  Furthermore, the mobile communication device according to the present invention includes a receiving means for receiving an operation restriction signal indicating an operation restriction time from the operation restriction device, and an operation indicated by the operation restriction signal when the operation restriction signal is received. Operation limiting means for limiting the operation of the mobile communication device based on the time limit.

  According to the present invention, the operation restriction time is indicated by the operation restriction signal received from the operation restriction device, and the operation of the mobile communication device is restricted based on the operation restriction time. For this reason, operation | movement of a mobile communication apparatus can be restrict | limited continuously over operation | movement time limit, for example.

  In one aspect of the present invention, the operation restriction means restricts radio wave radiation from the mobile communication device. If it carries out like this, the electromagnetic wave radiation by a mobile communication apparatus can be restrict | limited as needed.

  Further, the operation restriction means may stop the voice communication being continued by the mobile communication device according to a predetermined procedure.

  In the aspect of the invention, the transmission unit transmits the operation restriction signal by infrared rays. Infrared communication is short-range communication, and is suitable for keeping the transmission range of the operation restriction signal within a certain range.

  In the aspect of the invention, the operation restriction device is installed at least at the entrance of a facility where the operation of the mobile communication device should be restricted. In this way, the operation of the mobile communication device can be surely restricted at the entrance of the facility.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a configuration diagram of a mobile communication system according to an embodiment of the present invention. As shown in the figure, this mobile communication system includes a mobile phone (mobile communication device) 10 for performing voice communication, and an operation restriction device 16 for restricting the operation of the mobile phone 10. Has been. When the mobile phone 10 is located within the service area 14 of the base station 12, the mobile phone 10 can perform voice communication with other mobile phones and fixed phones by relaying the base station 12. An operation restricting device 16 is set at the entrance 18a of the facility 18 where the operation of the mobile phone 10 such as a movie theater, a museum, a hospital, a train, a bus, an airplane, etc., for example, the emission of radio waves should be restricted. When entering the facility 18 from the entrance 18a with 10, the operation restriction device 16 stops the operation of the mobile phone 10.

  The operation limiting device 16 includes an infrared light emitting unit 16a and a control unit 16b. The control unit 16b converts the operation limiting signal having the configuration shown in FIG. 2 into an infrared light signal as an infrared signal at predetermined time intervals. Is sending from. That is, the operation restriction signal transmitted from the operation restriction device 16 includes data of a specific code indicating that the operation is restricted and data indicating the operation restriction time following the code. The intensity of the infrared signal is adjusted to a level at which the infrared signal is transmitted even in the winter clothes of the user of the mobile phone 10.

  On the other hand, as shown in FIG. 3, the mobile phone 10 includes a transmission / reception unit 10a, a control unit 10b, an infrared communication unit 10c, an antenna 10d, and an infrared light receiving unit (infrared sensor) 10e. The transmission / reception unit 10a includes a transmission / reception high-frequency circuit and a digital circuit. The transmission / reception unit 10a demodulates an audio signal from a radio wave received by the antenna 10d, and outputs sound through a speaker (not shown). In addition, sound input from a microphone (not shown) is transmitted by the antenna 10d.

  The infrared communication unit 10c receives an infrared signal by the infrared light receiving unit 10e. Here, the infrared communication unit 10c receives an operation restriction signal transmitted from the operation restriction device 16, and passes the contents to the control unit 10b. In the control unit 10b, the operation restriction signal is not transmitted at regular intervals, that is, the operation restriction device 16 is set in the vicinity, and the operation restriction signal transmitted from the operation restriction device 16 is not received. Is determined by the infrared communication unit 10c. If the operation restriction signal is received, the operation of the transmission / reception unit 10a is stopped and the voice communication via the base station 12 is stopped. Thereby, transmission / reception of the electric wave by the antenna 10d is stopped. At this time, the operation restriction signal transmitted from the operation restriction device 16 includes the data indicating the operation restriction time as described above. In the control unit 10b, only the operation restriction time indicated by this data is transmitted from the transmission / reception unit 10a. The operation is stopped. Thereby, it is possible to reliably stop the operation of the mobile communication device 10 for a desired time. This operation restriction time is the movie performance time if the facility 18 where the operation restriction device 16 is installed is a movie theater, the average viewing time if it is a museum, the average use time if it is a hospital, train / bus Then, it is desirable to determine in advance based on the average boarding time, and in the case of an aircraft, based on the flight time, and store it in the control unit 16b.

  Here, the operation restriction process by the mobile communication device 10 will be described. FIG. 4 is a flowchart showing an operation restriction process performed by the control unit 10b of the mobile communication device 10. As shown in the figure, in the control unit 10b, first, the infrared communication unit 10c determines whether or not an operation restriction signal is received by the infrared light receiving unit 10e (S101). If an operation restriction signal has not been received, this determination is repeated at regular intervals. When the operation restriction signal is received, it is next determined whether or not voice communication is being performed by the transmitting / receiving unit 10a of the mobile communication device 10 (S102). If voice communication is being performed, the voice communication is stopped according to a predetermined procedure. That is, a message indicating that voice communication is about to be stopped is output from the speaker or display (LCD or the like) of the mobile communication device 10 (S103), and then the voice communication is stopped by the transmission / reception unit 10a. If the voice communication is not in progress, S103 and S104 are skipped.

  Next, the operation restriction time indicated by the operation restriction signal confirmed to be received in S101 is acquired (S105). And the electric power supply with respect to the transmission / reception part 10a is stopped, and the operation | movement is stopped. As a result, transmission / reception of radio waves by the antenna 10d is stopped. At the same time, a timer for monitoring the passage of the operation time limit is started (S106). Note that a message indicating that the operation is being restricted may be displayed on the display of the mobile communication device 10.

  Thereafter, the operation of the transmission / reception unit 10a is kept stopped until the operation time limit elapses (S107). If the operation limit time has elapsed, the power supply to the transmission / reception unit 10a is resumed and the operation is started again (S108). Thereafter, the reception of the operation restriction signal is monitored again (S101).

  According to the mobile communication system 10 described above, an operation restriction signal indicating an operation restriction time is transmitted from the operation restriction device 16 installed at the entrance 18a of the facility 18, and the mobile communication device that has received this operation restriction signal. Ten operations are stopped for the operation time limit. For this reason, it is possible to reliably stop the operation of the mobile communication device 10 for the time required on the facility 18 side.

  In addition, this invention is not limited to the said embodiment, For example, you may arrange | position the several operation | movement limitation apparatus 16 not only in the entrance 18a of the plant | facility 18 but in the plant | facility 18, for example with a suitable distance space | interval. Further, when the operation restriction device 16 is connected to the network side via the base station 12, for example, when there is an incoming call to the mobile communication device 10 whose operation is restricted, that fact is acquired, The mobile communication device 10 may be notified by a signal. In addition, a device that transmits an infrared signal for forcibly resuming the operation of the mobile communication device 10 is installed outside the facility 18, for example, at a ticket gate of a station, and the mobile communication device 10 receives this signal. In such a case, the operation of the transmission / reception unit 10a may be exceptionally resumed even within the operation time limit.
