Description

  The present disclosure relates to a communication relay device, a wireless communication system, a control method and control program for the communication relay device, and more particularly, to a communication relay device relaying communication with a wireless information terminal, a wireless communication system, and a control method and control for the communication relay device. About the program.

  In recent years, a wireless information terminal capable of wireless communication downloads various applications from a server that distributes the applications and executes them after installation. Also, for each installed application, updated versions are released at various timings. Then, the wireless information terminal downloads the updated version of the corresponding application from the server by an operation by the user, an application for updating the application, or the like.

  Patent Document 1 discloses a technique related to a system that supports update of an application in a so-called information home appliance. In the system according to Patent Document 1, a home server, and a plurality of home appliances and home terminals are connected by a wireless home network. The home server connects a home network and an external network, and has a gateway function and a router function. An application server that distributes an updated version of the application is connected to the external network side. At this time, the home terminal collects version information of each application installed in each home appliance, and inquires of the application server whether or not the latest version of each application exists. Then, when the latest version exists, the home terminal downloads the latest version of the corresponding application from the application server, transfers it to the corresponding home electric appliance, and causes the version of the application to be upgraded.

  Here, wireless information terminals such as smartphones and tablet terminals often support a plurality of wireless communication methods such as mobile communication and wireless LAN (Local Area Network) communication. Mobile communication refers to communication using a mobile phone line such as LTE (Long Term Evolution) or 3G. The wireless LAN communication refers to communication using a wireless LAN line such as WiFi (Wireless Fidelity) (registered trademark). Then, in the wireless information terminal, it often takes a long time to download the updated version of the installed application. Therefore, it is desirable to use wireless LAN communication capable of more stable wireless communication for downloading the updated version of the application. Therefore, an application management application that installs and updates an application in the wireless information terminal can select, for example, the following three types of settings as application update settings. For example, there are three types: "do not update automatically", "always update automatically", and "automatically update only when connected to WiFi". As an initial setting of the application update setting, “automatic update only when connected to WiFi” is performed, so that the application can be automatically updated in a more stable communication environment.

JP, 2005-107737, A

  However, when the wireless information terminal is connected to a wireless relay device such as a mobile router and the application update setting is the initial setting, the application is automatically updated without the user's intention. There is a point. First, the mobile router can relay communication between the information terminal and the external network by connecting the wireless information terminal with the wireless LAN line and connecting the external network with the mobile communication line. Then, since the information terminal is connected to the mobile router by the wireless LAN, the application management application in the information terminal determines that the application can be automatically updated in the case of the initial setting. Therefore, the mobile router may download the updated version from the external network via the mobile communication line. Therefore, although the user does not intend to download a large amount of data via the mobile communication line, an updated version of the application, which is a large amount of data over a long period of time, is eventually obtained via the mobile communication line. It may be downloaded. In particular, when communication is unstable, the probability that automatic updating will fail increases.

In the drawings, the same or corresponding elements are denoted by the same reference numerals, and for the sake of clarity of the description, redundant description will be omitted as necessary.

Embodiment 1
FIG. 1 is a block diagram showing an overall configuration of a wireless communication system 1000 including a wireless information terminal 10 and a communication relay device 20 according to a first embodiment of the present invention. The wireless communication system 1000 includes a wireless information terminal 10, a communication relay device 20, and a communication device 40. Here, the wireless information terminal 10 and the communication relay device 20 are connected by the first wireless access method W1. The communication device 40 is an information processing device disposed on the external network 30. The communication relay device 20 and the external network 30 are connected by the second wireless access method W2. Therefore, the communication relay device 20 and the communication device 40 can communicate by the second wireless access method W2. Here, it is assumed that the first wireless access method W1 has a smaller amount of communication restriction than the second wireless access method W2. For example, the first wireless access method W1 is an access method by wireless LAN communication, and the second wireless access method W2 is an access method by mobile communication.

