Description

  The present invention relates to an information notification apparatus, an information notification method, and an information notification system for notifying a user of information corresponding to a roaming direction of a mobile device.

  In recent years, roaming has become possible between networks of different communication companies, and roaming has become possible internationally. In general, when a mobile device is located in a home network, the fee system is set to be cheaper by a contract with a communication company. However, if the mobile device is located in a roaming network provided by an overseas telecommunications company or the like, the charge system is often set at a high price.

Therefore, conventionally, when the mobile device roams from the home network to the roaming network, the mobile device that displays the charging system in the roaming network when performing location registration, communication, telephone conversation, etc. of the mobile device (hereinafter referred to as “during communication”) Has been considered (see Patent Document 1).
Japanese Patent Application No. 2006-295684

  However, the conventional mobile device simply notifies the roaming destination billing system, and thus has a problem that the billing system cannot be notified according to the roaming direction.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an information notification apparatus, an information notification method, and an information notification system that can improve user operability by notifying information according to the roaming direction.

  An information notification apparatus according to the present invention is an information notification apparatus that notifies a user of a billing system of a mobile communication network in which a mobile device is located, and includes a location information acquisition unit that acquires location information of the mobile device, The roaming direction determining means for determining the roaming direction based on the previously acquired area information and the currently acquired area information in the area information acquiring means, and the area information previously acquired in the area information acquiring means and this time acquired And a notification means for notifying a user of information corresponding to a roaming direction during communication of a mobile device when the location information is different.

  In the information notification apparatus according to the present invention, if the previously acquired location information is different from the currently acquired location information, the roaming direction is determined, and information according to the roaming direction is notified to the user. Therefore, for example, when roaming from a roaming network to a home network, or when roaming between roaming networks with different charging systems, it is possible to notify the user of appropriate information according to the roaming direction, and user operability Can be improved.

  The information notification apparatus according to the present invention further includes a charging system acquisition unit that acquires a charging system of a mobile communication network in which the mobile device is located, and the notification unit includes the area information acquired last time by the area information acquisition unit. When the location information acquired this time is different from the currently acquired location information, it is preferable to notify the user of the charging system according to the roaming direction during communication of the mobile device.

  In this information notification device, if the previously acquired location information is different from the currently acquired location information, the charging system of the mobile communication network that is in the location is notified to the user according to the roaming direction. For this reason, for example, when roaming from a roaming network to a home network, or when roaming between roaming networks with different charging systems, notification of an appropriate charging system can be performed according to the direction of roaming, and user operability Can be improved. In addition, since the accounting system is notified at the time of communication of the mobile device, it is possible to prevent the user operability from being deteriorated due to frequent notification of the accounting system.

  In this case, when the notification unit determines that the roaming out from the home network to the roaming network, it is preferable to notify the user of the charging system of the roaming network.

  In this information notification device, when the mobile device roams out from the home network to the roaming network, the charging system of the roaming network that is the roaming destination is notified to the user. In other words, in general, the charging system is set to be lower in the home network with which the user is contracted, whereas the charging system is set to be higher in the roaming network than in the home network. For this reason, it is possible to prevent the user from being charged for an unintended high communication fee by performing communication or the like without knowing the charging system of the roaming network that is the roaming destination.

  Further, when the notification means determines that the roaming in from the roaming network to the home network is made, it is preferable not to notify the user of the charging system of the home network.

  In this information notification device, when the mobile device roams in from the roaming network to the home network, the charging system of the home network that is the roaming destination is not notified to the user. That is, in general, the charging system is set to be lower for the home network with which the user is contracted than the roaming network, and the user is aware of the charging system for the home network. For this reason, when roaming in from the roaming network to the home network, there is no particular disadvantage to the user without notifying the charging system of the home network. Therefore, in such a case, by not reporting the billing system, it is possible to prevent the user operability of the mobile device from being degraded due to unnecessary notification.

  In addition, when the notifying unit determines that the roaming network has roamed to another roaming network with a higher charging system, it is preferable to notify the user of the charging system of the roaming network that is the roaming destination.

