Description

  The present invention relates to a wireless LAN communication parameter setting method and an access point, and more particularly to a wireless LAN communication parameter setting method and an access point in which a switch is provided in a wireless LAN access point and the wireless LAN setting is performed by a switch operation.

  There is a standard called IEEE (Institute of Electrical and Electronic Engineers) 802.11 as a communication method when a terminal equipped with a wireless LAN uses the Internet via a wireless LAN access point (AP). This standard stipulates that a predetermined procedure called association is performed between the AP and the terminal so that the AP can identify the presence of the terminal.

  An identifier called a network name (SSID) is used to identify the AP that performs this association. When a wireless LAN terminal user selects an AP to be associated with, it is necessary to set the same SSID for both the AP and the terminal. In addition to this, an encryption method for encrypting signals transmitted and received between the AP and the terminal so that highly confidential information can be protected even if a wireless LAN communication path is intercepted by a third party. It is necessary to set the same encryption key (KEY) on both the AP and the terminal.

  Conventionally, when setting communication parameters to both the AP and the terminal in the same way, the user is often forced to perform complicated manual operations. In response to such a technical problem, Patent Document 1 provides a manual switch in the AP, and when this switch is operated, a time window is opened for a predetermined time, and only when the time window is open from the client. A technique for accepting a setting request is disclosed.

  Patent Document 2 discloses a technique for easily setting communication parameters for the purpose of reducing the operation burden on the user. Specifically, the communication parameter setting can be completed by executing the switch operation on the wireless LAN terminal side and the switch operation on the AP side almost simultaneously. An example of a communication parameter setting procedure according to Patent Document 1 will be described below.

  Procedure 1: Publicize the SSID to the surroundings by pressing the button switch provided on the AP.

  Procedure 2: By depressing a button switch provided on the terminal, an AP that is advertising the SSID is detected and a temporary communication path is established.

  Procedure 3: The communication parameters used by the AP for normal data communication are automatically generated and transmitted to the terminal using the temporary communication path.

  Procedure 4: The terminal receives the communication parameters and resets itself.

  In Patent Document 1, a time window for accepting settings is opened when an AP switch is operated, and a setting operation is accepted only within this time window. However, since the priority within the time window is first-come-first-served basis, the authorized user who owns the AP owns the AP earlier than the authorized user within the time window after executing the AP switch operation. If a setting request is executed by a malicious third party, the third party responds. It is necessary to avoid the AP being used by a malicious third party who does not own the AP.

  In the case of Patent Document 2, in a technology in which button switches are provided on both a wireless LAN terminal and an AP, and communication parameters are set by operating both switches simultaneously, a plurality of terminals are included in the wireless coverage of one AP. If there is a button pressed on multiple terminals at the same time as the AP button is pressed in an environment where all the terminals exist, the setting of all terminals fails from the security viewpoint. The reason for this is that only authorized AP users want to use the wireless LAN. Such a function is strongly desired particularly for a wireless LAN used in a general home.

  However, a malicious third party who does not own the AP is located within the wireless coverage of the AP outside the home of the authorized user who owns the AP, and continues to press the button on the terminal aiming at the AP button pressing timing. If it is executed, even if it is an authorized user of the AP, the wireless LAN setting cannot be completed unless a malicious third party quits the button pressing operation on the terminal.

  An object of the present invention is to provide a wireless LAN communication parameter setting method and an access point that can solve the above-described problems of the prior art and can safely and easily set parameters for a wireless LAN communication for a regular user. is there.

  In order to achieve the above object, the present invention is characterized in that the following measures are taken.

  (1) In a wireless LAN communication parameter setting method for setting a parameter for communication with an access point in a wireless LAN terminal, a first communication parameter for establishing a first communication path between the access point and the terminal; Second communication parameters for establishing the second communication path are stored in advance, and the first communication parameters are stored in advance in the terminal. Then, in response to a setting request from the terminal, the access point establishes the first communication path with the terminal using the first communication parameter, and the access point establishes the first communication path. A procedure for setting a different time slot for each set terminal, a procedure for the access point notifying each terminal of the set time slot via the first communication path, and an access point provided in the access point The procedure for detecting the connection request operation to the switch, the access point confirms the validity of the connection request operation, and the only connection request in which the connection request operation is detected within the time slot period set for each time slot. The procedure for certifying that it is an operation, and the access point corresponds to the time slot of the connection request operation that has been authorized. And a procedure for notifying the to have kicked terminal second communication parameter, based on a second communication parameter, and as a second communication path is established between the terminal and the access point.