  The wireless information terminal 10 is an information terminal that communicates using the first wireless access method W1. The wireless information terminal 10 may be capable of communication also by the second wireless access method W2. The wireless information terminal 10 is, for example, a smartphone or a tablet terminal, but is not limited thereto. In the wireless information terminal 10, installed application software operates.

  The communication device 40 is an application management server that distributes the updated version of the application installed in the wireless information terminal 10. The communication device 40 is a server computer arranged on the Internet, for example.

  The external network 30 is a communication network including a mobile communication network and the Internet. Therefore, the external network 30 includes, for example, a gateway server that mediates the exchange between the mobile communication network and the Internet. The communication relay device 20 is connected to the mobile communication network of the external network 30 by the second wireless access method W2, and can communicate with the communication device 40 via the gateway server.

  The communication relay device 20 relays communication with the wireless information terminal 10 according to the first wireless access method W1 and communication with the communication device 40 according to the second wireless access method W2. The communication relay device 20 includes a first wireless communication unit 21, a second wireless communication unit 22, and a control unit 23. The first wireless communication unit 21 communicates with the wireless information terminal 10 by the first wireless access method W1. The second wireless communication unit 22 communicates with the communication device 40 by the second wireless access method W2. The control unit 23 relays communication between the wireless information terminal 10 and the communication device 40 using the first wireless communication unit 21 and the second wireless communication unit 22. Here, when the message received from the wireless information terminal 10 is an application update request in the wireless information terminal 10, the control unit 23 discards the message and updates the application to the wireless information terminal 10. Reply that it has stopped.

  FIG. 2 is a flowchart showing a flow of a control method of the communication relay apparatus according to the first embodiment of the present invention. First, the first wireless communication unit 21 of the communication relay device 20 connects with the wireless information terminal 10 by the first wireless access method W1 (S11). For example, when the first wireless communication unit 21 receives a connection request from the wireless information terminal 10 using the first wireless access method W1, the first wireless communication unit 21 establishes a connection with the wireless information terminal 10 using the first wireless access method W1. Do.

  Next, the communication relay device 20 monitors a message from the wireless information terminal 10 (S12). When the message from the wireless information terminal 10 is received, the control unit 23 of the communication relay device 20 determines whether the received message is an application update request (S13). If it is determined that the received message is an application update request, the control unit 23 discards the received message (S14). Then, the control unit 23 uses the first wireless communication unit 21 to return a notification of the application update stop to the wireless information terminal 10 (S15). On the other hand, if it is determined in step S13 that the received message is not an application update request, the control unit 23 uses the second wireless communication unit 22 to transmit the received message to the external network 30 using the second wireless access method W2. Transmit on the side (S16).

  Here, the wireless information terminal 10 tends to have an illusion that the application can be stably updated because the directly connected wireless access method is the first wireless access method W1 having relatively high communication stability. is there. On the other hand, the communication relay device 20 is the second wireless access method W2 in which the wireless access method between itself and the external network 30 has relatively low communication stability. Therefore, the communication relay device 20 blocks the update request of the application, and sends a notification of the update stop to the wireless information terminal 10. Therefore, it is possible to avoid downloading an updated version of the application via the second wireless access method W2, which has relatively low communication stability compared to the first wireless access method W1. Then, the wireless information terminal 10 can subsequently download an updated version of the application by a wireless access method having higher communication stability than the second wireless access method W2. Therefore, automatic update of the application in the wireless information terminal 10 can be stably realized.

  In addition, the mobile communication line, which is an example of the second wireless access method W2, may generate a data communication charge depending on the line contract. Therefore, when this embodiment is not used, the wireless information terminal 10 is updated by the mobile communication line via the mobile router as a result when the wireless LAN terminal is connected to a general mobile router. I download the version of the application. In this case, a large amount of communication data is generated via the mobile communication line, packet usage is added, and a data communication charge is generated. On the other hand, in the present embodiment, it is possible to prevent a user from using a large capacity of the mobile communication line unexpectedly, and to reduce the data communication fee more inexpensively.

