick and automatically download necessary dictionary data. Also, duplicate download processing of the same dictionary data can be eliminated.

According to the above embodiment, the following effects can be obtained. 1. Eliminates the need to carry a paper-based publication dictionary. 2. It is possible to download a dictionary for automatically converting between the visited language and the native language from a server on the network. 3. Downloaded dictionaries can always be described with the latest information. 4. Speech synthesis or speech recognition data is also downloaded along with the dictionary, so that pronunciation and the like can be confirmed using speech input / output of the portable terminal. Or the dictionary is opened by voice input. 5. The dictionary can be selected even if the selected language recorded in the language initial setting table of the SIM is set as the native language. 6. A special device and processing for position detection, such as a conventional GPS, are not required.

Although the preferred embodiment of the present invention has been described above, various modifications and changes other than those described above are possible. For example, in the above example, the language code table 1000 (FIG. 10) is described as being dynamically updated, storing a set of a country code (MMC) and a corresponding language code of the country where the dictionary was downloaded. But
It may be a table in which a set of country codes and language codes of languages used in the countries for all (or major) countries is statically stored in advance. In this case, the presence or absence of the dictionary in the portable terminal can be checked based on the language data address table 1100 instead of the language code table 1000. In this case, it is not necessary to notify the language code from the server in step S4 in FIG.

[0051]

According to the present invention, a dictionary between a language used in a visited country (or region) and a native language is automatically taken in and used as a user of a portable terminal device moves. It becomes possible. Therefore, when the user needs the dictionary without being particularly conscious, the necessary dictionary data is already loaded in the portable terminal device, and the user can be more convenient. . Also, GPS
Since a special position detecting device such as that described above is not required, the cost of the device can be reduced.
