Description

The present invention relates to an information processing device, a terminal device, a control method and a program.

Recently, the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard has defined 802.11a/b/g/n, as well as the higher speed 802.11ac. 802.11ac/a uses the 5 GHz frequency band. 802.11b/g, on the other hand, uses the 2.4 GHz frequency band. Also, 802.11n supports both 2.4 GHz and 5 GHz, although the 2.4 GHz frequency band is commonly used. Common mobile terminals and printing devices support all of these wireless LAN standards.
Further, as means for directly connecting a mobile terminal and a printing apparatus via a wireless LAN, a connection method using handover is widely used (Patent Document 1). The mobile terminal issues an instruction to start the wireless direct mode of the printing apparatus by NFC (Near Field Radio Communication) or BLE (Bluetooth (registered trademark) Low Energy). After activating the wireless direct mode, the printing device transmits its own SSID and key information to the mobile terminal using NFC or BLE. The mobile terminal uses the received SSID and key information to establish a wireless LAN connection to the printing device.

JP 2013-062786 A

If the operating frequencies of the mobile terminal and the printing device do not match, the printing device cannot establish a connection with the mobile terminal. For example, if the mobile terminal operates at 802.11n at 2.4 GHz and the printer activates the wireless direct mode at 802.11ac at 5 GHz, the operating frequencies do not match, so a wireless LAN connection cannot be established. .
Therefore, even if the user uses the mobile terminal to perform NFC touch or BLE proximity communication, a wireless LAN connection cannot be established between the printing apparatus and the mobile terminal if the frequencies do not match.

The present invention is an information processing device that operates as an access point for performing wireless communication with a terminal device without going through an external access point and performs wireless communication with the terminal device connected to the access point, receiving means for receiving information of wireless communication of the terminal device by wireless communication using a communication method different from that of wireless communication via which the information processing device receives wireless communication information; determining means for determining whether an operating frequency band to be used when operating the terminal device as the access point is included in the operating frequency band of the terminal device; If it is determined that the operating frequency band to be used is included in the operating frequency band of the terminal device, the connection information for connecting to the access point is sent to a wireless communication method different from that of wireless communication via the access point. While controlling transmission to the terminal device by communication, when it is determined by the determination means that the operating frequency band to be used when operating as the access point is not included in the operating frequency band of the terminal device, and transmitting means for controlling to transmit information not including the connection information to the terminal device by the different wireless communication.

ADVANTAGE OF THE INVENTION According to this invention, the connection error of wireless communication by the mismatch of the information of wireless communication can be avoided.

FIG. 4 is a diagram showing a UI example for changing the frequency band in the wireless direct mode in the printing apparatus 210. As shown in FIG. There are exclusive settings of "Auto", "5 GHz" and "2.4 GHz". For example, if the user wants to use only 802.11ac, select "5 GHz". The printing device 210 then starts the wireless direct mode with 802.11ac. Also, if the user wants to use only 802.11n, select "2.4 GHz". The printing device 210 then initiates the wireless direct mode with 802.11n. "Automatic" means that all wireless LAN standards supported by the printing device 210 are enabled and the setting starts with the operating frequency instructed by the other party. Also, the printing apparatus 210 starts with the faster 802.11ac if there is no instruction from the opposite side, but this can be changed by setting and may start with 802.11n.
FIG. 4 is also an example of a UI for changing the frequency band in the mobile terminal 200. FIG. For example, if the user wants to use only 802.11ac, select "5 GHz". The mobile terminal 200 then has only 802.11ac enabled and only searches for SSIDs in the 5 GHz band. Also, if the user wants to use only 802.11n, select "2.4 GHz". Then, the mobile terminal 200 has only 802.11n enabled and only searches for SSIDs in the 2.4 GHz band. "Automatic" enables all wireless LAN standards that the mobile terminal 200 supports. For example, if mobile terminal 200 supports 802.11ac and 802.11n, mobile terminal 200 searches for SSIDs on both 5 GHz and 2.4 GHz.
FIG. 5 is a diagram showing an example of a UI for starting and stopping the wireless direct mode of the printing device 210. As shown in FIG. When the user selects the "start" button on this screen, the printing device 210 starts wireless direct. Further, when the user selects the "stop" button after starting the wireless direct, the printing apparatus 210 stops the wireless direct.

