  In this embodiment, since the printing service using the DPOF is selected, the status of the service to be executed (service type, name of service to be used, reference destination information of the service execution target object, and service) Is set as status information at the corresponding location of each record constituting the service start request message (M1401) (S803).

In this embodiment, as an example of the status to be implemented,
Service type: Printing, Service name used: DPOF Printing,
Service execution target object: http: // xxxx-yyyy-zz / Print_order
Is set, and Activated (operating) is set in SAS (Service Active Status) defined in “ALTERNATIVE_SERVICE_RECORD” (R1403).

  Further, as setting information of a wireless LAN communication path for implementing the service, the requesting digital camera 101 is directly connected to operate in the wireless LAN AP mode, and the IP address of its own device is set to 192.168.8.0. The fact that xx is desired to be used is stored in “AUXILARY_DATA_REFERENCE” (R1405) in “ALTERNIVE_SERVICE_RECORD” (R1403).

  After completing the setting of the status information, the NFC communication control unit 520 of the digital camera 101 transmits the service start request message (M1401) to the printer 102 (S804, S1003).

  Next, the printer 102 that has received the service start request message (M1401) (S902, S1003) determines whether or not the service designated by the message, that is, the printing service using DPOF in this embodiment can be executed ( S903) is performed.

  If it is determined that the service cannot be executed, a service start response message (M1402) in which a status of failure (notifying that the service cannot be executed) is set is returned to the digital camera 101 (S914, S1004). Then, the printer control processing step of the present invention is completed.

  In this embodiment, since it is determined that it can be executed, it is determined whether the specified service, in this embodiment, the printing service using DPOF has been started on the own device (printer) side (S904). To implement.

  If the service has already been activated, “Activated” is set in the SAS (Service Active Status) defined in “ALTERNATIVE_SERVICE_RECORD” (R1403) in the service start response message (M1402) (S906).

  In the present embodiment, since it has not been started, the printing service using DPOF is started, and at the same time, the SAS (Service Active Status) defined in “ALTERNIVE_SERVICE_RECORD” (R1403) in the service start response message (M1402) is started. ) Is set to Activating (being activated) (S905).

  Next, the printer 102 determines whether or not the wireless LAN communication unit 308 in its own apparatus has already set a wireless LAN communication path (S907).

  In this embodiment, since it has not been set, the wireless LAN setting information specified by the index of “CARRIER_DATA_REFERENCE” (R1504) stored in “AUXILARY_DATA_REFERENCE” (R1405) in “ALTERNATIVE_SERVICE_RECORD” (R1403) The setting information is acquired from the stored reference destination NDEF record, set as a new connection destination of the wireless LAN communication path of the own device (S909), and set as connection destination wireless LAN setting information to be notified to the counterpart device.

  If it has been set, the wireless LAN communication path is set to the new connection destination (S909). If there is the service being executed, communication with the opposite digital camera 101 is performed on the currently set communication path. It is determined whether it is possible (S908).

  As a method for determining whether communication is possible, in this embodiment, the registration status of the ARP table in the own device is confirmed using the MAC address notified from the opposite device as an additional parameter of the wireless LAN setting information. Do. In addition, a service discovery process for an existing wireless LAN communication path using the notified UUID is used.

  As a result of the determination, if it is determined that communication with the opposite device is possible, it is set as the connection destination of the existing wireless LAN communication path (S910). If it is determined that communication is not possible, failure (service is A service start response message (M1402) in which a status of “notifying that execution is not possible” is set is returned to the digital camera 101 (S914, S1004), and then the control processing step of the printer 102 of the present invention is terminated.

  When the setting of the new wireless LAN communication path (S909) is completed and it is confirmed that the communication through the existing wireless LAN communication path is possible (S908, S910), it is determined whether or not the logical address can be assigned to the counterpart device. (S911).

  In the present embodiment, whether or not the logical address can be assigned is determined according to whether or not the DHCP server is operating on the wireless LAN, the wireless LAN communication path setting type (Wi-Fi Direct NFC, Wi-Fi Protected). Whether it is Setup NFC or the like) is used as a criterion.

