In the wireless LAN devices of Patent Documents 1 to 5, the above effect is described.
However, in recent years, there is an increasing demand for wireless LAN devices to communicate with a large number of clients. Along with this, a wireless LAN device capable of many settings called multi-SSID has been developed. However, when a new wireless LAN device is replaced with a multi-SSID, there is a problem that a communication network with a new client cannot be constructed only by copying all communication parameter settings.
That is, there is a demand not only to arrange a new wireless LAN device in an existing communication network but also to construct a new communication network while replacing the new wireless LAN device.

  An object of the present invention is to replace a wireless LAN device and / or add a wireless LAN, a wireless LAN device capable of constructing a new communication network as well as an existing communication network, a program for the wireless LAN device, and It is to provide a method for controlling a wireless LAN device.

(1)
A wireless LAN device according to one aspect is a wireless LAN device capable of wireless communication, a request unit that requests a communication parameter by a predetermined operation, and a reception unit that receives a communication parameter transmitted in response to a request from the request unit And a recording unit that records the communication parameter, and a setting unit that sets the communication parameter, and the recording unit includes a first recording area that records the first communication parameter among the communication parameters received by the receiving unit; And a second recording area for recording the second communication parameter among the communication parameters.

In the present invention, the communication parameter is requested by the requesting unit by a predetermined operation. The communication parameter transmitted in response to the request from the requesting unit is received by the receiving unit. The communication parameter is recorded by the recording unit. Communication parameters are set by the setting unit.
The recording unit includes a first recording area for recording the first communication parameter among the communication parameters received by the receiving unit, and a second recording area for recording the second communication parameter among the communication parameters.

In this case, the existing communication parameter requested and transmitted to the other wireless LAN device by the requesting unit of the wireless LAN device is received by the receiving unit and recorded in the first recording area. As a result, the wireless LAN device according to the present invention uses the first recording area to reliably copy the existing communication parameters from the old wireless LAN device, and to maintain the existing network normally, while performing the second recording. Using the area, a new network can be easily constructed.
That is, in the storage area of the new wireless LAN device, not only the communication parameter setting information of the existing wireless LAN device is completely copied, but also a second recording area is provided, and a new wireless LAN communication parameter is set. By recording, a new communication network can be added. As a result, it is possible to cope with the replacement of the wireless LAN device in the case of multi-SSID and the extension of the communication network.
Therefore, since a wireless LAN that simply copies existing communication parameters does not have the second recording area, it has not been possible to set new communication parameters. In the wireless LAN device according to the present invention, this problem can be solved.

(2)
The wireless LAN device according to a second aspect of the present invention may further include a copy button in the wireless LAN device according to one aspect, and the predetermined operation may be a press operation of the copy button.

In this case, the first communication parameter can be easily stored in the first recording area by the copy button.
The copy button may have other functions after the first communication parameter is recorded in the first recording area. For example, an arbitrary function such as a function of shifting to a power saving mode, a USB removal function, a filtering on / off function, etc., may be provided by pressing the button multiple times.

(3)
A wireless LAN device according to a third aspect of the invention is the wireless LAN device according to one aspect or the second aspect of the invention, further including a QR code (registered trademark), wherein the QR code is a second communication parameter in the second recording area. May be displayed.

  In this case, since the wireless LAN device has the second recording area for recording the communication parameter recorded in the QR code, a new network can be easily constructed.

A network can be formed.

(4)
According to a fourth aspect of the present invention, in the wireless LAN device according to the third aspect of the invention from one aspect, when the first communication parameter is recorded in the first recording area, the requesting unit communicates with the receiving unit. The apparatus that has transmitted the parameter may be requested to delete the communication parameter.

In this case, the wireless LAN device can be easily replaced. That is, by disposing the wireless LAN device according to the present invention instead of the wireless LAN device in the existing communication network, it is possible to prevent communication failure of existing clients. That is, it is possible to eliminate the problem of which wireless LAN device a client in an existing communication network should communicate with.
Note that the user can also solve the problem by turning off the power of the existing wireless LAN device.

