[0002]
[Prior art]
In recent years, mobile communication devices such as mobile phones have rapidly spread due to the convenience of being able to communicate regardless of time and place by using them, and the usage forms have also diversified accordingly. ing.
On the other hand, there are many diversified usage patterns that are regarded as social problems. For example, the use of mobile phones while driving a car is pointed out as a factor causing traffic accidents. Has been.
[0003]
The use of a mobile phone while driving a car is dangerous as it reduces the driver's ability to concentrate on driving under any usage conditions. Higher than below.
That is, when a mobile phone holder (hereinafter referred to as a user) gets into a car to drive and makes a call using the mobile phone, the driver himself / herself determines that it is safe, for example, parking In contrast to calling when you are stopped at the parking lot, in the case of an incoming call, even if you are extremely careful about driving, such as when driving at an intersection, the call is started without choosing the situation . And, the driver responds reflexively to the incoming call, and at this time, not only the consciousness but also the line of sight and hands are directed toward the mobile phone, so the driving ability is extremely lowered and it is easy to cause an accident. The problem of becoming is pointed out.
[0004]
Therefore, as a means to prevent the occurrence of such an accident, when a user drives a car, the user turns off the power of the mobile phone or, for example, an automatic answering or answering machine provided by a mobile phone carrier Or it is common to set beforehand the reception function of a mobile telephone using various service functions, such as a transfer telephone.
The restriction of the reception function is to suppress at least the call operation of the mobile communication device due to an incoming call. For example, when using the service function described above, the mobile communication device generates a ringing tone or the like even if there is an incoming call. First, when the user cancels the setting and returns to the normal mode, the mobile phone display unit informs that there is an incoming call.

However, the above-described conventional mobile communication device has the following problems. In other words, when turning off the power or using the service function, it operates by performing a setting operation such as pressing a specific function key of the mobile communication device. Since it is troublesome to execute the setting operation, there is a problem that it is not always utilized effectively because it may be neglected or may be forgotten to set it.
In addition, when canceling the setting, the same operation must be performed, and the actual situation is that the desire to actively use this service function is reduced.
[0007]
Also, when radiating jamming radio waves, the entire interior of the car becomes a prohibited area, and not only the driver's mobile communication device but also the passenger's mobile communication device is paralyzed. It will be.
[0008]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
FIG. 1 is a diagram showing an embodiment of a locking device for a mobile communication device according to the present invention.
[0011]
The locking device for a mobile communication device shown in this example includes an interference radio wave generating unit 5 and a locking device 4 for detachably holding a mobile communication device 3 having a transmission / reception antenna 1 and a display unit 2. , The transmitting antenna 10 is provided, and power is supplied from the power source 11 to the jamming wave generator 5. For example, if the locking device 4 is fixedly arranged in an automobile, an automobile battery can be used as the power source 11.
The interference radio wave generator 5 includes a local oscillator 6, a pseudo noise generator 7 that generates artificial pseudo noise in a certain frequency band based on an output from the local oscillator 6, and the pseudo noise generator 7. A band filter 8 that passes only a desired frequency band from the output of, and an amplifier 9 that amplifies the output from the band filter 8 and outputs the amplified signal to the transmitting antenna 10.
The band filter 8 corresponds to the reception frequency band of the mobile communication device 3, and for example, each reception in the 800 MHz band and the 1.5 GHz band in order to correspond to various mobile communication devices 3 having different methods. A plurality of filters for filtering the band and a synthesizer for synthesizing the filtered signals are provided.
[0012]
The mobile communication device locking device shown in this figure functions as follows. That is, the mobile communication device 3 constantly monitors a call signal from a base station of a mobile communication system (not shown) in a standby state. At this time, the reception level of the paging signal received by the mobile communication device 3 is a very small level of about several dBμ, and the mobile communication device 3 is required to demodulate information from the received radio wave without error. An N ratio (signal to noise ratio) of 40 dB or more is required.
[0013]
On the other hand, the latching tool 4 radiates the jamming radio wave generated by the built-in jamming radio wave generator 5 from the transmission antenna 10, and the transmission level of the jamming radio wave is held by the latching tool 4 by the mobile communication device 3. In this state, the mobile communication device 3 is about several dBμ equivalent to the reception level at which the paging signal is received. If the mobile communication device 3 is removed from the locking device 4 and separated by several tens of centimeters, the influence of the jamming radio wave is reduced, and the S / N ratio necessary for demodulating the calling signal can be received. Yes.
[0014]
In other words, since the locking tool 4 is a target for obstructing the mobile communication device 3 to be held, the electric field strength of the jamming radio wave is concentrated on the place (direction) where the mobile communication device 3 is held, and the others The location (direction) is configured not to radiate jamming radio waves. Specifically, the transmitting antenna 10 is directed so as to radiate to the place (direction) where the mobile communication device 3 is held, and to prevent the jamming radio wave from leaking to other places (directions). What is necessary is just to comprise using what has shielding effects, such as a radio wave absorber and a radio wave reflector, in the outer peripheral member of the tool 4.