  (2) a first communication parameter storage means for storing a first communication parameter for establishing a first communication path with a wireless LAN terminal at a wireless LAN access point having a switch for accepting a user operation; In response to a setting request signal received from a terminal, second communication parameter storage means for storing a second communication parameter for establishing a second communication path with the terminal, and the first communication with the terminal. Communication path establishing means for establishing a first communication path using communication parameters; time slot assigning means for assigning a time slot to each terminal for which the first communication path is established; and each time slot in the first communication path. Time slot notification means for notifying the terminal, connection request detection means for detecting a connection request operation for the switch, and the validity of the connection request operation. To the terminal associated with the time slot of the connection request operation that has been justified, and means for recognizing that it is the only connection request operation detected within the time slot period including all of the time slots Means for notifying the second communication parameter, and a second communication path is established with the terminal based on the second communication parameter.

  According to the present invention, the following effects are set.

  (1) In the present invention, a time slot is assigned to each terminal that has made a setting request to a wireless LAN access point, and it is required to operate a switch of the access point within the time slot. And since only the terminal to which the time slot in which the switch operation is detected is assigned is authorized as a regular user terminal, there are a plurality of terminals within the radio coverage of one access point, and each terminal has one A wireless LAN communication path can be established only with a legitimate user's terminal even in an environment where connection requests are made simultaneously to an access point.

  (2) Since the terminal user only has to operate the switch of the access point within the time slot assigned to himself / herself, the user is free from complicated operations in the wireless LAN setting.

[First embodiment]
FIG. 4 is a sequence flow showing the operation of the first embodiment of the present invention, and FIG. 5 is a flowchart showing the operation of the wireless AP 1a in the first embodiment.

  When the user SW presses the button SW 203a of the wireless LAN terminal 2a at time t1, a setting request message is transmitted from the wireless LAN terminal 2a. In the wireless AP 1a, when the setting request is detected in step S1, a connection process is executed using the first communication parameters SSIDcom and KEYcom in step S2, and the communication path establishment units 104a and 204a perform the connection processing at time t2. A setting communication path La protected by AES encryption is established between the wireless AP 1a and the wireless LAN terminal 2a.

  At substantially the same time, when the user B presses down the button SW 203b of the wireless LAN terminal 2b at time t3, the connection process using the first communication parameters SSIDcom and KEYcom is executed in the same manner. A setting communication path Lb protected by AES encryption is similarly established between the AP 1a and the wireless LAN terminal 2b.

  In step S3, at time t5, time slots ts assigned to the wireless LAN terminals 2a and 2b as connection operation periods are set by the time slot assignment unit 104b and registered in the time slot management table. Here, a time slot ts1 (for example, 12:00 to 12:03) is assigned to the wireless LAN terminal 2a, and a time slot ts2 (for example, 12:03 to 12:00) is assigned to the wireless LAN terminal 2b. 06 minutes) will continue to be explained.

  In step S4, the time slot ts1 is notified to the wireless LAN terminal 2a at time t6 by the time slot notification unit 104c, and the time slot ts2 is notified to the wireless LAN terminal 2b at time t7. The notification of each of the time slots ts1 and ts2 is performed through the IP communication path protected by HTTPS in the setting communication paths La and Lb protected by the AES encryption.

  At time t8, a message requesting that the button SW103a of the wireless AP 1a be pressed in the time slot ts1 is displayed on the display panel 203b of the wireless LAN terminal 2a of the user A, for example, together with a downcount until the start time of the time slot ts1. Is done. At time t9, a message requesting to press the button SW 103a of the wireless AP 1a in the time slot ts2 is similarly displayed on the display panel 203b of the wireless LAN terminal 2b of the user B.

  Thereafter, at time t10 at which the time slot ts1 starts, a message requesting a pressing operation of the button SW 103a of the wireless AP 1a is displayed on the display panel 203b of the wireless LAN terminal 2a. At time t12 at which the time slot ts2 starts, a message requesting a pressing operation of the button SW 103a of the wireless AP 1a is displayed on the display panel 203b of the wireless LAN terminal 2b.

  When the user A presses down the button SW 103a of the wireless AP 1a in the time slot ts1, and this is detected by the connection request detection unit 104d in step S5, the operation time t11 is registered in step S6. Note that the user B of the wireless LAN terminal 2b cannot press the button SW 103a of the wireless AP 1a, so that the operation time by the user B is not registered. In step S7, it is determined whether or not the time slot period in which the time slot ts is set has ended. Until the time slot ends, the process returns to step S5 and the above procedure is repeated.

  When the time slot period (here, ts1, ts2) ends, the process proceeds to step S8, and at time t13, whether or not a valid connection operation for the wireless AP 1a is detected is determined by the validity determination unit 104e.

