  FIG. 10 is a flowchart for explaining an example of execution of the third procedure among the three procedures constituting the communication support program.

  In step S214 in the flowchart of FIG. 8, “Please stop the rotational motion” is displayed on the LCD 11, and then “Do you want to send a mail or talk?” Is displayed on the LCD 11 (step S310). ). As an example of the screen displayed on the LCD 11 in step S310, the screen shown in FIG.

  When the user selects “send mail” to the mobile phone 1 by selecting “send mail” in (1) of FIG. 11 (step S311 Yes), as an example, FIG. As shown in (2), “Please send a mail with the mobile phone screen facing the front” is displayed on the LCD 11 (step S312). That is, in order to maintain the state in which the direction of sensitivity with high radiation intensity in the directivity of the antenna 12e of the mobile phone 1 when transmitting mail is directed to the base station that transmits high-intensity radio waves, step S312 is performed.

A value “5” is measured and indicates a state in which a radio wave transmitted from the base station D is received.

  As shown in (1) of FIG. 12, the sensitivity direction 1d having a high radiation intensity in the directivity of the antenna 12e of the mobile phone 1 receives a radio wave transmitted from the base station D and whose maximum radio wave intensity “5” is measured. The nose 2a of the user 2, that is, the front face of the user's face is positioned so as to face the mobile phone 1 so as to keep the state.

  On the other hand, in step S311, the user selects “call” without selecting “mail transmission” in (1) of FIG. 11, so that the user inputs “call execution” to the mobile phone 1. When it is made (No in step S311), the LCD 11 displays "Do you hold the phone with your right hand? Or do you hold the phone with your left hand?" (Step S313). As an example of the screen displayed on the LCD 11 in step S313, the screen shown in FIG.

  When the user selects “right hand” in (3) of FIG. 11 and the user inputs “hold the phone with the right hand” to the mobile phone 1 (step S314 Yes), as an example, FIG. As shown in (4), the LCD 11 displays "Please start the call by placing the right ear on the mobile phone while keeping the position of the mobile phone in the current state" (step S315). That is, when calling with the mobile phone 1 with the right hand, the sensitivity direction 1d having a high radiation intensity in the directivity of the antenna 12e of the mobile phone 1 is kept facing the base station that transmits a high-intensity radio wave. In order to do so, the content of step S315 is displayed on the LCD 11.

  The state in which the user is guided to the user using the LCD 11 in step S315 is the state shown in (2) of FIG. As shown in (2) of FIG. 12, a sensitivity direction 1d having a high radiation intensity in the directivity of the antenna 12e of the mobile phone 1 is transmitted from the base station D, and a radio wave for which the maximum radio field intensity “5” is measured is received. The right ear 2b of the user 2 is positioned so as to face the mobile phone 1 so as to keep the state.

  On the other hand, when the user selects “left hand” in the mobile phone 1 by selecting “left hand” in (3) of FIG. 11 (No in step S314), as an example As shown in FIG. 11 (5), the LCD 11 displays "Please start the call by placing the left ear on the mobile phone while keeping the position of the mobile phone in the current state" (step S316). That is, in the case of making a call with the mobile phone 1 with the left ear, the sensitivity direction 1d having a high radiation intensity in the directivity of the antenna 12e of the mobile phone 1 is kept facing the base station that transmits a high-intensity radio wave. Therefore, the content of step S316 is displayed on the LCD 11.

As described in steps S212 and S213, the base station identifier recorded in step S204 and the maximum radio field strength value for each base station are used to search for a base station that transmits a radio wave whose maximum radio field strength value is measured. However, the present invention is not limited to this configuration. In the step corresponding to step S204 in FIG. 3, only the maximum value of the radio wave intensity values recorded with the 360-degree rotation of the user is recorded. In step 8 corresponding to step S212 and step S213 of FIG. 8, the base station that transmits the radio wave for which the maximum radio wave intensity value recorded previously is measured may be searched. .

  In the communication support program described above, the user holding the mobile phone 1 rotates to detect the value of the strength of the radio wave received by the mobile phone 1, and the user performs the same exercise again. However, the configuration is not limited to this configuration. For example, the mobile phone 1 receives the signal while the user holding the mobile phone 1 first exercises. It is determined whether the mobile phone 1 is capable of wireless communication based on the intensity value of the radio wave to be transmitted, and if it is determined that wireless communication is possible, the user holding the mobile phone 1 is notified to stop exercising. In addition, the mobile phone 1 may be configured to notify the user so that the mobile phone 1 can maintain wireless communication.

  In the above communication support program, the configuration in which the user is guided using the LCD 11 has been described. However, the present invention is not limited to this configuration, and the content displayed on the LCD 11 is guided to the user from the speaker 14 as sound. May be.

  In the above communication support program, an example in which a message is displayed on the LCD 11 using characters has been described. However, the present invention is not limited to this example. For example, as shown in FIG. It may be configured to.
