According to this configuration, it is possible to newly construct a second wireless network in which the communication device inevitably operates as a master station state. As a result, the communication device can appropriately perform wireless communication of the target data with the mobile terminal by operating as a master station state in the newly constructed second wireless network.

The control unit may further include a receiving unit that receives specific information from the mobile terminal by using the first type interface. In the second case, the communication execution unit is a specific wireless setting for the communication device to belong to the second target network when the mobile terminal currently belongs to the second target network.

(First Example)
(Communication system configuration)
As shown in FIG. 1, the communication system 2 is referred to as a multifunction device (hereinafter referred to as "MFP" (abbreviation of Multi-Function Peripheral)) 10, a mobile terminal 50, and an access point (hereinafter referred to as "AP"). ) 6 and PC8. The MFP 10 and the mobile terminal 50 can execute short-range wireless communication. Short-range wireless communication is wireless communication according to the NFC method. In this embodiment, wireless communication according to the NFC method is executed based on the international standard of ISO / IEC21481 or 18092.

Further, the MFP 10 can execute wireless communication according to the WiFi Direct method described later. In the following, the WiFi Direct will be referred to as "WFD". In WFD, wireless communication is performed based on the IEEE (abbreviation of The Institute of Electrical and Electronics Engineers, Inc.) 802.11 standard and the equivalent standard (for example, 802.11a, 11b, 11g, 11n, etc.). Will be executed. The wireless communication system (that is, the standard of wireless communication) is different between the NFC system and the WFD system (hereinafter referred to as "WFD system"). Further, the communication speed of wireless communication according to the WFD method is higher than the communication speed of wireless communication according to the NFC method.

For example, the MFP 10 can construct a WFD network by establishing a connection with the mobile terminal 50 (hereinafter referred to as "WFD connection") according to the WFD method. Similarly, the MFP 10 can construct a WFD network by establishing a WFD connection with the PC 8.

The PC8, the MFP10, and the mobile terminal 50 can further perform wireless communication according to a normal Wi-Fi (for example, IEEE802.11) method different from the WFD method. Generally speaking, the wireless communication according to the normal Wi-Fi is the wireless communication in which the AP6 is used, and the wireless communication according to the WFD method is the wireless communication in which the AP6 is not used. For example, the MFP 10 can belong to a normal Wi-Fi network by establishing a connection with AP6 (hereinafter referred to as "normal Wi-Fi connection") according to normal Wi-Fi. The MFP 10 can execute wireless communication with other devices (for example, PC8, mobile terminal 50) that normally belong to the Wi-Fi network via the AP6. The NFC method and the normal Wi-Fi method (hereinafter referred to as "normal Wi-Fi method") differ in the wireless communication method (that is, the standard of wireless communication). In addition, the communication speed of Wi-Fi is usually faster than the communication speed of NFC.

(WFD)
WFD is a standard developed by the Wi-Fi Alliance. The WFD is described in the "Wi-Fi Peer-to-Peer (P2P) Technical Specification Version 1.1" created by the Wi-Fi Alliance.

As described above, the PC8, the MFP10, and the mobile terminal 50 can each execute wireless communication according to the WFD method. Hereinafter, a device capable of executing wireless communication according to the WFD method is referred to as a "WFD compatible device". The WFD standard defines three states as the state of the WFD compatible device: the Group Owner state (hereinafter referred to as "G / O state"), the client state, and the device state. The WFD-compatible device can selectively operate in one of the above three states.

A WFD network is composed of a device in the G / O state and a device in the client state. In the WFD network, there can be only one device in the G / O state, but there can be one or more devices in the client state. The device in the G / O state manages one or more devices in the client state. Specifically, the device in the G / O state generates a management list in which the identification information (that is, the MAC address) of each of the devices in the one or more client states is described. When a device in the client state newly belongs to the WFD network, the device in the G / O state adds the identification information of the device to the management list, and when the device in the client state leaves the WFD network, the identification information of the device is added. Delete from the management list.

The device in the G / O state is the device registered in the management list, that is, the device in the client state (that is, the device belonging to the WFD network) and the target data (for example, the network layer of the OSI reference model). It is possible to execute wireless communication of data including information (print data, scan data, etc.). However, the device in the G / O state is the data for the unregistered device to belong to the WFD network (for example, the data not including the information of the network layer (Probe)) with the unregistered device not registered in the management list. Wireless communication of physical layer data such as Request signal and Probe Response signal) can be executed, but wireless communication of the above target data cannot be executed. For example, the MFP 10 in the G / O state is added to the management list. The print data can be wirelessly received from the registered mobile terminal 50 (that is, the mobile terminal 50 in the client state), but the print data cannot be wirelessly received from the device not registered in the management list.

Further, the device in the G / O state can relay wireless communication of target data (print data, scan data, etc.) between the devices in the G / O state. For example, when the mobile terminal 50 in the client state should wirelessly transmit the print data to another printer in the client state, the mobile terminal 50 first wirelessly transmits the print data to the MFP 10 in the G / O state. In this case, the MFP 10 wirelessly receives the print data from the mobile terminal 50 and wirelessly transmits the print data to the other printer described above. That is, the device in the G / O state can execute the function of the AP of the wireless network.

A WFD-compatible device that does not belong to the WFD network (that is, a device that is not registered in the management list) is a device in the device state. The device in the device state can execute wireless communication of data (data of the physical layer such as Probe Request signal, Probe Response signal, etc.) for belonging to the WFD network, but target data (print data, print data, etc.) via the WFD network. Wireless communication (scan data, etc.) is not possible.

In the following, a device that cannot execute wireless communication according to the WFD method but can normally execute wireless communication according to Wi-Fi is referred to as a "non-WFD compatible device". The "non-WFD compatible device" can also be called a "legacy device". A device that does not support WFD cannot operate in the G / O state. The device in the G / O state can describe the identification information of the device that does not support WFD in the management list.

(Configuration of MFP10)
The MFP 10 includes an operation unit 12, a display unit 14, a print execution unit 16, a scan execution unit 18, a wireless LAN interface (hereinafter, the interface is referred to as “I / F”) 20, an NFCI / F22, and the like. A control unit 30 is provided. The operation unit 12 includes a plurality of keys. The user can input various instructions to the MFP 10 by operating the operation unit 12. The display unit 14 is a display for displaying various information. The print execution unit 16 is a printing mechanism such as an inkjet method or a laser method. The scan execution unit 18 is a scanning mechanism for CCD, CIS, and the like.

The wireless LAN I / F 20 is an interface for the control unit 30 to execute wireless communication according to the WFD method and wireless communication according to normal Wi-Fi. The wireless LANI / F20 is physically one interface. However, the wireless LANI / F20 includes a MAC address used for wireless communication according to the WFD method (hereinafter referred to as "MAC address for WFD") and a MAC normally used for wireless communication according to Wi-Fi. Both an address (hereinafter referred to as a "normal Wi-Fi MAC address") and an address are assigned. More specifically, the wireless LAN I / F20 is usually assigned a MAC address for Wi-Fi in advance. The control unit 30 normally uses the Wi-Fi MAC address to generate the WFD MAC address, and assigns the WFD MAC address to the wireless LAN I / F 20. The MAC address for WFD is usually different from the MAC address for Wi-Fi. Therefore, the control unit 30 can simultaneously execute both the wireless communication according to the WFD method and the wireless communication according to the normal Wi-Fi via the wireless LANI / F20. As a result, it is possible that the MFP 10 belongs to the WFD network and usually belongs to the Wi-Fi network.

