Description

  The present invention relates to a wireless communication device, system, method, and program for switching and using subscriber information.

  To connect a wireless communication device to a mobile network, first, a contract is made for a communication service of a communication carrier, and a SIM (Subscriber Identity Module) card in which subscriber information is recorded is issued. Then, by inserting and using the SIM card in the wireless communication device, the wireless communication device can be connected to the mobile network.

  The SIM is a subscriber authentication module used by a wireless communication device such as a smartphone or a mobile phone. As the subscriber authentication module, in addition to the SIM, there are a UIM (User Identity Module), a USIM (Universal Subscriber Identity Module), and the like, and hereinafter, all will be described as the SIM.

  When the communication carrier is an MVNO (Mobile Virtual Network Operator), the types of SIM cards include data communication only, with an SMS (Short Message Service) function, and with a call function. In a SIM card dedicated to data communication, since the telephone number is not included in the subscriber information, SMS transmission / reception and telephone conversation cannot be performed. On the other hand, in the SIM card with the SMS function and the call function, since the telephone number is included in the subscriber information, it is possible to perform SMS transmission / reception and call in addition to data communication.

  On the other hand, many communication services are contracted to reduce the communication speed when the accumulated data communication amount during a certain period exceeds a certain amount. Therefore, there is a demand for a user who frequently uses data communication to maintain high-speed communication by using a plurality of SIM cards and switching to another SIM card when the communication speed is reduced.

  In order to use a plurality of SIM cards, there is a method of using a wireless communication device capable of inserting a plurality of SIM cards, such as a dual SIM terminal, in addition to manually replacing the SIM cards. Also, there is a method in which a single SIM card has a plurality of pieces of subscriber information as in the method described in Patent Document 1.

JP 2015-180080 A

  However, in a wireless communication device capable of inserting a plurality of SIM cards, such as a dual SIM terminal, only one SIM card is used at a time, and the other SIM cards are not used. Therefore, when using a SIM card with an additional function and a SIM card without an additional function such as an SMS or a telephone call, the SIM card with the additional function cannot be used while the SIM card without the additional function is being used. That is, while using the SIM card without the additional function, it is not possible to perform transmission / reception of SMS or communication.

  Therefore, in such a wireless communication device, when the SIM card with the additional function is used up and the communication speed is reduced and the switching to the SIM card without the additional function is performed, SMS transmission / reception and a telephone call are performed. You can't do that.

  Further, even when a single SIM card has a plurality of pieces of subscriber information as in the method described in Patent Literature 1, only one piece of subscriber information is used at a time. Therefore, as in the case where a plurality of SIM cards are inserted, the additional function cannot be used while using the subscriber information for which the additional function cannot be used.

  An object of the present invention is to provide a wireless communication apparatus that can extend the time during which an additional function can be used when switching between subscriber information that can use an additional function and subscriber information that cannot be used. It is to provide a system, a method and a program.

  In order to solve the above-described problem, the wireless communication device of the present invention acquires first subscriber information in which additional functions can be used and second subscriber information in which the additional functions cannot be used. When there is communication data other than the additional function, the subscriber information acquiring unit selects the second subscriber information or the first subscriber information, and when there is no communication data, the first subscription And a first wireless communication unit that performs first wireless communication based on the selected subscriber information.

  Further, the wireless communication method of the present invention obtains first subscriber information in which the additional function can be used, and second subscriber information in which the additional function cannot be used. When there is communication data, the second subscriber information or the first subscriber information is selected, and when there is no communication data, the first subscriber information is selected, and the selected subscriber information is selected. The first wireless communication is performed based on the first wireless communication.

  Further, the wireless communication program of the present invention provides a computer with subscriber information for obtaining first subscriber information that can use an additional function and second subscriber information that cannot use the additional function. When there is communication data other than the acquisition function and the additional function, select the second subscriber information or the first subscriber information, and when there is no communication data, select the first subscriber information And a first wireless communication function for performing a first wireless communication based on the selected subscriber information.

