Description

  The present invention relates to a mobile terminal device, a function restriction method, and a program.

  There has been proposed a technology for automatically limiting various functions of a mobile terminal device (hereinafter, appropriately referred to as a limiting technology). The mobile terminal device is, for example, a mobile phone, a smart phone, or a tablet terminal device.

  A portable terminal device having such a restriction technique acquires function restriction information (hereinafter referred to as restriction information as appropriate) indicating the contents of the function restriction of the portable terminal device from another device. This function restriction is, for example, to stop the voice output function of the mobile terminal device.

  Such a portable terminal device restricts the function of the portable terminal device based on the read restriction information. When the function restriction stops the voice output function of the portable terminal device, the portable terminal device stops voice output based on the read restriction information (shifts to a so-called manner mode).

The first portable terminal device 1a to the third portable terminal device 1c are movable terminal devices, and are devices having a communication function such as a mobile phone, a smartphone, and a tablet terminal device.

  RFID tags 2 are installed in various places such as public facilities, private facilities, stations, and bus stops. For example, the RFID tag 2 is installed at an event venue such as a concert or an entrance of a library or a movie theater. RFID is an abbreviation for “Radio Frequency IDentification”. The RFID tag 2 is, for example, an active tag. An RFID tag is also called an RF tag.

  The RFID tag 2 wirelessly transmits restriction information indicating the contents of restriction on the functions of the mobile terminal device. The restriction information will be described with reference to FIG.

The core network is also called a backbone line, a trunk line network, or a carrier network, and is a network that relays the first base station 3a, the second base station 3b, and the large-scale network NT. The large-scale network NT is, for example, the Internet.

  The management server 4 is a server (also referred to as an information processing device) that manages restriction information and the like of the first mobile terminal device 1a to the third mobile terminal device 1c.

  Reference numerals S1 to S11 shown in FIG. 1 correspond to the steps in the flowchart of FIG. Note that reference symbols R1 and P11 to P14 shown in FIG. 1 will be described with reference to FIG. 2, and reference symbol MV will be described with reference to FIG.

[Restriction information]
FIG. 2 is a diagram illustrating the restriction information described in FIG. The restriction information IF1 in FIG. 2 is an example of information indicating the content of restriction on the function of the mobile terminal device.

  The restriction information IF1 includes a restriction type indicating a function restriction type, position information indicating a position to which the restriction type is applied, and a time limit indicating a time zone in which the restriction type is applied.

  The restriction information IF1 includes a position information line indicating position information, a restriction type line indicating a restriction type, and a time limit line indicating a time limit. The position information line has a vertex line indicating a vertex that specifies a range (also referred to as a limited range) indicated by the position information to which the restriction type is applied, and a number line indicating the number of the vertexes. The time limit line includes a start time line indicating the start time of the time limit period to which the limit type is applied, and an end time line indicating the end time of the time limit period. Note that reference numeral STR1 will be described with reference to FIG.

  In the restriction information IF1, the position where the restriction type “Manner mode” is applied is specified by vertices P11, P12, P13, and P14 (see FIG. 1). A quadrangle identified by the vertices P11, P12, P13, and P14 shown in FIG. 1 is indicated by a limited range R1 in FIG. In the limit information IF1, the number of vertices P11, P12, P13, and P14 is indicated by “4”. Further, in the restriction information IF1, the vertex P11 is indicated by “latitude p11, longitude p11”, the vertex P12 is indicated by “latitude p12, longitude p12”, the vertex P13 is indicated by “latitude p13, longitude p13”, and the vertex P14 is indicated by “ Latitude p14, longitude p14 ".

  In the restriction information IF1, the start time and end time of the restriction time zone to which the restriction type “Manner mode” is applied are shown as “10:00” and “20:00”, respectively.

  The restriction information IF1 is transmitted from “10:00” to “20: This is information for instructing to switch to the manner mode (after the sound output is stopped) during 00 ".

