2. Description of the Related Art A ringing tone for notifying reception from a cellular phone, a pager, or the like in a place where even a slight noise makes the atmosphere worse, such as a concert of classical music. Is sounded,
Very annoying to people around me.

[0003] Therefore, in a concert of classical music, it is often prohibited to put a mobile phone, a pager or the like in a reception waiting state, that is, to keep the power on. In addition, in hospitals, the discomfort caused by the ringing tone not only adversely affects the patient's medical condition, but also may cause a pacemaker or medical device to malfunction due to electromagnetic waves emitted from a mobile phone or a pager. In some places, the use of mobile phones and pagers is prohibited.

[0004] Similarly, in airplanes, there is a possibility that the instruments may malfunction due to electromagnetic waves, and thus use in some countries is prohibited. However, even in such a case, the user may inadvertently forget to turn off the power and inconvenience others.

Accordingly, an object of the present invention is to issue a warning when a mobile phone, pager, or the like that is waiting for reception exists.

[0006]

In order to achieve the above object, a wireless portable communication device detecting device according to the first aspect of the present invention determines whether a wireless portable communication device is in a reception waiting state. It is characterized by comprising a determining means for determining, and a warning means for issuing a warning when the determining means determines that the wireless portable communication device is in a reception waiting state.

In this wireless portable communication device detection device, first, the determining means determines whether or not there is a wireless portable communication device in a reception waiting state. When the determining unit determines that there is a wireless portable communication device in a reception waiting state, the warning unit issues a warning and notifies the owner of the wireless portable communication device or a supervisor.

As described above, the wireless portable communication device detecting device can notify the owner or the monitor of the existence of the wireless portable communication device in a reception waiting state, so that a ringing tone sounds suddenly in a quiet place. Thus, it is possible to avoid a situation that may cause trouble to the surroundings.

According to a second aspect of the present invention, there is provided the wireless portable communication device detecting apparatus according to the first aspect, further comprising an electromagnetic wave detecting unit for detecting an electromagnetic wave, wherein the determining unit is configured to detect the electromagnetic wave by the electromagnetic wave detecting unit. The frequency of the detected electromagnetic wave is
It is characterized in that it is determined whether or not the wireless portable communication device is within a frequency band of an electromagnetic wave emitted to the outside when waiting for reception.

[0010] The wireless portable communication device emits a weak electromagnetic wave to the outside when waiting for reception. Then, the base station of the wireless communication receives the weak electromagnetic wave to grasp the approximate location of the wireless portable communication device. This wireless portable communication device detection device utilizes the characteristics of the communication system based on the wireless portable communication device as described above, and the frequency of the electromagnetic wave detected by the electromagnetic wave detection means is set to the reception state of the wireless portable communication device. By judging whether it is within the frequency band of weak electromagnetic waves emitted from
It is determined whether or not there is a wireless portable communication device in a reception waiting state.

As described above, the wireless portable communication device detection device is easy to detect (measure) because the frequency of the electromagnetic wave is used as a criterion, and furthermore, the wireless portable communication device in which the detected frequency of the electromagnetic wave is in a reception waiting state. Since the determination is based on whether or not the frequency is within the frequency band of the electromagnetic wave emitted from the communication device, an excellent effect that the determination is easy and accurate is exhibited.

Further, the invention described in claim 3 is the first invention.
The wireless portable communication device detection device according to the above, electromagnetic wave detection means for detecting an electromagnetic wave, and electromagnetic wave generation means for generating an electromagnetic wave by sequentially changing the frequency within a frequency band that the wireless portable communication device can receive The determination means, the electromagnetic wave detected by the electromagnetic wave detection means,
It is characterized in that it is determined whether or not the wireless portable communication device is an electromagnetic wave responsive to the electromagnetic wave emitted from the electromagnetic wave generating means.

In this wireless portable communication device detection device, the electromagnetic wave generating means emits an electromagnetic wave by sequentially changing the frequency. Since the frequency of the electromagnetic wave fluctuates sequentially within a frequency band that the wireless portable communication device can receive, if the frequency matches the frequency assigned to the wireless portable communication device in the reception waiting state, the wireless portable communication device sets this frequency. Electromagnetic waves are mistakenly recognized as electromagnetic waves for communication and received. After that, the wireless portable communication device
An electromagnetic wave having information for notifying the transmission source of the reception is emitted. Then, the electromagnetic wave detecting means detects the electromagnetic wave, the determining means, the electromagnetic wave detected by the electromagnetic wave detecting means, the electromagnetic wave emitted from the wireless portable communication device, that is,
It is determined whether or not the electromagnetic wave is responsive to the electromagnetic wave emitted from the electromagnetic wave generating means. Specifically, this determination is made by comprehensively determining, for example, the frequency and intensity of the detected electromagnetic wave, and the time elapsed from when the electromagnetic wave generating means emits the electromagnetic wave to when the electromagnetic wave detecting means detects the electromagnetic wave. It is done. In addition, the electromagnetic wave having information for notifying a transmission source that the wireless portable communication device has received the signal is as strong as the electromagnetic wave emitted during a call by the wireless portable communication device.