  The wireless communication device, system, method, and program of the present invention can extend the time during which an additional function can be used when switching between subscriber information that can use an additional function and subscriber information that cannot be used. Will be possible.

[First embodiment]
A first embodiment of the present invention will be described.

  FIG. 1 shows a configuration example of a wireless communication device 10 of the present embodiment. The wireless communication device 10 according to the present embodiment includes a subscriber information acquisition unit 11, a selection unit 12, and a first wireless communication unit 13.

  The subscriber information acquisition unit 11 is a part that acquires first subscriber information in which additional functions can be used and second subscriber information in which additional functions cannot be used. The selection unit 12 is a unit that selects the second subscriber information or the first subscriber information when there is communication data other than the additional function, and selects the first subscriber information when there is no communication data. . The first wireless communication unit 13 performs a first wireless communication based on the selected subscriber information.

  By configuring the wireless communication device 10 in this manner, when there is no communication data other than the additional function, the wireless communication device 10 performs the first wireless communication based on the first subscriber information that can use the additional function. I do. Therefore, when there is no communication data other than the additional function, the additional function can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Next, FIG. 2 shows an example of the operation of the wireless communication device 10 of the present embodiment.

  When there is communication data other than the additional function (YES in step S101), the selection unit 12 of the wireless communication device 10 selects the second subscriber information or the first subscriber information (step S102). When there is no communication data (NO in step S101), the first subscriber information is selected (step S103). Then, the first wireless communication unit 13 performs the first wireless communication based on the selected subscriber information.

  By operating the wireless communication device 10 in this manner, the wireless communication device 10 can perform the first wireless communication based on the first subscriber information that can use the additional function when there is no communication data other than the additional function. I do. Therefore, when there is no communication data other than the additional function, the additional function can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  As described above, in the first embodiment of the present invention, when there is no communication data other than the additional function, the first wireless communication is performed based on the first subscriber information in which the additional function can be used. . For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

[Second embodiment]
Next, a second embodiment of the present invention will be described. In the present embodiment, the wireless communication device 10 of the first embodiment will be described more specifically.

  First, a configuration example of the wireless communication device 10 according to the present embodiment will be described with reference to FIG. The configuration example of the wireless communication device 10 is the same as that of the first embodiment.

  The wireless communication device 10 corresponds to a device that performs wireless communication by a WAN (Wide Area Network) such as a mobile network, such as a mobile phone, a smartphone, a mobile router, a home router, and a HEMS (Home Energy Management System).

  The subscriber information acquisition unit 11 is a part that acquires first subscriber information in which additional functions can be used and second subscriber information in which additional functions cannot be used. Specifically, the subscriber information acquisition unit 11 corresponds to a SIM card slot, and acquires subscriber information from a SIM card inserted into the SIM card slot.

  In the present embodiment, for the sake of simplicity, a case will be described in which the subscriber information acquisition unit 11 includes two SIM card slots. In the present embodiment, the first subscriber information is acquired from the first SIM card inserted into the first SIM card slot, and the second subscriber information is acquired from the second SIM card inserted into the second SIM card slot. Subscriber information shall be obtained. Note that it is also possible to acquire a plurality of pieces of subscriber information from a SIM card storing a plurality of pieces of subscriber information, and to acquire subscriber information from three or more SIM cards.

  Further, the first subscriber information is subscriber information of a SIM card that can use additional functions such as an SMS function and a call function in addition to data communication. The second subscriber information is the subscriber information of the SIM card without additional functions. In the present embodiment, an example in which the additional function is an SMS function will be described below.

  The selector 12 selects the second subscriber information or the first subscriber information when there is communication data other than the additional function, and selects the first subscriber information when there is no communication data other than the additional function. This is the part to do. The communication data other than the additional function is communication data of data communication transmitted and received by the first wireless communication unit 13 other than the additional function (SMS in the present embodiment). For example, transmission / reception data of a browser application and the like correspond.

