Description

  The present invention relates to an information processing apparatus, a control method for the information processing apparatus, and a program.

  In recent years, mobile terminals called smartphones and tablet PCs have a wireless communication function, and using this wireless communication function, for example, photographs and document data stored in the mobile terminal are transmitted to a printer and printed by a printer. Can be made.

  In order for the portable terminal to perform wireless communication with an apparatus such as a printer, the portable terminal needs to establish wireless communication with a printing apparatus by connecting to an access point, for example. As a method for establishing this wireless communication, a handover using NFC (Near Field Communication) is known (Patent Document 1). The handover is to acquire connection information (for example, SSID) necessary for executing wireless communication using near field wireless communication such as NFC and establish wireless communication based on the acquired connection information. With this handover, it is possible for the user to establish wireless communication between the portable terminal and the external device only by bringing the portable terminal close to the external device such as a printer (just touching it).

  Some external devices act as access points themselves, and direct wireless communication can be established between such external devices and portable terminals. Even in such a form, the above-described handover can be realized.

  In addition, since the mobile terminal stores connection information that has been used to establish wireless communication, the mobile terminal can reconnect to an access point that has been connected, which is convenient for the user. Improves.

JP 2013-157736 A

  The above-described handover is performed in order to temporarily establish wireless communication between the mobile terminal and the external device. In addition, since the mobile terminal can reconnect to the access point once connected, the external device may change the SSID randomly at each connection. As a result, it is possible to prevent a situation in which another mobile terminal that has been connected once connects to the external device first, even though the user of the mobile terminal tries to connect to the external device. . On the other hand, since the mobile terminal stores a randomly generated SSID each time it connects to an external device, a large amount of SSID may be displayed on the SSID selection screen of the mobile terminal. In such a case, the user must search for a desired SSID from a list of a large number of SSIDs, which is a cumbersome operation for the user.

  An object of the present invention is to solve the above-described problems of the prior art.

  A feature of the present invention is to solve the above-described problems of the prior art by deleting temporary connection information from connection information generated and stored every time a connection is made with an external device.

In order to achieve the above object, an information processing apparatus according to an aspect of the present invention has the following arrangement. That is,

Second acquisition means for acquiring current connection information regarding wireless communication to which the information processing apparatus is currently connected;
Of the connection information stored in the storage means, connection information determined by the determination means as connection information for the temporary connection, and the current information acquired by the second acquisition means Control means for controlling to delete connection information that is not connection information from the storage means.

  According to the present invention, there is an effect that a large amount of connection information is not stored by deleting temporary connection information from connection information generated and stored every time a connection is made with an external device. .

[Embodiment 1]
FIG. 1 is a diagram illustrating a configuration of a communication system according to Embodiment 1 of the present invention.

  The communication system according to the first embodiment includes a mobile terminal 100, a printing apparatus 110, an NFC tag 111 provided in the printing apparatus 110, and an access point 120. The printing apparatus 110 may operate as an access point in software and execute wireless communication such as a wireless communication LAN with the mobile terminal 100.

  The portable terminal 100 can execute wireless communication such as a wireless communication LAN. When the user inputs the SSID and security key of the printing apparatus 110 to the portable terminal 100, the portable terminal 100 can connect to the printing apparatus 110 and communicate with the printing apparatus 110 via the wireless communication LAN. Thus, the portable terminal 100 can transmit a print job to an external device such as the printing device 110 via the wireless communication LAN, and the printing device 110 that has received the print job executes printing according to the print job.

  Further, the mobile terminal 100 and the printing apparatus 110 can execute close proximity wireless communication such as NFC. In the first embodiment, the printing apparatus 110 includes an NFC tag 111, and connection information for connecting to the access point 120 (SSID and security key of the access point 120) is stored in the NFC tag 111. The mobile terminal 100 can acquire the information of the NFC tag 111 of the printing apparatus 110 using NFC, and can connect to the access point 120 based on the acquired information. In this way, switching the connection to wireless communication such as a wireless communication LAN using information acquired by proximity wireless communication such as NFC is called handover. By this handover, it is possible for the user to save the trouble of inputting information for connecting to the access point 120 (SSID and security key of the access point 120) to the mobile terminal 100.

  FIG. 7 is a block diagram illustrating a hardware configuration of the NFC tag 111 according to the first embodiment.