(5)
According to a fifth aspect of the present invention, in the wireless LAN device according to the third aspect of the present invention from the one aspect, the request unit determines whether the communication of the device that has transmitted the communication parameter to the receiving unit has been lost for a predetermined time. If the first communication parameter is determined to be lost, communication using the first communication parameter may be enabled.

In this case, it can be determined that it has disappeared for a predetermined time, that is, the power of the apparatus has been cut off. As a result, communication duplication can be prevented.
Further, in this case, the first communication parameter can be validated in the first recording area, and further, the first communication parameter is recorded in the first recording area, and then the determination is performed, The first communication parameter recorded in the recording area may be validated to enable communication.

(6)
A wireless LAN device according to a sixth aspect of the invention is the wireless LAN device according to the fifth aspect of the invention based on one aspect. After the predetermined operation, the recording unit determines whether there is a recordable area in the first recording area. May be determined.

  In this case, when a communication parameter is already recorded in the first recording area, a communication error unintended by the user can be prevented by notifying. Therefore, it is possible to reliably record communication parameters in an invalid area (free area). Here, the invalid area refers to a state in which the communication parameters set in the first recording area and the second recording area of the wireless LAN device are deleted, or the first recording unit of the wireless LAN apparatus 100, the first 2 The wireless LAN device 100 has a flag for switching between valid and invalid with respect to the communication parameter set in the recording unit, the communication parameter is used for communication when the valid flag is set, and is not used for communication when the invalid flag is set. In the case of “invalid flag”.

(7)
In the wireless LAN device according to the seventh aspect of the invention, when the power is turned on or reset, the requesting unit and the receiving unit may determine the presence / absence of communication based on communication parameters used for communication.

In this case, since it is determined whether or not communication parameters used by itself are already used, it is possible to prevent an initial communication error.
In addition, the communication parameter used by itself for communication is a communication parameter in a state where a communication parameter (SSID or the like) preset as a default value by the wireless LAN device 100 is pasted or attached to the device as a QR code. Means communication parameters manually set by the user for the wireless LAN device 100, and communication parameters copied from another wireless LAN device by using the present invention (used in other wireless LAN devices) To do.
In addition, it is actually communicable (when the valid or invalid flag can be set and set to valid), and is recorded in each recording unit but is not communicable (the valid or invalid flag is set). Including those that are disabled).

(8)
A wireless LAN device program according to another aspect is a wireless LAN device program capable of wireless communication, a request process for requesting a communication parameter by a predetermined operation, and a communication parameter transmitted in response to a request by the request process Receiving processing, recording processing for recording communication parameters, and setting processing for setting communication parameters, and the recording processing records the first communication parameter among the communication parameters received by the receiving processing. 1 recording area and a second recording area for recording the second communication parameter among the communication parameters.

In the present invention, the communication parameter is requested by a predetermined operation by the request process. The communication parameter transmitted in response to the request processing request is received by the reception processing. Communication parameters are recorded by the recording process. Communication parameters are set by the setting process.
The recording process includes a first recording area for recording the first communication parameter among the communication parameters received by the receiving process, and a second recording area for recording the second communication parameter among the communication parameters.

In this case, the requesting unit of the wireless LAN device requests another wireless LAN device, and the transmitted communication parameter is received by the receiving unit and recorded in the first recording area. As a result, the wireless LAN device according to the present invention uses the first recording area to reliably copy the communication parameters from the old wireless LAN apparatus, and to maintain the existing network normally, while maintaining the second recording area. By using it, a new network can be easily constructed.
In other words, in the storage area of the new wireless LAN device, not only the communication parameter setting information of the old wireless LAN device is completely copied, but also a second recording area is provided so that the communication parameter for the new wireless LAN can be set. By recording, a new communication network can be added. As a result, it is possible to cope with the replacement of the wireless LAN device in the case of multi-SSID and the extension of the communication network.
Therefore, since a wireless LAN that simply copies existing communication parameters does not have the second recording area, it has not been possible to set new communication parameters. In the wireless LAN device according to the present invention, this problem can be solved.