  In this information notification device, when a mobile device roams from a roaming network to another roaming network having a higher charging system than the roaming network, the user is notified of the charging system of the roaming network that is the roaming destination. That is, since the charging system is appropriately set depending on the mobile communication network, the charging system may be different between roaming networks. For this reason, even when roaming between roaming networks, it is possible to prevent users from being charged for unintentional high communication charges, etc., by performing communication or the like without knowing the charging system of the roaming destination roaming network Can do.

  In addition, when the notification unit determines that the charging system has roamed from the roaming network to another roaming network with a lower amount or the same amount, it is preferable not to notify the user of the charging system of the roaming network that is the roaming destination.

  In this information notification device, when the mobile device roams from a roaming network to another roaming network with a lower or the same charging system as the roaming network, the charging system of the roaming network that is the roaming destination is not notified to the user. In other words, if the billing system is lower due to roaming or if the billing system does not change, there will be no particular disadvantage for the user even if the roaming network billing system is not notified. . Therefore, in such a case, by not reporting the billing system, it is possible to prevent the user operability of the mobile device from being degraded due to unnecessary notification.

  The notification means is a function that prompts the mobile device to restrict the function according to the direction of roaming when the mobile device communicates when the previous location information acquired by the location information acquisition device is different from the currently acquired location information. It is preferable to notify the user of restriction guidance.

  In this information notification device, when the previously acquired location information is different from the currently acquired location information, the function restriction guidance is notified to the user according to the roaming direction. For this reason, for example, when roaming from a roaming network to a home network, or when roaming between roaming networks with different charging systems, notification of appropriate function restriction guidance can be performed according to the roaming direction. In addition, since the function restriction guidance is notified at the time of communication of the mobile device, it is possible to prevent the user operability of the mobile device from being deteriorated by frequently notifying the function restriction guidance.

  In this case, when the notification unit determines that the roaming out has been performed from the home network to the roaming network, it is preferable to notify the user of a function restriction guide prompting the function restriction of the mobile device.

  In this information notification device, when the mobile device roams out from the home network to the roaming network, the function restriction guidance is notified to the user. That is, an automatic communication function or the like that automatically performs communication or the like without user operation may be set in the mobile device. For this reason, by alerting the user with the notification of the function restriction guidance, it is possible to prevent a communication fee or the like that is not intended by the user from being performed in the roaming network of the roaming destination, thereby preventing a high communication fee from being charged. it can.

  In addition, the notification means may notify the user of a function restriction guide for urging the function restriction of the mobile device when the roaming direction determination means determines that the roaming network has roamed to another roaming network with a higher charging system. preferable.

  In this information notification device, when a mobile device roams from a roaming network to another roaming network with a higher charging system than the roaming network, a function restriction guidance is notified to the user. In other words, when an automatic communication function or the like is set in the mobile device, communication or the like may be automatically performed without any user operation. For this reason, by alerting the user with the notification of the function restriction guidance, it is possible to prevent a communication fee or the like that is not intended by the user from being performed in the roaming network of the roaming destination, thereby preventing a high communication fee from being charged. it can.

  The information notifying apparatus according to the present invention has a function of canceling the function restriction when the roaming direction determining means determines that the roaming network has roamed in to the home network when the function restriction of the mobile device is performed in the roaming network. It is preferable to further include a restriction releasing unit.

  In this information notification device, when the mobile device has been restricted to a function such as an automatic communication function in the roaming network, when the mobile device roams into the home network from the roaming network, the function restriction is released. That is, the billing system for the home network is set to be lower than the roaming network, and the user is aware of the billing system for the home network. For this reason, in the home network, even if communication or the like is performed by the automatic communication function of the mobile device, there is no disadvantage to the user. It will be suitable. Therefore, when the mobile device roams into the home network, the user operability of the mobile device can be improved by releasing the function restriction.

