Description

  The present invention relates to a communication device, a control method of the communication device, and a program.

  The Wi-Fi Alliance has established a standard called Wi-Fi Direct (registered trademark). In Wi-Fi Direct, a protocol for determining whether a communication device such as a printing device or a PC operates as an access point or a client is defined. By executing this protocol, it is possible to automatically determine the communication device to be an access point and the communication device to be a client. By using this Wi-Fi Direct, there is no need to separately prepare an access point, and communication devices can directly execute wireless communication.

  FIG. 1 is a diagram for briefly explaining the processing sequence of Wi-Fi Direct. The printing apparatus and the portable terminal are each an example of an information processing apparatus supporting Wi-Fi Direct.

  First, the printing apparatus and the portable terminal each search for a device to specify a communication partner (step S101). When the communication partner is specified by device search, it is determined which becomes an access point (Group Owner) and which becomes a client (Client) (step S102). The process of step S102 is called role determination. In FIG. 1, as a result of role determination in step S102, it is assumed that the printing apparatus has become GroupOwner and the portable terminal has become Client.

  Next, by using the WPS (Wi-Fi Protected Setup) established by the Wi-Fi Alliance, by providing parameters for connecting from the printing apparatus as the GroupOwner to the portable terminal as the Client, the printing apparatus and The parameters are shared with the portable terminal (step S103). Then, secure connection is performed using the parameters (step S104). In addition, until the process of step S104 is completed, the communication of the data link layer of the OSI reference model is executed.

  When the secure connection is completed, addressing for performing IP communication between the printing apparatus and the portable terminal is performed (step S105). At this time, the printing apparatus as the GroupOwner operates as a DHCP server, and assigns an IP address to the mobile terminal as the Client. In the processes after step S105, communication in a layer higher than the network layer of the OSI reference model becomes possible.

  By performing the above processing, wireless communication is established between the printing apparatus and the portable terminal. By using this wireless communication, the printing apparatus and the portable terminal can directly communicate with each other without preparing a separate access point. Patent Document 1 describes transmitting and receiving voice data and photo data using the Wi-Fi Direct.

  The communication device can easily establish wireless communication with an external device by Wi-Fi Direct. The communication apparatus can use various services (for example, printing and storage) provided by the external apparatus using the wireless communication established by Wi-Fi Direct.

  However, depending on the environment using Wi-Fi Direct, it may not be desirable to provide a specific service. For example, in the case of a printing apparatus, it may be desirable to prohibit the use of a print service using Wi-Fi Direct in order to restrict the use of the print function only when a print job is input from a PC using a wired LAN. Although patent document 1 describes transmitting / receiving audio | speech data and photography data using Wi-FiDirect, prohibiting utilization of these functions is not considered at all.

  Therefore, an object of the present invention is to provide a communication apparatus capable of setting a service to be provided to an external apparatus among a plurality of services.

  In order to solve the problems described above, the communication device provided by the present invention is a communication device that has a Wi-Fi Direct function and provides a service to an external device wirelessly connected by the Wi-Fi Direct function. Setting means for setting a service to be provided to an external device and a service not to be provided to an external device among a plurality of services possessed by the communication device; and display means for displaying a connection screen regarding the Wi-Fi Direct function. The connection screen includes an instruction object instructing a user to execute the connection process for establishing a wireless connection by the Wi-Fi Direct function, and the connection screen further includes: The service provided by the communication device to the external device is based on the result of the setting by the setting means. There characterized in that it is displayed in a discriminable state.

  According to the present invention, it is possible to set a service to be provided to an external device among a plurality of services.

  The storage service 307 provides storage services to external devices. Specifically, an electronic file such as image data received from an external device is stored in a memory such as the HDD 205 or the like.

  In the present embodiment, the print service 306 and the storage service 307 have been described as the service provided by the service unit 305 as an example, but other services may be provided.

  FIG. 4 is a diagram showing a hardware configuration of the portable terminal 400. As shown in FIG. The portable terminal 400 is also an example of a communication device capable of executing wireless communication, similarly to the printing device 200. The mobile terminal 400 is, for example, a device such as a smartphone, a mobile phone, a tablet, or a digital camera.

  The CPU 401 reads out the control program stored in the ROM 403 and controls the overall operation of the portable terminal 400. A RAM 402 is used as a main memory of the CPU 401 and a temporary area such as a work area. The flash memory 404 is a non-volatile memory for storing data, various programs, or various information tables.

  The operation unit 405 includes a liquid crystal display unit having a touch panel function and hard keys. The user can check the screen displayed on the operation unit 405, and can input various instructions to the printing apparatus 200 using the touch panel.