(9)
A control method for a wireless LAN device according to still another aspect is a control method for a wireless LAN device capable of wireless communication, a request step for requesting communication parameters by a predetermined operation, and transmission in response to a request by the request step Including a receiving step for receiving the communication parameter, a recording step for recording the communication parameter, and a setting step for setting the communication parameter, wherein the recording step is a first communication parameter among the communication parameters received by the receiving step.

The communication parameter transmitted in response to the request of the request process is received by the reception process. The communication parameter is recorded by the recording process. Communication parameters are set by the setting process.
The recording step includes a first recording area for recording the first communication parameter among the communication parameters received by the receiving step, and a second recording area for recording the second communication parameter among the communication parameters.

In this case, the requesting unit of the wireless LAN device requests another wireless LAN device, and the transmitted communication parameter is received by the receiving unit and recorded in the first recording area. As a result, the wireless LAN device according to the present invention uses the first recording area to reliably copy the communication parameters from the old wireless LAN apparatus, and to maintain the existing network normally, while maintaining the second recording area. By using it, a new network can be easily constructed.
In other words, in the storage area of the new wireless LAN device, not only the communication parameter setting information of the old wireless LAN device is completely copied, but a second recording area is provided to record the communication parameters for the new wireless LAN device. By doing so, a new communication network can be added. As a result, it is possible to cope with the replacement of the wireless LAN device in the case of multi-SSID and the extension of the communication network.
Therefore, since a wireless LAN that simply copies existing communication parameters does not have the second recording area, it has not been possible to set new communication parameters. In the wireless LAN device according to the present invention, this problem can be solved.

(This embodiment)
FIG. 1 is a schematic perspective view showing an example of the appearance of the wireless LAN device 100 according to the present embodiment. FIG. 2 is a schematic diagram showing an internal configuration of an example of the wireless LAN device 100 according to the present embodiment. It is.

As illustrated in FIGS. 1 and 2, the wireless LAN device 100 includes a transmission unit 200, a reception unit 300, a setting unit 400, a power supply unit 450, a recording unit 500, a copy button 610, and a QR code information unit 620.
As shown in FIG. 2, the recording unit 500 according to the present embodiment includes a first recording unit 510 and a second recording unit 520.

  The copy button 610 is provided on the housing of the wireless LAN device 100. In the QR code information unit 620, a seal printed with a QR code is attached to the back surface of the housing in FIG.

  Next, a specific example when the wireless LAN device 100 according to the present embodiment is used will be described. FIG. 3 is a schematic diagram for explaining a communication network environment by an existing wireless LAN device 700, and FIG. 4 is a schematic diagram showing a case where the wireless LAN device 100 according to the present invention is added to an existing communication network. FIG. 5 is a schematic diagram showing a case where a new communication network is added in the wireless LAN device 100.

FIG. 6 is a time chart when the wireless LAN device 100 according to the present invention is added to an existing communication network, and FIG. 7 is a case of constructing a new communication network of the wireless LAN device 100 according to the present invention. It is a time chart figure.
8, FIG. 9, and FIG. 10 are flowcharts showing an example of the processing in FIG.

First, the communication network shown in FIG. 3 is constructed by an existing wireless LAN device 700 and clients 710 and 720.
Here, the existing wireless LAN device 700 performs, for example, wireless communication conforming to the IEEE 802.11 standard with the clients 710 and 720. Therefore, the existing wireless LAN device 700 includes an SSID (Service Set Identifier), WPA (Wi-Fi Protected Access), encryption key, authentication included in the WPS (Wi-Fi Protected Setup). Communication parameters necessary for wireless communication such as a method and an authentication key are set.

  For example, as shown in FIG. 3, the existing wireless LAN device 700 is set such that the SSID of the existing communication network is OLDSSID and the encryption is B1.

Subsequently, as shown in FIG. 4, when the wireless LAN device 100 according to the present invention is arranged in an existing communication network, the power supply of the wireless LAN device 100 is input. Thereby, the initial processing shown in FIG. 6 is performed.
Hereinafter, the flow of the initial process will be described.

