FIG. 1 is a block diagram showing the configuration of a portable mobile telephone terminal according to the present invention, which is based on a standard such as IMT-2000. The terminal 1 sets up a radio link to the nearest base station of the mobile radio communication network via the communication radio interface 2 and the antenna 3, and executes digital conversion of the received signal.
The control unit 6 is a central processing unit (CPU) that controls the overall operation of the mobile terminal 1.
Unit) and various programs executed by the CPU. In the present embodiment, a program for realizing a flowchart described later is mounted on the CPU. Further, the control unit 6 executes call processing setting processing based on a selection signal from the keypad 7 to set a communication channel with the other party, and a basic performance inherent to the mobile phone is achieved by a communication circuit including the speaker 10 and the microphone 11. I will provide a.

  As shown in FIG. 2, which is a side view of the mobile terminal 1, the electronic tag reader 12 is mounted on the opposite side of the display panel (LCD) 9. When activated by the control unit 6, destination information Is stored in the flash memory 8. The storage area of the flash memory 8 is divided into a plurality of personal data, and the destination information read from the electronic tag is stored in the corresponding area as personal data. The stored destination information is displayed on the display panel 9 together with the position of the terminal acquired from the GPS satellite.

  The keypad 7 is provided with a GPS function button 14. When the user presses this button, the GPS wireless interface 4 is activated, receives signals from a plurality of GPS satellites via the antenna 5, and processes the received signals. The current position information of the terminal is acquired and supplied to the control unit 6.

The UIM (User Identity Module) card 13 is an IMSI (International
The user of the mobile terminal is specified by “Mobile Subscriber Identifier”. When using the mobile terminal 1, the user inserts the UIM card 13 into a slot provided in the mobile terminal. Thereby, the user can use a conversation with another person and various contracted services (such as browsing a website) via the mobile mobile communication network.

  FIG. 3 shows an example of a bulletin board 20 that posts a neighborhood street map 21 installed in front of a station or the like. Landmarks such as building A and building B are posted on the street map, and a plurality of electronic tags 23 corresponding to the names 22 of these buildings are installed. When the electronic tag reader 12 of the portable terminal 1 is brought close to one of the electronic tags 23 by the user, the electronic tag reader 12 reads the destination information stored in the electronic tag.

  4 and 5 show flowcharts executed by the control unit 6. First, when the user presses the GPS button 14 within 1 second or less (step 401), the control unit 6 proceeds to step 402 and determines whether or not destination information has been read from the electronic tag. If the user stops in front of the bulletin board 20 and brings the electronic tag reader 12 close to one of the electronic tags 23, the determination in step 402 becomes YES, and the destination information read in step 403 is stored in the memory 8.

  As shown in FIG. 6, the destination information is stored in the individual area. The destination information includes a plurality of entries 501 for a plurality of destinations, each entry is further divided into a plurality of fields, the building name is in the field 502, the latitude and longitude are in the fields 503 and 504, and the address is in the field. Stored at 505.

Returning to FIG. 4, the control unit 6 displays on the display panel (LCD) that the reading of data is completed in step 404. When the user recognizes this “reading completion” display and presses the GPS button 14 for 1 second or longer (step 405), the GPS function screen shown in FIG. 7 is displayed on the display panel 9 (step 406).

  As shown in FIG. 7, the GPS function screen includes selection items of “acquisition of terminal location information” 601, “acquisition of destination information” 602, and “end” 603, and the user selects one of these items. . When the user selects item 601 (acquisition of terminal location information) (step 407), the control unit 6 activates the GPS wireless interface 4 to receive signals from a plurality of GPS satellites, and processes the received signals. Terminal location information is obtained (step 408).

  Next, in step 409, the control unit 6 reads the map information from the flash memory 8 and displays it on the display panel 9 as a composite screen with the terminal position information obtained in step 408. (See FIG. 8).

  Next, when the user presses the GPS button for 1 second or longer (step 410), the GPS function screen shown in FIG. 7 is displayed again (step 411, FIG. 5). When the user selects item 602 (acquisition of destination information) (step 412), the control unit 6 reads a list of destination names from the memory 8 and displays the destination selection screen shown in FIG. 9 on the display panel ( Step 413). On this destination selection screen, a button mark 801 for spot cooking is arranged beside each building name. When the user selects a button mark 801 that is bitter about the target building name (step 414), the latitude and longitude of the selected building name are read from the memory 8 and displayed as the destination location on the composite screen (step 415). .

  Accordingly, the user goes to the destination while relying on the map on the display panel 9 while carrying the mobile terminal 1. Whenever the user wants to know his / her position on this road, the current position on the screen can be updated.

  That is, after the screen is displayed in step 415, if the user presses the GPS button 14 for 1 second or less in step 416, the control unit 6 proceeds to step 417 and activates the GPS wireless interface 4 to detect the current position of the terminal. The current position on the screen is updated (step 418), and the process returns to step 416. Thus, the current position can be updated until the user reaches the destination by pressing the GPS button 14 again for 1 second or less.

When the user presses the GPS button 14 for 1 second or longer in step 416, the control unit 6 returns to step 411 and displays the GPS function screen again. Therefore, when the user wants to display the building he / she sees on the display panel as a landmark on the way to the destination and confirm the relationship with his / her current position, the user presses the GPS button 14 for 1 second or longer in step 416. In step 411, the GPS function screen is displayed, "Destination information acquisition" is selected (step 412), the destination list is read from the memory 8 (step 413), and the corresponding building name is selected (step 414). ), The position of the building you see can be additionally displayed on the display screen. When the user again presses the GPS button 14 for 1 second or more in step 416 and repeats the above operation, the position of the next building that has been seen can be additionally displayed on the screen.
