In one technique disclosed by this specification, the device-side control unit of the communication device may include a specific data reception unit, a determination unit, an information transmission unit, and a device-side communication execution unit. The specific data receiving unit receives specific data from the mobile terminal via the first type interface. The specific data includes identification information for identifying the wireless network to which the mobile terminal belongs. The determination unit uses the identification information to determine whether the mobile terminal belongs to the fifth wireless network when the specific data is received and the communication device belongs to the fifth wireless network. to decide. A fifth wireless network is a wireless network in which a communication device operates as a slave station and performs wireless communication via a second type interface. The information transmitting unit transmits fifth information for the mobile terminal to perform wireless communication using the fifth wireless network in a third case where the mobile terminal is determined to belong to the fifth wireless network. and sixth information for the mobile terminal to perform wireless communication using the sixth wireless network to the mobile terminal via the first type interface, and the mobile terminal transmits the fifth wireless network In the fourth case where it is determined not to belong to the network, without transmitting the fifth information, the sixth information is transmitted to the portable terminal via the first type interface.

According to the above configuration, the communication device combines the fifth information and the sixth information in the third case where it is determined that the mobile terminal belongs to the fifth wireless network in which the communication device operates as a slave station. to the mobile device. For this reason, the communication device and the mobile terminal can appropriately communicate the target data using the fifth wireless network or the sixth wireless network. Even if the communication device and the mobile terminal cannot execute the communication of the target data using the fifth wireless network, the communication device and the mobile terminal can be connected to the sixth wireless network in which the communication device operates as a master station. Communication of the subject data may suitably be performed using a wireless network. Further, in the fourth case where it is determined that the mobile terminal does not belong to the fifth wireless network in which the communication device operates as a slave station, the communication device transmits the sixth information without transmitting the fifth information. to the mobile device. For this reason, the communication device and the mobile terminal can appropriately communicate the target data using the sixth wireless network. Moreover, it is possible to prevent the security of the fifth wireless network from deteriorating.

One technology disclosed by this specification is a mobile terminal for performing communication of target data with a communication device.

(First embodiment)
(Configuration of communication system 2)
As shown in FIG. 1, a communication system 2 includes a plurality of access points (hereafter referred to as "APs (abbreviation of Access Point)") 4a and 4b and personal computers (hereafter referred to as "PCs (abbreviation of Personal Computer)"). )”) 6 and a multi-function device (hereinafter referred to as “MFP (Multi-F
(abbreviation of function peripheral) 10 and a portable terminal 50 .

(Types of wireless communication executable by MFP 10)
The MFP 10 executes wireless communication according to the NFC (Near Field Communication) system, wireless communication according to the WFD (Wi-Fi Direct) system, and wireless communication according to the normal Wi-Fi system. It is possible. Hereinafter, wireless communication according to each of the above methods will be referred to as "NFC communication", "WFD communication", and "normal Wi-Fi communication", respectively.

(NFC communication)
The NFC system is a wireless communication system for so-called short-range wireless communication, and is a wireless communication system based on the international standards of ISO/IEC21481 or 18092, for example. The MFP 10 can perform NFC communication with the mobile terminal 50 .

(WFD communication)
The WFD method is based on the standard document "Wi-Fi
Peer-to-Peer (P2P) Technical Specification Version 1.1”. The WFD system is, for example, wireless in accordance with the IEEE (abbreviation of The Institute of Electrical and Electronics Engineers, Inc.) 802.11 standard and its equivalent standards (eg, 802.11a, 11b, 11g, 11n, etc.). It is a wireless communication method for performing communication.

By belonging to the WFD network, the MFP 10 can perform WFD communication of target data with other devices belonging to the WFD network. The target data is data including network layer information of the OSI reference model, and includes, for example, print data, scan data, and the like. Also, the mobile terminal 50 and the PC 6 can perform WFD communication of target data by belonging to the WFD network.

Devices capable of executing WFD communication, such as the MFP 10 and the mobile terminal 50, are hereinafter referred to as “WFD compatible devices”. In the WFD standard described above, three states are defined as the states of a WFD-compatible device: a Group Owner state (hereinafter referred to as a "G/O state"), a client state, and a device state. A WFD-enabled device can selectively operate in one of the three states described above.

When a pair of WFD compatible devices in device state are to form a WFD network, wireless communication called G/O negotiation is normally performed between the pair of WFD compatible devices. In the G/O negotiation, it is determined that one of the pair of WFD compatible devices will be in the G/O state and the other of the pair of WFD compatible devices will be in the client state. A WFD network is formed by a device in G/O state (hereinafter referred to as "G/O device") and a device in client state (hereinafter referred to as "CL device"). A WFD network can have one G/O device and one or more CL devices. A G/O device manages one or more CL devices. Specifically, the G/O device authenticates each of one or more CL devices, and when the CL device is successfully authenticated, the identification information (that is, the MAC address) of the CL device is ) in the management list in the memory of the G/O device. When the CL device leaves the WFD network, the G/O device deletes the identification information of the CL device from the management list.

The G/O device can directly perform wireless communication of the target data with the CL device registered in the management list without going through the relay device. However, the G/O device can execute wireless communication of participation data with an unregistered device that is not registered in the management list so that the unregistered device participates in the WFD network. Wireless communication is not feasible. Participation data is data that does not include network layer information of the OSI reference model, and includes, for example, a Probe Request signal (hereinafter referred to as a "PReq signal"), a Probe Response signal (hereinafter referred to as a "PRes signal"), and the like. Contains physical layer data. Note that the G/O device can relay wireless communication of target data between a plurality of CL devices.

A WFD compatible device that does not belong to a WFD network (that is, an unregistered device that is not registered in the G/O device management list) is a device state device. A device in the device state can perform wireless communication of the participation data with the G/O device for belonging to the WFD network, but performs wireless communication of the target data with the G/O device or the CL device. Impossible.

As described above, in a WFD network, a pair of WFD-compatible devices can perform WFD communication of target data without going through an AP configured separately from these WFD-compatible devices. That is, it can be said that WFD communication is wireless communication that does not involve an AP.

In the following description, it is not possible to selectively operate in one of the three states (that is, G/O state, client state, and device state) defined in the above WFD standard, A device capable of performing wireless communication via an AP (that is, normal Wi-Fi communication to be described later) is called a “WFD non-compliant device”. A “non-WFD device” is also called a “legacy device”. A device in the G/O state can describe the identification information of the WFD-incompatible device in the management list. In this case, the WFD-incompatible device can participate in the WFD network as a CL device.

(Normal Wi-Fi communication)
The normal Wi-Fi system is a wireless communication system defined by the Wi-Fi Alliance, and is a wireless communication system different from the WFD system. As with the WFD system, the normal Wi-Fi system is a wireless communication system for executing wireless communication in accordance with the IEEE 802.11 standard and its equivalent standards (eg, 802.11a, 11b, 11g, 11n, etc.). Communication method. However, as described above, the WFD system is a wireless communication system for performing wireless communication without using an AP. On the other hand, the normal Wi-Fi system is a wireless communication system for executing wireless communication via an AP. In this respect, the WFD system differs from the normal Wi-Fi system.

By belonging to a normal Wi-Fi network, the MFP 10 can perform normal Wi-Fi communication of target data with other devices belonging to the normal Wi-Fi network via the AP. The mobile terminal 50 can also perform normal Wi-Fi communication of target data by belonging to the normal Wi-Fi network. Therefore, the MFP 10 can perform normal Wi-Fi communication of target data with the portable terminal 50 via one of the plurality of APs 4a and 4b.

A Wi-Fi network is usually a wireless network constructed in an environment in which an AP can be installed, such as an in-house LAN or a home LAN. . On the other hand, a WFD network is a wireless network that does not require an AP, for example, is a wireless network that is built to perform temporary wireless communication between a pair of WFD-compatible devices. A wireless network to be temporarily formed. Thus, in this embodiment, it is assumed that the normal Wi-Fi network is a wireless network that should be established on a regular basis, and the WFD network is a wireless network that should be temporarily established. Note that the WFD network and normal Wi-Fi network are hereinafter referred to as “WFDNW” and “normal Wi-Fi NW”.

(Configuration of MFP 10)
MFP 10 is capable of performing multiple functions, including printing and scanning functions. As shown in FIG. 1, 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/F 22 , and a control unit 30 . Each unit 12 to 30 is connected to a bus line (reference numerals omitted).

The operation unit 12 has a plurality of keys. A 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. A scan executing unit 18 is a scanning mechanism such as a CCD or a CIS.

