  The mounting method of the functional units denoted by reference numerals 11 to 22 shown in FIG. 1 is arbitrary. In general, an access point search function, a mobile data communication function, and a WiFi connection function are provided by the OS (Operating System) of the smart terminal 100. Therefore, in the present embodiment, each function unit provided there is an access point on the OS. The detection unit 14, the mobile data communication unit 19, and the WiFi connection unit 15 are used. Since the WiFi setting information and the access point information are also stored in the storage means on the OS, the WiFi setting information storage unit 12 and the access point information storage unit 16 on the OS are used. Then, a WiFi connection terminal for connecting all the remaining functional units to WiFi, that is, an application program operating on the OS is used. Of course, all the functional units of reference numerals 11 to 22 may be realized by the application program. Hereinafter, the function of each functional unit will be described.

  The WiFi setting control unit 11 is configured to automatically change ON / OFF of the WiFi setting information stored in the WiFi setting information storage unit 12 at a predetermined timing. Specifically, even when the WiFi setting is OFF, it is automatically changed to ON periodically. Also, after changing the WiFi setting to ON, if there is no connectable access point AP, or if the WiFi connection cannot be established with the connectable access point AP, the WiFi setting is automatically returned to OFF.

  The WiFi setting information storage unit 12 is configured to store WiFi setting information in which whether or not to perform a WiFi connection is defined. Set by the user of the smart terminal 100, for example, ON is set when WiFi connection is performed, and OFF is set when WiFi connection is not performed.

  The access point detection connection command unit 13 refers to the WiFi setting information in the WiFi setting information storage unit 12, instructs the access point detection unit 14 to detect the access point AP after the WiFi setting is changed to ON, and is detected. It is configured to instruct the WiFi connection unit 15 to perform WiFi connection processing to the access point AP.

  The access point detection unit 14 is configured to search for nearby access point APs based on the access point detection command from the access point detection connection command unit 13 and detect access points AP within the radio wave reachable range.

  The WiFi connection unit 15 performs WiFi connection to the access point AP detected by the access point detection unit 14 based on the WiFi connection command from the access point detection connection command unit 13, and connected access point information related to the WiFi-connected access point AP Is stored in the access point information storage unit 16.

  The access point information storage unit 16 is configured to store information related to the access point AP that is WiFi-connected by the WiFi connection unit 15 as connected access point information.

  The WiFi connection state detection unit 17 is configured to refer to the connection result of the WiFi connection to the access point AP performed by the WiFi connection unit 15 and detect whether or not the smart terminal 100 is in the WiFi connection. Yes.

  The mobile data communication control unit 18 is configured to control mobile communication to the mobile communication network N by the mobile data communication unit 19. Specifically, the WiFi connection status of the smart terminal 100 performed by the WiFi connection status detection unit 17 is referred to. When the WiFi connection is established, the mobile data communication setting is automatically changed to OFF, and the WiFi connection is disconnected. Return to ON automatically.

  The mobile data communication unit 19 is an interface for data communication with a mobile communication network N such as a mobile carrier among a plurality of communication interfaces provided in the smart terminal 100. The mobile data communication setting information is held, and when ON, data communication is started with the mobile communication network N to transmit packet data, and when OFF, no data communication operation is performed.

  When the access point AP is detected by the access point detection unit 14, the WiFi connectability notification unit 20 acquires the detection result from the access point detection connection command unit 13, and notifies the smart terminal 100 that the WiFi connection is possible. It is configured to notify the user U via the screen.

  The WiFi connection command unit 21 instructs the WiFi connection unit 15 to perform the WiFi connection process only when the WiFi connection is instructed by the user U based on the WiFi connection possible notification from the WiFi connection notification unit 20 so that the WiFi connection unit 15 performs the WiFi connection. It is configured.

  The access point information management unit 22 controls the connected access point information stored in the access point information storage unit 16 based on the connection result of the WiFi connection to the access point AP performed by the WiFi connection state detection unit 17. It is configured as follows. Specifically, when the disconnection of the WiFi connection is detected, the connected access point information related to the access point AP connected so far is deleted.

  Next, a WiFi connection method performed by the smart terminal 100 will be described. First, a WiFi connection method for performing WiFi connection with power saving will be described. Basically, the WiFi setting is turned off, and the WiFi setting is turned on periodically to search for nearby access points AP as needed. When a connectable access point AP is found, a WiFi connection is automatically made. Furthermore, the mobile data communication setting is set to OFF only during WiFi connection. Hereinafter, this will be specifically described with reference to FIG. FIG. 2 is a diagram showing a first WiFi connection processing flow. However, the description will proceed on the assumption that the WiFi setting is OFF and the mobile data communication setting is ON.

