Description

  The present invention relates to a wireless connection method, a wireless connection device, and a terminal.

  In recent years, with the development of wireless communication technology, many wireless communication systems have been proposed, and wireless LAN systems using IEEE 802.11, which is one of them, have been remarkably spread in enterprises and general homes. In order to form a wireless network using IEEE 802.11, it is necessary to set an SSID (Service Set ID) for identifying the wireless network. In order to ensure communication security, it is essential to set some kind of authentication and encryption method.

  There are a plurality of authentication and encryption methods. For example, WEP (Wired Equivalent Privacy) defined by IEEE and WPA (Wi-Fi Protected Access) defined by Wi-Fi Alliance, which is a wireless LAN industry group. ) Etc. are used in the market. When WEP or WPA is used, a passphrase must be input and set in each of the access point, which is a parent device constituting the wireless LAN, and the station, which is a child device. To keep security high, it is effective to lengthen the passphrase, but entering a long passphrase with a wireless device that does not have a keyboard is a very cumbersome task and places a burden on the user. .

  For this reason, a technique for simplifying security settings has been devised. For example, in WPS (Wi-Fi Protected Setup) defined by Wi-Fi Alliance, a dedicated button is prepared for the access point and station, and the setting is completed by pressing the button. A method of setting a number by issuing a number and causing the station to input the number is defined.

  An example of a unique security setting method for easily performing security setting is disclosed in Patent Document 1. In this example, the wireless device having the display unit displays the security setting information, and the wireless device having the imaging unit captures the displayed information to acquire the information, so that the user does not input the pass phrase. Can communicate with security.

Japanese Patent No. 4416392

  If WPS or other unique security setting method is used, it is not necessary for the user to input a long passphrase and the burden of security setting can be reduced. However, naturally, all the devices forming the wireless network are WPS or If it does not support other unique security setting methods, that method cannot be used. There are many wireless devices in the market that do not employ WPS or other unique security setting methods, and even one of the wireless devices owned by the user may not be compatible with WPS or other unique security setting methods. For example, a wireless network must be configured using a method such as WEP or WPA, which requires input of a passphrase.

  In addition, the technique disclosed in Patent Document 1 can be used only for a wireless device having a display unit. Since a general access point does not have a display unit, this method cannot be used, and a method such as WEP or WPA, which requires a passphrase to be input at the station, must be used.

  On the other hand, in recent years, devices that do not have a keyboard, such as televisions, are also provided with a function of connecting to a wireless network. However, it is often forced to input a long passphrase for the above reasons, causing a problem in user convenience.

  In view of the above problems, the present invention adds a new device to a wireless network even if a wireless network is configured by a security setting method for setting a passphrase using a normal access point that does not have a display unit. In this case, it is an object to provide a wireless system and a wireless device that perform security setting easily without inputting a passphrase.

  In order to achieve the above object, the configuration described in the claims is adopted.

  According to the present invention, it is possible to easily connect to a wireless network as a station without inputting a passphrase for a wireless network configured with a normal access point and station having no display unit.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same portions are denoted by the same reference numerals.

  FIG. 1 is a configuration example of a wireless system in the present embodiment. 1 is a television, 100 is a television remote control, and 2 is a wireless terminal with a built-in wireless LAN communication device, for example, a mobile phone. Reference numeral 3 denotes an access point which is a base unit of the wireless LAN. The television 1 includes a tuner 11, a display unit 12, a storage unit 13, a control unit 14, a radio unit 15, a remote control reception unit 16, a generation unit 17, and a conversion unit 18. The wireless terminal 2 includes a camera 21, a display unit 22, a storage unit 23, a control unit 24, a wireless unit 25, an input unit 26, a mobile phone communication unit 27, and an analysis / recognition unit 28.

  Authentication information necessary for forming a wireless LAN such as SSID, communication method, authentication method, and encryption method is set in the access point 3, and the same authentication information is set in the wireless unit 15 built in the television 1 By doing so, the access point 3 and the television 1 can form a wireless LAN and perform secure communication. Similarly, by setting the same authentication information as that of the access point 3 in the wireless unit 25 built in the wireless terminal 2, the access point 3 and the wireless terminal 2 can form a wireless LAN and perform secure communication.