The wireless LAN I/F 20 is an interface for executing WFD communication and normal Wi-Fi communication. The wireless LAN I/F 20 is physically one interface (that is, one IC chip). However, in the wireless LAN I/F 20, the MAC address used for WFD communication (hereinafter referred to as "WFD MAC address") and the MAC address used for normal Wi-Fi communication (hereinafter referred to as "normal Wi-Fi (referred to as a "MAC address for Specifically, the wireless LAN I/F 20 is pre-assigned a normal Wi-Fi MAC address. The control unit 30 uses the normal Wi-Fi MAC address to generate a WFD MAC address different from the normal Wi-Fi MAC address, and assigns the WFD MAC address to the wireless LAN I/F 20 . Therefore, the control unit 30 can simultaneously perform both normal Wi-Fi communication using the normal Wi-Fi MAC address and WFD communication using the WFD MAC address. That is, the MFP 10 can belong to both a WFDNW and a normal Wi-Fi NW at the same time.

From the viewpoint of MAC addresses used by the MFP 10, WFD communication and normal Wi-Fi communication can be expressed as follows, for example. That is, WFD communication is wireless communication using the WFD MAC address of the MFP 10 , and normal Wi-Fi communication is wireless communication using the normal Wi-Fi MAC address of the MFP 10 . The WFDNW is a wireless network in which the WFD MAC address of the MFP 10 is used, and the normal Wi-Fi NW is a wireless network in which the normal Wi-Fi MAC address of the MFP 10 is used.

NFCI/F22 is an interface for performing NFC communication. A chip that configures the NFCI/F 22 and a chip that configures the wireless LAN I/F 20 are physically different.

The communication speed of wireless communication via wireless LAN I/F 20 (for example, the maximum communication speed is 11 to 600 Mbps) is higher than the communication speed of wireless communication via NFCI/F 22 (for example, the maximum communication speed is 100 to 424 Kbps). is also fast. Further, the frequency of the carrier wave in wireless communication via the wireless LAN I/F 20 (e.g., 2.4 GHz band, 5.0 GHz band) is the frequency of the carrier wave in wireless communication via the NFCI/F 22 (e.g., 13.56 MHz band) different from Also, for example, when the distance between the MFP 10 and the mobile terminal 50 is approximately 10 cm or less, the control unit 30 can perform NFC communication with the mobile terminal 50 via the NFCI/F 22 . On the other hand, 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 maximum), the control unit 30 controls the mobile terminal 50 via the wireless LAN I/F 20 It is possible to execute WFD communication and normal Wi-Fi communication with the terminal 50 . That is, the maximum distance at which the MFP 10 can perform wireless communication with a communication destination device (for example, the mobile terminal 50) via the wireless LAN I/F 20 is
greater than the maximum distance at which wireless communication can be performed with a device to communicate with via

The control unit 30 has a CPU 32 and a memory 34 . The CPU 32 executes various processes according to programs stored in the memory 34 . The functions of the units 40 to 47 are implemented by the CPU 32 executing processes according to programs. The memory 34 is composed of a ROM, a RAM, a hard disk, and the like. The memory 34 stores the above programs executed by the CPU 32 .

If the MFP 10 belongs to the WFDNW, the memory 34 further stores WFD belonging information indicating that the MFP 10 belongs to the WFDNW. The WFD belonging information includes a state value indicating the state (G/O state or client state) of the MFP 10 in the WFDNW, and WFD wireless settings for executing WFD communication using the WFDNW.

Note that the MFP 10 can form a state in which it belongs to the first WFDNW as a G/O device and belongs to the second WFDNW as a CL device. That is, the MFP 10 can simultaneously belong to two WFDNWs as devices in different states (ie, G/O state, client state). However, the MFP 10 cannot simultaneously belong to two WFDNWs as devices in the same state. That is, when the MFP 10 belongs to one WFDNW as a G/O device, it cannot belong to another WFDNW as a G/O device. Further, while the MFP 10 belongs to one WFDNW as a CL device, it cannot belong to another WFDNW as a CL device. When the MFP 10 belongs to the first and second WFDNWs simultaneously, the memory 34 stores the first WFD belonging information corresponding to the first WFDNW and the second WFD belonging information corresponding to the second WFDNW. Stores both affiliation information and .

The WFD wireless settings include authentication method information, encryption method information, SSID (Service Set Identifier), BSSID (Basic Service Set Identifier), and a password. The SSID included in the WFD wireless settings is a network identifier for identifying the WFDNW. The BSSID included in the WFD wireless settings is a unique identifier (for example, MAC address of the G/O device) assigned to the G/O device of the WFDNW.

The G/O device normally prepares the WFD wireless settings when forming the WFDNW and supplies the WFD wireless settings to the CL device. For example, the control unit 30 of the MFP 10 prepares WFD wireless settings when forming a WFDNW in which the MFP 10 operates as a G/O device. Specifically, the control unit 30 prepares predetermined authentication method information and encryption method information. The control unit 30 prepares a password by preparing a predetermined password or by generating a new password. The control unit 30 prepares an SSID by preparing a predetermined SSID or newly generating an SSID. In addition, the control unit 30 prepares a predetermined MAC address for WFD as a BSSID.

Therefore, when the MFP 10 belongs to a WFDNW as a G/O device, the WFD belonging information corresponding to the WFDNW includes the WFD wireless settings prepared by the MFP 10 when the MFP 10 created the WFDNW. On the other hand, when the MFP 10 belongs to a WFDNW as a CL device, the WFD belonging information corresponding to the WFDNW is set by the G/O device when a G/O device different from the MFP 10 forms the WFDNW. It includes prepared WFD wireless settings (that is, WFD wireless settings obtained from the G/O device).

Further, when the MFP 10 belongs to the normal Wi-Fi NW, the memory 34 further stores normal Wi-Fi belonging information indicating that the MFP 10 belongs to the normal Wi-Fi NW. The normal Wi-Fi belonging information includes normal Wi-Fi wireless settings for performing normal Wi-Fi communication using the normal Wi-Fi NW. Wi-Fi wireless settings typically include authentication scheme information, encryption scheme information, SSID, BSSID, and password. The SSID, which is usually included in Wi-Fi wireless settings, is a network identifier for identifying the Wi-Fi NW. The BSSID, typically included in Wi-Fi radio settings, is a unique identifier (eg, the AP's MAC address) typically assigned to the APs forming the Wi-Fi NW.

The MFP 10 normally joins the Wi-Fi NW using the following techniques. That is, when a predetermined operation is applied to the operation unit 12, the control unit 30 of the MFP 10 executes an SSID search and transmits the PReq signal. As a result, the control unit 30 receives the PRes signal from each of the APs 4 a and 4 b existing around the MFP 10 . The PRes signal includes authentication method information indicating the authentication method used by the AP that sent the PRes signal, encryption method information indicating the encryption method used by the AP, and encryption method information indicating the encryption method used by the AP. SSID and BSSID. Next, the control unit 30 causes the display unit 14 to display a plurality of SSIDs acquired from a plurality of APs. A user selects one SSID (that is, one AP) from a plurality of SSIDs using the operation unit 12 . The user further uses the operation unit 12 to enter a password.

The control unit 30 uses the authentication method information, the encryption method information, the SSID, and the BSSID acquired from the selected AP, and uses the password input by the user to wirelessly connect with the selected AP. to run. The wireless connection includes communication processing for the MFP 10 to participate in the normal Wi-Fi NW (for example, communication processing for authentication (communication of authentication signal, association signal, etc.)). Thereby, the MFP 10 joins the normal Wi-Fi NW formed by the selected AP. The memory 34 stores each information (authentication method information, etc.) used in the wireless connection with the selected AP as normal Wi-Fi wireless settings.

(Configuration of mobile terminal 50)
The mobile terminal 50 is, for example, a portable terminal device such as a mobile phone (for example, a smart phone), a PDA, a notebook PC, a tablet PC, a mobile music player, or a mobile video player. The mobile terminal 50 can perform NFC communication, WFD communication, and normal Wi-Fi communication.

The mobile terminal 50 includes an operation unit 52 , a display unit 54 , a wireless LAN I/F 60 , an NFCI/F 62 and a control unit 70 . Each part 52 to 70 is connected to a bus line (reference numerals omitted). The operation unit 52 has a plurality of keys. The user can input various instructions to the mobile terminal 50 by operating the operation unit 52 . The display unit 54 is a display for displaying various information.

The wireless LAN I/F 60 is an interface for executing WFD communication and normal Wi-Fi communication. NFCI/F62 is an interface for performing NFC communication. Differences between these interfaces 60 and 62 are similar to the differences between interfaces 20 and 22 of MFP 10 . That is, for example, the communication speed of wireless communication via wireless LAN I/F 60 is faster than the communication speed of wireless communication via NFCI/F 62 .