  First, in step S101, the WiFi setting control unit 11 refers to the WiFi setting information in the WiFi setting information storage unit 12, and automatically changes the WiFi setting that is OFF to ON. At this time, since the mobile data communication setting is ON, the smart terminal 100 can communicate with the Internet via the mobile communication network N at this time.

  Next, in step S102, the access point detection connection command unit 13 instructs the access point detection unit 14 to perform access point AP detection processing because the WiFi setting is set to ON in step S101. Searches for nearby access point APs and detects connectable access point APs.

  Next, in step S103, the access point detection connection command unit 13 determines whether an access point AP to which the smart terminal 100 can be connected is detected based on the detection result in step S102. If a connectable access point is not detected, the process proceeds to step S104. If detected, the process proceeds to step S105.

  In step S104, since no connectable access point has been detected, the access point detection / connection command unit 13 notifies the WiFi setting control unit 11 to that effect, and the WiFi setting control unit 11 changes to ON in step S101. Return the WiFi setting that was set to OFF. Then, it returns to step S101 and the process from the said step S101 is repeated regularly after a fixed time.

  On the other hand, in step S105, since the connectable access point is detected in step S103, the access point detection / connection command unit 13 instructs the WiFi connection unit 15 to perform WiFi connection processing to the detected access point AP, and WiFi. The connection unit 15 attempts a WiFi connection to the access point AP using a BSSID (Basic Service Set Identifier), a password, or the like that is held.

  Next, in step S106, the access point detection connection command unit 13 determines whether or not the smart terminal 100 has been able to connect to the WiFi based on the WiFi connection result in step S105. If the WiFi connection cannot be established, the process proceeds to step S104 as in the case where the access point is not detected, and the WiFi setting control unit 11 returns the WiFi setting information changed to ON in step S101 to OFF. On the other hand, if the WiFi connection is established, the process proceeds to step S107.

  In step S107, since the WiFi connection to the access point AP has been performed, the mobile data communication control unit 18 moves the mobile data communication unit 19 by changing the mobile data communication setting that has been turned on until now. The mobile data communication with the body communication network N is disconnected. At this point, the smart terminal 100 can connect to the Internet via the WiFi-connected access point AP instead of the mobile communication network N.

  Next, in step S108, the WiFi connection state detection unit 17 detects the current WiFi connection state of the smart terminal 100, and when the WiFi connection is disconnected, the WiFi setting control unit 11 changes to ON in step S101. The WiFi setting that has been changed is returned to OFF, and the mobile data communication control unit 18 returns the mobile data communication setting that has been changed to OFF in step S107 to ON. Then, it returns to step S101 and the process from the said step S101 is repeated regularly after a fixed time.

  In addition, each process of step S101 and step S104 is fluctuate | varied by the WiFi setting at the time of the start of the said regular operation | movement. FIG. 3 is a diagram illustrating the processing contents of step S101 and step S104 according to the preset value of WiFi setting by the user U. When the preset value of the WiFi setting is ON instead of OFF, since it is already ON, the “automatically change the WiFi setting that is OFF to ON” processing performed in step S101, “ The “return WiFi setting changed to ON” is not performed. That is, the smart terminal 100 confirms the preset value of the WiFi setting preset by the user U before the regular operation, and determines the processing contents of step S101 and step S104 according to the value. As described above, the WiFi setting performed by the user U may be applied with priority, and the processing of the periodic operation may be determined and executed based on the setting.

  Next, an example of processing operation when the smart terminal 100 moves will be described with reference to FIG. The following processing operation examples are executed based on the series of operations described above. First, as shown in the timing of T1, when there is no access point AP to be connected around the smart terminal 100, the smart terminal 100 turns off the WiFi setting and turns on the mobile data communication setting.

  After that, the smart terminal 100 periodically changes the WiFi setting to ON and repeatedly tries to search for the access point AP and connect to the WiFi. However, as shown in the timing of T2, when the access point AP that attempted the WiFi connection is not connected, even if the access point AP is detected, the WiFi setting is turned OFF and the mobile data communication setting is turned ON. Keep it.

  On the other hand, as shown in the timing of T3, when the access point AP that attempted the WiFi connection is a connection target, the WiFi connection is performed based on the WiFi setting that has been changed to ON. As a result, the smart terminal 100 prioritizes data communication via the access point AP and temporarily changes the mobile data communication setting to OFF.

  Finally, as shown in the timing of T4, when detecting the disconnection of the WiFi connection, the smart terminal 100 returns the WiFi setting that has been changed to ON to OFF, and the mobile data communication setting that has been changed to OFF is turned ON. return.