  In the present embodiment, it is determined whether or not there is only one time slot in which the pressing operation of the button SW 103a is detected in the time slot period. If there is only one, the pressing operation is determined as a valid connection operation. The In the above example, the pressing operation is not detected once in the time slot ts2, but is detected only once in the time slot ts1 at the time t11. That is, only one time slot ts1 is the time slot in which the button SW 103a is pressed during the time slot period. Therefore, in this embodiment, only the pressing operation in the time slot ts1 is determined as a valid connection operation.

  In step S9, at time t14, the communication path La protected by the AES is transmitted to the wireless LAN terminal 2a associated with the time slot ts1 in the time slot management table by the second communication parameter notification unit 104f. The second communication parameters SSIDx and KEYx for this communication are notified through the IP communication path protected by HTTPS.

  In Step S10, at time t15, a setting completion message in which a BSSID (Basic Service Set Identifier) is described is notified to the wireless LAN terminal 2b associated with the time slot ts2 in which a valid connection operation cannot be detected. . In step S11, the main communication path (second communication path) of the wireless LAN is established by the communication path establishment units 104a and 204a using the second communication parameters SSIDx and KEYx with the wireless LAN terminal 2a. The wireless LAN terminal 2b that has received the setting completion message confirms the number of setting SSIDs and BSSIDs found in the search when the button SW203b is pressed at time t16, and the number is one. If the confirmed BSSID matches the BSSID included in the above notification, the fact that the wireless LAN setting has failed is displayed on the UI at time t17.

[Second Embodiment]
FIG. 6 is a sequence flow showing the operation of the second embodiment of the present invention, and FIG. 7 is a flowchart showing the operation of the wireless AP 1a in the second embodiment. Since the processing up to time t11 is the same as in the first embodiment, the description thereof will be omitted.

  User A assigned time slot ts1 presses button SW103a of wireless AP 1a at time t11 in regular time slot ts1, and erroneously presses button SW103a at time t13 in next time slot ts2. In step S8, based on the fact that the button SW 103a is pressed in two time slots at time t14, it is determined that a valid connection operation has not been detected, and the process proceeds to step S12. In step S12, it is determined whether or not the reset period or the reset count has timed out, and the process returns to step S3 and the reset is repeated until the time is up.

  In step S3, at time t15, the time slot ts is reset in each wireless LAN terminal 2a, 2b and registered in the time slot management table. Here, the description will be continued assuming that the time slot ts3 is assigned to the wireless LAN terminal 2a and the time slot ts4 is assigned to the wireless LAN terminal 2b.

  In step S4, the time slot ts3 is notified to the wireless LAN terminal 2a at time t16, and the time slot ts4 is notified to the wireless LAN terminal 2b at time t17. The notification of the time slots ts3 and ts4 is also performed by the IP communication path protected by HTTPS in the setting communication paths La and Lb protected by the AES encryption.

  At time t18, a message requesting that the button SW 103a of the wireless AP 1a is pressed in the time slot ts3 is displayed on the display panel 203b of the wireless LAN terminal 2a of the user A. At time t19, a message requesting to press the button SW 103a of the wireless AP 1a in the time slot ts4 is similarly displayed on the display panel 203b of the wireless LAN terminal 2b of the user B.

  Then, if the pressing operation of the button SW 103a is detected at time t22 in the time slot ts4 and this is the only pressing operation detected in the time slot period (ts3, ts4), this is a valid connection operation in step S8. Determination is made and the process proceeds to step S9 and subsequent steps.

  Such a resetting operation is repeated until a valid connection operation is detected in step S8 or until it is determined in step S12 that the number or time of the resetting operation has timed out.

[Example 3]
FIG. 8 is a sequence flow showing the operation of the third embodiment of the present invention, and FIG. 9 is a flowchart showing the operation of the wireless AP 1a in the third embodiment.

  When the user SW presses the button SW 203a of the wireless LAN terminal 2a at time t1, a setting request message is transmitted from the wireless LAN terminal 2a. In the wireless AP 1a, when the setting request is detected in step S1, a connection process is executed using the first communication parameters SSIDcom and KEYcom for establishing the setting communication path in step S2, and at time t2, A setting communication path La protected by AES encryption is established with the wireless LAN terminal 2a.

  Almost simultaneously with this, when the button SW 203b of the wireless LAN terminal 2b is pressed by the user B at time t3, the connection processing using the first communication parameters SSIDcom and KEYcom is performed in the same manner. A setting communication path Lb protected by AES encryption is similarly established with the wireless LAN terminal 2b.

