BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The communication restriction system according to the present embodiment is for restricting the use of a mobile communication terminal such as a mobile phone having a communication function via a wireless telephone line, and includes a restriction signal transmission terminal installed in a restriction area. And a terminal-side device built in the regulated mobile communication terminal. Among these, the restriction signal transmitting terminal transmits a predetermined restriction signal including information indicating the priority of restriction on the use of the mobile communication terminal to an area where the use of the mobile communication terminal is to be restricted, and It is configured to be portable. Further, the terminal device incorporated in the mobile communication terminal has a function of receiving the above-mentioned restriction signal and analyzing the restriction information (signal receiving means), and a function of calculating the degree of restriction based on this information (degree calculation). Means) and a function (processing executing means) for executing processing for restricting the function of the portable communication terminal according to the degree of the regulation.
[0010]
In this communication regulation system, a specific regulation signal is transmitted from a small and inexpensive regulation signal transmission terminal, and a mobile communication terminal that receives the signal performs predetermined arithmetic processing based on the regulation signal to determine a regulation to be received by itself. The degree is calculated, and the function is restricted according to the degree. The restriction signal transmitted by the restriction signal transmitting terminal includes information indicating the priority of restriction on the use of the mobile communication terminal (hereinafter, referred to as “restriction priority”). The function of the communication terminal is restricted. In the present embodiment, it is assumed that the regulation priority can take a value from "0" to "5", and a value "1" has the lowest regulation priority, and hereinafter, a value from "2" to "5" increases in order from "2" to "5". And In addition, a value “0” indicates that regulation is released. Since the restriction signal transmitting terminal is portable, a plurality of restriction signals may be present when a plurality of users of the restriction signal transmitting terminal are at a short distance from each other.
[0011]
FIG. 1 shows a relationship between a plurality of restriction signal transmitting terminals R1, R3, R5 and restriction areas E1, E3, E5 according to the present embodiment. This example shows a case where three regulation signal transmission terminals R1, R3, and R5 exist at a relatively short distance. In the figure, a restriction signal transmitting terminal R1 transmits a restriction signal having a restriction priority of "1", and the reach of the restriction signal is defined as a restriction area E1. The restriction signal transmission terminal R3 transmits a restriction signal having a restriction priority of “3”, and sets the reach of the restriction signal as a restriction area E3. Further, the restriction signal transmission terminal R5 transmits a restriction signal having a restriction priority of “5”, and sets the reach of the restriction signal to a restriction area E5. In this example, since the restriction signal transmitting terminals R1, R3, and R5 are located at a short distance from each other, the restriction areas E1, E3, and E5 created by the terminals overlap each other. Since the total value of the regulation priority is “9” in the area where the overlap has occurred, it can be said that the requirement for regulation is large. Therefore, in this communication regulation system, the area where the overlap occurs is treated as an area having a regulation priority higher than the regulation priority indicated by the regulation signal transmitted by each regulation signal transmission terminal alone. It is possible to change the range of the restricted area by adjusting the output of the restricted signal transmitting terminal within a range that does not affect medical equipment and the like.
[0012]
FIG. 2A shows a configuration example of information included in each restriction signal transmitted by the restriction signal transmission terminals R1, R3, and R5. In this example, the restriction signal includes a restriction signal transmission terminal ID representing the restriction signal transmission terminal that is the transmission source of the restriction signal, and information on the above-described restriction priority P requested by the restriction signal transmission terminal itself. The restriction signal transmission terminal ID is used to identify the restriction signal transmission terminal to the mobile communication terminal. Each restriction signal transmitting terminal transmits a restriction signal including the above information at intermittent and random time intervals. That is, after transmitting the restriction signal at random timing for a certain period of time, the transmission of the restriction signal is stopped, and then the restriction signal is transmitted again. FIG. 2B shows an example of a storage form of information included in the regulation signal received by the mobile communication terminal. In this example, the regulation signal transmitting terminal ID, the regulation priority P of the regulation signal, and the number of times the regulation signal is received are stored in the storage unit in the portable communication terminal for each regulation signal.
[0013]
Next, an operation (a communication restriction method) of the present embodiment will be described.
First, the overall operation will be described. The mobile communication terminal monitors the regulation signal arriving at the mobile communication terminal in units of a certain fixed time. Since the restriction signal is transmitted at random time intervals as described above, a case where a plurality of restriction signal transmitting terminals simultaneously transmit the restriction signal may occur. In this case, the mobile communication terminal may not be able to accurately receive the restriction signal from each of the restriction signal transmission terminals, but by monitoring the restriction signal for a certain period of time, the mobile communication terminal may perform multiple times for each of the plurality of restriction signals. , And receives each regulation signal on average. After a certain period of time, the mobile communication terminal calculates the degree of restriction to be received by the mobile communication terminal from the number of receptions of the received restriction signal, and limits the function of the mobile communication terminal according to the calculation result.