  The antenna 701 is connected to the controller 702. The antenna 701 is supplied with electric power from the proximity wireless communication unit 208 (FIG. 2) of the portable terminal 100 by electromagnetic induction, and is used as the operating power of the controller 702. In addition, the wireless communication unit 208 operates as an antenna for wireless communication. The controller 702 communicates with the mobile terminal 100 via the antenna 701. In addition, a process for reading and writing an instruction for reading and writing by communication to the memory 703 is performed. As a result, information of the printing apparatus 110 such as a MAC address, which will be described later, can be held, and the information can be notified to the outside via the antenna 701 as necessary.

  FIG. 2 is a block diagram illustrating a hardware configuration of the mobile terminal 100 according to the first embodiment. In addition, although the portable terminal 100 which concerns on Embodiment 1 assumes apparatuses, such as a smart phone and a tablet PC, as long as it is an information processing apparatus which can perform wireless communication, another apparatus may be sufficient as it.

  The CPU 201 expands and executes the control program stored in the ROM 202 and the flash memory 204 in the RAM 203 and executes various processes for controlling the operation of the mobile terminal 100. The ROM 202 stores a control program. The RAM 203 is used as a temporary storage area such as a main memory and a work area for the CPU 201. The flash memory 204 stores various data such as photographs and electronic documents. An OS (Operating System) 310 and a print application 300 described later are also stored in the flash memory 204. An RTC (Real Time Clock) 205 measures the time instructed by the CPU 201 and the current time.

  In addition, although the portable terminal 100 shall perform each process shown to the flowchart mentioned later here by one portable terminal 100, another aspect may be sufficient. For example, a plurality of CPUs may cooperate to execute each process shown in a flowchart described later.

  The operation panel 206 has a touch panel function that can detect a user's touch operation, and displays various screens provided by the OS 310 and the print application 300. The user can input a desired operation instruction to the mobile terminal 100 by inputting a touch operation on the operation panel 206. In addition, the mobile terminal 100 includes a hardware key (not shown), and the user can input an operation instruction to the mobile terminal 100 using the hardware key.

  The speaker 207 and the microphone 208 are used when the user makes a call with another mobile terminal (mobile phone) or a fixed phone. The camera 209 captures an image according to a user's imaging instruction. Photo data captured by the camera 209 is stored in a predetermined area of the flash memory 204.

  The near field communication unit 210 performs near field communication such as NFC. In the first embodiment, the printing apparatus 110 includes the NFC tag 111. When the user brings the mobile terminal 100 close to the NFC tag 111 of the printing apparatus 110, the proximity wireless communication unit 210 and the NFC tag 111 of the printing apparatus 110 establish proximity wireless communication. Information on the tag 111 is acquired. The close proximity wireless communication performed by the close proximity wireless communication unit 210 is not limited to NFC, and may be, for example, Bluetooth (registered trademark).

  The wireless communication unit 211 performs wireless communication via a wireless communication LAN or the like. In the case of the portable terminal 100, by using handover, wireless communication by the wireless communication unit 211 can be realized with a simple operation for the user. Specifically, the wireless communication unit 211 connects to the access point 120 using connection information (SSID and security key of the access point 120) acquired by the close proximity wireless communication unit 210 from the NFC tag 111 of the printing apparatus 110. Then, it is possible to communicate with a device connected to the access point 120 via the access point 120.

  FIG. 3 is a block diagram illustrating the software configuration of the mobile terminal 100 according to the first embodiment. The software shown in FIG. 3 indicates software functions realized by the CPU 201 reading a control program stored in the ROM 202 or the flash memory 204.

  The OS 310 is software for controlling the operation of the mobile terminal 100 as a whole. The control unit 311 controls the overall operation of the OS 310. Various applications including a print application 300 described later can be installed in the portable terminal 100. The control unit 311 exchanges information with these applications, changes the screen displayed on the operation panel 206 in accordance with an instruction received from the application, and executes wireless communication by the wireless communication unit 211.

  Next, an outline of the printing function and screen transition realized by the printing application 300 will be described with reference to FIG. Each screen shown in FIG. 6 shows a screen example displayed on the operation panel 206 by the print application 300.

  FIG. 6A is a diagram illustrating an example of a print screen displayed on the mobile terminal 100 according to the first embodiment.

  Here, a list of documents stored in the flash memory 204 is displayed. The print screen shows a case where four documents 601 to 604 are displayed as an example. On this print screen, the user selects a document to be printed.