The control unit 70 has a CPU 72 and a memory 74 . The CPU 72 executes various processes according to programs stored in the memory 74 . Programs in memory 74 include applications 76 that cause MFP 10 to perform various functions (eg, print functions, scan functions, etc.). The application 76 may be installed in the mobile terminal 50 from a server provided by the vendor of the MFP 10, or may be installed in the mobile terminal 50 from media shipped with the MFP 10, for example. The functions of the units 80 to 82 are implemented by the CPU 72 executing processing according to the application 76 .

Note that, unlike the MFP 10, the mobile terminal 50 cannot belong to the WFDNW and the normal Wi-Fi NW at the same time. Also, the mobile terminal 50 cannot belong to two WFDNWs at the same time. When the mobile terminal 50 belongs to a WFDNW or a normal Wi-Fi NW, the memory 34 stores WFD belonging information or normal Wi-Fi belonging information similarly to the MFP 10 .

(Configuration of APs 4a and 4b)
Each AP 4a, 4b is not a WFD G/O device, but a normal AP called a wireless access point or a wireless LAN router, and normally forms a Wi-Fi NW. Each AP 4a, 4b receives target data from a first device (for example, a mobile terminal 50) out of a plurality of devices belonging to a normal Wi-Fi NW, and receives target data from a second device out of the plurality of devices. (for example, MFP 10) to transmit the target data. That is, each AP 4a, 4b can perform a relay function of relaying wireless communication of target data between a pair of devices belonging to a normal Wi-Fi NW. In addition, each AP 4a, 4b can perform a router function that relays data communication between devices normally belonging to the Wi-Fi NW and the Internet.

The differences between the WFD G/O equipment and the normal APs (that is, each AP 4a, 4b) are as follows. A WFD G/O device can operate in a state (ie client state) different from the G/O state when it leaves the WFDNW to which it belongs and newly belongs to another WFDNW. In contrast, a regular AP performs the relay function no matter which regular Wi-Fi NW it forms. That is, a normal AP can only perform the same operation as a WFD G/O device, and cannot perform the same operation as a WFD CL device.

The administrator of the communication system 2 can select ON or OFF as the privacy separator setting (hereinafter referred to as "PS (Privacy Separator) setting") of each AP 4a, 4b. For example, when the PS setting of AP 4a is OFF, AP 4a can perform both router function and relay function. On the other hand, when the PS setting of AP 4a is ON, AP 4a can perform the router function, but cannot perform the relay function. In this way, when the PS setting of AP 4a is ON, data communication is not executed between a pair of devices belonging to the normal Wi-Fi NW formed by AP 4a, so the security of the normal Wi-Fi NW can be enhanced. can be done.

(Communication processing executed by MFP 10)
Next, the contents of communication processing executed by the MFP 10 will be described with reference to FIG. While the power of the MFP 10 is ON, the NFCI/F 22 of the MFP 10 emits detection radio waves for detecting a device capable of executing NFC communication (that is, the mobile terminal 50). The user of the mobile terminal 50 brings the mobile terminal 50 close to the MFP 10 after performing an operation of selecting the print function or the scan function. As a result, the distance between the mobile terminal 50 and the MFP 10 becomes smaller than the distance (for example, 10 cm) at which radio waves reach each other. In this case, the NFCI/F 62 of the mobile terminal 50 receives the detected radio wave from the MFP 10 and transmits the response radio wave to the MFP 10 . As a result, an NFC communication session is established between MFP 10 and mobile terminal 50 . Mobile terminal 50 transmits the request data to MFP 10 using the NFC communication session.

As shown in S10, the specific data receiving unit 40 of the MFP 10 monitors reception of request data from the mobile terminal 50 (S10). When receiving the request data from the portable terminal 50 via the NFCI/F 22, the specific data receiving unit 40 determines YES in S10 and proceeds to S12. Note that when the user of the mobile terminal 50 selects the print function, the request data includes a print instruction. On the other hand, when the scan function is selected by the user of mobile terminal 50, the request data includes a scan instruction. Also, if the mobile terminal 50 belongs to a WFDNW or a normal Wi-Fi NW, the request data further includes the SSID of the wireless network to which the mobile terminal 50 belongs. If the mobile terminal 50 belongs to neither the WFDNW nor the normal Wi-Fi NW, the request data does not contain the SSID.

(Response transmission processing; Fig. 3)
In S12, the control unit 30 executes response transmission processing. A WFDNW in which the MFP 10 operates as a G/O device is hereinafter referred to as "WFDNW (MFP=G/O)". A WFDNW in which the MFP 10 operates as a CL device is described as "WFDNW (MFP=CL)".

As shown in FIG. 3, in S30, control unit 30 determines whether MFP 10 belongs to WFDNW (MFP=G/O). Specifically, when the WFD belonging information is not stored in the memory 34, the control unit 30 determines NO in S30 (that is, the MFP 10 does not belong to WFDNW (MFP=G/O)). and proceed to S40. In addition, when two pieces of WFD belonging information are stored in the memory 34, that is, the MFP 10 belongs to the first WFDNW (MFP=G/O) and the MFP 10 belongs to the second WFD NW. If it belongs to WFDNW (MFP=CL), it is determined YES in S30 (that is, MFP 10 belongs to WFDNW (MFP=G/O)), and the process proceeds to S32. Further, when one piece of WFD belonging information is stored in the memory 34, the control unit 30 determines whether the state value included in the WFD belonging information is a value indicating the G/O state. Confirm. If the state value indicates the G/O state, the control unit 30 determines YES in S30 and proceeds to S32, and if the state value indicates the client state, NO in S30. Then, the process proceeds to S40.

In S32, the second determination unit 46 determines whether the request data received from the mobile terminal 50 in S10 of FIG. 2 includes the SSID of the wireless network to which the mobile terminal 50 belongs. If the request data includes the SSID, the second determination unit 46 determines YES in S32 and proceeds to S34, and if the request data does not include the SSID, determines NO in S32 and proceeds to S60. proceed to

In S34, the second determination unit 46 determines whether the MFP 10 belongs to the normal Wi-Fi NW. Specifically, if the memory 34 stores the normal Wi-Fi belonging information, the second determination unit 46 returns YES in S34 (that is, the MFP 10 belongs to the normal Wi-Fi NW). , and proceeds to S36. If the normal Wi-Fi belonging information is not stored in the memory 34, the second determination unit 46 determines NO in S34 (that is, the MFP 10 does not belong to the normal Wi-Fi NW), and determines in S60. proceed to

In S36, the second determination unit 46 determines whether the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW. Specifically, the second determination unit 46 determines whether the SSID included in the normal Wi-Fi belonging information in the memory 34 matches the SSID included in the request data. When the second determination unit 46 determines that the two SSIDs match, it determines YES in S36 (that is, the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW), and proceeds to S50. . On the other hand, when the second determination unit 46 determines that the two SSIDs do not match, it determines NO in S36 (that is, the MFP 10 and the mobile terminal 50 do not belong to the same normal Wi-Fi NW). , S60.

In S50, the first information transmitter 41 first generates response data. Specifically, the first information transmitting unit 41 causes the normal Wi-Fi wireless setting included in the normal Wi-Fi belonging information in the memory 34 to correspond to the priority information indicating the first priority. Generate the attached first correspondence information. Next, the first information transmitting unit 41 selects one or more pieces of WFD belonging information in the memory 34, WFD belonging information including a state value indicating the G/O state (hereinafter referred to as “WFD belonging information for G/O”). ) are identified. Then, the first information transmitting unit 41 transmits second correspondence information in which the WFD wireless setting included in the WFD belonging information for G/O and the priority information indicating the second priority are associated with each other. Generate. The first information transmitter 41 generates response data including the first correspondence information and the second correspondence information. In S50, the first information transmission unit 41 further transmits the generated response data to the mobile terminal 50 via the NFCI/F22. In FIG. 3, the wireless setting, the first priority, and the second priority are indicated as "WS (abbreviation for Wireless Setting)", "(1)", and "(2)", respectively. ing.

Note that, as described above, in S50, the normal Wi-Fi wireless setting corresponding to the normal Wi-Fi NW to which the portable terminal 50 belongs has the first priority. For this reason, the mobile terminal 50 preferentially uses the normal Wi-Fi NW in the application processing of FIG. 4, which will be described later. At this time, since the mobile terminal 50 already belongs to the normal Wi-Fi NW, the mobile terminal 50 does not need to execute connection processing (S210 in FIG. 4) (YES in S208 in FIG. 4). Therefore, the processing load on the mobile terminal 50 can be reduced.

