In this case, the control server 6 transmits the position map information stored in the map database device 7 to the portable terminal 1.
A and 1B are read out in correspondence with the absolute position information. Further, the control server 6 converts the character information different from the character information on the position map information read from the map database device 7 into, for example, character information in HTML description (conversion of image / image characters is substantially difficult). Is converted by the multilingual database device 8. In this tracking process, for example, a relational database process is executed by SQL (Structured Query Language).

The web server 42 shown in FIG. 3 performs communication connection processing by TCP / IP, which is well known as Internet communication, and language processing function by HTML (HyperText Markup Language) (text, audio, JPEG still image or MPEG moving image processing by data compression). ), And HTTP (Hypertex
The transfer bi-directional communication by the hyperlink function by the T Transport Protocol), the file transfer by the FTP server 43, and the external application by the CGI (Common Gateway Interface) are respectively executed. A mobile phone for this purpose is equipped with a web browser for Internet access.

Further, the map database device 7 stores a bitmap image file for processing map information, for example, a TIFF (Tagged Image File Form).
Along with at), map information of a high-definition image is generated and processed by, for example, a PDF (Portable Document Format) file, which enables conversion of precise map information while maintaining the image at the time of creation regardless of the model and the font used.

Each of these devices performs a file transfer by a well-known IP packet by a TCP / IP link by bidirectional communication. The transfer processing on the Internet in this communication network is executed by an object instruction in HTTP (an instruction to a radio button, an anchor, a push button or the like by a coordinate input device such as a click / mouse). In this case, a transmission end description character (FIN) for opening the TCP connection, a transmission acknowledgment character (ACK), and the like are stored in the file format, and the file transfer is executed based on the identification.

A PS measurement is performed (step S1). Furthermore, it is determined that the measurement of the absolute position information has been completed, and the obtained absolute position information is transferred by the mobile phone 10 according to an instruction on the operation unit 34 (step S2).

The mobile phone 10 of the mobile terminal 1A makes a call to the mobile terminal 1B (step Sa). Next, a desired language conversion is instructed. For example, when requesting display characters in the language of the country where the roaming operation is performed or a language of another country, a predetermined language conversion instruction (for example, an instruction of a language code) is performed (step Sb). Next, the mobile terminal 1B
Is input (step Sc), and it is determined whether to take in the language conversion instruction information, the outgoing telephone number, and the absolute position information (step Sd).

After the portable telephone 10 of the portable terminal 1A determines that the language conversion instruction information, the originating telephone number, and the absolute position information have been completely taken in (step Sd), the portable telephone 1A transmits the call to the portable terminal 1B through the Internet network 4 (step Sd). S
e).

The mobile phone 10 of the mobile terminal 1B determines whether to take in the language conversion instruction information and the absolute position information from the mobile terminal 1A (step SA). The portable terminal 1B accesses the position map information providing communication system 5, establishes a wireless line connection (link), and transfers language conversion instruction information and absolute position information from the portable terminal 1A (step SB).

Further, the position map information providing communication system 5

Country number information in a telephone number taken through a location registration sequence with the mobile phone 10 (or a unique mobile terminal 1A, 1B that can be transferred from the cell base station / switching control station (BS / MCC) 2) The identification data is taken in (step S11).

Next, the position map information providing communication system 5
Determines the capture of the absolute position information transferred from the mobile terminal 1A to the mobile terminal 1B (step S12), and then extracts the map information corresponding to the absolute position information (latitude, longitude) from the map database device 7 by tracking. To set a "flag F1". The map information here is displayed in characters in the local language during roaming operation (step S13).

Further, the position map information providing communication system 5
Determines that a language conversion instruction is to be captured (step S1).