  As described above, even when the WiFi setting of the smart terminal 100 is turned OFF, the first WiFi connection method is automatically turned ON periodically to search the WiFi radio wave condition and there is no access point AP to be connected. , The WiFi setting is automatically turned off. Also, when the WiFi connection is established, the mobile data communication setting is automatically turned OFF once, and the mobile data communication setting is automatically turned ON when the WiFi is disconnected.

  Conventionally, when the WiFi connection is automatically performed, it is necessary to always turn on the WiFi setting of the smart terminal 100. On the other hand, according to the first WiFi connection method, the WiFi setting is turned ON only when the WiFi connection is possible, and the mobile data communication setting is turned OFF during the WiFi connection, so that the battery consumption of the smart terminal 100 is reduced. Can do.

  Conventionally, access point detection and WiFi connection have been actively performed when radio waves from the access point AP are detected. In other words, from the viewpoint of an application program that wants to use the access point detection result, it is necessary to wait for service processing to be provided until the OS finds the access point AP and performs WiFi connection. On the other hand, according to the first WiFi connection method, the access point detection connection command unit 13 of the WiFi connection terminal (application program) performs the access point detection process or the WiFi connection process on the access point detection unit 14 or the WiFi connection unit on the OS. 15 is actively instructed, so the waiting time until the WiFi connection to the access point AP can be shortened.

  Furthermore, in the first WiFi connection method, the WiFi setting and the mobile data communication setting are performed automatically and autonomously, so that it is possible to reduce the trouble of the user U changing the setting.

  Next, the second WiFi connection method will be described. Second, in addition to the automatic WiFi connection method for automatic WiFi connection as described above, a notification WiFi connection method for making a WiFi connection based on an instruction from the user will be described.

  Conventionally, when the smart terminal 100 is activated, the smart terminal 100 automatically establishes a WiFi connection within the WiFi communication area. As a result, for example, in a public wireless LAN service in which the number of WiFi connections per day is restricted, there is a possibility that the number of connection restrictions has been reached without the user himself / herself being aware.

  Therefore, the second WiFi connection method is intended to meet the user's desire to know that he is in the WiFi communication area, although automatic connection is not desired. Specifically, the smart terminal 100 searches for nearby access point APs, and notifies the user when a connectable access point AP is found. Details will be described below.

  First, before describing the notification WiFi connection method, the automatic WiFi connection method will be described. FIG. 5 is a diagram showing a second WiFi connection processing flow (automatic WiFi connection processing flow). FIG. 6 is a diagram illustrating an example of an automatic WiFi connection processing operation when the smart terminal 100 moves.

  First, in step S201, the access point detection connection command unit 13 refers to the WiFi setting information in the WiFi setting information storage unit 12, and if it is ON, instructs the access point detection unit 14 to detect the access point AP. The access point detection unit 14 searches for nearby access point APs and detects connectable access point APs.

  Thereafter, in step S202, when an access point AP that can be connected is detected in step S201, the access point detection / connection instruction unit 13 instructs the WiFi connection unit 15 to perform WiFi connection processing to the detected access point AP, The WiFi connection unit 15 automatically establishes a WiFi connection to the access point AP using the BSSID, password, and the like that are held.

  Next, the notification WiFi connection method will be described. FIG. 7 is a diagram showing a second WiFi connection processing flow (notification WiFi connection processing flow). FIG. 8 is a diagram illustrating a notification WiFi connection processing operation example when the smart terminal 100 moves.

  First, in step S301, the access point detection connection command unit 13 refers to the WiFi setting information in the WiFi setting information storage unit 12, and if it is ON, instructs the access point detection unit 14 to detect the access point AP, The access point detection unit 14 searches for nearby access point APs and detects connectable access point APs.

  Next, in step S302, when an access point AP that can be connected is detected in step S301, the access point detection / connection instruction unit 13 transmits the detection result to the WiFi connectability notifying unit 20, and the WiFi connectable notifying unit 20 is detected. Displays on the screen of the smart terminal 100 that the WiFi connection is possible and notifies the user U.

  Thereafter, in step S303, the WiFi connection command unit 21 performs the WiFi connection processing to the access point AP detected in step S301 only when the WiFi connection notification screen displayed on the screen is tapped. The WiFi connection unit 15 makes a WiFi connection to the access point AP using the BSSID, password, and the like that are held.

  As described above, according to the second WiFi connection method, the peripheral access point AP is automatically searched, and if there is a connection target access point AP, the user U is notified that the WiFi connection is possible. Since the user U performs the WiFi connection only when instructing the WiFi connection, the user U can grasp that the user has entered the WiFi communication area, and the user U is aware of the public wireless LAN service connection frequency regulation without being aware of it. Can be prevented.