In S60, which is executed in the case of NO in S32, S34, or S36, the first information transmitting unit 41 identifies WFD belonging information for G/O among the one or more pieces of WFD belonging information in the memory 34. do. Then, the first information transmitting unit 41 generates response data including the WFD wireless settings included in the WFD belonging information for G/O. Unlike S50, in S60 the response data does not typically include Wi-Fi wireless configuration and priority information. In S60, the first information transmission unit 41 further transmits the generated response data to the mobile terminal 50 via the NFCI/F22.

On the other hand, in S40, the first determination unit 45 determines whether the request data received from the mobile terminal 50 in S10 of FIG. 2 includes the SSID of the wireless network to which the mobile terminal 50 belongs. If the request data includes the SSID, the first determination unit 45 determines YES in S40 and proceeds to S42, and if the request data does not include the SSID, determines NO in S40 and proceeds to S48. proceed to

In S42, the first determination unit 45 determines whether the MFP 10 belongs to at least one of the normal Wi-Fi NW and the WFDNW (MFP=CL). Specifically, the first determination unit 45 determines at least the normal Wi-Fi affiliation information and the WFD affiliation information including the state value indicating the client state (hereinafter referred to as “CL WFD affiliation information”). If one of them is stored in the memory 34, it determines YES in S42 (that is, the MFP 10 belongs to at least one of the normal Wi-Fi NW and WFDNW (MFP=CL)), and proceeds to S44. move on. If neither the normal Wi-Fi affiliation information nor the WFD affiliation information for CL is stored in the memory 34, the first determination unit 45 determines NO in S42 (that is, if the MFP 10 is normal Wi-Fi NW and WFDNW). (does not belong to any of MFP=CL)), and proceeds to S48.

In S44, the first determination unit 45 determines whether or not the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW when normal Wi-Fi belonging information is stored in the memory 34. A first determination process is executed to The first determination process is the same as S36. When the first determination unit 45 determines in the first determination process that the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW, it determines YES in S44 and proceeds to S46.

In S44, the first determination unit 45 further determines whether the MFP 10 and the mobile terminal 50 belong to the same WFDNW (MFP=CL) when the WFD belonging information for CL is stored in the memory 34. A second judgment process for judging whether or not is executed. Specifically, the first determination unit 45 determines whether the SSID included in the WFD belonging information for CL in the memory 34 matches the SSID included in the request data. The first determination unit 45 determines that the MFP 10 and the mobile terminal 50 belong to the same WFDNW (MFP=CL) when the two SSIDs match. When the first determination unit 45 determines in the second determination process that the MFP 10 and the portable terminal 50 belong to the same WFDNW (MFP=CL), it determines YES in S44 and proceeds to S46. .

On the other hand, the first determination unit 45 determines that the MFP 10 and the mobile terminal 50 do not belong to the same normal Wi-Fi NW in the first determination process, and determines that the MFP 10 and the mobile terminal 50 do not belong to the same normal Wi-Fi NW in the second determination process. 50 do not belong to the same WFDNW (MFP=CL), it is determined NO in S44 and the process proceeds to S48.

In S46, the formation unit 44 shifts the MFP 10 to the autonomous G/O mode. As described above, when a new WFD network is to be formed, G/O negotiation is normally performed to determine the G/O device and the CL device. On the other hand, in the autonomous G/O mode, it is determined that the MFP 10 is the G/O device without executing the G/O negotiation. At the stage of S46, the MFP 10 is the G/O device, but there is no CL device. That is, the forming unit 44 forms a WFDNW (MFP=G/O) to which only the G/O device (that is, the MFP 10) belongs by executing S46.

The autonomous G/O mode is a mode in which the MFP 10 maintains operating in the G/O state. For example, when the MFP 10 enters the G/O state in G/O negotiation and forms a WFD network, when the CL device disappears from the WFD network, the MFP 10 shifts from the G/O state to the device state (that is, , the WFD network disappears). On the other hand, for example, when the MFP 10 enters the G/O state in the autonomous G/O mode and forms a WFD network, the MFP 10 maintains the G/O state (that is, maintain the WFD network).

It should be noted that there is a possibility that the MFP 10 belongs to WFDNW (MFP=CL) when S46 is started. In this case, in S46, the forming unit 44 newly forms a WFDNW (MFP=G/O) without separating the MFP 10 from the WFDNW (MFP=CL). That is, a state is formed in which the MFP 10 simultaneously belongs to two WFDNWs. This point also applies to S48, which will be described later.

In S46, the formation unit 44 further prepares WFD wireless settings (that is, authentication method information, encryption method information, SSID, BSSID, and password) to be used in WFDNW (MFP=G/O). Techniques for preparing WFD radio settings are described above. In S<b>46 , the formation unit 44 further causes the memory 34 to store G/O WFD affiliation information including the state value indicating the G/O state and the prepared WFD wireless settings. After completing S46, the process proceeds to S70.

In S70, the second information transmitter 42 first generates response data. Specifically, the second information transmission unit 42 selects from among one or more pieces of belonging information (that is, normal Wi-Fi belonging information, WFD belonging information) in the memory 34, both the MFP 10 and the portable terminal 50 belongs to (i.e., the wireless network determined as YES in S44) (hereinafter referred to as "specific belonging information"). The specific affiliation information is usually Wi-Fi affiliation information or WFD affiliation information for CL. Then, the second information transmitting unit 42 sets the wireless setting (that is, the normal Wi-Fi wireless setting or the WFD wireless setting of WFDNW (MFP=CL)) included in the specific affiliation information, and the first priority First correspondence information in which is associated with priority order information indicating and is generated. Next, the second information transmitting unit 42 sets the WFD wireless settings included in the WFD belonging information for G/O in the memory 34 (that is, the WFD wireless settings prepared in S46) and the priority indicating the second priority. and generate second correspondence information in which the information and are associated with each other. The second information transmission unit 42 generates response data including the first correspondence information and the second correspondence information. In S70, the second information transmission unit 42 further transmits the generated response data to the mobile terminal 50 via the NFCI/F22.

As described above, in S70, the wireless setting corresponding to the wireless network to which the mobile terminal 50 belongs has the first priority. For this reason, the mobile terminal 50 preferentially uses the wireless network in the application processing of FIG. 4, which will be described later. At this time, since the mobile terminal 50 already belongs to the wireless network, the mobile terminal 50 does not need to perform connection processing (S210 in FIG. 4) (YES in S208 in FIG. 4). Therefore, the processing load on the mobile terminal 50 can be reduced.

On the other hand, in S48, the formation unit 44 shifts the MFP 10 to the autonomous G/O mode. S48 is similar to S46. Next, in S60 executed through S48, the third information transmitting unit 43 includes the WFD wireless settings included in the WFD belonging information for G/O in the memory 34 (that is, the WFD wireless settings prepared in S48). Generate response data. Unlike S70, in S60, the response data does not include the normal Wi-Fi wireless setting or the WFD wireless setting corresponding to WFDNW (MFP=CL), and does not include priority information. In S60 executed after S48, the third information transmission unit 43 further transmits the generated response data to the mobile terminal 50 via the NFCI/F22.

As described above, even if the MFP 10 belongs to the normal Wi-Fi NW, if the portable terminal 50 does not belong to the normal Wi-Fi NW (NO in S36 or NO in S44), the MFP 10 may The normal Wi-Fi wireless settings corresponding to the Wi-Fi NW are not transmitted to the mobile terminal 50 (S60). Therefore, it is possible to prevent the security of the normal Wi-Fi NW to which the MFP 10 belongs from being degraded. Similarly, even if the MFP 10 belongs to the WFDNW (MFP=CL), if the portable terminal 50 does not belong to the WFDNW (MFP=CL) (NO in S44), the MFP 10 ) is not transmitted to the mobile terminal 50 (S60). For this reason, it is possible to prevent deterioration of the security of the WFDNW (MFP=CL) to which the MFP 10 belongs.

On the other hand, in the WFDNW (MFP=G/O) to which the MFP 10 belongs, there is no problem even if the MFP 10 decides the security policy of the WFDNW. For this reason, in this embodiment, even if the mobile terminal 50 does not belong to the WFDNW (MFP=G/O), the MFP 10 sets the WFD wireless settings corresponding to the WFDNW (MFP=G/O). It is transmitted to the mobile terminal 50 (S50, S60, S70). As a result, although details will be described later, the MFP 10 and the mobile terminal 50 can appropriately execute communication of the target data using the WFDNW (MFP=G/O).

