In addition, the transmission / reception unit 7 returns information through the antenna unit 4 in response to requests from the function setting base station 13 and the function setting cancellation base station 14. As described above, since the memory unit 8 stores the function setting code of each portable device, even if the portable device has a different standard by setting a common signal from the function setting base station 13, a predetermined function restriction is set. Transmission from the signal unit 9 is possible. The base station communication means of the first aspect of the present invention corresponds to the antenna unit 4, the power supply rectification unit 6, and the transmission / reception unit 7 in the first embodiment.

  The operation of the communication restriction system according to the first embodiment having the above configuration will be described below with reference to FIGS.

  FIG. 7 is a diagram showing a flow of processing when entering the company 100.

  In step 1S, an information return request for device identification is transmitted from the function setting base station 13 installed at the entrance 101a of the company building 101 to the portable device 1.

  Next, in step 2S, the wireless IC tag generates power by receiving a weak radio wave signal from the function setting base station 13, and the function control unit 3 of the portable device 1 in the memory unit 8 uses the generated power. The recorded device number is returned to the function setting base station 13.

  Next, in step 3S, the comparison unit 23 compares the device number registered in the memory unit 22 of the function setting base station 13 with the device number of the mobile device 1.

  FIG. 8 shows an example of registration of registered device numbers and function setting information. The device number is an absolute number assigned to each portable device. Although the absolute numbers are omitted in FIG. 8, they are managed with 128-bit addresses. For example, devices having device numbers of 3ffe: 551 ...: 0001, 3ffe: 552 ...: 0002 can freely enter the company building 101 without setting functions. Further, when the apparatus having the device numbers 3ffe: 551... 0015: 3ffe: 551... 0022 enters the company building 101, the camera function is stopped. In a portable device that does not correspond to the registered device number (OTHER), a power-off command is forcibly issued.

  In step 3S, if the device number matches the registered device number, the process proceeds to step 4S, and function setting information corresponding to the registered device number is transmitted to the portable device 1. If the device number of the portable device 1 is not in the registered device number in step 3S, it corresponds to OTHER, and the process proceeds to step 5S, where the function setting information of the power-off command is transmitted to the portable device 1. . Step 4S or step 5S corresponds to an example of a function setting information transmission step of the twelfth aspect of the present invention.

  Next, in step 6S, the portable device 1 receives function setting information.

  Next, based on the function setting information received in step 7S and the function setting code stored in the memory unit 8, the setting signal unit 9 performs the corresponding function setting. Step 7S corresponds to an example of a function setting process of the twelfth aspect of the present invention.

  FIG. 9 is a flowchart showing the flow of processing when leaving the company 100.

  First, when the user of the mobile device 1 that has been in the company 100 passes through the gate 102a, a device identification information return request is transmitted from the function setting cancellation base station 14 to the mobile device 1 in step 11S.

  Next, in step 12s, power is generated by the wireless IC tag by receiving a weak radio signal from the function setting cancellation base station 14 (corresponding to an example of a power generation process of the twelfth aspect of the present invention) A device number is returned from the portable device 1 by the generated power.

  Next, in step 13S, the comparison unit 33 compares the device number registered in the memory unit 32 of the function setting cancellation base station 14 with the device number of the mobile device 1.

  FIG. 10 shows a registration example of the device number and function setting release information. 10 shows information for canceling the setting registration information registered in the memory unit 22 shown in FIG. For example, when the registered device number is 3ffe: 551...: 0015, the camera function stop information shown in FIG. 8 is shown in FIG. A portable device that does not correspond to the registered device number (OTHER) is instructed to turn on the power.

  If the device number matches the registered device number in step 13S, the process proceeds to step 14s, and device setting release information corresponding to the registered device number is transmitted to the portable device 1. If the device number does not match the registered device number in step 13S, the process proceeds to step 15s, and a power-on command is transmitted to the portable device 1 as function setting release information.

  Next, in step 16S, the portable device 1 receives function setting release information.

  Next, based on the function setting cancellation information received in step 17S and the function setting code stored in the memory unit 8, the setting signal unit 9 cancels the corresponding function setting. Steps 16S and 17S correspond to an example of a function setting cancellation step of the twelfth aspect of the present invention.

Here, even when the power supply of the portable device 1 is completely turned off, the wireless IC tag generates power by receiving a weak radio wave signal from the function setting cancellation base station 14, and the power supply is turned off. As described above, the communication restriction system according to the first embodiment can restrict functions including turning on and off the power of the portable device within the restricted area.