Next, processing for the printing apparatus 210 to acquire the frequency band information of the opposite terminal using NFC and start the wireless direct mode with the matching operating frequency will be described using the flowchart of FIG. 6 .
The flowchart shown in FIG. 6 is the flowchart of the printing apparatus 210 .
In S<b>501 , the CPU 301 determines whether NDEF data has been written from the mobile terminal 200 via the NFC chip 413 . An example of NDEF data to be written is shown in FIG. The NDEF data stores instruction information as shown in FIG. 8, frequency information and frequency standard information on which the mobile terminal 200 operates. The instruction information includes, for example, "wireless direct start instruction" and "wireless direct stop instruction". In this embodiment, the instruction information stores "wireless direct start instruction". If the CPU 301 determines that the NDEF data has been written, the process proceeds to S502, and if it determines that the NDEF data has not been written, the process of S501 is repeated. The wireless direct start instruction is an example of a wireless connection start request.
In step S<b>502 , the CPU 301 determines whether the wireless direct mode has already started in the printing apparatus 210 . If the wireless direct mode has already started, the CPU 301 proceeds to S505, and if the wireless direct mode has not started yet, the CPU 301 proceeds to S503.
In S505, the CPU 301 only needs to notify the currently operating SSID and key information, so the SSID and key information are stored in the response NDEF data as shown in FIG. Further, the CPU 301 stores a record of "already started" in the "instruction result" area in FIG. CPU 301 notifies mobile terminal 200 of these NDEF data via NFC chip 413 .

In S503, the CPU 301 determines whether frequency information of the mobile terminal 200 is stored in the written NDEF data. If the frequency information is not stored, the CPU 301 proceeds to S508, and if the frequency information is stored, the CPU 301 proceeds to S504.
In S508, the CPU 301 determines the operating frequency setting of its own device. For example, the CPU 301 may make a determination based on preset frequency settings as shown in FIG. The CPU 301 proceeds to S509 if the operating frequency is set to "2.4 GHz", and proceeds to S510 if the operating frequency is set to "5 GHz" or "automatic".
In S509, the CPU 301 starts the wireless direct mode according to the 802.11n standard.
On the other hand, if the operating frequency is set to "5 GHz" in S510, the CPU 301 starts the wireless direct mode according to the 802.11ac standard. Also, when the operating frequency is set to "auto", the CPU 301 starts the wireless direct mode with the higher speed 802.11ac standard. However, in the case of the "automatic" setting, in which frequency band the wireless direct mode is started may be changed by setting.
When the start of Wireless Direct is completed, in S505, the CPU 301 stores the SSID, key information, "successful start instruction", started frequency information, etc. in the NDEF data of FIG.

Also, when frequency information of the mobile terminal 200 is stored in the NDEF data, the CPU 301 performs frequency matching determination processing in S504. The frequency match determination process will be explained using the flowchart of FIG.
In S601, the CPU 301 determines the frequency value. Alternatively, a wireless LAN standard name by which frequency information can be specified may be used instead of the frequency value. If the CPU 301 determines that the frequency is 5 GHz, it proceeds to S606; if it determines that the frequency is 2.4 GHz, it proceeds to S610; if it determines that the frequency is Auto, it proceeds to S602.
In S606, the CPU 301 compares it with the frequency setting of its own device to determine whether they match. The CPU 301 advances to S608 if the self-device is set to 2.4 GHz, and advances to S607 if the self-device is set to 5 GHz or is automatically set.
In step S<b>608 , the CPU 301 determines not to start the wireless direct mode because it cannot be connected due to frequency mismatch even if it is started anyway.
In S609, the CPU 301 determines that the frequency match determination has failed.
In S607, the CPU 301 starts the wireless direct mode at 5 GHz of the 802.11ac standard. Then, in S605, the CPU 301 determines that the frequency match determination has succeeded. S607 is an example of control for starting wireless connection.

