Description

  The present invention relates to a mobile communication terminal device, and more particularly to connection processing of a short-range wireless communication function.

  A process in which mobile communication terminal devices having a short-range wireless communication function such as a wireless LAN and Bluetooth (registered trademark, Bluetooth) directly communicate with each other is known, and is called, for example, an ad hoc mode communication. Here, the number of portable communication terminal devices that directly communicate simultaneously is not limited to two, and may be three or more.

  In the ad hoc mode communication, a device (hereinafter referred to as a client device) that starts communication communicates information (hereinafter referred to as a parameter) necessary to start communication with a communication partner device (hereinafter referred to as a server device). Is often required for each communication. The parameters are, for example, an identifier for identifying the server device, and password information used for authentication when logging in to the server device, and are an SSID and a WEP key, respectively.

  Here, it does not necessarily mean that the server device provides a service to the client device. For example, when transferring a file such as an address book between a server device and a client device, the transfer direction may be from the server device to the client device, or vice versa. When the server device and the client device perform chat processing, the chat function operates on both devices. In short, the client device is a device that logs in to the server device.

  Note that, for example, in communication via an access point, called infrastructure mode communication, the client device does not necessarily need to know the parameters of the server device each time communication is started. I remember it.

  As a method for the client device to obtain the parameters of the server device, it is first known that the user of the client device manually inputs using the input device. However, in this method, the user makes an input operation incorrectly. It is possible and not preferred.

  Therefore, there is a demand for a method in which the client device obtains parameters without complicated operations by the user. For example, the server device displays its parameters on the display unit of the device, and the client device displays the parameters. A parameter can be obtained by photographing the measured parameter with a camera.

  In addition, when a server apparatus displays a parameter, you may display as a character. When displayed as characters, the client device captures and recognizes the displayed characters to obtain parameters. Further, the server device converts the parameter into a barcode and displays it, and the client device captures and converts the displayed barcode to obtain the parameter.

Further, the server device converts the parameter into a two-dimensional barcode such as a QR code (registered trademark) and displays it, and the client device captures and converts the displayed two-dimensional barcode to obtain the parameter. It is known (for example, refer to Patent Document 1).
JP 2004-274520 A (2nd page, FIG. 2)

  However, the method disclosed in Patent Document 1 described above has a problem that the user of the client device needs to know in advance that the parameters of a certain server device are provided by a two-dimensional barcode. . In addition, when there are a plurality of methods for obtaining parameters, it is necessary for the client device user to determine which method is appropriate in consultation with the server device user, which is troublesome. It was.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a mobile communication terminal device capable of notifying parameters by an appropriate method.

  In order to achieve the above object, a mobile communication terminal device according to the present invention communicates with a counterpart terminal using short-range wireless communication means and short-range wireless communication means, and communicates with the counterpart using the short-range wireless communication means. And a parameter output unit that outputs a parameter used for the authentication by the short-range wireless communication unit, wherein the short-range wireless communication unit outputs the parameter output Information for identifying the means is reported.

  The portable communication terminal device of the present invention includes parameter input means for inputting parameters, and short-range wireless communication means for communicating by connecting the parameters input from the parameter input means to the server device as authentication information. In the portable communication terminal device, the short-range wireless communication unit controls the parameter input unit to input the parameter output from the parameter output unit identified by information notified by the server device, The input parameter is connected to the server device as the authentication information.

  ADVANTAGE OF THE INVENTION According to this invention, the portable communication terminal device which can notify a parameter with an appropriate method can be provided.

  Embodiments of a mobile communication terminal device according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a communication system in which mobile communication terminal devices to which a mobile communication terminal device according to an embodiment of the present invention is applied communicate directly.

Note that a description of processing when the configurations of these apparatuses are different will be added as appropriate.

  FIG. 2 is a block diagram showing a configuration of mobile communication terminal apparatus 100. The mobile communication terminal apparatus 100 includes a control unit 101 that controls the entire apparatus, a mobile communication network communication unit 102 that includes an antenna that transmits and receives radio waves to and from a base station (not shown) belonging to the mobile communication network, The transmission / reception unit 103, the speaker 104a used for receiving, the microphone 104b used for transmitting, the call unit 104c, the display unit 105 for presenting information to the user, and an operation instruction from the user are input.

And an infrared communication unit 125 including an infrared light receiving unit, and a storage medium connection unit 131.

  The parameter storage unit 108 stores the parameter 108a. The parameter 108a is information necessary for logging in to the mobile communication terminal device 100 via the wireless LAN communication unit 123, but is not limited thereto. Information necessary for logging in to another mobile communication terminal device 100 via the wireless LAN communication unit 123 of the device may be included.

  A removable storage medium such as an SD card or a USB memory is connected to the storage medium connecting unit 131. Information stored in a storage medium attached to the storage medium connection unit 131 is read and / or written by each unit of the apparatus.