  The RFID tag 2 shown in FIG. 1 transmits, for example, the restriction information IF1 shown in FIG. 2 by radio. The mobile terminal device located in the range where the radio wave output from the RFID tag 2 can reach (hereinafter referred to as the radio wave range as appropriate) receives the restriction information IF1 sent from the RFID tag 2 and stores it in its own device.

  When the portable terminal device that stores the restriction information IF1 in its own device is located inside the restriction range R1 indicated by the four vertices P11, P12, P13, and P14, the manners are between “10:00” and “20:00”. Transition to mode automatically.

  Note that the position information for specifying the restriction range R1 is not limited to four vertices. The restricted range may be indicated by, for example, one point and a circle with a radius centered on this point.

  The distance at which wireless communication between the portable terminal device (for example, the first portable terminal device 1a) and the RFID tag 2 is possible (hereinafter referred to as a wireless communication possible distance as appropriate) is short. In other words, since the radio wave output of the RFID tag 2 is weak, the radio wave range that the radio wave reaches is narrow, and this wireless communication possible distance is short. Normally, the wireless communication range is about several meters.

  For example, assume that the RFID tag 2 is installed at the entrance of a movie theater or library. Under such assumptions, even if a user who owns a mobile terminal device enters a movie theater or library from the entrance, it may pass outside the radio wave range of the RFID tag 2 because the wireless communication distance is short as described above. is there. As a result, this mobile terminal device may not be able to acquire the restriction information IF1 from the RFID tag 2.

  Even if the mobile terminal device is located in the radio wave range of the RFID tag 2, the mobile terminal device may not be able to acquire the restriction information IF1 transmitted by the RFID tag 2 due to the influence of an obstacle or the like. In particular, when a person is congested within the radio wave range of the RFID tag 2, the radio wave may be blocked by the person, and the mobile terminal device may not be able to acquire the restriction information IF1 transmitted by the RFID tag 2. Get higher.

  Even when the portable terminal device according to the present embodiment cannot acquire the restriction information IF1 transmitted from the RFID tag 2, it executes the processing described below and stores the restriction information IF1 in its own device.

With reference to FIG. 1, operations of the mobile terminal device and the management server in the present embodiment will be described. For example, the first mobile terminal device 1a succeeds in obtaining the restriction information IF1 transmitted from the RFID tag 2 (S1 in FIG. 1). Then, the first mobile terminal device 1a transmits the restriction information IF1 to the management server 4 via the first base station 3a (S2).

  When the restriction information IF1 is not stored in the own device, the management server 4 transmits restriction information including the restriction information IF1 to the first base station 3a (S4). Then, the management server 4 transmits, to the first base station 3a, a signal instructing a plurality of mobile terminal devices wirelessly connected to the first base station 3a to broadcast information including the restriction information IF1. (S4). In FIG. 1, the plurality of portable terminal devices are a first portable terminal device 1a and a second portable terminal device 1b.

Step S6: The transmission / reception unit 14 of the second mobile terminal device 1b receives the restriction information STR4 ′ broadcasted by the first base station 3a and stores it in the restriction information storage area IR1 of the storage 102. By the process of S6, even if the portable terminal device has not read the restriction information IF1, the restriction information IF1 can be stored in its own device.

(Processing in the first portable terminal device 1a)
Step S7: The transmission / reception unit 14 of the first mobile terminal device 1a receives the restriction information STR4 ′ broadcasted by the first base station 3a and stores it in the restriction information storage area IR1 of the storage 102.

  Next, the processing when the user C who owns the third mobile terminal device 1c moves from the wireless communication area of the second base station 3b to the wireless communication area RN of the first base station 3a is described in S8 to S11. I will explain it.

(Processing in the third portable terminal device 1c)
Step S8: When the restriction information transmission request unit 15 of the third portable terminal device 1c is located in another base station, the restriction information transmission request part 15 sends restriction information to the management server 4 via the first base station 3a that is located. Make a request. Specifically, as shown in FIG. 1, the third mobile terminal device 1c moves from the wireless communication area of the second base station 3b into the wireless communication area RN of the first base station 3a (reference numeral (See MV).

