DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone in a hospital, a movie theater or the like.
Including HS. The present invention relates to a mobile phone usage restriction processing system for restricting the use of a mobile phone.

[0002]

2. Description of the Related Art In recent years, portable telephones have become widespread and widely used as means for communicating and communicating on the move. However, since a mobile phone emits relatively strong electromagnetic waves, it is said that the mobile phone may have an adverse effect on electronic devices near the mobile phone. For this reason, in facilities such as hospitals, an announcement is made to turn off the power of the mobile phone to prevent various adverse effects.

[0003]

However, even if an announcement is made to turn off the mobile phone, the owner may not keep the power of the mobile phone turned off, or may inadvertently forget to turn off the power of the mobile phone. Therefore, it is not always the case that there is no adverse effect due to the radio wave of the mobile phone.

For this reason, in a facility such as an intensive care unit of a hospital, which is significantly affected by radio waves emitted from a mobile phone,
In some places, radio wave shields are installed at facilities to prevent radio waves from mobile phone base stations in the city from entering the facility. However, when a radio wave shield is installed, it is necessary to construct a stricter radio wave shield in a place near a mobile phone base station in the city because the radio wave of the mobile phone base station is strong. In such a place, there is a problem that it is necessary to construct an advanced radio shield corresponding to a shield room used in a laboratory on a large scale, so that a considerable cost is required.

[0005] Even when such a radio wave shield is installed, there is a case where the radio wave of the mobile phone base station cannot be completely shielded after the actual installation.

SUMMARY OF THE INVENTION The present invention provides a mobile phone use restriction processing system for limiting a mobile phone call without installing a radio wave shield as in the prior art.

[0007]

A portable telephone use restriction processing system according to the present invention is installed in a city in a building having a predetermined area for restricting use of a portable telephone. A picocell base station that sets the intensity of the radio wave to be transmitted is installed so that the radio wave of the control signal requesting the mobile phone to respond is stronger than the radio wave of the mobile phone base station. When the response signal is received, use restriction processing for restricting use of the mobile phone is performed. A picocell base station is a device that has functions similar to those of a mobile phone base station installed in the city and sends various control signals to a mobile phone.

As described in claim 2, claim 3 or claim 4, the use restriction process includes a process of turning off the power of the cellular phone that has received the response signal by the picocell base station, and a process of turning off the response signal by the picocell base station. Call the mobile phone that received the mobile phone, and process the voice information to request the mobile phone holder to turn off the mobile phone, and switch the power of the mobile phone to the mobile phone that received the response signal from the picocell base station. There is a process of displaying a message requesting to turn off.

According to a fifth aspect of the present invention, the picocell base station is connected to a central management station that manages a mobile phone base station installed in the city, and the use restriction processing is performed by the central management station. The base station may perform a process of restricting the use of the mobile phone that has received the response signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone use restriction processing system according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example in which a mobile phone use restriction processing system 10 according to the present invention is applied to a hospital 3 having an intensive care unit 2 for which use of a mobile phone 1 is prohibited.

The mobile phone use restriction processing system 10 is provided with a picocell base station 4 that emits a small-power radio wave in a hospital 3, and when the mobile phone 1 enters a jurisdiction of the picocell base station 4. The use of the mobile phone 1 is a process for restricting the use of the mobile phone 1, such as making the call of the mobile phone 1 interrupted. It was used.

By the way, the control method of the mobile phone 1 is shown in FIG.
As shown in FIG. 1, the location of the mobile phone 1 is managed by the mobile phone base stations 11a to 11c, which are installed in a large number of telephone companies in the city, and the mobile phone 1 is called. Each of the mobile phone base stations 11a to 11c is connected to the central control station 12, and has management areas A, B, and C to which the control signal s3 reaches.