  FIG. 6B is a diagram showing a print screen displayed when the user selects the document 601 on the print screen of FIG. On this print screen, a preview image 611 of the document selected by the user is displayed. Here, when the user wants to change the print setting, the user selects the button 612. When the user wants to return to the document list screen of FIG. 6A, the user selects the icon 613.

  When the user brings the portable terminal 100 close to (touches) the NFC tag 111 of the printing apparatus 110 while the print screen of FIG. 6B is displayed, the proximity wireless communication unit 210 causes the NFC tag 111 of the printing apparatus 110 to be touched. The connection information stored in is read. In the first embodiment, the NFC tag 111 of the printing apparatus 110 stores connection information for the wireless communication unit 211 to perform wireless communication with the printing apparatus 110. The wireless communication unit 211 can execute wireless communication with the printing apparatus 110 based on the connection information acquired by the proximity wireless communication unit 210 reading the NFC tag 111 of the printing apparatus 110.

  When the wireless communication unit 211 of the portable terminal 100 connects to the access point (access point 120 or printing device 110) indicated by the connection information in this way, the print application 300 generates a print job and transmits the print job to the printing device 110. . The connection information acquired by the wireless communication unit 211 using close proximity wireless communication also includes the IP address of the printing apparatus 110, and transmits the print job to the printing apparatus 110 with this IP address as the destination.

  FIG. 6C illustrates an example of a screen displayed on the operation panel 206 when the print application 300 is transmitting a print job. Here, a message “processing” indicating that the print job is being transmitted is displayed. When transmission of the print job is completed, the message indicating that this processing is in progress is deleted.

  The series of flow of the printing function realized by the printing application 300 has been described above. Since this printing function is realized by touching the NFC tag 111 of the printing apparatus 110 with the mobile terminal 100, it is called a touch printing function.

  FIG. 4 is a block diagram illustrating a hardware configuration of the printing apparatus 110 according to the first embodiment. Here, the printing apparatus 110 is described as an example of a multi-function processing apparatus (MFP) having a copy function, a scan function, a printing function, a box function, a facsimile transmission / reception function, etc. Of course.

  The CPU 401 expands a program stored in the large-scale storage device 412 such as the ROM 402 or the hard disk in the RAM 403, executes the program, and comprehensively controls each device connected to the system bus 415. The RAM 403 functions as a main memory, work area, and the like for the CPU 401. The panel interface 407 inputs instructions from various buttons provided in the printing apparatus 110, the operation panel 408, and the like. The display unit interface 409 controls display on the display unit 410. A disk controller (DKC) 411 controls reading and writing of data to and from a large-scale storage device 412 such as an HDD.

  A network interface card (NIC) 405 exchanges data bidirectionally with other network devices or file servers via the network 10. When operating in the infrastructure mode, the wireless communication module (WLAN) 404 is connected to the network 10 via an access point, and exchanges data bidirectionally with other network devices, file servers, and the like. When operating in the soft AP mode, the printing apparatus 110 operates as an access point and can be directly connected to the mobile terminal by wireless communication. The printer unit 413 prints an image on a sheet such as paper by an electrophotographic method, for example. The scanner 414 reads a document and generates image data of an image of the document. As described above, the NFC tag 111 stores information on applications started from the controller 702, wireless LAN handover, and the like. The portable terminal 100 uses the proximity wireless communication unit 210 to read connection information stored in the NFC tag.

  FIG. 5 is a block diagram illustrating a software configuration of the printing apparatus 110 according to the embodiment. The software is stored in the ROM 402 or the HDD 412, and is expanded in the RAM 403 and executed by the CPU 401, thereby realizing the functions shown in this block diagram.

  The network setting unit 501 sets information to be written in the NFC tag 111. Specifically, wireless LAN connection information and device name information are set as parameters. The wireless LAN connection information includes an SSID and a password. The SSID is randomly generated every time the wireless LAN is disconnected. The NFC tag writing unit 502 writes the parameters set by the network setting unit 501 to the NFC tag 111.

  FIG. 8 is a diagram illustrating an example of information written to the NFC tag 111 in the first embodiment.

  The activated application information 801 is an application name that is activated when the mobile terminal 100 is touched on the NFC tag 111. FIG. 8 shows that a print application named “com.example.printapp” is activated.

