Description

The present invention relates to a display method , a program, and an information processing apparatus .

  In a wireless LAN (hereinafter referred to as wireless LAN) conforming to the IEEE 802.11 standard series, there are many setting items that must be set before use. Thus, an automatic setting method has been devised for easily setting communication parameters in a wireless device. As an example, a standard for a communication parameter automatic setting method called Wi-Fi Protected Setup (WPS) has been formulated by an organization called Wi-Fi Alliance. Patent Document 1 discloses a device that uses WPS to identify a device type of a terminal device in communication parameter automatic setting protocol processing and provide communication parameters suitable for the terminal device. In addition, WPS communicates between wireless devices and access points and automatically sets the communication parameters. However, one of the wireless devices has an access point function so that devices can communicate wirelessly peer-to-peer. A method has been devised. This method is established by Wi-Fi Alliance as a standard called Wi-Fi Direct. In recent years, a configuration in which an information processing device such as a smartphone or a tablet and an image processing device are connected peer-to-peer using Wi-Fi Direct and the image processing device is used from the information processing device is becoming common.

  Next, communication parameter automatic setting processing by wireless communication in the present embodiment will be described with reference to FIG. FIG. 3 shows a sequence diagram between the information processing apparatus 100 and the image processing apparatus 120. The sequence between the information processing apparatus 100 and the image processing apparatus 120 generally includes an access point search process (F300), a wireless connection establishment process (F303), and a communication parameter automatic setting process (F306). Hereinafter, each sequence will be described. When receiving an instruction to start communication parameter automatic setting processing, the image processing apparatus 120 searches for an access point that can execute the communication parameter automatic setting processing. Specifically, when the user presses a button or the like to enable the wireless communication setting via the operation unit 122 of the image processing apparatus 120, the automatic setting control unit 222 starts searching for an access point by broadcasting. The image processing apparatus 120 transmits a probe request (F301) to search for an access point that can execute the communication parameter automatic setting process.

  The information processing apparatus 100 also enters a state of waiting for access to the access point in its own device when there is an instruction to start communication parameter automatic setting processing through wireless communication by a user operation. When receiving the probe request (F301), the automatic setting control unit 202 of the information processing apparatus 100 analyzes the received probe request. Based on the result of the automatic setting control unit 202, the communication parameter setting unit 203 and the probe response (F302) to which additional information indicating that the communication parameter automatic setting process can be executed are set. The communication parameter providing unit 204 returns a probe response (F302) via the packet transmission unit 207. Here, the probe response returned by the communication parameter providing unit 204 includes the SSID. The automatic setting control unit 222 of the image processing apparatus 120 can recognize that the information processing apparatus 100 can execute the communication parameter automatic setting process by receiving and analyzing the probe response (F302). Note that the automatic setting control unit 202 returns a probe response without adding additional information indicating that the communication parameter automatic setting process can be executed when there is no instruction to start the communication parameter automatic setting process in the information processing apparatus 100. .

  Subsequently, the SSID analysis unit 227 of the image processing apparatus 120 receives and analyzes the SSID included in the probe response (F302) from the automatic setting control unit 222. When the SSID matches a character string stored in a storage device (not shown), the SSID analysis unit 227 performs an association so that the automatic setting control unit 222 performs a temporary wireless connection with the information processing device 100. An association request (F304) is transmitted to do this. The character string will be described later with reference to FIG. When receiving the association request (F304), the automatic setting control unit 202 of the information processing apparatus 100 returns an association response (F305) indicating that the association is possible, and completes the association. Note that, when the association is completed, normal data communication using encryption and authentication cannot be performed because the encryption keys do not match even if the SSIDs match.

  The automatic setting control unit 222 of the image processing apparatus 120 starts communication parameter automatic setting protocol processing with the information processing apparatus 100 by using an EAP (Extensible Authentication Protocol) packet. An EAP packet is a packet that can be communicated between a providing device and a receiving device without encryption or authentication. The communication parameter automatic setting protocol processing is started when the communication parameter setting unit 223 sets an EAP packet and transmits a start message (F307) via the packet transmission unit 228.

