Description

  The present invention relates to an information processing apparatus, a wireless LAN connection control method, and a program, and in particular, a wireless LAN connection between a removable device having a WAN communication function and a wireless communication LAN function such as a mobile router and an information processing apparatus such as a PC. The present invention relates to a technique preferably applied to connection control.

  In recent years, routers having a plurality of network connection functions such as a WAN communication function (for example, communication to a 3G network) and a wireless LAN communication function have been known. For example, when a user uses a portable terminal other than a PC, such as a mobile phone or a PDA, the router is usually operated alone and connected to the Internet using the WAN communication function of the router, or the wireless communication LAN function is used. be able to. In addition, when the user uses a PC, communication via the 3G network can be performed using the communication WAN function of the router. In this case, the router and the PC are connected to function as an adapter.

  When the router is used alone, the user needs to care about the battery life, but when connected to the PC, the user can receive power supply from the PC, which is advantageous in terms of battery life. In addition, if the router is small enough to be stored in the PC body, it can be connected by attaching it to the PC instead of using a USB cable. In this way, the router is attached to the PC and integrated with the PC. In the case of becoming a mobile phone, there is an advantage in carrying that both sides are not bulky.

  On the other hand, when the router and the PC are connected by cable or the router is stored in the PC, there are the following problems. That is, if the router and the PC are connected by cable or the router is stored in the PC, the router's WAN communication function is recognized as a local device of the PC, so the router's routing function stops, and the above-described portable terminal other than the PC Will not be able to connect to the Internet through a router.

Although it is not inevitable that the WAN communication function of the router is recognized as a local device of the PC when the cable is connected or stored, there are the following two points as background, and such a router product is common.
1. If you have both a PC with a built-in WAN communication function and a router with a WAN communication function, you can make a communication contract for 2 terminals (communication charges are high) or share contract information such as SIM cards between the 2 terminals ( Therefore, the WAN communication module itself is used as both a personal computer and a router.
2. Even after the router and the PC are physically connected, it is physically possible to continue to operate the routing function, but the physically connected PC and router will bother to communicate with each other via a wireless LAN. Will waste your battery.

  For example, Patent Document 1 discloses a technique for compensating for communication between LAN-WAN-LAN terminals without changing terminal routing settings even if a failure occurs in one IP router. In this technology, the LAN-WAN-LAN connection IP router is duplicated, the secondary IP router monitors the state of the primary IP router, and when the primary IP router fails, the secondary IP router takes over the routing information and address of the primary IP router. In this way, automatic duplication of the IP router is realized, and communication between terminals is compensated.

Each means may be realized by software as described above, or may be realized by hardware using a circuit or the like.

  The connection detection unit 110 detects the connection state between the mobile router 20 and the PC 10. That is, information on the connection status of peripheral devices detected by the OS is monitored, and it is detected that the mobile router 20 is connected to the PC 10 via the USB IF 16 and that the mobile router 20 is separated from the PC 10.

  The wireless LAN state detection unit 120 detects the state of the wireless LAN communication function of the PC 10. That is, information on the operating status of the wireless LAN communication function detected by the OS is monitored to detect whether the wireless LAN communication function of the PC 10 is in an operable state or inoperable state.

  The wireless LAN setting unit 130 performs the wireless LAN setting of the PC 10 based on the connection state of the mobile router 20 detected by the connection detection unit 110 and the state of the wireless LAN communication function of the PC 10 detected by the wireless LAN state detection unit 120.

  FIG. 4 is a functional configuration diagram of the mobile router according to the present embodiment. The mobile router 20 of the present embodiment includes a power supply control circuit 21, a signal switching circuit 22, a wireless LAN setting storage unit 23, a router battery 24, a router control unit 25, a wireless LAN module 26, and a 3G communication module 27.