  If there are a plurality of first subscriber information or second subscriber information, the selected first subscriber information (with additional function) or second subscriber information (with additional function) ) May be further selected. The selection method in that case is not described in the present embodiment.

  The first wireless communication unit 13 is a unit that performs the first wireless communication based on the subscriber information selected by the selection unit 12. That is, when the first subscriber information is selected, the first wireless communication is performed using the first SIM card, and when the second subscriber information is selected, the second SIM card is used. Perform first wireless communication.

  The first wireless communication specifically corresponds to communication by a WAN such as a mobile network. Examples of the WAN line include LTE (Long Term Evolution), 3G (Third Generation), WiMAX (Worldwide Interoperability for Microwave Access) (registered trademark), and the like.

  By configuring the wireless communication device 10 in this manner, when there is no communication data other than the additional function, the wireless communication device 10 performs the first wireless communication based on the first subscriber information that can use the additional function. I do. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. The function can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Next, an example of the operation of the wireless communication device 10 will be described with reference to FIG.

  When there is communication data other than the additional function (YES in step S101), the selection unit 12 of the wireless communication device 10 selects the second subscriber information or the first subscriber information (step S102). Then, the first wireless communication unit 13 performs the first wireless communication based on the selected subscriber information. At this time, if the first subscriber information is selected, the additional function can be used (SMS transmission / reception), but if the second subscriber information is selected, the additional function cannot be used.

  When there is no communication data other than the additional function (NO in step S101), the first subscriber information is selected (step S103). Then, the first wireless communication unit 13 performs the first wireless communication based on the first subscriber information. That is, SMS transmission / reception is performed using a SIM card with an SMS function.

  After the selection unit 12 selects the subscriber information, the process returns to step S101, and again selects the subscriber information based on the presence or absence of communication data other than the additional function. Therefore, if there is no communication data other than the additional function transmitted and received by the first wireless communication unit 13, the first subscriber information is selected.

  By operating the wireless communication device 10 in this manner, the wireless communication device 10 can perform the first wireless communication based on the first subscriber information that can use the additional function when there is no communication data other than the additional function. I do. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. The function can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  As described above, in the second embodiment of the present invention, similar to the first embodiment, when there is no communication data other than the additional function, the first subscriber information that can use the additional function is included in the first subscriber information. The first wireless communication is performed based on the first wireless communication. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

[Third embodiment]
Next, a third embodiment of the present invention will be described. This embodiment differs from the second embodiment in that a method of selecting the first user information or the second user information (step S102) when there is communication data other than the additional function is added. It is.

  First, FIG. 3 shows a configuration example of the wireless communication device 20 of the present embodiment. The wireless communication device 20 includes a subscriber information acquisition unit 11, a selection unit 22, a first wireless communication unit 13, and a monitor unit 24. The subscriber information acquisition unit 11 and the first wireless communication unit 13 are the same as those in the second embodiment, and thus the description is omitted.

  The monitoring unit 24 is a unit that monitors the communication status of the first wireless communication unit. In the present embodiment, a communication amount of data communication is used as a communication state.

  As in the first embodiment, the selector 22 selects the second subscriber information or the first subscriber information when there is communication data other than the additional function, and selects the first subscriber information when there is no communication data. This is a part for selecting subscriber information. In the present embodiment, when there is communication data other than the additional function, and when the communication status monitored by the monitor unit 24 satisfies a predetermined condition, the second subscriber information is selected and the communication status is set to a predetermined condition. If not, select the first subscriber information.

  As the predetermined condition, a condition that “the data communication amount of the first wireless communication based on the first subscriber information exceeds a predetermined communication amount” is used. According to this condition, when the data traffic using the SIM card with the additional function exceeds a predetermined traffic, the data communication is performed with the SIM card without the additional function. That is, first, data communication is performed using a SIM card with an additional function, and when the communication amount exceeds a predetermined amount, data communication is performed using a SIM card without an additional function.

