Description

  The present invention relates to a wireless communication system, a connection mediating apparatus, a connection mediating method, and a program.

  In near field type wireless communication such as NFC (Near Field Communication), when transmitting and receiving large capacity data between terminals, only pairing and authentication between terminals are performed by NFC, and actual communication is performed at higher speed. There is a method of taking over to a wireless LAN, Bluetooth (registered trademark) or the like which is a long distance wireless communication. Such an approach is called handover.

  For example, Patent Document 1 discloses a method of establishing a high-speed communication path such as Wi-Fi (Wireless Fidelity) by simply bringing two devices close by handover using NFC.

  However, the conventional handover needs to have an NFC-R / W (reader writer) function in which one terminal can read and write data by specifying a memory area (for example, an address). Therefore, the handover can not be used between the terminals having only the NFC-TAG (NFC tag) function. In addition, even when one of the terminals has the NFC-R / W function, the handover can not be used when it is difficult to physically bring the two terminals close to each other. Furthermore, conventional handover is not suitable for establishing a wireless communication connection between three or more terminals.

  The present invention is intended to solve the problems as described above, and provides a wireless communication system, a connection mediating apparatus, a connection mediating method, and a program capable of easily establishing a wireless connection between terminals. To aim.

(Embodiment 1)
The wireless communication system according to the first embodiment is configured as shown in FIG. The wireless communication system 1 includes a first wireless terminal 100a, a second wireless terminal 100b, a third wireless terminal 100c, and a connection mediation device 200.

  In the wireless communication system 1, the first wireless terminal 100a, the second wireless terminal 100b, and the third wireless terminal 100c communicate with each other through wireless communication of the first scheme. Specifically, these three wireless terminals 100a, 100b and 100c are three printing devices installed in the same facility. The three wireless terminals 100a, 100b, and 100c transmit various types of data through the short distance type wireless communication by a wireless LAN (Local Area Network) such as Wi-Fi (Wireless Fidelity) as the first type wireless communication. Send and receive.

  The connection mediation device 200 is a portable terminal device such as a smartphone. The connection mediating apparatus 200 communicates with each of the three wireless terminals 100a, 100b, and 100c via the second type wireless communication. The connection mediation device 200 uses the three wireless terminals 100a and 100b as the second type of wireless communication, specifically, via near field wireless communication (contactless wireless communication) by NFC (Near Field Communication). , 100c, respectively. Then, as described in detail later, the connection mediation device 200 establishes the establishment of the first type of wireless communication between the three wireless terminals 100a, 100b, and 100c which are not connected by the first type of wireless communication. To mediate.

  The first wireless terminal 100a, the second wireless terminal 100b, and the third wireless terminal 100c have the same configuration and function as one another. Therefore, hereinafter, when the three wireless terminals 100a, 100b, and 100c are referred to without particular distinction, they are referred to as the wireless terminal 100.

  The wireless terminal 100 (ie, each of the three wireless terminals 100a, 100b, and 100c) is configured as shown in FIG. The wireless terminal 100 includes a central processing unit (CPU) 110, a memory 111, an NFC communication unit 121, an NFC antenna 122, a wireless control unit 130, a wireless communication unit 131, and a wireless antenna 132. The wireless terminal 100 also includes a print control unit 150 and a print unit 151, and functions as a printing apparatus that prints a pattern according to print data on a print medium.

  The CPU 110 is connected to each unit of the wireless terminal 100 via a system bus, which is a transmission path for transferring commands and data, and controls the entire wireless terminal 100.

  The memory 111 includes, for example, a random access memory (RAM) functioning as a work memory of the CPU 110, and a non-volatile memory such as a read only memory (ROM) or a flash memory. The memory 111 stores various programs and data used by the CPU 110 to perform various processes, and various data generated or acquired by the CPU 110 performing various processes.

  Further, although not shown, the wireless terminal 100 includes an input unit that receives an operation input from a user, and a display unit that displays various images. The CPU 110 stores various data input through the input unit in the memory 111, and displays and outputs various data stored in the memory 111 through the display unit.

  The NFC communication unit 121 performs NFC communication with the connection mediation device 200 via the NFC antenna 122. NFC is near field wireless communication in which a communication area is narrower than a communication area such as a wireless LAN. The communication area of NFC is limited to an extremely short range of several centimeters to several tens of centimeters.

  Specifically, the NFC communication unit 121 includes an NFC-TAG (NFC tag) read by the connection mediation device 200 having an NFC-R / W (reader / writer) function. The NFC tag is a tag incorporating an IC (Integrated Circuit) chip to which data is read and written by a reader / writer. This IC chip mounts a coil through which an induced current flows by a magnetic field generated between itself and a reader / writer, and data is updated by the induced current flowing through the coil. For example, when the connection mediation device 200 having a reader / writer function approaches the wireless terminal 100 to a close distance which is a communication area of NFC, the data stored in the NFC tag is read and written.

  The three wireless terminals 100a, 100b, and 100c do not have the NFC-R / W function in the NFC communication unit 121, unlike the connection mediation device 200. Therefore, data can not be read from or written to the NFC tag of another wireless terminal 100 via NFC communication.

  The wireless communication unit 131 wirelessly communicates with another wireless terminal 100 via the wireless antenna 132. Specifically, the wireless communication unit 131 communicates with another wireless terminal 100 via near field wireless communication by wireless LAN. The wireless control unit 130 controls such wireless communication in the wireless communication unit 131 under the control of the CPU 110. The wireless communication unit 131 of the first wireless terminal 100a functions as a first wireless communication unit, and the wireless communication unit 131 of the second wireless terminal 100b functions as a second wireless communication unit, and a third wireless terminal The wireless communication unit 131 of the terminal 100c functions as a first wireless communication unit.