  The wireless LAN I / F 406 performs wireless communication with an external apparatus such as the printing apparatus 200. The wireless LAN I / F 406 can transmit, for example, image data stored in a memory such as the flash memory 404 to the printing apparatus 200 as print data.

  In the portable terminal 400, one CPU 401 executes each process shown in the flowchart to be described later using one memory (RAM 402), but other modes may be used. For example, a plurality of CPUs and a plurality of memories can be cooperated to execute each process shown in the flowchart to be described later.

  Next, the flow of processing of the entire communication system of this embodiment will be described using the sequence diagram of FIG. The communication system of the present embodiment is configured of a portable terminal 400 and a printing apparatus 200. The printing apparatus 200 includes a print service 306 and a storage service 307.

  First, in step S501, the portable terminal 400 and the printing apparatus 200 execute connection processing based on Wi-Fi Direct. The connection process executed in step S501 is the same process as the process described in FIG. 1, and this connection process allows the portable terminal 400 and the printing apparatus 200 to directly execute wireless communication.

  Next, in step S502, the portable terminal 400 inquires the printing apparatus 200 about available services (services provided by the printing apparatus 200). Then, the printing apparatus 200 that has received this inquiry responds to the portable terminal 400 with available services (services provided by the printing apparatus 200) in step S503.

  In the present embodiment, not all services provided in the printing apparatus 200, that is, the print service 306 and the storage service 307 are not responded in step S503. In the present embodiment, the printing apparatus 200 is set in advance by the user for the service provided to the external apparatus and the service not provided. Then, the service set to be provided is responded in step S503, and the service set not to be provided is not responded in step S503.

  The setting screen 600 in FIG. 6 is a setting screen for the user to set whether to provide the service to the external device for each of the services provided by the printing apparatus 200, and is displayed on the operation panel 211 of the printing apparatus 200. Be done. The settings on the setting screen 600 are applied when using a service using Wi-Fi Direct. In the setting screen 600, the print service is set to be provided to the external apparatus (permission of use of the service), and the storage service is set not to handle the external apparatus at least (do not permit use of the service). This setting can be changed by the user using the icon 601 and the icon 602, respectively. When the user presses the icon 603 after setting the desired setting, the content set on the setting screen 600 is stored in the memory such as the HDD 205 by the storage unit 302.

  In the present embodiment, the setting screen 600 can be set by any user. However, by introducing the user authentication function to the printing apparatus 200, only a specific user (for example, a user having administrator authority) can set the setting screen 600. You may be able to set

  In step S504, the portable terminal 400 that has received the response in step S503 displays a list of available services. The service selection screen 700 of FIG. 7A is an example of the screen displayed in step S 504, and is displayed on the operation unit 405 of the portable terminal 400.

  The service selection screen 700 of FIG. 7A is displayed when a response indicating that the print service and the storage service are available is received in step S503. In the service selection screen 700, the user can select a desired service of the print service and the storage service using the icon 701 and the icon 702.

  On the other hand, when the response received in step S 503 is only the print service, the service selection screen 710 of FIG. 7B is displayed on the operation unit 405 of the portable terminal 400. Unlike the service selection screen 700, the storage service is not displayed on the service selection screen 710.

  When the user selects a desired service on the screen selected in step S504, the service selected by the user is used in step S505. When the user selects the print service, the portable terminal 400 transmits print data to the printing apparatus 200 in step S505, and the printer 207 of the printing apparatus 200 executes printing based on the print data. When the user selects the storage service, the electronic file selected by the user is transmitted from the portable terminal 400 to the printing apparatus 200 in step S505, and the printing apparatus 200 receives the electronic file received in a predetermined storage area such as the HDD 205. accumulate.

  As described above, the printing apparatus 200 can set the service provided to the external apparatus and the service not provided for the plurality of services provided by the printing apparatus 200 using the setting screen 600. Then, in the external device (for example, the portable terminal 400), only the service set to be provided to the external device can be used at the time of Wi-Fi Direct connection.

  Although it has been described in step S503 that only available services are returned, unavailable services may also be returned. Specifically, the print service may be available, and the storage service may not be available, in step S503. In this case, since the portable terminal 400 can grasp the existence of the storage service, the service selection screen 720 of FIG. 7C is displayed in step S504. On the service selection screen 720, the storage service notified that it can not be used is displayed as an icon 721 in an invalid state (for example, grayed out) in which the user's selection is not accepted.