As for the device in the G / O state, not only the identification information of the WFD compatible device in the client state but also the identification information of the WFD non-compatible device can be described in the management list. That is, the device in the G / O state can establish a WFD connection with the device that does not support WFD. Generally speaking, the WFD connection is a wireless connection in which the WFD MAC address of the MFP 10 is used. The WFD network is a wireless network in which the MAC address for WFD of the MFP 10 is used. Similarly, the normal Wi-Fi connection is a wireless connection in which the normal Wi-Fi MAC address of the MFP 10 is used. Further, the normal Wi-Fi network is a wireless network in which the normal Wi-Fi MAC address of the MFP 10 is used.

The user can execute wireless communication according to the WFD method using the wireless LANI / F20 by changing the setting of the wireless LANI / F20 by operating the operation unit 12 (hereinafter, "WFD = ON"). (Called "mode") and a mode in which wireless communication according to the WFD method using wireless LANI / F20 cannot be executed (hereinafter referred to as "WFD = OFF mode"). Can be done. The mode setting unit 46 sets either the WFD = ON mode or the WFD = OFF mode according to the operation of the user. Specifically, the mode setting unit 46 stores the mode value representing the mode set by the user in the memory 34.

In the state where the WFDI / F = OFF mode is set, the control unit 30 executes each process according to the WFD method (for example, a process of setting the MFP 10 to the spontaneous G / O mode described later, G / O negotiation, etc.). Can not do it. In the state where WFDI / F = ON, the memory 34 stores a value indicating the current state (G / O state, client state, or device state) of the MFP 10 with respect to WFD.

The NFCI / F22 is an interface for the control unit 30 to execute wireless communication according to the NFC method. The NFCI / F22 is composed of a chip that is physically different from the W-FiI / F20.

The communication speed of wireless communication via wireless LANI / F20 (for example, the maximum communication speed is 11 to 454 Mbps) is the communication speed of wireless communication via NFCI / F22 (for example, the maximum communication speed is 100 to 424 Kbps). ) Faster. Further, the frequency of the carrier wave in wireless communication via wireless LANI / F20 (for example, 2.4 GHz band, 5.0 GHz band) is the frequency of the carrier wave in wireless communication via NFCI / F22 (for example, 13.56 MHz band). Is different. Further, when the distance between the MFP 10 and the mobile terminal 50 is about 10 cm or less, the control unit 30 can execute wireless communication with the mobile terminal 50 according to the NFC method via the NFCI / F22. On the other hand, regardless of whether the distance between the MFP 10 and the mobile terminal 50 is 10 cm or less or 10 cm or more (for example, about 100 m at the maximum), the control unit 30 uses the WFD method via the wireless LANI / F20. The wireless communication according to the above and the wireless communication according to the normal Wi-Fi can be executed with the mobile terminal 50. That is, the maximum distance that the MFP 10 can perform wireless communication with the communication destination device (for example, the mobile terminal 50) via the wireless LANI / F20 is such that the MFP 10 can communicate with the communication destination device via the NFCI / F22. Greater than the maximum distance that wireless communication can be performed.

The control unit 30 includes a CPU 32 and a memory 34. The CPU 32 executes various processes according to the program stored in the memory 34. When the CPU 32 executes the process according to the program, the functions of the respective units 40 to 46 are realized.

The memory 34 is composed of a ROM, a RAM, a hard disk, and the like. The memory 34 stores the above program executed by the CPU 32. The memory 34 includes a work area 38. The work area 38 is for executing communication of target data (for example, print data) via the WFD network with information indicating that the MFP 10 currently belongs to the WFD network when the MFP 10 currently belongs to the WFD network. Wireless settings (including authentication method, encryption method, password, wireless network SSID (Service Set Identifier), BSSID (Basic Service Set Identifier)) are stored. Further, the work area 38 includes information indicating that the MFP 10 currently belongs to the normal Wi-Fi network when the MFP 10 currently belongs to the normal Wi-Fi network, and target data via the normal Wi-Fi network. Stores wireless settings and settings for performing communication. The SSID of the WFD network is a network identifier for identifying the WFD network, and the SSID of the normal Wi-Fi network is usually a network identifier for identifying the Wi-Fi network. The BSSID of the WFD network is an identifier unique to the device in the G / O state (for example, the MAC address of the device in the G / O state), and the BSSID of the Wi-Fi network is usually an identifier unique to the AP (for example, AP unique). Identifier).

The work area 38 further stores a value indicating the current state of the WFD (one of the G / O state, the client state, and the device state) when the MFP 10 is operating according to the WFD method. The work area 38 further stores a mode value representing the WFD = ON mode or a mode value representing the WFD = OFF mode.

The user can set the MFP 10 to the spontaneous G / O mode by operating the operation unit 12. The spontaneous G / O mode is a mode in which the MFP 10 is maintained to operate in the G / O state. The work area 38 in the memory 34 further stores a value indicating whether or not the MFP 10 is set to the spontaneous G / O mode. As will be described in detail later, a WFD-compatible device in the device state normally operates in either the G / O state or the client state when establishing a WFD connection with another WFD-compatible device in the device state. Perform G / O negotiations to selectively determine what should be done. When the MFP 10 is set to the spontaneous G / O mode, the MFP 10 maintains its operation in the G / O state without executing the G / O negotiation.

(Configuration of mobile terminal 50)
The mobile terminal 50 is, for example, a mobile phone (for example, a smartphone), a PDA, a notebook PC, a tablet PC, a portable music playback device, a portable moving image playback device, or the like. The mobile terminal 50 includes two wireless interfaces, a wireless LAN I / F (that is, an interface for WFD and usually Wi-Fi) and an NFCI / F. Therefore, the mobile terminal 50 can execute wireless communication with the MFP 10 by using the wireless LAN I / F, and can execute wireless communication with the MFP 10 by using the NFCI / F. The mobile terminal 50 includes an application program for causing the MFP 10 to execute a function (for example, a printing function, a scanning function, etc.). The application program may be installed on the mobile terminal 50 from the server provided by the vendor of the MFP 10, or may be installed on the mobile terminal 50 from the media shipped together with the MFP 10.

Similar to the MFP 10, the mobile terminal 50 includes a work area 58 in the memory 54. When the mobile terminal 50 currently belongs to a WFD network or a normal Wi-Fi network, the work area 58 has wireless settings (authentication method, encryption method, password, wireless) for executing communication via the network. Stores the SSID and BSSID of the network). Further, when the mobile terminal 50 is operating according to the WFD method, the work area 58 sets a state value representing the state of the mobile terminal 50 (that is, any of the G / O state, the client state, and the device state). Store.

(Configuration of PC8)
The PC8 includes a wireless LANI / F (ie, an interface for WFD and usually Wi-Fi), but not an NFCI / F. Therefore, the PC 8 can execute communication with the MFP 10 by using the wireless LAN I / F, but cannot execute the wireless communication according to the NFC method. The PC 8 includes a driver program for causing the MFP 10 to execute processing (for example, printing processing, scanning processing, etc.). The driver program is usually installed on the PC 8 from the media shipped together with the MFP 10. However, in the modified example, the driver program may be installed on the PC8 from the server provided by the vendor of the MFP10.

(Structure of AP6)
The AP6 is not a device in the G / O state of the WFD, but a normal access point called a wireless access point or a wireless LAN router. The AP6 can usually establish a Wi-Fi connection with a plurality of devices. As a result, a normal Wi-Fi network including the AP6 and a plurality of devices is constructed. The AP6 receives data from one of a plurality of devices that normally belong to a Wi-Fi network, and transmits the data to the other one of the plurality of devices. That is, the AP6 normally relays communication between a pair of devices belonging to the Wi-Fi network.