[0014]
Hereinafter, the operation will be described in detail.
FIG. 3 and FIG. 4 are flowcharts showing an example of the flow of processing on the side of the portable communication terminal that constitutes the communication restriction system. Here, the description will focus on the regulation signal transmitting terminal R1 shown in FIG.
First, the user of the restriction signal transmitting terminal R1 who wants to restrict the use of the mobile communication terminal sets the value of the restriction priority P according to the desired degree of restriction and the size (range) of the restricted area to the restriction signal transmitting terminal R1. Set to R1. The restriction signal transmitting terminal R1 in which the restriction priority P is set transmits a predetermined restriction signal including information relating to restriction such as the restriction signal transmission terminal ID and the restriction priority P with an output corresponding to the size of the restriction area ( Send.
[0015]
On the other hand, in the portable communication terminal A to be regulated, the following series of regulation control is executed. That is, a timer T1 for measuring a period for monitoring a regulation signal is started (step S1), an incoming regulation signal is monitored, and it is determined at any time whether or not a regulation signal has been received (step S2). When the portable communication terminal A receives the regulation signal (Step S2; Y), it analyzes the regulation signal transmitting terminal ID and the regulation priority P included in the regulation signal (Step S3). Then, it is determined whether or not the information can be analyzed, that is, whether or not the result of analyzing the information is normal (step S4). Here, for example, when the above-mentioned restriction signal transmission terminal ID is not set and each of the restriction signal transmission terminals does not have its own restriction signal, the mobile communication terminal simultaneously transmits a plurality of restriction signals. When receiving the information, there is a possibility that the information may not be correctly analyzed. Therefore, in step S4, the control signal that cannot be correctly analyzed is ignored.
[0016]
Subsequently, it is determined whether or not the restriction signal transmitting terminal ID analyzed in step S3 already exists in the storage unit (step S5). If the restriction signal transmission terminal ID already exists in the storage unit (step S5; Y), the value of the restriction priority P corresponding to the restriction signal transmission terminal ID is updated (step S6). Note that this update process takes into account the case where the user of the regulation signal transmitting terminal changes the set value of the regulation priority P. However, if the configuration is to be simplified, this process is omitted. Is also good. If the restriction signal transmission terminal ID does not exist in the storage unit (step S5; N), the restriction signal transmission terminal ID indicating the transmission source of the restriction signal and the restriction priority P are newly stored (step S7). Then, "1" is added to the total number of received regulation signals (step S8). Subsequently, “1” is added to the number of times the received regulation signal of the regulation signal transmitting terminal ID is received (step S9), and it is determined whether or not the total number of received regulation signals is equal to or more than a certain value (step S10). Here, the “constant value” is an upper limit value of the number of information of the regulation signal that can be stored in the storage unit in the mobile communication terminal, and the storage value of the mobile communication terminal is set by setting an appropriate value according to the device configuration. This prevents inconveniences such as pressing the part more than necessary.
[0017]
Subsequently, it is determined whether the timer T1 has elapsed for a predetermined time (step S11). If it has elapsed, the timer T1 is cleared (step S12), and if not, the process returns to step S2. Then, among the stored regulation signals, the information of the signal whose reception count is 0 is deleted (step S13). This means that, after clearing the number of receptions in step S23 to be described later, the fact that no regulation signal has been received at all means that the mobile communication terminal does not already exist in the regulation area based on the regulation signal. Because. Subsequently, in the present example, of the restriction signals stored in the storage unit, a predetermined calculation is performed on the restriction priority P represented by the restriction signal having a value of the number of receptions less than a certain value, and the value of the restriction priority is adjusted. (Step S14). For example, a restriction signal with a small number of receptions reduces the restriction priority P according to the number of receptions. This restricts mobile communication terminals to excessive control just by passing near the control signal transmitting terminal, or to mobile communication terminals that are near the boundary of the control area but do not stay in the control area for a long time. Is avoided.
[0018]
Subsequently, based on the regulation priority P stored in the storage unit, a regulation value indicating the degree of regulation that the mobile communication terminal A should receive is calculated. Specifically, the control unit 20 totals the control priorities P of the control signals stored in the storage unit, and sets the sum as a control value (step S15). Here, it is possible that an appropriate regulation value may not be obtained by simply adding the regulation priority P, that is, in consideration of a case where regulation is excessive or does not conform to the actual situation, for example, If there is only one restriction signal having the same restriction priority P, the restriction priority P is left as it is. If there are a plurality of restriction signals, the restriction priority P is set according to the number of times of reception of the restriction signal corresponding to each restriction signal transmission terminal ID. In this case, the control priority P may be calculated and the total value thereof may be used as the control value. The regulation value corresponding to the number of receptions can be obtained by subjecting the regulation priority P to an arithmetic processing of the following equation (1), and the value PS obtained as a result of this computation can be newly set as the regulation priority P. In the equation (1), “n” is the number of times the restriction signal indicating the restriction priority P is received, and “α” is a constant.