  A billing system notification method according to the present invention is an information notification method for notifying a user of a billing system of a mobile communication network in which a mobile device is located. Determine the roaming direction based on the charging system acquisition step for acquiring the charging system of the mobile communication network in which the mobile device is located, and the previously acquired location information and the currently acquired location information in the location information acquisition step Notification step for notifying the user of information corresponding to the roaming direction when the mobile device communicates when the roaming direction determination step and the previously acquired location information in the location information acquisition step differ from the currently acquired location information. It is characterized by having.

  In the information notification method according to the present invention, if the previously acquired location information is different from the currently acquired location information, the roaming direction is determined, and information according to the roaming direction is notified to the user. Therefore, for example, when roaming from a roaming network to a home network, or when roaming between roaming networks with different charging systems, it is possible to notify the user of appropriate information according to the roaming direction, and user operability Can be improved.

  Hereinafter, embodiments of an information notification device, an information notification method, and an information notification system according to the present invention will be described with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the same element and the overlapping description is abbreviate | omitted.

  FIG. 1 is a network configuration diagram to which an information notification system 1 according to an embodiment of the present invention is applied.

  As shown in FIG. 1, the information notification system 1 is constructed in a network in which a plurality of mobile communication networks are connected via an international communication network. The information notification system 1 includes a server 2 provided in each mobile communication network and a mobile device 3 capable of roaming between mobile communication networks. Of the plurality of mobile communication networks, the mobile communication network of the communication company with which the user has a contract is the home network, and the mobile communication network other than the home network is the roaming network.

  The server 2 performs communication control of the mobile device 3 and roaming control of the mobile device 3 in each mobile communication network, and is configured by, for example, an HLR (Home Location Register). The server 2 registers the location of the mobile device 3 located in its own network, and performs roaming control of the mobile device 3. The server 2 holds network setting information such as a charging system in the mobile communication network.

  FIG. 2 is a diagram illustrating a functional configuration of the server, and FIG. 3 is a diagram illustrating a hardware configuration of the server. As shown in FIG. 2, the server 2 functionally includes a location registration unit 21 and a network setting information holding unit 22. As illustrated in FIG. 3, the server 2 physically includes a CPU 201, a ROM 202, a RAM 203, an auxiliary storage device 204, a communication module 205, an operation unit 206, and a display 207. . The functions described with reference to FIG. 2 operate the communication module 205 under the control of the CPU 201 by reading predetermined computer software onto the CPU 201 and the RAM 203 shown in FIG. This is realized by reading and writing data in 204.

  The location registration unit 21 registers the location of the mobile device 3 that is in the area. That is, in the case of the location registration of the mobile device 3 located in the home network, the location registration of the mobile device 3 is performed in the HLR of the own server 2. On the other hand, in the case of the location registration of the mobile device 3 located in the roaming network, the location registration of the mobile device 3 is performed by communicating with the server 2 provided in the home network of the mobile device 3. When the location registration unit 21 registers the location of the mobile device 3, the location registration unit 21 holds the location information of the mobile device 3 and transmits the location information to the mobile device 3.

  The network setting information holding unit 22 holds network setting information such as a charging system in the mobile communication network. Then, the network setting information holding unit 22 transmits this network setting information to the mobile device 3 and the server 2 provided in the home network of the mobile device 3.

  The mobile device 3 is a terminal such as a mobile phone owned by the user. The mobile device 3 can perform information communication such as transmission, reception, and packet to other mobile devices by communication control by the server 2. The mobile device 3 can be set with an automatic communication function for automatically connecting to a mobile communication network and performing communication or the like. This automatic communication function includes, for example, periodically connecting to the Internet, downloading stock price information, weather information, and the like and displaying them on a display. As another automatic communication function, for example, there is a function that periodically acquires a current position using a GPS (Global Positioning System) function and transmits the acquired current position to another device.

  Further, the mobile device 3 is provided with a roaming function. When the mobile device 3 moves between mobile communication networks, roaming between a plurality of mobile communication networks is possible by the roaming control by the server 2.

