Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone terminal, and more particularly to an electric field strength notification function in a mobile phone terminal that measures electric field strength in the vicinity and notifies the level.
[0002]
[Prior art]
Conventionally, when the electric field strength is weak in hotels, apartments, etc., a phenomenon may occur in which an incoming call is not received or a call is disconnected many times during use depending on the place of use. Usually, the electric field strength can be confirmed on the LCD display, but detailed information is not known. The actual situation is that the level of the electric field strength cannot be determined only by the approximate electric field strength displayed on the mobile phone terminal. In order to cope with this type of phenomenon, the volume is reduced according to the electric field strength level measured during a call, and the user of the mobile phone terminal is notified (for example, Patent Document 1). Further, the electric field level is measured by an electric field intensity measuring device, and the maximum value is stored and displayed in comparison with a threshold value (for example, Patent Document 2).

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
Referring to FIG. 1, a diagram in which a mobile phone terminal 10 is communicating with a base station 20 is shown. The mobile phone terminal 10 includes an antenna unit 1, a radio unit 2, a signal generation unit 3, and a speaker unit 4. A liquid crystal display (LCD) unit 5, a memory unit 6, and a central control unit 7. The electric field strength detector 21 in the wireless unit 2 detects the electric field strength level. The signal generator 3 generates a signal for notifying the electric field intensity level detected by the electric field intensity detector 21. The speaker unit 4 outputs the electric field strength level with sound, and the LCD unit 5 visually displays the electric field strength level. The memory unit 6 stores a program for operating the mobile phone terminal, and stores a reference electric field intensity level and an electric field intensity level detected during movement. The central control unit 7 reads out both electric field intensity levels from the memory unit 6 and compares them, and outputs the result to the speaker unit 4 or the LCD unit 5 by volume or display.
[0012]
Next, the operation according to the embodiment of the present invention will be described with reference to FIGS. When searching for the electric field strength in a specific limited place where the electric field strength is weak, such as a hotel room or an apartment, the user of the mobile phone terminal sets the electric field strength detection mode by key operation (step 1: S1). Abbreviated name, the same applies hereinafter), either notification by volume or notification by display is selected (S2). The central control unit 7 detects the electric field level at the current location detected by the electric field intensity detection unit 21 (S3). In the case of notification by volume, the signal generator 3 sends a level of a constant signal sent from the speaker 4 (S4), and determines the volume of the current electric field strength by key operation (S5). By using this constant signal, the change in volume can be easily understood. In the case of notification by display, the level of the electric field strength is detected (S3), and the level is determined to be easy to understand, such as “0” (S6).
[0013]
With the level setting completed, the user moves within a limited range (S7). At that time, the central controller 7 always detects the level detected by the electric field intensity detector 21. When the detected level is higher than the initially set electric field strength level, the volume or LCD display number is increased, and conversely when the electric field strength is low, the volume and display number are decreased (S8). Further, the value at the time when the electric field intensity level becomes maximum after starting the movement is stored in the memory unit 6 (S9). In the case of notification by display, the electric field strength level is always detected, but the result when the level is the highest after the detection is started is also displayed (S11). This makes it easy to determine whether the electric field strength at the current location is maximum. In the case of notification by volume, the measurement is temporarily interrupted during detection, the volume at the highest level can be called after detection is started, and detection is started again after confirmation (S10). In this way, the place with the highest electric field strength level is searched.
[0014]
Next, another embodiment will be described. The electric field strength level at a place where the call is likely to be interrupted is detected by the method described above, and the result is stored in the memory unit 6. The central control unit 7 always compares the value detected by the electric field intensity detection unit 21 with the stored value, and when the detection level becomes lower than the stored value, the warning display by the LCD unit 5 or the warning sound from the speaker unit 4 Is sent out. As a result, when the user moves to a place where the radio wave condition is bad, the user can know that the call is at a level where the call is easily interrupted.
[0015]
【The invention's effect】
As described above, according to the present invention, a detailed electric field strength level is notified to the user by volume or display in a specific limited place where the electric field strength is weak. As a result, it is possible to easily search for a place where the electric field strength level is the highest within a limited range. Therefore, it is possible to reduce the phenomenon that the incoming / outgoing call cannot be made or the call is interrupted by waiting or talking at a place where the searched electric field strength level is large.