  In addition, by registering a function to be restricted for each portable device, it is possible to give a degree of freedom to the regulation, not to the same regulation, and to prevent an unnecessary restriction.

  In the first embodiment, the function setting cancellation base station 14 is provided in the gate 102 a located outside the function setting base station 13 with the company building 101 as a reference, and is outside the communication range by the function setting base station 13. By transmitting the function setting cancellation base station 14 signal, the function set at the time of entering can be reliably canceled.

  In the first embodiment, the camera function is set to stop at the entrance 101a. After that, even if the power is turned off due to the battery running out or the like, the weak point from the base station when leaving the company 100. Since the radio wave is used as the driving power of the IC tag, it is possible to reliably cancel the function change.

  As shown in FIG. 11, the function setting base station 13 and the function setting cancellation base station 14 may be provided side by side at the entrance 110a of the place 110 where function setting is restricted, or may be a single base station. In short, it is sufficient that the signal for performing the function setting and the signal for canceling the function setting do not interfere with each other. However, in order to reliably cancel the set function, the communication range 114 of the function setting cancellation base station 14 has a place 110 where the function is changed from the communication range 113 of the function setting base station 13 as shown in FIG. The outer side is more preferable as a reference.

  Further, in the communication restriction system according to the first embodiment, for example, the function setting information “no function setting” is carried with respect to the portable devices with the registered device numbers 3ffe: 551...: 0001, 3ffe: 552. Although it is transmitted to the apparatus, in the case of “no function setting”, the function setting information need not be transmitted. The case where the function setting information is not transmitted corresponds to an example of the case where the function setting information is not transmitted to the mobile communication terminal based on the comparison result by the comparison unit of the second aspect of the present invention.

  In the communication restriction system of the first embodiment, a device identification information return request is transmitted from the function setting cancellation base station 14 and is compared with the device number registered in the memory unit 32. . However, instead of such a configuration, when the portable device 1 sets a function in the setting signal unit 9, the set function is stored in the memory unit 8, and only a cancellation command is issued from the function setting cancellation base station 14. The structure which transmits may be sufficient. In this case, the portable device 1 cancels the setting based on the set information stored by itself by the cancel command. In short, it is only necessary to cancel the changed function when entering the company building 101.

  Further, in the first embodiment, one function setting base station 13 is provided at the entrance 101a, but it is not limited to the entrance 101a, and may be in the vicinity of the company building 101 where the function is restricted. The function setting base stations 13 may be provided at a plurality of locations in the company building 101. In short, it is only necessary to limit a predetermined function in the company building 101. Needless to say, the function setting cancellation base station 14 is not limited to the location of the gate 102a, and when there are a plurality of gates, the function setting cancellation base station 14 may be installed at a plurality of locations.

  In the first embodiment, power generation is performed by the energy of radio waves received from either the function setting base station 13 or the function setting cancellation base station 14, but the radio waves from only the function setting cancellation base station 14 are generated. Power generation may be performed only by

  However, in the case where the power generation is also performed by the radio wave from the function setting base station 13, even if the user of the portable device 1 enters the office building 101 with the power turned off in advance, the function setting is performed at the entrance 101a. By communication from the base station 13, power generation is performed in the portable device 1 and function settings are made. Therefore, even if the user enters the building 101 with the power turned off and the user of the mobile device 1 tries to turn on the power by mistake or uses the function of the mobile device 1 after turning on the power, the function is set. It cannot be used. Since the function can be surely restricted in this way, it is more preferable that the power generation is performed by the radio wave from the function setting base station 13.

  In the first embodiment, the power OFF is instructed to a number not registered in the memory unit 22, but function setting information for prohibiting the power ON operation may be transmitted at the same time. In this case, since turning on the power in the company building 101 is restricted, the operation of turning on the power in the company building 101 can be more reliably prohibited.

  Moreover, in this Embodiment 1, the portable apparatus 1 is equipped with the transmission / reception part separately from the transmission / reception part 2 which performs a normal call, and the transmission / reception part 7 which communicates with the function setting base station 13 and the function setting cancellation | release base station 14. However, the transmission / reception unit 2 may also serve as the transmission / reception unit 7, and the antenna unit (not shown) for the transmission / reception unit 2 may also serve as the antenna unit 4 for the transmission / reception unit 7.