Second Embodiment
The second embodiment is an example of the first embodiment described above. That is, when the received message is autonomously transmitted by the wireless information terminal, the control unit according to the second embodiment determines that the request is for updating an application in the wireless information terminal. To do. Thereby, for example, it is possible to block automatic update from an application update application in the wireless information terminal. In other words, with respect to other communications due to user operations or the like in the wireless information terminal, it is possible to maintain the relay of communications with the external network, which is the original operation.

  In addition, the control unit acquires and holds a first list of applications installed in the wireless information terminal from the wireless information terminal using the first wireless communication unit. The control unit may determine that the received message is an update request for an application in the wireless information terminal when the received message is an acquisition request for the application in the first list. This makes it possible to accurately grasp that the download request for the installed application is an update request. Moreover, since the automatic update from the application for application update is for the applications included in the first list, it can be accurately grasped that it is transmitted autonomously.

  FIG. 3 is a block diagram showing a configuration of the wireless communication system 2000 according to the second embodiment of the present invention. The wireless communication system 2000 is an example of the wireless communication system 1000 described above. The wireless communication system 2000 includes a slave terminal 100, a mobile router 200, and an application management server 400. Here, the slave terminal 100 is an example of the wireless information terminal 10. The mobile router 200 is an example of the communication relay device 20. The communication network 300 is an example of the external network 30. The application management server 400 is an example of the communication device 40 and is an information processing device arranged on the communication network 300. The application management server 400 stores an updated version application 401 and an application 402 in an internal storage device (not shown). Here, the updated version application 401 is the latest version program in the application 152 described later. Further, it is assumed that the application 402 is not installed in the slave terminal 100. That is, the application 402 can be said to be a new application for the slave terminal 100. Upon receiving an application acquisition request via the communication network 300, the application management server 400 identifies an application corresponding to the acquisition request and distributes it to the request source.

  And the subunit | mobile_unit terminal 100 and the mobile router 200 are connected by the wireless LAN communication W11. In addition, the mobile router 200 and the communication network 300 are connected by LTE communication W21. Therefore, the mobile router 200 and the application management server 400 can communicate with each other by LTE communication W21. Here, the wireless LAN communication W11 is an example of the first wireless access method W1, and is, for example, WiFi. The LTE communication W21 is an example of the second radio access method W2, and 3G or the like may be used instead of LTE.

  The slave terminal 100 includes an LTE wireless unit 110, a wireless LAN communication unit 120, a modem unit 130, a CPU 140, and a storage unit 150. The LTE wireless unit 110 can be connected to the communication network 300 by the LTE method. The wireless LAN communication unit 120 can be connected to the mobile router 200 by the wireless LAN communication W11. In the description of the present embodiment, it is assumed that the slave terminal 100 is set to give priority to the wireless LAN communication W11.

  The modem unit 130 is a circuit that mutually converts an analog signal and a digital signal. That is, the modem unit 130 converts the LTE analog signal received by the LTE radio unit 110 into a digital signal and outputs the digital signal to the CPU 140. The modem unit 130 converts the wireless LAN analog signal received by the wireless LAN communication unit 120 into a digital signal and outputs the digital signal to the CPU 140. In addition, when the connection with the communication network 300 is established by the LTE wireless unit 110, the modem unit 130 converts the digital signal to be transmitted from the CPU 140 into an analog signal for LTE and transmits the analog signal to the outside by the LTE wireless unit 110. Do. In addition, when the wireless LAN communication unit 120 establishes connection with the mobile router 200, the modem unit 130 converts the digital signal to be transmitted from the CPU 140 into an analog signal for wireless LAN, and the wireless LAN communication unit 120 Send to the outside.

  The CPU 140 is a control circuit that controls each component of the slave terminal 100 and performs various processes. The storage unit 150 is a nonvolatile storage device that stores an application update list 151, an application 152, and the like. The application 152 is an application installed in the child device terminal 100. Note that the number of applications 152 is one or more. The application update list 151 is list information that lists the applications 152 installed in the slave terminal 100. FIG. 4 is a diagram showing an example of the application update list 151 according to the second embodiment of the present invention.