  When receiving the communication parameter automatic setting protocol process start message, the automatic setting control unit 202 of the information processing apparatus 100 transmits an EAP Request packet (F308) to the image processing apparatus 120 to start communication parameter negotiation. When receiving the EAP Request packet (F308), the automatic setting control unit 202 transmits an EAP Response packet (F309) to the information processing apparatus 100. By repeating these steps, communication parameter automatic setting is realized without using an access point. That is, the automatic setting control unit 222 functions as a wireless communication unit that performs direct wireless communication with the information processing apparatus without using an access point. The automatic setting control unit 202 functions as a wireless connection unit that performs direct wireless communication with the image processing apparatus without using an access point. Although an example in which the access point is the information processing apparatus 100 will be described, an access point may be provided in the image processing apparatus 120. In that case, the access point search starts from the information processing apparatus 100. Either of the communication parameter automatic setting processes can be applied.

  In the communication parameter automatic setting process (F306), a communication path encryption process for providing communication parameters, an authentication process for determining whether or not communication parameters can be provided, and the like are performed. Various messages for performing these processes are transmitted and received between the image processing apparatus 120 and the information processing apparatus 100. All or a part of each message transmitted from the information processing apparatus 100 includes device information of the information processing apparatus 100. The device information includes a device name (ModelName), an OS version (OS Version), and vendor extension data. The device name of the access point (AbcSmartPhone, etc.) is set as the device name. (AbcOS 1.0 or the like) is set as the OS version. Data defined by the vendor (IPP-PRINT = ON, mDNS = ON, etc.) is set in the vendor extension data. Details of the vendor extension data will be described later in the third embodiment. That is, the image processing apparatus 120 can acquire the device information of the information processing apparatus 100 by performing the communication parameter automatic setting process (F306).

Example 1
A configuration for enabling a predetermined function using the information of the SSID will be described with reference to FIG. The image processing apparatus 120 and the information processing apparatus 100 according to the present embodiment can communicate with each other by wireless communication. A processing flow when the image processing apparatus 120 according to the present exemplary embodiment performs wireless connection using WiFiDirect with the information processing apparatus 100 will be described with reference to FIG. This processing flow is executed by the control unit 121 of the image processing apparatus 120.

  If the image processing apparatus 120 is already wirelessly connected in step S401, the automatic setting control unit 222 backs up the currently connected SSID to the NVRAM 137 of the image processing apparatus 120. In other words, when the image processing apparatus 120 is wirelessly connected to a plurality of users via a wireless LAN or the like, the wireless connection by the wireless LAN must be disconnected in order to communicate with the information processing apparatus 100 by peer-to-peer. Therefore, the automatic setting control unit 222 of the image processing apparatus 120 backs up the SSID, which is an identifier for the wirelessly connected access point, in the NVRAM 137. In S402, the automatic setting control unit 222 performs the access point search process (F300) described in FIG. The automatic setting control unit 222 acquires the SSID as identification information for identifying the information processing apparatus from the information processing apparatus 100 by transmitting a probe request. In S403, the SSID analysis unit 227 compares whether or not the SSID acquired from the automatic setting control unit 222 matches a predetermined character string (such as “AbcSmartPhone_AP”) stored in the storage unit. The predetermined character string is a character string indicating the SSID of a specific information processing apparatus. The specific information processing apparatus is an information processing apparatus that has a function of connecting to an image processing apparatus using a WiFiDirect function and using the image processing apparatus using an IPP-Print function and an mDNS function.

  In S404, the automatic setting control unit 222 ends the process when the SSID analysis unit 227 determines that the character strings do not match. In S404, when the SSID analysis unit 227 determines that the character strings match, the automatic setting control unit 222 backs up the current IPP-Print setting to the NVRAM 137 in S405. In S406, the automatic setting control unit 222 determines whether the IPP-Print function is valid. If the IPP-Print function is valid, printing using IPP can be used, and if the IPP-Print function is invalid, printing using IPP cannot be used. In step S407, the automatic setting control unit 222 enables the IPP-Print function when the IPP-Print function is invalid.