  In the first embodiment, the company 100 is described as an example. However, the communication restriction system of the first embodiment needs to restrict the functions of portable devices such as hospitals, aircraft, exhibitions, and movie theaters. Applicable to places with

(Embodiment 2)
Hereinafter, the mobile communication terminal according to the second embodiment will be described.

  The portable device according to the second embodiment, which is an example of the mobile communication terminal of the present invention, sets functions based on absolute position information consisting of latitude and longitude information on the earth using GPS (global positioning system). Is done.

As shown in FIG. 12, the portable device 40 according to the second embodiment includes a transmission / reception unit 41 that performs normal conversation, a function control unit 42 that changes and releases functions of the portable device 40, and a main body of the portable device 40. A battery 45 that supplies power to the function control circuit unit 44 of the function control unit 42 is provided so that radio waves from the satellite can be received even when the power is off. FIG. 13 is a configuration diagram of the function control unit 42. As shown in FIG. 13, the function control unit 42 includes an antenna unit 43 for receiving a signal from a satellite and a function control circuit unit 44. The battery 45 is preferably shared with an internal battery for a clock or the like of the portable device 40.

  FIG. 14 is a configuration diagram of the function control circuit unit 44. The function control circuit unit 44 includes a receiving unit 46 for demodulating a signal by the antenna unit 43, and a position detecting unit 50 for converting the demodulated signal into latitude / longitude information and detecting a current position. In addition, a memory unit 47 that stores position information and function setting information corresponding to the position information, and a position comparison unit 51 that compares position information registered in the memory unit 47 with the current position are installed. . Further, based on the result of the position comparison means 51, a setting signal unit 48 for transmitting a predetermined command in accordance with the registered position information and function setting information is provided.

  An example of the storage means according to the tenth aspect of the present invention corresponds to the memory unit 47, and an example of the comparison means according to the tenth aspect of the present invention corresponds to the position comparison means 51. The function setting means of the tenth aspect of the present invention corresponds to the setting signal unit 48.

  Further, the function setting contents transmitted from the setting signal unit 48 are a function stop command 11, a forced operation command 12, and a function release command 10 as in the first embodiment.

  FIG. 15 is a diagram showing an example of registered position information and setting function data. As shown in FIG. 15, for example, the position of hospital A is 34 degrees 40 minutes 15 seconds north, position information data of 135 degrees 32 minutes 10 seconds east longitude, and a power OFF command is set as function setting information corresponding to hospital A. Registered in the memory unit 47.

  The operation of the portable device of the second embodiment having the above configuration will be described below.

  The portable device of the second embodiment periodically receives a signal from the satellite, receives a signal from the satellite by the antenna unit 43, demodulates the signal received by the transmission / reception unit 46, and detects the position detection unit 50. Is converted into position information of longitude and latitude (corresponding to an example of a position detection step of the thirteenth aspect of the present invention). Thereby, the portable device 40 can recognize the current position.

  Next, the position comparison means 51 compares the current position with the position information registered in the memory unit 47 (corresponding to an example of a position comparison process of the thirteenth aspect of the present invention). As a result, when the mobile device 40 is included in the registered position information, function setting corresponding to the position information (function stop, forced operation, etc. as in the first embodiment) is performed by the setting signal unit 48. (This corresponds to an example of a function setting step of the thirteenth aspect of the present invention). Then, information on the function set in the memory unit 47 is stored. For example, when the position information of hospital A shown in FIG. 15 is entered, a power-off command is issued by the setting signal unit 48, and the memory unit 47 stores that the power-off command has been issued.

  In the second embodiment, the position information is registered as, for example, 34 degrees 40 minutes 15 seconds north in the hospital A and 135 degrees 32 minutes 10 seconds east longitude, and the current position detected by the GPS is 34 degrees north latitude. 40 minutes 14 seconds <north latitude of current position detected <34 degrees 40 minutes 16 seconds north latitude and 135 degrees 32 minutes 9 seconds east longitude <east longitude of detected current position <135 degrees 32 minutes 11 seconds east longitude In that case, I entered hospital A. This position information may be widened, for example, 34 degrees 40 minutes 10 seconds north latitude 34 degrees 40 minutes 15 seconds, or 34 degrees 40 minutes 15.2 seconds north latitude 34 degrees 40 minutes 15.7 seconds.
