例えばＷｉ−Ｆｉ（Wireless Fidelity、登録商標）通信等の無線ＬＡＮ通信では、動作モードの１つとしてインフラストラクチャモードが規定されている。インフラストラクチャモードでは、接続端末同士の一方がアクセスポイントとして動作すると共に他方がステーションとして動作することで、無線ＬＡＮ回線を接続可能となる。   For example, in wireless LAN communication such as Wi-Fi (Wireless Fidelity, registered trademark) communication, an infrastructure mode is defined as one of operation modes. 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.

上記した無線ＬＡＮ通信端末が接続先の接続相手端末を切換える状況として、例えば無線ＬＡＮ通信端末が宅内で使用される状況では宅内に設置された無線ＬＡＮルータとの間で無線ＬＡＮ回線を接続し、無線ＬＡＮ通信端末が車内に持ち込まれて使用される状況では車載機との間で無線ＬＡＮ回線を接続する場合がある。このような場合、例えば宅内に設置された無線ＬＡＮルータがアクセスポイントとして動作していると、無線ＬＡＮ通信端末はステーションとして動作する。その後、無線ＬＡＮ通信端末がステーションとして動作しているまま車内に持ち込まれると、車載機がステーションとして動作している状況では、無線ＬＡＮ通信端末及び車載機の双方がステーションとして動作していることになり、両者の間で無線ＬＡＮ回線を接続不可能である。そのため、無線ＬＡＮ通信端末の動作をステーションからアクセスポイントに切換えるための操作をユーザが行う必要がある。このように従来では、無線ＬＡＮ通信端末が接続先の接続相手端末を切換える際に、ユーザが無線ＬＡＮ通信端末の動作を切換える操作を行う必要があり、利便性の点で改善する余地がある。   As a situation where the wireless LAN communication terminal switches the connection partner terminal of the connection destination, for example, in a situation where the wireless LAN communication terminal is used in a home, a wireless LAN line is connected to a wireless LAN router installed in the home, In a situation where the wireless LAN communication terminal is brought into the vehicle and used, a wireless LAN line may be connected to the in-vehicle device. In such a case, for example, when a wireless LAN router installed in a home is operating as an access point, the wireless LAN communication terminal operates as a station. After that, when the wireless LAN communication terminal is brought into the vehicle while operating as a station, both the wireless LAN communication terminal and the in-vehicle device are operating as stations in a situation where the in-vehicle device is operating as a station. Therefore, a wireless LAN line cannot be connected between the two. Therefore, the user needs to perform an operation for switching the operation of the wireless LAN communication terminal from the station to the access point. As described above, conventionally, when the wireless LAN communication terminal switches the connection destination terminal, the user needs to perform an operation of switching the operation of the wireless LAN communication terminal, and there is room for improvement in terms of convenience.

本発明は、上記した事情に鑑みてなされたものであり、その目的は、接続先の接続相手端末を切換える際に、ユーザによる操作を不要とすることで、利便性を高めることができる無線ＬＡＮ通信端末、車両無線ＬＡＮ通信システム及び無線ＬＡＮ回線接続制御プログラムを提供することにある。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to make it possible to improve convenience by eliminating the need for user operation when switching a connection partner terminal. The object is to provide a communication terminal, a vehicle wireless LAN communication system, and a wireless LAN line connection control program.