It has an excellent effect. Also, utilizing the feature that the wireless portable communication device detection device works on the wireless portable communication device, for example, if the frequency is changed in accordance with a certain law, the electromagnetic wave responding to the electromagnetic wave emitted from the electromagnetic wave generation means is also constant. It will be detected according to the law. Therefore, it can be easily determined whether the electromagnetic wave detected by the electromagnetic wave detection means is an electromagnetic wave emitted from the wireless portable communication device in a reception waiting state or a noise emitted from another electric device. Demonstrates even better effects.

For example, in a case where a gate is provided at the entrance of a concert hall or the like and a detection operation is performed one by one, it is only necessary to notify the presence or absence of the wireless portable communication device in the reception waiting state as described above. However, when a large number of people perform a detection operation in a large space at once, even if it is confirmed that there is a wireless mobile communication device waiting to receive, which person's wireless mobile communication device was detected Is often difficult to determine.

Therefore, an invention according to claim 4 is the wireless portable communication device detection device according to claim 2 or 3,
Further, the apparatus further includes a model determining unit that determines a model of the wireless portable communication device based on a frequency of the electromagnetic wave detected by the electromagnetic wave detecting unit.

In this wireless portable communication device detection device, the model determining means performs comparison of the frequency of the electromagnetic wave detected by the electromagnetic wave detecting means with the frequency band of the electromagnetic wave emitted from the wireless portable communication device for each model. It is determined whether the frequency of the electromagnetic wave detected by the electromagnetic wave detecting means belongs to the frequency band of the electromagnetic wave emitted from what kind of wireless portable communication device. That is, the type of the wireless portable communication device that is the source of the electromagnetic waves detected by the electromagnetic wave detecting means is determined.

For example, since the mobile phone and the pager use different frequency bands, the type of the source of the detected electromagnetic wave is determined by determining to which frequency band the frequency of the detected electromagnetic wave belongs. can do. In this manner, the wireless portable communication device detection device can recognize the model of the detected wireless portable communication device, so that the wireless portable communication device is in a reception waiting state even if the number of holders of the wireless portable communication device is large. An even more excellent effect that the holder of the wireless portable communication device can be specified to some extent is exhibited.

According to a fifth aspect of the present invention, there is provided a wireless portable communication device detecting device for transmitting a call signal for each frequency by sequentially changing a frequency within a frequency band receivable by the wireless portable communication device. It is characterized by having. In this wireless portable communication device detection device, the transmission means transmits the call signal while sequentially changing the frequency within a frequency band that can be received by the wireless portable communication device. Then, when the sequentially fluctuating frequency matches the frequency assigned to the wireless portable communication device in the reception waiting state, the wireless portable communication device mistakenly identifies this call signal as a call signal from the base station. Rings, to notify the owner. Then, the ringing tone informs the owner or the monitor of the existence of the wireless portable communication device in the reception waiting state.

As described above, the wireless portable communication device detecting device forcibly sounds a ringing tone from the wireless portable communication device in the reception waiting state, so that the existence of the wireless portable communication device in the reception waiting state is further facilitated. In addition, a more excellent effect of being able to grasp accurately is exhibited.

Further, the wireless portable communication device detecting device is
The owner can be made aware of the existence of the wireless portable communication device in the reception waiting state, and the owner can turn off the power. Therefore, the effect that the burden on the monitor can be reduced is also exhibited. Further, as described above, according to the wireless portable communication device detection device, the wireless portable communication device in a reception waiting state, that is, the wireless portable communication device in a communicable state is detected, the power is turned off, and the wireless communication is performed. Since it can be prevented from being performed, there is also obtained an effect that an adverse effect caused by an electromagnetic wave generated from the wireless portable communication device, specifically, a malfunction of a medical device or the like can be avoided.

Although a portable telephone and a pager have been described as examples of the wireless portable communication device, the same effect can be obtained by other than these two types as long as they can communicate by electromagnetic waves.