  Wi-Fi connection information 802 indicates connection information to the wireless network. This connection information includes the SSID and password of the access point 120 that can be connected to the printing apparatus 110. Here, the randomly generated temporary SSID is stored in a predetermined format. In the first embodiment, “DIRECT_xx_abc10” is stored, and the portion “xx” in this is randomly generated.

  Network connection information 803 indicates the MAC address of the printing apparatus 110. In the first embodiment, only the MAC address is described, but it may be a combination of information that can distinguish the printing apparatus 110 such as the IP address and UUID of the printing apparatus 110.

  The device name information 804 indicates the name of the printing apparatus 110, here “Printer01”.

  FIG. 9 is a flowchart for explaining processing when the mobile terminal 100 according to the first embodiment transmits a print job to the printing apparatus 110. The processing shown in this flowchart is achieved by the CPU 201 developing a program stored in the ROM 202 or the flash memory 204 in the RAM 203 and executing it.

  This process is started when the user of the mobile terminal 100 touches the NFC tag 111 of the printing apparatus 110 while the user selects the document to be printed on the screen of FIG.

  First, in step S <b> 901, the CPU 201 acquires connection information from the NFC tag 111 via the proximity wireless communication unit 210. This connection information includes an SSID temporarily generated by the printing apparatus 110 in order to perform direct wireless communication between the mobile terminal 100 and the printing apparatus 110. When the connection information is acquired from the NFC tag 111 via the proximity wireless communication unit 210 in this way, the process proceeds to S902, and the CPU 201 stores the acquired connection information in the flash memory 204. In step S903, the CPU 201 connects to the access point 120 indicated by the connection information stored in step S902. In this way, wireless communication between the portable terminal 100 and the printing apparatus 110 is established. In step S <b> 904, the CPU 201 transmits a print job to the printing apparatus 110. In the first embodiment, the print application 300 generates a print job for printing the document selected by the user on the print screen in FIG. 6A, and the generated print job is transmitted to the printing apparatus 110 in step S904. . The printing apparatus 110 that has received the print job transmitted in S904 executes print processing based on the received print job. When the transmission of the print job is completed in this way, application termination processing is executed.

  The mobile terminal 100 according to the first embodiment searches for surrounding access points when connected to a wireless LAN, and displays an access point selection screen based on the search result. When the user selects a desired access point on the selection screen, the mobile terminal 100 connects to the selected access point. Note that the designation of the connection destination access point is not limited to the designation from the selection screen based on the search result. For example, the user may directly input the SSID or connection key of the access point to the mobile terminal 100. good.

  The storage unit 312 of the OS 310 stores connection information that is connected when the wireless communication unit 211 executes wireless communication. Here, as the connection information, specifically, information on the access point selected on the selection screen and information on the access point acquired from the NFC tag 111 by the close proximity wireless communication unit 210 by close proximity wireless communication are stored.

  The mobile terminal 100 holds history information connected to the wireless LAN, and displays a list of access points connected in the past on the history screen. This history screen is displayed based on information stored in the storage unit 312.

  The connection information acquired from the NFC tag by the close proximity wireless communication is information temporarily used for printing. If the storage unit 312 stores these temporarily used connection information each time the touch printing function by the print application 300 is executed, a large amount of connection information is stored in the storage unit 312. In this way, when a large amount of temporarily used connection information is stored in the storage unit 312, for example, a large amount of information is displayed on the history screen, which deteriorates the appearance.

  In addition, the number of pieces of connection information stored in the storage unit 312 may reach the maximum number that can be stored in the storage unit 312. In this case, if the connection information acquired from the NFC tag by the proximity wireless communication is newly stored, other important connection information, for example, the connection information indicating the access point used by the user at home may be deleted. User convenience is reduced.

  Therefore, in the first embodiment, the connection information acquired from the NFC tag by the close proximity wireless communication, that is, the connection information used temporarily is deleted. By this process, it is possible to prevent the appearance of the history screen from being deteriorated or the connection information stored from increasing, so that important connection information is not deleted instead.

  FIG. 10 is a flowchart for describing processing executed when the print application 300 of the mobile terminal 100 according to the first embodiment ends. The processing shown in this flowchart is achieved by the CPU 201 developing a program stored in the ROM 202 or the flash memory 204 in the RAM 203 and executing it.