請求項１に記載した発明によれば、無線ＬＡＮ通信手段は、第１の接続相手端末及び第２の接続相手端末との間でそれぞれ無線ＬＡＮ回線を択一的に接続可能である。制御手段は、無線ＬＡＮ通信手段における無線ＬＡＮ回線の接続及び切断を制御する。ここで、制御手段は、インフラストラクチャモードのアクセスポイントとして動作する第１の接続相手端末を無線ＬＡＮ回線の接続先としたことで、無線ＬＡＮ通信手段をインフラストラクチャモードのステーションとして動作させている状態で、第２の接続相手端末と無線ＬＡＮ通信手段との間での無線ＬＡＮ回線の接続要求が発生したことを検知すると、第１の接続相手端末と無線ＬＡＮ通信手段との間で無線ＬＡＮ回線が切断されていることを条件として、第２の接続相手端末と無線ＬＡＮ通信手段との間で無線ＬＡＮ回線を自動で接続させる。これにより、接続先の接続相手端末を第１の接続相手端末から第２の接続相手端末に切換える際に、無線ＬＡＮ通信端末の動作を切換えるためのユーザによる操作を不要とすることができ、利便性を高めることができる。   According to the first aspect of the invention, the wireless LAN communication means can alternatively connect a wireless LAN line between the first connection partner terminal and the second connection partner terminal. The control unit controls connection and disconnection of the wireless LAN line in the wireless LAN communication unit. Here, the control means operates the wireless LAN communication means as a station in the infrastructure mode by setting the first connection partner terminal that operates as an access point in the infrastructure mode as the connection destination of the wireless LAN line. When it is detected that a connection request for the wireless LAN line between the second connection partner terminal and the wireless LAN communication unit is generated, the wireless LAN line is connected between the first connection partner terminal and the wireless LAN communication unit. The wireless LAN line is automatically connected between the second connection partner terminal and the wireless LAN communication means on the condition that is disconnected. As a result, when the connection partner terminal is switched from the first connection partner terminal to the second connection partner terminal, an operation by the user for switching the operation of the wireless LAN communication terminal can be eliminated. Can increase the sex.

さて、Ｗｉ−Ｆｉ通信等のＩＥＥＥ８０２．１１の無線ＬＡＮ通信に準拠した規格では、Ｗｉ−Ｆｉ回線を接続する動作モードの１つとしてインフラストラクチャモード（Infrastructure Mode）が規定されている。インフラストラクチャモードでは、接続端末同士の一方がアクセスポイントとして動作すると共に他方がステーションとして動作することで、無線ＬＡＮ回線を接続可能となり、無線ＬＡＮ通信が成立する。又、Ｗｉ−Ｆｉ通信に準拠した規格では、インフラストラクチャモードに加えてダイレクトモード（Direct Mode）（Ｗｉ−Ｆｉダイレクト）が規定されている。ダイレクトモードでは、接続端末同士の双方がＰ２Ｐ（Peer to Peer）デバイスとして対等に動作することで、Ｗｉ−Ｆｉ回線を接続可能となり、Ｗｉ−Ｆｉ通信が成立する。   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.

次に、上記した構成の作用について、図２から図５も参照して説明する。ここでは、Ｗｉ−Ｆｉルータ３のＷｉ−Ｆｉ通信部３３がインフラストラクチャモードのアクセスポイントとして動作している場合を前提とし（Ａ１）、ユーザが無線ＬＡＮ通信端末２を宅内で使用してから車内に持ち込んで使用する状況で、無線ＬＡＮ通信端末２、Ｗｉ−Ｆｉルータ３及び車載機４のそれぞれが行う処理について説明する。   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.

無線ＬＡＮ通信端末２において、制御部２１は、無線ＬＡＮ通信端末２とＷｉ−Ｆｉルータ３とがＷｉ−Ｆｉ通信圏内に存在していれば、Ｗｉ−Ｆｉルータ３との間でＷｉ−Ｆｉ通信の相互認証を行う。制御部２１は、Ｗｉ−Ｆｉルータ３との間でＷｉ−Ｆｉ通信の相互認証が成立したと判定すると、Ｗｉ−Ｆｉルータ３のＷｉ−Ｆｉ通信部３３の動作状態を判定する。制御部２１は、Ｗｉ−Ｆｉルータ３のＷｉ−Ｆｉ通信部３３がインフラストラクチャモードのアクセスポイントとして動作していると判定すると、Ｗｉ−Ｆｉ通信部２３をインフラストラクチャモードのステーションとして動作させることで（Ｂ１）、Ｗｉ−Ｆｉ通信部２３とＷｉ−Ｆｉ通信部３３との間でＷｉ−Ｆｉ回線をインフラストラクチャモードにより接続させる。これにより、制御部２１は、Ｗｉ−Ｆｉルータ３との間でＷｉ−Ｆｉ通信を成立させる（Ａ２、Ｂ２）。   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).

