Description

The present invention relates to a wireless relay device and a control method, and particularly to a wireless connection.

In recent years, as one form of constructing a wireless LAN (Local Area Network), an infrastructure method for wirelessly connecting a wireless relay device (access point) and one or more wireless terminals (laptop, tablet, smartphone, etc.) has been used. A communication system is built.

A general method of assigning a wireless terminal to a wireless relay device is a method in which a user operates the wireless terminal, selects a wireless relay device, and inputs connection information such as an encryption key. The connection information (also referred to as a wireless parameter) is, for example, an SSID (Service Set Identity), an encryption key, or an identifier for identifying each wireless relay device when a plurality of wireless relay devices are present in the surrounding area. Information related to security in wireless communication such as passwords.

However, the work of setting various connection information requires some knowledge of wireless LAN, which is troublesome for the user.

Therefore, a WPS (Wi-Fi (registered trademark) Protected Set) function is known as a function of reducing this time and effort and easily assigning a wireless terminal to a wireless relay device. As a method of making a wireless connection by the WPS function, for example, a PBC (Push Button Configuration) method is known in which a button (switch) provided on both a wireless relay device and a wireless terminal is pressed within a certain period of time.

In the WPS function, wireless parameters are provided from the wireless relay device to the wireless terminal by using a special protocol (called a Migration protocol) for wireless parameter setting processing.
Specifically, communication between the wireless relay device and the wireless terminal in the Regency protocol is performed using a packet EAP (Extensible Authentication Protocol) packet that enables communication between the wireless relay device and the wireless terminal without performing encryption and authentication. It is said. Further, in the PBC method, the wireless connection setting process is started when the push buttons provided on both the wireless relay device and the wireless terminal are pressed. Then, in the wireless connection setting process (hereinafter, also referred to as WPS process), the wireless relay device and the wireless terminal send and receive messages using EAP packets, so that the wireless relay device provides wireless parameters to the wireless terminal. Is done. The wireless terminal sets the wireless parameters provided by the wireless repeater. This makes it possible to perform data communication using encryption and authentication between the wireless relay device and the wireless terminal.

Here, when the PBC method is applied in the above communication system, a problem may occur. For example, the wireless relay device installed in the above communication system is usually installed in a place high from the ground, in the ceiling of a room, and in a wall so that only an administrator can easily touch it. Once installed, it cannot be easily touched. Further, in the case of the button pressing method (PBC method), it cannot be applied when the wireless relay device cannot mount the button due to mechanical restrictions.

In response to such a problem, Patent Document 1 states that the communication device (access point) is another device (for example, an image pickup device, a voice input device, etc.) depending on the detection of a predetermined event. Establishing a wireless connection with (eg a station, etc.) is described.

JP-A-2018-148426

However, the technique described in Patent Document 1 can improve the convenience when executing the wireless connection process by the WPS function, but the wireless network that can be constructed is limited to one. For example, when there are multiple adjacent wireless relay devices, and you want to build each wireless communication (wireless communication between the wireless relay device and multiple wireless terminals under it) as separate wireless networks for security reasons. Has a problem that it cannot be dealt with. Further, in the technique described in Patent Document 1, voice data is generated by performing predetermined voice processing or compression coding processing on the voice signal collected by the voice input device, and an event is detected based on the voice data. However, depending on the environment around the communication device (including noise), the voice data does not always show a constant value, and it may be necessary to set the voice data at each place of use.

The present invention has been made to solve the above problems, and an object of the present invention is to be able to easily set a wireless connection with a communication terminal and to be able to construct a plurality of networks.