  When receiving a general broadcast, the television 1 receives a broadcast signal transmitted from a transmission station by the tuner 11 and converts it into a video signal to display on the display unit 12. When the user gives an instruction such as channel switching, the remote control receiving unit 16 receives a signal transmitted from the remote control 100, the control unit 14 recognizes the instruction included in the received signal, and controls the tuner 11 and the display unit 12. I do.

  The wireless unit 15 can operate as either an access point that is a parent device of a wireless LAN or a station that is a child device in accordance with an instruction from the control unit 14. When the wireless unit 15 operates as a station, the generation unit 17 generates the same authentication information as the authentication information such as the SSID, communication method, authentication method, and encryption method set in the access point 3 according to the instruction of the control unit 14, By setting the wireless unit 15, communication with the access point 3 can be performed. When the wireless unit 15 is operated as an access point, the generation unit 17 can freely set authentication information such as an SSID, an authentication method, and an encryption method. The conversion unit 18 can convert the authentication information into video information such as a barcode and display it on the display unit 12. The storage unit 13 stores the generated authentication information according to an instruction from the control unit 14.

  The wireless terminal 2 can display the video captured by the camera 21 on the display unit 22. If the captured video is video information converted from numerical values or text information such as a barcode, the analysis / recognition unit 28 acquires the captured video from the camera 21 and analyzes the video to include the captured video. Can recognize numeric or character information. The input unit 26 receives an input of authentication information from the user, and the control unit 24 can communicate with the access point 3 by setting the input authentication information in the wireless unit 25. The radio unit 25 according to the present embodiment operates only as a station, but even if it can operate as an access point, there is no influence on the operation of the present embodiment.

  Further, the wireless terminal 2 includes a mobile phone communication unit 27 that operates based on a wireless communication standard different from the wireless unit 25, for example, the mobile phone standard, and can perform wireless communication independently of the wireless unit 25.

  Further, when the connection with the access point 3 is successful, the control unit 24 stores the authentication information in the storage unit 23. Alternatively, the input unit 26 may accept input of authentication information from the user, and the input authentication information may be stored in the storage unit 23. When there are a plurality of access points that have been successfully connected, or when there are a plurality of authentication information input by the user, all the authentication information is stored in the storage unit 23.

  FIG. 7 shows an example of authentication information stored in the storage unit 23. In this example, four access points are stored, and an SSID, a wireless method, an authentication method, an encryption method, and a passphrase are stored as a table. For example, no. The access point 1 has an SSID of AP1, and the wireless system corresponds to IEEE802.11b and IEEE802.11g. The authentication method is WPA, the encryption method is TKIP (Temporal Key Integrity Protocol), and the passphrase is 12345789. No. The access point Test No. 2 indicates that an authentication method, an encryption method, and a passphrase are not set, and is an access point that can be freely connected to any station. No. 3 and no. Similarly, the SSID, the wireless method, the authentication method, the encryption method, and the passphrase are stored in the access point 4.

  In this example, No. The operation when the access point stored in 3 and whose SSID is MyHome is the access point 3 in FIG. 1 will be described. The information stored in the storage unit 23 is not limited to this, and other information such as a MAC address and an IP address may be stored together.

  Here, FIG. 2 shows a configuration state of the wireless LAN as a premise. In FIG. 2, reference numerals 201 and 202 denote wireless devices operating as stations that are slave units of the wireless LAN, the wireless terminal 2, and the access point 3 are the same as those shown in FIG. The access point 3, the wireless devices 201 and 202, and the wireless terminal 2 are already set with the same authentication information, and can configure a wireless LAN and perform secure communication. On the other hand, authentication information is not set in the television 1 and communication with the access point 3 is not possible. Further, the access point is connected to the external network 4, and the wireless devices 201 and 202 and the wireless terminal 2 can be connected to the external network 4 via the access point 3.

  An object of the present invention is to add the television 1 to the wireless LAN and finally configure the wireless LAN shown in FIG. 4 with a simple operation. In the state of FIG. 4, the same authentication information is set in the television 1, and the wireless terminal 2, the wireless devices 201 and 202, and the access point 3 constitute a wireless LAN. Communication can be performed. Needless to say, the television 1, the wireless terminal 2, and the wireless devices 201 and 202 can be connected to the external network 4.