これ以降、ユーザが無線ＬＡＮ通信端末２を宅内から持ち出して車内に持ち込んだ場合を説明する。無線ＬＡＮ通信端末２において、制御部２１は、ユーザが無線ＬＡＮ通信端末２を宅内から持ち出したことで、無線ＬＡＮ通信端末２がＷｉ−Ｆｉルータ３のＷｉ−Ｆｉ通信圏内から外れると、Ｗｉ−Ｆｉ通信部２３とＷｉ−Ｆｉ通信部３３との間で接続させていたＷｉ−Ｆｉ回線を切断させる。一方、車載機４において、制御部４１は、ユーザが車両に乗車してＡＣＣスイッチ６をオフからオンに切換えたことをＡＣＣ信号により検知すると、Ｂｌｕｅｔｏｏｔｈ接続要求をＢｌｕｅｔｏｏｔｈ通信部４３から送信させる。   Hereinafter, a case where the user takes out the wireless LAN communication terminal 2 from the home and brings it into the car will be described. In the wireless LAN communication terminal 2, when the user takes the wireless LAN communication terminal 2 out of the home and the wireless LAN communication terminal 2 goes out of the Wi-Fi communication area of the Wi-Fi router 3, the control unit 21 The Wi-Fi line connected between the Fi communication unit 23 and the Wi-Fi communication unit 33 is disconnected. On the other hand, in the in-vehicle device 4, the control unit 41 transmits a Bluetooth connection request from the Bluetooth communication unit 43 when detecting that the user gets on the vehicle and switches the ACC switch 6 from OFF to ON based on the ACC signal.

無線ＬＡＮ通信端末２において、制御部２１は、ユーザが無線ＬＡＮ通信端末２を車内に持ち込んだことで、無線ＬＡＮ通信端末２が車載機４のＢｌｕｅｔｏｏｔｈ通信圏内に進入し、車載機４のＢｌｕｅｔｏｏｔｈ通信部４３から送信されたＢｌｕｅｔｏｏｔｈ接続要求をＢｌｕｅｔｏｏｔｈ通信部２４により受信したと判定すると、車載機４との間でＢｌｕｅｔｏｏｔｈ通信の相互認証を行う。制御部２１は、車載機４との間でＢｌｕｅｔｏｏｔｈ通信の相互認証が成立したと判定すると、Ｂｌｕｅｔｏｏｔｈ通信部２４とＢｌｕｅｔｏｏｔｈ通信部４３との間でＢｌｕｅｔｏｏｔｈ回線を接続させる。これにより、制御部２１は、車載機４との間でＢｌｕｅｔｏｏｔｈ通信を成立させる（Ｂ３、Ｃ２）。   In the wireless LAN communication terminal 2, the control unit 21 causes the wireless LAN communication terminal 2 to enter the Bluetooth communication area of the in-vehicle device 4 when the user brings the wireless LAN communication terminal 2 into the vehicle, and the Bluetooth communication of the in-vehicle device 4. 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).