[0019]
PS = α × P × logn (1)
[0020]
Subsequently, the control value obtained in step S15 is compared with the control value calculated last time (step S16). If this value is the same as the previous regulation value (step S16; Y), the current limitation on the function of the portable communication terminal is not changed and the current limitation is continued. On the other hand, if the values are not the same (step S16; N), the contents of the restriction are determined according to the restriction value (step S17), and processing for restricting the function of the mobile communication terminal is executed (steps S18 to S18). S21). If the regulation value is "0", a process for removing the regulation (restriction release process) is executed (step S18).
[0021]
When the regulation value is “1” to “5”,..., “N”, the function for restricting each function such as the call function and the data communication function of the portable communication terminal is set according to each value. Restriction processing is performed (steps S19 to S21). Subsequently, the calculated regulation value is stored in the storage unit as a previous regulation value, and the previous regulation value stored in the storage unit is updated (step S22). Thereafter, the number of times of reception of the restriction signal stored in the storage unit is cleared, the number of receptions is returned to 0 (step S23), and the total number of received restriction signals is returned to 0 (step S24). Then, a timer T2 for measuring the time during which the regulation should be actually maintained is started (step S25). Finally, when a certain time has elapsed, the timer T2 is cleared (step S27), and the process returns to the above-described step S1. Thereafter, the same processing is repeatedly performed. The operation (the communication restriction method) of the present embodiment has been described above.
[0022]
Next, an application example of the communication regulation system according to the present embodiment will be described. FIG. 5 shows an application example of the present communication regulation system. In the example illustrated in FIG. 5A, another passenger having the restriction signal transmission terminal R1 having the restriction priority “1” exists near the portable communication terminal A of the passenger of the train vehicle 202, and the adjacent vehicle At 201, there is a passenger having a restriction signal transmission terminal R5 having a restriction priority "5" higher than the restriction priority of the restriction signal transmission terminal R1. Here, the passenger having the regulation signal transmitting terminal R5 is, for example, a user who wears a cardiac pacemaker, and transmits a regulation signal of the regulation priority “5” from the regulation signal transmitting terminal R5 to the restricted area E5. Further, the passenger having the regulation signal transmitting terminal R1 is, for example, a user who does not want to make a call near himself or herself, and transmits a regulation signal of the regulation priority "1" from the regulation signal transmitting terminal R1 to the restricted area E1. I have.
[0023]
The mobile communication terminal A is located closer to the regulation signal transmission terminal R1 than the regulation signal transmission terminal R5. However, since the restriction signal transmission terminal R1 suppresses the transmission output of the restriction signal and narrows the restriction area E1, the restriction signal transmission is performed. There is no restriction by the terminal R1. However, since the restriction signal transmission terminal R5 at a farther position raises the transmission output of the restriction signal, the portable communication terminal A is included in the restriction area E5 and is restricted by the restriction priority "5". In this state, the mobile communication terminal A cannot perform a telephone call and data communication under the regulation by the regulation signal of the highest regulation priority "5", but if the passenger carrying the regulation signal transmitting terminal R5 gets off, Since the mobile communication terminal A exits from the restricted area E5, a call or the like can be made. At this time, the use of the mobile communication terminal A is not restricted by the present communication restriction system because even if there is a passenger having the restriction signal transmission terminal R1, the passenger is not in the restriction area E1 of the restriction signal transmission terminal R1.