  Next, operations of the television 1 and the wireless terminal 2 will be described with reference to the flowchart shown in FIG. As shown in the preconditions shown in FIG. 2 above, the TV 1 has not been set with authentication information for connection to the access point 3, while the wireless terminal 2 has already been set with authentication information and communicated with the access point 3. Is established.

  First, in step 101, the user instructs to establish a wireless LAN connection. Specifically, the remote control receiving unit 16 receives a signal transmitted from the remote control 100, the control unit 14 recognizes an instruction included in the received signal, and activates the wireless unit 15 to operate as an access point. Subsequently, in step 102, the control unit 14 issues an instruction to the generation unit 17, and the generation unit 17 determines the SSID, communication method, authentication method, and encryption method used by the wireless unit 15. Further, a passphrase used for authentication is generated, and the determined / generated authentication information is set in the wireless unit 15. It is not always necessary for the generation unit 17 to automatically generate the authentication information. The user may input arbitrary authentication information using the remote controller 100, and the remote control reception unit 16 may receive the authentication information.

  In step 103, the conversion unit 18 converts the generated authentication information into video information such as a barcode. The form of the video information is not limited to the barcode, and any form may be used as long as the authentication information can be recognized from the video information captured by the terminal 2. Subsequently, in step 104, the converted video information is displayed on the display unit 12, and the television 1 waits for a connection request from the wireless terminal 2.

  Now, the operation of the wireless terminal 2 will be described. In step 201, the user instructs to connect the television 1 and the wireless terminal 2 via a wireless LAN. Specifically, the input unit 26 receives an input from the user, and the control unit 24 activates the camera 21 to a photographing ready state.

  When steps up to step 104 are executed on the television 1, video information such as a barcode is displayed on the display unit 12, so the wireless terminal 2 captures the displayed video information with the camera 21 in step 202. Next, in step 203, the analysis / recognition unit 28 acquires video information from the camera 21, analyzes the acquired video, and performs authentication information included therein, for example, SSID, communication method, authentication method, encryption method, and authentication. The passphrase to be used is recognized and notified to the control unit 24. Subsequently, in step 204, the control unit 24 sets the recognized authentication information in the wireless unit 25, and the wireless unit 25 makes a connection request to the wireless unit 15 of the television 1 using the set authentication information.

  Here, returning to the operation of the television 1, in step 105, the wireless unit 15 receives a connection request from the wireless terminal 2, and the control unit 14 sets the authentication information transmitted from the wireless unit 25 in the wireless unit 15. It is determined whether or not it matches the authentication information. The authentication information transmitted by the wireless unit 25 is information transmitted to the wireless terminal 2 by using the authentication information set in the wireless unit 15 by using video information such as a barcode. Matches. Therefore, the control unit 14 causes the wireless unit 15 to transmit connection permission to the wireless unit 25. With the above operation, the television 1 and the wireless terminal 2 constitute a wireless LAN that performs secure communication. If the connection is established, the display of the video information on the display unit 12 may be stopped.

  The state of the wireless LAN at this time is shown in FIG. Since the wireless unit 15 of the television 1 is activated as an access point, and the wireless terminal 2 is connected to the television 1 using authentication information acquired from the television 1 as a station, it is independent from the wireless LAN of the access point 3. Configured network.

  Next, in step 205, the control unit 24 of the wireless terminal 2 reads authentication information of all access points stored from the storage unit 23. In step 206, a list of access points is displayed on the display unit 22 based on the read information. FIG. 8 shows an example in which the information shown in FIG. 7 is read from the storage unit 23 and displayed on the display unit 22. Only the SSIDs of the four access points that have been connected in the past or that the user has input in the past are displayed, and the user is prompted to select an access point to be connected. In step 207, the input unit 26 receives an access point selection input from the user. In this embodiment, the user wants to connect to the access point 3 in FIG. 3, the access point whose SSID is MyHome is selected. Since the SSID of the access point 3 is set when the user constructs the wireless LAN shown in FIG. 2, the SSID to be connected can be selected.

