It is a figure which shows the example of a display of use permission conditions.

  An embodiment for carrying out the present invention will be described. FIG. 1 is a diagram showing a configuration of each wireless network and wireless communication terminals forming these in one embodiment of the present invention. For explanation, the wireless communication terminal 100, the wireless communication terminal 300, and the wireless communication terminal 400 form the wireless network 1, and the wireless communication terminal 200, the wireless communication terminal 500, and the wireless communication terminal 600 are wireless. It is assumed that the network 2 is formed, and the wireless communication terminal 700 and the wireless communication terminal 800 form the wireless network 3. Furthermore, it is assumed that the wireless communication terminal 100 and the wireless communication terminal 200 are arranged in a range where the user can manually operate.

  The wireless communication terminal 100 includes an operation unit 101, a wireless communication unit 102, a control unit 103, a storage unit 104, and a display unit 105. The wireless communication terminals 200 to 800 have the same configuration. For example, in the wireless communication terminal 200, the operation unit 101 corresponds to the operation unit 201, the wireless communication unit 102 corresponds to the wireless communication unit 202, the control unit 103 corresponds to the control unit 203, and the storage unit 104 corresponds to the storage unit 204. The display unit 105 corresponds to the display unit 205.

  The operation unit 101 is an operation detection unit such as an operation button, for example, and outputs a pressing operation signal to the control unit 103 when a pressing operation is detected. For example, the operation unit 101 is an operation button displayed as “YES” or “NO” on the display screen for permitting connection authentication, and when “YES” is pressed, An operation signal is output to the control unit 103. Further, the operation unit 101 outputs a negative operation signal to the control unit 103 when detecting that “NO” is pressed. The operation unit 101 and the display unit 105 may be the same device. For example, an operation button may be displayed on the display unit 105.

  The wireless communication unit 102 transmits a beacon frame to each wireless communication terminal at a predetermined cycle. Here, the beacon frame is a packet including network data. The network data includes a network identifier and attribute data. The network identifier is an identifier indicating the wireless network 1 to which the own terminal (wireless communication terminal 100) belongs. The attribute data is data related to the wireless network 1 to which the own terminal (wireless communication terminal 100) belongs. For example, “use permission conditions to be observed because the authentication requesting terminal belongs to the wireless network 1”, “wireless network 1 This is data indicating “formation purpose (for example, video content viewing purpose, game battle purpose)” and the like. Network data or the like may be included in the “Vender Specific” area of the “Frame Body” area of the IEEE 802.11 standard beacon frame. In addition, because the beacon frame includes pointer data, other frames indicated by the pointer data (hereinafter referred to as “accompanying beacon frame”) are also transmitted to each wireless communication terminal in a predetermined cycle including network data. It is good.

  The wireless communication unit 102 receives a beacon frame and an accompanying beacon frame from wireless communication terminals belonging to another wireless network, and transmits network data included in the received frames to another wireless network (wireless network 2 or 3). ) To the control unit 103 as network data. When the wireless communication unit 102 receives an authentication instruction signal from the control unit 103, the wireless communication unit 102 includes connection setting data (for example, an identifier indicating a communication encryption method, a common (encryption) key), and connection setting authentication data used for authentication processing. Are transmitted to and received from the wireless communication terminal of the communication destination. The wireless communication unit 102 outputs the connection setting authentication data received from another wireless communication terminal to the control unit 103.

  When the wireless communication terminal 100 operates as an authentication requesting terminal, the wireless communication unit 102 receives a connection start instruction signal from the control unit 103 and transmits a probe request (Probe Request) (connection setting request data) including a pressing operation signal. To do. In addition, the wireless communication unit 102 receives a probe response and outputs data (for example, a pressing operation signal and a network identifier) included in the probe response to the control unit 103.

  On the other hand, when the wireless communication terminal 100 operates as an authentication terminal, the wireless communication unit 102 receives a connection start instruction signal from the control unit 103, and confirms that the wireless network 1 to which the terminal belongs and the authentication terminal. The probe response including the indicated data and the pressing operation signal is transmitted to the wireless communication terminal that is the probe request transmission source. Thus, the probe request and the probe response are used by the authentication requesting terminal that has transmitted the probe request and the authentication terminal that has transmitted the probe response to start the wireless connection setting.

  The control unit 103 acquires network data included in a beacon frame received by the wireless communication unit 102 from other wireless networks (wireless networks 2 and 3) from the wireless communication unit 102, and includes a network identifier included in the network data and , And attribute data are stored in the storage unit 104 in association with each other.

  If the wireless communication terminal 100 has not yet formed the wireless network 1 and a pressing operation signal is input from the operation unit 101, the wireless communication terminal 100 becomes an authentication requesting terminal (Enrollee). Here, the control unit 103 transmits a wireless connection setting start instruction signal for instructing start of wireless connection setting to the wireless communication unit 102 in order to transmit a probe request.