When the mobile phone 1 enters the management area A of a certain mobile phone base station 11a, or when the management area of the mobile phone base station 11a
When the mobile phone 1 is turned on in A, the mobile phone 1 receives the control signal s3 of the mobile phone base station 11a and
Response signal with identification information
Send s2. The mobile phone base station 11a receives the response signal s2 of the mobile phone 1 and performs a location registration process of registering the presence of the mobile phone 1 in its own management area A with the central management station 12. When the location registration processing is completed, the mobile phone base station 11a sends a control signal to the mobile phone 1 to stop transmitting the response signal s2. As a result, the mobile phone 1 does not continue to output the response signal s2, thereby reducing the battery consumption of the mobile phone 1 and extending the standby time.

As shown by an arrow 13 in FIG. 2, when the mobile phone 1 moves from the management area A of the mobile phone base station 9a to the management area B of a different mobile phone base station 11b, the mobile phone 1 Recognizing that the strengths of the control signals s3 of the base stations 11a and 11b are reversed, a response signal s2 is transmitted at a location past the boundary between the management area A and the management area B of the mobile phone base station 11a. Then, the mobile phone base station 11b having the management area B receives the response signal s2 of the mobile phone 1 that has moved, and checks that the mobile phone 1 is present in its own management area B.
Perform the location registration process to register in. Thus, the location registration information of the mobile phone 1 in each of the mobile phone base stations 11a to 11c is:
Collected at the central management office 12. The central management station 12 transmits a calling signal and a communication signal of the mobile phone 1 from a predetermined mobile phone base station in which the location of the mobile phone 1 is registered based on the location registration information.

Hereinafter, a mobile phone use restriction processing system 10 will be described.
The picocell base station 4 used for will be described.

The picocell base station 4 is a device that has functions similar to those of a mobile phone base station installed in the city and sends various control signals to the mobile phone 1. The two-dot chain line 6 in FIG. 1 indicates the radio wave of the mobile phone base station 5 in the city, and the one-dot chain line 7 indicates the radio wave of the picocell base station. The height of the two-dot chain line 6 and the height of the one-dot chain line 7 indicate the strength of each radio wave.

Radio wave 6 for transmitting a control signal of mobile phone base station 5
As shown in FIG. 1, the distance becomes weaker as the distance from the mobile phone base station 5 increases, and part of the radio wave 6 is cut off by the walls of the building.

Picocell base station 4 installed in hospital 3
Is stronger than the radio wave 6 from the mobile phone base station 5 in the hospital 3 building, and part of the radio wave 7 is cut off by the building wall outside the hospital 3 building. Telephone base station 5
The strength of the transmitted radio wave 7 is set so that it is weaker than the radio wave 6. For example, the radio wave 7 of the picocell base station 4 is 5 dB to 10 dB higher than the radio wave 6 of the mobile phone base station 5 in the hospital 3.
The strength of the radio wave 7 to be transmitted is set so that it becomes stronger.

The control signal s1 transmitted from the picocell base station 4
Is a signal requesting a response from the mobile phone 1,
Is used to transmit the response signal s2 at least once, and the mobile phone 21 does not need to stop the operation of transmitting the response signal s2 properly like the mobile phone base station 5 in the city. This is because the control method by the picocell base station 4 may require the mobile phone 1 to keep outputting the response signal s2 when the holder of the mobile phone 1 does not turn off the power of the mobile phone 1.

Next, a control method by the picocell base station 4 will be described. Radio waves from mobile phone base stations 5 in the hospital 3
Since the radio wave 7 of the picocell base station 4 is stronger than 6, the mobile phone 1 recognizes that the mobile phone 1 has entered the management area of a different mobile phone base station, and responds to the control signal s 1 of the picocell base station 4 Send s2.

The picocell base station 4 receives a response signal from the mobile phone 1.
When s2 is received, use restriction processing set in advance to turn off the power of the mobile phone 1 is performed.

The use restriction processing includes, for example, the following processing. Call the mobile phone 1 and when the owner answers the phone, "Because it is in a hospital, please turn off the mobile phone."
And sound information. Call up the mobile phone 1 and use the mobile phone 1's e-mail receiving function to display a message on the mobile phone 1 saying "Because it is in a hospital, please turn off the mobile phone." When you call the mobile phone 1 and the owner answers the phone, you will hear the voice message saying "Because it is in a hospital, the mobile phone will be turned off." Send special control signals.