Also, in S610, the CPU 301 compares it with the frequency setting of its own device to determine whether or not they match. The CPU 301 advances to S612 if the self-device is set to 5 GHz, and advances to S611 if the self-device is set to 2.4 GHz or is automatically set.
In step S<b>612 , the CPU 301 determines not to start the wireless direct mode because it cannot be connected due to frequency mismatch even if it is started anyway.
In S613, the CPU 301 determines that the frequency match determination has failed.
In S611, the CPU 201 starts the wireless direct mode at 2.4 GHz of the 802.11n standard. Then, in S605, the CPU 301 determines that the frequency match determination has succeeded. S611 is an example of control for starting wireless connection.

In S602, the CPU 301 determines the frequency setting of its own device. The CPU 301 advances to S603 if the setting of the own device is 2.4 GHz, and advances to S604 if the setting of the own device is 5 GHz. Also, when the self-device is automatically set, the CPU 301 can start the connection at any frequency, but starts the wireless direct mode at 5 GHz, which is the higher speed of the 802.11ac standard.
In S603, the CPU 301 starts the wireless direct mode at 2.4 GHz of the 802.11n standard. S603 is an example of control for starting wireless connection.
In S604, the CPU 301 starts the wireless direct mode at 5 GHz of the 802.11ac standard. S604 is an example of control for starting wireless connection.
Then, in S605, the CPU 301 determines that the frequency match determination has succeeded.

Returning to the description of FIG.
If the result of the frequency matching determination process is successful, in S505 the CPU 301 stores the SSID, key information, the instruction result "success", the started frequency information, etc. in the NDEF data of FIG.
On the other hand, if the result of the frequency match determination process is failure, in S506 the CPU 301 displays an error screen on the operation unit 309 to the effect that connection is not possible due to frequency mismatch, as shown in FIG.
Then, in S<b>507 , the CPU 301 stores the instruction result “failure due to frequency mismatch” in the NDEF data and notifies the mobile terminal 200 of it.

Also, FIG. 12 is a flow chart of the mobile terminal 200 .
In S<b>1001 , the CPU 401 stores “wireless direct start instruction” data in the command instruction area of the NDEF data.
Next, in S1002, the CPU 401 determines whether or not to include the frequency information of its own device in the NDEF data. If the CPU 401 determines to include the frequency information of its own device, the process proceeds to S1003, and if the frequency information of the own device cannot be obtained for some reason, the CPU 401 creates NDEF data without storing the frequency information, and proceeds to S1012.
In S1003, the CPU 401 determines the operating frequency setting of its own device. The CPU 401 proceeds to S1004 if the operating frequency setting is 2.4 GHz, to S1006 if the operating frequency setting is 5 GHz, and to S1005 if the operating frequency setting is automatic.
In S1004, the CPU 401 stores 2.4 GHz data in the frequency information area of the NDEF data. Also, the CPU 401 stores 802.11n data corresponding to, for example, 2.4 GHz in the wireless LAN standard information area.
In S1006, the CPU 401 stores 5 GHz data in the frequency information area of the NDEF data. Also, the CPU 401 stores data of 802.11ac corresponding to 5 GHz, for example, in the wireless LAN standard information area.
In S1005, the CPU 401 stores automatic data in the frequency information area of the NDEF data. Further, the CPU 401 stores, for example, data of 802.11n and 802.11ac of all supported wireless LAN standards in the wireless LAN standard information area.
After the creation of the NDEF data is completed, the CPU 401 transmits the NDEF data to the printing device 210 via the NFC chip 413 in S1007. After that, the CPU 401 waits for an NFC data response from the printing device 210 .