  In FIG. 2, transmission / reception of signals among many processing units is illustrated as passing through the control unit 101, but is not limited thereto. The apparatus is configured to operate in accordance with the control of the control unit 101, and each unit may directly send and receive signals.

  A part or all of each processing unit may be constituted by a CPU and a program used by the CPU. And the control part 101 is comprised from CPU and the program utilized by the CPU, and may perform OS function.

  The operation of each part of mobile communication terminal apparatus 100 according to the embodiment of the present invention configured as described above will be described with reference to FIG. The mobile communication network communication unit 102 transmits the received high frequency signal to the transmission / reception unit 103. In addition, a high-frequency signal output from the transmission / reception unit 103 is transmitted.

  The transmission / reception unit 103 amplifies, frequency-converts and demodulates the high-frequency signal from the mobile communication network communication unit 102, transmits the digital audio signal obtained thereby to the call unit 104c, and transmits a control signal to the control unit 101. The parameter is transmitted to the wireless LAN communication unit 123. Further, the digital audio signal output from the call unit 104c, the control signal output from the control unit 101, and the parameter 108a output from the wireless LAN communication unit 123 are modulated, frequency converted and amplified to obtain a high frequency signal. , It is transmitted to the mobile communication network communication unit 102.

  The call unit 104c converts the digital audio signal output from the transmission / reception unit 103 into an analog audio signal, amplifies the signal, and sends the analog audio signal to the speaker 104a. Further, the analog audio signal output from the microphone 104 b is amplified, converted into a digital audio signal, and transmitted to the transmission / reception unit 103.

  The display unit 105 is a display unit of an LCD, for example, and starts a display operation when activated by the control unit 101. The same display operation is continued until a new screen is activated by the control unit 101 in response to an input signal from the input device 106 and depending on the operation of each unit.

  The input device 106 includes a plurality of key switches, and notifies the control unit 101 of a code signal for identifying the key switch operated by the user by an activation signal from the control unit 101.

  The camera 107 is activated by a predetermined key operation of the input device 106 and photographs a two-dimensional barcode. Then, the photographed two-dimensional barcode image is transmitted to the two-dimensional barcode analysis unit 122.

  When communicating via the wireless LAN communication unit 123 of the mobile communication terminal device 100, the two-dimensional barcode creating unit 121 connects to the mobile communication terminal device 100 and sets parameters 108a necessary for logging in to the two-dimensional barcode. The data is converted into a code, and the converted two-dimensional barcode is displayed on the display unit 105. The parameter 108a is stored in the parameter storage unit 108 as described above.

  The two-dimensional barcode analysis unit 122 receives a two-dimensional barcode image signal photographed by the camera 107 from the camera 107, analyzes it, and converts the two-dimensional barcode image into a parameter. Then, the obtained parameters are transmitted to the wireless LAN communication unit 123.

  For example, the wireless LAN communication unit 123 performs wireless LAN communication according to the IEEE 802.11 standard. That is, when the own device operates as a client device, it communicates by logging in to the server device using parameters. Further, when the own device operates as a server device, the parameter transmitted from the client device is compared with the parameter 108a of the own device stored in the parameter storage unit 108, and communication is performed if they match. If they do not match, no communication is made.

  When the local device operates as a client device, the wireless LAN communication unit 123 receives from the mobile communication network communication unit 102, receives a predetermined key operation of the input device 106, receives from the two-dimensional barcode analysis unit 122, and receives from the Bluetooth communication unit 124. The parameter of the server apparatus is input by any means among reception, reception from the infrared communication unit 125, and reading from the storage medium connected to the storage medium connection unit 131.

  The wireless LAN communication unit 123 may store the parameter obtained by the above method in the parameter storage unit 108 as the parameter 108a. Then, the parameter may be obtained by reading the parameter 108 a stored in the parameter storage unit 108. As will be described later, the parameter 108a is an identifier of a device and personal identification information when logging in to the device via the wireless LAN communication unit 123. If the same identifier is already stored as the parameter 108a, the parameter 108a The LAN communication unit 123 updates and stores the password information.

  The wireless LAN communication unit 123 includes means for obtaining parameters of the own device regardless of whether the own device operates as a client device or a server device when the own device is not communicating with another device. May send a beacon. Here, the means for obtaining a parameter is a means for the server apparatus to output the parameter 108a when the own apparatus operates as a client apparatus. When the device itself operates as a server, the device itself is a means for outputting the parameter 108a.

  Further, the wireless LAN communication unit 123 outputs the parameter 108 a of the own device via the mobile communication network communication unit 102, via the Bluetooth communication unit 124 and / or via the infrared communication unit 125. Sometimes.