  More specifically, the wireless communication unit 131 performs processing such as serial / parallel conversion on the transmission data supplied from the CPU 110, and transmits the transmission data to the other wireless terminal 100 as a communication destination from the wireless antenna 132. Send to In addition, when the wireless communication unit 131 receives data transmitted from another wireless terminal 100 via the wireless antenna 132, the wireless communication unit 131 executes processing such as serial / parallel conversion on the received data, and receives the received data as the CPU 110. Supply to

  Each of the three wireless terminals 100a, 100b, and 100c can communicate with the wireless LAN in both the AP (access point) mode and the client mode. The wireless terminal 100 in the AP mode plays a role of relaying wireless communication between the wireless terminals 100 and connecting to a wired network or another connection device.

  In each wireless terminal 100, a common SSID (Service Set Identifier) is set in order to avoid interference with another type of wireless communication. The SSID is an identifier of the AP in the wireless LAN. Each wireless terminal 100 communicates only with a terminal whose SSID matches, and wireless terminal 100 in the AP mode relays only the communication between wireless terminals 100 in which the same SSID as that of its own device is set.

  The printing unit 151 is a printing mechanism that executes printing processing according to print data received via the wireless communication unit 131, for example. Specifically, the printing unit 151 includes an image forming unit that forms a toner image, a transport unit that transports the print medium by a transport roller, and a fixing device that thermally fixes the toner image on the print medium. The print control unit 150 controls such a printing unit 151 under the control of the CPU 110.

  As described above, each of the three wireless terminals 100a, 100b, and 100c is a terminal provided with an NFC tag, and is not a terminal provided with an NFC reader / writer function. However, since the NFC handover is performed using P2P (Peer to Peer) communication between terminals, that is, communication using a method in which a plurality of terminals are directly connected to transmit / receive data, either of The terminal needs to have a reader / writer function. Therefore, wireless LAN handover can not be performed among the three wireless terminals 100a, 100b, and 100c. Therefore, in the wireless communication system 1, the connection mediation device 200 mediates the handover between the three wireless terminals 100a, 100b, and 100c, that is, the establishment of the connection by the wireless LAN.

  The connection mediating device 200 is configured as shown in FIG. The connection mediation device 200 includes a CPU 210, a memory 211, an input unit 212, a display unit 213, an NFC communication unit 221, an NFC antenna 222, a connection information acquisition unit 225, and a connection information transmission unit 226. .

  The CPU 210 is connected to each unit of the connection mediation device 200 via a system bus, which is a transmission path for transferring an instruction or data, and controls the entire connection mediation device 200.

  The memory 211 includes, for example, a RAM functioning as a work memory of the CPU 210, and a non-volatile memory such as a ROM or a flash memory. The memory 211 stores various programs and data used by the CPU 210 to perform various processes, and various data generated or acquired by the CPU 210 performing various processes.

  The input unit 212 includes, for example, input means such as various buttons and a touch panel. The input unit 212 receives various operation instructions input from the user, and transmits the received operation instructions to the CPU 210.

  The display unit 213 includes display means such as a liquid crystal display, for example. The display unit 213 acquires various types of information, such as the state of NFC communication with the wireless terminal 100, from the CPU 210, and displays an image indicating the acquired information.

  The NFC communication unit 221 performs NFC communication with the wireless terminal 100 via the NFC antenna 222. Specifically, the NFC communication unit 221 has a reader / writer function capable of reading and writing data from and to an NFC tag. Specifically, the NFC communication unit 221 generates a magnetic field around the connection mediation device 200, and generates an induced current in an IC chip incorporated in an NFC tag close to the NFC communication area. Thereby, data can be read and written on the NFC tag. For example, data stored in the NFC tag of the wireless terminal 100 can be acquired or data can be newly written to the NFC tag only by the user bringing the connection mediation device 200 close to the wireless terminal 100 and “holding over”. .

  Under the control of the CPU 210, the connection information acquisition unit 225 uses connection information for connecting the three wireless terminals 100a, 100b, and 100c to each other via the wireless LAN, which is wireless communication of the first method, in the second method. It acquires from the wireless terminal 100 that should function as an AP among the three wireless terminals 100a, 100b, 100c via NFC communication that is wireless communication. The connection information acquisition unit 225 functions as a connection information acquisition unit.

  The connection information is a profile in which information necessary for the other wireless terminal 100 to function as a client to connect to the wireless terminal 100 to function as an AP via a wireless LAN is defined. Specifically, the connection information is information such as a wireless mode (AP mode or client mode) in the wireless LAN, an SSID that is an identifier of the AP, a security method used in the wireless LAN, and an encryption key.

  For example, as shown in FIG. 4A, when the first wireless terminal 100a is designated as an AP in a state where a communication network by wireless LANs among three wireless terminals 100a, 100b, 100c is not established, the user As shown in FIG. 4B, the connection mediation device 200 is brought close to the first wireless terminal 100a into an area where NFC communication can be performed with the first wireless terminal 100a. As described above, when the connection mediation device 200 approaches the first wireless terminal 100 a within the NFC communication area, the connection information acquisition unit 225 performs the first wireless communication via the NFC communication by the NFC communication unit 221. Connection information is acquired from the terminal 100a.

  Under the control of the CPU 210, the connection information transmission unit 226 transmits the connection information acquired by the connection information acquisition unit 225 to the three wireless terminals 100a, 100b, and 100c via the NFC communication that is the second type of wireless communication. Out of the radio terminal 100 that should function as a client. Thereby, the connection information transmission unit 226 causes the three wireless terminals 100a, 100b, and 100c to communicate via the wireless LAN that is the wireless communication of the first scheme. The connection information transmission unit 226 functions as a connection information transmission unit.

  For example, when designating the first wireless terminal 100a as an AP and designating the second wireless terminal 100b as a client, as shown in FIG. 5A, the user transmits the connection mediation device 200 as a second wireless terminal. The second wireless terminal 100b is brought close to the area where NFC communication can be performed with the terminal 100b. When the connection mediation device 200 approaches the second wireless terminal 100b, the connection information transmission unit 226 acquires the second wireless terminal 100b from the first wireless terminal 100a via the NFC communication by the NFC communication unit 221. Send connection information.

