  However, in a general wireless access point device such as the invention described in Patent Document 1, the value to be set differs depending on the type of the slave unit in which the value of the DTIM interval is described. Therefore, when a plurality of types of child devices are connected to the same SSID, the value of the DTIM interval must be set to the minimum value among the values corresponding to the plurality of types of child devices. Since the power consumption increases as the DTIM interval decreases, more power than necessary may be consumed depending on the type of the slave unit. That is, the power saving effect of the standby power by the POWER-SAVE function cannot be sufficiently exhibited.

  In addition, in a wireless access point device having a multi-SSID function, it is possible to manually set DTIM transmission interval settings, the number of retransmissions, encryption settings, and the like for each SSID. However, unless the user understands the setting of the optimum value according to the type of the slave unit to be connected and distributes the SSID for each type of slave unit, each optimum setting cannot be made.

Embodiment 1. FIG.
FIG. 1 is a block diagram showing a configuration of a first embodiment (embodiment 1) of a communication system including a wireless LAN access point device according to the present invention. FIG. 2 is an explanatory diagram showing optimum setting information of the wireless slave unit. The wireless LAN access point device 22 shown in FIG. 1 includes a setting management unit 25, a wireless slave device determination unit 26, and a connection SSID determination unit 27. The wireless LAN access point device 22 includes an SSID 23 and an SSID 24, and has a multi-SSID function. The wireless LAN access point device 22 communicates with a plurality of types of wireless slave devices such as the mobile phone 20 or the PC 21.

Specifically, the wireless slave device determination unit 26 is realized by the CPU of the wireless LAN access point 22 that operates according to a program, and has a function of determining the type of wireless slave device to be connected. For example, a case is assumed in which the PC 21 performs an easy connection function “Easy Wireless Start (registered trademark)” to establish a connection in order to connect to the wireless LAN access point device 22. When the PC 21 exchanges information of the connection destination by easy wireless start, the wireless slave device determination unit 26 reads the information sent from the PC 21 to determine the type of the wireless slave device.

  Specifically, the connection SSID determination unit 27 is realized by the CPU of the wireless LAN access point device 22 that operates according to a program. The connection SSID determination unit 27 acquires the type of the wireless slave unit determined by the wireless slave unit determination unit 26 and the setting information of the SSID managed by the setting management unit 25 and holds it in FIG. The optimum connection destination is determined in comparison with the information shown. Further, the connection SSID determination unit 27 notifies the setting management unit 25 of the determined SSID.

  Specifically, the setting management unit 25 is realized by the CPU of the wireless LAN access point device 22 that operates according to a program. The setting management unit 25 manages setting information and activation states of SSIDs (SSID 23 and SSID 24 in the example illustrated in FIG. 1). When the optimum SSID notified from the connection SSID determination unit 27 is not activated, the setting management unit 25 may activate the SSID. With this mechanism, since the SSID can be stopped while the wireless slave device to be connected is not connected, the power saving effect of standby power can be obtained.

  The wireless LAN access point device 22 notifies the wireless slave unit of the SSID setting information determined by the connection SSID determination unit 27 so that the wireless slave unit communicates with the determined SSID.

  The operation of the wireless LAN access point device of this embodiment will be described. FIG. 3 is a flowchart showing the operation of the first embodiment of the wireless LAN access point device according to the present invention. FIG. 4 is a sequence diagram showing a communication procedure with the wireless slave device in the first embodiment of the wireless LAN access point device according to the present invention. In the WPS (Wi-Fi Protected Setup) setting in the following description, a push button configuration (PBC) is used, but a PIN (personal identification number) code method may be used, for example.

  When the wireless slave device makes a connection request to the wireless LAN access point device 22, a request (Probe Request) for searching for the corresponding SSID is transmitted from the wireless slave device (step S11, sequence 31). The wireless LAN access point device 22 returns a response (Probe Response) to the wireless slave device from the SSID (SSID 23 in the example shown in FIG. 4) specified in the Probe Request (sequence 32). The wireless slave device transmits an authentication request (Auth Request) to the wireless LAN access point device 22 (sequence 33), and the wireless LAN access point device 22 returns an authentication response (Auth Response) to the wireless slave device (sequence). 34)

  The wireless slave device determination unit 26 reads information such as the MAC address and VendorOption described in the Probe Request, and determines the type of wireless slave device to be connected. The SSID 23 and SSID 24 are set according to the type of the slave unit to be communicated. The setting information and the activation state are managed by the setting management unit 25. When the wireless slave device determination unit 26 determines the type of the wireless slave device, the connection SSID determination unit 27 inquires of the setting management unit 25 about the setting information and activation status of each SSID, and obtains the information.

  The connection SSID determination unit 27 determines an optimum connection destination based on the type of the wireless slave device to be connected and the SSID setting information acquired from the setting management unit 25. Specifically, a table prepared in advance as shown in FIG. 2 in which the type of the wireless slave device and the optimum setting information of the wireless slave device are associated is used. Using this table, the connection SSID determination unit 27 determines that the SSID having the same or closest setting information as the optimal setting information for connecting the wireless slave device is the optimal SSID. Then, the determined SSID is notified to the setting management unit 25.