(Processing on Management Server 4)
Step S9: Upon receiving the restriction information transmission request, the transmission / reception unit 42 of the management server 4 transfers the restriction information transmission request to the restriction information broadcast unit 44.

  Step S10: Upon receiving the restriction information transmission request, the restriction information broadcast unit 44 sends the restriction information STR4 ′ stored in the restriction information storage area IR2 of the storage 402 to the third mobile phone via the first base station 3a. Transmit to the terminal device 1c.

(Processing in the third portable terminal device 1c)
Step S11: The transmission / reception unit 14 of the third portable terminal device 1c receives the restriction information STR4 ′ and stores it in the restriction information storage area IR1 of the storage 102.

  Through the processing of S11, the third portable terminal device 1c can store the restriction information IF1 in its own device.

  As described with reference to FIG. 9, the first mobile terminal device 1a transmits the restriction information IF1 read from the RFID tag 2 to the management server 4 (S2 in FIG. 9). Then, the second portable terminal device 1b can receive the restriction information IF1 read by the first portable terminal device 1a from the management server 4 via the first base station 3a (S6 in FIG. 9).

  Further, when the third mobile terminal device 1c is in the wireless communication area RN of the first base station 3a, the third mobile terminal device 1c may also receive the restriction information IF1 transmitted from the management server 4. Yes (S11 in FIG. 9).

  Wireless communication between a base station and a mobile terminal device located within the wireless communication range of the base station uses a wireless communication system such as LTE or 3G. The radio communication area of the base station is wider than the radio wave range of the RFID tag, and the radio field intensity of the radio communication between the base station and the mobile terminal apparatus is greater than the radio field intensity of the radio communication between the RFID tag and the mobile terminal apparatus. Is also strong. Therefore, the mobile terminal device can reliably perform wireless communication with the base station as compared with wireless communication with the RFID tag. As a result, the mobile terminal device can reliably receive the restriction information from the base station through wireless communication with the base station.

  In the example of FIG. 9, the mobile terminal device located in the wireless communication area RN of the first base station 3a to which the first mobile terminal device 1a is wirelessly connected receives the restriction information IF1 from the management server 4. It can be received reliably. In other words, if one mobile terminal device among a plurality of mobile terminal devices located in the wireless communication area RN of the first base station 3a succeeds in reading the restriction information IF1, the plurality of mobile terminal devices All portable terminal devices can share the restriction information IF1.

  As a result, the mobile terminal device located in the wireless communication area RN of the first base station 3a functions based on the received restriction information IF1 even if the restriction information IF1 cannot be read from the RFID tag 2. Restrictions can be enforced.

  Here, the reason why the base station broadcasts the restriction information to the mobile terminal devices located in the wireless communication range (S4 and S5 in FIG. 9) will be described. A mobile terminal device located within the wireless communication area of the base station is likely to fall within the restriction range of restriction information transmitted by the RFID tag installed within this wireless communication area. Therefore, when such a portable terminal device enters this restriction range, the portable terminal device located within the wireless communication area of the base station can automatically execute function restriction based on this restriction information. Broadcast restriction information to

[Detailed description of the flow diagram in Fig. 9]
The flowchart of FIG. 9 will be described in detail with reference to FIGS.

(Reading and sending restriction information on mobile terminal devices)
FIG. 10 is a flowchart for explaining reading and transmission of restriction information in the mobile terminal device. Specifically, FIG. 10 is a flowchart illustrating in detail the processing of S1 and S2 described in FIG. In the following, S21 is a detailed description of S1 in FIG. 9, and S22 to S25 are a detailed description of S2 in FIG.

  Step S21: The restriction information reading device 110 of the first portable terminal device 1a reads the restriction information IF1 from the RFID tag 2 and stores it in the RAM 103. The restriction information reading unit 12 reads the restriction information IF1 stored in the RAM 103 and outputs it to the restriction information comparison unit 13.