The differences between the WFD G / O state device and the normal AP are as follows. That is, a device in the G / O state of the WFD is in a state other than the G / O state (that is, a client state) when the device leaves the WFD network to which the device currently belongs and newly belongs to another WFD network. Can work. On the other hand, a normal AP (that is, AP6) executes a function of relaying communication between a pair of devices regardless of which normal Wi-Fi network the AP belongs to, and cannot operate in the client state. ..

(Communication processing executed by MFP10)
The communication process executed by the MFP 10 will be described with reference to FIG. The control unit 30 executes communication processing when the power of the MFP 10 is turned on. In S2, the receiving unit 40 monitors the reception of NFC information by executing wireless communication according to the NFC method. The receiving unit 40 receives the NFC information via the NFCI / F22. Specifically, the receiving unit 40 monitors that an NFC communication session is established between the MFP 10 and the mobile terminal 50. While the power of the MFP 10 is turned on, the receiving unit 40 causes the NFCI / F22 to transmit radio waves for detecting a device capable of performing wireless communication according to the NFC method.

The user of the mobile terminal 50 activates the application program. By operating the mobile terminal 50, the user causes the mobile terminal 50 to generate NFC information including a process execution instruction (for example, a print instruction, a scan instruction) indicating a process to be executed by the MFP 10. The NFC information further includes the SSID and BSSID of the wireless network to which the mobile terminal 50 currently belongs, when the mobile terminal 50 currently belongs to the wireless network. When the mobile terminal 50 currently belongs to the wireless network, at least one wireless connection between the mobile terminal 50 and another device (for example, AP6, MFP10), a WFD connection and a normal Wi-Fi connection, is used. Is established.

When the user brings the mobile terminal 50 closer to the MFP 10 and the distance between the mobile terminal 50 and the MFP 10 becomes smaller than the distance that the radio waves reach each other (for example, 10 cm), the mobile terminal 50 receives the above radio waves from the MFP 10. Then, the response radio wave is transmitted to the MFP 10. As a result, the control unit 30 receives the response radio wave from the mobile terminal 50 and establishes an NFC communication session. When the NFC communication session is established, the mobile terminal 50 transmits the generated NFC information to the MFP 10.

When the NFC information is received (YES in S2), in S4, the determination unit 42 determines whether or not the MFP 10 currently belongs to the network. Specifically, the determination unit 42 stores at least one of the information indicating that it currently belongs to the WFD network and the information indicating that it currently belongs to the normal Wi-Fi network in the work area 38. If so, it is determined that the MFP 10 currently belongs to the wireless network (YES in S4), and the process proceeds to S6. On the other hand, the determination unit 42 determines when neither the information indicating that it currently belongs to the WFD network nor the information indicating that it currently belongs to the normal Wi-Fi network is stored in the work area 38, the MFP 10 Determines that does not currently belong to the wireless network (NO in S4) and proceeds to S8.

In S6, the determination unit 42 confirms whether or not the mobile terminal 50 currently belongs to the network to which the MFP 10 currently belongs. Specifically, the determination unit 42 first determines whether or not the SSID and BSSID of the network to which the mobile terminal 50 currently belongs are included in the NFC information. When the SSID and BSSID are not included in the NFC information, the determination unit 42 determines that the mobile terminal 50 does not currently belong to the network to which the MFP 10 currently belongs (NO in S6). According to this configuration, the MFP 10 can appropriately determine that the mobile terminal 50 does not currently belong to the network to which the MFP 10 currently belongs. When the SSID and BSSID of the network to which the mobile terminal 50 currently belongs are included in the NFC information, the determination unit 42 determines that the SSID and BSSID included in the wireless setting stored in the work area 38. Determines whether or not the SSID and BSSID included in the NFC information match.

If both the SSID and BSSID match, it is determined that the mobile terminal 50 currently belongs to the network to which the MFP 10 currently belongs (YES in S6), and the process proceeds to S7. On the other hand, if at least one of the SSID and the BSSID does not match, it is determined that the mobile terminal 50 does not currently belong to the network to which the MFP 10 currently belongs (NO in S6), and the process proceeds to S8. According to this configuration, the MFP 10 can appropriately determine whether or not the mobile terminal 50 currently belongs to the network to which the MFP 10 currently belongs. In S6, the determination unit 42 determines whether or not the SSIDs match, and also determines whether or not the BSSIDs match. As a result, the determination unit 42 can determine whether or not the MFP 10 and the mobile terminal 50 belong to the same wireless network constructed by the same AP. More specifically, one AP may construct a plurality of wireless networks by using a plurality of SSIDs. Therefore, if the BSSIDs match and the SSIDs do not match, there is a possibility that the MFP 10 and the mobile terminal 50 belong to different wireless networks constructed by the same AP. In this embodiment, by determining whether or not both the SSID and BSSID match, it is possible to more reliably determine whether or not the MFP 10 and the mobile terminal 50 belong to the same wireless network. In the modified example, it is not necessary to determine whether the SSIDs match in S6 and not determine whether the BSSIDs match. As a result, even if the MFP 10 and the mobile terminal 50 belong to a wireless network constructed by different access points, if the SSIDs match, it is determined that the MFP 10 and the mobile terminal 50 belong to the same wireless network. obtain.

When the mobile terminal 50 currently belongs to the network to which the MFP 10 currently belongs, the MFP 10 and the mobile terminal 50 can perform communication via the network to which the MFP 10 currently belongs. That is, the mobile terminal 50 can execute wireless communication with the MFP 10 by using the wireless settings currently stored in the work area 58. In S7, the control unit 30 transmits setting change-free information indicating that data communication can be executed without changing the wireless setting of the mobile terminal 50 via the NFCI / F22, and proceeds to S20. The setting change unnecessary information includes the IP address of the MFP 10.

In S8, the determination unit 42 determines whether or not the WFD = ON mode is set. When the mode value stored in the memory 34 is a value representing the WFD = ON mode, the determination unit 42 determines YES in S8 and proceeds to S10. On the other hand, when the mode value stored in the memory 34 is a value representing the WFD = OFF mode, the determination unit 42 determines NO in S8 and proceeds to S9.

In S9, the communication execution unit 44 changes the WFD = OFF mode to the WFD = ON mode by changing the mode value stored in the memory 34, and proceeds to S15. The communication execution unit 44 further stores the setting change information indicating that the mode value has been changed in the memory 34.

In S10, the determination unit 42 determines whether or not the MFP 10 is operating as a client state in the wireless network to which it currently belongs. Specifically, the determination unit 42 determines that the operation is operating as a client state when the state value stored in the work area 38 is a value representing the client state (YES in S10). On the other hand, if the state value stored in the work area 38 is not a value representing the client state, the determination unit 42 determines that the client state is not operating (NO in S10). If YES in S10, the process proceeds to S14.

On the other hand, when NO in S10, in S12, the determination unit 42 determines whether or not the MFP 10 is operating in the G / O state in the wireless network to which it currently belongs. Specifically, when the state value stored in the work area 38 is a value representing the G / O state, the determination unit 42 determines that the state value is operating as the G / O state (YES in S12). ). On the other hand, the determination unit 42 does not operate as a G / O state (that is, the MFP 10 is a device state) when the state value stored in the work area 38 is not a value representing the G / O state. Judge (NO in S12). If YES in S12, the process proceeds to S13, and if NO in S12, the process proceeds to S15.

In S13, in the determination unit 42, the number of devices other than the MFP 10 included in the WFD network in which the MFP 10 is operating in the G / O state (that is, the devices whose connection is established with the MFP 10) is predetermined. Determine if it is less than the maximum number of clients. The determination unit 42 determines YES in S13 when the number of device identification information stored in the management list is less than the maximum number of clients, and determines NO in S13 when they are equal. If YES in S13, the process proceeds to S16, and if NO in S13, the process proceeds to S14.