  If the contract for the first subscriber information is a contract for reducing the communication speed when the cumulative data communication amount for a certain period exceeds the upper limit, the upper limit of the data communication amount that allows high-speed data communication as the predetermined communication amount It is better to set a value less than the value. By doing so, it is possible to switch to the second subscriber information before the communication speed of the first wireless communication based on the first subscriber information decreases, and to maintain high-speed data communication.

  By configuring the wireless communication device 20 in this manner, when there is no communication data other than the additional function, the wireless communication device 20 performs the first wireless communication based on the first subscriber information that can use the additional function. I do. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. Can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Further, in this embodiment, when the data traffic based on one subscriber information exceeds a predetermined traffic, data communication is performed with the other subscriber information. Therefore, high-speed data communication can be maintained even if the contracted service is a service in which the communication speed is reduced due to an increase in the amount of communication.

  Next, FIG. 4 shows an example of the operation of the wireless communication device 20.

  When there is communication data other than the additional function (YES in step S201), the selection unit 22 of the wireless communication device 20 checks whether the communication status satisfies a predetermined condition (step S202). In the present embodiment, a condition that “the data traffic of the first wireless communication based on the first subscriber information exceeds a predetermined traffic” is confirmed. Then, if a predetermined condition is satisfied, that is, if the communication amount exceeds a predetermined communication amount, the second subscriber information is selected (step S203). Then, the first wireless communication unit 13 performs the first wireless communication based on the second subscriber information. That is, data communication is performed using a SIM card without the SMS function.

  When the communication condition does not satisfy the predetermined condition in step S202, that is, when the communication condition does not exceed the predetermined communication amount, the first subscriber information is selected (step S204). Then, the first wireless communication unit 13 performs the first wireless communication based on the first subscriber information. That is, data communication and SMS transmission / reception are performed using a SIM card with an SMS function.

  If there is no communication data (NO in step S201), the first subscriber information is selected (step S204). Then, the first wireless communication unit 13 performs the first wireless communication based on the first subscriber information. That is, SMS transmission / reception is performed using a SIM card with an SMS function.

  After the selection unit 22 selects the subscriber information, the process returns to step S201, and the selection of the subscriber information is performed again according to the presence or absence of communication data other than the additional function. Therefore, if there is no communication data other than the additional function transmitted and received by the first wireless communication unit 13, the first subscriber information is selected.

  By operating the wireless communication device 20 in this manner, when there is no communication data other than the additional function, the wireless communication device 20 performs the first wireless communication based on the first subscriber information that can use the additional function. I do. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. Can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Further, in this embodiment, when the data traffic based on one subscriber information exceeds a predetermined traffic, data communication is performed with the other subscriber information. Therefore, high-speed data communication can be maintained even if the contracted service is a service in which the communication speed is reduced due to an increase in the amount of communication.

  In the above description, as an example of the predetermined condition, the condition that “the data communication amount of the first wireless communication based on the first subscriber information exceeds the predetermined communication amount” is given. Under this condition, the SIM card with the additional function is used until the data traffic using the SIM card with the additional function exceeds the predetermined traffic. When the data traffic exceeds the predetermined traffic, the additional Data communication is performed using a SIM card without a function.

  As another example, a condition that “the data traffic of the first wireless communication based on the second subscriber information is equal to or less than a predetermined traffic” can be used as the predetermined condition. In this case, at the time of data communication, first, data communication is performed using a SIM card without an additional function, and when the data communication amount exceeds a predetermined communication amount, data communication is performed using a SIM card with an additional function. Become. Even under this condition, it is possible to switch to the other SIM card before the data communication speed of one SIM card decreases, so that high-speed data communication can be maintained. In the case of this condition, the SIM card without the additional function is used in the data communication until the predetermined condition is not satisfied, so that the time during which the additional function can be used is reduced. However, if the data communication fee of the SIM card without the additional function is lower, the use of the SIM card without the additional function first has the effect of reducing the total communication fee. Therefore, it is possible for the user to select which SIM card is used first.