  Step S22: The restriction information comparison unit 13 determines whether or not a restriction type is included in the input restriction information IF1. Specifically, the restriction information comparison unit 13 determines whether the restriction information received includes restriction types such as “Manner mode” and “Camera stop mode”. If the restriction type is not included (S22 / NO), the process is terminated, and the function restriction process described with reference to FIG. On the other hand, when the restriction type is included (S22 / YES), the process proceeds to S23.

  In S23 and S24 described below, the restriction information comparison unit 13 determines whether the read restriction information IF1 of the RFID tag 2 is stored in the restriction information storage area IR1 of the storage 102.

  Step S23: The restriction information comparison unit 13 of the first mobile terminal device 1a compares the restriction information IF1 of the RFID tag 2 with the restriction information stored in the restriction information storage area IR1 of the storage 102.

  Step S24: The restriction information comparison unit 13 of the first mobile terminal device 1a determines whether the restriction information IF1 of the RFID tag 2 is included in the restriction information stored in the restriction information storage area IR1 of the storage 102. This comparison (S23) and determination (S24) will be described in detail with reference to FIG.

  When the restriction information IF1 of the RFID tag 2 is included in the restriction information stored in the restriction information storage area IR1 (S24 / YES), the process proceeds to the function restriction process described with reference to FIG. If the restriction information IF1 of the RFID tag 2 is not included in the restriction information stored in the restriction information storage area IR1 (S24 / NO), the process proceeds to S25.

  Step S25: The transmission / reception unit 14 of the first portable terminal device 1a transmits the restriction information IF1 of the RFID tag 2 to the management server 4. In S25, the transmitting / receiving unit 14 of the first mobile terminal device 1a performs an identifier (hereinafter referred to as a base station ID as appropriate) of a base station (for example, the first base station 3a) to which the first mobile terminal device 1a is connected. And the restriction information IF1 is transmitted to the management server 4.

  When the processing of S25 ends, the process proceeds to the function restriction process of FIG. 15 and shifts to a waiting state for receiving restriction information from the management server 4.

  Here, as described in S24 of FIG. 10, the first portable terminal device 1a has the restriction information IF1 read from the RFID tag 2 already stored in its own device (S24 / NO). This restriction information is not transmitted to the management server 4. By this processing, when a large number of portable terminal devices 1 read the restriction information IF1 from the RFID tag 2, it is possible to prevent the restriction information IF1 from being transmitted to the management server 4 at the same time. With this prevention, it is possible to prevent network congestion due to the restriction information IF1 being transmitted to the management server 4 all at once.

  In addition, for example, when the mobile terminal device 1 continues to be in the radio wave range of the RFID tag 2 and the restriction information IF1 of the RFID tag 2 is read many times, the restriction information is transmitted to the management server 4 only once. To do. For this reason, useless processing of repeatedly transmitting the same restriction information is not executed, so that it is possible to reduce processing load and useless power consumption.

(Reception and update of restriction information on the management server)
FIG. 11 is a flowchart illustrating reception and update of restriction information in the management server. Specifically, FIG. 11 is a flowchart for explaining in detail the processing of S3 and S4 described in FIG. Hereinafter, S31 and S32 are detailed descriptions of S3 in FIG. 9, and S33 to S35 are detailed descriptions of S4 in FIG.

  Step S31: The transmission / reception unit 42 of the management server 4 receives the restriction information IF1 transmitted from the first portable terminal device 1a and stores it in the RAM 403.

  Step S32: The restriction information comparison unit 43 of the management server 4 compares the restriction information stored in the restriction information storage area IR2 of the storage 402 with the received restriction information IF1.

  Specifically, the restriction information comparison unit 43 reads restriction information stored in the restriction information storage area IR2 of the storage 402 in association with the base station ID transmitted together with the restriction information IF1. Then, the restriction information comparison unit 43 compares the read restriction information with the restriction information IF1 stored in the RAM 403.