  When the wireless communication terminal 100 forms the wireless network 1 and an operation signal is input from the operation unit 101, the control unit 103 displays “cuts off the connection with the currently connected wireless network” on the display unit 105. ”Is displayed (described later in FIG. 3), and the network connection disconnection process or whether to newly connect to the wireless network is switched in response to the next positive operation signal or negative operation signal input. . Here, when a positive operation signal is input, the wireless communication terminal 100 becomes an authentication requesting terminal (Enrollee). Here, the control unit 103 transmits a wireless connection setting start instruction signal to the wireless communication unit 102 in order to transmit a probe request.

  In addition, the control unit 103 acquires the network identifier included in the probe response from the wireless communication unit 102, selects network data corresponding to the acquired network identifier from the network data stored in the storage unit 104, and selects the selected network data. The network data is displayed on the display unit 105. Thereafter, when an affirmative pressing operation signal is input from the operation unit 101, the control unit 103 transmits the connection setting data to another wireless communication terminal that is an authentication terminal, and further performs authentication to transmit / receive the connection setting authentication data. An instruction signal is transmitted to the wireless communication unit 102.

  On the other hand, when the push operation signal is input from the operation unit 101 while the wireless communication terminal 100 is connected to the network and no positive operation signal is input thereafter, the wireless communication terminal 100 becomes an authentication terminal (registrar, Registrar). Here, the control unit 103 transmits a wireless connection setting start instruction signal to the wireless communication unit 102 in order to transmit a probe response including a pressing operation signal. In addition, the control unit 103 receives connection setting data from another wireless communication terminal that is an authentication requesting terminal, and transmits an authentication instruction signal to the wireless communication unit 102 in order to transmit and receive connection setting authentication data.

  The display unit 105 is a display (for example, a liquid crystal display screen) or the like, and displays network data or the like according to instructions from the control unit 103. The storage unit 104 stores network data and the like according to instructions from the control unit 103.

  FIG. 2 is a flowchart showing the operation of the wireless communication terminal in one embodiment of the present invention. As described above, the wireless communication terminals 100 to 800 have the same configuration. For this reason, which wireless communication terminal is the authentication terminal (registrar) and which other wireless communication terminal is the authentication requesting terminal (enrollee) is determined by the user's operation. For example, when the user presses down the operation buttons of both the wireless communication terminal 100 and the wireless communication terminal 200 among the wireless communication terminals 100 to 800, one of the two terminals becomes an authentication terminal (registrar), and the rest Becomes an authentication requesting terminal (enrollee). Furthermore, when the user performs a pressing operation (affirmative operation) on the operation unit 101 of the wireless communication terminal 100, the wireless communication terminal 100 is determined as an authentication requesting terminal, and the remaining wireless communication terminals 200 are determined as authentication terminals. In addition, since the other wireless communication terminals are not pressed (affirmed), they are not authentication request terminals or authentication terminals.

  In the following, as an example, when the wireless communication terminal 100 belonging to the wireless network 1 disconnects from the wireless network 1 and comes to belong to the wireless network 2, the wireless communication terminal 100 is connected to the authentication requesting terminal and the wireless communication terminal. The description will be continued with 200 as an authentication terminal. The control unit 103 of the wireless communication terminal 100 that has become an authentication requesting terminal by a user operation executes Steps S1 to S3 or Steps S1 to S5 and Steps S10 to S19. On the other hand, the control unit 203 of the wireless communication terminal 200 that has become the authentication terminal executes Steps S20 and S21 from Steps S1 to S5, Steps S6 to S9, or Step S6.

  The wireless communication unit 102 of the wireless communication terminal 100 transmits the beacon frame and the accompanying beacon frame received from the wireless communication terminals belonging to another wireless network at a predetermined cycle to the control unit 103 as network data of the other wireless network. Output. The control unit 103 stores the network identifier in the storage unit 104 in association with the attribute data of the wireless network indicated by the network identifier. Since the beacon frame is transmitted at a predetermined cycle, these operations are performed periodically, and the network data is updated and stored in the storage unit 104 (step S1).

  Next, the control unit 103 of the wireless communication terminal 100 determines whether or not a pressing operation signal is input from the operation unit 101 (first operation input) (step S2). When the pressing operation signal is input, the control unit 103 of the wireless communication terminal 100 determines whether or not it is connected to the network (step S3).

  FIG. 3 is a diagram showing a display example indicating that the connection with the currently connected network is disconnected. When the wireless communication terminal 100 is connected to the wireless network, the control unit 103 causes the display unit 105 to display “to disconnect from the currently connected wireless network” (step S4). Next, the control unit 103 determines whether a positive operation signal is input from the operation unit 101. Steps S1 to S5 are processing common to the authentication requesting terminal and the authentication terminal (step S5).

  When an affirmative operation signal is input from the operation unit 101, the wireless communication terminal 100 becomes an authentication request terminal (enrollee). Therefore, the control unit 103 transmits a wireless connection setting start instruction signal to instruct the wireless communication unit 102 to transmit a probe request. The wireless communication unit 102 receives a connection start instruction signal from the control unit 103, and sends a probe request including a pressing operation signal to one or more wireless communication terminals that have received a beacon frame and that exist around the wireless communication terminal 100. It transmits sequentially (step S10).