In S14, the communication execution unit 44 transmits communication NG information indicating that the MFP 10 and the mobile terminal 50 cannot currently execute communication to the mobile terminal 50 using the NFCI / F22, and performs communication processing. To finish.

In S15, the communication execution unit 44 sets the MFP 10 to the spontaneous G / O mode. The spontaneous G / O mode is a mode in which the MFP 10 is maintained to operate in the G / O state. Therefore, although the WFD network is not constructed at the stage of S15, the MFP 10 is set to the G / O state. When the MFP10 is set to the G / O state, the communication execution unit 44 wirelessly communicates with the MFP10 in which the WFD compatible device and / and the WFD non-compatible device are operating in the G / O state via the WFD network. Prepare wireless settings (SSID, BSSID, authentication method, encryption method, password, etc.) for execution. According to this configuration, the MFP 10 is a device that receives the wireless settings regardless of whether the device that receives the wireless settings from the MFP 10 (the mobile terminal 50 in this embodiment) is a WFD compatible device or a WFD non-compatible device. And wireless communication can be executed. Generally, the communication execution unit 44 is for the MFP 10 to belong to the network when it currently belongs to the network according to the first wireless communication method (or wireless communication standard or wireless communication protocol). In the wireless setting, the mobile terminal 50 has a second wireless communication system (or wireless communication standard or wireless communication) different from the first wireless communication system (or wireless communication standard or wireless communication protocol). The radio setting for operating according to the protocol) is transmitted to the communication execution unit 44.

The authentication method and the encryption method are predetermined. In addition, the communication execution unit 44 generates a password. The SSID may be generated by the communication execution unit 44 when the password is generated, or may be determined in advance. BSSID is the MAC address of the MFP10. At this stage, the management list managed by the MFP 10 does not describe the identification information of the device connected to the device in the G / O state.

In S16, the communication execution unit 44 transmits the prepared wireless setting to the mobile terminal 50 by using the NFCI / F22. When the process of S16 is executed after the process of S15, the communication execution unit 44 transmits the wireless setting prepared at the stage (S15) set in the spontaneous G / O mode to the mobile terminal 50. When the processing of S16 is executed after the processing of S13, the communication execution unit 44 sets the NFCI / F22 to the radio settings prepared at the stage when the WFD network in which the MFP10 is operating in the G / O state is constructed. It is used and transmitted to the mobile terminal 50.

Next, in S18, the communication execution unit 44 establishes a WFD connection between the MFP 10 and the mobile terminal 50 by using the wireless LANI / F20. When the mobile terminal 50 receives the wireless setting of the MFP 10 operating in the G / O state from the MFP 10, the received wireless setting is stored in the work area 58. Therefore, the mobile terminal 50 normally executes wireless communication according to Wi-Fi. Next, the communication execution unit 44 executes wireless communication of the Authentication Request, the Authentication Response, the Authentication Request, the Response Response, and the 4-way handshake with the mobile terminal 50. In the process of the above wireless communication, various authentication processes such as SSID authentication, authentication method and encryption method authentication, and password authentication are executed. If all authentications are successful, a wireless connection is established between the MFP 10 and the mobile terminal 50.

If both the MFP 10 and the mobile terminal 50 are in the device state, when the WFD connection is established between the MFP 10 and the mobile terminal 50, one of the MFP 10 and the mobile terminal 50 is G / Along with determining as O, G / O negotiation is executed to determine the other of the MFP 10 and the mobile terminal 50 as a client. However, since it is confirmed that the MFP 10 is in the G / O state at the stage when S16 is executed, the communication execution unit 44 does not execute the G / O negotiation and makes a WFD connection with the mobile terminal 50. To establish.

In the process of S18, the communication execution unit 44 acquires the MAC address of the mobile terminal 50 by using the wireless LANI / F20. When the wireless connection is established, the control unit 30 further adds the MAC address of the mobile terminal 50 to the management list. The MAC address of the mobile terminal 50 is included in the NFC information. As a result, the MFP 10 in the G / O state can execute communication of target data (print data, scan data, etc.) with the mobile terminal 50 in accordance with normal Wi-Fi. The target data includes data of a network layer that is higher than the physical layer of the OSI reference model. Therefore, the MFP 10 in the G / O state can execute wireless communication in the network layer with the mobile terminal 50 in the client state.

Next, in S20, the communication execution unit 44 executes data communication processing with the mobile terminal 50 via the wireless LANI / F20. The content of the data communication process changes depending on the content of the process execution instruction included in the NFC information. When the process execution instruction is a print instruction, the communication execution unit 44 receives the print data from the mobile terminal 50 in the data communication process. In this case, the control unit 30 causes the print execution unit 16 to execute a print process using the received print data.

On the other hand, when the processing execution instruction is a scan instruction, the control unit 30 causes the scan execution unit 18 to scan the document set in the scan execution unit 18 and generate scan data. Next, the communication execution unit 44 transmits the generated scan data to the mobile terminal 50.

Next, in S21, the communication execution unit 44 monitors that the mobile terminal 50 receives a disconnection request for disconnecting from the mobile terminal 50 by using the wireless LANI / F20. If the disconnection request is not received even after the lapse of the predetermined period (NO in S21), the process returns to S2. On the other hand, if a disconnection request is received from the mobile terminal 50 within a predetermined period after the data communication process of S20 is completed (YES in S21), the communication execution unit 44 disconnects the wireless connection with the mobile terminal 50. .. Specifically, the communication execution unit 44 deletes the MAC address of the mobile terminal 50 in the management list. Next, in S22, the communication execution unit 44 determines whether or not the setting of the wireless LANI / F20 has been changed by the process of S9. Specifically, the communication execution unit 44 determines that the mode value indicating the WFD = OFF mode has been changed to the mode value indicating the WFD = ON mode in S9 when the setting change information is stored in the memory 34. Then (YES in S22), proceed to S23. On the other hand, when the setting change information is not stored in the memory 34, the communication execution unit 44 is not changed from the mode value indicating the WFD = OFF mode to the mode value indicating the WFD = ON mode in S9 (in S22). Judging NO), the process returns to S2.

In S23, the communication execution unit 44 determines whether or not an external device (for example, PC8) other than the mobile terminal 50 currently belongs to the WFD network newly constructed in S18. Specifically, when the management list contains identification information other than the identification information of the mobile terminal 50, the communication execution unit 44 currently belongs to the WFD network (YES in S23). Judge. In this case, the mode value is not changed and the process returns to S2. According to this configuration, it is possible to prevent the MFP 10 from being detached from the WFD network when the external device currently belongs to the WFD network.

On the other hand, when the management list does not include identification information other than the mobile terminal 50, the communication execution unit 44 determines that the external device does not currently belong to the WFD network (NO in S23). Proceed to S24. In S24, the communication execution unit 44 changes from the mode value indicating the WFD = ON mode to the mode value indicating the WFD = OFF mode, and returns to S2. That is, in the communication process, when it is determined in S8 that the WFD = OFF mode, the wireless communication using the wireless LANI / F20 is temporarily executed with the mobile terminal 50 via the WFD network. , WFD = OFF mode is changed to WFD = ON mode. Then, when the WFD = ON mode is changed to the WFD = OFF mode in S25, the WFD network constructed in S18 disappears. According to this configuration, when the mode value is changed from the mode value indicating WFD = OFF mode to the mode value indicating WFD = ON mode during communication processing execution, the mode value can be returned to the setting before the change. it can.

(Effect of this example)
The effects of this embodiment in the first to fifth situations will be described with reference to FIGS. 3 to 7. In addition, each of FIGS. 3 to 7 shows a corresponding process in the communication process of FIG.

