DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device and a method for preventing use of a mobile phone, and more particularly, to bring a powered-on mobile phone into a place where use of the mobile phone is prohibited or to make a call. The present invention relates to a technique for issuing a warning by voice or other notification means when a warning is issued.

[0002]

2. Description of the Related Art In recent years, wireless telephones such as portable telephones and PHSs have been reduced in size, price, and personalized, and the penetration rate has been rapidly increasing. The miniaturization of mobile phones has made it possible to carry them anywhere without having to worry about having them.

[0003] Since incoming calls of mobile phones can be made at any time and place, ringing tones and voices in public places such as movie theaters, theaters, restaurants, and conference halls cause annoyance to others. In addition, bringing a mobile phone to a hospital may cause a medical device to malfunction due to electromagnetic waves emitted from the mobile phone, and in the worst case, may be life-threatening.

[0004] As a countermeasure against the use of a portable telephone which may cause trouble for others, there are a method of reducing a sound leaking outside and a method of using a vibrator instead of a ringtone. For example, in an apparatus described in Japanese Patent Application Laid-Open No. 07-058833, a sound having a phase opposite to that of a talking voice is output from a speaker, thereby suppressing a talking voice that can be heard outside.

[0005] In the device described in Japanese Patent Application Laid-Open No. 09-84141, an incoming call is detected by an earphone or a vibration device so that a ringing tone is not emitted. In addition, it has been considered that the building has a structure for blocking radio waves from mobile phones.

[0006]

While these methods are useful for reducing ringtones and voices, they require modifying existing mobile phones or purchasing new ones.
The mobile phone owner has to pay the cost directly,
It seems difficult for the owner to understand this burden.

[0007] Further, it is not realistic to make a building a structure that blocks radio waves of a mobile phone because it requires a large amount of cost.

[0008] Furthermore, since electromagnetic waves from the mobile phone are not stopped, the danger of malfunction of medical equipment and the like has not been eliminated.

In order to stop electromagnetic waves from a mobile phone,
It is necessary to turn off the mobile phone, but at present there is no technical means to directly alert the user of the mobile phone and to prevent bringing the mobile phone with the power on. That is the current situation. If the owner is unaware, the effect of the notice is ineffective, and the notice itself may be overlooked.

Therefore, the present invention does not impose a direct cost burden on the owner of the mobile phone, and may inconvenience others, such as a movie theater, a theater, a restaurant, a conference hall, and the use of the mobile phone is prohibited. It is an object of the present invention to prevent the use of a mobile phone in a place where the mobile phone is used, and to prevent a portable phone from being brought into a place where the use of the mobile phone is prohibited.

[0011]

In order to solve the above-mentioned problems, a portable telephone use preventing apparatus according to the present invention comprises: a receiving means for receiving a call control signal transmitted from a mobile phone; Signal identification means for decoding the identification number, communication means for notifying the mobile phone base station of the subscriber identification number identified by the signal identification means via a telephone line, etc., and the subscriber identification number notified by the notification means And a means for interrupting a call during a call at the corresponding terminal and sending out guidance by voice or the like. Also,
Transmitting means for transmitting a pseudo base station signal similar to the base station signal; receiving means for receiving a call position registration signal transmitted from the mobile phone; and a position registration signal transmitted by the mobile phone receiving the pseudo base station signal. Means for outputting a lock signal to an opening / closing mechanism such as an entrance door during reception.

[0012]

[0013] In some cases, the sound itself that calls for attention is annoying to the surrounding people. In order to prevent this, in the device according to the first aspect, it is possible to interrupt a call during a call and give attention to the use of the mobile phone without disturbing a nearby person.

It is assumed that the area number included in the pseudo base station signal is different from the area number included in the signal transmitted from the base station serving the place where the device is located. Upon receiving the pseudo base station signal, the mobile phone determines that the area has changed, and transmits a location registration request signal. In response to the position registration request signal, the use of the mobile phone is warned. The mobile phone can be detected not only during a call but also when the power is turned on.

The device according to the second aspect can lock an automatic door at the entrance when a mobile phone is detected, and can prevent a mobile phone from being turned on.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION

The signal is input to the detector 24. Therefore, these antenna 21, amplifier 22, band-pass filter 23, detector 24
Etc. constitute the receiving means

When a signal from the portable telephone 27 is detected, the voice warning circuit pre-recorded by the voice synthesizing circuit 25 is reproduced and transmitted from the speaker 26. Therefore, the voice synthesizing circuit 25, the speaker 26, and the like constitute a notification unit. In addition to the warning by sound, a lamp display, an image display, and the like such as a lamp, a strobe light, a light emitting diode display, and a liquid crystal display can be used together, or a lamp display, an image display, and the like can be used alone without using sound.

When the apparatus shown in FIG. 1 is installed in a place where the use of the mobile phone 27 is prohibited, a guidance warning sound is reproduced from the speaker 26 at the same time as the telephone call of the mobile phone 27 starts, so that the user of the mobile phone 27 cannot use the apparatus. It is possible to notify directly by voice that the place is prohibited.