  Next, processing performed by the printing apparatus 200 when connecting Wi-Fi Direct will be described using the flowchart in FIG. 8. Each step shown in the flowchart of FIG. 8 is processed by the CPU 202 loading a program stored in a memory such as the ROM 204 into the RAM 203 and executing the program. In the printing apparatus 200, it is assumed in the setting screen 600 in FIG. 6 that the user has set in advance whether or not to provide each of the services provided in the printing apparatus 200 to the external apparatus.

  First, in step S801, the operation panel 211 displays a reception screen. The reception screen displayed in step S801 is a screen for receiving, from the user, an execution instruction for executing a connection process based on Wi-Fi Direct. An example of the acceptance screen displayed in step S801 will be described with reference to FIG.

  The reception screen 900 of FIG. 9A is an example of the reception screen displayed in step S801. The reception screen 900 is a screen displayed when the setting screen 600 is set in advance to “provide” a print service to an external apparatus and “storage service is not provided to an external apparatus”. By the user selecting the icon 901, connection processing based on Wi-Fi Direct is performed. Although both the available service and the unavailable service are displayed on the reception screen 900, only the available service may be displayed and the unavailable service may not be displayed.

  Further, in the area 902 of the reception screen 900, it is displayed that the print service can be used and the storage service can not be used according to the setting of the setting screen 600. In the present embodiment, the user of the portable terminal 400 executes connection processing by instructing the execution of connection processing in both the printing apparatus 200 and the portable terminal 400, and wireless communication between the printing apparatus 200 and the portable terminal 400. To establish That is, the user may view the reception screen 900 without knowing the settings made on the setting screen 600, and even such a user checks whether the desired service can be used by checking the area 902. be able to. If the content of the area 902 is not displayed, after performing connection processing based on Wi-Fi Direct to establish wireless communication, the timing at which the service (service set as unavailable) is actually tried is used. You will know that you can not use the service. By displaying the area 902, the user can confirm whether or not the desired service is available before the connection process is performed, thus preventing unnecessary connection process execution. it can.

  Also, as a matter of course, the display content of the area 902 changes in accordance with the setting content of the setting screen 600. If the setting screen 600 is set to provide both the print service and the storage service to the external apparatus, the area 902 displays that both the print service and the storage service can be used.

  Further, when all of the plurality of services provided in the printing apparatus 200 are set as a service not provided to the external apparatus by the setting screen 600, even if connection processing based on Wi-Fi Direct is executed to establish wireless communication, The external device (for example, the portable terminal 400) can not use any service. That is, even if connection processing is executed, it is useless, so when all of the plurality of services provided in the printing apparatus 200 are set as services not provided to the external apparatus, the operation panel 211 displays the reception screen shown in FIG. Display 910. In the reception screen 910, the printing apparatus 200 is controlled so as not to execute the connection process by displaying the icon 911 in an invalid state (displayed in gray, for example) where the operation from the user is not received. This can prevent the user from instructing the execution of useless connection processing.

  It returns to description of the flowchart of FIG. When the operation panel 211 displays the reception screen in step S801, the CPU 202 determines in step S802 whether or not to execute connection processing. When an instruction to execute the connection process is received from the user (the user selects the icon 901), the CPU 202 determines in step S802 that the connection process is to be performed, and the process advances to step S803. On the other hand, when the execution instruction of the connection process has not been received from the user, the process waits until it receives it.

  Next, in step S803, the wireless LAN I / F 212 executes connection processing based on Wi-Fi Direct. The details of the connection process will be described later with reference to FIG. By the connection process of step S803, wireless communication is established between the printing apparatus 200 and the external apparatus (for example, the portable terminal 400). The following description will be given assuming that wireless communication has been established with the portable terminal 400.

  Next, in step S804, the CPU 202 determines whether an inquiry for available services has been received from the portable terminal 400. This inquiry is transmitted by the portable terminal 400 in step S1103 of FIG. 11 described later. If the CPU 202 determines that an inquiry for available services has been received from the portable terminal 400, the process advances to step S805. On the other hand, when the CPU 202 determines that the available service inquiry has not been received from the portable terminal 400, the process waits until it is received.

  Next, in step S805, the wireless LAN I / F 212 responds to the received inquiry with available services (corresponding to step S503 in FIG. 5). This response is made based on the settings on the setting screen 600 of FIG. In the present embodiment, the service set in the setting screen 600 to be provided to the external device is responded as a usable service in step S805, and the service set in the setting screen 600 not to be provided to the external device is not replied in step S805. .