The wireless relay device according to one aspect of the present invention is a wireless relay device that performs wireless connection processing with a communication terminal by external voice, and is a wireless communication that notifies the communication terminal of information necessary for authentication processing for wireless communication. A voice input unit that receives an external voice, a storage unit that stores a voice data identification information table and an SSID setting information table, and a voice signal received by the voice input unit are analyzed using the voice data identification information table and voice. A voice signal recognition unit that converts signal data, a communication control unit that controls the wireless communication unit so as to start WPS processing for wireless connection between the communication terminals, and a determination unit that converts voice signal data. The WPS processing start judgment and SSID identification judgment are performed on the character string data by referring to the SSID setting information table, and the character string data converted into voice signal data is used as the WPS processing start condition stored in the SSID setting information table. When a matching character string is included and any SSID stored in the SSID setting information table is included, a determination unit for notifying the communication control unit of the SSID is provided.

According to this, in order to start the WPS processing of the PBC method, the wireless relay device conventionally presses the physical switch (push button) of the wireless relay device and also presses the push button provided on the communication terminal. However, even in a situation where the switch of the wireless relay device cannot be pressed, the WPS process can be easily performed by emitting a voice signal for the user to start the WPS process to the wireless relay device and further emitting the SSID as voice. Can be started and wireless connection processing can be performed.

Further, the determination unit further includes a determination failure count counter, and when the numerical value of the determination failure count counter reaches the SSID determination limit value stored in the SSID setting information table, the SSID identification determination is performed until a certain period of time elapses. You may decide not to do so.

According to this, since the wireless relay device does not start the WPS process by external utterance, unauthorized use of the wireless relay device by an unexpected person is eliminated under certain conditions, which contributes to the improvement of security.

The control method of the wireless relay device according to another aspect of the present invention is a control method of the wireless relay device that performs wireless connection processing with the communication terminal by external voice, and communicates information necessary for authentication processing for wireless communication. Voice data identification of the wireless communication step that notifies the terminal, the voice input step that receives external voice, the storage step that stores the voice data identification information table and the SSID setting information table, and the voice signal received by the voice input unit. In the voice signal recognition step that analyzes using the information table and converts the voice signal data, the communication control step that controls the wireless communication unit so as to start the WPS processing for wireless connection with the communication terminal, and the determination step. Therefore, for the character string data converted into voice signal data, the WPS processing start judgment and the SSID identification judgment are performed with reference to the SSID setting information table, and the character string data converted into voice signal data is stored in the SSID setting information table. When a character string matching the stored WPS processing start condition is included and any SSID stored in the SSID setting information table is included, a determination step of notifying the communication control step of the SSID is included.

According to this, the control method has the same effect as that of the wireless relay device.

The wireless relay device according to the present invention can easily set a wireless connection with a communication terminal, and further enables the construction of a plurality of networks.

As shown in FIG. 3, the wireless relay device 1 includes a voice input unit 31, a voice signal recognition unit 32, a storage unit 33, a determination unit 34, a communication control unit 35, and a wireless communication unit 36. .. Further, the storage unit 33 includes a voice data identification information table 331 and an SSID setting information table 332.

The voice input unit 31 determines whether or not the voice (external voice) emitted by the user has been input as a voice signal (whether or not it has been accepted). Therefore, it is desirable that the voice input unit 31 can distinguish between ambient noise and human utterance. When the voice input unit 31 receives the voice signal, the voice input unit 31 notifies the voice signal recognition unit 32 of the voice signal and temporarily stores the voice signal in the memory (for example, RAM 22). When the voice input unit 31 receives the external voice, if there is a certain blank time (for example, 500 ms) between one external voice and the next received external voice, the voice input unit 31 is different from each other. May be recognized and notified to the voice signal recognition unit 32.

The voice input unit 31 is realized by the CPU 20, ROM 21, RAM 22, voice input IF 26, and the like.