  FIG. 4 is a diagram illustrating a functional configuration of the mobile device. As shown in FIG. 4, the mobile device 3 functionally includes a location information acquisition unit 31, a network setting information acquisition unit 32, a roaming direction determination unit 33, a charging system notification unit 34, and a function restriction notification. A unit 35 and a function restriction release unit 36. The hardware configuration of the mobile device 3 is basically the same as that of the server 2 as shown in FIG. The functions described with reference to FIG. 4 operate the communication module 205 under the control of the CPU 201 by reading predetermined computer software onto the CPU 201 and the RAM 203 shown in FIG. This is realized by reading and writing data in 204.

  The location information acquisition unit 31 registers the location of the mobile device 3 and acquires location information of the mobile device 3 from the server 2 installed in the mobile communication network in which the mobile device 3 is present. Then, the location information acquisition unit 31 holds the acquired location information.

  The network setting information acquisition unit 32 acquires network setting information of a mobile communication network in which the mobile device 3 is located. The network setting information may be acquired from the server 2 provided in the mobile communication network in which the mobile device 3 performs location registration, or from the server 2 provided in the home network of the mobile device 3. It may be acquired, or may be registered in advance when the mobile device 3 is shipped. Then, the location information acquisition unit 31 holds the acquired location information.

  The roaming direction determination unit 33 determines the roaming direction of the mobile device 3. That is, the roaming direction determination unit 33 determines the roaming direction of the mobile device 3 by comparing the area information acquired last time in the area information acquisition unit 31 with the area information acquired this time. Note that the roaming direction of the mobile device 3 includes roaming out from the home network to the roaming network, roaming in from the roaming network to the home network, and roaming from the roaming network to another roaming network.

  The charging system notification unit 34 notifies the user of the charging system of the mobile communication network in which the mobile device 3 is located, according to the roaming direction of the mobile device 3. That is, the billing system notification unit 34 compares the area information acquired last time in the area information acquisition unit 31 with the area information acquired this time. Then, when the compared location information is different, the charging system notification unit 34 extracts the charging system from the network setting information acquired by the network setting information acquisition unit 32, and responds to the roaming direction determined by the roaming direction determination unit 33. Thus, the charging system of the mobile communication network in which the mobile device 3 is located is notified to the user. The network setting information is notified to the user when the mobile device 3 communicates. Note that the notification means to the user is performed by display on the display 207 or announcement (voice output) from a speaker (not shown).

  The manner of notifying the network setting information according to the roaming direction will be specifically described. In the case of roaming out from the home network to the roaming network, the charging system of the roaming network that is the roaming destination is notified to the user. In the case of roaming in from the roaming network to the home network, the charging system of the home network that is the roaming destination is not notified to the user. When roaming from a roaming network to another roaming network with a higher charging system, the user is notified of the charging system of the roaming network that is the roaming destination. When the roaming network roams to another roaming network with the same amount, the charging system of the roaming network that is the roaming destination is not notified to the user. When roaming from a roaming network to another roaming network with a lower charging system, the user is not notified of the charging system of the roaming network that is the roaming destination.

  The function restriction notifying unit 35 notifies the user of function restriction guidance that prompts the restriction setting of the automatic communication function of the mobile device 3 according to the roaming direction of the mobile device 3. That is, the function restriction notifying unit 35 compares the area information acquired last time in the area information acquiring unit 31 with the area information acquired this time. Then, when the compared location information is different, the function restriction notifying unit 35 notifies the user of function restriction guidance according to the roaming direction determined by the roaming direction determining unit 33. The function restriction guidance is notified to the user when the mobile device 3 communicates. Note that the notification means to the user is performed by display on the display 207 or announcement (voice output) from a speaker (not shown).

  A mode of notification of the function restriction guidance according to the roaming direction will be specifically described. In the case of roaming out from the home network to the roaming network, the function restriction guidance is notified to the user. In the case of roaming in from the roaming network to the home network, the function restriction guidance is not notified to the user. When roaming from a roaming network to another roaming network with a higher billing system, the function restriction guidance is notified to the user. When the charging system roams from the roaming network to another roaming network of the same amount, the function restriction guidance is not notified to the user. When roaming from a roaming network to another roaming network with a lower billing system, the function restriction guidance is not notified to the user.