  The second wireless terminal 100 b receives the connection information transmitted by the connection information transmission unit 226. In the second wireless terminal 100b, under the control of the CPU 110, the NFC communication unit 121 receives the connection information for receiving the connection information transmitted from the connection mediation device 200 via the NFC communication that is the second type of wireless communication. Act as a means.

  When the second wireless terminal 100b receives the connection information, the wireless control unit 130 functions as a second wireless communication unit, and based on the received connection information, via the wireless LAN that is the first type wireless communication. The connection with the first wireless terminal 100a is established, and communication is performed with the first wireless terminal 100a via the wireless LAN. Specifically, the wireless control unit 130 sets the own device to the client mode according to the wireless mode included in the received connection information, and identifies the first wireless terminal 100a as the AP by the SSID. Then, the wireless control unit 130 performs pairing (mutual authentication) with the first wireless terminal 100 a based on the security method and the encryption key similarly acquired as connection information, and establishes wireless connection by the wireless LAN. . As a result, as shown in FIG. 5B, a wireless LAN communication network is established in which the first wireless terminal 100a and the second wireless terminal 100b function as an AP and a client, respectively.

  When the third wireless terminal 100c is specified as a client in addition to the second wireless terminal 100b, the connection information transmission unit 226 transmits the connection information to the third wireless terminal 100c as well as the second wireless terminal 100b. Do. That is, as shown in FIG. 6A, the user brings the connection mediation device 200 closer to the third wireless terminal 100c into an area where NFC communication can be performed with the third wireless terminal 100c. As described above, when the connection mediation device 200 approaches the third wireless terminal 100 c within the communication area of NFC, the connection information transmission unit 226 performs the third wireless communication via the NFC communication by the NFC communication unit 221. The connection information acquired from the first wireless terminal 100a is transmitted to the terminal 100c.

  In the third wireless terminal 100c, the NFC communication unit 121 receives the connection information transmitted from the connection mediation device 200 via NFC communication. When the connection information is received, the wireless control unit 130 sets the own device to the client mode according to the wireless mode of the received connection information, and identifies the first wireless terminal 100a as the AP by the SSID. Then, the wireless control unit 130 performs pairing (mutual authentication) with the first wireless terminal 100 a based on the security method and the encryption key similarly acquired as connection information, and establishes wireless connection by the wireless LAN. . As a result, as shown in FIG. 6B, a communication network by a wireless LAN is established in which the first wireless terminal 100a functions as an AP and the second wireless terminal 100b and the third wireless terminal 100c function as clients. Be done.

  The flow of connection establishment processing executed in the wireless communication system 1 as described above will be described with reference to the flowcharts shown in FIGS. 7 and 8. In the following, in order to facilitate understanding, the first wireless terminal 100a functions as an AP, and the second wireless terminal 100b and the third wireless terminal 100c serve as clients, as in FIGS. 4 to 6 described above. The case of functioning will be described as an example.

  Before the connection establishment process shown in the flowchart of FIG. 7 is started, as shown in FIG. 4A, in the wireless communication system 1, a communication network by a wireless LAN between three wireless terminals 100a, 100b and 100c is constructed. Not in the state. In such a state, for example, when a user activates a predetermined application for performing a handover of a wireless LAN between three wireless terminals 100a, 100b, and 100c via the input unit 212 (step S11), The connection establishment process shown in the flowchart of FIG. 7 starts.

  When the application is activated in the connection mediation device 200, the CPU 210 instructs the AP (master device) to approach the terminal to be designated (step S12). For example, the CPU 210 displays, on the display unit 213, an instruction message such as "Please move close to the terminal to be AP." When designating the first wireless terminal 100a as an AP, the user who confirms the instruction message brings the connection mediation device 200 closer to the NFC antenna 122 of the first wireless terminal 100a.

  When instructing the AP to approach the terminal to be processed, the CPU 210 determines whether the proximity of the terminal has been detected (step S13). That is, the CPU 210 generates a magnetic field around the connection mediation device 200 by the reader / writer function of the NFC communication unit 221, and shifts the state of the connection mediation device 200 to a state in which the NFC tag can be detected. Then, detection of an NFC tag is awaited by any wireless terminal 100 loaded with the NFC tag approaching to a close distance which is a communication area of NFC.

  When the proximity of the terminal is not detected (step S13; NO), the process remains at step S13, and the CPU 210 stands by until the proximity of the terminal is detected.

  On the other hand, when the connection mediation device 200 is brought close to the NFC antenna 122 of the first wireless terminal 100a by the user, the CPU 210 detects the proximity of the first wireless terminal 100a (step S13; YES). In this case, the CPU 210 uses this detection as a trigger to transmit an AP (access point) activation instruction via NFC communication to the first wireless terminal 100a that has detected proximity (step S14). Thus, the connection mediation device 200 instructs the first wireless terminal 100a to start up in the AP mode of the wireless LAN.

  When the connection mediation device 200 transmits an AP activation instruction to the first wireless terminal 100a, in the first wireless terminal 100a, the CPU 110 receives the AP activation instruction via NFC communication (step S15). That is, by the NFC reader / writer function of the connection mediation device 200, an instruction to be activated in the AP mode of the wireless LAN is written to the NFC tag of the first wireless terminal 100a.

  In the first wireless terminal 100a, when the AP activation instruction is received, the CPU 110, according to the received AP activation instruction, transmits connection information for connecting another wireless terminal 100 to the first wireless terminal 100a via the wireless LAN. It generates (step S16). That is, the CPU 110 sets a profile in which information such as a wireless mode indicating that the own device is an AP, an SSID for identifying the AP, a security method used in a wireless LAN, and an encryption key is defined as connection information. Generate The CPU 110 writes the generated connection information in the NFC tag mounted on the own device.