  Note that the storage unit 150 also stores an operating system, an application update application, and the like as a configuration (not shown). The application update application manages the application update list 151, receives an update notification from the server that distributes the updated version of each application for each application in the application update list 151, and autonomously issues an application update request. The CPU 140 reads the operating system and application 152 from the storage unit 150 and executes it. Thereby, the slave terminal 100 performs various processes in the application 152. Further, the CPU 140 reads an application update application from the storage unit 150 and executes it. As a result, the slave terminal 100 autonomously transmits an update request for the application 152 to the application management server 400. Then, when receiving the updated version application 401 from the application management server 400, the slave terminal 100 is installed. Thereby, the application 152 is updated.

  The mobile router 200 includes an LTE wireless unit 210, a wireless LAN communication unit 220, a modem unit 230, a CPU 240, and a storage unit 250. The LTE wireless unit 210 is an example of the second wireless communication unit 22, and can be connected to the communication network 300 by the LTE communication W21. The wireless LAN communication unit 220 is an example of the first wireless communication unit 21 and can be connected to the wireless LAN communication unit 120 of the slave terminal 100 through the wireless LAN communication W11. In the description of the present embodiment, it is assumed that at least the LTE radio unit 210 and the communication network 300 are already connected by the LTE communication W21.

  The modem unit 230 is a circuit that mutually converts an analog signal and a digital signal. That is, the modem unit 230 converts the LTE analog signal received by the LTE radio unit 210 into a digital signal and outputs the digital signal to the CPU 240. The modem unit 230 converts the wireless LAN analog signal received by the wireless LAN communication unit 220 into a digital signal and outputs the digital signal to the CPU 240. The modem unit 230 converts the digital signal to be transmitted to the WAN (Wide Area Network) received from the CPU 240 into an analog signal for LTE, and transmits the analog signal to the communication network 300 by the LTE radio unit 210. The modem unit 230 converts the digital signal to be transmitted to the LAN side received from the CPU 240 into an analog signal for wireless LAN, and transmits the analog signal to the slave terminal 100 by the wireless LAN communication unit 220.

  The CPU 240 is an example of the control unit 23, and is a control circuit that controls each component of the mobile router 200 to perform various processing. The storage unit 250 is a non-volatile storage device that stores the application update list 251 and the like. However, the storage unit 250 does not necessarily store the application update list 251. When the storage unit 250 does not store the application update list 251, the CPU 240 acquires the application update list 151 from the child device terminal 100 using the wireless LAN communication unit 220 and stores it in the storage unit 250.

  Note that the storage unit 250 also stores an operating system, an application update control program, and the like as a configuration (not shown). The application update control program is an example of a control program according to the present embodiment, and a control method of a communication relay apparatus described later is implemented. The CPU 240 reads the operating system and application update control program from the storage unit 250 and executes them. Thereby, the mobile router 200 implements a communication relay device control method described later.

  FIG. 5 is a flowchart showing the flow of a control method of the communication relay apparatus according to the second embodiment of the present invention. Here, it is assumed that the application update list 251 is not stored in the storage unit 250 in advance.

  First, the slave terminal 100 belongs to the mobile router 200 (S101). For example, when the wireless LAN communication unit 220 receives a connection request via the wireless LAN communication W11 from the wireless LAN communication unit 120, the wireless LAN communication unit 220 establishes a connection with the slave terminal 100 via the wireless LAN communication W11.

  Next, the mobile router 200 requests the application update list 151 from the slave terminal 100 (S102). That is, the CPU 240 transmits an acquisition request for the application update list 151 to the slave terminal 100 via the wireless LAN communication unit 220. Then, the CPU 140 of the slave terminal 100 reads the application update list 151 from the storage unit 150 in response to the received acquisition request, and the application update list 151 is transferred to the mobile router 200 by the wireless LAN communication W11 via the wireless LAN communication unit 120. Send to When receiving the application update list 151 by the wireless LAN communication unit 220, the CPU 240 stores the application update list 251 in the storage unit 250 (S103). Thereafter, the CPU 240 monitors uplink data from the slave terminal 100. Uplink data is a transmission packet from the handset terminal 100 toward the communication network 300. For example, the slave terminal 100 transmits an update request of the application 152 addressed to the application management server 400 by the application update application. At this time, the slave terminal 100 transmits an update request to the mobile router 200 from the wireless LAN communication unit 120 through the wireless LAN communication W11.