[0015]
Further, the interference radio wave deteriorates the reception S / N ratio of the mobile communication device 3 when the mobile communication device 3 is held by the locking device 4, and the pseudo noise in the interference wave is Each spectrum is intentionally distorted by actively changing the level and phase.
[0016]
In other words, the mobile communication device locking device according to the present invention places the mobile communication device 3 on the locking device 4 when the user gets on the vehicle to drive the mobile communication device. The reception function is restricted so that the ringing tone does not sound even when there is an incoming call so that the radio wave reception of the machine 3 is obstructed and cannot be received (detected).
[0017]
As a result, as long as the user places the mobile communication device 3 in a predetermined place (locking tool 4) without performing complicated key operations, the incoming call will not be made and the user will concentrate on driving. It is possible to secure safety while driving a car related to a user's mobile communication device.
[0018]
Next, another embodiment of the locking device for a mobile communication device according to the present invention will be described with reference to FIGS. In addition, about the functional part similar to FIG. 1 mentioned above, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
[0019]
FIG. 2 is a diagram showing a second embodiment of a locking device for a mobile communication device according to the present invention. A switch section 12 is added to the locking device 4 to hold / not hold the mobile communication device 3. An example in which holding is detected and the jamming wave generator 5 is driven will be described.
The locking device 4 in this figure is provided with a push-type switch 12 on the surface holding the mobile communication device 3. This switch 12 is connected so that the power supply line from the power source 11 to the jamming wave generator 5 can be opened and closed, and the switch 12 moves when the mobile communication device 3 is held by the locking device 4. The power supply line is closed when pressed by the weight of the body communication device 3. Thereby, the reception function of the mobile communication device 3 can be easily restricted by the same procedure as that shown in FIG. 1, and the locking device 4 holds the mobile communication device 3. When the mobile communication device 3 is held, the jamming radio wave can be radiated only when the mobile communication device 3 is held, and unnecessary radio wave radiation can be suppressed. It is also possible to suppress the consumption of the battery as a power source.
[0020]
Next, FIG. 3 is a diagram showing a third embodiment of the locking device for mobile communication devices according to the present invention. FIG. 3 shows a receiving antenna 13, a radio wave detector 14, a timer 15 in FIG. In the example, the mobile communication device 3 automatically responds to the base station when an incoming call is received and detects the radio wave transmitted and radiates the jamming radio wave.
The locking device 4 shown in this figure includes a switch unit 12 that is connected so as to be able to open and close a power supply line from the power source 11 to the jamming wave generating unit 5, a receiving antenna 13 that receives radio waves from the mobile communication device 3, and And a radio wave detector 14 for detecting radio waves received by the receiving antenna 13 and a timer 15 for measuring an arbitrary fixed time from when the radio wave detector 14 detects radio waves.
[0021]
The mobile communication device locking device shown in this figure functions as follows. That is, it is assumed that the mobile communication device 3 is detachably held by the locking tool 4 and the mobile communication device 3 is in a standby state. At this time, the switch unit 12 is open, the jamming signal generator 5 is not operating, and no jamming signal is radiated from the transmitting antenna 10. That is, the reception function of the mobile communication device 3 works normally.
[0022]
When the mobile communication device 3 detects its own number in the call signal from the base station that is constantly monitored in the standby state, the mobile communication device 3 automatically notifies the base station that the radio wave (call signal) has been received. It is supposed to emit radio waves. If the mobile communication device 3 is within the area of the base station, communication such as radio wave level and channel setting is performed between the mobile communication device 3 and the base station, and a certain line connection preparation is made. After that, the mobile communication device 3 sounds a ringing tone.
[0023]
Thus, when the radio wave emitted from the mobile communication device 3 is detected by the radio wave detection unit 14 via the receiving antenna 13, the locking device 4 immediately starts the timer 15, and the switch 4 based on the output from the timer 15. The unit 12 is operated to close the power supply line, and the jamming radio wave generation unit 5 is activated to radiate jamming radio waves from the transmitting antenna 10. Further, when a predetermined time set in advance in the timer 15 is measured, the switch unit 12 cuts off the power supply line accordingly, and the radiation of the jamming radio wave is stopped.
[0024]
The radio wave detection unit 14 detects the transmission frequency band of the mobile communication device 3, but does not react to the radio wave of several dBμ level due to the interference radio wave from the transmission antenna 10, and the mobile communication device 3. Since the sensitivity is set so as to react to a radio wave of several dBm level due to the radio wave from the transmission / reception antenna 1, it is prevented from operating by detecting the jamming radio wave emitted by the locking device 4 itself.