  The power control circuit 21 is a circuit that controls the power of the mobile router 20 and switches the power according to the connection state of the mobile router 20. When connected to the PC 10, the power (USB power) of the PC 10 is supplied to the mobile router 20, and when not connected to the PC, power is supplied from the router battery 24.

  The signal switching circuit 22 is a circuit that switches signals transmitted through the mobile router 20, and switches signals according to the state of the wireless LAN communication function of the PC 10 (assuming connection to the PC). When the wireless LAN communication function of the PC 10 is in an operable state (wireless LAN on state), the USB signal from the PC 10 is transmitted through the mobile router 20, and the wireless LAN communication function of the PC 10 is in an inoperable state (wireless LAN off state). ), The signal is transmitted only within the mobile router 20. As a result of the signal switching by the signal switching circuit 22, the PC 10 performs the routing control when the wireless LAN is in the on state (the left diagram in FIG. 4), and the router control unit 25 performs the routing control when the PC 10 is in the wireless LAN off state. (Right figure of FIG. 4). Note that the wireless LAN off state includes a case where the PC power is on and the wireless LAN communication function is off, and a case where the PC power is off.

  The wireless LAN setting storage unit 23 stores wireless LAN setting information of the mobile router 20. The router battery 24 is a battery used when the mobile router 20 operates alone.

The left figure shows the operation when the mobile router 20 is taken out, the central figure shows the operation when the PC 10 is stored and the wireless LAN is off, and the right figure shows the operation when the PC 10 is stored and when the wireless LAN is on.

  When the mobile router 20 is taken out, the mobile router 20 performs a routing operation alone, so power is supplied from its own battery and the routing control is also performed by itself. The mobile router 20 enables communication using the 3G function or the wireless LAN communication function to the mobile terminal 30, and enables communication using the 3G function to the PC 10 having the wireless LAN communication function.

  When storing and when the wireless LAN of the PC 10 is OFF, power is supplied from the PC 10 and routing control is performed by itself. That is, the mobile router 20 uses the PC 10 as an extended battery, and the routing operation is the same as that when operating alone.

  When stored and when the wireless LAN of the PC 10 is on, the mobile router 20 receives power supply and routing control from the PC 10. The mobile router 20 stops the wireless LAN communication function and the routing control, and entrusts the routing control using the 3G function to the PC 10 (see the left diagram in FIG. 4). That is, the PC 10 functions as a router using the mobile router 20 as a 3G adapter. As a result, the mobile terminal 30 performs 3G communication using the 3G function of the mobile router 20 and performs wireless LAN communication using the wireless LAN communication function of the PC 10.

The control unit 25 performs module IF control (process (8)) by the signal switching circuit 22. The wireless LAN setting notification (process (9)) is performed by the wireless LAN setting unit 130 of the PC 10 after the routing control is switched from the mobile router 20 to the PC 10.

  Note that the wireless LAN setting information notified by the wireless LAN setting notification (process (9)) includes network identification information, security setting information, and SoftAP setting information. These are pieces of information that are unfamiliar to ordinary users and are not easily felt, and can be said to be one of the factors complicating the user's setting of the wireless LAN.

  FIG. 7 is an explanatory diagram of the wireless LAN communication function switching process and the wireless LAN setting process according to the embodiment of the present invention. The process based on the connection state of the mobile router 20 and the state of the wireless LAN communication function of the PC 10 is divided into cases. It is expressed. This is described using each process described in FIG.

<When mounted with PC side wireless LAN off (Case (A))>
A case where the PC is turned off and a case where the PC is turned on and the wireless LAN communication function on the PC side is turned off will be described separately. When the mobile router 20 is mounted in the PC power off state, the mobile router 20 detects that the power control circuit 21 is mounted on the PC 10 and is in the PC power off state (process (5)), and receives power supply from the PC 10 for router use. The battery 24 starts to be charged and operated by the power source of the PC 10 (process (7)).