  Next, the third WiFi connection method will be described. Third, a WiFi connection method for avoiding WiFi connection to an access point AP that is not intended by the user U will be described.

  Conventionally, once a user U connects to an access point AP that requires WEB authentication, such as an access point installed at a play spot, once connected to the OS (access point information storage unit 16) of the smart terminal 100, the connection is completed. Access point information is retained. As a result, the OS may make a WiFi connection to the access point AP at a timing unintended by the user U. At that time, since the WiFi connection is performed using the stored connected access point information, the WEB authentication is not performed again, and thus there is a possibility that the connection to the Internet may be impossible without the user U's awareness. is there.

  Therefore, the third WiFi connection method is intended to prevent the WiFi connection to the access point AP that is not intended by the user U, and to prevent the state in which the WiFi connection is not possible before the user U notices. . Specifically, the connected access point information in the OS is deleted at the timing when the WiFi connection is disconnected. Hereinafter, a description will be given with reference to FIG. FIG. 9 is a diagram showing a third WiFi connection processing flow.

  First, in step S401, the WiFi connection state detection unit 17 detects that the WiFi connection to the access point AP by the smart terminal 100 has been disconnected.

  Thereafter, in step S402, when the smart terminal 100 is in WiFi connection, the access point information management unit 22 accesses the access point information storage unit 16 because the WiFi connection has been disconnected. When the smart terminal 100 is disconnected, the WiFi connection unit 15 Delete the stored connected access point information. That is, the connected access point information held by the OS is deleted when the WiFi connection is disconnected.

  Next, a third processing operation example when the smart terminal 100 moves will be described with reference to FIG. The following processing operation examples are executed based on the series of operations described above. First, as shown in the timing of T1, when there is no connectable access point AP around the smart terminal 100, the connected access point information is not registered in the access point information storage unit 16 in the OS.

  Thereafter, as shown in the timing of T2, when entering the WiFi communication area, the smart terminal 100 registers the access point information related to the access point AP in the area with the OS, and automatically connects to the access point AP with WiFi. After that, WEB authentication is performed to enable connection to the Internet.

  Then, as shown in the timing of T3, when leaving the WiFi communication area, the smart terminal 100 disconnects the WiFi connection and deletes the connected access point information registered in the OS. Since there is no connected access point information, it is possible to prevent the OS from making a WiFi connection to the access point AP at a timing unintended by the user U.

  After that, as shown in the timing of T4, when entering the WiFi communication area again, the smart terminal 100 newly registers the access point information related to the access point AP in the area in the OS, and the WiFi is transferred to the access point AP. Connect and perform WEB authentication. Since the WiFi connection and WEB authentication are performed again, it is possible to prevent the state where the WiFi connection is impossible.

  As described above, according to the third WiFi connection method, since the connected access point information in the OS is deleted, the WiFi connection to the access point AP that is not intended by the user U is prevented, and the user U can be smart without being aware of it. It is possible to prevent the terminal 100 from being disabled for WiFi connection.

  As described above, according to the present embodiment, the WiFi setting is periodically changed to ON, returned to OFF when there is no access point AP to be connected, and connected when the WiFi connection is established with the access point AP to be connected. Since the communication setting of the mobile communication network N that has been changed is changed to OFF, the power consumption of the smart terminal 100 can be suppressed. In addition, after the WiFi setting is changed to ON, the access point detection unit 14 is instructed to detect the access point AP, and the WiFi connection unit 15 is instructed to perform the WiFi connection to the detected access point AP. The waiting time until the WiFi connection to the access point AP can be shortened.

  Further, according to the present embodiment, the user U is notified that the access point AP has been detected before the WiFi connection to the detected access point AP, so that the user U has entered the WiFi communication area. It can be grasped, and it can be prevented that the user U falls under the WiFi connection frequency regulation without noticing.

  Further, according to the present embodiment, the connected access point information by the WiFi connection to the access point AP to be connected is deleted after the WiFi connection is disconnected, so that the WiFi connection to the access point AP that is not intended by the user U is prevented. In addition, it is possible to prevent the smart terminal 100 from being disabled for WiFi connection without the user U's awareness.

  Finally, the smart terminal 100 described in this embodiment can be realized by a computer having a memory and a CPU. For example, it can be realized using a general-purpose information processing terminal having a WiFi connection function, a GPS function, a communication function, and the like, such as a smartphone, a tablet, and a mobile phone. The process is executed by a program. Furthermore, each operation of the smart terminal 100 can be constructed as a program, installed in a computer and executed, or distributed via a communication network.