FIG. 8 is a flowchart showing an example of the initial processing shown in FIG.
As shown in FIG. 8, the wireless LAN device 100 performs power-on or reset recognition (step S1).
Subsequently, the wireless LAN device 100 determines whether there is a communication parameter that can be used by the wireless LAN device 100 (step S2). Here, when it is determined that there is no communication parameter (No in step S2), the initial process is terminated.
On the other hand, when it is determined that there is a communication parameter that can be used by itself (Yes in step S2), it is determined whether or not there is a wireless master device that uses the communication parameter used by itself (step S3).

Here, communication parameters that can be used by the user will be described. In the present embodiment, as shown in FIG. 4, the wireless LAN device 100 is compatible with multi-SSID. The wireless LAN device 100 has, for example, SSID_A, SSID_B, and SSID_C.
In addition, the wireless LAN device 100 has default values of communication parameters associated with a sticker printed with a QR code described in the QR code information unit 620 attached to the back surface of the main body. Therefore, SSID_A is the default SSID of the communication parameter, SSID_B is UserSSID, which is a communication parameter manually set by the user, and SSID_C is invalid (empty).

  In this embodiment, SSID_C is invalid (empty). However, for example, the wireless LAN device 100 has already copied communication parameters from a wireless master device such as the wireless LAN device 700, and the communication parameters are set as SSID_C. It may be set and communicateable.

  In the present embodiment, since there are communication parameters that can be used as an operation when the wireless LAN device 100 is turned on, the process proceeds to the process of step S3 after the process of step S2, and the communication parameters used by itself are set. Check if there is another wireless master unit used.

  For example, the confirmation can be confirmed by receiving a signal including SSID information using a beacon (beacon) transmitted from another wireless master device.

  As a specific example of the process of step S3, the wireless LAN device 100 confirms the presence of communication by another parent device using communication parameters that can be set as SSID_A and SSID_B.

  Next, when it is determined by the confirmation that there is no other wireless master device using the communication parameter used by itself (No in step S3), the wireless LAN device 100 sets SSID_A and SSID_B to itself, The communication is ready.

  On the other hand, if it is determined by the confirmation that there is another wireless master device that uses the communication parameter used by itself (Yes in step S3), the wireless LAN device 100, for example, uses another wireless master device that uses SSID_B. If there is a machine, the presence of the machine is notified by an LED or sound (step S4). And the process of step S3 and the process of step S4 are repeated until it does not exist.

  At that time, the corresponding communication parameter (SSID_B in the above case) may be set to “invalid”. In this case, it is possible to perform communication using communication parameters (for example, default values) that can be communicated while notifying that “there are other wireless master units using communication parameters used by itself”. Good.

  Finally, communication of communication parameters SSID_A and SSID_B determined not to exist is enabled (step S5). Thus, the initial process of the wireless LAN device 100 is finished.

  As a result, for example, when the user mistakenly sets the same communication parameter for another wireless master unit or the communication parameter has been copied from another wireless master unit, the user and another wireless master device When the power of the parent device (communication parameter copy source) is turned on, duplication of communication parameters can be prevented.

Subsequently, as shown in FIG. 6, the copy button 610 of the wireless LAN device 100 is pressed.
Further, a WPS button provided in advance in the existing wireless LAN device 700 is pressed.
In this case, as shown in FIG. 6, the wireless LAN device 100 performs an area determination process and then waits for a request by WPS.

  Next, the area determination process in FIG. 6 will be described. FIG. 9 is a flowchart illustrating an example of the area determination process of FIG.

  As shown in FIG. 9, the wireless LAN device 100 determines whether there is an invalid area in the storage area after the copy button 610 is pressed (step S11).

If there is an invalid area (Yes in step S11), for example, if SSID_A is Default SSID, encrypted A1, SSID_B is UserSSID, encrypted B1, and SSID_C is invalid, the invalid area is Since it is determined, the region determination process is terminated.
The Default SSID and encryption A1 are communication parameters of the wireless LAN device 100 itself, and are information on a seal on which a QR code of the QR code information unit 620 attached to the wireless LAN device 100 is printed.