  When the connection information is generated in the first wireless terminal 100a, in the connection mediation device 200, the connection information acquisition unit 225 acquires connection information generated via NFC communication (step S17). Then, the CPU 210 stores the acquired connection information in the memory 211 (step S18). Specifically, as shown in FIG. 4B, when the connection mediation device 200 approaches the first wireless terminal 100a, the connection information acquisition unit 225 writes the NFC tag of the first wireless terminal 100a. The connection information is acquired by reading the obtained connection information by the function of the NFC reader / writer.

  In the first wireless terminal 100a, when connection information is acquired by the connection mediation device 200, the wireless control unit 130 sets the wireless mode of the own device to AP (step S19). Then, the wireless control unit 130 waits for a connection request from the client (step S20). This is the end of the description of the flowchart shown in FIG. 7, and the description of the flowchart shown in FIG. 8 will be made.

  In the flowchart of FIG. 8, when the connection mediation device 200 acquires connection information, the CPU 210 instructs the client (child device) to approach the terminal to be connected (step S21). For example, the CPU 210 displays on the display unit 213 an instruction message such as “Please move close to a terminal that should be made to the client”. When designating the second wireless terminal 100b as a client, the user who confirms the instruction message brings the connection mediation device 200 close to the NFC antenna 122 of the second wireless terminal 100b.

  When instructing the client to approach to the terminal, the CPU 210 determines whether the proximity of the terminal has been detected (step S22). That is, the CPU 210 generates a magnetic field around the connection mediation device 200 by the reader / writer function of the NFC communication unit 221, and shifts the state of the connection mediation device 200 to a state in which the NFC tag can be detected. Then, detection of an NFC tag is awaited by any wireless terminal 100 loaded with the NFC tag approaching to a close distance which is a communication area of NFC.

  When the proximity of the terminal is not detected (step S22; NO), the process remains at step S22, and the CPU 210 stands by until the proximity of the terminal is detected.

  On the other hand, as shown in FIG. 5A, when the connection mediation device 200 is brought close to the NFC antenna 122 of the second wireless terminal 100b by the user, the CPU 210 detects the proximity of the second wireless terminal 100b. (Step S22; YES). In this case, the CPU 210 uses this detection as a trigger to transmit connection information and a client activation instruction to the second wireless terminal 100b that has detected proximity via NFC communication (step S23). Thereby, the connection mediating apparatus 200 transmits the connection information acquired from the first wireless terminal 100a to the second wireless terminal 100b and instructs the second wireless terminal 100b to start up in the client mode of the wireless LAN. Do.

  When the connection mediation device 200 transmits the connection information and the client activation instruction to the second wireless terminal 100b, the CPU 110 of the second wireless terminal 100b receives the connection information and the client activation instruction via NFC (step S24). ). That is, by the NFC reader / writer function of the connection mediation device 200, an instruction to be activated in the client mode of the wireless LAN is written in the NFC tag of the second wireless terminal 100b.

  In the second wireless terminal 100b, when the connection information and the client activation instruction are received, the CPU 110 expands the received connection information in the memory 111 (step S25). As a result of expanding the connection information in the memory 111, in the second wireless terminal 100b, the first wireless terminal 100a is an AP, and information such as the SSID of that AP, the security method used in the wireless LAN, and the encryption key It can be acquired.

  When the connection information is expanded in the memory 111, the wireless control unit 130 sets the wireless mode of the own device to the client according to the received client activation instruction (step S26). Then, based on the acquired security method and encryption key, the wireless control unit 130 transmits a wireless LAN connection request to the first wireless terminal 100a, which is an AP identified by the SSID, via the wireless LAN. (Step S27). Thereby, pairing (mutual authentication) is performed with the first wireless terminal 100a.

  In the first wireless terminal 100a, the CPU 110 receives the wireless LAN connection request transmitted from the second wireless terminal 100b (step S28). When the received request for connection of the wireless LAN is an appropriate request, the CPU 110 ACKs (acknowledgement) the second wireless terminal 100b that is the request source via the wireless LAN as a response to the connection request for the wireless LAN. Is sent (step S29).

  When the ACK transmitted from the first wireless terminal 100a is normally received in the second wireless terminal 100b (step S30), as shown in FIG. 5 (b), the first wireless terminal 100a and the first wireless terminal 100b are not A wireless LAN connection is established between the two wireless terminals 100b. Thus, the connection establishment process illustrated in the flowchart of FIG. 8 ends.

  When the third wireless terminal 100c is specified as a client in addition to the second wireless terminal 100b, the connection mediating apparatus 200 is also configured for the third wireless terminal 100c as shown in FIG. Send connection information and client activation instruction. That is, the same processing as the processing performed for the second wireless terminal 100b is also performed for the third wireless terminal 100c. As a result, as shown in FIG. 6B, a communication network by a wireless LAN in which the first wireless terminal 100a functions as an AP and the second wireless terminal 100b and the third wireless terminal 100c function as clients is obtained. Be built. The process of establishing the connection by the wireless LAN of the third wireless terminal 100c corresponds to the process of replacing the second wireless terminal 100b with the third wireless terminal 100c in the flowchart shown in FIG. Therefore, the description with reference to the flowchart is omitted. In addition, after establishing connection between three wireless terminals 100 via a wireless LAN, for example, data (a large amount of image data, a firmware program, etc.) stored in the memory 111 of the wireless terminal 100a can be It becomes possible to copy to the memory 111 of the other wireless terminals 100b and 100c.

  As described above, in the wireless communication system 1 according to the first embodiment, the connection mediation device 200 having the NFC reader / writer function is required for connection in the wireless LAN from the wireless terminal 100 functioning as an AP in the wireless LAN. The connection information for which the information is defined is acquired, and the acquired connection information is transmitted to the wireless terminal 100 functioning as a client. Thus, the connection mediating apparatus 200 mediates a handover for the three wireless terminals 100a, 100b, and 100c to communicate with each other on the wireless LAN.