  At this time, as a work area, all_SSID_list (number of elements: all_SSID_list_num) that stores a list of SSIDs acquired from the OS 310, tmp_SSID_list (number of elements: tmp_SSID_list_num) that stores a list of temporarily connected SSIDs, and what number in the list I and k are provided in the RAM 203 as variables indicating elements.

  First, in step S1001, the CPU 201 determines whether or not the application is to be ended. If the application is to be ended, the process proceeds to step S1002, and if not, the process returns to step S1001. In step S <b> 1002, the CPU 201 acquires an SSID list from the OS 310 and stores it in the SSID list all_SSID_list in the RAM 203. In step S1003, the CPU 201 initializes the variable i in the RAM 203 to “0”, and then advances to step S1004. In step S1004, the CPU 201 determines whether the i-th SSID in the SSID list all_SSID_list is a temporary SSID. In the first embodiment, if the name of the SSID includes a predetermined character string, it is determined as a temporary SSID. Note that the method for determining the temporary SSID is not limited to this. For example, if it is a specific IP address, it may be determined as a temporary SSID, or included in information acquired by close proximity wireless communication such as NFC or Bluetooth. The determination may be made based on the flag. Alternatively, another determination method may be used.

  If the CPU 201 determines in step S1004 that it is a temporary SSID, the process advances to step S1005. If not, the process advances to step S1006. In step S1005, the CPU 201 stores the SSID determined to be temporary in tmp_SSID_list that stores a list of temporarily connected SSIDs, and proceeds to step S1006. In step S1006, the CPU 201 increments the variable i and proceeds to step S1007. In step S1007, the CPU 201 determines whether the number of elements of all_SSID_list (all_SSID_list_num) matches the variable i. That is, it is determined whether or not all elements in the SSID list acquired in S1002 have been examined. If they match, that is, if it is determined that all elements have been examined, the process proceeds to S1008, and if not, the process returns to S1004.

  In step S1008, the CPU 201 initializes a variable k for counting the number of deleted elements to “0”, and proceeds to step S1009. In step S1009, the CPU 201 instructs the OS 310 to delete tmp_SSID_list [k] and proceeds to step S1010. In step S1010, the CPU 201 increments the variable k and proceeds to step S1011. In step S1011, the CPU 201 determines whether tmp_SSID_list_num matches the variable k. That is, it is determined whether an instruction to delete all elements of the temporary SSID list tmp_SSID_list has been issued to the OS 310. If all elements are not instructed to be deleted, the process returns to step S1009. If all elements are instructed to be deleted, the process ends.

  In the first embodiment, all SSIDs determined to be temporary SSIDs are deleted. However, in consideration of the processing load of the OS, temporary SSIDs may be deleted only for a predetermined number (for example, five) instead of all cases. The predetermined number may be designated by the user.

  As described above, according to the first embodiment, by deleting the SSID determined to be a temporary SSID, for example, the appearance of the history screen is deteriorated or the stored connection information is increased. Instead, important connection information can be prevented from being deleted.

  In the first embodiment, the connection information deletion process is executed when the application is terminated. For example, the temporary connection information may be deleted when the application is activated, when a new connection is established, or when the connection is disconnected.

[Embodiment 2]
Next, Embodiment 2 of the present invention will be described. In the second embodiment, in addition to the above-described configuration, the currently used SSID is considered not to be deleted because it is considered to be connection information still being used by the user. Hereinafter, this process will be described in detail. Note that the system configuration according to the second embodiment and the hardware configurations of the mobile terminal 100 and the printing apparatus 110 are the same as those of the first embodiment, and a description thereof will be omitted.

  FIG. 11 is a flowchart for explaining processing executed when the print application 300 of the mobile terminal 100 according to the second embodiment ends. The processing shown in this flowchart is achieved by the CPU 201 developing a program stored in the ROM 202 or the flash memory 204 in the RAM 203 and executing it.

  At this time, as a work area, there are all_SSID_list (number of elements: all_SSID_list_num) storing a list of SSIDs acquired from the OS 310, and current_SSID holding SSID information currently connected. Further, tmp_SSID_list (number of elements: tmp_SSID_list_num) for storing a list of temporarily connected SSIDs and i, j, and k as variables indicating the number of elements in the list are provided in the RAM 203.