  On the other hand, the control unit 203 that has not received an affirmative operation signal from the operation unit 201 determines whether a probe request has been received (step S6). When the probe request is received, the wireless communication terminal 200 becomes an authentication terminal (registrar). Therefore, the control unit 203 transmits a wireless connection setting start instruction signal to instruct the wireless communication unit 202 to transmit a probe response. The wireless communication unit 202 receives the wireless connection setting start instruction signal from the control unit 203, and transmits a probe response including a pressing operation signal and a network identifier as a positive response to the probe request (step S7).

  Next, the wireless communication unit 202 determines whether or not connection setting data (such as a common key) included in an EAP (Extensible Authentication Protocol) request is received within a predetermined time from the wireless communication terminal 100 that is an authentication requesting terminal. judge. When the connection setting data is received within a predetermined time, the wireless communication unit 202 transmits an EAP response as a response to exchange the common key, and the process proceeds to step S9. On the other hand, when the connection setting data is not received within the predetermined time, the wireless communication unit 202 ends the process (step S8).

  FIG. 4 is a sequence diagram showing a wireless network connection setting procedure in WPS. The control unit 203 receives an EAP request and transmits an EAP response, so that connection authentication processing (SSID (Service Set Identifier), encryption method and PIN (Personal Identification Number) code related to encryption, etc.) can be set. Notification of necessary information) is executed (step S9).

  The wireless communication unit 102 of the wireless communication terminal 100 receives the probe response and outputs it to the control unit 103. Thereby, the control part 103 can detect that the radio | wireless communication terminal 200 exists as an authentication terminal in the radio | wireless network 2 (step S11). The control unit 103 determines whether or not data (positive response) indicating that the terminal is an authentication terminal is included in the probe response (step S12). When the pressing operation signal is included in the probe response, the control unit 103 selects and acquires network data corresponding to the network identifier included in the probe response from the storage unit 104 (step S13).

  FIG. 5 is a diagram illustrating a display example of wireless networks existing around the authentication requesting terminal. Here, radio wave intensity status, security status (icon), SSID (Service Set Identifier), wireless communication standards (a, b, g), and the like are displayed, and further, detailed information (attributes) of the wireless network There is a “detail” button to know the data. FIG. 6 is a diagram illustrating a display example of the use permission condition. When the “detail” button is pressed in the display of FIG. 5, detailed information (attribute data) of the wireless network is displayed. Thereby, the user can select whether or not to agree to the use permission condition. In FIG. 6, the authentication request terminal is connected to the wireless network by pressing the “Agree and Connect” button. The control unit 103 instructs the display unit 105 to display the selected network data. Accordingly, the display unit 105 displays the network identifier, “use permission conditions to be observed because the wireless communication terminal 100 belongs to the wireless network”, “the purpose of forming the wireless network (for example, the purpose of viewing video content, the purpose of playing games, etc.) ) "And the like are displayed (step S14).

  Next, the control unit 103 of the wireless communication terminal 100 determines whether or not an affirmative operation signal has been input (second operation input) (step S15). When a negative operation signal is input, the control unit 103 returns to step S10. When the affirmative operation signal is input, the control unit 103 transmits an authentication instruction signal for transmitting connection setting data (for example, an identifier indicating a communication encryption method, a common (encryption) key) to the wireless communication unit 102. As a result, the wireless communication unit 102 transmits the connection setting data included in the EAP request (step S16).

  In addition, the control unit 203 of the wireless communication terminal 200 transmits an EAP request and receives an EAP response, thereby executing connection authentication processing (deciding settings such as IBSS) (FIG. 4). As a result, the wireless communication terminal 100 is authenticated for connection to the wireless communication terminal 200, and the wireless communication terminal 100 belongs to the wireless network 2. (Step S17).

  In step S12, when the probe response does not include the pressing operation signal, it is considered that the probe response transmitted from the authentication terminal (for example, the wireless communication terminal 700) belonging to the irrelevant wireless network 3 is received. In order to find the wireless communication terminal 200, it is determined based on the network data stored in the storage unit 104 whether or not the probe request has been transmitted to all other terminals that are periodically transmitting beacon frames (step S104). S18).

  When the probe request has not been transmitted to all the other terminals that periodically transmit the beacon frame, the control unit 103 returns to step S10. On the other hand, if not, the control unit 103 instructs the display unit 105 to display that “the wireless communication terminal 200 cannot be detected as an authentication terminal in the wireless network 2” (step S19).

  In step S6, when a probe request is not received from the wireless communication terminal 100, it is determined whether or not a predetermined time has elapsed. If the predetermined time has not elapsed, the control unit 203 returns to step S6 (step S20). When the predetermined time has elapsed, the control unit 203 instructs the display unit 205 to display “the connection setting data could not be transmitted / received”. As a result, the display unit 205 displays “notifying that connection setting data could not be transmitted / received”.

  As described above, according to the embodiment of the present invention, in the wireless network, the authentication requesting terminal notifies the user of the attribute data of the wireless network to which the authentication terminal belongs before being authenticated by the authentication terminal, and when the authentication instruction is received from the user. Since only the connection authentication is performed, the user can participate only in the wireless network to which the user desires to connect.