  In step S3a, at time t5, the operation pattern of the time slot ts and the button SW 103a assigned as the connection operation period to each of the wireless LAN terminals 2a and 2b is set and registered in the time slot management table. The operation pattern is the number of times the user presses the button SW 103a, the pressing time, or the pressing rhythm, and a specific operation pattern is set for each user of the wireless LAN terminals 2a and 2b.

  Here, it is assumed that the time slot ts2 is assigned to the wireless LAN terminal 2a and the time slot ts1 is assigned to the wireless LAN terminal 2b. Further, as operation patterns, it is assumed that the wireless LAN terminal 2a is assigned “press button SW twice” and the wireless LAN terminal 2b is assigned “press button SW once”.

  In step S4a, the wireless LAN terminal 2a is notified of the time slot ts2 and “button SW is pressed twice” at time t6, and the time slot ts1 and “button SW is pressed once” to the wireless LAN terminal 2b at time t7. Will be notified.

  At time t8, a message requesting that the button SW103a of the wireless AP 1a is pressed twice in the time slot ts2 is displayed on the display panel 203b of the wireless LAN terminal 2a, for example, with a downcount until the start time of the time slot ts2. . At time t9, a message requesting that the button SW 103a of the wireless AP 1a is pressed once in the time slot ts1 is similarly displayed on the display panel 203b of the wireless LAN terminal 2b of the user B.

  Thereafter, at time t10 at which the time slot ts1 starts, a message requesting a pressing operation of the button SW 103a of the wireless AP 1a is displayed on the display panel 203b of the wireless LAN terminal 2b. At time t11 when the time slot ts2 starts, a message requesting a pressing operation of the button SW 103a of the wireless AP 1a is displayed on the display panel 203b of the wireless LAN terminal 2a.

  When the user A presses the button SW103a of the wireless AP 1a twice in the time slot ts2, and this is detected in step S5, the pressing time t12 and the number of pressings are registered in step S6. In step S7, it is determined whether or not the time slot period has ended. Until the time slot period ends, the process returns to step S5 and the above procedure is repeated.

  When the time slot period ends, the process proceeds to step S8a, and it is determined whether or not a valid connection operation is detected at time t13. In the present embodiment, if there is only one time slot in which the pressing operation of the button SW 103a is detected and the number of pressings matches the operation pattern, the pressing operation is determined as a valid connection operation. The

  In the above example, the pressing operation is not detected once in the time slot ts1, but the pressing operation is detected only once at the time t12 in the time slot ts2. That is, since the time slot in which the button SW 103a is pressed during the time slot period is only the time slot ts2, and the operation pattern matches, only the pressing operation in the time slot ts2 is determined to be a valid connection operation. The

  In the above embodiment, the operation pattern is described as the number of times of pressing, the pressing time, or the pressing rhythm. However, the present invention is not limited to this, and the wireless AP 1a is provided with a plurality of operation switches. A switch that is selectively operated from a plurality of switches may be defined as an operation pattern.

[Example 4]
FIG. 10 is a sequence flow showing the operation of the fourth embodiment of the present invention, and FIG. 11 is a flowchart showing the operation of the wireless AP 1a in the fourth embodiment. Since the processing up to time t10 (steps S1 to S7) is equivalent to that of the first embodiment, the description thereof will be omitted. Here, the time slot ts1 is assigned to the wireless LAN terminal 2a, and the time slot ts2 is assigned to the wireless LAN terminal 2b.

  In step S8, it is determined whether or not there is only one time slot in which the pressing operation of the button SW 103a is detected in the time slot period. If there is only one, the pressing operation of the button SW 103a detected at time t12 is determined. It is temporarily determined that the connection operation is valid.

  At this time, in the first embodiment, since the pressing operation of the button SW103a is detected only in the time slot ts2, a correct judgment is made immediately. In this embodiment, the pressing of the button SW103a is performed in the time slot st1. Considering the possibility of an erroneous operation in which the authorized user to be operated has accidentally pressed the button SW 103a in the time slot ts2, the process proceeds to step S8a.

  In step S8a, at time t14, a message requesting re-pressing of the grace slot and the button SW 103a in the grace slot is transmitted to the wireless LAN terminal 2a to which the time slot st1 for which the push operation has not been detected is assigned. . At time t15, a message is displayed on the display panel 203b of the wireless LAN terminal 2a requesting that the button SW 103a of the wireless AP 1a be pressed in the grace slot.

  Thereafter, when the user A presses the button SW 103a of the wireless AP 1a at time t16 in the grace slot and this is detected in step S8b, the switch operation detected at the time t12 may be an erroneous operation. Return to S3. On the other hand, if no button operation is detected in the grace slot, the switch operation that has been provisionally determined to be valid at time t12 is regarded as truly valid, and the process proceeds to step S9 and subsequent steps.