  When the PC power supply is on and the wireless LAN communication function on the PC side is turned off, it is not shown in FIG. In the mobile router 20, the power supply control circuit 21 detects attachment to the PC 10 (process (5)), and in the PC 10, the connection detection unit 110 detects attachment of the mobile router 20 (process (1)). In the PC 10, the wireless LAN state detection means 120 detects the PC-side wireless LAN off state and notifies the information mobile router 20 (process (2)). In the mobile router 20, the router control unit 25 acquires information on the PC-side wireless LAN off state (process (6)), and upon receiving this information, the power control circuit 21 charges the router battery 24 using the power from the PC 10. Is started (process (7)).

<When removed with PC side wireless LAN off (Case (B))>
When the mobile router 20 is removed in the PC power off state, the mobile router 20 detects that the power control circuit 21 has been removed from the PC 10 (process (5)), and the router battery is charged from the charging and routing operations using the power of the PC 10. Switching to driving using a power supply (process (7)).

<When mounted with PC-side wireless LAN on (Case (C))>
When the mobile router 20 is mounted while the PC-side wireless LAN is on, the power control circuit 21 detects the mounting on the PC 10 in the mobile router 20 (process (5)), and the connection detection means 110 detects the mounting of the mobile router 20 in the PC 10 ( Process (1)). In the PC 10, the wireless LAN state detection means 120 detects the PC-side wireless LAN on state and notifies the information mobile router 20 (process (2)).

  In the mobile router 20, the router control unit 25 acquires information on the PC-side wireless LAN on state (process (6)), and upon receiving this information, the power supply control circuit 21 uses the power supply from the PC 10 to charge the router battery 24. And the operation using the power supply of the PC 10 is performed, but the power supply to the router control unit 25 and the wireless LAN module 26 is stopped (process (7)). After the router control unit 25 is turned off, the signal switching circuit 22 switches so that the USB signal of the PC 10 is transmitted to each component (circuit, module, etc.) so that the PC 10 performs routing control. As a result, the control of the 3G communication module 27 is switched from the mobile router 20 to the PC 10 (process (8)).

  In the PC 10, the wireless LAN setting unit 130 accesses the wireless LAN setting storage unit 23 via the signal switching circuit 22 and reads the wireless LAN setting information of the mobile router 20 (process (9), process (3)). Then, the wireless LAN setting of the PC 10 is performed using the read wireless LAN setting information of the mobile router 20 (process (4)). That is, the wireless LAN setting information is inherited between the PC 10 and the mobile router 20, and the wireless LAN setting is switched. As a result, a mobile terminal or the like that is connected to the mobile router 20 and performs wireless LAN communication seamlessly. Wireless LAN communication can be continued through the PC 10.

<When removed while PC side wireless LAN is on (Case (D))>
When the mobile router 20 is removed while the PC-side wireless LAN is on, the mobile router 20 detects that the power supply control circuit 21 has been removed from the PC 10 (process (5)), and the router uses the charging and routing operations using the power supply of the PC 10 for the router. While switching to driving using the battery power supply, power supply to the router control unit 25 and the wireless LAN module 26 is started (process (7)). That is, the mobile router 20 can be operated alone.

  After the router control unit 25 is turned on, the signal switching circuit 22 blocks the USB signal of the PC 10 and does not transmit it to each component (circuit, module, etc.) so that the router control unit 25 performs routing control. Switch. Thereby, the control of the 3G communication module 27 is switched from the PC 10 to the mobile router 20 (router control unit 25), and the connection by the portable terminal or the like is switched from the wireless LAN communication function of the PC 10 to the wireless LAN communication function of the mobile router 20 (processing ( 8)).

  On the other hand, the PC 10 detects that the mobile router 20 has been removed by the connection detection unit 110 (process (1)). In response to this detection result, the wireless LAN setting means 130 returns the wireless LAN setting from the setting content of the mobile router 20 to the setting content of the PC 10 (process (4)). That is, the wireless LAN setting is performed using the wireless LAN setting information of the PC 10. This is because after the mobile router 20 is removed, the PC 10 performs wireless LAN communication using its own wireless LAN communication function with respect to a mobile terminal or the like connected to the PC 10.