そして、制御部２１は、車載機４との間でＢｌｕｅｔｏｏｔｈ通信を成立させた後に、Ｗｉ−Ｆｉ切断要求をＷｉ−Ｆｉ通信部２３から送信させる。この場合、制御部２１は、無線ＬＡＮ通信端末２がＷｉ−Ｆｉルータ３のＷｉ−Ｆｉ通信圏内から外れていなくても、Ｗｉ−Ｆｉ切断要求をＷｉ−Ｆｉ通信部２３から送信させることで、Ｗｉ−Ｆｉ通信部２３とＷｉ−Ｆｉ通信部３３との間で接続させていたＷｉ−Ｆｉ回線を切断させる。又、この場合、制御部２１は、Ｗｉ−Ｆｉ通信部２３をインフラストラクチャモードのステーションとして動作させたままである。そのため、車載機４のＷｉ−Ｆｉ通信部４２がインフラストラクチャモードのステーションとして動作している場合やダイレクトモードのＰ２Ｐデバイスとして動作していると、無線ＬＡＮ通信端末２と車載機４との間でＷｉ−Ｆｉ通信を成立させることができない。制御部２１は、この点を考慮し、以下の処理を行うことで、無線ＬＡＮ通信端末２と車載機４との間でＷｉ−Ｆｉ通信を成立させる。ここでは、Ｗｉ−Ｆｉ通信を成立させる方法として、
（１）インフラストラクチャモードの機能（役割）を切換える処理
（２）動作モードを切換える処理
について順次説明する。 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. In this case, the control unit 21 keeps the Wi-Fi communication unit 23 operating as an infrastructure mode station. Therefore, when the Wi-Fi communication unit 42 of the in-vehicle device 4 is operating as an infrastructure mode station or as a direct mode P2P device, between the wireless LAN communication terminal 2 and the in-vehicle device 4. Wi-Fi communication cannot be established. In consideration of this point, the control unit 21 establishes Wi-Fi communication between the wireless LAN communication terminal 2 and the in-vehicle device 4 by performing the following processing. Here, as a method of establishing Wi-Fi communication,
(1) Processing for switching the function (role) of the infrastructure mode (2) Processing for switching the operation mode will be sequentially described.

（１）インフラストラクチャモードの機能を切換える処理
制御部２１は、無線ＬＡＮ通信端末２と車載機４との間でＢｌｕｅｔｏｏｔｈ通信を成立させると（Ｂｌｕｅｔｏｏｔｈ回線の接続を正常に完了すると）、無線ＬＡＮ通信端末２と車載機４との間でＷｉ−Ｆｉ通信の接続要求が発生したと判定し（第１の手順を実行し）、車載機４のＷｉ−Ｆｉ通信部４２の動作状態をＢｌｕｅｔｏｏｔｈ通信により取得して判定する。制御部２１は、新たなＷｉ−Ｆｉの接続先である車載機４のＷｉ−Ｆｉ通信部４２がインフラストラクチャモードのステーションとして動作している場合であれば（Ｃ１）、Ｗｉ−Ｆｉ通信部２３の動作モードをインフラストラクチャモードとしたまま、そのインフラストラクチャモードの機能をステーションからアクセスポイントに切換え（Ｂ４）、Ｗｉ−Ｆｉ通信部２３をインフラストラクチャモードのアクセスポイントとして動作させる（Ｂ５）。 (1) Processing for switching the function of the infrastructure mode When the control unit 21 establishes Bluetooth communication between the wireless LAN communication terminal 2 and the in-vehicle device 4 (when connection of the Bluetooth line is normally completed), the wireless LAN communication It is determined that a connection request for Wi-Fi communication has occurred between the terminal 2 and the vehicle-mounted device 4 (execution of the first procedure), and the operation state of the Wi-Fi communication unit 42 of the vehicle-mounted device 4 is determined by Bluetooth communication. 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).

次いで、制御部２１は、「Ｐｒｏｂｅ Ｒｅｑｕｅｓｔ」をＷｉ−Ｆｉ通信部２３から車載機４のＷｉ−Ｆｉ通信部４２に送信させる。制御部２１は、車載機４のＷｉ−Ｆｉ通信部４２から送信された「Ｐｒｏｂｅ Ｒｅｓｐｏｎｓｅ」を車載機４のＷｉ−Ｆｉ通信部４２からＷｉ−Ｆｉ通信部２３により受信すると、車載機４との間でＷｉ−Ｆｉ通信の相互認証を行う。そして、制御部２１は、車載機４との間でＷｉ−Ｆｉ通信の相互認証が成立したと判定すると、Ｗｉ−Ｆｉ通信部２３とＷｉ−Ｆｉ通信部４２との間でＷｉ−Ｆｉ回線をインフラストラクチャモードにより接続させる。これにより、制御部２１は、車載機４との間でＷｉ−Ｆｉ通信を成立させる（Ｂ６、Ｃ３）（第２の手順を実行する）。   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).