  If there is no invalid area (No in step S11), for example, SSID_A is Default SSID, encryption A1, SSID_B is User SSID, encryption B1, SSID_C is oldSSID, and encryption is performed. In the case of C1, since there is no invalid area, notification is made using an LED or sound (step S12). As a result, the user can recognize that there is no invalid area.

  Subsequently, it is determined whether or not a predetermined operation has been performed within a predetermined time (step S13). If it is determined not to be implemented (No in step S13), the process is terminated without copying (step S14). Therefore, it is possible to prevent erroneously overwriting important communication parameters that have already been set.

  On the other hand, when it is determined that a predetermined operation has been performed (Yes in step S13), the copy area is set to be invalid (step S15). That is, some or all of the predetermined SSID is invalidated. For example, one or both of SSID_B and SSID_C are invalidated.

In addition, the predetermined operation is, for example, an operation that is arbitrarily determined in advance, such as “simultaneous pressing of the WPS button and the copy button within 5 seconds”, “long pressing of the WPS button or the copy button for 2 seconds or more” It is.
In the case where one of SSID_B and SSID_C is invalidated, the priority order to be invalidated may be determined by a predetermined operation, for example, the number of times the copy button is pressed.
Furthermore, when there is no access for a predetermined period of time between SSID_B and SSID_C, the communication parameter may be automatically changed to invalid.

  The determination as to whether there is no access for a predetermined period or more may be made by the wireless LAN device 100 holding its own communication history and confirming the stored information.

Next, as illustrated in FIG. 6, a signal requesting wireless LAN setting information is transmitted from the transmission unit 200 of the wireless LAN device 100 to the existing wireless LAN device 700.
Although not described in the present embodiment, a request signal or a beacon is transmitted from the wireless LAN device 100 to the existing wireless LAN device 700 in advance, and the wireless LAN device 100 receives a response to the transmission. It may be.

  In addition, the existing wireless LAN device 700 may not be provided with a button related to WPS, and may automatically respond to a signal requested by the wireless LAN device 100.

Next, as shown in FIG. 6, the existing wireless LAN device 700 receives the requested signal and transmits wireless LAN setting information including WPS related to the existing communication network to the wireless LAN device 100.
Specifically, it transmits that the SSID of the existing communication network is the Old SSID and the encryption is C1.

When receiving the wireless LAN setting information from the existing wireless LAN device 700, the wireless LAN device 100 transmits a signal indicating that the wireless LAN setting information has been received to the existing wireless LAN device 700.
Subsequently, as illustrated in FIG. 6, the wireless LAN device 100 performs pre-setting processing.

FIG. 10 is a flowchart illustrating an example of the pre-setting process in FIG.
As shown in FIG. 10, the wireless LAN device 100 determines whether there is a wireless master device that uses the communication parameters acquired from the existing wireless LAN device 700 (step S21).
That is, the process of step S21 is a process for preventing the same communication parameter from being duplicated.

  For example, the confirmation can be confirmed by receiving a signal including SSID information using a beacon (beacon) transmitted from another wireless master device.

  Here, for example, when it is determined by the processing in step S21 that there is another wireless master device using the communication parameter acquired from the existing wireless LAN device 700 (Yes in step S21), that is, the existing wireless When the LAN device 700 itself still exists, the fact that it exists is notified by an LED or sound (step S22). And it waits until communication of the existing wireless LAN apparatus 700 which is the said wireless main | base station lose | disappears.

  On the other hand, when it is determined that the wireless master device does not exist (No in step S21), the setting unit 400 of the wireless LAN device 100 stores the wireless LAN setting information in the first recording of the recording unit 500 as illustrated in FIG. The setting is made on the basis of the received wireless LAN setting information while being recorded in the unit 510.

  Specifically, as illustrated in FIG. 4, the wireless LAN device 100 sets the Old SSID and the encryption C1 to SSID_C included in the WPS.