(First situation)
In the first situation shown in FIG. 3, the MFP 10 and the mobile terminal 50 currently belong to the same WFD network or the same normal Wi-Fi network. In this situation, when the NFC information is received from the mobile terminal 50 using the NFCI / F22, in S4, the MFP10 determines that the MFP10 currently belongs to the network (YES in S4). Next, in S6, the MFP 10 determines that the mobile terminal 50 currently belongs to the network to which the MFP 10 currently belongs (YES in S6). In S7, the MFP 10 transmits the setting change unnecessary information to the mobile terminal 50 by using the NFCI / F22. When the mobile terminal 50 receives the setting change unnecessary information, the mobile terminal 50 transmits the print data to the MFP 10 by using the IP address included in the setting change unnecessary information and the wireless setting stored in the work area 58. The MFP 10 receives print data using the wireless LANI / F20 (S20). Upon receiving the print data, the MFP 10 causes the print execution unit 16 to execute the print process.

In the sequence diagram of the present specification, the MFP10 uses NFCI / F22 for wireless communication (that is, wireless communication according to the NFC method), and the MFP10 uses wireless LANI / F20 for wireless communication (that is, WFD method or normal Wi). -Wireless communication according to Fi) is indicated by an arrow. The arrow indicating wireless communication using wireless LANI / F20 is drawn thicker than the arrow indicating wireless communication using NFCI / F22.

According to this configuration, the MFP 10 can change the wireless settings currently set for the MFP 10 and the mobile terminal 50 when it is determined that the mobile terminal 50 currently belongs to the network to which the MFP 10 currently belongs. Instead, the MFP 10 and the mobile terminal 50 can appropriately communicate print data via the network to which they currently belong.

(Second situation)
In the second situation shown in FIG. 4, the MFP10 currently belongs to the WFD network. The MFP 10 is operating in the G / O state in the WFD network. The client-state PC8 currently belongs to the WFD network. The mobile terminal 50 does not currently belong to the wireless network to which the MFP 10 currently belongs. The mobile terminal 50 may or may not currently belong to a wireless network other than the wireless network to which the MFP 10 currently belongs.

In this situation, when the NFC information is received from the mobile terminal 50 using the NFCI / F22, the MFP10 determines in S4 that the MFP10 currently belongs to the network (YES in S4). The NFC information includes the SSID and BSSID of the wireless network when the mobile terminal 50 currently belongs to the wireless network, but the NFC information of the wireless network when the mobile terminal 50 does not currently belong to the wireless network. Does not include SSID and BSSID. Next, in S6, the MFP 10 determines that the mobile terminal 50 does not currently belong to the WFD network to which the MFP 10 currently belongs (YES in S6). The MFP10 determines in S12 that the MFP10 is in the G / O state (YES in S12). In this case, in S16, the MFP 10 transmits the wireless setting of the MFP 10 stored in the work area 38 and the IP address of the MFP 10 to the mobile terminal 50 by using the NFCI / F22. When the mobile terminal 50 receives the wireless setting, the mobile terminal 50 stores the received wireless setting in the work area 58. Next, the MFP 10 and the mobile terminal 50 establish a WFD connection (S18). As a result, the mobile terminal 50 can belong to the WFD network to which the MFP 10 currently belongs. The MFP 10 transmits the wireless settings including the authentication method and the encryption method of the MFP 10 to the mobile terminal 50 by using the NFCI / F22. According to this configuration, the mobile terminal 50 can execute the authentication process according to the authentication method and the encryption method received from the MFP 10, and executes the process of confirming which authentication method and encryption method should be used. You don't have to. Therefore, the connection between the MFP 10 and the mobile terminal 50 can be established relatively early.

Next, the mobile terminal 50 transmits the print data to the MFP 10 by using the wireless setting stored in the work area 58 and the IP address received in S16. The MFP 10 receives print data using the wireless LANI / F20 (S20). Upon receiving the print data, the MFP 10 causes the print execution unit 16 to execute the print process. According to this configuration, when the MFP 10 is operating in the G / O state in the WFD network, the MFP 10 communicates print data with the mobile terminal 50 via the WFD network to which the MFP 10 currently belongs. Can be done properly.

(Third situation)
In the third situation shown in FIG. 5, the MFP10 currently belongs to the WFD network. The MFP 10 is operating as a client state in the WFD network. The PC8 in the G / O state currently belongs to the WFD network, but the mobile terminal 50 does not currently belong to it. The mobile terminal 50 is the same as in the second situation.

In this situation, when the NFC information is received from the mobile terminal 50 using the NFCI / F22, in S4, the MFP10 determines that the MFP10 currently belongs to the network (YES in S4). Next, in S6, the MFP 10 determines that the mobile terminal 50 does not currently belong to the WFD network to which the MFP 10 currently belongs (NO in S6). The MFP10 determines in S10 that the MFP10 is in the client state (YES in S10). In this case, in S14, the MFP 10 transmits the communication NG information to the mobile terminal 50 by using the NFCI / F22.

In this case, the MFP 10 does not transmit the wireless setting stored in the work area 38 to the mobile terminal 50. According to this configuration, it is not necessary to provide the mobile terminal 50 with the wireless setting of the PC 8 operating in the G / O state in the WFD network. As a result, it is possible to prevent the mobile terminal 50 from entering the WFD network. Further, the mobile terminal 50 can notify the user of the mobile terminal 50 that the MFP 10 does not execute the communication of the target data with the mobile terminal 50 by receiving the communication NG information from the MFP 10.

(Fourth situation)
In the fourth situation shown in FIG. 6, the MFP10 has the wireless LANI / F20 set to WFD = ON mode, but does not currently belong to the WFD network. That is, the MFP 10 is operating as a device state. The MFP10 is usually not currently affiliated with the Wi-Fi network. The mobile terminal 50 is the same as in the second situation.

In this situation, when the NFC information is received from the mobile terminal 50 using the NFCI / F22, in S4, the MFP10 determines that the MFP10 does not currently belong to the network (NO in S4). Further, the MFP10 determines in S10 and S12 that the MFP10 is neither in the G / O state nor in the client state (NO in both S10 and S12). In this case, in S15, the MFP 10 sets the MFP 10 to the spontaneous G / O mode without executing the G / O negotiation.

Next, in S16, the MFP 10 uses the wireless setting of the MFP 10 stored in the work area 38 (that is, the wireless setting generated at the stage of being set to the spontaneous G / O mode in S15) and the IP address of the MFP 10. To the mobile terminal 50 using NFCI / F22. When the mobile terminal 50 receives the wireless setting, the mobile terminal 50 stores the received wireless setting in the work area 58. Next, the MFP 10 and the mobile terminal 50 establish a WFD connection (S18). As a result, the mobile terminal 50 can belong to the WFD network in which the MFP 10 is operating in the G / O state.

Next, the mobile terminal 50 transmits the print data to the MFP 10 by using the wireless setting stored in the work area 58 and the IP address received in S16. The MFP 10 receives print data using the wireless LANI / F20 (S20). Upon receiving the print data, the MFP 10 causes the print execution unit 16 to execute the print process. According to this configuration, the MFP 10 can newly construct a WFD network in which the MFP 10 operates as a G / O state in the WFD network. As a result, the MFP 10 can appropriately communicate the print data with the mobile terminal 50 via the newly constructed WFD network. Further, since the MFP 10 inevitably operates in the G / O state in the newly constructed WFD network, the authentication method or the like used in the WFD network can be determined.

(Fifth situation)
In the fifth situation shown in FIG. 7, the MFP10 has the wireless LANI / F20 set to the WFD = OFF mode. MFP10 is in a state that does not currently belong to the network. The mobile terminal 50 is the same as in the second situation.