When a voice is transmitted from this apparatus, since the guidance voice itself disturbs others, it is not used in places where quietness is required, such as theaters, restaurants, and conference halls, and mainly mobile phones such as hospitals are used. It is very effective for use in places where malfunction of the machine becomes a problem due to electromagnetic waves.

For the contents of the voice in such a case, for example, "I would like a person using a mobile phone. Please refrain from using a mobile phone in a hospital because it may cause malfunction of medical equipment." And so on.

(Embodiment 2) FIG. 2 is a system configuration diagram of a mobile phone use prevention apparatus according to Embodiment 2 of the present invention. The detecting unit (receiving means) 61 shown in FIG. 1 is installed at a place where use of a mobile phone is to be prohibited. This detector 6

Here, the subscriber identification number is notified by a notification circuit (subscriber number transmission circuit) 47 to a mobile phone base station 62 whose service area is a place where the detection unit 61 is installed. The notification means may be a private line, a public line network such as ISDN, a dedicated line, a frame relay, a radio, or the like. Further, the receiving unit may notify the base station of the received encrypted subscriber identification number as it is, and the base station may decode the subscriber identification number.

In the mobile telephone base station 62, the ordinary exchange 5
0, an interrupt control device 49 is added to the transmission / reception device 51 including the antenna 52. The call to the other party with the subscriber identification number notified from the detection unit 61 is interrupted, and the mobile phone 56
In addition, it notifies the other party 63 of the mobile phone that the use of the mobile phone is prohibited by voice of the phone. Alternatively, when the subscriber identification number is detected, the ring tone for the mobile phone 56 is stopped, and the other party 63 is notified by voice of the phone that the other party is in a place where use of the mobile phone is prohibited. . Note that in FIG.
Reference numeral 5 denotes a mobile phone → base station control signal, and reference numeral 54 denotes a base station → mobile phone control signal.

An operation example is shown in FIGS. FIG. 3 shows an operation at the time of an incoming call. Upon receiving the call signal, the mobile phone transmits a call response signal and an authentication response signal. The detector receives the response signal and notifies the exchange of the base station of the subscriber identification number. The exchange that received the notification interrupts the ringing call, stops the ringing of the mobile phone,
The caller is notified by voice that the other party is in a place (in a specific area) where use of the mobile phone is prohibited.

FIG. 4 shows the operation at the time of transmission. The detection unit receives a call request signal and an authentication response signal transmitted from the mobile phone, and notifies the exchange of the base station of the subscriber identification number. The exchange that has received the notification notifies the user of the mobile phone by voice using the communication channel that the user is in a place where use is prohibited.

This embodiment is very effective when used in places where silence is required, such as theaters, movie theaters, restaurants, and conference halls, which cannot be used in the first embodiment.

By installing this device in a place where the use of a mobile phone is prohibited, it is possible to inform the user of the mobile phone directly that the use of the device is prohibited. Can be notified that they are in a place where the use of mobile phones is prohibited.

(Embodiment 3) FIG. 5 shows an example of device installation in a case where the area where use of a mobile phone is prohibited is large. If the area where mobile phone use is prohibited is large,
A plurality of antennas 65, receivers 66, and a signal processing unit 67 are provided so that the sensitivity of each receiver 66 is reduced instead of erroneously restricting outgoing / incoming calls from outside the area. I do. If the sensitivity of each receiver 66 is adjusted so as to respond only to a nearby mobile phone, it does not respond to outgoing / incoming calls from outside the area.

(Embodiment 4) FIG. 6 is a system configuration diagram of a mobile phone use prevention apparatus according to Embodiment 4 of the present invention. FIG. 7 shows a series of operations. From the pseudo base station signal generation circuit 73, a pseudo base station signal 83 similar to the base station signal is transmitted. It is assumed that the area identification code included in the pseudo base station signal 83 is different from the area identification code transmitted by the base station serving the place where the device is located. Upon receiving the pseudo base station signal, the mobile phone 82 detects a change in the area identification code and determines that the mobile phone has crossed the wireless zone.
A location registration request signal 84 including the subscriber identification number is transmitted.

The location registration request signal 84 is transmitted to the antenna 71
After being amplified by an amplifier 74, unnecessary signals are cut by a band-pass filter 75, input to a detector 76, and decoded by a decoder 77. When the position registration signal is received, the voice warning circuit reproduces the pre-recorded guidance warning voice from the voice synthesizing circuit 79 and sends it out from the speaker 80. In addition to the sound warning, a lamp, a strobe light, a light emitting diode display, a liquid crystal display, or the like may be used together, or a lamp display or the like may be used alone without using sound.

In addition to giving a voice notice directly from the speaker, the subscriber identification number is transmitted to the base station serving the place where the apparatus is located, and the call to the portable telephone 82 is suspended. Alternatively, the mobile phone 82 can be called to alert the mobile phone user by the voice of the phone.

Since this device causes the mobile phone to transmit the location registration signal, it is possible to detect the mobile phone not only during a call but also in a state where the power is turned on.

This device is installed near the entrance of a place where the use of a mobile phone is prohibited. If the user tries to bring in a mobile phone with the power on, the user is instructed to turn off the mobile phone, and it is possible to prevent the mobile phone from being brought in with the power on.