(Processing after S14 in FIG. 2)
When S50, S60, or S70 in FIG. 3 is executed, the response transmission process in FIG. 3 ends. In this case, the process proceeds to S14 in FIG. The WFD wireless settings corresponding to WFDNW (MFP=G/O) are transmitted to the mobile terminal 50 regardless of which of S50, S60, and S70 in FIG. 3 is executed. Although details will be described later, when the mobile terminal 50 does not belong to the WFDNW (MFP=G/O), the mobile terminal 50 uses the WFD wireless settings to establish connection for joining the WFDNW (MFP=G/O). A signal (for example, an Authentication Request signal, an Association Request signal) is transmitted to the MFP 10 (see S210 in FIG. 4). At S14, the control unit 3
0 monitors reception of a connection signal from the mobile terminal 50 via the wireless LAN I/F 20 . When the connection signal is received from the mobile terminal 50, the control unit 30 determines YES in S14 and proceeds to S16. If NO in S14, the process proceeds to S18.

In S<b>16 , the control unit 30 transmits a connection response signal (for example, an Authentication Response signal, an AssociationResponse signal), which is a response signal to the connection signal, to the mobile terminal 50 via the wireless LAN I/F 20 . As a result, the mobile terminal 50 can use the WFDNW (MF
P=G/O). That is, the MFP 10 and the portable terminal 50 belong to the same WFDNW (MFP=G/O). After completing S16, the process proceeds to S18.

Further, although details will be described later, the mobile terminal 50 uses the wireless network to which both the MFP 10 and the mobile terminal 50 belong to transmit a confirmation signal (for example, a PING signal) to the MFP 10 (see S212 in FIG. 4). . In S<b>18 , the communication executing unit 47 monitors reception of a confirmation signal from the mobile terminal 50 via the wireless LAN I/F 20 . When the confirmation signal is received from the mobile terminal 50, the communication execution unit 47 determines YES in S18, and proceeds to S20. If NO in S18, the process returns to S14.

In S<b>20 , the control unit 30 transmits a confirmation response signal (for example, a PING Response signal), which is a response signal to the confirmation signal, to the mobile terminal 50 via the wireless LAN I/F 20 .
After completing S20, the process proceeds to S22.

Note that even if a confirmation signal is transmitted from mobile terminal 50 to MFP 10 using a wireless network to which both MFP 10 and mobile terminal 50 belong (hereafter referred to as “both belonging NW”), MFP 10 does not receive the confirmation signal. may not be able to receive For example, in a situation where both NWs are normal Wi-Fi NWs, if the PS setting of the AP forming the normal Wi-Fi NW is ON, the AP receives the confirmation signal from the mobile terminal 50. However, the confirmation signal is not transmitted to the MFP 10. Further, for example, in a situation where both NWs belong to a WFDNW (that is, WFDNW (MFP=CL, mobile terminal=CL)) in which both the MFP 10 and the mobile terminal 50 operate as CL devices, the WFDNW (MFP=CL, mobile terminal=CL) When the PS setting of the G/O device forming the mobile terminal (CL) is ON, the G/O device transmits the confirmation signal to the MFP 10 even if it receives the confirmation signal from the mobile terminal 50. do not do. In this way, even if both serving NWs are used, there is a possibility that the communication of the acknowledgment signal and the acknowledgment signal cannot be executed. When such a dual-affiliated NW is used, communication of target data (ie, print data or scan data) is also impossible.

On the other hand, when both of the affiliated NWs are WFDNW (MFP=G/O), the MFP 10 and the mobile terminal 50 do not execute communication via a relay device (that is, AP or G/O device). , to carry out communication directly. Therefore, an event that data communication is not successful due to the PS setting of the relay device being ON does not occur. Also, even in a situation where both NWs belong to a normal Wi-Fi NW or WFDNW (MFP=CL, mobile terminal=CL), if the PS setting of the relay device is OFF, the communication of the confirmation signal and the confirmation response signal is executed. It is possible. When such a dual-affiliated NW is used, communication of target data (that is, print data or scan data) can be executed.

In view of such circumstances, in S22, the communication execution unit 47 uses the wireless network (hereinafter referred to as "specific wireless network") in which the communication of the confirmation signal and the confirmation response signal has succeeded, and the wireless LAN I/ Communication of target data is executed via F20. As a result, the MFP 10 and the portable terminal 50 can appropriately communicate the target data. For example, in S22 executed through S50 in FIG. 3, the normal Wi-Fi NW or WFDNW (MFP=G/O) is the above specific wireless network. Also, for example, in S22 executed through S60 in FIG. 3, WFDNW (MFP=G/O) is the specific wireless network. Also, for example, in S22 executed through S70 in FIG. 3, the normal Wi-Fi NW, WFDNW (MFP=CL), or WFDNW (MFP=G/O) is the above specific wireless network.

For example, when the request data received in S10 includes a print instruction, in S22, the communication execution unit 47 uses the above-described specific wireless network to send the request from the mobile terminal 50 via the wireless LAN I/F 20. Receive print data. Next, the control unit 30 supplies print data (that is, target data) to the print execution unit 16 . As a result, the print execution unit 16 prints the image represented by the print data on the print medium. Further, when the request data received in S10 includes a scan instruction, the control unit 30 activates the scan execution unit 18 in S22. As a result, the scan execution unit 18 scans the document and generates scan data. Next, the communication executing unit 47 transmits the scan data (that is, the target data) to the mobile terminal 50 via the wireless LAN I/F 20 using the specific wireless network. When S22 ends, the process returns to S10.

Print data or scan data usually has a larger data size than each data (for example, request data, response data) communicated by NFC communication. As described above, the communication speed of NFC communication is slower than that of WFD communication or normal Wi-Fi communication. Therefore, if a configuration is adopted in which wireless communication of target data is performed using NFC communication between the MFP 10 and the mobile terminal 50, it takes a long time to wirelessly communicate the target data. In view of such circumstances, in this embodiment, the MFP 10 transmits response data to the portable terminal 50 for performing wireless communication of target data by WFD communication or normal Wi-Fi communication. Thereby, the MFP 10 and the portable terminal 50 can perform WFD communication or normal Wi-Fi communication of the target data, and as a result, wireless communication of the target data can be performed quickly.

(Application processing of portable terminal 50; FIG. 4)
Next, with reference to FIG. 4, the contents of the processing executed by the control unit 70 of the mobile terminal 50 according to the application 76 will be described. When the user of the mobile terminal 50 desires to have the MFP 10 execute the print function or the scan function, the user operates the operation unit 52 to activate the application 76 . Thereby, the control unit 70 starts the flowchart of FIG. 4 according to the application 76 .

The user operates the operation unit 52 to select a function (printing function or scanning function) to be executed by the MFP 10 . When selecting the print function, the user further operates the operation unit 52 to select data to be printed (that is, print data) stored in the memory 74 of the mobile terminal 50 . If the user selects the print function or the scan function, the control unit 70 determines YES in S200 and proceeds to S202.

In S202, the specific data transmission unit 80 first generates request data including an instruction (print instruction or scan instruction) corresponding to the selected function. Further, when the memory 74 stores normal Wi-Fi affiliation information or WFD affiliation information, the specific data transmission unit 80 identifies the SSID included in the affiliation information. Then, the specified data transmission unit 80 generates request data including the specified SSID. In S<b>202 , specific data transmission unit 80 also monitors whether an NFC communication session is established between MFP 10 and mobile terminal 50 . Specific data transmission unit 80 transmits the generated request data to MFP 10 via NFC I/F 62 when an NFC communication session is established. Thereby, the MFP 10 receives the request data (see S10 in FIG. 2).

As described above, the MFP 10 transmits the response data to the mobile terminal 50 in S50, S60, or S70 of FIG. As a result, in S204, the information receiving unit 81 receives the response data from the MFP 10 via the NFCI/F62.

Next, in S206, the communication executing unit 82 identifies the wireless setting with the highest priority among the one or more wireless settings included in the response data received in S204. For example, when the response data includes WFD wireless settings corresponding to WFDNW (MFP=G/O) and does not include other wireless settings (see S60 in FIG. 3), the communication executing unit 82 Identify settings. Further, for example, when the response data includes two wireless settings (see S50 and S70 in FIG. 3), in the first S206, the communication execution unit 82 sets the priority information indicating the first priority to Identify the associated radio settings. Note that this wireless setting matches the wireless setting included in the belonging information in the memory 74, that is, the wireless setting corresponding to the wireless network to which the portable terminal 50 belongs. This is because in S50 or S70 of FIG. 3, the wireless settings corresponding to the wireless network to which both the MFP 10 and the mobile terminal 50 belong are associated with the priority information indicating the first priority.

Next, in S208, the communication executing unit 82 determines whether or not the mobile terminal 50 belongs to the wireless network corresponding to the wireless setting specified in S206 (hereinafter referred to as "target wireless network"). . Specifically, when the wireless setting specified in S206 matches the wireless setting included in the belonging information in the memory 74, the communication executing unit 82 determines YES in S208, and proceeds to S210. Skip to S212. On the other hand, if the wireless setting specified in S206 and the wireless setting included in the belonging information in the memory 74 do not match, the communication execution unit 82 determines NO in S208 and proceeds to S210.