  The base station ID is, for example, an identifier of the first base station 3a. The restriction information STR4 in FIG. 7 is stored in association with this identifier. Therefore, the restriction information comparison unit 43 reads the restriction information STR4 stored in the restriction information storage area IR2 of the storage 402 in association with the base station ID of the first base station 3a transmitted together with the restriction information IF1. Then, the restriction information comparison unit 43 compares the restriction information STR4 with the received restriction information IF1.

  Step S33: The restriction information comparison unit 43 of the management server 4 determines whether or not the received restriction information IF1 is included in the restriction information STR4 stored in the restriction information storage area IR2 of the storage 402. When the received restriction information IF1 is included in the restriction information STR4 (S33 / YES), the process returns to S31 and shifts to a restriction information reception waiting state. If the received restriction information IF1 is not included in the restriction information STR4 (S33 / NO), the process proceeds to S34.

  In the example of S32, when the restriction information IF1 in FIG. 2 is compared with the restriction information STR4 in FIG. 7, the restriction information IF1 in FIG. 2 is not included in the restriction information STR4 in FIG. When comparing the restriction information IF1 in FIG. 2 with the restriction information STR4 in FIG. 7, the position information of the restriction information IF1 and the position information of the restriction information STR4 (in other words, the position information of the restriction information IF2, IF3, and IF4) ).

  Then, if any of the position information of the restriction information IF2, IF3, IF4 matches the position information of the restriction information IF1, it is determined that the restriction information IF1 is included in the restriction information STR4.

  In comparison of position information, the top vertices in the position information column may be compared to determine whether they match. For example, the position information vertices P21, P31, and P41 in the restriction information IF2, IF3, and IF4 in FIG. 7 may be compared with the position information vertex P11 in the restriction information IF1 in FIG. 2 to determine whether they match. Next, the restriction information broadcast unit 44 performs restriction information update processing as described in S34.

  Step S34: The restriction information broadcast unit 44 of the management server 4 creates restriction information (see FIG. 8) including the restriction information IF1 and the restriction information STR4, and replaces the restriction information STR4 with the restriction information storage area of the storage 402. Store in IR2.

  The restriction information stored in the restriction information storage area IR2 is restriction information STR4 ′. Here, the restriction information broadcast unit 44 stores restriction information STR4 ′ in the restriction information storage area IR2 in association with the base station ID. The base station ID is an identifier of the first base station 3a connected to the first mobile terminal device 1a that has transmitted the restriction information IF1.

  Step S35: The restriction information broadcast unit 44 of the management server 4 adds the restriction information STR4 ′ newly created to the first base station 3a connected to the first portable terminal device 1a that has transmitted the restriction information IF1. , An instruction signal instructing to broadcast the restriction information STR4 ′ is transmitted.

  In response to this instruction signal, the first base station 3a broadcasts the restriction information STR4 ′ to all mobile terminal devices located within the wireless communication area RN (S5 in FIG. 9).

  If the received restriction information IF1 is not included in the restriction information STR4 in the restriction information storage area IR2 of the storage 402 (S33 / YES), the management server 4 does not transmit the restriction information STR4 ′. The reason for not transmitting is to prevent the restriction information STR4 ′ from being repeatedly created and transmitted (S34, S35) when the restriction information IF1 is sequentially received from a plurality of terminals. This prevention can suppress the processing load.

(Reception and update of restriction information in mobile terminal devices)
FIG. 12 is a flowchart illustrating reception and update of restriction information in the mobile terminal device. Specifically, FIG. 12 is a flowchart illustrating in detail S6 and S7 in FIG. In FIG. 12, for example, reception and update of restriction information (see S7) in the first mobile terminal device 1a will be described, but other mobile terminal devices (eg, the second mobile terminal device 1b (see S6)) will also be described. It is the same.

  Step S61: The transmission / reception unit 14 of the first mobile terminal device 1a receives the restriction information STR4 ′ broadcasted by the first base station 3a.

  Step S62: The transmission / reception unit 14 of the first mobile terminal device 1a stores the received restriction information STR4 ′ in the restriction information storage area IR1 of the storage 102. That is, the transmission / reception unit 14 performs restriction information update processing.

  With the processing in FIG. 12, the mobile terminal device can reliably acquire the restriction information.