The audio signal recognition unit 32 analyzes the audio signal and converts the audio signal into character string data (also referred to as audio signal data conversion). Here, various processing methods can be considered for the audio signal data conversion process. For example, the conversion process converts (samples) an analog signal into a digital signal and performs arithmetic processing (for example, Fourier transform). Is performed, and it is analyzed and converted into data according to the type of sound (for example, vowel, consonant, etc.). Then, the voice signal recognition unit 32 converts the voice signal into character data by referring to the analyzed data and the voice data identification information table 331 previously stored in the storage unit 33. Specifically, the voice signal recognition unit 32 uses the voice signal notified from the voice input unit 31 as character string data (character string data A) and SSID name candidates that are candidates for conditions for starting WPS processing. The voice signal data is converted into the character string data (character string data B). The voice signal recognition unit 32 may collectively convert the signals notified by the voice input unit 31 into voice signal data. Alternatively, from the voice signal notified from the voice input unit 31, the character string data A which is a candidate for the condition for starting the WPS processing and the character string data B which is a candidate for the SSID name are separated as two character string data B. It may be possible to convert.

The audio signal recognition unit 32 is realized by the CPU 20, ROM 21, RAM 22, storage device 23, and the like.

The storage unit 33 includes a voice data identification information table 331 and an SSID setting information table 332. In addition, the storage unit 33 stores setting information related to various devices. For example, MAC (Media Access Control) address, channels that can be used for wireless communication, authentication information (radio parameters for WPS processing, etc.), and various other information related to control (depending on the specifications of the wireless relay device 1). Store.

The storage unit 33 is realized by a ROM 21, a RAM 22, a storage device 23, and the like.

The voice data identification information table 331 stores information necessary for converting a voice signal into character string data. For example, it is information that is used as a dictionary for voice recognition. Specifically, it is a database of acoustic models, language models, pronunciation dictionaries, etc. of dictionaries in specialized fields (daily life, medical care, finance, office, etc.).

The SSID setting information table 332 stores character string data (also referred to as a WPS processing start condition) that is a condition for starting WPS processing. Further, the SSID setting information table 332 stores a plurality of SSIDs (stored as character string data). Further, the SSID setting information table 332 stores the SSID determination limit value (hereinafter, will be described in detail with reference to FIG. 5).

In the SSID setting information table 332, the character string data and the SSID character string data, which are the conditions for starting the WPS processing, may be set in advance by the user using a dedicated tool or the like, or are set at the time of shipment from the factory. May be good.

In the determination unit 34, does the character string data A converted into voice signal data by the voice signal recognition unit 32 match the character string data stored in the SSID setting information table 332, which is a condition for starting WPS processing? Whether or not it is determined (hereinafter, also referred to as WPS processing start determination). If the determinations match, the determination unit 34 notifies the communication control unit 35 to that effect.

Further, in the determination unit 34, the character string data B converted into voice signal data by the voice signal recognition unit 32 matches the character string data of any one of the plurality of SSIDs stored in the SSID setting information table 332. Whether or not it is determined (also referred to as SSID identification determination). When the character string data matches, the determination unit 34 notifies the communication control unit 35 of the matched character string data (that is, the character string data of any one of the plurality of SSIDs). The matched character string data may be stored in the storage unit 33 temporarily or for a certain period of time. For example, even if the terminal device used by the user is temporarily disconnected from the wireless relay device 1 (for example, due to deterioration of the wireless environment), if the same user wants to reconnect, the same terminal device is used. If so, the wireless connection process can be started without external voice.

Further, the determination unit 34 includes a determination failure count counter that counts the number of failures in the SSID identification determination process. Specifically, the initial value of the determination failure count counter is 0 (zero), and the value is incremented by 1 when the SSID identification determination process does not match any of the SSIDs stored in the SSID setting information table 332. And store it in memory. The determination unit 34 determines whether or not the numerical value of the determination failure count counter has reached the SSID determination limit value stored in the SSID setting information table 332. When the SSID determination limit value is reached, the determination unit 34 may not perform the SSID identification determination process until a certain period of time (for example, 30 minutes) has elapsed, and the determination unit 34 may not perform the SSID identification determination process for a certain period of time (for example, 30 minutes). After that, it may be reset to the initial value. By doing so, since the wireless relay device 1 does not start the WPS process by external utterance, the security against unauthorized use of the wireless relay device 1 by an unexpected person is improved.