In S210, the communication execution unit 82 uses the wireless settings identified in S206 to execute connection processing. Specifically, the communication executing unit 82 performs connection for connecting to a target relay device (for example, AP 4a, 4b, or MFP 10 operating as a G/O device) forming a target wireless network. Generate a signal. Next, the communication executing unit 82 transmits a connection signal to the target relay device via the wireless LAN I/F 60, and as a result, receives a connection response signal from the target relay device via the wireless LAN I/F 60. do. Communication of the connection signal and the connection response signal is performed multiple times. For example, an Authentication Request signal is transmitted as a connection signal, and an AuthenticationResponse signal is received as a connection response signal.
Also, for example, an Association Request signal is transmitted as a connection signal, and an Association Response signal is received as a connection response signal. If the target relay device is the MFP 10 operating as a G/O device, the MFP 10 receives the connection signal from the mobile terminal 50 in S14 of FIG. Send to 50.

In the process of communicating the connection signal and the connection response signal, the communication executing unit 82 transmits authentication method information, encryption method information, password, SSID, and BSSID included in the wireless settings specified in S206. As a result, the target relay device authenticates the mobile terminal 50 . If the authentication succeeds, the connection between the mobile terminal 50 and the target relay device is successful, and as a result, the mobile terminal 50 newly participates in the target wireless network. It should be noted that there is a possibility that the portable terminal 50 belongs to an existing wireless network at the stage when S210 is executed.
In this case, the mobile terminal 50 leaves the existing wireless network and newly joins the target wireless network.

Next, in S<b>212 , the communication executing unit 82 uses the wireless network to which the portable terminal 50 belongs to transmit a confirmation signal (for example, a PING signal) to the MFP 10 via the wireless LAN I/F 60 . For example, if YES in S208, the wireless network used in S212 is the existing wireless network to which the mobile terminal 50 belongs at the stage when the application processing in FIG. 4 is started. Also, for example, in the case of NO in S208, the wireless network used in S212 is the wireless network to which the mobile terminal 50 newly joined in the connection processing of S210.

In S<b>214 , communication executing unit 82 monitors reception of an acknowledgment signal (for example, PINGResponse signal) from MFP 10 via wireless LAN I/F 60 . As described above, when the PS setting of the relay device forming the wireless network used for communication of the acknowledgment signal is ON, the communication executing unit 82 does not receive the acknowledgment signal. In this case, the communication executing unit 82 determines NO in S214 and proceeds to S216. On the other hand, when the acknowledgment signal is received, the communication executing unit 82 determines YES in S214 and proceeds to S218.

In S216, the communication executing unit 82 determines whether or not there is a wireless setting that has not been identified in S206 among the one or more wireless settings included in the response data received in S204. If there is no unspecified wireless setting in S206, the communication executing unit 82 determines NO in S216 and proceeds to S220. On the other hand, if there is a wireless setting that has not yet been specified in S206, the communication executing unit 82 determines YES in S216 and executes S206 for the second time.

In the second S206, the communication execution unit 82 identifies the wireless setting having the highest priority among the wireless settings that have not yet been identified in the first S206. In this embodiment, the maximum number of wireless settings included in the response data is "2". Identify the wireless settings that are Note that this wireless setting is a WFD wireless setting corresponding to WFDNW (MFP=G/O). This is because in S50 or S70 of FIG. 3, the WFD wireless setting corresponding to WFDNW (MFP=G/O) is associated with the priority information indicating the second priority. Therefore, when S208 to S214 are executed after that, the communication execution unit 82 normally receives an acknowledgment signal from the MFP 10 in S214. In WFDNW (MFP=G/O), since communication is directly executed without going through a relay device, there is an event that data communication does not succeed due to the PS setting of the relay device being ON. This is because it does not occur.

In S218, the communication executing unit 82 communicates the target data via the wireless LAN I/F 60 using the wireless network in which the confirmation signal and the response signal have been successfully communicated (hereinafter referred to as "specific wireless network"). to run. For example, when the print function is selected in S200, the communication execution unit 82 transmits print data to the MFP 10 via the wireless LAN I/F 60 using the specific wireless network in S218. Further, when the scan function is selected in S200, communication execution unit 82 receives scan data from MFP 10 via wireless LAN I/F 60 using the above-described specific wireless network in S218. In this case, the controller 70 causes the memory 74 to store the scan data. When S218 ends, the application processing in FIG. 4 ends.

Note that in S220, the control unit 70 causes the display unit 54 to display information indicating that communication of the target data with the MFP 10 cannot be executed. When S220 ends, the application processing in FIG. 4 ends. In S210, if the mobile terminal 50 leaves the existing wireless network and joins a new wireless network, the control unit 70 further performs the following process after the application process in FIG. Run. That is, the control unit 70 causes the mobile terminal 50 to leave the wireless network that it joined in S210, and rejoins the mobile terminal 50 to the existing wireless network.

(specific case)
Next, specific cases realized by the MFP 10 and the portable terminal 50 of this embodiment will be described with reference to FIGS. 5 to 8. FIG. 5 to 8, the thin line arrow between the MFP 10 and the mobile terminal 50 indicates NFC communication, and the thick line arrow between the MFP 10 and the mobile terminal 50 indicates WFD communication or normal Wi-Fi communication. The PS setting of AP4a is ON.

(Fig. 5; Case A)
In case A, a WFDNW (MFP=G/O) is formed in which the MFP 10 is the G/O device and the PC 6 is the CL device. In WFDNW (MFP=G/O), WFD wireless setting WS1 including SSID "01" is used. Also, the MFP 10 and the portable terminal 50 belong to the normal Wi-Fi NW formed by the AP 4a. The normal Wi-Fi NW uses the normal Wi-Fi wireless setting WS4 including the SSID "04".

When the print function is selected by the user (YES in S200 of FIG. 4), mobile terminal 50 uses NFC communication to transmit request data including a print instruction and SSID "04" to MFP 10 (S202). .

When the MFP 10 receives the request data from the portable terminal 50 (YES in S10 of FIG. 2), it determines YES in S30 of FIG. 3, determines YES in S32, determines YES in S34, and determines YES in S36. do. As a result, the MFP 10 sets the normal Wi-Fi wireless setting WS4 associated with the priority information indicating the first priority and the WFD wireless setting associated with the priority information indicating the second priority. The response data including WS1 and are transmitted to the mobile terminal 50 using NFC communication (S50).

When the mobile terminal 50 receives the response data from the MFP 10 (S204 in FIG. 4), it specifies the normal Wi-Fi wireless setting WS4 associated with the priority information indicating the first priority (S206). Next, the mobile terminal 50 determines YES in S208, and transmits a confirmation signal to the MFP 10 using the normal Wi-Fi NW (S212). However, since the PS setting of AP 4 a is ON, AP 4 a does not transmit the confirmation signal to MFP 10 even if it receives the confirmation signal from portable terminal 50 . As a result, the mobile terminal 50 does not receive the acknowledgment signal, and determines NO in S214.

Next, the mobile terminal 50 identifies the WFD wireless setting WS1 associated with the priority information indicating the second priority (S206). In this case, the mobile terminal 50 determines NO in S208, uses the WFD wireless setting WS1 to connect to the MFP 10 which is a G/O device, and newly participates in the WFDNW (MFP=G/O) (S210). ). Next, the mobile terminal 50 uses WFDNW (MFP=G/O) to transmit a confirmation signal to the MFP 10 (S212).

In WFDNW (MFP=G/O), the confirmation signal is transmitted to MFP 10 without going through the relay device. Therefore, the MFP 10 uses WFDNW (MFP=G/O) to receive the confirmation signal from the mobile terminal 50 (YES in S18 of FIG. 2). In this case, the MFP 10 uses WFDNW (MFP=G/O) to transmit an acknowledgment signal to the mobile terminal 50 (S20).

When the mobile terminal 50 receives the confirmation signal from the MFP 10 (YES in S214 of FIG. 4), it uses WFDNW (MFP=G/O) to transmit the print data to the MFP 10 (S218). As a result, the MFP 10 receives the print data using the WFDNW (MFP=G/O) (S22 in FIG. 2). As a result, the image represented by the print data is printed on the print medium.

(Fig. 6; Case B)
In Case B, the WFDNW (MFP=G/O) to which the MFP 10 and PC6 belong is the same as the WFDNW in Case A (MFP=G/O). Also, the MFP 10 belongs to the normal Wi-Fi NW formed by AP4a. The normal Wi-Fi NW uses the normal Wi-Fi wireless setting WS4 including the SSID "04". Also, the mobile terminal 50 belongs to the normal Wi-Fi NW formed by the AP 4b. The normal Wi-Fi NW uses the normal Wi-Fi wireless setting WS5 including the SSID "05".