(Restriction information transmission request and update in mobile terminal device)
FIG. 13 is a flowchart for explaining a restriction information transmission request and reception process in the mobile terminal device. Specifically, FIG. 13 is a flowchart for explaining in detail the processing of S8 and S11 described in FIG. The mobile terminal device executes the process described with reference to FIG. 13 periodically (for example, at intervals of 5 seconds and 10 seconds). In the following, S81 to S83 are detailed descriptions of S8 in FIG. 9, and S84 and S85 are detailed descriptions of S11 in FIG.

  Step S81: The communication device 109 of the third mobile terminal device 1c executes cell search.

  Step S82: The restriction information transmission request unit 15 of the third portable terminal device 1c determines whether the connected base station has changed as a result of the cell search of S81. Then, the restriction information transmission request unit 15 stores the determination result in the RAM 103.

  If the base station has not changed (S82 / NO), the process proceeds to S81. If the base station has changed (S82 / YES), the process moves to S83.

  In the example of FIG. 1, a user C who has the third mobile terminal device 1c moves from the wireless communication area of the second base station 3b into the wireless communication area RN of the first base station 3a (in FIG. 1). (See symbol MV). During this movement, the communication device 109 of the third mobile terminal device 1c performs a cell search (S81), switches the base station to be connected from the second base station 3b to the first base station 3a, The location of the own device is registered in the base station 3a. As a result, the restriction information transmission request unit 15 of the third portable terminal device 1c determines that the connected base station has changed.

  Step S83: The restriction information transmission request unit 15 of the third mobile terminal device 1c includes the restriction information together with the base station ID of the base station (for example, the first base station 3a) to which the third mobile terminal device 1c is connected. A transmission request is transmitted to the management server 4.

  Step S84: The transmission / reception unit 14 of the third portable terminal device 1c receives the restriction information transmitted from the management server 4 in response to the restriction information transmission request. The restriction information transmitted from the management server 4 is, for example, the restriction information STR4 ′ in FIG. The process in which the management server 4 transmits the restriction information will be described with reference to FIG.

  Step S85: The transmission / reception unit 14 of the third portable terminal device 1c stores the received restriction information in the restriction information storage area IR1 of the storage 102. That is, the transmission / reception unit 14 performs restriction information update processing.

(Response to restriction information transmission request in the management server)
FIG. 14 is a flowchart for explaining a response to the restriction information transmission request in the management server. Specifically, FIG. 14 is a flowchart illustrating in detail S9 and S10 in FIG. Hereinafter, S91 and S92 are detailed descriptions of S9 in FIG. 9, and S93 and S94 are detailed descriptions of S10 in FIG.

  In the description of FIG. 14, as described in S83 of FIG. 13, the restriction information transmission request unit 15 of the third mobile terminal device 1c is connected to the first base station 3a to which the third mobile terminal device 1c is connected. A restriction information transmission request is transmitted to the management server 4 together with the base station ID.

  Step S91: The transmission / reception unit 42 of the management server 4 executes reception waiting processing for the restriction information transmission request transmitted from the mobile terminal device.

  Step S92: The transmission / reception unit 42 of the management server 4 determines whether a restriction information transmission request has been received. When the restriction information transmission request is not received (S92 / NO), the process proceeds to S91. When a restriction information transmission request is received (S92 / YES), the process proceeds to S93.

  Step S93: The restriction information broadcast unit 44 of the management server 4 reads the restriction information stored in the restriction information storage area IR2 of the storage 402 in association with the base station ID received together with the restriction information transmission request. For example, the restriction information broadcast unit 44 reads the restriction information STR4 ′ stored in the restriction information storage area IR2 of the storage 402 in association with the base station ID of the first base station 3a.

  Note that when the transmission / reception unit 42 of the management server 4 receives the restriction information transmission request and the base station ID, the transmission / reception unit 42 outputs the restriction information transmission request 44 to the restriction information broadcast unit 44.