  As a result, terminals having only NFC tags, that is, terminals having no function of reading and writing information by NFC communication, can easily construct a communication network using a wireless LAN. Further, even if there are a plurality of wireless terminals 100 functioning as clients, handover can be performed only by bringing the connection mediation device 200 close to each of the plurality of wireless terminals 100. Even if there is, it can be easily implemented.

Second Embodiment
Next, a second embodiment of the present invention will be described.

  The first embodiment has been described on the premise that the wireless terminal 100 functioning as a client can cope with various settings acquired as connection information from the wireless terminal 100 functioning as an AP. However, if the specifications (connection method) of wireless communication such as wireless standards and security methods that can be supported differ among a plurality of wireless terminals 100, the setting acquired as connection information from the wireless terminal 100 functioning as an AP functions as a client In some cases, the wireless terminal 100 can not cope. For example, when the wireless terminal 100 functioning as a client does not correspond to the security method acquired as one of connection information from the wireless terminal 100 functioning as an AP, wireless connection can not be established. Therefore, the wireless communication system 1 according to the second embodiment performs processing so that wireless connection can be established even when the connection methods of wireless communication are different between the plurality of wireless terminals 100. This will be described below.

  FIGS. 9A to 9C show examples of connection methods that can be handled by each of the three wireless terminals 100a, 100b, and 100c. Here, the connection method means an agreement established when a plurality of wireless terminals 100 connect to each other, such as a wireless standard and a security method.

  For example, as shown in FIG. 9A, the first wireless terminal 100a supports the three standards of 802.11a, 802.11g, and 802.11n as the wireless LAN standards, and is open as the security method. It supports four security methods: WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2. That is, the first wireless terminal 100a can wirelessly communicate with the wireless terminal 100 of the communication destination in any of the three wireless standards, and further, using any of the four security schemes Even in this case, wireless communication can be performed with the wireless terminal 100 of the communication destination.

  The first wireless terminal 100a, as the connection information, together with the wireless mode and the SSID, any one wireless standard selected from among the three wireless standards, and any one security scheme selected from the four security schemes, And generating information defining an encryption key of the selected security scheme. The encryption key is not available when the security method is OPEN, for example, "12345wep" when the security method is WEP, for example, "12345wpa" when the security method is WPA, and for example, "1234wpa2" when the security method is WPA2. Is set as The generated connection information is transmitted to the second wireless terminal 100b and the third wireless terminal 100c by the connection mediation device 200.

  If the second wireless terminal 100b can support the same three wireless standards and four security methods as the first wireless terminal 100a, as shown in FIG. 9B, the first wireless terminal 100a and the second wireless terminal 100b may be used. There is no inconsistency in the connection method with the wireless terminal 100b of Therefore, based on the connection information received via the connection mediation device 200, the second wireless terminal 100b can establish a wireless LAN connection with the first wireless terminal 100a without any problem.

  On the other hand, in the third wireless terminal 100c, as shown in FIG. 9C, the third wireless standard is compatible with the same three wireless standards as the first wireless terminal 100a, but the first wireless terminal 100a is also compatible. In the case where only two security schemes (OPEN and WPA) among the four security schemes are available, a mismatch in connection scheme occurs between the first wireless terminal 100a and the third wireless terminal 100c. For example, when connection information specifying WPA2 as a security scheme is transmitted from the first wireless terminal 100a, the third wireless terminal 100c that has received the connection information can communicate with the first wireless terminal 100a in a wireless LAN. I can not establish a connection.

  As a result, as shown in FIG. 10A, for example, connection of a wireless LAN is established between the first wireless terminal 100a (AP) and the second wireless terminal 100b (client). There is a situation where the wireless terminal 100c can not establish a wireless LAN connection with another wireless terminal 100 because the connection methods do not match. As described above, when the connection method determined in the connection information acquired by the connection information acquisition unit 225 is not a connection method that can be supported by the third wireless terminal 100c, the connection mediation device 200 determines that the third wireless terminal 100c is used. The connection method that can be supported by is acquired from the third wireless terminal 100c via NFC communication. At this time, under the control of the CPU 210, the NFC communication unit 221 of the connection mediation device 200 functions as a connection scheme acquisition unit that acquires a connection scheme that can be supported by the third wireless terminal 100c.

  For example, as shown in FIG. 10A, the connection mediating apparatus 200 transmits connection information to the third wireless terminal 100c, so when the third wireless terminal 100c approaches within the communication area of NFC. It is determined whether the connection method defined in the connection information is a connection method that can be supported by the third wireless terminal 100c. As a result of the determination, if the connection method determined in the connection information is not a connection method that can be supported by the third wireless terminal 100c, the connection mediation device 200 determines that the third wireless terminal 100c is connected as shown in FIG. The connection method that can be supported by is acquired from the third wireless terminal 100c via NFC communication.

  When the connection method is acquired, the connection mediating apparatus 200 transmits the acquired connection method to the first wireless terminal 100a functioning as an AP via NFC communication. At this time, under the control of the CPU 210, the NFC communication unit 221 of the connection mediation device 200 functions as a connection scheme transmission unit that transmits the connection scheme acquired from the third wireless terminal 100c to the first wireless terminal 100a.

  Specifically, the connection mediating apparatus 200 displays a message such as "Please bring the connection mediating apparatus 200 closer to the first wireless terminal 100a again because the connection of the third wireless terminal 100c can not be established." By displaying in 213, the user is instructed to place the connection mediation device 200 in proximity to the first wireless terminal 100a functioning as an AP again. When the user who receives this instruction brings the connection mediation device 200 closer to the first wireless terminal 100a into the communication area of NFC, as shown in FIG. Connection information acquired from the third wireless terminal 100c is transmitted to the first wireless terminal 100a.