  As described above, in the third embodiment of the present invention, similar to the first and second embodiments, when there is no communication data other than the additional function, the first subscription that can use the additional function is performed. Wireless communication is performed based on the party information. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. Can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Further, in this embodiment, when the data traffic based on one subscriber information exceeds a predetermined traffic, data communication is performed with the other subscriber information. Therefore, even if the contracted service is a service that reduces the communication speed due to an increase in the amount of communication, high-speed data communication can be maintained.

[Fourth embodiment]
Next, a fourth embodiment of the present invention will be described. This embodiment is a modification of the third embodiment in which the data communication amount and the required communication speed are used as the communication status.

  First, a configuration example of the wireless communication device 20 according to the present embodiment will be described with reference to FIG. The configuration example of the wireless communication device 20 of the present embodiment is the same as that of the third embodiment. The subscriber information acquisition unit 11 and the first wireless communication unit 13 are the same as those in the second embodiment, and thus the description is omitted.

  The monitoring unit 24 is a unit that monitors the communication status of the first wireless communication unit, as in the third embodiment. In the present embodiment, the required communication speed is used as the communication status in addition to the communication amount of data communication. The required communication speed is a communication speed required for transmitting and receiving data communication.

  As in the third embodiment, the selection unit 22 selects the subscriber information based on the presence or absence of communication data other than the additional function and whether the communication status satisfies a predetermined condition.

  As the predetermined condition, in the present embodiment, in addition to the first condition that “the data communication amount of the first wireless communication based on the first subscriber information exceeds a predetermined communication amount”, The second condition that the data communication speed is equal to or higher than a specified value is used. The selection unit 22 selects the second subscriber information when both the first condition and the second condition are satisfied, and selects the first subscriber information when either one is not satisfied.

  According to the first condition, at the time of data communication, data communication is first performed using a SIM card with an additional function, and when the communication amount exceeds a predetermined communication amount, data communication is performed using a SIM card without an additional function. According to the second condition, when the required data communication speed is equal to or higher than a specified value, data communication is performed using a SIM card without additional functions, and when the required data communication speed is less than the specified value, data communication is performed using a SIM card with additional functions. become.

  Therefore, when the first condition is satisfied but the second condition is not satisfied, that is, when the required data communication speed is less than the specified value even when the communication amount exceeds a predetermined amount of communication, the SIM card with the additional function performs data communication. Will be done. In other words, even when the high-speed data communication volume of the SIM card with the additional function is used up and the speed is limited to a low speed, if the data communication speed is low and there is no problem, the data communication is continued with the SIM card with the additional function as it is. Will do. For example, when performing low-speed and long-time data communication such as a net radio, there is no problem with a low-speed data communication speed. Therefore, data communication is continued with a SIM card with an additional function. Therefore, the prescribed value of the required data communication speed is preferably equal to or lower than the communication speed when the communication speed is limited to a low speed.

  In this way, even when the high-speed data communication amount is used up, it is possible to suppress the switching to the SIM card without the additional function when the low-speed operation is sufficient, and it is possible to extend the time during which the additional function can be used. Become. The same effect can be obtained even when the first condition is “the data traffic of the first wireless communication based on the second subscriber information is equal to or less than a predetermined traffic”.

  By configuring the wireless communication device 20 in this manner, when there is no communication data other than the additional function, the wireless communication device 20 performs the first wireless communication based on the first subscriber information that can use the additional function. I do. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. Can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Further, in this embodiment, when the data traffic based on one subscriber information exceeds a predetermined traffic, data communication is performed with the other subscriber information. Therefore, high-speed data communication can be maintained even if the contracted service is a service in which the communication speed is reduced due to an increase in the amount of communication.

  Further, in the present embodiment, when the required data communication speed is lower than the specified value, the first subscriber information which can use the additional function is selected. Therefore, when the communication speed of the first wireless communication based on the first subscriber information is limited to a low speed, if the low speed does not matter, the additional function can be used by selecting the first subscriber information Time can be further extended.

  Next, FIG. 5 shows an example of the operation of the wireless communication device 20 of the present embodiment. The difference from FIG. 4 is that step S202 in FIG. 4 is replaced with steps S302 and S303 in FIG.