  In addition to or in place of this, the wireless LAN communication unit 123 causes the display unit 105 to display the parameter 108a of the own device as characters, or controls the two-dimensional barcode creation unit 121 to set the parameter 108a of the own device. May be output by displaying on the display unit 105 as a two-dimensional barcode. Further, in addition to or instead of the above, the wireless LAN communication unit 123 may output the parameter 108a of its own device by storing it in the storage medium via the storage medium connection unit 131.

  The Bluetooth communication unit 124 performs wireless communication by the Bluetooth (R) method. Authentication processing is performed for this wireless communication. And when the parameter of another apparatus is received by the communication, the received parameter is transmitted to the wireless LAN communication unit 123.

  The infrared communication unit 125 performs infrared communication according to the IrDA standard, for example. Authentication processing may be performed for this infrared communication. And when the parameter of another apparatus is received by the communication, the received parameter is transmitted to the wireless LAN communication unit 123.

  An operation in which the wireless LAN communication unit 123 of the mobile communication terminal device 100 according to the embodiment of the present invention configured as described above notifies the parameter by an appropriate method will be described.

  FIG. 3 shows an example of the parameter 108a. The parameter 108a includes information in which an identifier 108b, personal identification information 108c, and a parameter flag 108d of the device itself are associated. The identifier 108b is an identifier of the mobile communication terminal device 100 that is used when logging in to the mobile communication terminal device 100 via the wireless LAN communication unit 123 regardless of whether it is the own device or another device. The personal identification information 108 c is personal identification information used when logging in to the mobile communication terminal apparatus 100 identified by the identifier 108 b via the wireless LAN communication unit 123.

  The parameter flag 108d of the own device is information “parameter of own device” in one parameter 108a, and indicates that the parameter 108a is a parameter related to the own device. The other parameters 108a are not stored with values, and these parameters 108a indicate parameters related to other devices.

(Mode in which the server device transmits a beacon)
First, the operation of the wireless LAN communication unit 123 in a form in which the mobile communication terminal device 100 serving as a server device transmits a beacon will be described.

  FIG. 4 shows a flowchart of the operation of the wireless LAN communication unit 123 in a form in which the mobile communication terminal device 100 as a server device transmits a beacon, and the left side of the figure shows the operation of the wireless LAN communication unit 123 of the device as a client device. The right side of the figure shows the operation of the wireless LAN communication unit 123 of the device serving as the server device.

  Both wireless LAN communication units 123 are activated by both control units 101 (steps S123a and T123a), and the wireless LAN communication unit 123 of the client device detects the presence / absence of each processing unit and the presence / absence of an operation abnormality. (Step S123b). As a result of this detection, the wireless LAN communication unit 123 of the client device can use which means by the wireless LAN communication unit 123 of the client device as a means to acquire parameters necessary for logging in to the server device. Recognize

  The wireless LAN communication unit 123 of the server device primarily selects a means for notifying the client device of the parameter 108a necessary for logging in to the own device (step T123b). For this selection, the wireless LAN communication unit 123 stores the parameter notification unit priority in the wireless LAN communication unit 123. The output of the parameter 108a of the own device when operating as a server device and the input of the parameter 108a of the server device when operating as a client device to be described later are collectively referred to as parameter notification.

  FIG. 5 shows an example of parameter notification means priority. The parameter notification means priority 123a includes information in which the parameter notification means 123b, the security 123c, the effort 123d, the required time 123e, the distance 123f between them, and the penetration rate 123g are associated with each other.

  The parameter notifying unit 123b is one of information of “bar code”, “manual input”, “storage medium”, “infrared communication”, “Bluetooth communication”, and “mobile communication network communication”, and notifies the parameter. Means. FIG. 5 shows an example in which all of these means are stored.

  Each of the above information is created by the 2D barcode creating unit 121, means for analyzing the displayed 2D barcode by the 2D barcode analyzing unit 122, means for inputting by a predetermined key operation of the input device 106, Means through a storage medium connected to the storage medium connection unit 131, means by communication of the infrared communication unit 125, means by communication of the Bluetooth communication unit 124, and means by communication of the mobile communication network communication unit 102 are shown. Note that in a device that does not have these processing units, the means using the device is not stored.

  The security 123c is configured to prevent information leakage known by a device or person who should not know the parameter when the parameter is notified by the means stored in the parameter notification unit 123b, that is, a device or person other than the client device and the user of the client device. A low number indicates whether the probability is high or low, and a small number indicates a low probability.

  In the example illustrated in FIG. 5, the parameter notification unit 123b that is “barcode”, “manual input”, and “storage medium” that requires an operation by the user of the client device is stored as having high security 123c. ing. In particular, if the parameter notification means 123b is “barcode”, there is no possibility of information leakage due to loss of the storage medium, and there is no possibility of information leakage due to visual recognition of the manual input operation. It is remembered that the possibility is low.