When the print function is selected by the user (YES in S200 of FIG. 4), mobile terminal 50 uses NFC communication to transmit request data including a print instruction and SSID "05" to MFP 10 (see FIG. 4). of S202).

When the MFP 10 receives the request data from the portable terminal 50 (YES in S10 of FIG. 2), it determines YES in S30 of FIG. 3, determines YES in S32, determines YES in S34, and determines NO in S36. do. As a result, the MFP 10 uses NFC communication to transmit response data that includes the WFD wireless setting WS1 and does not include the normal Wi-Fi wireless setting WS4 to the mobile terminal 50 (S60 in FIG. 3).

When the mobile terminal 50 receives the response data from the MFP 10 (S204 in FIG. 4), it identifies the WFD wireless setting WS1 (S206). Next, the portable terminal 50 determines NO in S208, uses the WFD wireless setting WS1, connects to the MFP 10 which is a G/O device, and newly participates in the WFDNW (MFP=G/O) (S210). . The subsequent operations of the MFP 10 and the portable terminal 50 are the same as in case A.

(Fig. 7; Case C)
In case C, as in case A, the MFP 10 and mobile terminal 50 belong to the normal Wi-Fi NW formed by AP 4a. The normal Wi-Fi NW uses the normal Wi-Fi wireless setting WS2 including the SSID "02". The MFP 10 and mobile terminal 50 do not belong to the WFDNW.

When the print function is selected by the user (YES in S200 in FIG. 4), mobile terminal 50 uses NFC communication to transmit request data including a print instruction and SSID "02" to MFP 10 (see FIG. 4). of S202).

When the MFP 10 receives the request data from the portable terminal 50 (YES in S10 of FIG. 2), it determines NO in S30 of FIG. 3, determines YES in S40, determines YES in S42, and determines YES in S44. do. As a result, the MFP 10 shifts to the autonomous G/O mode and forms WFDNW (MFP=G/O) (S46). In WFDNW (MFP=G/O), WFD wireless setting WS3 is used. Next, the MFP 10 sets the normal Wi-Fi wireless setting WS2 associated with the priority information indicating the first priority and the WFD wireless setting WS3 associated with the priority information indicating the second priority. and is transmitted to the mobile terminal 50 using NFC communication (S70).

When the mobile terminal 50 receives the response data from the MFP 10 (S204 in FIG. 4), it identifies the normal Wi-Fi wireless setting WS2 associated with the priority information indicating the first priority (S206). Next, the mobile terminal 50 determines YES in S208, and transmits a confirmation signal to the MFP 10 using the normal Wi-Fi NW (S212). However, since the PS setting of AP 4 a is ON, AP 4 a does not transmit the confirmation signal to MFP 10 even if it receives the confirmation signal from portable terminal 50 . As a result, the mobile terminal 50 does not receive the acknowledgment signal, and determines NO in S214.

Next, the mobile terminal 50 identifies the WFD wireless setting WS3 associated with the priority information indicating the second priority (S206). In this case, the mobile terminal 50 determines NO in S208, uses the WFD wireless setting WS3 to connect to the MFP 10 which is a G/O device, and newly participates in the WFDNW (MFP=G/O) (S210). ). The subsequent operations of the MFP 10 and the portable terminal 50 are the same as in case A.

(Fig. 8; Case D)
In case D, the MFP 10 belongs to the regular Wi-Fi NW formed by AP4a. The normal Wi-Fi NW uses the normal Wi-Fi wireless setting WS2 including the SSID "02". Also, the mobile terminal 50 belongs to the normal Wi-Fi NW formed by the AP 4b. The normal Wi-Fi NW uses the normal Wi-Fi wireless setting WS6 including the SSID "06".

When the print function is selected by the user (YES in S200 in FIG. 4), mobile terminal 50 uses NFC communication to transmit request data including a print instruction and SSID "06" to MFP 10 (see FIG. 4). of S202).

When the MFP 10 receives the request data from the portable terminal 50 (YES in S10 of FIG. 2), it determines NO in S30 of FIG. 3, determines YES in S40, determines YES in S42, and determines NO in S44. do. As a result, the MFP 10 shifts to the autonomous G/O mode and forms WFDNW (MFP=G/O) (S48). In WFDNW (MFP=G/O), WFD wireless setting WS3 is used. Next, the MFP 10 transmits response data including the WFD wireless setting WS3 and not including the normal Wi-Fi wireless setting WS2 to the mobile terminal 50 using NFC communication (S60).

When the mobile terminal 50 receives the response data from the MFP 10 (S204 in FIG. 4), it identifies the WFD wireless setting WS3 (S206). Next, the mobile terminal 50 determines NO in S208, uses the WFD wireless setting WS3, connects to the MFP 10 which is a G/O device, and newly participates in the WFDNW (MFP=G/O) (S210). . The subsequent operations of the MFP 10 and the portable terminal 50 are the same as in case A.

(Effect of the first embodiment)
As shown in cases A and B in FIGS. 5 and 6, when the MFP 10 belongs to the WFDNW (MFP=G/O), the WFD wireless setting WS1 corresponding to the WFDNW (MFP=G/O) to the mobile terminal 50 . For this reason, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the WFDNW (MFP=G/O).

Incidentally, when the MFP 10 belongs not only to the WFDNW (MFP=G/O) but also to the normal Wi-Fi NW, it is classified into case A and case B. FIG. That is, in case A of FIG. 5, since the MFP 10 and the mobile terminal 50 belong to the same normal Wi-Fi NW, the MFP 10 has the normal Wi-Fi wireless setting WS4 corresponding to the normal Wi-Fi NW and the WFDNW (
and a WFD wireless setting WS1 corresponding to MFP=G/O) are transmitted to the mobile terminal 50 . As a result, the MFP 10 and the portable terminal 50 can appropriately communicate the target data using the normal Wi-Fi NW or WFDNW (MFP=G/O). In particular, in case A, the PS setting of the AP 4a is ON, so the MFP 10 and the mobile terminal 50 cannot communicate the target data using the normal Wi-Fi NW. However, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the WFDNW (MFP=G/O).

In case B of FIG. 6, since the MFP 10 and the mobile terminal 50 do not belong to the same normal Wi-Fi NW, the MFP 10 transmits the normal Wi-Fi wireless settings WS4 corresponding to the normal Wi-Fi NW to the mobile terminal 50. Instead, the WFD wireless setting WS1 corresponding to WFDNW (MFP=G/O) is transmitted to the mobile terminal 50 . As a result, it is possible to prevent deterioration of the security of the normal Wi-Fi NW to which the MFP 10 belongs. Moreover, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the WFDNW (MFP=G/O).

Further, as shown in case C of FIG. 7, the MFP 10 does not belong to the WFDNW (MFP=G/O), but if it belongs to the normal Wi-Fi NW, the WFDNW (MFP=G/O) form anew. Since the MFP 10 and the portable terminal 50 belong to the same normal Wi-Fi NW, the MFP 10 has the normal Wi-Fi wireless setting WS2 corresponding to the normal Wi-Fi NW and the WFD wireless setting corresponding to the WFDNW (MFP=G/O). to the portable terminal 50. As a result, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the normal Wi-Fi NW or WFDNW (MFP=G/O). In particular, in case C, the PS setting of the AP 4a is ON, so the MFP 10 and the mobile terminal 50 cannot communicate the target data using the normal Wi-Fi NW. However, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the WFDNW (MFP=G/O).

Further, as shown in case D of FIG. 8, since the MFP 10 and the portable terminal 50 do not belong to the same normal Wi-Fi NW, the MFP 10 carries the normal Wi-Fi wireless setting WS2 corresponding to the normal Wi-Fi NW. WFD wireless setting WS3 corresponding to WFDNW (MFP=G/O) is transmitted to the mobile terminal 50 without transmitting to the terminal 50 . Therefore, it is possible to prevent the security of the normal Wi-Fi NW to which the MFP 10 belongs from being degraded. Moreover, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the WFDNW (MFP=G/O).

The case of YES in S36 or YES in S44 of FIG. 3 is an example of the "third case", and the case of NO in S36 or NO in S44 is the "fourth case". is an example.

(Second embodiment)
In this embodiment, the content of the response transmission process (FIG. 3) of S12 of FIG. 2 is different from that of the first embodiment. As described above, in the first embodiment, if the MFP 10 and the mobile terminal 50 do not belong to the same normal Wi-Fi NW (NO in S36 or NO in S44 in FIG. 3), the MFP 10 performs normal Wi-Fi wireless settings. It is not transmitted to the mobile terminal 50 (S60). Also, if the MFP 10 and the mobile terminal 50 do not belong to the same WFDNW (MFP=CL) (NO in S44), the MFP 10 does not transmit the WFD wireless settings corresponding to the WFDNW (MFP=CL) to the mobile terminal 50 ( S60). On the other hand, in this embodiment, the MFP 10 supports all wireless networks capable of communicating target data with the mobile terminal 50 regardless of whether the MFP 10 and the mobile terminal 50 belong to the same wireless network. All wireless settings to be performed are transmitted to the mobile terminal 50 .