  When there is communication data other than the additional function (YES in step S301), the selection unit 22 of the wireless communication device 20 checks whether the communication condition satisfies the first condition (step S302). In the present embodiment, the first condition that “the data traffic of the first wireless communication based on the first subscriber information exceeds a predetermined traffic” is confirmed. If the first condition is satisfied, that is, if the traffic exceeds a predetermined communication amount, it is further confirmed whether or not the second condition is satisfied (step S303). In the present embodiment, the second condition that “the required data communication speed is equal to or higher than a specified value” is confirmed. If the second condition is satisfied, the second subscriber information is selected (step S304). Then, the first wireless communication unit 13 performs the first wireless communication based on the second subscriber information. That is, data communication is performed using a SIM card without the SMS function.

  If the communication condition does not satisfy the predetermined condition in steps S302 and S303, the first subscriber information is selected (step S305). Then, the first wireless communication unit 13 performs the first wireless communication based on the first subscriber information. That is, data communication and SMS transmission / reception are performed using a SIM card with an SMS function.

  When there is no communication data (NO in step S301), the first subscriber information is selected (step S305). Then, the first wireless communication unit 13 performs the first wireless communication based on the first subscriber information. That is, SMS transmission / reception is performed using a SIM card with an SMS function.

  After the selection unit 22 selects the subscriber information, the process returns to step S301, and the selection of the subscriber information is performed again according to the presence or absence of communication data other than the additional function. Therefore, if there is no communication data other than the additional function transmitted and received by the first wireless communication unit 13, the first subscriber information is selected.

  By operating the wireless communication device 20 in this manner, the wireless communication device 20 can use the additional function when switching between subscriber information that can use the additional function and subscriber information that cannot use the additional function. It is possible to extend the time.

  As described above, in the fourth embodiment of the present invention, similar to the first to third embodiments, when there is no communication data other than the additional function, the first subscription that can use the additional function is performed. Wireless communication is performed based on the party information. Therefore, even if data communication is performed based on the second subscriber information in which the additional function cannot be used, the data is returned to the first subscriber information in which the additional function can be used after the data communication is completed. Can be used. For this reason, it is possible to extend the time during which the additional function can be used when switching between the subscriber information that can use the additional function and the subscriber information that cannot use the additional function.

  Further, in this embodiment, when the data traffic based on one subscriber information exceeds a predetermined traffic, data communication is performed with the other subscriber information. Therefore, high-speed data communication can be maintained even if the contracted service is a service in which the communication speed is reduced due to an increase in the amount of communication.

  Further, in the present embodiment, when the required data communication speed is lower than the specified value, the first subscriber information which can use the additional function is selected. Therefore, when the communication speed of the first wireless communication based on the first subscriber information is limited to a low speed, if the low speed does not matter, the additional function can be used by selecting the first subscriber information Time can be further extended.

[Fifth embodiment]
Next, a fifth embodiment of the present invention will be described. In the present embodiment, a case will be described in which a wireless communication device relays communication data between a WAN and a wireless client device.

  FIG. 6 shows a configuration example of the wireless communication device 30 of the present embodiment. FIG. 7 shows a configuration example of the wireless slave device 50 of the present embodiment.

  In FIG. 6, a second wireless communication unit 35 and a data exchange unit 36 are added to the configuration example (FIG. 1) of the wireless communication device 10 of the first and second embodiments. As shown in FIG. 8, a second wireless communication unit 35 and a data exchange unit 36 can be added to the configuration example (FIG. 3) of the wireless communication device 20 of the third or fourth embodiment. The subscriber information acquisition unit 11, the selection unit 12, and the first wireless communication unit 13 are the same as those in the second embodiment, and thus the description is omitted.

  The second wireless communication unit 35 is a part that performs the second wireless communication with the wireless slave device 50. The second wireless communication specifically corresponds to communication by a LAN (Local Area Network). A wireless LAN, Bluetooth (registered trademark), or the like corresponds to the LAN line.