  In step S <b> 408, the automatic setting control unit 222 backs up the current mDNS setting in the NVRAM 137. In step S409, the automatic setting control unit 222 determines whether the mDNS function is valid. If the mDNS function is valid, the search using the mDNS can be used, and if the mDNS function is invalid, the search using the mDNS cannot be used. In S410, when the mDNS function is invalid, the automatic setting control unit 222 enables the mDNS function. That is, the SSID analysis unit 227 functions as an enabling unit, and when it is determined that the character examples match, the automatic setting control unit 222 enables the IPP-Print function and the mDNS function. In addition, the print protocol control unit 232 and the search protocol control unit 231 function as a providing unit, and when the IPP-Print function and the mDNS function are validated, a print service that performs predetermined printing according to a print request from the information processing apparatus. provide.

  In the IPP-Print function and mDNS function validation process, it is assumed that an expiration date is set in advance. Usually, an image processing apparatus having a LAN function is used by a plurality of users via a LAN. Therefore, it is desirable that an expiration date is set for the time when the peer-to-peer connection is made with a specific information processing apparatus. The expiration date may be set to an arbitrary expiration date as long as it is a time during which a print request can be received from a specific information processing apparatus and printing can be executed.

  In the above-described process, the image processing apparatus 120 receives the SSID from the information processing apparatus 100 in the access point search process (F300). The image processing apparatus 120 automatically enables the setting using the received SSID when the setting used for providing the print service such as the IPP-Print function and the mDNS function is invalid when wirelessly connecting. It becomes possible to do.

  Next, referring to FIG. 5, the image processing apparatus 120 according to the present exemplary embodiment disconnects the wireless connection using WiFiDirect from the information processing apparatus 100 and resumes the wireless connection with the access point that was initially connected. The process up to will be described. This processing flow is executed by the control unit 121 of the image processing apparatus 120.

  In step S <b> 501, the automatic setting control unit 222 of the image processing apparatus 120 cancels wireless communication with the information processing apparatus 100. In step S <b> 502, the automatic setting control unit 222 reads a backup of the IPP-Print setting from the NVRAM 137. In step S503, the automatic setting control unit 222 determines whether the read IPP-Print setting is invalid. If the IPP-Print setting is invalid, the automatic setting control unit 222 invalidates the IPP-Print setting in step S504. In step S <b> 505, the automatic setting control unit 222 reads the mDNS setting backup from the NVRAM 137. In step S506, the automatic setting control unit 222 determines whether the read mDNS setting is invalid. If the mDNS setting is invalid, the automatic setting control unit 222 invalidates the mDNS setting in step S507. In step S <b> 508, the automatic setting control unit 222 reads the SSID backup from the NVRAM 137. If a backup of the SSID exists, in S509, the automatic setting control unit 222 connects to the backed-up SSID. In S510, the automatic setting control unit 222 deletes the SSID backup.

  In the above-described processing, the IPP-Print setting and the mDNS setting have been described as examples. However, the setting to be validated is not limited to these. A person skilled in the art can assume that any setting is valid as long as the setting can be provided by the image processing apparatus via wireless communication. As a matter of course, the present invention is not limited to the step of setting mDNS after the IPP-Print setting is enabled, and various settings may be enabled in an arbitrary step.

  As described above, it is assumed that an image processing apparatus having a LAN function is used by a plurality of users via a LAN. In such an environment, the image processing apparatus is operated by connecting to a specific access point that mediates access to the LAN in order to connect to the LAN. In such an environment, as described with reference to FIG. 4, if a wireless connection using WiFiDirect is performed with the information processing apparatus 100, the connected access point changes, and the LAN cannot be connected. Therefore, when the image processing apparatus 120 interrupts the wireless connection using WiFiDirect with the information processing apparatus 100 as described with reference to FIG. 5, it promptly returns to the original access point connected to connect to the LAN. Reconnect. As a result, a user who originally used the image processing apparatus via the LAN can continue to use the image processing apparatus via the LAN.