以上に説明したように、図３にも示すように、車載機４のＷｉ−Ｆｉ通信部４２がインフラストラクチャモードのステーションとして動作している状況でユーザが無線ＬＡＮ通信端末２を車内に持ち込むと、ユーザがＡＣＣスイッチ６をオフからオンに切換えたことでＢｌｕｅｔｏｏｔｈ通信が成立したことを契機とし、無線ＬＡＮ通信端末２がＷｉ−Ｆｉ通信部２３の動作モードをインフラストラクチャモードとしたまま、そのインフラストラクチャモードの機能をステーションからアクセスポイントに切換える。これにより、ユーザがインフラストラクチャモードの機能や動作モードを切換える操作を行わなくとも（手動で行わなくとも）、宅内でのＷｉ−Ｆｉ通信から車内でのＷｉ−Ｆｉ通信へとシームレスに（自動で）切換えることができる。   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）動作モードを切換える処理
この場合も、制御部２１は、無線ＬＡＮ通信端末２と車載機４との間でＢｌｕｅｔｏｏｔｈ通信を成立させると、無線ＬＡＮ通信端末２と車載機４との間でＷｉ−Ｆｉ通信の接続要求が発生したと判定し（第１の手順を実行し）、車載機４のＷｉ−Ｆｉ通信部４２の動作状態をＢｌｕｅｔｏｏｔｈ通信により取得して判定する。制御部２１は、新たなＷｉ−Ｆｉの接続先である車載機４のＷｉ−Ｆｉ通信部４２がダイレクトモードのＰ２Ｐデバイスとして動作している場合であれば（Ｃ１１）、Ｗｉ−Ｆｉ通信部２３の動作モードをインフラストラクチャモードからダイレクトモードに切換え（Ｂ１１）、Ｗｉ−Ｆｉ通信部２３をダイレクトモードのＰ２Ｐデバイスとして動作させる（Ｂ１２）。 (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).

次いで、制御部２１は、「Ｆｉｎｄ」をＷｉ−Ｆｉ通信部２３と車載機４のＷｉ−Ｆｉ通信部４２との間で送受信させ、車載機４との間でＷｉ−Ｆｉ通信の相互認証を行う。そして、制御部２１は、車載機４との間でＷｉ−Ｆｉ通信の相互認証が成立したと判定すると、Ｗｉ−Ｆｉ通信部２３とＷｉ−Ｆｉ通信部４２との間でＷｉ−Ｆｉ回線をダイレクトモードにより接続させる。これにより、制御部２１は、車載機４との間でＷｉ−Ｆｉ通信を成立させる（Ｂ１３、Ｃ１２）（第２の手順を実行する）。   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).

以上に説明したように、図５にも示すように、車載機４のＷｉ−Ｆｉ通信部４２がダイレクトモードのＰ２Ｐデバイスとして動作している状況でユーザが無線ＬＡＮ通信端末２を車内に持ち込むと、ユーザがＡＣＣスイッチ６をオフからオンに切換えたことでＢｌｕｅｔｏｏｔｈ通信が成立したことを契機とし、無線ＬＡＮ通信端末２がＷｉ−Ｆｉ通信部２３の動作モードをインフラストラクチャモードからダイレクトモードに切換える。これにより、この場合も、ユーザがインフラストラクチャモードの機能や動作モードを切換える操作を行わなくとも（手動で行わなくとも）、宅内でのＷｉ−Ｆｉ通信から車内でのＷｉ−Ｆｉ通信へとシームレスに（自動で）切換えることができる。   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).

