  In the standard based on IEEE802.11 wireless LAN communication such as Wi-Fi communication, an infrastructure mode (Infrastructure Mode) is defined as one of operation modes for connecting a Wi-Fi line. In the infrastructure mode, one of the connected terminals operates as an access point and the other operates as a station, so that a wireless LAN line can be connected and wireless LAN communication is established. Moreover, in the standard based on Wi-Fi communication, in addition to the infrastructure mode, a direct mode (Wi-Fi direct) is defined. In the direct mode, both connected terminals operate equally as P2P (Peer to Peer) devices, so that a Wi-Fi line can be connected and Wi-Fi communication is established.

  Next, the operation of the above-described configuration will be described with reference to FIGS. Here, it is assumed that the Wi-Fi communication unit 33 of the Wi-Fi router 3 operates as an access point in the infrastructure mode (A1), and the user uses the wireless LAN communication terminal 2 at home and then in the vehicle A process performed by each of the wireless LAN communication terminal 2, the Wi-Fi router 3, and the in-vehicle device 4 in a situation where the wireless LAN communication terminal 2 is brought in and used will be described.

  In the wireless LAN communication terminal 2, the control unit 21 performs Wi-Fi communication with the Wi-Fi router 3 if the wireless LAN communication terminal 2 and the Wi-Fi router 3 exist in the Wi-Fi communication area. Perform mutual authentication. When determining that mutual authentication of Wi-Fi communication is established with the Wi-Fi router 3, the control unit 21 determines the operation state of the Wi-Fi communication unit 33 of the Wi-Fi router 3. When the control unit 21 determines that the Wi-Fi communication unit 33 of the Wi-Fi router 3 is operating as an access point in the infrastructure mode, the control unit 21 operates the Wi-Fi communication unit 23 as a station in the infrastructure mode. (B1), a Wi-Fi line is connected in the infrastructure mode between the Wi-Fi communication unit 23 and the Wi-Fi communication unit 33. As a result, the control unit 21 establishes Wi-Fi communication with the Wi-Fi router 3 (A2, B2).

When it is determined that the Bluetooth connection request transmitted from the unit 43 is received by the Bluetooth communication unit 24, mutual authentication of Bluetooth communication with the in-vehicle device 4 is performed. When the control unit 21 determines that the mutual authentication of the Bluetooth communication is established with the in-vehicle device 4, the control unit 21 connects the Bluetooth line between the Bluetooth communication unit 24 and the Bluetooth communication unit 43. Thereby, the control part 21 establishes Bluetooth communication between the vehicle equipment 4 (B3, C2).

The control unit 21 causes the Wi-Fi communication unit 23 to transmit a Wi-Fi disconnection request after establishing Bluetooth communication with the in-vehicle device 4. In this case, the control unit 21 causes the Wi-Fi communication unit 23 to transmit a Wi-Fi disconnection request even if the wireless LAN communication terminal 2 is not out of the Wi-Fi communication area of the Wi-Fi router 3. The Wi-Fi line connected between the Wi-Fi communication unit 23 and the Wi-Fi communication unit 33 is disconnected.

Obtain and judge. If the Wi-Fi communication unit 42 of the in-vehicle device 4 that is a new Wi-Fi connection destination is operating as a station in the infrastructure mode (C1), the control unit 21 is the Wi-Fi communication unit 23. While the operation mode is set to the infrastructure mode, the function of the infrastructure mode is switched from the station to the access point (B4), and the Wi-Fi communication unit 23 is operated as the access point of the infrastructure mode (B5).

  Next, the control unit 21 causes “Probe Request” to be transmitted from the Wi-Fi communication unit 23 to the Wi-Fi communication unit 42 of the in-vehicle device 4. When the control unit 21 receives “Probe Response” transmitted from the Wi-Fi communication unit 42 of the in-vehicle device 4 from the Wi-Fi communication unit 42 of the in-vehicle device 4 by the Wi-Fi communication unit 23, the control unit 21 communicates with the in-vehicle device 4. Mutual authentication of Wi-Fi communication is performed between them. And if the control part 21 determines with the mutual authentication of Wi-Fi communication having been materialized with the vehicle equipment 4, it will establish a Wi-Fi line between the Wi-Fi communication part 23 and the Wi-Fi communication part 42. Connect in infrastructure mode. Thereby, the control unit 21 establishes Wi-Fi communication with the in-vehicle device 4 (B6, C3) (executes the second procedure).

  As described above, as shown in FIG. 3, when the user brings the wireless LAN communication terminal 2 into the vehicle in a state where the Wi-Fi communication unit 42 of the in-vehicle device 4 is operating as an infrastructure mode station. In response to the establishment of Bluetooth communication by the user switching the ACC switch 6 from off to on, the wireless LAN communication terminal 2 keeps the operation mode of the Wi-Fi communication unit 23 in the infrastructure mode, and the infrastructure Switch the structure mode function from station to access point. This enables seamless (automatic) from Wi-Fi communication in the home to Wi-Fi communication in the vehicle without the user performing an operation to switch the function or operation mode of the infrastructure mode (not manually). ) Can be switched.