  Subsequently, the mobile router 200 receives uplink data from the slave terminal 100 (S104). Specifically, the CPU 240 detects uplink data received by the wireless LAN communication W <b> 11 in the wireless LAN communication unit 220. Then, the CPU 240 analyzes the received uplink data (S105). Subsequently, the CPU 240 determines whether or not the detected uplink data is data from an application update application (application update application) of the slave terminal 100 (S106). If it is not the data from the application update application, the CPU 240 converts the detected uplink data into data for LTE, and transmits it to the communication network 300 by the LTE communication W21 using the LTE wireless unit 210 (S107). In this case, since the uplink data is from applications other than the application update application in the slave terminal 100, the uplink data is relayed to the communication network 300 as usual.

  On the other hand, if the data is from the application update application in step S106, the CPU 240 determines whether the detected uplink data is an acquisition request for the application in the application update list 251 (S108). Here, when the detected uplink data is an acquisition request for an application in the application update list 251, it is an acquisition request for an application 152 already installed in the slave terminal 100, and therefore an update version acquisition request. That is, it can be said that the acquisition request is an update request for the application 152. Therefore, in step S108, when the acquisition request is for the application in the application update list 251, the CPU 240 blocks the uplink data. Then, the CPU 240 notifies the slave terminal 100 that the update of the application 152 has been interrupted (S109). Specifically, CPU 240 discards the uplink data, and transmits to wireless device terminal 100 that update of application 152 to be updated is stopped by wireless LAN communication W11 using wireless LAN communication unit 220.

  On the other hand, if the acquisition request is not for the application in the application update list 251 in step S108, it can be said that the acquisition request is for the new application 402 not installed in the slave terminal 100. Then, in this case, it can be said that the download request is not the automatic update by the application update application but, for example, the download request of the application 402 by the operation of the user of the slave terminal 100. Therefore, the CPU 240 converts the detected uplink data into data for LTE, and transmits the data to the communication network 300 through the LTE communication W21 using the LTE radio unit 210 (S110). Thereafter, the acquisition request arrives at the application management server 400 via the communication network 300. The application management server 400 identifies the application 402 according to the received acquisition request. Then, the application management server 400 returns the application 402 via the communication network 300.

  Then, the mobile router 200 receives the application 402 from the communication network 300 by the LTE communication W21 in the LTE wireless unit 210. Then, the CPU 240 of the mobile router 200 transmits the application 402 to the child device terminal 100 by the wireless LAN communication W11 using the wireless LAN communication unit 220. At this time, the CPU 240 converts the download data of the new application 402 into data for the wireless LAN, and transmits the data to the slave terminal 100 via the wireless LAN communication W11 using the wireless LAN communication unit 220 (S111). Thereafter, the process returns to step S102.

  As described above, according to the second embodiment, when the application management application of the child device terminal 100 autonomously requests the update of the installed application, the update request is blocked. On the other hand, in the case of the acquisition request of communication data or a new application by another application, the mobile router 200 relays to the communication network 300 as usual. Thus, for example, even if "automatically update only when connected to WiFi" is set as the initial setting of the update setting of the application management application, the automatic update is prevented at unexpected times of the user. Can. Therefore, the application can be automatically updated in a more stable communication environment. Further, even when the communication charge is added according to the communication data amount of LTE, the download of the large-capacity data can be prevented automatically, so that the communication charge can be suppressed.