In this situation, when the NFC information is received from the mobile terminal 50 using the NFCI / F22, it is determined as NO in S4 as in the fourth situation. The MFP10 determines in S8 that the WFD = OFF mode is set. In this case, in S9, the MFP 10 changes from the WFD = OFF mode to the WFD = ON mode. Next, the MFP 10 sets the MFP 10 to the spontaneous G / O mode in S15.

Hereinafter, the process up to the printing process is the same as in the fourth situation. Even in this configuration, the same effect as in the fourth situation can be obtained. When the printing process is completed, the MFP 10 determines that the external device does not currently belong to the newly constructed WFD network (NO in S23), and changes the WFD = ON mode to the WFD = OFF mode. According to this configuration, when the external device does not belong to the WFD network after the communication of the print data, the WFD = ON mode can be appropriately changed to the WFD = OFF mode.

In this embodiment, the MFP 10 executes a process according to whether or not the MFP 10 currently belongs to the same network as the mobile terminal 50, that is, whether or not the MFP 10 can communicate with the mobile terminal 50. Thereby, the wireless LANI / F20 can be used to appropriately perform wireless communication between the mobile terminal 50 and the target data at a relatively high communication speed. Further, the MFP 10 can execute the communication of the target data via the WFD network without the mobile terminal 50 and the access point different from the MFP 10 and the mobile terminal 50.

Further, when the MFP10 cannot communicate with the mobile terminal 50 and the MFP10 currently belongs to the WFD network, the MFP10 can use the mobile terminal 50 and the target data via the WFD network to which the MFP10 currently belongs. Communication can be executed properly. Further, when the MFP 10 does not currently belong to the WFD network, the MFP 10 can appropriately perform communication of target data with the mobile terminal 50 via the newly constructed WFD network.

From the above description, the NFCI / F22 (that is, the "type 1 interface") uses the MFP10 (that is, the "type 1 interface") to execute communication using the wireless LANI / F20 (that is, the "type 2 interface"). It can be said that it is an interface used for communication executed between the "communication device") and the mobile terminal 50.

The case of YES in S4 of FIG. 2 is an example of the "first case", and the case of NO in S4 of FIG. 2 is an example of the "second case".

(Second Example)
The points different from the first embodiment will be described. In this embodiment, the mobile terminal 50 further includes a password, an authentication method, and an encryption method as wireless settings stored in the work area 58 when the mobile terminal 50 currently belongs to the network. Is transmitted to the MFP 10.

Further, in this embodiment, the communication process of FIG. 8 is executed instead of the communication process of FIG. S2 to S24 in FIG. 8 are the same as the processes in S2 to S24 in FIG. In the case of NO in S4 (that is, when the MFP 10 does not currently belong to the network), in S82, the determination unit 42 includes the wireless setting in the NFC information received from the mobile terminal 52 via the NFC interface 22. Judge whether or not it is. When it is determined that the wireless setting is included (YES in S82), in S83, the setting change unnecessary information is transmitted to the mobile terminal 50 using NFCI / F22. When NO in S4 (that is, when the MFP 10 does not currently belong to the network), in S83, the setting change unnecessary information including the MAC address of the MFP 10 is transmitted to the mobile terminal 50. On the other hand, if YES in S4 and NO in S6 (that is, the MFP10 currently belongs to the network, but the MFP10 and the mobile terminal 50 do not currently belong to the same network), in S83, the MFP10 The setting change unnecessary information including the IP address is transmitted to the mobile terminal 50. Next, in S84, the communication execution unit 44 belongs to the network to which the mobile terminal 50 belongs by using the wireless setting included in the NFC information, and proceeds to S20.

On the other hand, if it is determined that the NFC information does not include the wireless setting (NO in S82), the process proceeds to S8.

(Effect of this example)
The MFP 10 of the second embodiment can exert the same effect as the MFP 10 of the first embodiment in the situations 1 to 5. The effect of this embodiment in the sixth situation will be described with reference to FIG. Note that FIG. 9 shows the corresponding processing in the communication processing of FIG.

(Sixth situation)
In the sixth situation shown in FIG. 9, the MFP 10 is not currently affiliated with the network. On the other hand, the mobile terminal 50 currently belongs to the normal Wi-Fi network to which the AP6 belongs.

In this situation, when the NFC information is received from the mobile terminal 50 via the NFCI / F22, the MFP10 determines that the MFP10 currently belongs to the network (YES in S4). Next, in S82 of FIG. 8, the MFP 10 determines that the wireless setting for belonging to the network to which the mobile terminal 50 currently belongs is included in the NFC information (YES in S82).

Next, in S83, the MFP 10 transmits the setting change unnecessary information to the mobile terminal 50 using the NFCI / F22. If the MFP 10 is NO in S4 (that is, the MFP 10 does not currently belong to the network), the MFP 10 transmits the setting change unnecessary information including the MAC address of the MFP 10 to the mobile terminal 50. Further, when the MFP10 is NO in S6 (that is, when the MFP10 currently belongs to the network, but the MFP10 and the mobile terminal 50 do not belong to the same network), the setting change unnecessary information including the IP address of the MFP10 is input. It is transmitted to the mobile terminal 50.

The MFP10 establishes a normal Wi-Fi connection with the AP6 using the wireless settings included in the NFC information (S84). When the setting change unnecessary information includes the IP address of the MFP 10, the mobile terminal 50 designates the IP address as the transmission destination and transmits the print data to the MFP 10 via the AP6 (S20). Further, when the setting change unnecessary information includes the MAC address of the MFP10, the mobile terminal 50 specifies the IP address of the MFP10 according to RARP (abbreviation of Reverse Address Resolution Protocol) and specifies the specified IP address as the transmission destination. Then, the print data is transmitted to the MFP 10 via the AP6 (S20).

According to this configuration, when the MFP 10 and the mobile terminal 50 do not belong to the same network, the MFP 10 appropriately communicates print data with the mobile terminal 50 via the network to which the mobile terminal 50 currently belongs. Can be executed.

(Correspondence)
The network to which the mobile terminal 50 belongs is an example of the “second target network”. The case of YES in S4 of FIG. 8 is an example of the "first case", the case of NO in S4 of FIG. 8 is an example of the "second case", and the case of NO in S4 of FIG. And, the case of YES in S82 is an example of "specific case".

(Third Example)
The points different from the first embodiment will be described. In this embodiment, the communication process of FIG. 10 is executed instead of the communication process of FIG. S2 to S12 and S15 to S24 in FIG. 10 are the same as the processes in S2 to S12 and S15 to S24 in FIG. If NO in S8, that is, if the MFP 10 is not set to WFD = ON mode, in S76, the determination unit 42 determines whether the MFP 10 currently belongs to the normal Wi-Fi network. When the information indicating that the information indicating that the device currently belongs to the normal Wi-Fi network is stored in the work area 38, the determination unit 42 determines that the MFP 10 currently belongs to the normal Wi-Fi network (YES in S76). Then proceed to S80. On the other hand, the determination unit 42 determines that the MFP 10 does not currently belong to the normal Wi-Fi network (NO in S76) when the information indicating that it belongs to the normal Wi-Fi network is not stored in the work area 38. Judge and proceed to S9.

If YES in S12, that is, if the MFP10 currently belongs to the WFD network and is operating in the G / O state in the WFD network, the process proceeds to S13. In S16, the communication execution unit 44 transmits the wireless setting of the MFP 10 stored in the work area 38 to the mobile terminal 50 via the NFCI / F22, and proceeds to S18. The wireless setting of the MFP 10 transmitted in S16 includes a password.

Further, when NO is determined in S12, that is, when the MFP 10 is operating as a device state, the determination unit 42 executes the process of S78. The process of S78 is the same as the process of S76. If NO in S78, the process proceeds to S15, and if YES in S78, the process proceeds to S80.