  When it is determined that the logical address can be assigned, the logical address such as the IP address assigned to “AUXIARY_DATA_REFERENCE” defined in “ALTERNATIVE_SERVICE_RECORD” (R1403) in the service start response message (M1402), the IP address of the own device, etc. Address information is set together with the NDEF payload (S912).

  In this embodiment, since the digital camera side is a wireless LAN AP and the IP address of its own device has already been set, it is determined that the assignment is impossible, and the logical address information for assignment is not set, and the IP address system of the opposite device is used. Set the IP address (192.168.8.0.yy) for the device itself.

  Thereafter, a service start response message (M1402) in which a status of success (notifying that the service can be executed) is set is returned to the digital camera 101 (S913, S1004), and then activated in the corresponding wireless LANSTA mode. After executing (S1005) and service activation (S1006), the control processing step of the printer 102 of the present plan is terminated.

  Next, after receiving the service response message (M1402) (S805, S1003), the digital camera 101 determines whether the service can be performed according to the success / failure status of the service response message (S806).

  When the failure status is received, the control processing process of the proposed digital camera 101 is terminated.

  When the success status is received, it is determined whether or not the wireless LAN communication path connection destination needs to be changed (S807).

  In the present embodiment, since the wireless LAN communication path connection is not performed when the success status is received, the digital camera 101 is activated in the AP mode according to the wireless LAN setting information in the service response message (S1005).

  Next, the presence / absence of notification of logical address information used for wireless LAN connection is confirmed (S809).

  In the present embodiment, since the logical address system designated by the digital camera 101 side and a logical address different from the address assigned to the own apparatus is notified as the printer address, it is determined that the logical address has been notified, The address is set as a destination logical address (S810).

  If there is no notification of the logical address, a service (DHCP client, AUTOIP, etc.) for obtaining the logical address is started by logical addressing control after setting the wireless LAN communication.

  After performing the above processing, the control processing step of the proposed digital camera 101 is terminated.

  In this embodiment, after the digital camera 101 is activated in the AP mode (S1005), the printer 102 is activated in the STA mode (S1005), and the wireless LAN communication path is set (S1006), the trigger on the printer 102 side is used. The “DPOF Printing” service (S1008 to S1010) is executed.

  In the above embodiment, the service start request message transmitted from the digital camera 101 to the printer 102 includes only one wireless LAN communication path setting information. However, the present invention is not limited to this, and a plurality of service start request messages are not limited. Setting information may be included.

  If the printer 102 wants to confirm the setting information of the wireless LAN communication path, the service start request message does not include the setting information of the wireless LAN communication path (NULL information may be set). You can send it.

  In these cases, the setting information of the wireless LAN communication path used for the actual connection is notified by using a service start response message sent back from the printer 102 to the digital camera 101 and is shared between the apparatuses. A logical address can be set.

  As described above, when the proposed control method is used, the setting information for the wireless LAN communication path for executing the service is added to the service start request message, so that the setting information for the handover destination communication path can be shared.

  In addition, since the operation status of the functional block in the device for executing the service corresponding to both the service start request message and the service response message is added and notified, whether the service can be executed, whether there is a waiting time until the start, etc. Can share information.

  Furthermore, even if the information on the operating power mode of the device (power saving mode, battery mode, commercial power mode, etc.) is shared as the operating status of the functional block in the device, the service execution status can be similarly started and started. You can share information such as the presence or absence of waiting time.

  Therefore, when it is confirmed that the “DPOF Printing” service is feasible, a handover to the wireless LAN or Bluetooth (registered trademark) to be used can be performed, and the “DPOF Printing” service can be executed.

(Second embodiment)
With reference to the flowcharts of FIGS. 8 and 9 and the sequence chart of FIG. 11, the “Pictbridge Printing” operation procedure via the wireless LANP2P communication path between the digital camera 101 and the printer 102 in the first embodiment will be described. .