The determination unit 34 is realized by the CPU 20, ROM 21, RAM 22, storage device 23, and the like.

The communication control unit 35 receives a notification from the determination unit 34 that the character string data A converted into voice signal data and the character string data that is a condition for starting the WPS processing match, and further, the identification determination is performed. When the completed SSID is received, the wireless communication unit 36 is notified to start the WPS process for wireless connection between the communication terminal 2 or the wireless terminal 5 and the wireless relay device 1 based on the SSID. ..

The communication control unit 35 is realized by a CPU 20, a ROM 21, a RAM 22, a storage device 23, and the like.

The wireless communication unit 36 performs wireless communication with the communication terminal 2 or the wireless terminal 5.

The wireless communication unit 36 performs WPS processing with the communication terminal 2 or the wireless terminal 5 based on the notification of the communication control unit 35, so that the information required for the authentication process for wireless communication (for example, SSID) , Authentication method, encryption method, etc.).

The wireless communication unit 36 is realized by a CPU 20, a ROM 21, a RAM 22, a storage device 23, a WNIC 24, and the like.

Next, FIG. 4 describes step by step the process from the reception of the external voice by the wireless relay device 1 according to the embodiment of the present invention to the start of the WPS process with the communication terminal 2 and the wireless terminal 5.

In FIG. 4, the wireless relay device 1 according to the embodiment of the present invention receives a voice signal (external voice) from each user in order for the communication terminal 2 and the wireless terminal 5 to make a wireless connection, respectively, and also receives the voice signal. A case where WPS processing is started with the communication terminal 2 through the communication link 7 and WPS processing with the wireless terminal 5 is started through the communication link 8 to make a wireless connection with both communication links will be described.

In step S41, it is determined whether or not the numerical value of the determination failure count counter has reached the SSID determination limit value stored in the SSID setting information table 332. When the determination failure count counter reaches the SSID determination limit value, the determination unit 34 ends the process (Yes in step S41). On the other hand, when the determination failure count counter has not reached the SSID determination limit value, the determination unit 34 transitions to step S42 (No in step S41). Here, the value of the determination failure count counter may be reset to the initial value after a certain period of time (for example, 30 minutes) has elapsed.

In step S42, the voice input unit 31 determines whether or not the voice (external voice) emitted by the user has been input as a voice signal (whether or not it has been received). When the voice input unit 31 receives the voice signal, the voice input unit 31 notifies the voice signal recognition unit 32 of the voice signal (Yes in step S42). On the other hand, when the voice input unit 31 has not received the voice signal, the voice input unit 31 repeats step S42 (No in step S42).

In step S43, the voice signal recognition unit 32 analyzes the voice signal notified in step S42, converts the voice signal data, and notifies the determination unit 34 of the converted character string data. Here, the character string data notified to the determination unit 34 includes the character string data A which is a candidate for the condition for starting the WPS processing and the character string data B which is a candidate for the SSID name individually or simultaneously.

In step S44, the determination unit 34 includes the character string data A notified in step S43 and the character string data (WPS processing start condition) that is a condition for starting WPS processing stored in the SSID setting information table 332. Determine if they match. If the character string data match, the determination unit 34 notifies the communication control unit 35 to that effect (Yes in step S44). On the other hand, if the character string data do not match, the determination unit 34 returns to step S42 and waits until the audio signal is input (No in step S44).

In step S45, the determination unit 34 refers to the SSID setting information table 332, and is stored in the character string data B (character string data that is a candidate for the SSID name) notified in step S43 and the SSID setting information table 332. It is determined whether or not any one of the plurality of SSIDs matches. When the character string data matches, the determination unit 34 notifies the communication control unit 35 of the matched character string data (that is, the character string data of any of the plurality of SSIDs) (Yes in step S45). On the other hand, if the character string data do not match, the determination unit 34 transitions to step S49 (No in step S45).