In S80, the communication execution unit 44 sets the wireless settings for belonging to the normal Wi-Fi network stored in the work area 38, that is, the wireless settings other than the password among the wireless settings of the AP (for example, AP6) to the NFC. It transmits to the mobile terminal 50 via the interface 22 and proceeds to S20. When the mobile terminal 50 receives the wireless setting of the AP, the mobile terminal 50 causes the user to specify the password. When the password is specified by the user, the mobile terminal 50 establishes a connection with the AP by using the wireless setting received from the MFP 10 and the password specified by the user. As a result, the mobile terminal 50 can wirelessly communicate with the MFP 10 via the AP. If the connection between the mobile terminal 50 and the AP is not established, the MFP 10 cannot execute wireless communication with the mobile terminal 50. In this case, the control unit 30 returns to S2 without executing the processes of S20 to S24.

(Effect of this example)
The MFP 10 of the third embodiment can exert the same effect as the MFP 10 of the first embodiment in the situations 1 to 5. The effect of this embodiment in the seventh situation will be described with reference to FIG. Note that FIG. 11 shows the corresponding processing in the communication processing of FIG.

(7th situation)
In the seventh situation shown in FIG. 11, the MFP10 currently belongs to a Wi-Fi network, usually. The MFP10 is usually connected to the AP6 in a Wi-Fi network. The mobile terminal 50 is the same as in the second situation.

In this situation, when the NFC information is received from the mobile terminal 50 using the NFCI / F22, in S4, the MFP10 determines that the MFP10 currently belongs to the network (that is, the normal Wi-Fi network). (YES in S4). Next, in S6, the MFP 10 determines that the mobile terminal 50 does not currently belong to the normal Wi-Fi network to which the MFP 10 currently belongs (NO in S6). In S76, the MFP10 determines that it currently belongs to the Wi-Fi network (YES in S76). In this case, in S80, the MFP 10 transmits the wireless setting of the AP6 stored in the work area 38, the wireless setting not including the password, and the IP address of the MFP 10 to the mobile terminal 50. According to this configuration, it is not necessary to provide the password to the mobile terminal 50 and the user. As a result, when the mobile terminal 50 and the user do not know the password for belonging to the normal Wi-Fi network in which AP6 is used, it is possible to prevent the mobile terminal 50 from belonging to the normal Wi-Fi network. it can.

When the mobile terminal 50 receives the wireless setting, the mobile terminal 50 receives the wireless setting and causes the user to specify the password, as in the tenth situation. The mobile terminal 50 then establishes a normal Wi-Fi connection with the AP6 when the password is specified by the user. As a result, the mobile terminal 50 can belong to the normal Wi-Fi network to which the MFP 10 currently belongs. The mobile terminal 50 can transmit print data to the MFP 10 via the AP6. When the mobile terminal 50 normally belongs to the Wi-Fi network, the mobile terminal 50 executes wireless communication via the AP6 by using the wireless settings stored in the work area 58 and the IP address of the MFP 10 received in S80. , The print data is transmitted to the MFP 10.

Although not shown, even when the MFP10 is currently operating as a device state (Yes in S8, NO in S10 and S12) and the MFP10 normally belongs to the Wi-Fi network (YES in S78). The MFP 10 transmits the wireless setting of the AP stored in the work area 38, which does not include the password, to the mobile terminal 50.

According to this configuration, when the MFP 10 does not belong to the same network as the mobile terminal 50, the MFP 10 appropriately communicates print data with the mobile terminal 50 via the normal Wi-Fi network to which the MFP 10 currently belongs. Can be executed.

(Correspondence)
When YES is determined in S4 of FIG. 10, the non-WFD network to which the MFP 10 belongs is an example of the “first target network”. The case of YES in S4 of FIG. 10 is an example of the "first case", and the case of NO in S4 of FIG. 10 is an example of the "second case".

Although specific examples of the present invention have been described in detail above, these are merely examples and do not limit the scope of claims. The techniques described in the claims include various modifications and modifications of the specific examples illustrated above. Modifications of the above embodiment are listed below.

(Modification example)
(1) In the first to third embodiments described above, when the MFP10 receives the NFC information (YES in S2), it determines whether it currently belongs to the network (S4), and it is determined that it belongs to the network. In this case (YES in S4), it is determined whether the MFP 10 and the mobile terminal 50 currently belong to the same network (S6). However, the processing of S6 may be omitted. That is, in the first and third embodiments, when the MFP10 receives the NFC information (YES in S2), it determines whether it currently belongs to the network (S4), and when it is determined that it currently belongs to the network. (YES in S4), the process may proceed to S8 and subsequent processes. Further, in the second embodiment, when it is determined that the MFP 10 currently belongs to the network (YES in S4), the MFP 10 may proceed to the processing after S82.

(2) The "communication device" is not limited to a multifunctional device, but is another device (for example, a printer, a fax device, a copier, a scanner, etc.) having a first-class interface and a second-class interface. May be good.

(3) The MFP 10 may store an AP program for functioning as an access point. When the control unit 30 activates the AP program, the control unit 30 may store a predetermined wireless setting in the work area 38. In S4 of FIG. 2, the determination unit 42 may determine that the MFP 10 is currently participating in the network (non-WFD network) when the AP program is activated. In this modification, the normal Wi-Fi network constructed in a state where the MFP 10 is functioning as an access point is an example of the “first target network”.

(4) Further, for example, in S15 of FIG. 2, the communication execution unit 44 may start the AP program instead of setting the MFP 10 to the spontaneous G / O mode. Next, the communication execution unit 44 may transmit the wireless setting stored in the work area 38 to the mobile terminal 50. Then, the communication execution unit 44 and the mobile terminal 50 may establish a connection by using the wireless settings stored in advance in the work area 38. In this case, the MFP 10 may establish a normal Wi-Fi connection with the mobile terminal 50, and the MFP 10 may build a normal Wi-Fi network. In this modification, the normal Wi-Fi network constructed in a state where the MFP 10 is functioning as an access point is an example of the “second target network”.

(5) The combination of the "type 1 interface" and the "type 2 interface" is not limited to the combination of the NFCI / F and the wireless LANI / F. For example, when a wireless LAN I / F is adopted as the "second type interface", the "first type interface" may be an interface for executing infrared communication, or may be an interface for executing infrared communication, or Bluetooth®. It may be an interface for executing TransferJet, or it may be an interface for executing TransferJet. Further, when NFCI / F is adopted as the "first-class interface", the "second-class interface" may be an interface for executing wired communication, or Bluetooth (registered trademark) may be used. It may be an interface for execution. Generally speaking, the communication speed of communication via the first-class interface may be faster than the communication speed of communication via the first-class interface.

(6) The "type 1 interface" and the "type 2 interface" may be physically two interfaces (that is, two separate chips) as in the above embodiment. Alternatively, it may be physically one interface (that is, one chip realizes two types of communication).

(7) In each of the above embodiments, there is physically one interface for executing wireless communication according to the WFD method and an interface for executing wireless communication according to normal Wi-Fi. Interface (wireless LANI / F20), but may be physically a plurality of interfaces (that is, two separate IC chips). In this modification, the plurality of interfaces is an example of the "second type interface".

(8) In each of the above embodiments, in S15, the communication execution unit 44 sets the MFP 10 to the spontaneous G / O mode. However, when the mobile terminal 50 can execute wireless communication according to the WFD, the communication execution unit 44 sends the WFD connection start information indicating that the WFD connection is started to the mobile terminal via the NFC interface 22. It may be transmitted to 50. As a method for executing the wireless connection of WFD, a wireless connection method of WPS (abbreviation of Wi-Fi Protected Setup) may be used. The WPS wireless connection method includes a PBC (abbreviation of Push Button Configuration) method and a PIN (abbreviation of Personal Identification Number) code method. In this modification, the PBC code method will be described, but the technique of this modification can also be applied to the PIN code method. The WFD connection start information may include information indicating that the PBC code method is used as the method for executing the wireless connection of the WFD method. The WFD connection start information may further include the device ID (for example, MAC address, serial number, etc.) of the MFP 10.

