When the mobile phone 10 moves into the service area of the cell base station / switching control station 2, it scans and monitors the control channel (CCH) and supplements the control channel with the maximum received electric field strength. After this location registration,
A communication sequence for a known call (outgoing) or incoming call (incoming) is executed.

Further, the GPS receiver 30 of the portable terminal 1
The current absolute position (latitude, longitude) by the global azimuth measurement (abbreviated as GPS measurement) system is detected. That is, at least three GPS satellites flying in the sky
The GPS radio waves Wa, Wb, and Wc transmitted by at are received by the planar polarization omnidirectional reception antenna 3 and the wireless reception unit 32, and the absolute position of the reception point is detected.

The absolute position information is detected by the digital signal processor 33, which processes spectrum despreading, distance measurement, Doppler measurement, and orbit database construction, and performs position calculation and moving speed direction calculation from these information.
The current absolute position information is transferred from the interface unit 38 to the mobile phone 10 by an instruction operation of the operation unit 34.

After the first absolute position is detected and transferred, in other words, when the absolute position information differs from the previous value, the new absolute position information is automatically transferred to the mobile phone 10. Is also good.

1 and 3, the map information language conversion communication system 5 receives the absolute position information and the language conversion instruction from the portable terminal 1 through the Internet access, and sends them to the map database device 7 and the multilingual database device 8, respectively. The map information and the display character information after the language conversion by the tracking processing are transmitted.

In this case, the control server 6 of the map information language conversion communication system 5 receives the absolute position information (latitude, longitude) from the portable terminal 1 in the roaming operation in a foreign country, and performs language conversion of the display characters. The control for providing the map information to the mobile terminal 1 from the Internet network 4 is executed.

In this case, the control server 6 reads out the map information stored in the map database device 7 in correspondence with the absolute position information from the portable terminal 1. In addition, the control server 6 converts the character information on the map information read from the map database device 7 into character information different from character information (which is basically a local character operated by roaming), for example, by using an HTM.

Determines that a language conversion instruction is to be captured (step S1).
4) When there is a language conversion instruction, the character information on the map information extracted from the map database device 7 is subjected to language conversion by the processing of the database device 8. For example, "Hangul" is converted into "Japanese" on the HTML description and a "flag F2" is set (step S15).

In this language conversion, it is convenient if the character description in the language of the country in which the roaming operation is in operation is also performed so that the name of a nearby store at the moving place can be easily found.

Further, the map information language conversion communication system 5
Transfers the contents (the map information in which the display characters are language-converted or the map information in which the display characters are displayed in the local language characters) stored as “flags F1 and F2” to the mobile phone 10 via a link (step S16).

In the memory 38. Thereafter, the outline map information is displayed, and then a specific position on the outline map information is designated from the operation unit 34, and the detailed map information is displayed on the screen of the mobile phone 10.

(2) First, the map information language conversion communication system 5 transfers the schematic map information to the mobile phone 10, and then the map information language conversion communication system 5 and the mobile phone 10
The command according to the detailed position indication of the mobile phone 10 is transferred on the link with
The detailed map information is extracted from the map database device 7 by tracking and transferred. Then, the mobile phone 10 displays the detailed map information on the screen (this communication sequence is omitted in FIG. 4).

On this detailed map screen, for example, one or both of the character descriptions in “Hangul” and “Japanese” are provided.

In FIG. 5, this example is a case where new map information and a transmission line are required after the transmission procedure and the processing procedure shown in FIG. In other words, this is a case where the user moves during the link setting between the map information language conversion communication system 5 and the mobile phone 10 and requests a new multilingual conversion such as the location.

In this case, as shown in FIG. 5, the operation unit 34 of the GPS receiver 30 is instructed to transfer the absolute position information by GPS measurement from the mobile phone 10 to the map information language conversion communication system 5 (step S3). ). In addition, the mobile phone 10 instructs language conversion as needed (step Sg). The map information language conversion communication system 5 performs the same processing as in the case of FIG. 4 (steps S10 to S1 in FIG. 4).
6), the contents (the map information in which the display characters are converted into the language or the map information in the local language) stored as the “flag F1, F2” are transferred to the mobile phone 10 via a link (step in FIG. 5). S17, S18, S19, S2

The portable telephone 10 processes the fetching of the map information in which the transferred display characters are language-converted or the local language map information in the same manner as in the case of FIG. 4 (steps Se and FIG. 4 in FIG. 4). Sh), and the screen is displayed (steps Sh and Si in FIG. 5).

In the above embodiment, the absolute position information is described as two-dimensional information of latitude and longitude.
A map display using absolute position information of longitude and altitude information is also possible. For example, when the current position is a high place such as a mountain, at least four GPS radio waves can be received, and the latitude, longitude, and altitude information can be obtained. in this case,
The map information stored in the map database device 7 can be displayed three-dimensionally by a three-dimensional simulation.

In the three-dimensional simulation, data processing and display processing are known as three-dimensional display by three-dimensional image processing and three-dimensional graphics, and detailed description thereof is omitted.

Further, the map information language conversion communication system 5