尚、以上は、Ｗｉ−Ｆｉ通信を一例として説明したが、接続端末同士の間で無線ＬＡＮ回線をインフラストラクチャモードにより接続可能なシステムであれば、上記した「（１）インフラストラクチャモードの機能を切換える処理」を他の無線ＬＡＮ通信にも適用することできる。   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.

以上に説明したように本実施形態によれば、無線ＬＡＮ通信端末２において、Ｗｉ−Ｆｉ通信の接続先をＷｉ−Ｆｉルータ３から車載機４に切換える場合に、そのインフラストラクチャモードの機能や動作モードを自動で切換えるようにした。これにより、ユーザがインフラストラクチャモードの機能や動作モードを切換える操作を不要とし、宅内でのＷｉ−Ｆｉ通信から車内でのＷｉ−Ｆｉ通信へとシームレスに切換えることができ、利便性を高めることができる。   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.

即ち、車載機４のＷｉ−Ｆｉ通信部４２がインフラストラクチャモードのステーションとして動作している状況では、Ｗｉ−Ｆｉ通信部２３の動作モードをインフラストラクチャモードとしたまま、インフラストラクチャモードの機能をステーションからアクセスポイントに自動で切換えるようにした。これにより、ユーザがインフラストラクチャモードの機能をステーションからアクセスポイントに切換える操作を不要とすることができる。又、車載機４のＷｉ−Ｆｉ通信部４２がダイレクトモードのＰ２Ｐデバイスとして動作している状況では、動作モードをインフラストラクチャモードからダイレクトモードに自動で切換えるようにした。これにより、ユーザが動作モードをインフラストラクチャモードからダイレクトモードに切換える操作を不要とすることができる。   That is, in a situation where the Wi-Fi communication unit 42 of the in-vehicle device 4 is operating as an infrastructure mode station, the infrastructure mode function is set to the station while the operation mode of the Wi-Fi communication unit 23 is set to the infrastructure mode. 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.

又、無線ＬＡＮ通信端末２において、接続先をＷｉ−Ｆｉルータ３から車載機４に切換える場合に、Ｗｉ−Ｆｉ切断要求を送信するようにした。これにより、Ｗｉ−Ｆｉ切断要求を送信することで、Ｗｉ−Ｆｉルータ３との間で接続させていたＷｉ−Ｆｉ回線を確実に切断させることができ、Ｗｉ−Ｆｉ回線をＷｉ−Ｆｉルータ３との間で接続させたままでいる（切断させていない）ことが原因で想定される不具合を未然に回避することができる。   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).

又、無線ＬＡＮ通信端末２において、ユーザが車両に乗車してＡＣＣスイッチ６をオフからオンに切換え、Ｂｌｕｅｔｏｏｔｈ回線を車載機４との間で接続したことを契機として接続先をＷｉ−Ｆｉルータ３から車載機４に切換えるようにした。これにより、ユーザが車両に乗車してＡＣＣスイッチ６をオフからオンに切換えた直後に車内でＷｉ−Ｆｉ回線を接続させることができ、車内でのＷｉ−Ｆｉ通信を利用したアプリケーションをユーザに提供することができる。   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.

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 is good also as a structure which determines with having generate | occur | produced. 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.

With this configuration, it is possible to select whether to permit or prohibit seamless switching from Wi-Fi communication in the home to Wi-Fi communication in the vehicle. For example, by determining the Bluetooth ID assigned to the in-vehicle device 4, the infrastructure mode and the operation mode may be switched only when a Bluetooth line is connected to the in-vehicle device 4 to which a specific Bluetooth ID is assigned. good. Further, for example, a Bluetooth class of device (CoD) (24-bit value indicating what type of device the Bluetooth device is) assigned to the in-vehicle device 4 is determined, and a specific value is assigned.