  In addition, the parameter notification means 123b, which is “infrared communication”, “Bluetooth communication”, and “mobile communication network communication”, in which parameter notification is performed by communication and does not require operation of the user of the client device, has security 123c. It is remembered that it is low. This is because there is no possibility that information is leaked by an operation that the user is not aware of. In addition, it is stored that the possibility of information leakage is relatively low when strict authentication is performed during these communications, and that the possibility of information leakage is high when authentication is not performed.

  The effort 123d indicates the number and types of operations necessary for the operation of the user of the client device when the parameters are notified by the means stored in the parameter notification unit 123b, and a small number indicates the number and types of the operations. Indicates less. When the parameter notification is performed by communication, the effort 123d is small. However, since the parameter notification means 123b, which is “infrared communication”, has high directivity of infrared rays, it is necessary to face the surface of the client device that transmits and receives infrared light and the surface of the server device that transmits and receives infrared light. Therefore, the labor 123d is relatively large.

  In the example shown in FIG. 5, the parameter notification means 123 b that is “infrared communication”, “Bluetooth communication”, and “mobile communication network communication”, in which parameter notification is performed by communication and does not require operation of the user of the client device. It is stored that the effort 123d is small. Among these communications, “infrared communication” indicates that the user needs to appropriately arrange the relative positions of the client device and the server device, and therefore, the number and types of the necessary operations are relatively large.

  On the other hand, for the parameter notification means 123b, which is “barcode”, “manual input”, and “storage medium” that requires operation by the user of the client device for parameter notification, it is stored that the effort 123d is large. ing. Among these means, “barcode” indicates that only the operation of photographing the displayed two-dimensional barcode is necessary, and the number and types of the necessary operations are relatively small.

  The effort 123d indicates the number of operations and the number of types necessary for the user operation of the client device, but simultaneously indicates the number of operations and the number of types necessary for the user operation of the server device. It is also good. Further, in addition to or instead of this effort 123d, the parameter notification means priority 123a may include information indicating the number of operations and the number of types necessary for the operation of the user of the server device. .

  The required time 123e indicates the length of time required for parameter notification by the means stored in the parameter notification means 123b, and a small number indicates that the time is short. As shown in an example in FIG. 5, a short required time 123e, that is, a short required time corresponds to a small amount of effort 123d, that is, a small number or type of operations by the user. If the means 123b is "infrared communication", since the communication is not authenticated, it is stored that the required time 123e is small.

  The distance 123f between the two indicates the length of the distance allowed between the client device and the server device when performing parameter notification by the means stored in the parameter notification means 123b, and a small number indicates that the distance is long. Show.

  As shown in an example in FIG. 5, parameter notification means such as “infrared communication”, “Bluetooth communication”, and “mobile communication network communication”, in which parameter notification is performed by communication and does not require operation of the user of the client device. For 123b, the distance 123f between them is generally small, that is, a long distance is allowed. However, for the parameter notification means 123b that is “manual input”, the parameter 108a can be manually input after being communicated by, for example, a call via the call unit 104c, so the distance 123f between the two is relatively small. .

  The penetration rate 123g indicates whether or not the mobile communication terminal device 100 provided with a processing unit for performing parameter notification by means stored in the parameter notification unit 123b is spreading, and a small number is spreading. Indicates that

  In the example shown in FIG. 5, the parameter notification means 123b, which is “manual input” and “mobile communication network communication”, indicates that the diffusion rate 123g is small, that is, the diffusion is progressing. This is because it is essential that the mobile communication terminal apparatus 100 has a mobile communication network communication function and an input function. On the other hand, the parameter notification means 123b, which is “infrared communication” and “Bluetooth communication”, indicates that it has not necessarily spread.

  Returning to the description of the operation of the wireless LAN communication unit 123 with reference to FIG. The wireless LAN communication unit 123 of the server device stores one or a plurality of parameter notification units 123b that are stored in the parameter notification unit priority 123a in step T123b, that is, appropriate among the parameter notification units 123b operable in the server device. After primary selection of the means, information identifying the selected parameter notification means 123b is included in the beacon and transmitted for notification (step T123c). This information is not limited to being included in the beacon. It is sufficient if notification to an unspecified device is possible.

  The primary selection depends on a combination of one or more of the following criteria: First, if there is a processing unit that is temporarily defective or unstable in each unit of the server device, the parameter notification unit 123b that requires the operation of the processing unit is excluded. Next, when the user of the server device is not close to the server device or the server device is placed at a position where the user of the client device cannot operate, “manual input” and “storage medium” Except for the parameter notification means 123b.

  Next, in the case where the server device is installed such that the location of the server device is not visible or the display unit 105 of the server device is not visible, in addition to “storage medium”, “two-dimensional code” Except for the parameter notification means 123b. Next, selection is performed by an instruction designated by a predetermined key operation of the input device 106.