  If the automatic communication function of the mobile device 3 is set to be restricted, the function restriction releasing unit 36 is to release the restriction setting in a predetermined case. The automatic communication function of the mobile device 3 automatically communicates regardless of the user's operation. Therefore, when the mobile device 3 is located in the roaming network, this automatic communication function restriction is set. There is a case. Therefore, when the automatic communication function is set to be restricted in this manner, the function restriction releasing unit 36 releases the restriction setting when the roaming direction determining unit 33 determines that the roaming network has roamed in to the home network. The function restriction release unit 36 maintains various setting states without releasing the restriction setting except when the roaming direction determination unit 33 determines that the roaming network has roamed into the home network.

  Next, the operation of the information notification system 1 according to the present embodiment will be described with reference to FIGS. FIG. 5 is a sequence diagram for explaining the processing operation of the information notification system 1. FIG. 6 shows the difference in processing operation according to the roaming direction when roaming between the home network and the roaming network. FIG. 7 is a diagram for explaining the difference in processing operation according to the roaming direction when roaming between roaming networks.

  First, with reference to the sequence diagram of FIG. 5, a case will be described as an example where the mobile device 3 roams out from the home network to the roaming network and then roams in from the roaming network to the home network.

  As shown in FIG. 5, when the mobile device 3 is located in the home network, the mobile device 3 communicates with the server 2a provided in the home network to register the location of the mobile device 3 (step S1). At this time, the location information and network setting information are transmitted from the server 2a to the mobile device 3, and the mobile device 3 acquires the location information and network setting information. When the mobile device 3 holds network setting information for the home network in advance, it is not necessary to acquire the network setting information for the home network in step S1.

  Next, the mobile device 3 changes the setting information of the mobile device 3 based on the location information and network setting information acquired from the server 2a (step S2).

  Next, when the mobile device 3 moves from the home network to the roaming network, the mobile device 3 communicates with the server 2b set in the roaming network and registers the location of the mobile device 3 (step S3). At this time, the location information and network setting information are transmitted from the server 2b to the mobile device 3, and the mobile device 3 acquires the location information and network setting information. When the mobile device 3 holds network setting information for the roaming network in advance, it is not necessary to acquire the network setting information for the roaming network in step S3.

  Next, the mobile device 3 changes the setting information of the mobile device 3 based on the location information and network setting information acquired from the server 2b (step S4).

  Then, the mobile device 3 compares the location information acquired in step S1 (the previously acquired location information) with the location information acquired in step S3 (the location information acquired this time). 3 is determined (step S5). In this case, the roaming direction is roaming out from the home network to the roaming network.

  Next, the mobile device 3 determines that the location information acquired in step S1 is different from the location information acquired in step S3 and that it is roaming out from the home network to the roaming network in step S5. The charging system is extracted from the network setting information of the roaming network, and this charging system is notified to the user (step S6).

  In addition, the mobile device 3 notifies the user of function restriction guidance during communication (step S7). In addition, the user performs restriction setting of the automatic communication function as necessary by receiving notification of the charging system and function restriction guidance.

  Thereafter, when the mobile device 3 moves from the roaming network to the home network, the mobile device 3 communicates with the server 2a provided in the home network and registers the location of the mobile device 3 (step S8). At this time, similarly to step S1, the location information and network setting information are transmitted from the server 2a to the mobile device 3, and the mobile device 3 acquires the location information and network setting information. Since the mobile device 3 has already acquired the network setting information of the home network in step S1, it is not necessary to acquire the network setting information in step S8. However, if the home network setting information has been changed between step S1 and step S8, the home network setting information is acquired from the server 2a in step S8.

  Next, the mobile device 3 changes the setting information of the mobile device 3 based on the location information and network setting information acquired from the server 2a (step S9).

  Then, the mobile device 3 compares the location information acquired in step S3 (the location information acquired last time) with the location information acquired in step S8 (the location information acquired this time). 3 is determined (step S10). In this case, the roaming direction is roaming in from the roaming network to the home network.