In S1008, upon receiving the NFC data response from the printing device 210 via the NFC chip 413, the CPU 401 analyzes the received NDEF data. The CPU 401 acquires the "instruction result" area of the received NDEF data, and if the data "start instruction failure due to operating frequency mismatch" is stored, the process advances to step S1011, and the data "other start instruction error" is stored. If so, the process proceeds to S1015. Further, the CPU 401 acquires the "instruction result" area of the received NDEF data, and when the data "start instruction successful" is stored, the process proceeds to S1009.
In S1011, the CPU 401 displays a frequency mismatch error screen as shown in FIG.
Also, in S1015, the CPU 401 displays a connection error screen as shown in FIG. The “other start instruction error” may be, for example, the case where the wireless direct setting is invalid on the printing apparatus 210 side.
In step S<b>1009 , the CPU 401 transmits a wireless LAN connection request to the printing apparatus 210 using the SSID and key information stored in the received NDEF data. A wireless LAN connection request is an example of a wireless connection request.
Then, in S1010, the CPU 401 determines whether the connection has succeeded. If the CPU 401 determines that the connection has succeeded, it ends the processing of the flowchart shown in FIG. 12, and if it determines that the connection has failed, it proceeds to S1015. For example, even if the frequency information matches, the CPU 401 determines that the connection has failed if the connection fails because the maximum number of wireless direct connections has already reached the upper limit on the printing apparatus 210 side. In S1015, the CPU 401 displays a connection error screen as shown in FIG. In addition, even if frequency information is not stored in the received NDEF data, but the "instruction result" of the NDEF data is "start instruction successful", the CPU 401 attempts connection in S1009, but there is a possibility that the operating frequencies do not match. There is In this case as well, it is determined in S1010 that the connection has failed, and in S1015 the CPU 401 displays a connection error screen as shown in FIG.

In S<b>1012 , the CPU 401 transmits NDEF data with empty frequency information to the printing apparatus 210 .
In S1013, the CPU 401 receives the NDEF response data from the printing device 210 and attempts to connect to the printing device 210 using the acquired SSID and key information.
In S1014, the CPU 401 determines whether the connection has succeeded. If the CPU 401 determines that the connection has succeeded, it ends the processing of the flowchart shown in FIG. 12, and if it determines that the connection has failed, it proceeds to S1015. In S1015, the CPU 401 displays a connection error screen as shown in FIG. Since the CPU 401 does not know whether the reason for the connection failure is due to the frequency mismatch or the limit of the maximum number of connected printers on the side of the printer 210, it has no choice but to display a general-purpose error screen as shown in FIG.

According to this embodiment, since the printing apparatus 210 starts the wireless direct mode so that the operating frequency matches that of the mobile terminal 200, it is possible to prevent an error that the frequency does not match and the connection cannot be established when the wireless direct mode is started. In addition, since the printing apparatus 210 displays an error screen on the operation unit 309 when it detects that the frequencies do not match before starting the wireless direct mode, it is possible to notify the user of the error earlier than in the conventional case. Furthermore, there is also the advantage that the wireless direct mode need not be started unnecessarily.
In the present embodiment, the printing device 210 compares frequency information, but wireless LAN standard information such as 802.11n may also be compared. The printing device 210 may compare the wireless LAN standard information and start the wireless direct mode so that the wireless LAN standard information matches. Also, the printing device 210 may compare both the frequency information and the wireless LAN standard information.

<Embodiment 2>
In the first embodiment, NFC two-way communication is used to compare whether the operating frequencies match, but BLE two-way communication may be used to determine whether the operating frequencies match.
When using BLE, data defined by NDEF data is defined as BLE GATT (Generic Attribute Profile) characteristic. For example, as shown in FIG. 14, "command instruction", "operating frequency", "wireless LAN standard", "command instruction result", etc. are defined as characteristics. The parameters that each data can take are the same as in the first embodiment.
The processing flow of this embodiment in the printing apparatus 210 is almost the same as in FIG. The process of receiving NDEF data by NFC in S501 becomes a process of receiving GATT data by BLE. Also, the process of transmitting the response data by NFC in S505 or S507 is transmitted by BLE.
Similarly, in the mobile terminal 200, the processing flow of this embodiment is almost the same as that of FIG. The processing that generated NDEF data in S1001 and S1002 generates BLE GATT data. Further, the data transmission using NFC in S1007 or S1012 is performed using BLE.

By activating the wireless direct mode at a frequency that matches the frequency at which the mobile terminal operates, the printing apparatus can prevent a connection error due to frequency mismatch, and the wireless LAN connection between the printing apparatus and the mobile terminal will not occur. A connection can be established.