  The process of temporarily enabling the IPP-Print function and the mDNS function has been described with reference to FIGS. 4 and 5 in order to improve convenience. By the way, in WiFiDirect, connection is performed peer-to-peer. Therefore, a configuration is also conceivable in which unnecessary security processing is omitted and the processing capability of the image processing apparatus is improved by disabling the security function of the image processing apparatus during WiFiDirect connection. As the security function, an IPsec function, an IP filter function, an SSL function, or the like can be considered.

  The effect of the first embodiment is that when the SSID of the access point to which the image processing apparatus 120 is connected matches a predetermined value, the image processing apparatus 120 increases the convenience by enabling a predetermined function. is there.

(Example 2)
In the first embodiment, in the access point search process (F300), a predetermined function used by the image processing apparatus in the print service is validated using the SSID. In the second embodiment, a configuration for enabling a predetermined function using existing data of a WPS message will be described with reference to FIGS. 6 and 7. The EAP message transmitted from the communication parameter automatic setting function unit 201 of the information processing apparatus 100 in the communication parameter automatic setting process (F306) in FIG. 3 includes a plurality of attributes (601 in FIG. 6). Hereinafter, specific data stored in each attribute will be described. In Message Type, data representing the message type is stored. Serial Number stores the serial number of the wireless device. In Model Name, the device name of the wireless device is stored. The OS version stores the OS version of the wireless device. In addition, various attribute data necessary for communication parameter negotiation are also stored.

  A processing flow when the image processing apparatus 120 according to the present exemplary embodiment performs wireless connection using WiFiDirect with the information processing apparatus 100 will be described with reference to FIG. This processing flow is executed by the control unit 121 of the image processing apparatus 120.

  In step S <b> 701, when the image processing apparatus 120 is already wirelessly connected, the automatic setting control unit 222 of the image processing apparatus 120 backs up the currently connected SSID to the NVRAM 137. In step S702, the communication parameter automatic setting process described with reference to FIG. 3 is performed. Specifically, the automatic setting control unit 222 acquires the WPS message set by the communication parameter setting unit 203 of the information processing apparatus 100 in the communication parameter automatic setting process (F306) of FIG. The WPS message includes ModelName and OSVersion of the information processing apparatus 100.

  In step S <b> 703, the communication parameter analysis unit 226 compares whether the ModelName and OSVersion acquired from the automatic setting control unit 222 match a predetermined character string stored in the storage unit. The predetermined character string is a character string indicating a specific information processing apparatus, and in this embodiment, AbcSmartPhone, AbcOS1.0 ”or the like is used. The specific information processing apparatus is an information processing apparatus that has a function of connecting to an image processing apparatus using a WiFiDirect function and using the image processing apparatus using an IPP-Print function and an mDNS function.

  If the communication parameter analysis unit 226 determines that the character strings do not match in S704, the automatic setting control unit 222 ends the process. If the communication parameter analysis unit 226 determines that the character strings match in S704, the automatic setting control unit 222 backs up the current IPP-Print setting to the NVRAM 137 of the image processing apparatus 120 in S705. In step S706, the automatic setting control unit 222 determines whether the IPP-Print function is valid. If the IPP-Print function is invalid, the automatic setting control unit 222 validates the IPP-Print function in step S707. In step S <b> 708, the automatic setting control unit 222 backs up the current mDNS setting to the NVRAM 137 of the image processing apparatus 120. In step S709, the automatic setting control unit 222 determines whether the mDNS function is valid. If the mDNS function is invalid, the automatic setting control unit 222 validates the mDNS function in step S710. Note that the processing flow executed when the image processing apparatus 120 of this embodiment disconnects the wireless connection using WiFiDirect with the information processing apparatus 100 is the same as the processing flow described in FIG.