  At this time, since the mobile device 3 determines in step S10 that the roaming-in is from the roaming network to the home network, the mobile network 3 does not notify the charging system of the home network to the user (step S11).

  Then, when the user has performed the restriction setting of the automatic communication function upon receiving the notification in step S7, the mobile device 3 cancels the restriction setting of the automatic communication function during communication (step S12).

  Next, the difference in processing operation according to the roaming direction will be specifically described.

  First, a case where roaming is performed between the home network and the roaming network will be described with reference to FIG.

  When the mobile device 3 roams out from the home network to the roaming network (see arrow T1), the mobile device 3 notifies the user of the roaming destination billing system and function restriction guidance to the effect that the mobile device 3 has roamed out.

  On the other hand, when the mobile device 3 roams in from the roaming network to the home network (see arrow T2), the mobile device 3 notifies the user that it has roamed in, but the billing system and function restriction guidance for the home network that is the roaming destination Does not notify the user. Then, in the roaming network, when the automatic communication function is restricted to the mobile device 3, this restriction setting is released.

  Next, a case where roaming is performed between roaming networks will be described with reference to FIG.

  As shown in FIG. 7, when the mobile device 3 roams from the roaming network A to the roaming network B, the mobile device 3 first determines the charging system of the roaming network A and the charging system of the roaming network B from the acquired network setting information. And compare.

  If it is determined that the charging system of the roaming network B is more expensive than the roaming network A, the mobile device 3 notifies the user of the roaming-out charging system and function restriction guidance to the effect that the roaming is out. In the roaming network A, even if the mobile device 3 is restricted to the automatic communication function, this restriction setting is maintained. However, this restriction setting can be canceled by the user.

  If it is determined that the charging systems of the roaming network A and the roaming network B are the same amount, the mobile device 3 notifies the user only that the roaming network A has roamed to the roaming network B. The charging system and function restriction guidance are not notified to the user. In the roaming network A, even if the mobile device 3 is restricted to the automatic communication function, this restriction setting is maintained. However, this restriction setting can be canceled by the user.

  If it is determined that the charging system of the roaming network B is lower than the roaming network A, the mobile device 3 notifies the user that the roaming network A has roamed to the roaming network B. The charging system and function restriction guidance are not notified to the user. In the roaming network A, even if the mobile device 3 is restricted to the automatic communication function, this restriction setting is maintained. However, this restriction setting can be canceled by the user.

  As described above, in the present embodiment, if the previously acquired location information is different from the currently acquired location information, the roaming direction is determined, and information according to the roaming direction is notified to the user. For this reason, the user can be notified of appropriate information according to the roaming direction, and the user operability of the mobile device 3 can be improved.

  Further, in the present embodiment, when the previously acquired location information is different from the currently acquired location information, the charging system of the mobile communication network that is located is notified to the user according to the roaming direction. For this reason, notification of an appropriate billing system can be performed according to the roaming direction, and the user operability of the mobile device 3 can be improved. In addition, since the accounting system is notified when the mobile device 3 communicates, it is possible to prevent the user operability of the mobile device 3 from being deteriorated due to frequent notification of the accounting system.

  In the present embodiment, when the mobile device 3 roams out from the home network to the roaming network, the charging system of the roaming network that is the roaming destination is notified to the user. In other words, in general, the charging system is set to be lower in the home network with which the user is contracted, whereas the charging system is set to be higher in the roaming network than in the home network. For this reason, it is possible to prevent the user from being charged for an unintended high communication fee by performing communication or the like without knowing the charging system of the roaming network that is the roaming destination.

  In the present embodiment, when the mobile device 3 roams in from the roaming network to the home network, the charging system of the home network that is the roaming destination is not notified to the user. That is, in general, the charging system is set to be lower for the home network with which the user is contracted than the roaming network, and the user is aware of the charging system for the home network. For this reason, when roaming in from the roaming network to the home network, there is no particular disadvantage to the user without notifying the charging system of the home network. Therefore, in such a case, by not notifying the charging system, it is possible to prevent the user operability of the mobile device 3 from being deteriorated due to unnecessary notification.