[0024]
In the example shown in FIG. 5 (b), the restriction signal transmission terminals R11, R12, R13 are close to each other, and transmit restriction signals of restriction priority "1". Here, only the restriction signal transmitting terminal having the restriction priority “1” exists around the mobile communication terminal A, but the mobile communication terminal is located at a position where the restriction areas E11, E12, and E13 created by the respective restriction signal transmission terminals overlap. When A is present, the mobile communication terminal receives a plurality of restriction signals having the same restriction priority. Therefore, in this communication restriction system, according to the restriction value obtained using the added value of each restriction priority as described above, The mobile communication terminal A is regulated with a priority higher than the restriction priority “1”. Accordingly, the use of the mobile communication terminal is regulated in accordance with the number of users who desire regulation, so that regulation in public places can be appropriately performed. In addition,
[0025]
In the above-described example, the restriction signal has a restriction signal transmission terminal ID for uniquely identifying the restriction signal transmission terminal. However, the configuration can be further simplified. For example, the restriction signal transmitted by each restriction signal transmitting terminal may include only the restriction priority. In this case, the restriction signals having the same restriction priority are exactly the same signal, so that the restriction signal transmitting terminal can be made smaller and less expensive. However, since the control priority cannot be managed for each control signal transmitting terminal ID, the number of receptions is stored for each control priority, and the control priority is adjusted according to the number of receptions. Realize flexible regulations according to the number. Normally, the number of times a restriction signal should be received from the restriction signal transmitting terminal is set. If the number of receptions is greater than that, adjustment such as raising the restriction priority is made assuming that a plurality of restriction signals exist.
[0026]
Further, if the restriction signal transmitting terminal ID is used, various determinations as to whether the restriction signal transmitting terminal is a fixed type or a mobile type can be made, and this information can be used for the restriction determination. Thereby, more flexible regulation can be realized. That is, for example, in the case of a mobile type, it is considered that there is little possibility that the restriction will be performed for a long time at the place. In such a case, the restriction is started when the restriction signal is received for a certain time or more. Further, in the case of a fixed station, since it is considered that the area is regularly regulated, the regulation can be started immediately.
[0027]
Further, in the present embodiment, when the signal could not be received accurately, that is, when a plurality of restriction signals are transmitted simultaneously and the restriction signals collide, the received restriction signal is ignored. When there are a large number of restriction signal transmission terminals, the number of collisions increases, and the number of receptions of the restriction signal decreases overall, so that restriction with a lower priority than the restriction that should be performed (relaxed restriction) May be performed. In this case, the actual restriction value may be adjusted by receiving a certain number of imaginary restriction signals having the restriction priority calculated according to the number of collisions of the restriction signal. Thereby, regulation in a region where a plurality of regulation signal transmitting terminals are concentrated can be strengthened, and regulation in such a region can be appropriately performed.
[0028]
Also, with respect to a random time interval at which the restriction signal transmitting terminal transmits the restriction signal, a method of transmitting the restriction signal at a shorter time interval if the restriction priority is high may be considered. It is also desirable that the system be configured to be able to temporarily release this restriction when an emergency call is made to a specific number such as 110, for example. Also, if the mobile communication terminal to be regulated is using the function to be regulated, a warning is given to the user using the display unit, sound generation unit, vibration unit, etc. A grace period may be provided.
Further, in the present embodiment, the call function of the mobile communication terminal is limited according to the regulation value. Alternatively, a warning that the use of the mobile communication terminal is restricted is displayed or sounded. For example, it may be emitted.
[0029]
The effects of the present embodiment will be summarized below.
(1) By simplifying the function and configuration of the regulation signal transmitting terminal, it is possible to make it smaller and cheaper, and it is also possible to make it a key ring type.
(2) It is possible to automatically perform regulation when entering a region to which regulation is to be given, and to automatically release regulation when leaving the region. However, instead of forcibly restricting, a warning may be issued on the display unit to alert the owner.
(3) It is possible to more accurately determine whether or not the vehicle is in an area to be restricted, and to avoid a situation in which a vehicle is not required to be restricted just by passing near the boundary of the restricted area. be able to.
(4) Since it is small and inexpensive, it can be carried by a wearer of a pacemaker and the like, and can be protected from the influence of radio waves and the like even in a city.
(5) It is possible to regulate not only a specific fixed area but also a moving area.
(6) It is possible to perform regulation in consideration of the presence of a plurality of regulation signal transmission terminals.
(7) The priority of regulation can be changed according to the situation.
[0030]
(8) The content of the regulation can be changed according to the situation from the number of regulation signals and the regulation priority. For example, a regulation signal that basically prohibits a ringtone is transmitted in a train. As a result, voice communication is possible if the inside of the vehicle is empty. In addition, when the number of control signals increases due to congestion of vehicles, voice calls are prohibited depending on the degree of the restriction, and communication functions are prohibited when the pacemaker owner approaches, but mail transmission is possible. Will be possible.
(9) In a building, if the antenna of the regulation signal transmitting terminal has directivity or the like, it is possible to create a smaller regulation area.
(10) Since the mobile communication terminal side to be regulated determines the degree of regulation, for example, a mobile phone is prohibited from transmitting and receiving radio waves with the regulation value of “4”, but the PHS is not allowed to transmit and receive radio waves until the regulation value is “6”. For example, transmission / reception is possible, and the content of the regulation can be made different depending on the type of portable communication terminal.
[0031]