S130 and S132 in FIG. 9 are the same as S30 and S34 in FIG. If YES in S132, the MFP 10 belongs to the normal Wi-Fi NW and WFDNW (MFP=G/O). In this case, in S150, the first information transmitting unit 41 performs the same processing as in S50 of FIG. If NO in S132, the MFP 10 belongs to WFDNW (MFP=G/O). In this case, in S160, the first information transmitting unit 41 performs the same processing as in S60 of FIG.

S134 is the same as S132. If YES in S134, the control unit 30 determines in S136 whether the MFP 10 belongs to the WFDNW (MFP=CL). The determination method of S136 is the same as the determination method used in S42 of FIG. The formation unit 44 executes S138 if S136 is YES, and executes S140 if S136 is NO. S138 and S140 are the same as S46 (or S48) in FIG.

When S138 is executed, the MFP 10 belongs to the normal Wi-Fi NW, WFDNW (MFP=CL), and WFDNW (MFP=G/O). In S170 executed through S138, the second information transmitting unit 42 associates the normal Wi-Fi wireless setting corresponding to the normal Wi-Fi NW with priority information indicating the first priority. 1st correspondence information is generated. The second information transmitting unit 42 further generates second correspondence information in which the WFD wireless setting corresponding to WFDNW (MFP=CL) and priority information indicating the second priority are associated with each other. do. The second information transmitting unit 42 further provides third correspondence information in which the WFD wireless setting corresponding to WFDNW (MFP=G/O) is associated with priority information indicating the third priority. to generate Then, the second information transmitting unit 42 generates response data including the first correspondence information, the second correspondence information, and the third correspondence information. In S170, the second information transmission unit 42 further transmits the generated response data to the mobile terminal 50 via the NFCI/F22.

At the stage of S170, the mobile terminal 50 cannot belong to the WFDNW (MFP=G/O). This is because the WFDNW (MFP=G/O) is the new WEDNW created by the MFP 10 in S138. However, at the stage of S170, there is a possibility that the mobile terminal 50 usually belongs to the Wi-Fi NW or WFDNW (MFP=CL). Therefore, in this embodiment, in S170, the response data is generated so that the priority of the normal Wi-Fi NW and WFDNW (MFP=CL) is higher than the priority of WFDNW (MFP=G/O). . This can increase the possibility that the mobile terminal 50 does not need to perform the connection process of S210 of FIG. In the modified example, in S170, the second information transmitting unit 42 sets the priority of the WFDNW (MFP=CL) to the first priority, and the priority of the normal Wi-Fi NW to the second priority. You may generate the response data so that

When S140 is executed, the MFP 10 belongs to the normal Wi-Fi NW and WFDNW (MFP=G/O). S180, which is executed after S140, is similar to S70 in FIG. 3, in which the Wi-Fi NW is normally adopted as the first priority.

S142 is similar to S136. If S142 is YES, the formation unit 44 executes S144, and if S142 is NO, executes S146. S144 and S146 are the same as S46 (or S48) in FIG.

When S144 is executed, the MFP 10 belongs to WFDNW (MFP=CL) and WFDNW (MFP=G/O). S190 executed after S144 is the same as S70 of FIG. 3 in which WFDNW (MFP=CL) is adopted as the first priority.

When S146 is executed, the MFP 10 belongs to WFDNW (MFP=G/O). S160 executed after S146 is the same as S60 in FIG.

(Effect of the second embodiment)
In this embodiment, when the MFP 10 belongs to the WFDNW (MFP=G/O) (YES in S130), the MFP 10 transmits the WFD wireless settings corresponding to the WFDNW (MFP=G/O) to the mobile terminal 50 ( S150, S160). For this reason, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the WFDNW (MFP=G/O). Also, if the MFP 10 does not belong to a WFDNW (MFP=G/O) but belongs to another wireless network (normal Wi-Fi NW or WFDNW (MFP=CL)) (YES in S134, or YES in S142), a new WFDNW (MFP=G/O) is formed, and the wireless setting (normal Wi-Fi wireless setting or WFDNW (MFP=CL) corresponding to the above other wireless network is created). WFD wireless settings) and WFD wireless settings corresponding to WFDNW (MFP=G/O) are transmitted to the mobile terminal 50 (S170,
S180, S190). For this reason, the MFP 10 and the mobile terminal 50 can appropriately communicate the target data using the above-mentioned other wireless network or WFDNW (MFP=G/O). Even if the MFP 10 and the mobile terminal 50 cannot execute the communication of the target data using the above-mentioned other wireless network, the MFP 10 and the mobile terminal 50 can access the WFDNW formed by the MFP 10 (MFP=G /O) can be used to properly execute the communication of the target data.

(correspondence relationship)
The case of YES in S130 is an example of the "first case." That is, WFDNW (MFP=G/O) is an example of the "first wireless network". A case of YES in S134 or a case of YES in S142 is an example of the "second case." That is, the normal Wi-Fi NW or WFDNW (MFP=CL) is an example of the "second wireless network". Also, the WFDNW (MFP=G/O) formed in S138, S140, or S146 is an example of the "third wireless network." Also, S150 or S160 is an example of processing executed by the "first information transmission unit". S170, S180, or S190 is an example of the process executed by the "second information transmission unit".

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

(Modification 1) In case A of FIG. 5, the first information transmission unit 41 of the MFP 10 transmits all information (that is, authentication method information, encryption method information, SSID, BSSID, and , password) to the mobile terminal 50 (S50 in FIG. 3). Alternatively, the first information transmission unit 41 may transmit response data including some information (for example, SSID and password) of the WFD wireless settings WS1 to the mobile terminal 50 . In this case, the communication executing unit 82 of the mobile terminal 50 executes an SSID search (that is, transmits a PReq signal) when the mobile terminal 50 is to newly participate in the WFDNW (MFP=G/O), The PRes signal may be received from the MFP 10 operating as a G/O device. The PRes signal includes each information (that is, authentication method information, encryption method information, SSID and BSSID) used in WFDNW (MFP=G/O). As a result, the communication executing unit 82 can acquire each piece of information (that is, the authentication method information, the encryption method information, and the BSSID) other than the part of the information included in the response data. can do. That is, the "first information" may be all information of the WFD wireless setting WS1 as in the above embodiment, or may be one of the WFD wireless setting WS1 as in the present modification. It may be the information of the department. Similarly, the "sixth information" may be all information in the WFD wireless setting WS1, or may be part of the information in the WFD wireless setting WS1.

(Modification 2) As in Modification 1, the “second information” may be all the information in the normal Wi-Fi wireless setting WS2 (see case C in FIG. 7), or the normal Wi-Fi It may be part of the information in the -Fi wireless setting WS2. 7, the MFP 10 and the mobile terminal 50 belong to the same normal Wi-Fi NW, so the memory 74 of the mobile terminal 50 already stores the normal Wi-Fi wireless settings. Therefore, instead of transmitting the normal Wi-Fi wireless setting WS2, the second information transmitting unit 42 transmits continued use information indicating continuous use of the wireless network to which the mobile terminal 50 belongs to the mobile terminal 50. may be sent to In this modified example, the continued use information is an example of the "second information". Similarly, the "fifth information" may be all information in the normal Wi-Fi wireless setting WS2, or may be part of the normal Wi-Fi wireless setting WS2. However, it may be continued use information.

(Modification 3) As in Modification 1, the “third information” may be all information in the WFD wireless setting WS3 (see cases C and D in FIGS. 7 and 8), It may be part of the information in the WFD wireless setting WS3. Similarly, the "sixth information" may be all information in the WFD wireless setting WS3, or may be part of the information in the WFD wireless setting WS3.

(Modification 4) As in Modification 1, the “fourth information” may be all information in the normal Wi-Fi wireless setting WS4 (see case A in FIG. 5), or the normal Wi-Fi It may be part of the information in the -Fi wireless setting WS4. Further, as in the second modification, the first information transmitting unit 41 may transmit continued use information to the mobile terminal 50 instead of transmitting the normal Wi-Fi wireless setting WS4. In this modified example, the continued use information is an example of the "fourth information". Similarly, the "fifth information" may be all information in the normal Wi-Fi wireless setting WS4, or may be part of the normal Wi-Fi wireless setting WS4. However, it may be continued use information.