  When the information for identifying the parameter notification unit 123b in step T123c is notified, the wireless LAN communication unit 123 of the server apparatus may transmit the parameter notification unit 123b with priority. This priority is determined by one or more of the security 123c of the parameter notification means priority 123a, the effort 123d, the required time 123e, the distance 123f between them, and the penetration rate 123g.

  Moreover, it determines with the attribute of communication with the client apparatus which the server apparatus assumes. For example, when communication of information with a high degree of secrecy is assumed, the priority of a means with a low security 123c is set high. Further, when communication with many client devices is desired, the priority of the means having a small distance 123f between the two is set high.

  Note that the wireless LAN communication unit 123 of the server device may select one parameter notification unit 123b by the primary selection process in step T123b. In addition, the wireless LAN communication unit 123 of the server device may always select one specific parameter notification unit 123b. In these cases, the process of selecting the parameter notification unit 123b by the wireless LAN communication unit 123 of the client device described later is unnecessary.

  The wireless LAN communication unit 123 of the client device receives the beacon transmitted in step T123c (step S123c), detects the server device (step S123d), and parameter notification means indicated by the identification information included in the beacon 123b is analyzed to recognize which means can be selected (step S123e).

  Then, the wireless LAN communication unit 123 of the client device displays information for identifying the server device detected in step S123d on the display unit 105 (step S123f), and the input to the server device is performed by a predetermined key operation of the input device 106. A connection request is input (step S123g). Note that the connection request to the server device in step S123g is not necessarily due to a key operation of the input device 106. For example, a processing unit in the client device that performs the communication using the wireless LAN communication unit 123 of the client device may request the processing unit that activates the wireless LAN communication unit 123.

  If the client device cannot use any of the means recognized in step S123e, the wireless LAN communication unit 123 of the client device does not perform an operation subsequent to the information display operation for identifying the server device in step S123f. It is also good. Further, the display operation may be performed and the input operation and subsequent operations in step S123g may not be performed.

  When the connection request is input in step S123g, the wireless LAN communication unit 123 of the client device selects one means from the parameter notification means 123b analyzed in step S123e (step S123h). This selection depends on one or more combinations of the following criteria: If no means is selected by this selection, that is, if any notification means cannot be executed, the wireless LAN communication unit 123 of the client apparatus ends the operation without connecting to the server apparatus.

  First, when the client device does not include a processing unit necessary for acquiring a parameter by notification by the parameter notification unit 123b, the parameter notification unit 123b is excluded. Next, if there is a processing unit whose operation is temporarily defective or unstable in each unit of the client device, the parameter notification unit 123b that requires the operation of the processing unit is excluded.

  Next, it is determined according to the attribute of communication with the server device assumed by the client device. For example, when communication of information with high confidentiality is assumed, the parameter notification unit 123b having a low security 123c is selected. Further, the distance to the server device is estimated based on the quality of the radio wave of the beacon received in step S123c, for example, the strength or the signal-to-noise ratio. The farther the estimated distance is, the smaller the distance 123f between the two is. The parameter notification unit 123b is selected. Next, the server device selects the parameter notification unit 123b with a high priority. Next, the input device 106 is selected by a predetermined key operation.

  Subsequently, the wireless LAN communication unit 123 of the client device transmits information for identifying the selected parameter notification unit 123b to the server device (step S123i). The wireless LAN communication unit 123 of the server apparatus receives this information (step T123d), and notifies the parameter 108a by the selected parameter notification unit 123b (step T123e).

  That is, the wireless LAN communication unit 123 of the server device retrieves the parameter 108a whose parameter flag 108d of the own device is “parameter of own device” from the parameter storage unit 108, thereby obtaining the identifier 108b and the personal identification information 108c.

  When the selected parameter notification unit 123b is “barcode”, the wireless LAN communication unit 123 of the server device transmits the obtained identifier 108b and the password information 108c to the two-dimensional barcode generation unit 121. Then, it is converted into a two-dimensional barcode and further displayed on the display unit 105.

  When the selected parameter notification unit 123b is “manual input”, the wireless LAN communication unit 123 of the server apparatus does not perform the operation of notifying the parameter in step T123e. That is, the parameter 108a is transmitted verbally from the user of the server device to the user of the client device.

  Note that in the case of this “manual input”, the operation of notifying this parameter is not limited, and the wireless LAN communication unit 123 of the server device displays the obtained identifier 108b and the password information 108c. You may display as a character on the part 105. FIG. The displayed parameter may be visually recognized by the user of the server device, or may be visually recognized by the user of the client device.