  The first wireless terminal 100a receives, via NFC communication, a connection method that can be supported by the third wireless terminal 100c, which is transmitted from the connection mediation device 200. At this time, under the control of the CPU 110, the NFC communication unit 121 of the first wireless terminal 100a functions as a connection scheme receiving unit that receives the connection scheme transmitted from the connection mediation device 200. When the connection method is received, the first wireless terminal 100a includes the received connection method so that the second wireless terminal 100b and the third wireless terminal 100c connect to the first wireless terminal 100a via the wireless LAN. Second connection information defining information is newly generated. At this time, the wireless control unit 130 of the first wireless terminal 100 a functions as a connection scheme generation unit that generates the second connection information.

  When the second connection information is generated in the first wireless terminal 100a, the connection mediation device 200 acquires the generated second connection information from the first wireless terminal 100a via NFC communication. That is, the connection information acquisition unit 225 acquires the second connection information generated in the first wireless terminal 100a when the connection mediation device 200 approaches the first wireless terminal 100a to transmit the connection method. Do.

  Upon acquiring the second connection information, the connection mediating apparatus 200 sends the acquired second connection information to the second wireless terminal 100b and the third wireless terminal 100c in the same manner as when the connection information was first acquired. Send. Thereby, the connection of the wireless LAN in the wireless communication system 1 is established based on the second connection information. That is, as shown in FIG. 11A, when the connection mediation device 200 approaches the second wireless terminal 100b within the NFC communication area, the connection information transmission unit 226 generates the second connection information. , And transmits the second connection information to the second wireless terminal 100b via the NFC communication, and the second connection information when the connection mediation device 200 approaches the third wireless terminal 100c within the NFC communication area. To the third wireless terminal 100c.

  In the second wireless terminal 100b and the third wireless terminal 100c, the NFC communication unit 121 functions as a connection information receiving unit under the control of the CPU 110, and receives the second connection information through NFC communication. . Then, the wireless control unit 130 controls the wireless communication unit 131 to establish a connection with the first wireless terminal 100a via the wireless LAN based on the received second connection information. Thereby, as shown in FIG. 11B, the first wireless terminal 100a functions as an AP among the three wireless terminals 100a, 100b, and 100c, and the second wireless terminal 100b and the third wireless terminal A communication network in which 100c functions as a client is established.

  As described above, in the wireless communication system 1 according to the second embodiment, the connection mediation device 200 functions as the client in the connection method in the connection information generated once in the wireless terminal 100 functioning as the AP. If it is found that the wireless terminal 100 can not cope with the connection, the wireless terminal 100 functioning as the client acquires a compatible connection method and transmits the connection method to the wireless terminal 100 functioning as an AP. Then, connection information is newly acquired from the wireless terminal 100 functioning as an AP, and wireless connection is reestablished again between the three wireless terminals 100a, 100b, and 100c according to the acquired connection information. As a result, wireless connection can be established between a plurality of wireless terminals 100 having different connection methods of wireless communication without the user being aware of various settings of the wireless LAN.

(Embodiment 3)
Next, a third embodiment of the present invention will be described.

  In the second embodiment, when it is found that the third wireless terminal 100c can not cope with the connection method defined in the connection information, the first wireless terminal 100a functioning as an AP generates connection information again. That is, the terminal functioning as an AP remains unchanged from the first wireless terminal 100a. On the other hand, in the wireless communication system 1 according to the third embodiment, the wireless terminal 100 which has been found to be incompatible with the connection method defined in the connection information newly functions as an AP. This will be described below.

  Hereinafter, as in the second embodiment, the three wireless terminals 100a, 100b, and 100c can cope with the connection scheme shown in FIGS. 9A to 9C, respectively, as shown in FIG. As shown in FIG. 1, a case where the connection method acquired from the first wireless terminal 100a is not compatible with the third wireless terminal 100c will be described as an example.

  In the third wireless terminal 100c, when the connection method determined in the connection information acquired by the connection information acquisition unit 225 is not a connection method that can be supported by the third wireless terminal 100c, the third wireless terminal 100c is The second connection information defining information for connecting the first wireless terminal 100a and the second wireless terminal 100b to the third wireless terminal 100c via the wireless LAN, including a connection method that can be supported by the own device Generate At this time, the wireless control unit 130 of the third wireless terminal 100 c functions as a second connection information generation unit that generates the second connection information under the control of the CPU 110.

  For example, as shown in FIG. 12A, when the connection mediation device 200 approaches the third wireless terminal 100c within the NFC communication area to transmit connection information, the connection determined by the connection information It is determined whether the method is a connection method that can be supported by the third wireless terminal 100c. As a result of the determination, if the connection method determined in the connection information is not a connection method that can be supported by the third wireless terminal 100c, the connection mediating device 200 performs the third operation to cause the third wireless terminal 100c to function as an AP. It instructs the third wireless terminal 100c to generate the second connection information in a connection scheme that can be supported by the wireless terminal 100c. For example, when the security method defined in the connection information is WPA2 and the third wireless terminal 100c supports WPA but does not support WPA2, the connection mediation device 200 determines that the third wireless terminal 100c is used. In addition, the third wireless terminal 100c is instructed to generate the second connection information according to the security method by the WPA that can be supported by the third wireless terminal 100c.

  When the second connection information is generated in the third wireless terminal 100c, as shown in FIG. 12 (b), the connection mediating device 200 transmits the generated second connection information via the NFC communication. It is acquired from the wireless terminal 100c of 3. That is, the connection information acquisition unit 225 acquires the second connection information generated in the third wireless terminal 100c when the connection mediation device 200 approaches the third wireless terminal 100c to transmit connection information. Do.

  When acquiring the second connection information, the connection mediating apparatus 200 transmits the acquired second connection information to the first wireless terminal 100a and the second wireless terminal 100b. Thereby, the connection of the wireless LAN in the wireless communication system 1 is established based on the second connection information. That is, as shown in FIG. 12B, the connection information transmission unit 226 transmits the second connection information when the connection intermediation device 200 approaches the first wireless terminal 100a to the inside of the communication area of NFC. , And transmits the second connection information to the first wireless terminal 100a via the NFC communication, and the second connection information when the connection mediation device 200 approaches the third wireless terminal 100c within the NFC communication area. To the second wireless terminal 100b.