Embodiment 3
The third embodiment is a modification of the second embodiment described above. That is, when the control unit according to the third embodiment receives the message from the radio information terminal, the first radio communication unit is also connected to the external network by the first radio access method. It is determined whether or not. When the control unit determines that the external network is also connected, the control unit transfers the received message to the communication device using the first wireless communication unit without discarding the received message. To do. As a result, when the WAN side of the communication relay device is communicating with a public WiFi or a WiFi device at home, the application can be automatically updated in a stable communication environment. Therefore, it is possible to prevent excessive suppression of automatic update of the application.

  FIG. 6 is a block diagram showing the configuration of a wireless communication system 2000a according to the third embodiment of the present invention. The wireless communication system 2000a is an improved example of the wireless communication system 2000 described above, and is obtained by replacing the mobile router 200 with the mobile router 200a. Since other configurations are the same as those of the wireless communication system 2000, detailed description thereof is omitted.

  The mobile router 200a differs from the mobile router 200 in that the wireless LAN communication unit 220 is connected to the communication network 300 by the wireless LAN communication W12. That is, it shows that the WAN side and the LAN side of the mobile router 200a are connected by wireless LAN communication. The mobile router 200a is obtained by replacing the CPU 240 in the mobile router 200 with the CPU 240a. When the CPU 240a receives a message from the slave terminal 100, the CPU 240a determines whether the wireless LAN communication unit 220 is also connected to the communication network 300 by the wireless LAN communication W12. When the CPU 240 a determines that the communication network 300 is also connected, the CPU 240 a uses the wireless LAN communication unit 220 to discard the received message to the application management server 400 via the communication network 300. Forward.

  FIG. 7 is a flowchart showing the flow of a control method of the communication relay apparatus according to the third embodiment of the present invention. FIG. 7 is one in which steps S201 and S202 are added between steps S104 and S105 in the flowchart of FIG. 5 described above. Therefore, below, a change with FIG. 5 is demonstrated.

  After step S104, the CPU 240a determines whether or not the WAN side is connected by the wireless LAN communication W12 (S201). When the WAN side is connected by the wireless LAN communication W12, the CPU 240a converts the detected uplink data into data for the wireless LAN, and transmits it to the communication network 300 by the wireless LAN communication W12 using the wireless LAN communication unit 220 ( S202).

  On the other hand, when the WAN side is not connected by the wireless LAN communication W12 in step S201, the CPU 240a executes the process of step S105 described above. Thereafter, the process continues to step S106.

Fourth Preferred Embodiment
The fourth embodiment is an improved example of the above-described second or third embodiment. That is, the communication relay device according to the fourth embodiment further includes a storage unit that stores a second list of wireless relay devices to which the wireless information terminal can be connected by the first wireless access method. In this case, when the wireless information terminal is connected to the first wireless communication unit, the control unit searches for a wireless relay device that can communicate with the first wireless access method. When the searched wireless relay device is included in the second list, the control unit disconnects the connection between the wireless information terminal and the first wireless communication unit. Thereby, even when the communication relay device and the wireless information terminal are connected by the first wireless access method, when there is another wireless relay device to which the wireless information terminal can be connected by the first wireless access method. And a wireless information terminal can be urged to connect with the wireless relay device. Therefore, the wireless information terminal can more stably realize automatic update of applications via the wireless relay device newly connected by the first wireless access method.

  Furthermore, it is preferable that the control unit stop the operation of the second wireless communication unit after disconnecting the connection between the wireless information terminal and the first wireless communication unit. Thereby, it is possible to prevent excessive battery consumption in the communication relay device.

  FIG. 8 is a block diagram showing the configuration of a wireless communication system 2000b according to the fourth embodiment of the present invention. The wireless communication system 2000b is an improved example of the above-described wireless communication system 2000, and the mobile router 200 is replaced with the mobile router 200b. Since other configurations are the same as those of the wireless communication system 2000, detailed description thereof is omitted. The mobile router 200b may be an improved version of the mobile router 200a.