  When the selected parameter notification unit 123b is “storage medium”, the wireless LAN communication unit 123 of the server device connects the obtained identifier 108b and the password information 108c via the storage medium connection unit 131. Write to the recorded storage medium. Before the writing, an instruction to connect the storage medium via the storage medium connection unit 131 is displayed on the display unit 105, and an input to the effect that the connection is completed is performed by a predetermined key operation of the input device 106. You can wait for what has been done.

  When the selected parameter notification means 123b is “infrared communication”, the wireless LAN communication unit 123 of the server device controls the infrared communication unit 125 to obtain the identifier 108b and the password information 108c, Send it. Needless to say, before and after the transmission, it is necessary to connect a transmission line according to the IrDA standard, for example.

  When the selected parameter notification unit 123b is “Bluetooth communication”, the wireless LAN communication unit 123 of the server device controls the Bluetooth communication unit 124 with the obtained identifier 108b and the password information 108c, Send it. Needless to say, a transmission line connection in accordance with the Bluetooth (R) standard is required before and after the transmission.

  When the selected parameter notification unit 123b is “mobile communication network communication”, the wireless LAN communication unit 123 of the server device controls the transmission / reception unit 103 to transmit the obtained identifier 108b and password information 108c. , Send. Needless to say, before and after the transmission, it is necessary to connect a transmission path via the mobile communication network.

  The wireless LAN communication unit 123 of the client device acquires parameters for connecting to the server device by the parameter notification unit 123b selected in step S123h (step S123j).

  That is, if the selected parameter notifying means 123b is “bar code”, the camera 107 is caused to capture a two-dimensional bar code to acquire the parameter. Note that the two-dimensional barcode captured by the camera 107 is displayed on the display unit 105 of the server device. The operation when the selected parameter notification means 123b is “bar code” will be described in detail later.

  When the selected parameter notification unit 123 b is “manual input”, the wireless LAN communication unit 123 of the client device acquires a parameter by a predetermined key operation of the input device 106.

  When the selected parameter notification unit 123b is a “storage medium”, the wireless LAN communication unit 123 of the client apparatus reads out the parameters stored in the storage medium connected via the storage medium connection unit 131. Get the parameters. Prior to this reading, an instruction to connect the storage medium via the storage medium connection unit 131 is displayed on the display unit 105, and an input to the effect that the connection is completed is performed by a predetermined key operation of the input device 106. You can wait for what has been done.

  When the selected parameter notification unit 123b is “infrared communication”, the wireless LAN communication unit 123 of the client device acquires the parameters by controlling the infrared communication unit 125 to receive the parameters. Needless to say, before and after the reception, it is necessary to connect a transmission path according to the IrDA standard, for example.

  When the selected parameter notification unit 123b is “Bluetooth communication”, the wireless LAN communication unit 123 of the client device acquires the parameters by controlling the Bluetooth communication unit 124 to receive the parameters. Needless to say, before and after the reception, it is necessary to connect a transmission line in accordance with, for example, the Bluetooth (R) standard.

  When the selected parameter notification unit 123b is “mobile communication network communication”, the wireless LAN communication unit 123 of the client device acquires the parameters by controlling the transmission / reception unit 103 to receive the parameters. Needless to say, before and after the reception, it is necessary to connect a transmission path via the mobile communication network.

  Subsequently, the wireless LAN communication unit 123 of the client device connects to the wireless LAN communication unit 123 of the server device (step S123k, step T123f), and both perform authentication processing using the acquired parameters (step S123m). Step T123g).

  Subsequently, both perform connection completion processing (step S123n, step T123h), and the wireless LAN communication unit 123 of the server device further performs parameter notification processing (for example, display on the display unit 105) performed in step T123e. If the operation continues), the process ends (step T123i), and both perform predetermined communication (not shown).

  If the wireless LAN communication unit 123 of the server device does not perform the operation of notifying the parameter of step T123e, naturally, the operation of ending the parameter notification process of step T123i is not performed.

  The predetermined communication may be, for example, communication by a file transfer application or communication by a chat application. In addition, at the start of these applications, authentication for each application may be performed. This authentication is irrelevant to the authentication performed by the wireless LAN communication unit 123 using the parameter 108a.

(Details of operation when notifying parameters using 2D barcode)
Next, the processing in the case where the parameter notification means 123b selected in step S123h is “bar code” will be described in detail. FIG. 6 shows a flowchart of the operation of the wireless LAN communication unit 123 when the parameter notification unit 123b selected in step S123h is “barcode”. In addition, about the same part as the content demonstrated with reference to FIG. 4, illustration is abbreviate | omitted or attaches | subjects the same code | symbol and abbreviate | omits description.

  The wireless LAN communication unit 123 of the client device inputs the connection request to the server device in step S123g, and then selects the parameter notification unit 123b that is “barcode” (step S123h-2), and sets the parameter using the two-dimensional barcode. Is notified to the wireless LAN communication unit 123 of the server device (step S123i-2).