  In addition, although the authentication information of the access point that has been connected in the past is stored in the storage unit 23, it is not always necessary to store the authentication information when connected to the television 1 in the operation of this embodiment. That is, even if the wireless terminal 2 transmits a connection request to the television 1 in step 204 and receives a connection permission to establish a connection, the authentication information set in the wireless unit 25 at this time is stored in the storage unit 23. There is no need.

  Next, in step 208, the authentication information of the selected access point is transmitted from the wireless unit 25 to the wireless unit 15. In this embodiment, the user is no. 3, the SSID is MyHome, the wireless method is IEEE802.11a, 11b, 11g, or 11n, the authentication method is WPA, the encryption method is AES, and the passphrase is sec2 #. Authentication information such as 34 is transmitted to the wireless unit 15.

  In step 106, the television 1 acquires the authentication information received by the wireless unit 15 by the control unit 14, stores the received authentication information in the storage unit 13, and sends a reception notification of authentication information from the wireless unit 15 to the wireless unit 25. Send to.

  Further, in the television 1, in step 107, the control unit 14 restarts the wireless unit 15 as a wireless LAN station. Next, in step 108, the control unit 14 sets the acquired access point authentication information for the wireless unit 15 and connects to the access point. In this example, No. 3 is connected to the access point whose SSID is MyHome, that is, the access point 3 in FIG. 1 using the stored authentication information.

  On the other hand, when the control unit 24 recognizes in step 209 that the wireless unit 25 has received the receipt notification, the control unit 24 sets the authentication information of the selected access point for the wireless unit 25 and accesses the wireless terminal 25. Connect to the point. In this example, No. 3 is connected to the access point whose SSID is MyHome, that is, the access point 3 in FIG. 1 using the stored authentication information.

  By performing the above-described operation, the wireless unit 15 of the television 1 and the wireless unit 25 of the wireless terminal 2 are each set with authentication information to be connected to the access point 3, and perform secure communication with the access point 3. A wireless network can be configured. This is the wireless network shown in FIG. 4, and the simple operation of simply selecting an access point to be connected from the list in the wireless terminal 2 without inputting complicated authentication information on the television 1 using the remote controller 100. By doing so, a network in which all the wireless LAN devices are connected can be configured, and furthermore, the television 1 and the wireless terminal 2 can be connected to the external network 4.

  In addition, since the television 1 and the wireless terminal 2 are performing wireless communication via the access point 3, the wireless terminal 2 can control the television 1, or conversely, the television 1 can control the wireless terminal 2. . For example, it is assumed that the input unit 26 of the wireless terminal 2 receives an instruction to change the channel selected by the tuner 11 from the user. The control unit 24 transmits the received change instruction from the wireless unit 25 to the wireless unit 15. The control unit 14 of the television 1 instructs the tuner 11 to change the channel selection channel according to the change instruction received by the wireless unit 15. With such an operation, the user can control the television 1 using the wireless terminal 2.

  As an opposite example, it is assumed that, for example, the remote control receiving unit 16 of the television 1 receives a shooting instruction for the camera 21 from the user from the remote control 100. The control unit 14 transmits the received shooting instruction from the wireless unit 15 to the wireless unit 25. The control unit 24 of the wireless terminal 2 instructs the camera 21 to start photographing according to the photographing instruction received by the wireless unit 25. With such an operation, the user can control the wireless terminal 2 using the television 1.

  Moreover, no matter what authentication method the access point 3 to be connected uses, the television 1 once operates as an access point to establish a wireless connection with the wireless terminal 2 and the access point 3 and the wireless terminal 2 are connected. Authentication information is transmitted from the wireless terminal 2 to the television 1 and the television 1 sets the authentication information. When the television 1 is restarted as a station, the television 1 and the access point 3 A wireless network for secure communication can be configured.

  Needless to say, even if the access point 3 does not have a display unit, there is no problem in the operation of this embodiment.

  Next, operations different from those in the first embodiment will be described with reference to FIG. The operation of the television 1 is the same as in FIG. The control of the wireless terminal 2 is the same up to step 204. Under the control of steps 101-105 and 201-204, the television 1 and the wireless terminal 2 establish a wireless connection for performing secure communication as shown in the state of FIG. If the connection is established, the display of the video information on the display unit 12 may be stopped.