(2) Processing for Switching Operation Mode In this case as well, when the control unit 21 establishes Bluetooth communication between the wireless LAN communication terminal 2 and the in-vehicle device 4, the control unit 21 performs communication between the wireless LAN communication terminal 2 and the in-vehicle device 4. It determines with the connection request | requirement of Wi-Fi communication having generate | occur | produced (1st procedure is performed), and acquires the operation state of the Wi-Fi communication part 42 of the vehicle equipment 4 by Bluetooth communication, and determines. If the Wi-Fi communication unit 42 of the in-vehicle device 4 that is a new Wi-Fi connection destination is operating as a P2P device in the direct mode (C11), the control unit 21 is the Wi-Fi communication unit 23. The operation mode is switched from the infrastructure mode to the direct mode (B11), and the Wi-Fi communication unit 23 is operated as a P2P device in the direct mode (B12).

  Next, the control unit 21 transmits / receives “Find” between the Wi-Fi communication unit 23 and the Wi-Fi communication unit 42 of the in-vehicle device 4, and performs mutual authentication of Wi-Fi communication with the in-vehicle device 4. Do. And if the control part 21 determines with the mutual authentication of Wi-Fi communication having been materialized with the vehicle equipment 4, it will establish a Wi-Fi line between the Wi-Fi communication part 23 and the Wi-Fi communication part 42. Connect in direct mode. Thereby, the control unit 21 establishes Wi-Fi communication with the in-vehicle device 4 (B13, C12) (executes the second procedure).

  As described above, as shown in FIG. 5, when the user brings the wireless LAN communication terminal 2 into the vehicle while the Wi-Fi communication unit 42 of the in-vehicle device 4 is operating as a direct mode P2P device. The wireless LAN communication terminal 2 switches the operation mode of the Wi-Fi communication unit 23 from the infrastructure mode to the direct mode when the Bluetooth communication is established by the user switching the ACC switch 6 from OFF to ON. Thus, in this case, the user can seamlessly change from Wi-Fi communication in the home to Wi-Fi communication in the vehicle without performing an operation of switching the function or operation mode of the infrastructure mode (not manually). Can be switched to (automatically).

  In the above, Wi-Fi communication has been described as an example. However, if the system can connect wireless LAN lines between connected terminals in infrastructure mode, the above-mentioned “(1) Infrastructure mode function” The “switching process” can be applied to other wireless LAN communications.

  As described above, according to this embodiment, when the wireless LAN communication terminal 2 switches the connection destination of Wi-Fi communication from the Wi-Fi router 3 to the vehicle-mounted device 4, the functions and operations of the infrastructure mode are performed. The mode was changed automatically. This eliminates the need for the user to switch the infrastructure mode function and operation mode, and can seamlessly switch from Wi-Fi communication in the home to Wi-Fi communication in the vehicle, improving convenience. it can.

Automatically switched from to the access point. This eliminates the need for the user to switch the infrastructure mode function from the station to the access point. In the situation where the Wi-Fi communication unit 42 of the in-vehicle device 4 is operating as a P2P device in the direct mode, the operation mode is automatically switched from the infrastructure mode to the direct mode. This eliminates the need for the user to switch the operation mode from the infrastructure mode to the direct mode.

  Further, in the wireless LAN communication terminal 2, when the connection destination is switched from the Wi-Fi router 3 to the in-vehicle device 4, a Wi-Fi disconnect request is transmitted. Thereby, by transmitting the Wi-Fi disconnection request, the Wi-Fi line connected to the Wi-Fi router 3 can be surely disconnected, and the Wi-Fi line is connected to the Wi-Fi router 3. It is possible to avoid problems that are assumed due to the fact that they are still connected (not disconnected).

  In the wireless LAN communication terminal 2, the connection destination is set to the Wi-Fi router 3 when the user gets on the vehicle, switches the ACC switch 6 from OFF to ON, and connects the Bluetooth line with the in-vehicle device 4. Was switched from in-vehicle device 4 to in-vehicle device 4. As a result, the Wi-Fi line can be connected in the vehicle immediately after the user gets on the vehicle and the ACC switch 6 is switched from OFF to ON, and an application using Wi-Fi communication in the vehicle is provided to the user. can do.

May be configured to switch from the Wi-Fi router 3 to the in-vehicle device 4.

  When the Bluetooth communication is established with the in-vehicle device 4 in the wireless communication terminal 2 (when the Bluetooth line connection is normally completed), it is determined that a connection request for Wi-Fi communication has occurred with the in-vehicle device 4. However, the present invention may be configured to determine the setting of automatic connection of Wi-Fi communication after establishing Bluetooth communication. That is, if the user can set the automatic connection on / off of Wi-Fi communication in advance and establish the Bluetooth communication and the automatic connection setting of Wi-Fi communication is on, a connection request for Wi-Fi communication is made. It may be configured to determine that it has occurred. In addition, if the automatic connection setting of Wi-Fi communication is off after establishing Bluetooth communication, the Wi-Fi communication automatic connection setting is switched on from the OFF state to the ON state. It may be configured to determine that a connection request for Fi communication has occurred. Since the user can set ON / OFF of automatic connection of Wi-Fi communication in advance, whether or not to automatically connect the Wi-Fi line in the vehicle can be selected in advance, and convenience can be improved.