  First, in step S1101, the CPU 201 determines whether or not the application is to be ended. If the application is to be ended, the process proceeds to step S1102, and if not, the process returns to step S1101. In step S1102, the CPU 201 acquires a list of SSIDs from the OS and stores the list in the all_SSID_list of the RAM 203. The process advances to step S1103, and the CPU 201 initializes the variable i in the RAM 203 to “0” and advances to step S1104. In step S1104, the CPU 201 determines whether the i-th SSID in the all_SSID_list is a temporary SSID. In the second embodiment, it is determined that the SSID name is a temporary SSID if the name includes a predetermined character string. Note that the method for determining the temporary SSID is not limited to this. For example, if it is a specific IP address, it may be determined as a temporary SSID, or included in information acquired by close proximity wireless communication such as NFC or Bluetooth. The determination may be made based on the flag. Alternatively, another determination method may be used.

  If the CPU 201 determines in step S1104 that it is a temporary SSID, the process advances to step S1105; otherwise, the process advances to step S1106. In step S1105, the CPU 201 stores the SSID determined to be temporary in tmp_SSID_list that stores a list of temporarily connected SSIDs, and proceeds to step S1106. In step S1106, the CPU 201 increments the variable i and proceeds to step S1107. In step S1107, the CPU 201 determines whether the number of elements of all_SSID_list (all_SSID_list_num) matches the variable i. That is, it is determined whether or not all the elements of the SSID list acquired in S1102 have been examined. If they match, that is, if it is determined that all the elements have been examined, the process proceeds to S1108. If not, the process returns to S1104.

  In step S1108, the CPU 201 acquires the currently connected SSID from the OS 310, stores it in the current_SSID, and proceeds to step S1109. In step S1109, the CPU 201 initializes the variable j and proceeds to step S1110. In step S1110, the CPU 201 determines whether tmp_SSID_list [j] and current_SSID match. That is, it is determined whether or not the SSID determined to be temporary matches the currently connected SSID. If it is determined that they match, the process proceeds to S1113, and if not, the process proceeds to S1111. In step S1111, the CPU 201 increments the variable j and proceeds to step S1112. The CPU 201 determines whether tmp_SSID_list_num and the variable j match. That is, it is determined whether or not all the elements of the temporarily connected SSID list have been examined. If they match, that is, if all the elements have been examined, the process proceeds to S1115, and if not, the process returns to S1110.

  In S1113, the CPU 201 deletes the currently connected SSID from the temporary SSID list tmp_SSID_list [j], and proceeds to S1114. In step S1114, the CPU 201 deletes one element tmp_SSID_list [j] of the temporary SSID list, so decrements tmp_SSID_list_num (−1) and proceeds to step S1115.

  In step S1115, the CPU 201 initializes the variable k and proceeds to step S1116. In step S1116, the CPU 201 instructs the OS to delete tmp_SSID_list [k], and proceeds to step S1117. In S1117, the CPU 201 increments the variable k and proceeds to S1118. In step S1118, the CPU 201 determines whether tmp_SSID_list_num matches the variable k. That is, it is determined whether or not an instruction to delete all elements of the temporary SSID list tmp_SSID_list after deleting the currently connected SSID has been issued to the OS. If all elements are not instructed to be deleted, the process returns to S1116. If all elements are instructed to be deleted, the process is terminated.

  In the second embodiment, all temporary SSIDs other than the currently used SSID are deleted. However, in consideration of the processing load of the OS, a predetermined number (for example, five) of temporary SSIDs may be deleted instead of all cases. The predetermined number may be specified by the user via the operation panel 206, for example.

  As described above, according to the second embodiment, by deleting the SSID determined to be a temporary SSID, for example, the appearance of the history screen is deteriorated or the stored connection information is increased. Instead, important connection information can be prevented from being deleted. Furthermore, by deleting SSIDs other than the SSID currently used, it is possible to leave connection information that is still being used by the user.

  In the second embodiment, the temporary connection information deletion process is executed when the application is terminated. However, it may be executed when the application is activated, when a new connection is established, or when the connection is broken.

  In the first and second embodiments, the SSID starting with a predetermined character string (for example, “Direct”) is used as a condition for determining a temporary SSID. However, for example, when a fixed SSID of a certain product includes this predetermined character string, it is determined as a temporary SSID in this embodiment. Therefore, as a condition for determining the temporary SSID, for example, a predetermined condition such as an SSID format or a specific IP address may be used. Alternatively, as described above, it may be a condition that information acquired by close proximity wireless communication such as NFC or Bluetooth is included.