When the WFD connection start information is received, the mobile terminal 50 may determine whether or not the wireless LAN I / F setting of the mobile terminal 50 is a setting capable of executing wireless communication according to the WFD method. .. When the wireless LANI / F setting is a setting capable of executing wireless communication according to the WFD method, the mobile terminal 50 maintains the wireless LANI / F setting, and the wireless LANI / F setting is changed to the WFD method. If the setting is not such that the wireless communication according to the method can be executed, the setting of the wireless LAN I / F may be changed to a setting that enables the wireless communication according to the WFD method.

Next, the communication execution unit 44 may search the mobile terminal 50. Specifically, the communication execution unit 44 may sequentially execute the Scan process, the Listen process, and the Search process. The Scan process is a process for searching for devices in the G / O state existing around the MFP 10. Specifically, the communication execution unit 44 may sequentially use 13 channels of 1ch to 13ch in the Scan process to sequentially transmit the Probe Request signal wirelessly. The Probe Request signal may include P2P (Peer 2 Peer) information indicating that the MFP 10 can execute the WFD function.

For example, when there is a WFD compatible device in the G / O state (hereinafter referred to as "specific G / O device") around the MFP 10, the specific G / O device is one of 1ch to 13ch. It may be decided in advance to use the individual channels. Therefore, a particular G / O device may wirelessly receive a Probe Request signal from the MFP 10. In this case, the specific G / O device may wirelessly transmit the Probe Response signal to the MFP 10. This Probe Response signal includes P2P information indicating that the specific G / O device can execute the WFD function, and information indicating that the specific G / O device is in the G / O state. May be good. As a result, the communication execution unit 44 can find a specific G / O device. In addition, the above-mentioned Probe Response signal further includes a device name of a specific G / O device, information indicating a model of the specific G / O device (for example, a mobile terminal, a PC, etc.), and a specific G / O device. MAC address and may be included. As a result, the communication execution unit 44 can acquire information about a specific G / O device.

When the device ID (for example, MAC address, serial number, etc.) of a specific G / O device included in the Probe Response signal and the device ID of the mobile terminal 50 included in the NFC information match, the communication execution unit 44 determines. It is possible to specify that the specific G / O device is the mobile terminal 50. That is, when the mobile terminal 50 currently belongs to the WFD network and is operating in the G / O state in the WFD network, the communication execution unit 44 may discover the mobile terminal 50 by Scan processing. it can.

For example, when there is a WFD compatible device in a device state (hereinafter referred to as "specific device device") around the MFP 10, the specific device device is one of 1ch, 6ch, and 11ch. It may be decided in advance to use the channel. Therefore, the specific device may also receive the Probe Request signal wirelessly from the MFP 10. In this case, the specific device device may wirelessly transmit the Probe Response signal to the MFP 10. However, this Probe Response signal may include information indicating that the device is in the device state, and may not include information indicating that the device is in the G / O state. Further, the device in the client state may receive the Probe Request signal wirelessly from the MFP 10 or may not transmit the Probe Response signal wirelessly to the MFP 10. The communication execution unit 44 can discover the mobile terminal 50 in the Scan process regardless of whether the mobile terminal 50 is in the G / O state or the device state.

The Listen process is a process for responding to a Probe Request signal. A specific device device can wirelessly transmit a probe request signal in the search process described later. That is, when the current state of the mobile terminal 50 is the device state, the mobile terminal 50 may wirelessly transmit the Probe Request signal periodically. This Probe Request signal may include the device ID (for example, MAC address, serial number, etc.) of the mobile terminal 50.

When the device ID of the specific device device included in the Probe Request signal and the device ID of the mobile terminal 50 included in the NFC information match, the communication execution unit 44 means that the specific device device is the mobile terminal 50. Can be identified. That is, when the mobile terminal 50 is operating as a device state, the communication execution unit 44 can discover the mobile terminal 50 by the Listen process. When the communication execution unit 44 receives the Probe Request signal from the mobile terminal 50, the communication execution unit 44 may wirelessly transmit the Probe Response signal.

In the search process, the communication execution unit 44 may sequentially use the three channels of 1ch, 6ch, and 11ch to sequentially transmit the probe request signal wirelessly. As a result, the communication execution unit 44 may wirelessly receive the Probe Response signal from the specific device device. This Probe Response signal includes P2P information indicating that a specific device device can execute the WFD function, information indicating that the specific device device is in the device state, and a device ID (for example, MAC) of the specific device device. Address, serial number, etc.) and may be included. When the current state of the mobile terminal 50 is the device state, the mobile terminal 50 may wirelessly transmit a Probe Response signal in response to the Probe Request signal transmitted from the MFP 10.

When the device ID of the specific device device included in the Probe Response signal and the device ID of the mobile terminal 50 included in the NFC information match, the communication execution unit 44 means that the specific device device is the mobile terminal 50. Can be identified. That is, when the mobile terminal 50 currently belongs to the WFD network and is operating as a device state in the WFD network, the communication execution unit 44 can discover the mobile terminal 50 by the search process.

When the mobile terminal 50 is found, the MFP 10 uses the wireless LANI / F20 to execute G / O negotiation with the mobile terminal 50 to G the device of either the MFP 10 or the mobile terminal 50. You may decide to operate in the / O state and decide to operate the other device in the client state.

Next, the communication execution unit 44 may establish a connection between the MFP 10 and the mobile terminal 50 according to WPS. Specifically, the communication execution unit 44 communicates when the current state of the MFP 10 is the G / O state and the current state of the mobile terminal 50 is the client state (YES in S22). The execution unit 44 may generate wireless settings (SSID, authentication method, encryption method, password, etc.) necessary for establishing a wireless connection and wirelessly transmit them to the mobile terminal 50. The authentication method and the encryption method may be predetermined. Further, the communication execution unit 44 may generate a password when generating the wireless setting. The SSID may be generated by the communication execution unit 44 or may be predetermined. By transmitting the wireless setting to the mobile terminal 50, the MFP 10 and the mobile terminal 50 can use the same wireless setting. That is, the MFP 10 and the mobile terminal 50 may execute the wireless communication of the Authentication Request, the Authentication Response, the Authentication Request, the Authentication Response, and the 4-way handshake by using the wireless settings. In this process, the MFP 10 and the mobile terminal 50 may perform various authentication processes such as SSID authentication, authentication method and encryption method authentication, and password authentication. If all the authentications are successful, a wireless connection may be established between the MFP 10 and the mobile terminal 50. As a result, the MFP 10 and the mobile terminal 50 may be in a state of belonging to the same WFD network.

On the other hand, when the current state of the MFP 10 is the client state and the current state of the target device is the G / O state, the communication execution unit 44 may execute the WPS negotiation for the client state. Good. Specifically, the mobile terminal 50 may generate wireless settings (SSID, authentication method, encryption method, password, etc.) necessary for establishing a wireless connection and transmit them wirelessly to the MFP 10. As a result, the communication execution unit 44 may wirelessly receive the wireless setting from the mobile terminal 50. Subsequent processing (communication processing such as Authentication Request) is the same as WPS negotiation for the G / O state. As a result, the MFP 10 and the mobile terminal 50 may be in a state of belonging to the same WFD network. As a result, the MFP 10 in the client state can execute wireless communication of target data (print data, etc.) with the mobile terminal 50 in the G / O state. In this modification, G / O negotiation and WPS negotiation are examples of "specific processing".