<When the PC side wireless LAN communication function is turned on from off with the router attached (Case (E))>
The PC 10 detects the change in the state of the PC-side wireless LAN communication function from OFF to ON by the wireless LAN state detection unit 120 and notifies the information mobile router 20 that the PC-side wireless LAN communication function is in the ON state ( Process (2)). In the mobile router 20, the router control unit 25 acquires information on the PC-side wireless LAN on state (process (6)), and the power control circuit 21 receives the information to supply power to the router control unit 25 and the wireless LAN module 26. Supply is stopped (process (7)).

  After the router control unit 25 is turned off, the signal switching circuit 22 switches so that the USB signal of the PC 10 is transmitted to each component (circuit, module, etc.) so that the PC 10 performs routing control. As a result, the control of the 3G communication module 27 is switched from the mobile router 20 to the PC 10 (process (8)).

  In the PC 10, the wireless LAN setting unit 130 accesses the wireless LAN setting storage unit 23 via the signal switching circuit 22 and reads the wireless LAN setting information of the mobile router 20 (process (9), process (3)). Then, the wireless LAN setting of the PC 10 is performed using the read wireless LAN setting information of the mobile router 20 (process (4)). That is, the wireless LAN setting information is inherited between the PC 10 and the mobile router 20, and the wireless LAN setting is changed.

<When the PC side wireless LAN communication function is switched from ON to OFF with the router attached (Case (F))>
In the PC 10, the wireless LAN state detection unit 120 detects a change in the state of the PC-side wireless LAN communication function from on to off, and notifies the information mobile router 20 that the PC-side wireless LAN communication function is in the off state ( Process (2)). The mobile router 20 receives information on the PC-side wireless LAN off state (process (6)), and the power supply control circuit 21 starts supplying power to the router controller 25 and the wireless LAN module 26 (process (7)).

  After the router control unit 25 is turned on, the signal switching circuit 22 blocks the USB signal of the PC 10 and does not transmit it to each component (circuit, module, etc.) so that the router control unit 25 performs routing control. Switch. Thereby, the control of the 3G communication module 27 is switched from the PC 10 to the mobile router 20 (router control unit 25), and the connection by the portable terminal or the like is switched from the wireless LAN communication function of the PC 10 to the wireless LAN communication function of the mobile router 20 (processing ( 8)).

  On the other hand, the PC 10 receives the detection result from the wireless LAN state detection unit 120 (that the PC side wireless LAN is off), and the wireless LAN setting unit 130 changes the wireless LAN setting from the setting contents of the mobile router 20 to the setting of the PC 10. Return to contents (process (4)). That is, the wireless LAN setting is performed using the wireless LAN setting information of the PC 10.

  There are several possible methods for taking over the wireless LAN setting information (wireless LAN setting notification (process (9)) and wireless LAN setting acquisition (process (3)). The first method is shown in the above description. In addition, a function unit for storing wireless LAN setting information is provided independently (the wireless LAN setting storage unit 23), and writing of the wireless LAN setting information is performed on the router side, and reading is performed on the PC side. It is.

  The second method is to hold the wireless LAN setting information in the router control unit 25, switch the router control from the USB host to the USB device, read out the wireless LAN setting information from the PC side, and then read out the router control unit This is a method of stopping the power supply to 25. In this method, it is not necessary to provide an independent function unit for storing the wireless LAN setting information.

  The third method uses wireless instead of USB signals for exchanging wireless LAN setting information. Before the power supply of the router control unit 25 is stopped, the mobile router 20 and the PC 10 are connected by wireless LAN, and wireless In this method, the router control unit 25 is turned off after the LAN setting information is transferred. This method also eliminates the need to provide an independent function unit for storing wireless LAN setting information, as in the second method.