[0025]
That is, when the mobile communication device 3 automatically emits a radio wave in response to an incoming call, the locking device 4 immediately radiates the jamming radio wave and interferes with the reception of the mobile communication device 3. The communication for the line connection preparation performed between the mobile station and the base station is not successful, and the mobile communication device 3 does not reach the ringing tone and the reception function is limited.
As a result, the reception function of the mobile communication device 3 can be easily restricted. Further, the locking device 4 is capable of receiving radio waves even when the mobile communication device 3 is held. Until it is released, it does not radiate jamming radio waves, and it can radiate jamming radio waves for a certain period of time after the mobile communication device 3 emits radio waves, thereby suppressing unnecessary radio wave emissions. it can.
[0026]
Furthermore, if the radio wave detection unit 14 reacts only to a signal transmitted when the mobile communication device 3 responds to a call signal from the base station and generates a jamming radio wave, the adjacent base station area in the standby state Even if the mobile communication device 3 performs communication for authentication (referred to as a location registration function) between the mobile communication device 3 and the new base station, no disturbing radio waves are generated. This can be realized, for example, by providing a demodulation unit in the radio wave detection unit 14. Thus, it is possible to make a call with the mobile communication device 3 taken out from the locking device 4 immediately after moving for a long time in the automobile.
[0027]
Next, FIG. 4 is a diagram showing a fourth embodiment of the locking device for mobile communication devices according to the present invention, and FIG. 5 is a diagram of the present invention based on the fourth embodiment shown in FIG. It is a figure which shows the example of an external appearance of the locking tool for mobile communication apparatuses concerning.
The mobile communication device locking device shown in FIG. 5 has a structure in which openings of two box-shaped members configured using a shield member are overlapped so as to be openable and closable. It becomes the shield container comprised so that the whole may be covered. The sealed space that holds the mobile communication device 3 is referred to as a shield space 16. The transmitting antenna 10 of the locking device 4 is provided so as to radiate jamming radio waves only in the shield space 16.
[0028]
As the shield member, a conductor (metal or alloy such as copper or aluminum), or a plate, paint, powder, processed with a conductor and a dielectric (synthetic resin, glass, mica, etc.) Alternatively, there are various types such as a film-like sheet, and any shield member may be used as long as the shield space 16 can be formed. For example, the shield space 16 may be realized by tensioning a thin aluminum plate meshed on the inner wall surface of the resin stopper 4.
The shield space 16 attenuates radio waves in the reception frequency band from the base station to the mobile communication device 3 and interference radio waves radiated from the transmission antenna 10 of the locking device 4 by the shield member. .
In general, when the shield member is grounded (grounded), electric energy and thermal energy induced in the shield member by radio waves can be efficiently released, and the shielding effect is improved. Is used as a power source 11, and the shield member is grounded to the automobile frame.
The switch unit 12 is the same as that shown in FIG.
[0029]
In the mobile communication device locking device shown in this figure, since the mobile communication device 3 is held in the shield space 16 by the locking device 4, radio waves such as calling signals from the base station are not received. It is in a bad state and is in a state where reception is blocked by jamming radio waves. Therefore, the reception function can be more completely restricted, and the interference radio wave hardly leaks out of the locking device 4, so that the reception function of another person's mobile communication device riding in the automobile is not restricted. Can be.
[0030]
In the second to fourth embodiments of the present invention described above, an example in which the switch unit 12 is provided so as to open and close the power supply line has been described. For example, if the switch unit 12 is provided at the connection portion between the jamming wave generating unit 5 and the transmission antenna 10 and the power source is always supplied to the jamming wave generating unit 5, the jamming radio wave can be radiated / stopped with good response. Can be done.
[0031]
As described above, the locking device for a mobile communication device according to the present invention has only to hold the mobile communication device 3 on the locking device 4 provided in the vehicle when the user drives the vehicle. In other words, simply by placing, leaning on, or closing the lid, the reception function restriction of the mobile communication device 3 is easily set, and conversely, if the user removes the hold, the mobile communication can be easily performed. The reception function restriction of the machine 3 is released.
Further, the reception function restriction may be released when the vehicle is stopped by being linked with an engine of an automobile or a side brake.
Therefore, the reception function is appropriately restricted without the user's intentional key operation, etc., and the user's ability to concentrate while driving is not obstructed, thus ensuring a safe driving environment. Can do.
[0032]
【The invention's effect】
As described above, the locking device for a mobile communication device according to the present invention provides a locking place for the mobile communication device in an environment inappropriate for using the mobile communication device, and the user can As long as the mobile communication device is locked (held) at the stop location, the specified reception function is surely restricted, so that the user does not need to consciously perform troublesome setting operations, and the mobile body The manners related to the use of communication equipment can be protected.