In step S46, the communication control unit 35 notifies that the character string data A notified in step S43 matches the character string stored in the SSID setting information table 332 as a condition for starting WPS processing. Upon receiving (Yes in step S45), WPS processing for wireless connection is executed between the communication terminal 2 or the wireless terminal 5 and the wireless relay device 1 based on the SSID notified in step S45. Specifically, when the SSID notified in step S45 is SSID1 (for example, Eigyou in FIG. 5 described later), the communication control unit 35 notifies the wireless communication unit 36 to that effect and transitions to step S47. To do. If the SSID notified in step S45 is SSID2 (for example, Gesuto in FIG. 5 described later), the communication control unit 35 notifies the wireless communication unit 36 to that effect and proceeds to step S48.

In step S47, the wireless communication unit 36 sends information necessary for authentication processing for wireless communication toward the communication terminal 2 that is going to perform WPS processing according to the determination that the SSID notified in step S46 is SSID1. Notify (for example, SSID1, authentication method, encryption method, etc.).

In step S48, the wireless communication unit 36 sends information necessary for authentication processing for wireless communication toward the wireless terminal 5 that is going to perform WPS processing according to the determination that the SSID notified in step S46 is SSID2. Notify (for example, SSID2, authentication method, encryption method, etc.).

Here, regarding the WPS processing in steps S47 and S48, for example, the user of the communication terminal 2 or the wireless terminal 5 starts the wireless relay device 1 and the WPS processing by pressing the push button provided on the terminal device. Can be done.

As described above, in order to start the WPS processing of the PBC method, it has been conventionally necessary to press the switch 27 of the wireless relay device 1 and also press the push button provided in the communication terminal 2 or the wireless terminal 5. Even in a situation where the switch 27 of the wireless relay device 1 cannot be pressed, the WPS process can be easily started by transmitting an audio signal for the user to start the WPS process to the wireless relay device 1. In step S49, the determination unit 34 increments the determination failure count counter value by 1, and returns to step S41.

An example of the SSID setting information table 332 according to the embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 5, the SSID setting information table 332 includes WPS processing start condition 51, SSID 52, SSID determination limit value 53, and the like for each item.

The WPS processing start condition 51 indicates a character string that triggers the wireless relay device 1 to start the WPS processing for wirelessly connecting to the communication terminal 2 or the wireless terminal 5.

The SSID 52 includes a plurality of SSIDs that are identifiers for identifying the wireless relay device 1. Each SSID is used when constructing a different network.

The SSID determination limit value 53 indicates a limit value for accepting external utterances. In the embodiment of the present invention, the wireless relay device 1 accepts an external utterance when the determination failure count counter value reaches the SSID determination limit value, but does not start the WPS process.

Further, in the SSID setting information table 332, (1) the character string of the WPS start condition 51 is the same for a plurality of SSIDs, or (2) the character string of the WPS disclosure condition 51 also serves as the character string of the SSID 52. The character string data A may be used as the character string data B for the determination. In this case, the level of security is slightly lowered, but there is an advantage that the user can easily memorize the parameters for connection.

As described above, the wireless relay device 1 according to the embodiment of the present invention can restrict the user from executing the WPS process by the combination of each item provided in the SSID setting information table 332. For example, normally, a user who has permission to use the wireless relay device 1 knows the character string 51 and SSID 52 of the WPS processing start condition of the wireless relay device 1 to be used, so that the number of times (preferably as few as possible) is predetermined. You should be able to perform WPS processing within). On the other hand, in the communication system 100, it is avoided that the WPS process is executed by a malicious person making an external voice to the wireless relay device 1 a plurality of times (the number of times until the WPS process start condition is matched). Therefore, when the SSID determination limit value 53 and the determination failure count counter value match, the wireless relay device 1 does not start the WPS process from the viewpoint of security.

The present invention can be used when it is desired to construct a plurality of networks by using the WPS function for easily setting the wireless connection.