  Upon receiving this request (step T123d-2), the wireless LAN communication unit 123 of the server device controls the two-dimensional barcode creating unit 121 to convert the parameter 108a of the own device into a two-dimensional barcode, Are displayed on the display unit 105 (step T123e-2).

  The wireless LAN communication unit 123 of the client device activates the camera 107 after making the request in step S123i-2 (step S123j-2), and captures the two-dimensional barcode on the camera 107 by a predetermined key operation of the input device 106. (Step S123i-3) The two-dimensional barcode analysis unit 122 is controlled to convert the two-dimensional barcode output from the camera 107 into a parameter (Step S123j-4).

  Thereafter, the wireless LAN communication unit 123 of the client device and the wireless LAN communication unit 123 of the server device perform the operations after Step S123k and Step T123f already described. The operation of the wireless LAN communication unit 123 of the server device for ending the parameter notification in step T123i will be specifically described. The operation of the two-dimensional barcode generation unit 121 is ended, and the two-dimensional barcode generation unit 121 is also combined. The display on the display unit 105 is erased (step T123i-2).

(Embodiment in which primary-selected parameter notification means 123b does not include “manual input”)
Next, the wireless LAN communication unit 123 of the server apparatus does not select “manual input” at the time of the primary selection of the parameter notification unit 123b in step T123b. Therefore, the parameter notification unit 123b that becomes “manual input” in step T123c. The operation in the case where the information for identifying is not transmitted in the beacon will be described.

  The reason for specifically explaining the operation in this case is as follows. That is, the parameter notification means 123b for “manual input” is inferior from the viewpoint of the labor 123d and from the viewpoint of the required time 123e as already described. In addition, there is no possibility that the user may feel uncomfortable when an error is mixed in the key operation of the input device 106 by the user and the authentication fails.

  Therefore, the parameter notification means 123b of “manual input” is basically not used, and is used only when the other means cannot be used to notify the parameter by an appropriate method.

  FIG. 7 shows a flowchart of the operation of the wireless LAN communication unit 123 when “manual input” is not selected in the primary selection of the parameter notification unit 123b in step T123b. In addition, about the same part as the content demonstrated with reference to FIG. 4, illustration is abbreviate | omitted or attaches | subjects the same code | symbol and abbreviate | omits description. Therefore, illustration and description of the operation of the wireless LAN communication unit 123 of the server device are omitted.

  The wireless LAN communication unit 123 of the client device checks whether or not at least one of the parameter notification units 123b analyzed in step S123e can be executed by the client device after inputting a connection request to the server device in step S123g. (Step S123h-6). In order to check whether or not execution is possible, the processing already described in the operation of step S123h is applied mutatis mutandis. If possible, the operation after selecting the notification means in step S123h already described is performed.

  On the other hand, if impossible, the wireless LAN communication unit 123 of the client device causes the display unit 105 to display a prompt for manual parameter input (step S123h-7), and inputs the parameter by a predetermined key operation of the input device 106. (Step S123h-8), and using the parameter acquired by the input, the operation after the wireless LAN connection with the server device in Step S123k is performed.

  If this is not possible, the wireless LAN communication unit 123 of the server device does not perform the operation of notifying the parameter of Step T123e, and therefore does not perform the operation of terminating the parameter notification of Step T123i.

  In the above description, the user of the client device already knows the parameter 108a of the server device, or is verbal to the user of the server device, in a call via the mobile communication network communication unit 102, or otherwise. Although the server apparatus parameter 108a is known by asking using means, the present invention is not limited to this.

  For example, if the wireless LAN communication unit 123 of the client device is not possible in step S123h-6, the parameter notification unit 123b “manual input” is selected in step S123h, and the notification of the parameter in step S123i is requested. It is also possible to perform subsequent operations. In this case, the wireless LAN communication unit 123 of the server apparatus performs an operation for notifying the parameter at Step T123e and an operation for terminating the parameter notification at Step T123i.

(Mode in which client device transmits beacon)
Next, the operation of the wireless LAN communication unit 123 in a form in which the mobile communication terminal device 100 serving as the client device transmits a beacon will be described.

  FIG. 8 shows a flowchart of the operation of the wireless LAN communication unit 123 in a form in which the mobile communication terminal device 100 as a client device transmits a beacon, and the left side of the figure shows the operation of the wireless LAN communication unit 123 of the device as a client device. The right side of the figure shows the operation of the wireless LAN communication unit 123 of the device serving as the server device.

  In addition, about the same part as operation | movement of the wireless LAN communication part 123 in the form which the mobile communication terminal device 100 used as a server apparatus demonstrated with reference to FIG. 4 transmits a beacon, the same code | symbol is attached | subjected and description is abbreviate | omitted. .