  The mobile router 200 b is obtained by replacing the CPU 240 of the mobile router 200 with the CPU 240 b. In addition, the storage unit 250 stores an SSID (Service Set Identifier) list 252. The SSID is an identification name of an access point in the wireless LAN. The SSID list 252 is an example of a list of wireless relay devices to which the handset terminal 100 can be connected by the wireless LAN communication W11, that is, a wireless LAN base device. The wireless LAN parent device is, for example, a public WiFi or a home WiFi parent device. In the storage unit 250, the SSID list 252 is registered in advance. FIG. 9 is a diagram showing an example of the SSID list 252 according to the fourth embodiment of the present invention. Note that the storage unit 250 may store an application update list 251.

  Then, when the slave terminal 100 is connected to the wireless LAN communication unit 220, the CPU 240b searches for a wireless relay device that can communicate with the wireless LAN communication W11. When the searched wireless relay device is included in the SSID list 252, the CPU 240 b disconnects the connection between the child device terminal 100 and the wireless LAN communication unit 220. After that, the CPU 240b stops the operation of the LTE radio unit 210.

  FIG. 10 is a flowchart showing a flow of a control method of the communication relay device according to the fourth embodiment of the present invention. FIG. 10 is obtained by adding steps S301 to S305 between steps S101 and S102 in the flowchart of FIG. 5 described above. Therefore, below, a change with FIG. 5 is demonstrated.

  After step S101, the CPU 240b searches for a base unit of the wireless LAN (S301). Then, the CPU 240b compares the wireless LAN base unit included in the search result with the SSID list 252 stored in the storage unit 250 (S302). Then, the CPU 240b determines whether the search result is present in the SSID list 252 (S303). When the search result exists in the SSID list 252, the CPU 240 b disconnects the handset terminal 100 from belonging to the mobile router 200 b (S 304). As a result, the slave terminal 100 can connect to another wireless LAN access point included in the search result by the LTE communication W21 using the wireless LAN communication unit 120. Since the other wireless LAN access point is a public WiFi or WiFi master device at home, the slave terminal 100 can be directly connected to the WAN without going through the mobile router 200b. Therefore, the child device terminal 100 can perform the automatic update of the application stably by the LTE communication W21.

  Then, the CPU 240b transitions to the standby mode (S305). Specifically, the CPU 240b stops the operation of the LTE radio unit 210. Thereby, the power consumption of the LTE radio unit 210 can be suppressed. Thereafter, the process returns to step S101.

  On the other hand, when the search result is not present in the SSID list 252 in step S303, the process of step S102 described above is executed. Thereafter, the process continues to step S103.

  The fourth embodiment is not necessarily an improvement over the second or third embodiment. That is, it is not necessary to acquire the application update list from the slave terminal 100. Therefore, the fourth embodiment may have the following configuration. That is, the communication relay apparatus according to the fourth embodiment includes the first wireless communication unit, the second wireless communication unit, the control unit, and the storage unit. Here, the first wireless communication unit communicates with the wireless information terminal by the first wireless access method. The second wireless communication unit communicates with a communication device arranged on the external network by the second wireless access method. The control unit relays communication between the wireless information terminal and the communication apparatus using the first wireless communication unit and the second wireless communication unit. The storage unit stores a list of wireless relay apparatuses to which the wireless information terminal can be connected by the first wireless access method. At this time, when the wireless information terminal is connected to the first wireless communication unit, the control unit searches for a wireless relay device that can communicate with the first wireless access method. Then, when the searched wireless relay device is included in the list, the control unit disconnects the connection between the wireless information terminal and the first wireless communication unit. Even in such a configuration, the communication relay apparatus prevents the application update request from the wireless information terminal connected by the first wireless access method from being transferred to the external network by the second wireless access method. be able to. Therefore, the same effects as those of the first embodiment described above are obtained. Furthermore, it is not necessary to acquire an application update list from the wireless information terminal, and security risks can be reduced.