  Next, in step 121, the control unit 14 of the television 1 transmits an access point authentication information acquisition request stored in the wireless terminal 2 from the wireless unit 15 to the wireless unit 25 of the wireless terminal 2. Upon receiving the acquisition request, the wireless terminal 2 reads the access point authentication information from the storage unit 23 in step 205. In this case, all the access point authentication information shown in FIG. 7 is read. In step 221, the read access point authentication information is transmitted from the wireless unit 25 to the wireless unit 15 of the television 1.

  In the television 1, in step 122, the control unit 14 acquires the access point authentication information received by the wireless unit 15. Next, in step 123, the control unit 14 displays a list of access points on the display unit 12 using the acquired information. The display on the display unit 12 may be displayed as shown in FIG. 8 as described in the example of the wireless terminal 2. That is, the display unit 12 displays only the SSIDs of the four access points that the wireless terminal 2 has connected to in the past or has been input by the user in the past, and prompts the user to select the access point to be connected. .

  At this time, the access point authentication information acquired by the control unit also includes information on the wireless system, and thus the access point displayed on the display unit 12 may be limited using this. For example, if it is revised that the wireless system supported by the wireless unit 15 is only IEEE 802.11a, No. in FIG. 1 and no. Since the second access point does not support IEEE802.11a, it cannot be connected. Therefore, the access point displayed on the display unit 12 is NO. 3 and no. Only 4 is enough. As for the authentication method and the encryption method, the access point authentication information is checked, and the access point using the method not supported by the wireless unit 15 can be prevented from being displayed on the display unit 12. Thus, the wireless unit 15 does not display the access points that cannot be connected, thereby preventing the user from making unnecessary selections.

  Next, at step 124, remote control receiving unit 16 receives an access point selection input transmitted by the user using remote control 100. In this embodiment, the user wants to connect to the access point 3 in FIG. 3, the access point whose SSID is MyHome is selected.

  Subsequently, in step 125, the control unit 14 transmits a notification indicating which access point has been selected from the wireless unit 15 to the wireless unit 25. In this embodiment, the user is no. No. 3 access point is selected. A notification that the third access point has been selected is transmitted. In the wireless terminal 2, in step 222, the control unit 24 transmits a receipt notification that the notification has been received from the wireless unit 25 to the wireless unit 15.

  Further, the television 1 performs the same operation as in FIG. 5 after receiving the receipt notification. That is, in step 107, the control unit 14 restarts the wireless unit 15 as a station. Subsequently, in step 108, the control unit 14 sets authentication information of the selected access point to the wireless unit 15, and connects to the access point. In the present embodiment, No. 1 whose SSID is MyHome. 3 is connected to the access point 3, that is, the access point 3 of FIG. 1 using the stored authentication information.

  On the other hand, the operation of step 209 is the same as that in FIG. 5 for the wireless terminal 2, and the control unit 24 sets the authentication information of the selected access point for the wireless unit 25 and connects to the access point. In the present embodiment, No. 1 whose SSID is MyHome. 3 is connected to the access point 3, that is, the access point 3 in FIG. 1 using the authentication information stored in the storage unit 23.

  By performing the above-described operation, the wireless unit 15 of the television 1 and the wireless unit 25 of the wireless terminal 2 are set with authentication information to be connected to the access point 3, and wirelessly perform secure communication with the access point 3. A network can be configured. This is the wireless network shown in FIG. 4. By inputting authentication information on the television 1 using the remote control 100, the television 1 can be simply operated by selecting an access point to be connected from the list. A network in which all wireless LAN devices are connected can be configured.

  Moreover, no matter what authentication method the access point 3 to be connected uses, the television 1 once operates as an access point to establish a wireless connection with the wireless terminal 2 and the access point 3 and the wireless terminal 2 are connected. Authentication information is transmitted from the wireless terminal 2 to the television 1 and the television 1 sets the authentication information. Therefore, when the television 1 is restarted as a station, the television 1 and the access point 3 A wireless network for secure communication can be configured.

  Needless to say, even if the access point 3 does not have a display unit, there is no problem in the operation of this embodiment.