  The setting management unit 25 determines the activation state of the SSID that has been optimally set notified from the connection SSID determination unit 27 (step S12), and activates the SSID if it has not been activated (step S13). . In the example shown in FIG. 4, since the SSID 24 is the optimal SSID for the wireless slave device that has requested connection, the SSID 24 is activated (sequence 35). When the SSID 24 is activated, information including setting information of the SSID 24 is transmitted as Beacon (sequence 36).

  The connection SSID determination unit 27 notifies the determined SSID and the setting information of the SSID to the wireless slave device (steps S14 and S15), and the wireless LAN access point device 22 and the wireless slave device use the setting information of the SSID 24. To set WPS. (Sequence 37). As a result, in the subsequent communication, the wireless slave device is connected to the SSID 23 using the setting information of the SSID 24 that is optimally set in the wireless slave device.

  Hereinafter, the effect when the various wireless slaves shown in FIG. 2 are used for the wireless LAN access point device 22 will be described. As shown in FIG. 2, for example, when the type of the wireless slave device is a game machine terminal, it is not necessary to maintain the connection between the wireless LAN access point device 22 and the wireless slave device when communication is not being performed. However, if the SSID setting of the communication destination is a setting for maintaining the connection even when communication is not performed, standby power is wasted. Therefore, when a connection request is made from the game machine terminal, the wireless LAN access point device 22 activates the SSID that is set not to maintain the connection when not communicating, and causes the SSID to communicate. Thereby, power consumption in a standby state can be reduced.

  In addition, as shown in FIG. 2, there are various slave units depending on applications such as a slave unit in which speed is important and a slave unit in which packet loss does not occur rather than speed and stable communication is important. . For example, if the type of slave unit, such as a game machine or printer, places importance on stable communication, automatically connect to an SSID that has a high number of retransmissions and is unlikely to be lost at a low rate Thus, stable communication can be performed. Also, for example, mobile phones, TVs, and personal computers such as mobile phones, TVs, and personal computers that are important to speed can be connected to an SSID that is set to output at a high rate by reducing the number of retransmissions. Communication can be performed.

  In addition, for example, there is a child device such as a game machine that does not need to maintain connection during a period in which communication is not performed. By automatically connecting such a slave unit to one SSID, standby power can be saved by extending the DTIM interval at the timing when there is no communication from the slave unit connected to each SSID. An effect is obtained.

  In addition, in a general wireless LAN access point device, there is a problem that it is a burden on the user because it is necessary for the user to make settings after understanding specialized settings such as DTIM settings and retransmission count settings. . In addition, it is necessary to determine which SSID to belong to according to the type of the slave unit, and there is a problem that setting takes time. However, according to the present invention, communication settings can be made without specialized knowledge simply by selecting settings such as “game machine mode” and “PC mode” that have been determined in advance according to the type of child device.

Embodiment 2. FIG.
Next, another embodiment of the present invention for guiding the wireless slave device to the optimum SSID will be described. The configuration of the wireless LAN access point device in the second embodiment (Embodiment 2) is the same as that of the first embodiment shown in FIG. Hereinafter, the operation of the wireless LAN access point device of this embodiment will be described.

  FIG. 5 is a flowchart showing the operation of the second embodiment of the wireless LAN access point device according to the present invention. FIG. 6 is a sequence diagram showing a communication procedure with a wireless slave device in the second embodiment of the wireless LAN access point device according to the present invention. The processing from sequence 41 to sequence 44 is the same as the processing from sequence 31 to sequence 34 shown in FIG. After receiving the Auth Response of sequence 44, the wireless slave device transmits a request (Association Request) for connection to the wireless LAN access point device 22 to the wireless LAN access point device 22 (sequence 45).

  If the wireless LAN access point device 22 has an SSID that is more suitable than the SSID (SSID 23 in the example shown in FIG. 6) to which the wireless slave is trying to connect (YES in step S22), the wireless LAN access point device 22 connects with a StatusCode other than 0. A response to the request (Association Response) is transmitted (sequence 46, step S24). As a result, the wireless slave unit is guided to try to access another access point. In sequence 46, if there is no other suitable SSID (NO in step S22) and the connection is permitted, the wireless LAN access point device 22 returns a status code of Association Response to 0 (step S23). .

  When the Status Code of the Association Response in the sequence 46 is other than 0, the wireless slave device transmits a probe request to another SSID in order to try to connect to another SSID (SSID 24 in the example shown in FIG. 6) (sequence). 47). Note that, as in the first embodiment, the wireless LAN access point device 22 may perform a process of starting unless the SSID that is optimally set is active.

  In sequence 46, even if the wireless LAN access point device 22 transmits a StatusCode other than 0, the wireless slave device may make a connection request (Association Request) to the same SSID again for the convenience of the wireless slave device. is there. In this case, the wireless LAN access point device 22 sets StatusCode to 0 and returns an association response. In other words, the connection is permitted and communication is performed using the SSID for which a connection request is first made.

  According to the wireless LAN access point device 22 of the present embodiment, the wireless slave is guided to connect to the optimum SSID using the Status Code of Association Response. Thereby, the effect similar to 1st Embodiment is acquired.