The Fifth Preferred Embodiment
The fifth embodiment is an improved example of the above-described second, third, or fourth embodiment. That is, the communication relay device according to the fifth embodiment further includes a sensor that detects the movement of the communication relay device. Then, after the wireless information terminal is connected to the first wireless communication unit, the control unit determines whether the communication relay device is moving using the sensor. When the control unit determines that the communication relay device is moving, the control unit determines whether the message received from the wireless information terminal is an application update request in the wireless information terminal. . As described above, since the communication stability is low when the communication relay device is moving, as described above, the update failure can be suppressed by avoiding the application update request.

  FIG. 11 is a block diagram showing the configuration of a wireless communication system 2000 c according to the fifth embodiment of the present invention. The wireless communication system 2000c is an improvement of the above-described wireless communication system 2000b, in which the mobile router 200b is replaced with the mobile router 200c. Since the other configuration is the same as that of the wireless communication system 2000b, detailed description is omitted. The mobile router 200c may be an improvement of the mobile router 200 or 200a.

  In the mobile router 200c, the CPU 240b in the mobile router 200b is replaced with the CPU 240c, and a sensor 260 is newly added. The sensor 260 has a function of detecting movement of the mobile router 200c. Then, when the movement of the mobile router 200c is detected, the sensor 260 outputs a detection signal indicating the detection to the CPU 240c. For example, the sensor 260 is a GPS (Global Positioning System), an acceleration sensor, or the like. In addition, after the slave terminal 100 is connected to the wireless LAN communication unit 220, the CPU 240c uses the sensor 260 to determine whether the mobile router 200c is moving. If the CPU 240c determines that the mobile router 200c is moving, the CPU 240c determines whether the message received from the child device terminal 100 is an application update request in the child device terminal 100.

  FIG. 12 is a flowchart showing a flow of a control method of the communication relay device according to the fifth embodiment of the present invention. In FIG. 12, steps S401 and S402 are added between steps S101 and S301 in the flowchart of FIG. 10 described above, and the positions of steps S102 and S103 are changed. Therefore, below, a change with FIG. 10 is demonstrated.

  After step S101, the CPU 240c determines whether the mobile router 200c is moving (S401). Specifically, the CPU 240c determines the movement of the mobile router 200c based on the detection signal from the sensor 260. If it is determined in step S401 that the mobile router 200c has not moved, the process of S301 described above is executed.

  On the other hand, when it is determined in step S401 that the mobile router 200c is moving, the CPU 240c determines whether or not the application update list 251 has been acquired from the slave terminal 100 (S402). If the application update list 251 has not been acquired, the CPU 240 c requests the child terminal 100 to apply the application update list 151 (S 102). When the wireless LAN communication unit 220 receives the application update list 151, the CPU 240c stores the application update list 151 in the storage unit 250 (S103).

  If it is determined in step S402 that the application update list 251 has not been acquired, or after step S103, the above-described step S104 is executed.

  Note that the communication relay device control method according to the fifth embodiment may be modified as follows. FIG. 13 is a flowchart showing a flow of a control method of the communication relay apparatus according to another example of the fifth embodiment of the present invention. In FIG. 13, the processing after step S402 in the flowchart of FIG. 12 is changed from step S403 to S406. Therefore, below, a change with FIG. 12 is demonstrated.

  When it is determined in step S401 that the mobile router 200c is moving, the CPU 240c monitors uplink data from the slave terminal 100 (S403). Then, it is assumed that the mobile router 200c receives uplink data from the slave terminal 100. At this time, the CPU 240 c determines whether the detected uplink data is data from the application update application of the slave terminal 100 (S 406). If it is not data from the application update application, the CPU 240 c converts the detected uplink data into data for LTE, and transmits the data to the communication network 300 by the LTE communication W 21 using the LTE wireless unit 210 (S 405).

  On the other hand, if the data is from the application update application in step S404, the CPU 240c blocks the detected uplink data, and notifies the slave terminal 100 that the application update has been interrupted (S406). In this case, since the mobile router 200c is moving, it is desirable to avoid downloading the application, not only updating or newly, if it is uplink data from the application updating application. Note that instead of step S406, as in step S108 described above, only updating of the application may be suppressed.