  In the first wireless terminal 100a and the second wireless terminal 100b, the NFC communication unit 121 functions as a second connection information receiving unit under the control of the CPU 110, and the second connection information is transmitted via the NFC communication. Receive Then, the wireless control unit 130 controls the wireless communication unit 131 to establish a connection with the third wireless terminal 100c via the wireless LAN based on the received second connection information. Thereby, as shown in FIG. 13, the third wireless terminal 100c functions as an AP among the three wireless terminals 100a, 100b, 100c, and the first wireless terminal 100a and the second wireless terminal 100b are clients. A communication network is established that functions as

  As described above, in the wireless communication system 1 according to the third embodiment, the wireless terminal 100 designated as the client can not cope with the connection method in the connection information generated in the wireless terminal 100 designated as the AP first. If this is found, the wireless terminal 100 designated as this client is newly changed to an AP. Then, the connection mediation device 200 acquires, from the wireless terminal 100 that has newly become an AP, second connection information generated by a connection method that can be supported by the wireless terminal 100, and uses the acquired second connection information. Again, wireless connection is reestablished between the three wireless terminals 100a, 100b, 100c. As a result, wireless connection can be easily established between the plurality of wireless terminals 100 having different connection methods of wireless communication in fewer steps than in the second embodiment.

(Embodiment 4)
Next, a fourth embodiment of the present invention will be described.

  In the third embodiment, when the third wireless terminal 100c newly becomes an AP, the first wireless terminal 100a can use a connection method that can be handled by the third wireless terminal 100c generated as the second connection information. Or the situation which the 2nd radio | wireless terminal 100b can not respond also arises. Therefore, in the fourth embodiment, as shown in FIG. 14, the connection mediation device 200 is capable of handling a plurality of connection methods that can be supported in NFC communication from the first wireless terminal 100a and the second wireless terminal 100b. Obtain in advance. Then, by selecting a connection method that can be supported by the third wireless terminal 100c among the acquired plurality of connection methods, the connection method that can be supported by any of the three wireless terminals 100a, 100b, and 100c is selected. The third wireless terminal 100c generates the second connection information.

  Specifically, in the connection mediating apparatus 200, when the connection information acquisition unit 225 acquires connection information from the first wireless terminal 100a via NFC communication, a plurality of the first wireless terminal 100a can cope with the connection information. The connection method is acquired from the first wireless terminal 100a via NFC communication. For example, as shown in FIG. 9A, in the case where the first wireless terminal 100a can support three wireless standards and four security methods, the connection information acquisition unit 225 can use any one connection method. These three wireless standards and four security schemes are acquired as a plurality of connection schemes that can be supported by the first wireless terminal 100a.

  Furthermore, when the connection information acquisition unit 225 transmits connection information to the second wireless terminal 100b via NFC communication, the plurality of connection methods that can be supported by the second wireless terminal 100b are via NFC communication. It acquires from the 2nd radio | wireless terminal 100b. For example, as shown in FIG. 9B, in the case where the second wireless terminal 100b can support the same three wireless standards and four security methods as the first wireless terminal 100a, the connection information acquisition unit The H.225 acquires these three wireless standards and four security schemes.

  Then, when the connection information transmission unit 226 transmits the connection information to the third wireless terminal 100c, if it is found that the third wireless terminal 100c can not cope with the connection method in the transmitted connection information, the connection mediating apparatus In 200, a connection method that can be supported by the third wireless terminal 100c is selected from the plurality of connection methods. For example, when the security method defined in the connection information is WPA 2 and the third wireless terminal 100 c supports WPA but does not support WPA 2, the connection mediation device 200 determines that the first wireless terminal 100 a is the first wireless terminal 100 a. And the second wireless terminal 100b, the WPA that can be supported by the third wireless terminal 100c is selected from the four security schemes of OPEN, WEP, WPA, and WPA2 that can be supported. The connection information transmission unit 226 transmits the selected security scheme to the third wireless terminal 100c via NFC communication.

  In the third wireless terminal 100c, when the NFC communication unit 121 receives the security method selected by the connection mediation device 200, the wireless control unit 130 functions as a connection information generation unit under the control of the CPU 110, and is selected. Connection information defining a connection method is generated as second connection information. As a result, second connection information that defines a connection method that can be supported by any of the three wireless terminals 100a, 100b, and 100c is generated.

  The process after the second connection information is generated is the same as the process in the third embodiment. That is, as shown in FIG. 12B, the connection mediation device 200 acquires the generated second connection information from the third wireless terminal 100c via NFC communication. Upon acquiring the second connection information, the connection mediating apparatus 200 transmits the acquired second connection information to the first wireless terminal 100a and the second wireless terminal 100b, as shown in FIG. 12 (b). . Thereby, the connection of the wireless LAN in the wireless communication system 1 is established based on the second connection information. As a result, as shown in FIG. 13, among the three wireless terminals 100a, 100b, 100c, the third wireless terminal 100c functions as an AP, and the first wireless terminal 100a and the second wireless terminal 100b are clients. A communication network is established that functions as

  As described above, in the wireless communication system 1 according to the fourth embodiment, each connection terminal 200 communicates with each wireless terminal 100 from each wireless terminal 100 that communicates by NFC, including the wireless terminal 100 initially designated as the AP. In the above, a plurality of connection methods that can be supported are obtained in advance. Then, when there is a wireless terminal 100c that can not cope with the connection method defined in the connection information, the connection mediation device 200 can select a connection method that can correspond to all the wireless terminals 100 among the plurality of acquired connection methods. By selecting, the second connection information that defines the connection method that can be supported between all the wireless terminals 100 is acquired. As a result, wireless connection can be more reliably established between a plurality of wireless terminals 100 having different connection methods of wireless communication.