  Next, the connection processing described in step S 803 of FIG. 8 will be described using the flowchart of FIG. Each step shown in the flowchart of FIG. 10 is processed by the CPU 202 loading a program stored in a memory such as the ROM 204 into the RAM 203 and executing the program.

  First, in step S1001, the wireless LAN I / F 212 executes device search. Device search is processing for specifying a connection destination. In the present embodiment, the external device also executes the device search according to the user's operation. In the device search of step S1001, the external device which is executing this device search is specified as the connection destination. In the following description, it is assumed that the portable terminal 400 is identified as the connection destination.

  Next, in step S1002, the wireless LAN I / F 212 determines which of the portable terminal 400 and the printing apparatus 200 becomes an access point (Group Owner) and which becomes a client (Client). This process is called role determination.

  Next, in step S1003, the wireless LAN I / F 212 shares parameters with the printing apparatus 200 using WPS. By the process of step S1003, parameters are shared between the portable terminal 400 and the printing apparatus 200.

  Next, in step S1004, the wireless LAN I / F 212 executes secure connection using the parameters shared in step S1003. Note that the process is executed as communication of the data link layer of the OSI reference model until the process of step S1004 is completed.

  Next, in step S1005, the wireless LAN I / F 212 performs IP connection with the printing apparatus 200. In step S1005, addressing for performing IP communication between the portable terminal 400 and the printing apparatus 200 is performed. At this time, an IP address is assigned to the device of which the device of GroupOwner is a Client. By executing these processes described with reference to FIG. 10, wireless communication is established between the portable terminal 400 and the printing apparatus 200. In step S1005 and subsequent steps (steps S804 and S805 in FIG. 8), communication in the upper layer than the network layer of the OSI reference model becomes possible.

  Next, processing performed by the portable terminal 400 when connecting Wi-Fi Direct will be described with reference to the flowchart in FIG. Each step shown in the flowchart of FIG. 11 is processed by the CPU 401 loading a program stored in a memory such as the ROM 403 into the RAM 402 and executing the program.

  When an instruction to execute connection processing is received from the user, in step S1101, the wireless LAN I / F 406 executes connection processing based on Wi-Fi Direct. This connection process is the same process as the connection process performed in the printing apparatus 200 described with reference to FIG. 10, and thus detailed description will be omitted. In the present embodiment, wireless communication is established between the portable terminal 400 and the printing apparatus 200 by the connection process of step S1101.

  When the connection process in step S1101 is completed, in step S1102, the wireless LAN I / F 406 inquires available services to the printing apparatus 200 (corresponding to step S502 in FIG. 5). In the present embodiment, the inquiry executed in step S1102 is a process executed in response to the establishment of wireless communication by the connection process of step S1101 and is automatically executed without the need for a user's instruction. . Note that the process of step S1102 is not limited to this, and may be executed after confirming whether or not to inquire the user about a service.

  Next, in step S 1103, the CPU 401 determines whether a response to the available service inquiry has been received from the printing apparatus 200. If the CPU 401 determines that a response has been received, the process advances to step S1104. On the other hand, when the CPU 401 determines that the response has not been received, the CPU waits until the response is received.

  Next, in step S1104, the operation unit 405 of the portable terminal 400 displays available services based on the received response. When a response indicating that the print service and the storage service are available is received from the printing apparatus 200, the operation unit 405 displays the service selection screen 700 of FIG. 7A. On the other hand, when the received response is only the print service, the operation unit 405 displays the service selection screen 710 of FIG. 7B. Unlike the service selection screen 700, the storage service is not displayed on the service selection screen 710. As described above, the operation unit 405 displays based on the response received from the printing apparatus 200 so that the user can distinguish between the available service and the unavailable service of the portable terminal 400.

  The user can select and use a desired service from the services displayed in step S1104. When the user instructs to use a desired service on the service selection screen 700 or the like, a request for using the service is transmitted to the printing apparatus 200, and the printing apparatus 200 executes the instructed service.

  As described above, according to the present embodiment, services provided by the printing apparatus 200 to the external apparatus at the time of Wi-Fi Direct connection (services that the external apparatus can use) and services not provided to the external apparatus (Services that can not be used by external devices) can be set.

  Also, the printing apparatus 200 displays, on the reception screen for receiving from the user an instruction to execute the connection process based on Wi-Fi Direct, so that the user can distinguish between services that can be used for services provided by the printing apparatus 200 and services that can not be used. . As a result, the user can grasp whether or not the desired service can be used at a timing prior to the actual execution of the connection process, and therefore, the setting is made to useless the connection process when the desired service can not be used. Can be prevented.