  Step S94: The transmission / reception unit 42 of the management server 4 transmits the read restriction information STR4 ′ to the third portable terminal device 1c that has transmitted the restriction information transmission request.

  The transmission / reception unit 14 of the third mobile terminal device 1c receives the restriction information transmitted from the management server 4 (S84 in FIG. 13).

(Function restrictions based on restriction information)
FIG. 15 is a flowchart for explaining function restriction based on restriction information, which is executed by the mobile terminal device. FIG. 15 illustrates, for example, a case where the first mobile terminal device 1a executes function restriction based on restriction information. As described in FIG. 11, the first mobile terminal device 1a stores the restriction information STR4 ′ transmitted from the management server 4 in the restriction information storage area IR1 of the storage 102. The first mobile terminal device 1a executes the process of S101 at intervals of 30 seconds, for example.

  Step S101: The position information acquisition unit 16 of the first mobile terminal device 1a reads the position information stored in the RAM 103 by the position measurement device 111 from the RAM 103 and outputs it to the function restriction unit 18.

  Step S102: The function restriction unit 18 of the first portable terminal device 1a reads the restriction information STR4 ′ from the restriction information storage area IR1 of the storage 102.

  Step S103: The function restriction unit 18 of the first portable terminal device 1a compares the above-described position information with the position information in the restriction information IF1 to IF4 of the restriction information STR4 ′, and the first portable terminal device 1a It is determined whether it is located within. When the first mobile terminal device 1a is not located within the restriction range (S103 / NO), the processing in FIG. 15 is terminated. When the first portable terminal device 1a is located within the limit range (S103 / YES), the process proceeds to S104.

  For example, the position information stored in the RAM 103 by the position measurement device 111 is latitude p10 and longitude p10, and the positions indicated by the latitude p10 and longitude p10 are within the restriction range R1 indicated by the vertices P11 to P14 in the restriction information IF1 (see FIG. 1).

  In the case of this example, the function restriction unit 18 of the first mobile terminal device 1a determines that the first mobile terminal device 1a is located within the restriction range R1. Hereinafter, when the current position of the mobile terminal device is located within the restriction range indicated by the restriction information, this restriction information is referred to as target restriction information. In the above example, the target functionality information is the restriction information IF1.

  Step S104: The function restriction unit 18 of the first portable terminal device 1a determines whether or not the current time is included in the restriction time zone of the target restriction information. If the current time is not included in the time limit of the target limit information (S104 / NO), the processing in FIG. 15 is terminated. If the current time is included in the time limit of the target limit information (S104 / YES), the process proceeds to S105.

  In the example described in S103, when the current time is “12:00”, for example, this current time is included in the time limit (10:00 to 20:00) of the limit information IF1.

  Step S105: The function restriction unit 18 of the first portable terminal device 1a executes the restriction type of the target restriction information. In the example described in S103, the function restriction unit 18 executes the restriction type “manner mode” of the restriction information IF1. When the restriction type is “manner mode”, for example, when there is an incoming call, the function restriction unit 18 of the first portable terminal device 1a stops the voice output of the voice input / output device 106 and vibrates the vibration device 105. Then, the user is notified of the incoming call by this vibration.

  Note that the time limit end determination unit 19 of the first mobile terminal device 1a to the third mobile terminal device 1c is the end time of the time limit indicated by the limit information stored in the limit information storage area IR1 of the storage 102. Determine whether has passed. When the time limit end determination unit 19 determines that the end time of the time limit has elapsed, the time limit end determination unit 19 deletes the time limit information from the storage 102. When the limit information IF1 of FIG. 2 is stored in the limit information storage area IR1, the limit time end determination unit 19 deletes the limit information IF1 from the storage 102 when the end time “20:00” elapses.

  Similarly, the time limit end determination unit 45 of the management server 4 determines whether the end time of the time limit indicated by the limit information stored in the limit information storage area IR2 of the storage 402 has elapsed. When the time limit end determination unit 45 determines that the end time of the time limit has elapsed, the time limit end determination unit 45 deletes the time limit information from the storage 402.