  Further, in this embodiment, when the mobile device 3 roams from the roaming network to another roaming network that is more expensive than the roaming network, the charging system of the roaming network that is the roaming destination is notified to the user. That is, since the charging system is appropriately set depending on the mobile communication network, the charging system may be different between roaming networks. For this reason, even when roaming between roaming networks, it is possible to prevent users from being charged for unintended high communication charges, etc., by performing communication or the like without knowing the charging system of the roaming network that is the roaming destination be able to.

  Further, in this embodiment, when the mobile device 3 roams from the roaming network to another roaming network with a lower charging system or the same amount as the roaming network, the charging system of the roaming network that is the roaming destination is not notified to the user. In other words, if the billing system is lower due to roaming or if the billing system does not change, there will be no particular disadvantage for the user even if the roaming network billing system is not notified. . Therefore, in such a case, by not notifying the charging system, it is possible to prevent the user operability of the mobile device 3 from being deteriorated due to unnecessary notification.

  In the present embodiment, if the previously acquired area information is different from the area information acquired this time, the function restriction guidance is notified to the user according to the roaming direction. For this reason, notification of an appropriate function restriction guide can be performed according to the roaming direction. Moreover, since the function restriction guidance is notified at the time of communication of the mobile device, it is possible to prevent the user operability of the mobile device 3 from being deteriorated by frequently notifying the function restriction guidance.

  In this case, when the mobile device 3 roams out from the home network to the roaming network, the function restriction guidance is notified to the user. That is, the mobile device 3 may be set with an automatic communication function or the like in which communication or the like is automatically performed without user operation. For this reason, by alerting the user with the function restriction guidance, it is possible to prevent a high communication fee or the like from being charged due to communication or the like not intended by the user in the roaming destination roaming network.

  In addition, when the mobile device 3 roams from the roaming network to another roaming network that is more expensive than the roaming network, the function restriction guidance is notified to the user. That is, when the automatic communication function is set in the mobile device 3, communication or the like is automatically performed without any user operation. For this reason, even when roaming between roaming networks, alerting the user with the function restriction guidance causes unintended communication in the roaming destination roaming network, etc., resulting in high communication charges. Can be prevented.

  In this embodiment, when the restriction setting of the automatic communication function of the mobile device 3 is performed in the roaming network, when the mobile device 3 roams in from the roaming network to the home network, the restriction setting is canceled. That is, the billing system for the home network is set to be lower than the roaming network, and the user is aware of the billing system for the home network. For this reason, in the home network, even if communication or the like is performed by the automatic communication function of the mobile device 3, there is no disadvantage for the user. It will meet your wishes. Therefore, when the mobile device 3 roams into the home network, the user operability of the mobile device 3 can be improved by releasing the restriction setting of the automatic communication function.

  In the present embodiment, the mobile device 3 is provided with a location information acquisition unit 31 and a network setting information acquisition unit 32. For this reason, since the mobile device 3 holds the location information and the network setting information (charging system), the mobile device 3 can determine the roaming direction without communicating with the home network. In addition, notification of function restriction guidance and release of restriction settings can be performed. For this reason, the above processing can be performed even when an incoming call is made in a roaming network as in the case of optical routing.

As mentioned above, although this invention was concretely demonstrated based on the embodiment, this invention is not limited to the said embodiment. For example, in the above-described embodiment, the network setting information has been described only for the accounting system to notify the user, but other setting information may be notified to the user.
In addition, the notification of the billing system and the function setting guidance has been described as being performed at the time of communication of the mobile device, but may be notified at any other timing.

  In addition, when the mobile device 3 roams in from the roaming network to the home network, the function control release unit 36 has been described as releasing the restriction setting of the automatic communication function. For example, the function restriction release unit 36 temporarily The user may be notified of guidance for canceling the restriction setting of the communication function. Then, after the user receives this guidance and performs a predetermined operation, the restriction setting may be canceled.