  As a result, as shown in FIG. 4, the wireless LAN device 100 can perform wireless communication with the clients 710 and 720.

Next, as illustrated in FIG. 5, the wireless LAN device 100 constructs a new communication network with the clients 730, 740, 750, and 760.
In this case, the communication settings of the clients 730, 740, 750, and 760 can be performed using a sticker printed with a QR code described in the QR code information section 620 of the wireless LAN device 100 as shown in FIG. .
For example, the wireless LAN setting information can be set by reading a QR code with a barcode scanner or a camera.

  Here, when the wireless LAN device 100 does not have a plurality of SSIDs (hereinafter referred to as multi-SSIDs) SSID_A, SSID_B, and SSID_C and constructs a new communication network, the QR code attached to the wireless LAN device 100 is: It is unique to the wireless LAN device 100, and it is necessary to confirm QR code information unique to the existing wireless LAN device 700.

  Therefore, for example, when the existing wireless LAN device 700 is outdated, when the wireless LAN device 100 is replaced, the existing wireless LAN device 700 is often discarded. In this case, regarding the clients 710 and 720, it is necessary to set again by manual work, which is troublesome.

  However, in the wireless LAN device 100 according to the present invention, since the WPS information of the existing communication network is recorded in the first recording unit 510 of the recording unit 500, no problem occurs, and the second recording unit 520 is included in the QR code. Since the WPS information of the communication network is recorded, a new communication network can be easily constructed.

Subsequently, as shown in FIG. 5, in the new communication network, it can be set that the SSID_A is the Default SSID and the initial value of the encryption is A1 for the clients 730 to 760.
In the present embodiment, the communication is set from the SSID that is the WPS information recorded in the QR code information unit 620. However, the present invention is not limited to this, and the clients 730 to 760 are connected to the personal computer. In some cases, the setting may be performed using a mouse or a keyboard.

  Furthermore, when the clients 730,..., 760 are mobile communication terminals or game machines, communication settings can be easily performed by imaging a QR code.

  Note that a signal for deleting the WPS information of the existing wireless LAN device 700 may be transmitted from the wireless LAN device 100 before the wireless LAN device 100 of FIG. 6 and the clients 710 and 720 communicate with each other.

As described above, a request from the transmission unit 200 of the wireless LAN device 100 is requested to the existing wireless LAN device 700, and the transmitted communication parameter is received by the reception unit 300 and recorded in the first recording unit 510. As a result, the wireless LAN device 100 according to the present invention can easily construct a new network while reliably copying the communication parameters from the existing wireless LAN device 700 and maintaining the existing network normally.
That is, since the new wireless LAN device 100 does not copy the communication data of the existing wireless LAN device 700 as it is, a new network can be added to the new wireless LAN device 100. As a result, multi-SSID can also be supported.

  Further, the communication parameters of the existing communication network can be easily stored in the first recording unit 510 by the copy button.

Furthermore, since the communication parameters in the second recording unit 520 are displayed in the QR code, a new communication network can be easily formed.

  In the present invention, the wireless LAN device 100 corresponds to a “wireless LAN device”, the transmission unit 200 corresponds to a “request unit”, the reception unit 300 corresponds to a “reception unit”, and the recording unit 500 corresponds to a “recording unit”. The setting unit 400 corresponds to the “setting unit”, the first recording unit 510 corresponds to the “first recording area”, and the second recording unit 520 corresponds to the “second recording area”. , OldSSID is equivalent to “first communication parameter”, DefaultSSID is equivalent to “second communication parameter”, copy button 610 is equivalent to “copy button”, and existing wireless LAN device 700 is The QR code information unit 620 corresponds to the “QR code”.

  A preferred embodiment of the present invention is as described above, but the present invention is not limited thereto. It will be understood that various other embodiments may be made without departing from the spirit and scope of the invention. Furthermore, in this embodiment, although the effect | action and effect by the structure of this invention are described, these effect | actions and effects are examples and do not limit this invention.