While the above processing is a means for requesting the holder to turn off the mobile phone, the processing is a means for forcibly turning off the mobile phone. This is considered to be an effective process as a final measure in public facilities such as Also, in order not to confuse the owner with the failure of the mobile phone 1, instead of forcibly turning off the power of the mobile phone 1 suddenly, for example, the owner may turn off the mobile phone 1. If the owner does not turn off the power of the mobile phone 1 after performing the request or the processing of the picocell base station, the response signal s2 is continuously output from the mobile phone 1.
When captured in step 4, it may be desirable to perform the following processing.

The picocell base station 4 may be connected to a central management station 8 of a mobile phone company as shown in FIG.
It may be a unique facility in the hospital 3 independent of the central control station 8.

When the picocell base station 4 is connected to the central control station of the mobile phone company, when the picocell base station 4 receives the response signal s2 of the mobile phone 1 (in other words, when the mobile phone 1 The central management station 8 may cooperate with the mobile phone company to perform a process of interrupting the mobile phone 1 (the same process as when the mobile phone 1 is out of the service area).

According to this processing, the picocell base station 4 is arranged in, for example, a movie theater or a theater by the management of the mobile phone company, and when the location registration processing is performed by the picocell base station 4, the mobile phone 1 is disconnected. Can be performed, and the ringing tone of the mobile phone can be prevented from being generated in the hall. Further, it is also possible to perform use restriction processing with time limitation, such as restricting the use of the mobile phone only during various performances in movie theaters and theaters.

In this case, there is no need for the holder to turn off the power of the mobile phone 1, and when the holder leaves the movie theater and enters the management area of the mobile phone base station 5 in the city, the mobile phone in the city is Since the telephone base station 5 receives the response signal s2 of the mobile phone 1 and performs the location registration process, the mobile phone 1 can be called as usual.

Although the mobile phone restriction system 10 according to one embodiment of the present invention has been described above, the present invention is not limited to the above.

The facility where the picocell base station is installed is not limited to a hospital, but is applicable to places such as movie theaters, theaters, airplanes, and trains where the radio wave of the picocell base station can be stronger than that of a mobile phone base station in the city.

[0031]

The system for restricting use of a mobile phone according to the present invention can be used in a building having a predetermined area for restricting the use of a mobile phone, rather than a mobile phone base station installed in a city. Install a picocell base station that sets the strength of the radio wave to be transmitted so that the radio wave of the control signal for asking the telephone is strong, and when this picocell base station receives the response signal of the mobile phone, Since the use restriction process for restricting the use is performed, it is not necessary to construct a radio wave shield as in the related art, and the use of the mobile phone can be restricted at low cost.

As described in the second aspect, the use restriction process is a process of turning off the power of the mobile phone that has received the response signal from the picocell base station, so that the use of the mobile phone is surely performed irrespective of the owner's intention. Can be restricted.

According to a third aspect of the present invention, the picocell base station calls the mobile phone which has received the response signal and transmits voice information to request the mobile phone holder to turn off the power of the mobile phone. With the flow processing, a warning to the effect that the power of the mobile phone is turned off can be reliably transmitted to the mobile phone holder, and the use of the mobile phone can be suppressed.

According to a fourth aspect of the present invention, the use restriction process is a process of displaying a message requesting that the power of the mobile phone be turned off on the mobile phone having received the response signal from the picocell base station. The device can surely transmit a warning to the effect that the power of the mobile phone is turned off to the owner of the mobile phone, and can suppress the use of the mobile phone.
As described in, the picocell base station was connected to the central management station that manages the mobile phone base station installed in the city, and the picocell base station received a response signal by the management of the central management station in the use restriction process. In the processing for restricting the use of the mobile phone, in cooperation with the mobile phone company, for example, the picocell base station can use a process of restricting the call of the mobile phone that has received the response signal, such as a call interruption.