  In the second, third, and fourth embodiments, since the connection method of the third wireless terminal 100c does not match the connection method defined in the connection information, the third wireless terminal 100c wirelessly connects with another wireless terminal 100. I explained an example that can not be done. However, the terminal to which wireless connection can not be made may be the second wireless terminal 100 b, or may be another wireless terminal 100 when there are four or more wireless terminals 100. Also in the case where the terminal to which wireless connection can not be made is other than the third wireless terminal 100c, the description may be made similarly to the above by replacing the third wireless terminal 100c with the second wireless terminal 100b or another wireless terminal 100. it can.

(Modification)
Although the embodiment of the present invention has been described above, the above embodiment is an example, and the scope of application of the present invention is not limited to this. That is, the embodiment of the present invention can be applied in various ways, and any embodiment is included in the scope of the present invention.

  For example, in the above embodiment, the wireless terminal 100 communicates with another wireless terminal 100 via the wireless LAN as the wireless communication of the first scheme. However, in the present invention, the wireless terminal 100 communicates with another wireless terminal 100 via short-range wireless communication of another standard such as Bluetooth (registered trademark), Zigbee (registered trademark), ad hoc network, etc. May be In this case, the connection mediating apparatus 200 mediates the handover of the wireless communication other than the wireless LAN by the same process as the process described above.

  For example, when each wireless terminal 100 communicates with another wireless terminal 100 via wireless communication by Bluetooth, the connection information acquisition unit 225 in the connection mediation device 200 performs Bluetooth communication from the wireless terminal 100 that should function as a master device. Connection information for connection by each wireless terminal 100 is acquired via NFC communication. Specifically, the connection information is information such as a wireless mode indicating whether the device is a parent device or a child device, and an ID that is an identifier for the child device to uniquely identify the parent device in Bluetooth communication. The connection information transmission unit 226 transmits the acquired connection information of Bluetooth communication to the wireless terminal 100 that should function as a slave via NFC communication. Thereby, the connection information transmission unit 226 causes each wireless terminal 100 to communicate via Bluetooth communication.

  Further, in the above embodiment, the connection mediating device 200 communicates with the wireless terminal 100 via NFC communication as wireless communication of the second scheme. However, in the present invention, the connection mediation device 200 transmits near-field wireless communication of another standard such as FeliCa (registered trademark) or MIFARE (registered trademark) or wireless communication by RFID (Radio Frequency Identifier), for example. It may communicate with the wireless terminal 100.

  Further, in the above embodiment, the printing apparatus has been described as an example of the wireless terminal 100. However, in the present invention, the wireless terminal is not limited to the printing apparatus. The wireless terminal is, for example, a digital camera, a wearable terminal, and the like as long as the wireless terminal is a device capable of establishing a wireless network by a plurality of wireless communication via the first wireless communication and communicating with the connection mediation device via the second wireless communication. It may be a general computer terminal or the like. Further, the connection mediation device is not limited to a portable terminal device such as a smart phone, and may be another type of device as long as it can mediate wireless communication between a plurality of wireless terminals.

  Further, in the above embodiment, all of the three wireless terminals 100a, 100b, and 100c have only the NFC tag function and do not have the NFC reader / writer function. Therefore, although handover by NFC can not be performed only by the wireless terminals 100, handover can be performed by mediation by the connection mediation device 200. However, in the present invention, any or all of the three wireless terminals 100a, 100b, and 100c may have an NFC reader / writer function. That is, even if the wireless terminal 100 has the NFC reader / writer function, the wireless terminals 100 may not be able to be brought close to each other, for example, when the wireless terminal 100 is a physically large device. Even in such a case, the connection mediating apparatus 200 mediates handover as described above, so that the effect that handover can easily be performed can be obtained.

  Further, in the above embodiment, the wireless communication system 1 includes the three wireless terminals 100a, 100b, and 100c. However, in the present invention, the number of wireless terminals 100 is not limited to three, and may be two or four or more. That is, the present invention is applied to establishing a wireless communication connection between a plurality of wireless terminals 100 in which any one wireless terminal 100 functions as an AP and the other one or more wireless terminals 100 function as a client. can do. In the above embodiment, although the case where all the first wireless terminals 100a are specified as APs is described as an example, the case where other wireless terminals 100 are first specified as APs is also described in the same manner as above. it can.

  Further, in the above embodiment, the wireless terminal 100 and the connection mediation device 200 have a CPU. However, in the present invention, the wireless terminal 100 and the connection mediation device 200 may include a dedicated control circuit such as an application specific integrated circuit (ASIC) instead of the CPU, and the control circuit may control the entire device.

  In addition to being able to be provided as a connection mediating device and a wireless terminal provided in advance with the configuration for realizing the function according to the present invention, the application data processing device etc. according to the present invention can be provided by applying a program. It can also function as a wireless terminal. That is, the program for realizing the respective functional configurations of the connection mediation device 200 and the wireless terminal 100 exemplified in the above embodiment is applied by being executed by a CPU or the like that controls an existing information processing device or the like. It can function as a connection mediation device and a wireless terminal according to the invention. Also, the connection mediating method according to the present invention can be implemented using a connection mediating apparatus.

  Moreover, the application method of such a program is arbitrary. For example, the program can be stored in a computer readable storage medium such as a flexible disk, a CD (Compact Disc) -ROM, a DVD (Digital Versatile Disc) -ROM, a memory card, and the like. Furthermore, the program can be superimposed on a carrier wave and applied via a communication medium such as the Internet. For example, the program may be posted and distributed in a bulletin board (BBS: Bulletin Board System) on a communication network. Then, the program may be activated and executed in the same manner as other application programs under the control of an OS (Operating System) to execute the above process.

  Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments, and the present invention includes the invention described in the claims and the equivalents thereof. included.