  In step S123b, the wireless LAN communication unit 123 of the client device detects the presence / absence of each processing unit and the presence / absence of operation abnormality, and then obtains parameters necessary for logging in to the server device. The primary selection is made (step S123r), and information for identifying the selected parameter notification means 123b is included in the beacon and transmitted for notification (step S123s).

  Here, the primary selection process in step S123r conforms to the primary selection process in step T123b in the operation of the wireless LAN communication unit 123 of the server apparatus described with reference to FIG. The beacon transmission process in step S123s is the same as the beacon transmission process in step T123c in the operation of the wireless LAN communication unit 123 of the server device.

  After being activated in step T123a, the wireless LAN communication unit 123 of the server apparatus receives the beacon (step T123r), and at least one of the parameter notification units 123b indicated by the identification information included in the beacon is If it can be executed by the server device, one of the executable parameter notification means 123b is selected (step T123s). Then, the selected parameter notification unit 123b is transmitted as a part of the response indicating that connection to the client device is possible (step T123t), and the operation after the parameter notification is performed by the selected unit in step T123e is performed.

  Here, the process of selecting the notification unit in step T123s conforms to the process of selecting the notification unit in step S123h in the operation of the wireless LAN communication unit 123 of the client device. In the operation of notifying the parameter by the selected means in step T123e, the means selected in step T123s is notified.

  The wireless LAN communication unit 123 of the client device receives the response (step S123t), and performs the processing after the detection of the server device in step S123d already described. However, the analysis process of the notification unit in step S123e, the selection process of the notification unit in step S123h, and the process of transmitting the selected notification unit in step S123i are unnecessary. This is because the notification means has already been recognized in step S123t. The parameter acquisition operation in step S123j is performed by the notification means received in step S123t.

  For example, when the parameter notification unit 123b “barcode” is selected in step T123s, the operation of acquiring the parameter of step S123j is the operation of starting the camera 107 of step S123j-2 described with reference to FIG. To the operation of obtaining the parameters by controlling the two-dimensional barcode analysis unit 122 in step S123j-4.

  In addition, the operation of notifying the parameter in step T123e is an operation of controlling the two-dimensional barcode creating unit 121 in step T123e-2 described with reference to FIG. 6 to display the two-dimensional barcode on the display unit 105. .

  Note that the wireless LAN communication unit 123 of the client device does not select “manual input” at the time of the primary selection of the parameter notification unit 123b in step S123r. Therefore, the parameter notification unit 123b that is “manual input” is selected in step S123s. When the information to be identified is not included in the beacon and transmitted, the mobile communication terminal device 100 serving as the server device described with reference to FIGS. 4 and 7 performs the primary operation of the parameter notification unit 123b in step T123b. This is the same as the operation when “manual input” is not selected at the time of selection.

  That is, the wireless LAN communication unit 123 of the client device checks whether or not the notification unit in step S123h-6 described with reference to FIG. 7 can be executed after the operation of inputting the connection request in step S123g. If it is not feasible, the operation of acquiring parameters by manual input in steps S123h-7 and S123h-8 may be performed.

  In the above description, the wireless LAN communication unit 123 of the server apparatus does not select a plurality of means during the selection operation of the notification means in step T123s, but the present invention is not limited to this.

  When a plurality of notification means are selected, the wireless LAN communication unit 123 of the server device transmits the notification means as a response at step T123t, and the wireless LAN communication unit 123 of the client device is described with reference to FIG. The notification means selection operation in step S123h and the notification request by the selected means in step S123i are performed. And the wireless LAN communication part 123 of a server apparatus should just perform the reception operation | movement of the said request | requirement of step T123d.

  In particular, when there is no user of the server device in the vicinity of the server device, a process in which the client device finally selects the notification unit may be effective. For example, the server device is used as a bulletin board for information notification in one direction, and the information is received by various client devices. In this case, it may be difficult for the server device to select the optimal notification means for any of a wide variety of client devices.

  In the above description, the process of appropriately notifying the parameters necessary for the wireless LAN connection by the wireless LAN communication unit 123 has been described as an example. However, this process is performed using parameters necessary for other connections. Of course, it can be applied to appropriate notifications. For example, the present invention can also be applied to parameter notification processing required for Bluetooth (R) connection by the Bluetooth communication unit 124.

  In any case, by applying the present invention, the operation of the user of the apparatus is minimized, and the parameter can be notified by an appropriate means. For example, when a parameter is notified via a two-dimensional barcode, the user only needs to photograph the two-dimensional barcode by the user of the client device. An operation for starting the camera 107 for displaying the two-dimensional barcode, erasing the display, and photographing is not necessary. In addition, a high level of proficiency is not required for the user of the apparatus. The present invention is not limited to the above configuration, and various modifications are possible.
