  The present invention is configured and operated as described below, so that it is easy to move to a position where the antenna sensitivity is good without mounting a large-capacity memory or exchanging large-capacity map data. The effect that it can display in a short time is acquired.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a mobile phone according to an embodiment of the present invention. 1, a mobile phone 1 includes an antenna 11, a receiving circuit 12, a sensitivity detection circuit 13, a direction detection circuit 14, a position detection circuit 15, an information storage circuit 16, a display circuit 17, and an LCD (Liquid Crystal). Display) display unit 18.

  The cellular phone 1 receives a radio wave from the receiving circuit 12 through the antenna 11, checks the sensitivity state (radio wave state) of the antenna 11 with the sensitivity detection circuit 13, and detects a position detection circuit [eg, GPS (Global Positioning System), etc. ] And a direction detection circuit (for example, a magnetic compass) 14 are collected, and the sensitivity and positional relationship of the antenna 11 at that time are collected and stored in the information storage circuit 16 as data.

In this case, the mobile phone 1 detects the position with the position detection circuit 15 until it enters the building, and when it enters the building, the direction detection circuit 14 detects the position and maps the position while the antenna 11 has a good sensitivity. A method of accumulating as data can be considered.
It should be noted that the direction detection circuit 14 is small enough to be mounted on the mobile phone 1, so that the mobile phone 1 is in any state so that the ground direction is lowered by a weight, indicating north as a magnetic compass, Use equipment that can measure altitude so that the number of floors can be determined.

  Further, the mapping by the direction detection circuit 14 is based on the point inside the building and stores information on which direction the direction detection circuit 14 is moving from the position and sensitivity information of the antenna 11. If the number of floors in the building changes, it changes to a three-dimensional point setting, and the position is mapped.

  Thereafter, when the mobile phone 1 performs reception with the antenna 11 having poor sensitivity, the direction to the position where the antenna 11 has good sensitivity is judged by the display circuit 17 and an arrow or the like to the LCD display unit 18 is displayed. The direction to the position where the sensitivity of the antenna 11 is good is notified by display, LED (Light Emitting Diode) lighting 19 and voice announcement 20.

  In this embodiment, since the sensitivity of the antenna 11 in a building such as a company differs depending on the location, a location where the sensitivity of the antenna 11 by a mobile phone or the like is good is measured by the position detection circuit 15 or the direction detection circuit 14 and is carried in advance. The information is stored in a telephone or the like, and the direction to a place where the sensitivity of the antenna 11 is good is notified during communication or the like.

  Further, in this embodiment, when the current position is a poor sensitivity of the antenna 11, the shortest direction to the position where the sensitivity of the antenna 11 is good is shown at the location where the current location has moved before, and the position is displayed in units of positions. Instead of indicating the direction. In the case of displaying up to the distance, a method of deriving from the approximate distance in the number of steps taken, such as a pedometer (registered trademark), can be considered.

  FIG. 2 is a diagram showing a display example of the LCD display unit 18 of FIG. 1, and FIG. 3 is a flowchart showing the operation of the mobile phone 1 according to one embodiment of the present invention. The operation of the antenna sensitivity good position display method of the mobile phone 1 according to one embodiment of the present invention will be described with reference to FIGS.

  When the operation of a preset operation button (not shown) or the like is performed, the mobile phone 1 is a communication process (step S1 in FIG. 3), and if the sensitivity of the antenna 11 is good (step S5 in FIG. 3), Proceed to communication operation.

  If the mobile phone 1 is not a communication process (step S1 in FIG. 3), it is determined whether it is a position detection process with good antenna sensitivity (step S2 in FIG. 3). If the mobile phone 1 is a position detection process with good antenna sensitivity, the position is detected by the position detection circuit 15 if it is outside the building, or by the direction detection circuit 14 if it is inside the building (step S3 in FIG. 3). , The position where the sensitivity of the antenna 11 is good is accumulated as data in the information storage circuit 16 (step S4 in FIG. 3).

  One method for accumulating data in the information storage circuit 16 is whether the direction from the previous point (east, west, south, north, etc.) and the sensitivity of the antenna 11 at the previous point is better or worse. It is conceivable to store information or information on whether the floor has changed in the building (this information may be input by the user of the mobile phone 1).

  However, in this embodiment, regardless of whether it is inside or outside the building, the position where the start of the antenna sensitivity good position detection process is instructed, or when the position preset by GPS is detected, It is assumed that the direction for each predetermined time or predetermined distance from the point is accumulated together with information on the change in sensitivity of the antenna 11.

  On the other hand, if the cellular phone 1 is in communication processing (step S1 in FIG. 3) and the sensitivity of the antenna 11 is not good (step S5 in FIG. 3), the sensitivity of the antenna 11 is good based on the information stored in the information storage circuit 16. The direction to the position is determined (step S6 in FIG. 3), the direction to the position where the sensitivity of the antenna 11 is good is indicated by an arrow on the LCD display unit 18 (see FIG. 2), LED lighting 19 and voice announcement 20 are notified. (Step S7 in FIG. 3).

  At this time, if the sensitivity of the antenna 11 at the previous point is better than the current point in the data stored in the information storage circuit 16, the cellular phone 1 inverts the information in the direction stored in the information storage circuit 16 ( 180 degree rotation), and an arrow display on the LCD display unit 18, LED lighting 19, and voice announcement 20 are notified. If the sensitivity of the antenna 11 at the previous point is worse than the current point, the mobile phone 1 displays the current position as a position where the sensitivity of the antenna 11 is good.

  As described above, in this embodiment, the position of the place where the sensitivity is good is stored in the information storage circuit 16 as information using the position detection circuit 15 and the direction detection circuit 14 in the sensitivity detection circuit 13 that detects the sensitivity of the antenna 11. The location of the communication location is confirmed by the sensitivity detection circuit 13, and if it is bad, the location of the location is confirmed by the direction detection circuit 14 and compared with the location information in the information storage circuit 16, and the LCD display unit The location information with good sensitivity of the antenna 11 is notified by the arrow display to 18, the LED lighting 19, and the voice announcement 20.

  Therefore, in the present embodiment, the information on the sensitivity of the antenna 11 and the position information or the direction information are simply stored in the information storage circuit 16, so that a large-capacity map data or the like can be obtained without mounting a large-capacity memory. Exchange is also unnecessary. However, data for each frequently visited place (for example, a company or a station) is stored in the information storage circuit 16 in advance, and the place data may be read at a reference point. The information stored in the information storage circuit 16 may be deleted or overwritten every time the above-described antenna sensitivity good position detection process is started.

  Further, in this embodiment, even if the call is disconnected immediately after receiving an incoming call at a place where the sensitivity (radio wave condition) of the antenna 11 is bad, the sensitivity of the antenna 11 is good by executing the above display method. You can go to the place immediately and never miss an important story.

  Furthermore, in the present embodiment, even when communication is performed from this side, the call is made at a place where the sensitivity of the antenna 11 is good, so that the other party of the call is not uncomfortable.

  Furthermore, in this embodiment, a floor plan in the building and information on a place with good sensitivity of the antenna 11 are obtained in advance by the mobile phone 1, and even if a sudden call comes based on the information, the user can talk comfortably. You can move to a place where you can, and know your position to some extent, so it will be a guide to where you want to go.
