Abstract

A mobile device comprises at least a program starter, a communication controller, a display controller, a display portion, and an instruction portion. The mobile device receives report information that is emitted in a predetermined period by a guidance information terminal upon entering the communication area of the guidance information terminal in a state where a guidance information display application has been started by the program starter. The mobile device causes the display portion to display a dialog screen for issuing an instruction with regard to whether to acquire guidance information by means of the display controller upon reception of the report information. When the acquisition of guidance information has been instructed by the instruction portion, the mobile device issues a request to the guidance information terminal to transmit the guidance information by means of the communication controller and receives the guidance information. The guidance information thus received is displayed on the display portion by means of the display controller.

Claims

1. A communication terminal, comprising:

starting means for starting an application program for displaying supply information that is transmitted by an external device;

reception means for receiving report information that is emitted by the external device and which communicates the existence of the external device;

display control means for causing display means to display a screen for issuing an instruction with regard to whether the supply information is to be acquired upon reception of the report information by the reception means in a state where the application program has been started by the starting means; and

instruction means for issuing an instruction to acquire the supply information via the screen that is displayed by the display control means,

wherein the reception means receive the supply information by issuing a request to the external device to transmit the supply information when acquisition of the supply information has been instructed by the instruction means; and

the display control means cause the display means to display the supply information received by the reception means.

2. The communication terminal according to claim 1, wherein the supply information is information with little temporal variation.

3. The communication terminal according to claim 1, wherein the supply information is link information indicating a connection destination other than the external device;

the reception means request transmission of display information to the connection destination indicated by the link information and receive the display information; and

the display control means cause the display means to display the display information received by the reception means.

4. The communication terminal according to claim 3, wherein the display information is domestic information of the connection destination;

and

the reception means request the transmission of the domestic information to the connection destination indicated by the link information via an international line and receive the domestic information.

5. An information supply system, comprising:

the communication terminal according to claim 1;

and

an external device,

wherein the external device transmits the supply information in accordance with a request from the communication terminal.

6. An information supply method implemented by a communication terminal that is capable of communicating with an external device, comprising the steps of:

starting an application program for displaying supply information that is transmitted by the external device;

receiving report information that is emitted by the external device and which communicates the existence of the external device;

causing display means to display a screen for issuing an instruction with regard to whether the supply information is to be acquired upon reception of the report information in the report information reception step in a state where the application program has been started in the starting step;

issuing an instruction to acquire the supply information via the screen that was displayed in the instruction screen display control step;

receiving the supply information by issuing a request to the external device to transmit the supply information when acquisition of the supply information has been instructed in the instruction step; and

causing the display means to display the supply information received in the supply information reception step.
